Technology – The Best Linux Apps


To maximize your experience on Linux, there are numerous useful applications available. These include:

  • Firefox Browser,
  • Thunderbird email client,
  • LibreOffice office suite,
  • VLC Media Player,

and many more.

Read on to discover the best Linux apps for your system! Listed below are some of our favorites. Don’t miss out on these useful programs! And be sure to download them for free. You won’t regret it. Just follow these easy steps to maximize your use of Linux!

Firefox Browser

Mozilla Firefox is one of the best Linux apps, but it takes a little bit of memory. To reduce this, deactivate or delete unnecessary add-ons from the browser. To do this, open the Add-ons menu and select the deactivate or delete option for any add-ons you no longer need. If you like using colorful Mozilla Firefox browser themes, however, they may slow down your browsing.

Mozilla Firefox is open source software that implements many web standards, including HTML, XML, XHTML, MathML, SVG 1.1 and SVG 2, and ECMAScript extensions. Other features include support for APNG images with alpha transparency, a custom theme system, Gecko layout engine, and SpiderMonkey JavaScript engine. Mozilla Firefox is free and open-source, and is compatible with most major operating systems. It is written in C++ and Javascript, and is free software. It is licensed under the MPL 2.0.

In addition to Firefox, other free and open-source browsers are available on Linux. Falkon, formerly known as Qupzilla, is a popular desktop browser in KDE. It has built-in email and newsgroup clients, saving users from switching apps. Other browsers on Linux are also available, and some are designed for specific purposes. Despite their name, they are lightweight and free. Not all web browsing can be done with a graphics-based browser. In the early days, text-based command-line browsers were essential. These browsers are known as “terminal” browsers, and you navigate through them by using the arrow keys. The commands are then displayed in the terminal window.

Thunderbird email client

In order to install Thunderbird, follow the instructions on the website. To get started, download Thunderbird from the website. If it is open, click the Close button at the bottom of the window. Next, install the necessary libraries. You need to install libstdc++5, which many distributions do not include by default. Once you’ve installed the libraries, launch Thunderbird by typing the command thunderbird. If you don’t have libstdc++5, it will not start.

While it looks clean, it lacks the modern features of other email clients, such as an address book and calendar. For those who do not need these features, though, Geary is an excellent choice. If you don’t need a full email client, Geary is the best option. While it lacks some modern features, such as an address book and calendar integration, it is a great choice for users who do not want a complex and advanced email client.

Thunderbird is open source, and you can help make the software better by contributing ideas and code. In addition, you can contribute your time to the project by helping other users. By helping others, you can give your feedback on the final release. If you don’t feel like creating new features, Thunderbird can automatically detect the format of your messages. If your emails are too large to fit in a folder, Thunderbird can send them as plain text.

LibreOffice office suite

For those who prefer the familiarity of Microsoft Office, LibreOffice is among the best Linux apps. The software’s native file format is Open Document Text (ODT). However, LibreOffice can also read and write Microsoft Word files, though its accuracy is not as good as Microsoft’s. The good news is that LibreOffice offers an optional user interface called NotebookBar, which unites the toolbars into tabs. This allows users to switch between toolbars easily, and it’s more flexible than Microsoft Office.

One of the most popular uses of LibreOffice is in the business world, where it helps create and edit documents. Users can also translate documents using this program. It supports multiple languages, and is available for download for free. LibreOffice is among the best Linux apps for business use. However, it is not without its flaws. If you are concerned about compatibility, you can always try installing the ttf-mscorefonts package. However, it is not the official way of installing Microsoft fonts in Linux.

VLC Media Player

The packet-based media player, VLC, plays nearly all types of video content, from MPEG-4 to HDV. It’s also capable of playing files that are damaged, incomplete, or unfinished. You can also use it to play files that are still downloading through a P2P network, as well as play HDV camera files through a FireWire cable. VLC is also a versatile tool for creating basic playlists and bookmarks. Aside from being powerful, it’s lightweight and fast, with customizable hotkeys that help you customize the player.

While there are many other video players available, few are as versatile as VLC. It plays most types of media, streams YouTube videos, and records microphone and voice messages. VLC is easy to use, primarily through single-letter key presses and a right-click menu. You can also convert file formats, create playlists, and keep track of your media library. In short, VLC is one of the best Linux apps for playback of media files.

Shotcut video editor

If you’ve been considering switching from Windows to Linux, you might want to consider the Shotcut video editor for Linux. This multiplatform application supports several popular video formats, including HTML5 and MOV, and has plenty of features for basic editing tasks. It also comes with a range of tutorial videos that can show you how to use its features and get started quickly. However, you must be aware that Shotcut is not a professional-level tool.

If you’re running Ubuntu, you can easily install Shotcut for Linux. To install this application, open the Ubuntu main menu and type “shotcut” into the search box. The program should show up in the top result. After that, double-click it to install it. If you’d rather use a terminal, you can install the application from the command line. Make sure to enter a password, as you won’t be able to run it from the main menu unless you have root privileges.

GIMP art and design app

The GIMP art and design application for Linux offers many tools for editing photos, drawings and documents. You can use various editing tools like a paintbrush, pencil, airbrush, eraser, ink tool and others to create the perfect piece of artwork. Other tools include a bucket fill tool that can fill a selection with a color or pattern, a blend tool for blending colors, and a Smudge tool for smearing. GIMP offers 150 standard filters and effects.

The GIMP art and design application is free to download and run. It’s compatible with a variety of platforms and supports a number of programming languages. The open-source program can be customized to meet your individual needs. There are many 3rd-party plugins for GIMP that enhance the program’s performance and efficiency. You can use GIMP to retouch photos, edit them, create icons, and design print designs.

Audacity music editor

If you want to create your own music, Audacity is an excellent choice. Whether you’re a seasoned musician or a newbie, this open-source music editor is great for recording and editing music. Its free-to-download nature makes it an excellent choice for any Linux user. Audacity is available from the package manager, as well as from its official website.

While Audacity is available for free, it has been controversial since it was first released in 2004. Its privacy policy recently changed and now collects data that can be used for law enforcement, litigation, and authorities’ requests. Some users complained about this policy change, and the group has since apologized and backed off on the move. Until further notice, you can still download the latest version of Audacity from its website and install it with your package manager.

In addition to supporting Ogg Vorbis, Audacity also supports a wide variety of audio formats. Moreover, it is capable of generating files in various formats, including MP3 and FLAC. Additionally, Audacity supports plugins, which make it possible for users to create their own. The program has a plugin manager, which lets you manage your favorite plugins.

Visual Studio Code editor

There are many reasons why Visual Studio Code editor is one of the best applications for Linux. It’s open-source, easy to use, and comes with a wide variety of features. Visual Studio Code includes an optional C++ compiler that uses Microsoft’s code generation technology and the clang front end. It also supports native file system APIs, making it a viable alternative to the free and open-source Code – OSS editor.

This code editor is free and has thousands of extensions available. Many of these extensions are free and install seamlessly, making them a breeze to install. You can customize almost every feature with the help of the extension store, which contains a large community of developers. It has one of the best UIs of all code editors, and it’s lightweight and fast. It’s also packed with useful features, such as interactive filters, search and replace, and the ability to name files directly in the editor. The side-by-side code windows help you navigate the code with ease.

If you’re a serious programmer, Visual Studio Code is an excellent choice. It offers a feature-rich code editor for Linux, including hundreds of languages, and an extension system that makes developing plug-in kits easier than ever. You’ll also enjoy IntelliSense and intelligent code completion, as well as automatic code refactoring and auto-indentation. If you’re working in multiple programming languages, Visual Studio Code is also a great option. You’ll never have to open another IDE again!

VirtualBox virtual machine app

To start using the VirtualBox virtual machine app on Linux, first download and install the free software from Oracle. You can install the program anywhere on your computer, and it works with any distribution of Linux. Next, open the downloaded file. Make sure to choose the correct operating system, version, and disk space. In the “Startup Disk” window, select the Linux ISO file. Then, follow the instructions for setting up the virtual machine.

After installing VirtualBox, choose an operating system. You can choose between 32-bit and 64-bit versions. VM apps support MacOS, which lets you test out the OS before using it on your PC. ARM operating systems run best on QEMU, which is command-line-based and easy to install. Once you’ve installed the software, you can customize the settings for your VM, such as graphics, hardware, and storage.

When using the VirtualBox virtual machine app on Linux, be sure to boot from the operating system that you’re using. Then, select the named virtual machine. When it’s ready, click “Start” to boot into the virtual machine. When you’ve finished, you can shut down the VM and restart it from a saved state. You can also power off the virtual machine. If you have a VM on your Linux system that you’re not using, you can use the same steps to shut down it.

After installing VirtualBox on your Linux-based PC, you can edit the name and other settings of the VM. You can also enable shared clipboard, drag-and-drop, and disable the virtual floppy drive. You can also configure acceleration and select one of the two emulated chipsets. The Screen tab lets you customize video memory. You can also connect to the guest OS remotely and manage it using the Remote Display tab.

Another popular virtual machine app on Linux is GNOME Boxes. Fedora includes it as the default VM. This is a simple, user-friendly VM, which is a front-end to KVM, Qemu, and libvirt. It has a very simple setup wizard and a lot of competitive functions. It can load an OS image from a URL if it is not available on your computer.

ClamAV antivirus app

If you use Linux, you’re probably familiar with the ClamAV antivirus app. It’s a powerful antivirus program with excellent rates of malware detection. It runs directly from an open-source repository, which means that it’s very easy to install and configure. ClamAV has a very comprehensive scanner, and is capable of looking through most archive types, ELF executables, popular office documents, and portable executable files.

Its free antivirus scanner detects all types of viruses, malware, and trojans. It’s also capable of scanning all kinds of mail file formats. Although Linux doesn’t support some of the popular virus scanning software found on Windows or Mac OS, the lightweight, customizable ClamAV antivirus app is a great addition to your system. You can also scan for spam, phishing, and ransomware with the antivirus app.

The open-source ClamAV antivirus app for Linux detects viruses on most platforms, including Ubuntu. The app is available for installation via the Synaptic Package Manager and Software Center. Once installed, ClamAV can be configured to load into memory only when needed or to connect to a daemon to run in the background and automatically download database updates. You can install ClamAV by installing the clamav-daemon package, and the clamav-freshclam package.

Although viruses, malware, and Trojans are very rare on Linux, they can still cause havoc on your system. With ClamAV, you can scan email, online files, and endpoints with ease. The multi-threaded daemon and command-line scanner are great options for security, and the antivirus app is lightweight, so that it won’t impact your system’s performance. You can also check if a file has a rootkit by using the free Chkrootkit tool.

ClamAV is an excellent choice for Linux users because it supports numerous archive formats. It also supports Portable Executable files, ELF executables, and obfuscated executables. Furthermore, it’s capable of detecting malware, viruses, and worms, even on files outside of its library. Its signature database is constantly updated, and it’s easy to update. While it’s not as detailed as ESET NOD32, it’s still a fantastic security tool for your system.

Rsync transfer and sync of files

The -file-from option lets you specify a list of files to transfer. This option modifies rsync’s default behavior and allows you to sort the files on the receiving end. With this option, you will avoid recursions and maintain the information about the files in the specified path. The -file-from option also forces the creation of directories on the receiving end, avoiding the creation of redundant files.

In addition to Linux, rsync is available in macOS, *BSDs, and other Unix-like operating systems. You can use rsync on the command line, or use scripts to automate the process. Some tools wrap rsync in an easy-to-use UI. If you’re looking for a simple, reliable way to transfer files between computers, rsync can help you out.

The -max-delete option limits the number of files that can be deleted before exiting the program. This option limits deletions to NUM files or directories, and if you exceed this limit, the process outputs a warning message. This option is backward-compatible, but it is not recommended if you’re using an older client. Using -max-delete is the recommended choice for rsync.

To exclude a specific file or directory, you can specify a ‘-k’ suffix. Alternatively, you can specify a maximum file size by -max-size option. In both cases, the command will attempt to match all the files and directories in the list with the matching patterns. When you specify a limit, rsync will skip those files that don’t match any patterns.

rsync also provides options to limit the size of files that can be transferred. The –max-size flag prevents rsync from transferring files larger than the specified size. With this option, rsync will use the partial-dir as a staging area for the copied files. The –max-size flag doesn’t have any side-effects when using an absolute path.

rsync can be used on many different platforms. As a powerful command line utility, rsync enables file synchronization between two systems. It is useful in backups, mirroring, and general day-to-day use. Moreover, rsync is available on virtually every Linux-based system. So, regardless of operating system, you’re sure to find rsync useful.

Timeshift backup driver and configuration changes

To use Timeshift, run its setup wizard and follow the steps to configure the device. Select the backup destination and specify the backup method. If you want to backup only certain files, choose RSYNC. Otherwise, select BTRFS, which requires BTRFS tools installed. If you choose BTRFS, the backup will be created only to the system directory. For more information, see the Timeshift user guide. When Timeshift is configured, the backup starts automatically and displays a list of files and folders.

To restore a snapshot from Timeshift, simply choose “Restore from snapshot.” The restore process will take a few minutes. You can also use the Timeshift live DVD or live cd to restore a previous working snapshot. Delete a snapshot is easy. The backup copy will be deleted, but the relevant files will still be retained. Scheduled backups will retain selected snapshots. In this way, you can restore your system to a previous state without having to worry about losing your important files.

To make your backups automatically, Timeshift can be configured to run on a scheduled basis. By default, it will create a backup at regular intervals of approximately one hour. You can adjust this schedule to create a snapshot whenever you need one, or you can schedule them to run once a day. When you have finished making the changes, Timeshift will run again. Its snapshots are stored on an external storage device so that you can restore them in case of an unstable operating system.

Once your Timeshift application has been installed, you can start scheduling a backup. The wizard will let you choose how often you want to run the backups. Once you’re set up, you’ll be prompted to enter a schedule for backups. You can choose between two backup methods: rsync and BRTFS built-in file system features. If you prefer the rsync method, your backup will be the largest.

Timeshift offers a range of options for your backups, including user home directory and system snapshots. You can also specify files and directories to exclude from snapshots. A single-step restore from any snapshot can be used to get your computer back up to the time it was when the snapshot was created. You can restore a backup or delete it at any time, depending on your preferences. If you’d like to restore the backup, Timeshift also allows you to browse the directory containing your backup.

Technology – The Top 5 Linux Commands


There are many useful commands on Linux, but these are the most commonly used. These will give you more power and more flexibility. Let’s go over the most important ones. The top 5 are:

  • cd
  • chmod
  • cmp
  • ls
  • pwd

First, ls is a command that lists files and folders in a directory. There are dozens of options available, including filename, type, size, permissions, owners, and date created/modified. grep is another command that searches specific files and lines of code.

The ls command displays the contents of a directory or file. It is useful for listing directories and files. It can produce multiple symbolic links to the same file. The cmp command compares two files and prints out the results. Often programmers use the diff command to make alterations to their code. While ls is a useful tool, the tar command is most often used for archiving multiple files. The pwd command provides the current working directory.

Another useful command is rm -rf. Using this command, you can enforce directory deletion. The chroot command allows you to run an interactive shell in a special directory. The rm command allows you to change the user password. It also enables you to reset the password. A simple chmod will change the owner of a file. Several commands are also useful to do common tasks. The most popular ones include pwd, ls, and cd.

The Cd command in Linux allows you to change the current working directory to another location. You can specify the directory’s absolute pathname or local pathname. The latter is usually more convenient and often is more appropriate for most users. The following is a list of useful options for cd. To use the cd command, press the TAB key while typing the directory name. The following example demonstrates how to change the current directory to a different location.

To change your directory, use the cd command. It changes your current directory to the previous one. This command is useful when you need to change the directories or you need to change the working directory within a certain directory. It can also change the current directory multiple levels up or down. Learn to memorize the cd command in Linux and you’ll be well on your way to becoming a more efficient system administrator.

The cd command accepts two parameters: -L and -D. When used with the -L option, it follows symbolic links. Otherwise, it defaults to the home directory. You can use the -D options to switch between directories. If you want to change your working directory to a different user’s home directory, use the -L option to specify the current directory.

The ls command is one of the most commonly used Linux commands. It lists the contents of a directory. It can be combined with other commands to sort and view hidden files. In addition, ls can show the current working directory. However, ls does not provide metadata about files. If you want to access this information, you can use ls -l. It will return the contents of a directory in MB format.

The iptables command allows system administrators to control the flow of internet traffic on their systems. The iptables command lets system administrators define the types of network traffic. They can blacklist or allow legitimate network requests. Aside from being a helpful command, it can be used to perform various tasks. It is a popular program, and is very simple to use. The iptables command also allows administrators to filter internet usage.

Aside from ls, rmdir is another commonly used command. It is used to delete directories and files. Using the rmdir command, you can delete a directory. After removing it, the directory will be removed from the system. To clear the Linux window, type clear and press enter. This command will clear the terminal. In short, you should know about these common Linux commands. These are just a few of the most common.

ls is a popular command. It lists files and directories in the current directory. ls is a powerful command, but it doesn’t do all the necessary things. It does, however, have other functions. For example, it can list files and directories in the current directory. Aside from that, it can also list the file and directory contents. It is also useful for displaying the current working directory.

rmdir is one of the most popular Linux commands. It will help you remove directories or files from a particular location. This is useful when you need to remove large files or directories, and you want to ensure that they are deleted. You can also clear the terminal by pressing the rmdir command. If you want to delete a directory, you need to type clear and press enter. Then, you need to make sure you delete files or folders.

The find command is useful for finding files. It will check whether the file was created or modified within the past week and remove older files. The ps command will check for processes running on the system. It will return the process PID and the CPU/RAM usage. And finally, grep will remove a directory. So, these are the most useful Linux commands. You can use them as often as you want. You can even learn new ones by doing research online.

The ls command is the first command that almost all Linux users will use. It will list all the files and directories in a directory. It will also list the directories in the nested directories. All these commands can help you to make your life easier when using a Linux operating system. Just remember that these commands are essential for every Linux user. They can help you to create a bootable live USB stick and much more.

Technology – What The Tail Command Does in Linux


The tail command in Linux displays the last few characters of a file. Since each character is a single byte, it can be used to script a file. The command works by printing the contents of a file as it shrinks. It also follows a file, no matter its descriptor or rename, displaying a message when it reaches a certain size. Learn more about how to use the tail command.

The tail command is a very useful tool for system administrators. Without options, it simply prints the last x lines of a file. With -f, you can monitor changes in log files by updating only the first ten lines. To get more information on this command, try using man, a command in the man manual. You can use this to see the documentation of the command. When learning how to use tail in Linux, make sure to learn its capabilities.

When you use the tail command, you can see the last ten lines of a file in the terminal. You can also use -n, which limits the number of lines to be printed. This option is useful when you want to keep track of many files at once. If you need to see the last ten lines of a single file, use -c. The latter option limits the number of bytes to be displayed.

The tail command is an excellent tool for monitoring files. It shows the last ten lines of a file and can also combine multiple files into one. It’s useful for analyzing log files. You can use -a, -x, -k, or k+4 to sort a file by modification time. The tail command is more useful when you want to watch for changes. The output will show the last ten lines of a file, as well as a header line indicating which file it is.

When you’re using the tail command, you’ll be able to see the last ten lines of several files. When you use the -h flag, you can view only the last ten lines of one file. When you’re using -c, you can rename the file. Alternatively, you can -l and -f for the same. These commands can be combined with the tail command.

The tail command updates the display of a file every time new data is written to it. It also prints a header identifying the file. The screenshot above shows that it updates the file every two seconds. Each new entry is displayed in the terminal window. The screen will automatically refresh when there are newlines in the file. Similarly, the -f option is used to show changes when the file’s name is changed.

The tail command displays the last ten lines of a file. Its output is a seamless blend of text, not a log file. The -t option specifies the number of lines. It also has an -c flag which limits the number of bytes of data that it prints. The -h flag will stop the tail command from running while the -c flag will stop the output.

In Linux, the tail command prints the contents of a file in the terminal. This command displays every new line in the file. It also includes a header to indicate the file’s title. These lines are displayed in different colors. In the screenshot below, the changes are shown in red. Its output is more detailed when you include a -f flag. When the last -f flag is specified, but this isn’t necessary.

The tail command displays the last few lines of a file. It is used by sysadmins to monitor log files in real-time. When using the -f flag, the tail command monitors a log file in real-time. The -f option keeps the log file in a loop and prints the lines of a new file as soon as the old one is updated. This command is the most common way to display the last few lines of a file.

Linux tail command summary with examples

Technology – Which is Better Bing Or Google?


There is some debate about which search engine is better. However, in general, it’s not that close. Both have their merits. Google is still the “man in the house”, and it has more search results, more relevant ones, and a better understanding of user intent. In addition, the new whole-page algorithm that Bing has implemented has significantly improved its search engine. But there are still some areas in which these two search engines are similar.

In terms of social integration, Bing is slightly ahead of Google, but both search engines have significant advantages over each other. Bing is able to contract with social networks, like Facebook and Twitter. It also has more data on what users are searching for. The result pages on both sites are much more aesthetically appealing. By clicking on a thumbnail, a movie will automatically open. Both services are also faster and have improved load times.

When it comes to privacy, Bing is more user-friendly than Google. While both search engines use the same core algorithm, Bing’s algorithm uses a different approach. It collects data on language and geotagging, while Google uses this information to help users make informed decisions. Although Bing and its competitors share the same market, it’s not enough to claim that they’re completely equal.

In terms of user experience, both search engines are very similar. In fact, Bing’s interface is easier to use. But, unlike Google, it lacks some of the smart features that Google has. Its search engine provides a weather forecast, unit conversions, movie showtimes, and other useful information. But there’s no comparison between the two. So, the answer to the question of which is better is more complicated than a simple Google-Bing battle.

The main difference between the two search engines is the size of their market. Google has a huge market share in the US, while Bing has just 5% in the UK. Both search engines are equally popular, but one has more users. The US market is dominated by Google, and Bing is rapidly expanding. While Bing is smaller than the UK, it is the second-largest in the world.

In the United States, Google is the top search engine, with a third share. It is not as popular in the UK, where it is only used by 5% of the population. It also has a lower market share than the UK, which is governed by the European Union. But, there’s still a huge debate as to which is better. There’s no clear winner in the current situation.

In terms of quality, Bing is the clear winner. Google has a better-developed website, but its algorithms are similar. In contrast, Bing has a greater focus on content. As such, it’s more likely to be a better option than Google, so that the majority of its users will be satisfied with the results it returns. Besides that, Bing is also more popular than its rival.

The other major difference between Google and Bing is their policies regarding mobile search. While both have similar mobile search results, Bing is a bit better when it comes to images. The latter can also be better in video results, but Bing is better in shopping. When it comes to searching, it’s best to use Google’s mobile-first indexing and don’t worry about losing your ranking.

If you’re a marketer, you should know which search engine is better for your business. Having a strong strategy is crucial in the search engine world. And Google may be the leader in the field, but Bing is a fast-growing competitor, and it’s trying to overtake it. There’s no clear winner, but both are worth your time. You can choose whichever is best for your business.

While both search engines offer similar results, they have different strengths and weaknesses. For example, Google is more user-friendly and has an extensive library, while Bing’s search engine isn’t. It also offers the ability to compare searches using multiple filters. But for everyday use, it’s better to use Google’s voice. If you are unsure, try switching between the two.

Technology – Should I Put My Whole Work History on LinkedIn?


You might be wondering if it’s a good idea to put your entire work history on LinkedIn. Your resume is the first thing that employers will see. It’s important to keep it relevant and to keep your experience to a minimum. However, if you’ve been working for a number of companies, it’s important to make sure that you highlight your most recent employment. Treat LinkedIn like a resume, which means that you should provide the past 10 to 15 years with the most recent five to 10 years being the most important.

Generally, the experience section on your LinkedIn profile should be relevant to your resume. Include only roles that are relevant to your current job search, and do not include roles that were held before ten years. Remember to include dates for each role. If you have twenty or thirty years of experience, do not put it on your profile. Instead, focus on the last five to ten years. You can add dates for your previous roles, but you shouldn’t put your entire work history on your profile.

Your LinkedIn profile is an important way for companies to see what you can offer. If you have multiple jobs, you might be wondering whether to include your entire work history. You should only include the most recent positions. If you’ve had several jobs, you should include them all. Your experience section is the most important part of your profile because it’s what employers will use to determine your qualifications for the job. You can use Laszlo Bock’s formula to describe your achievements, which can be useful for your professional development.

The experience section of your LinkedIn profile should support your resume. When listing your work history, make sure to include the roles you’ve had for the past ten or so years. Write a compelling story that shows your successes and adds credibility to your professional journey. Here are a few suggestions to help you create a comprehensive and achievement-based experience section on LinkedIn. Your profile will be much more impressive if it’s complete and includes your work experience.

Unlike a resume, your LinkedIn experience section should support your resume. It should be a well-written summary of your achievements. Your job description should be more than a list of bullet points. It should be a narrative, instead of a list. Your headline should highlight your main objective. You may also want to highlight your most recent experiences. In the case of a company or recruiter, the company’s website should be able to see your profile.

Besides the information you provide on your resume, your LinkedIn profile should also include the roles you’ve held. It’s best to include your latest positions in this section, but avoid including the ones you’ve held for more than a decade. If you’re in a position where you’re looking for a new position, you should focus your LinkedIn profile on your job experience. The company will look for your qualifications and hire you for the job.

Your LinkedIn profile should contain your most recent work history. Putting your entire work history on your profile will make it less relevant to recruiters. It is best to include your most recent job positions and highlights your achievements. When you’re building your professional profile, try to include your most relevant roles. A job title should be prominent and highlighting your achievements should be the main focus. You should also mention your GitHub profile.

Your LinkedIn profile should include your experience. It should highlight the roles you’ve held in the last ten to fifteen years. You should also include your achievements. When you’re describing your experience, try to include as much information as you can. Incorporate your personal information. For example, you can include your hobbies. It’s best to avoid listing personal details and leave them out of your profile.

If you’re writing your experience on LinkedIn, focus on the most recent positions. If you’ve held several different positions in the past, highlight the most recent ones. You can also mention your school projects, GitHub profile, and other achievements. You can also include your achievements and skills. Just remember that your experience section on LinkedIn should be short and simple. It should contain only the most relevant roles. This way, your profile will be more attractive to recruiters.

Technology – How to Search Google by Date


One of the most common questions that people ask is how to filter Google results by date. While older information may be more reliable, you may want to check out the most current results. After all, a few years is a long time to wait for the latest results on a particular topic. You might also be searching for the most recent information on a specific topic or issue. That is why it is helpful to be able to narrow down your results by date.

You can also filter your search results by date. Depending on what you are looking for, you can select the year, month, week, day, hour, or custom dates. For example, if you are trying to find a movie that was released a year ago, you may only want to see results that are from last year. You can even use custom dates to filter your search. It’s all up to you and how you want to use it.

You can also filter Google results by date by using the new before and after commands in the search bar. These commands can help you filter results by date, so that you can get an updated picture of rankings based on the exact day you search. You can also use these commands to find the most recent results. However, make sure that you use the YYYY-MM-DD command before you start typing your query. You can combine this option with Restrict to Range or Filter by Attribute to get the best results.

Once you have set the date range for your search, you can click on the ‘advanced search’ option on the search results page. This option is located on the advanced search page. You can select the date range, time frame, or both to filter your results by date. You can also filter Google results by date by using the dates ‘before’ and ‘after’ commands together. You can also select the ‘after’ command to filter by a specific date or period.

Depending on your needs, you might want to filter your Google results by date. There are two methods for this. Firstly, you can use the ‘advanced search’ command to narrow down your results by period. By using the ‘advanced search mode’ command, you can filter results by date. Once you have chosen a date, you can then use the ‘advanced’ command to limit the results by time.

In addition to the date, you can also filter Google search results by the most recent year, month, week, day, and hour. You can also filter your search by date by adding a time range to your query. If you are looking for a specific product, you can select a specific time period to narrow down the results by date. If you need to limit your search by date, you can use the ‘date’ keyword.

Secondly, you can also filter your search by date. While it may seem cumbersome, this method is quite convenient for users who need to search for certain products or services on a particular day. Simply enter the desired date in the text box and hit enter. Once you have entered the term, click on the ‘date’ option and a drop-down list will appear. Now, the dates will be shown according to the date you entered.

If you want to filter Google results by date, you can select the date range and time range. You can also use the ‘date range’ field in the ‘date’ field. If you choose the date option, you can specify the timestamp of the search term to narrow down the results. Then, you can specify the time period in the ‘date’ field. You can also specify the time and location of the search term.

By using the ‘date’ option, you can filter the Google search results by the most recent year, month, week, day, or hour. You can also choose a custom date range. Then, you can set a filter based on the time range. If you want to search for a specific time period, select the ‘month’ setting. If you want to filter by date, you can select ‘week’ or ‘year.

Technology – Some Pinterest Social Media Alternatives


Some Pinterest social media alternatives may be more fun than the original. While Pinterest is a popular information discovery tool, the site isn’t the only platform that uses images, GIFs, and videos. In addition to the pinboards that Pinterest provides, there are other sites that are just as fun. The following are a few alternatives to the site you’re currently using. Just be sure to check out all of them out to find the one that best fits your needs.

PearlTrees is a Pinterest social media alternative that is similar but not exactly the same. It follows a similar concept, but instead of boards, users follow different types of trees, allowing them to search for similar content and save items with pearls. The interface and user experience are similar to that of Pinterest, so if you’re looking for a simple, fun alternative, try it out! This is a good place to start if you like Pinterest but don’t know much about it.

FoodGawker is another alternative to Pinterest, which is geared towards food lovers. While its concept is similar to that of Pinterest, Pearltrees uses a slightly different method. You can bookmark content and share it with others. This website uses the terms “trees” and “pearls” to refer to content, which allows you to follow your favorite trees and favorites. The main feature of this site is that you can search for recipes and ideas through keywords.

Aside from being a great alternative to Pinterest, there are many other reasons to switch to a different platform. The site is based on what people share, so it can sometimes be hard to find the type of content you’re looking for. If you’re looking for content to share, you might want to consider Juxtapost or Mix. Both of these sites have many benefits and are worth checking out. There’s also a popular app called Juxtapost.

Aside from food lovers, Pinterest isn’t for everyone. Moreover, monetization is not available in some countries, and user-generated content is uneven. As a result, using the appropriate words is important. In addition, Pinterest isn’t very user-friendly for beginners. You might want to invest in a few apps that work with your smartphone or tablet. If you can’t decide on any of these options, check out some of the other social media sites that are similar.

Another popular alternative to Pinterest is FoodGawker. This site is devoted to food lovers, and offers recipes, and other related content. While the concept of both sites is similar, each site has its own advantages and disadvantages. However, many users find Pinterest to be the most appealing social media platform for their interests. In addition to this, some people find FoodGawker to be the best alternative to Pinterest in terms of food-related content.

Some Pinterest social media alternatives are not suitable for everyone. While MANteresting is dedicated to food lovers, DartItUp is geared toward college-minded sports fans. Other alternatives include Pearltrees, which is similar to Pinterest but has a different concept. Its members can bookmark and share content. Its concept is centered around the concepts of trees and pearls. The user can even follow their favorite tree or pearl to stay updated on its content.

Although Pinterest is the best-known social networking site, it doesn’t offer instant gratification. It requires a lot of time and effort to understand, and ads are expensive. Additionally, Pinterest isn’t ideal for beginners. For those who want to use the site, it’s best to learn how to create a profile and use the platform’s search engine. The website has been updated continuously, so it’s not always easy to find what you’re looking for.

Besides being a great social networking site, there are many alternatives to Pinterest. Some of them are better for certain purposes. The main reason why Pinterest is so popular is that it has a limited number of categories and restrictions. The website is best for people who enjoy art and design. If you’re interested in a particular niche, you can choose one of these sites. The site has a huge database of artists and designers who can share and sell their works.

Technology – What Is An Iterative Approach In Software Development?


What is an iterative development approach? This software development method combines an iterative design process and an incremental build model. It can be applied to any type of software project. Iterative development approaches are also known as agile development. These methodologies are generally used for smaller projects. In many cases, a team of developers can produce a complete version of the product within a year. This approach is ideal for small and medium-sized organizations.

The iterative software development model allows rapid adaptation to changes in user needs. It enables the rapid change of code structure and implementations with minimum cost and time. If a change is not beneficial, the previous iteration can be rolled back. Iterative development is a proven technique that is gaining momentum in software development. This approach has several advantages. It is flexible and adaptable, allowing companies to rapidly respond to changing client needs.

Iterative development allows for rapid adaptation to changing requirements. This approach is especially useful for small companies, as it can make fundamental changes to the architecture and implementation without incurring too much cost or time. The team can also roll back to the previous iteration if the change is too detrimental. In addition, the process ensures that the customer will have the product that they want. The customer will be satisfied with the end product with the iterative approach.

When developing a large software, you must develop an efficient, high-quality product. This is important if your product is large and requires significant change to achieve success. With an iterative approach, you can make incremental changes in the development process without having to rewrite the entire software. As a result, iterative development ensures that you deliver the best quality and most efficient solution possible.

With an iterative development approach, the team can make changes to the software rapidly, allowing it to evolve as the business needs change. With iterative development, iterative improvements are more likely to be made, and the system will be more effective in the long run. The process can also be more cost-effective if you deliver a complex and complicated product. The best part about this approach is that it is incredibly easy to learn.

One of the main advantages of an iterative development approach is that it provides rapid adaptation to changing needs. Iterative development allows you to make changes in the code structure or implementation. You can make fundamental changes without incurring high costs or affecting the original design. You can also change the design of the application as you go along. In this way, you can be certain that the product will be able to meet the market needs of your customers.

There are several disadvantages to iterative development. It may require more intensive project management. The system architecture might not be well-defined and may become a constraint. Finding highly skilled people for risk analysis and software design is also time-consuming. However, in the case of a game app, an iterative approach will give you a complete and workable product to test out in the real world.

Using an iterative development approach will allow you to make fundamental changes to your software in a short amount of time. Iterative development will allow you to make changes to your software architecture and the overall design of the product. This is why this process is so popular with game developers and is often recommended by other organizations. Iterative development will improve the quality of your game, while a traditional one will delay the release date.

The iterative development approach is the most effective way of software development. It allows you to make fundamental changes quickly, with a minimal impact on the quality of the finished product. During this process, iterative development will result in a more useful and less costly deliverable. In many cases, iterative development will lead to a better product than a waterfall-style approach.

Technology – Alternative Browsers For Chrome


Many of the more popular browsers, namely Microsoft’s Internet Explorer and Mozilla Firefox, are not considered “open source” browsers. This is because they are not developed by or developed for the community. Their code is not released under an Open Source license but instead is released under a Commercial License. These licenses can be a bit restrictive, especially in terms of the license requirements. In this article, I will explain what Commercial Licenses are and how they affect non-Microsoft browsers.

A Commercial License is a type of royalty that allows the manufacturer to charge a fee for use in the developer’s program. While this is the most common licensing arrangement for web browsers, not all of them employ this mechanism. The most common example is Sun’s OpenOffice suite, designed as an open-source project but heavily commercialized. This is similar to Microsoft’s Office Suite, which is also based on an Open Source project. Microsoft’s ActiveX and Adobe Flash are also based on Commercial License programs.

There are two main limitations of Commercial Licenses when it comes to non-Microsoft browsers. First, they can be expensive. Microsoft has designed its own engine from scratch and has no competitors to support it. Due to its proprietary nature, this engine cannot be shared with any other browser and must always be included with Microsoft’s Internet Explorer. In short, if you want a non-Microsoft browser, you’re going to have to spend more money – though it is worth it.

Second, many of the Commercial Licenses include clauses that limit the browser’s distribution to specific parties. These are generally the carriers and manufacturers of Microsoft’s products and restrict browser distribution. Some clauses are so limiting that many organizations, such as universities and schools, choose to implement their own browsers instead of Microsoft. This is not recommended. The Internet is an open platform, and everyone is free to implement any technology they deem appropriate.

The WebKit-based Browser from Apple is one example. Apple’s Safari is based on the same codebase as WebKit and is not a fork of WebKit. Neither is it an alternative and in fact, it is not even really a browser at all. The primary difference is that Safari uses WebKit for most elements, such as web navigation. It also includes a new WebKit-based key-board layout much like what you’d see on the Mac OS X platform.

Open Source-based browsers, such as Mozilla Firefox, are not based on any license agreement but instead are derivatives of the Mozilla codebase. This means that the code is available for anyone to change and customize, while the licensing terms are much more permissive. Although this type of browser doesn’t come pre-installed with Microsoft, it can still be used with Microsoft applications if you buy a license for it. However, it has its drawbacks, such as lacking many customization options available with commercial non-Microsoft browsers.

Opera is also a popular browser and is similar to Safari in many ways. It is a fork of the Linux operating system. While the commercial version has many advantages, such as the ability to use most of the Microsoft Office software pre-installed, Opera is often seen as lacking some of the features available with Microsoft. For instance, it lacks the password manager and some of the other Microsoft-related tools. However, the software does have an excellent user interface and is the preferred browsing application for many developers and designers.

Finally, there are third-party browsers available for Chrome. These browsers are less expensive than Microsoft-based browsers and have many of the same features available with Microsoft browsers.  Some of the Opera features, like the password manager, can also be found in a third-party browser. This gives users of all operating systems more freedom to choose which browser they want to use for their surfing needs.

Technology – Denodo ODBC And JDBC Driver Virtual DataPort (VDP) Engine Compatibility?


Recently, while patching a Denodo environment, the question arose as to whether an older ODBC or JDBC driver can be used against a newer patched environment. It is described in the first paragraph of the denodo documentation, the directionality of the compatibility can be overlooked easily.

Can An Older ODBC Or JDBC Driver Be Used Against A Newer Past Environment?

The short answer is yes.  Denodo permits backward compatibility of older drivers with newer versions. Even across major versions for denodo version 7 and 8.

ODBC and JDBC driver Compatibility

The older ODBC and JDBC drivers can be of an update that is an older version (patch or major version) than the update installed on the server.

However, as is clearly stated in the documentation, you cannot use a newer driver against an older version of Denodo. This goes for denodo patch versions as well as denodo major versions. Connecting a Virtual DataPort server using an updated newer ODBC or JDBC on the Virtual DataPort (VDP) Engine server. This will not be supported, and it may lead to unexpected errors.

Technology – An Introduction to SQL Server Express


If you use SQL, several options are open to you, from the Enterprise editions down to SQL Server Express, a free version of Microsoft’s main RDBMS (Relational Database Management System), SQL Server. SQL Server is used to store information and access other information from multiple other databases. Server Express Edition is packed with features, such as reporting tools, business intelligence, advanced analytics, and so on.

SQL Server Express 2019 is the basic version of SQL Server, a database engine that can be deployed to a server, or you can embed it into an application. It is free and ideal for building desktops and small server applications driven by data. It is ideal for independent software developers, vendors, and those building smaller client apps.

The Benefits

SQL Server Express offers plenty of benefits, including:

  • Automated Patching – allows you to schedule windows to install important updates, to SQL Server and Windows automatically
  • Automated Backup – take regular backups of your database
  • Connectivity Restrictions – when you install Express on an Image Gallery-created Server VM installation, there are three options to restrict connectivity – Local (in the VM), Private (in a Virtual Network), and Public (via the Internet)
  • Server-Side Encryption/Disk Encryption – Server-side encryption is encryption-at-rest, and disk encryption encrypts data disks and the OS using Azure Key Vault
  • RBAC Built-In Roles – Role-Based Access Control roles work with your own custom rules and can be used to control Azure resource access.

The Limitations

However, SQL Express also has its limitations:

  • The database engine can only use a maximum of 1 GB of memory
  • The database size is limited to 10 GB
  • A maximum of 1 MB buffer cache
  • The CPU is limited to four cores or one socket, whichever is the least. However, there are no limits to SQL connections.

Getting Around the Limitations

Although your maximum database size is limited to 10 GB (Log Files are not included in this), you are not limited to how many databases you can have in an instance. In that way, a developer could get around that limit by having several interconnected databases. However, you are still limited to 1 GB of memory, so using the benefit of having several databases to get around the limitation could be wiped out by slow-running applications.

You could have up to 50 instances on a server, though, and each one has a limit of 1 GB memory, but the application’s development cost could end up being far more than purchasing a standard SQL license.

So, in a nutshell, while there are ways around the limits, they don’t always pay off.

SQL Server Express Versions

SQL Server Express comes in several versions:

  • SQL Server Express With Tools – this version has the SQL Server Database, and all the tools need for managing SQL instances, such as SQL Azure, LocalDB, and SQL Server Express
  • SQL Server Management Studio – this version contains the tools needed for managing SQL Server Instances, such as SQL Azure, SQL Express, and Local DB, but it doesn’t have SQL Server
  • SQL Server Express LocalDB –  if you need SQL Server Express embedded into an application, this version is the one for you. It is a lite Express version with all the Express features, but it runs in User Mode and installs fast with zero-configuration
  • SQL Server Express With Advanced Series – this version offers the full SQL Server Express experience. It offers the database engine, the management tools, Full-Text Search, Reporting Services, Express tools, and everything else that SQL Server Express has.

What SQL Server Express 2019 is Used For and Who Uses it

Typically, SQL Server Express is used for development purposes and to build small-scale applications. It suits the development of mobile web and desktop applications and, while there are some limitations, it offers the same databases as the paid versions, and it has many of the same features.

MSDE was the first SQL Server Data Engine from Microsoft, which was called Microsoft Desktop Engine. SQL Server Express grew when Microsoft wanted to build a Microsoft Access alternative to provide software vendors and developers with a path to the premium versions of SQL Server Enterprise and Standard.  

It is typically used to develop small business applications – web apps, desktop apps, or mobile apps. It doesn’t have all the features the premium versions have. Still, most small businesses don’t have the luxury of using a DBA (SQL Server database administrator), and they often don’t have access to developers who use DBAs either.

Lots of independent developers embed Server Express into the software, given that distribution is free. Microsoft has even gone down the road of creating SQL Server Express LocalDB. This lite version offers independent software vendors and developers an easier way of running the Server in-process in the applications and not separately. SQL Server Express is also considered a great starting point for those looking to learn about SQL Server.

Downloading SQL Server Express Edition 2019

SQL Server Express Edition 2019 is pretty easy to download, and you get it from the official Microsoft Website.

Once you have downloaded it onto your computer, follow the steps below to install it and set it up:

Step One

  • Right-click on the installation file, SQL2019-SSEI-Expr.exe.
  • Click on Open to get the installation process started – ensure that the user who is logged on has the rights needed to install software on the system. If not, there will be issues during the installation and setup.

Step Two

  • Now you need to choose which type of installation you need. There are three:
  • Basic – installs the database engine using the default configuration setup
  • Custom – this takes you through the installation wizard and lets you decide which parts to install. This is a detailed installation and takes longer than the basic installation
  • Download Media – this option allows you to download the Server files and install them when you want on whatever computer you want.
  • Choose the Custom installation – while the Basic is the easiest one, takes less time, and you don’t need to worry about the configuration as it is all done for you, the custom version allows you to configure everything how you want it.

Step Three

  • Now you have a choice of three package installation types:
  • Express Core – at 248 MB, this only installs the SQL Server Engine
  • Express Advanced – at 789 MB, this installs the SQL Server Engine, Full-Text Service, and the Reporting Services features
  • LocalDB – at 53 MB, this is the smallest package and is a lite version of the full Express Edition, offering all the features but running in user mode.

Step Four

  • Click on Download and choose the path to install Server Express to – C:\SQL2019
  • Click on Install and leave Server Express to install – you will see a time indicator on your screen, and how long it takes will depend on your system and internet speed.

Step Five

  • Once the installation is complete, you will see the SQL Server Installation Center screen. This screen offers a few choices:
  • New SQL Server Stand-Alone Installation or Add Features to Existing Installation
  • Install SQL Server Reporting Services
  • Install SQL Server Management Tools
  • Install SQL Server Data Tools
  • Upgrade From a Previous Version of SQL Server
  • We will choose the first option – click on it and accept the License Terms

Step Six

  • Click on Next, and you will see the Global Rules Screen, where the setup is checked against your system configuration
  • Click on Next, and the Product Updates screen appears. This screen looks for updates to the setup. Also, if you have no internet connection, you can disable the option to Include SQL Server Product Updates
  • Click on Next, and the Install Rules screen appears. This screen will check for any issues that might have happened during the installation. Click on Next

Step Seven

  • Click on Next, and the Feature Selection screen appears
  • Here, we choose which features are to be installed. As you will see, all options are enabled, so disable these:
  • Machine Learning Services and Language Extensions
  • Full-Text and Semantic Extractions for Search
  • PolyBase Query Service for External Data
  • LocalDB
  • Near the bottom of the page, you will see the Instance Root Directory option. Set the path as C:\Program Files\Microsoft SQL Server\

Step Eight

  • Click Next, and you will see the Server Configuration screen
  • Here, we will set the Server Database Engine startup type – in this case, leave the default options as they are
  • Click on the Collation tab to customize the SQL Server collation option
  • Click Database Engine Configuration to specify the Server authentication mode – there are two options:
  • Windows Authentication Mode – Windows will control the SQL logins – this is the best practice mode
  • Mixed Mode – Windows and SQL Server authentication can access the SQL Server.
  • Click on Mixed Mode, and the SQL Server login password can be set, along with a Windows login. Click on the Add Current User button to add the current user

Step Nine

  • Click on the Data Directories tab and set the following;
  • Data Root Directory – C:\Program Files\Microsoft SQL Server\
  • User Database Directory – C:\Program fees\Microsoft SQL Server\MSSQL.15.SQLEXPRESS\MSSQL\Data
  • User Database Log Directory – C:\Program fees\Microsoft SQL Server\MSSQL.15.SQLEXPRESS\MSSQL\Data
  • Backup Directory – C:\Program fees\Microsoft SQL Server\MSSQL.15.SQLEXPRESS\MSSQL\Backup

Step Ten

  • Click the TempDB tab and set the size and number of tempdb files – keep the default settings and click Next
  • Now you will see the Installation Progress screen where you can monitor the installation
  • When done, you will see the Complete Screen, telling you the installation was successful.

Frequently Asked Questions

Microsoft SQL Server Express Edition  2019 is popular, and the following frequently asked questions and answers will tell you everything else you need to know about it.

Can More than One Person Use Applications That Utilize SQL Server Express?

If the application is a desktop application, it can connect to all Express databases stored on other computers. However, you should remember that all applications are different, and not all are designed to be used by multiple people. Those designed for single-person use will not offer any options for changing the database location.

Where it is possible to share the database, the SQL Server Express Database must be stored in a secure, robust location, always be backed up, and available whenever needed. At one time, that location would have been a physical server located on the business premises but, these days, more and more businesses are opting for cloud-based storage options.

Can I Use SQL Server Express in Production Environments?

Yes, you can. In fact, some of the more popular CRM or accounting applications include Server Express. Some would tell you not to use it in a production environment, mostly because of the risks of surpassing your 10 GB data limit. However, provided you monitor this limit carefully, SWL Server Express Edition can easily be used in production environments.

Is SQL Server Express Edition Scalable?

There is a good reason why Microsoft allows you to download SQL Server Express Edition for free. It’s because, if it proves too small for your needs, at some point, you can upgrade to the premium SQL Server Standard version. While the Express Edition is limited and you are likely to outgrow it at some point, transferring your database over to the Standard version when the time comes is easy. Really, the Express version is just a scaled-down version of Standard. Any development you do on it is fully compatible with any other Edition of SQL Server and can easily be deployed.

Can I Use SQL Server Express in the Cloud?

Cloud computing is being adopted by more and more businesses and their applications. These days, many are now built in the cloud as web or mobile apps. However, when it comes to desktop applications, it is a slightly different story, as these need to be near the SQL Server Express Database to work properly. Suppose you host the database in the cloud but leave the application on the desktop. In that case, you are likely to experience poor performance, and you may even find your databases becoming corrupted.

You can get around this issue by running your application in the cloud, too, and this is easy using a hosted desktop (a hosted remote desktop service), which used to be known as a terminal service. In this case, the database and application reside on servers in the data center provided by the host and are remotely controlled by the users. As far as the user is concerned, it won’t look or feel any different from running on their own computer.

What Do I Get With SQL Server Express?

The premium SQL Server editions contain many features that you can also find in the free SQL Server Express Edition. Aside from the database engine, you also get:

Plus, the Express licensing allows you to bundles SQL Server Express with third-party applications.

What Isn’t Included?

There are a few things you don’t get in the Express edition compared to SQL Server Standard. For a start, Express edition has limits not found in the premium editions:

  • Each relational database can be no larger than 10 GB, but log files are not included as there are no limits on these
  • The database engine is limited to just 1 GB of memory
  • The database engine is also restricted to one CPU socket or four CPU cores, whichever is the lower of the two.
  • All the SQL Server Express Edition components must be installed on a single server
  • SQL Server Agent is not included – admins use this for automating tasks such as database replication, backups, monitoring, scheduling, and permissions.
  • Availability Groups
  • Backup Compression
  • Database Mirrors limited to Witness Only
  • Encrypted Backup
  • Failover Clusters
  • Fast recovery
  • Hot add memory and CPU
  • Hybrid Backup to Windows Azure
  • Log Shipping
  • Mirrored backups
  • Online Index create and rebuild
  • Online Page and file restore
  • Online schema change
  • Resumable online index rebuilds

Where Do I Find the SQL Server Express Edition Documentation?

You can find the relevant documentation at and are urged to make good use of it. Refer to the documentation whenever you don’t understand something or want to learn how to do something new.

Microsoft SQL Server Express Edition 2019 is worth considering for small businesses, as it gives you a good starting point. As your business grows, you can upgrade to the premium versions without having to worry about learning a new system – you already know the basics, and your databases will transfer seamlessly over.

Business – What New In LibreOffice 7.2


What is in the new release of LibreOffice? Many of the most desired improvements were seen with the improvements to Word and the other office applications. With the Windows operating system that has been used by most people for the majority of their computing needs, the current release of the software has a lot to prove. Most users of this application have come to rely on it as their primary office suite and are quite happy with the current features and improvements. The improvements and additions made to this software are truly impressive.

Users may enjoy new features like:

  • a new object inspector for developers
  • full background fills in Writer
  • multiple columns in text boxes
  • new templates for the Impress presentation graphics application, and
  • user interface improvements.

The biggest announcement about the new version of LibreOffice is that the document format has been completely rebuilt. This means that document searching is now faster, the program will recognize when you save a document, and the entire document can be indexed easily. There are so many improvements in the Document Viewer that will allow your document viewing to be more fluid. This feature works very nicely for creating PDFs, and there are many document viewing functions available in the application.

There is a brand new feature that allows business users to view scanned copies of any documents that they might have previously saved on PDF files. With earlier versions of the application, the only way to do this was to save the document directly to a PDF file or to an external database. This feature is extremely useful for anyone who needs to access such documents regularly. The PDF feature is also useful for students who often spend long periods producing their thesis and other documents.

There are many improvements to the scanning function, which allows you to preview documents that have already been scanned. You can view the whole document or just parts, and you can zoom in or out using the mouse wheel. In addition to being able to preview the scanned file, there are many other features available. You can add text, rotate, and zoom in on all the features available on the screen. The improved zoom functions make it easy to add some extra information to the scanned document.

The Document Look feature works similar to the previous versions of the application, where you could click on the title of the image and then choose the option you wanted to edit. This feature still works in the new version, but options are now in the main menu to skew, stretch, and rotate the image. This feature works very well with the PDF feature and allows you to edit and crop the document differently. This is especially useful when you want to change the shape of a document.

There is also a new feature that allows you to edit your PowerPoint presentations. It looks very much like the PowerPoint viewer of the previous version but with some added features. You can go into the preferences and under the settings tab, there is a link for selecting an appropriate viewer. The new feature works very well with PDF and HTML documents and allows you to add text, images, and clip arts. This is a very helpful feature, especially if you are creating a presentation for a company and want to show a few mock documents. You can add text, images, and videos and change the look with the right controls.

The new feature allows you to search documents using keywords. It works very well with the PDF feature, as you can search according to keywords or subject matter. The other features do the same thing. You can search according to tags, subjects, dates, modified dates, sizes, widths, and positions, and you will get the matching document in the list.

Overall, the improvements introduced in LibreOffice 7.2 can be seen in every part of the application. You can scan and save your documents in a better way with this version. The enhanced zoom functions, document look-ups, document searches, and options for sharing your work make it a great choice for your workplace.

Business – LibreOffice Writer Basics


This LibreOffice Writer beginner’s tutorial will show you the basics of the application, which is actually a spreadsheet application. It has been developed by Open Office, a free suite of office productivity software, which also includes Calc+Wysiwyg, and Placewinds. This free application was released in April 2021 and has gained much popularity among users due to its WYSIWYG user friendly interface.

To start with the usage, you will have to start an editing session. In this application there are two possible views available in which the first view is the standard one where you can drag and drop any text from the text box. The second view is the ribbon view which allows you to move and create text in the workspace while dragging and dropping items from the tool menu. To edit the current selection simply highlight it and click on the Properties button. You will find various options in this window like font, style, color, size, location, justification, align, justification, and justification. There is also a format option available which lets you choose the desired character when you enter the text in the text box.

There are two ways you can copy text from the document. You can use the Copy As option in the General tab of the Editor properties. The first cell in the Workplane panel will be automatically replaced by the destination location, where the copied text will be placed in this option. Another option is to use the Clip Art tool in the main menu. Select the graphic that you want to use as copy area and then highlight it and pressing the copy option.

The next step in the LibreOffice Writer Tutorial is how to edit the text. The toolbar is located at the top right corner of the screen. If you right click on the toolbar then an editor will open in the designated area. You will find the following options in the editor:

Use the Edit selection mode by holding down the Alt key while selecting the text you want to place in the toolbar. Now you can move the selection region of the toolbar to different areas. Another useful option is the Auto option. With this option the toolbar will display automatically selected text when you double click on it. This feature is especially useful when you have a lot of text or a long selection.

The Format option is used for changing the value of the selection. With the Format function, you can easily change the formatting of the selection. All you need to do is select the desired action and then select the format option. The Format toolbar has general tools and more advanced ones under the Insert tab. To create a formatted selection, click on the Format button and then select the desired action.

There are many more features that are available since version 1.4. For a beginner the main limitation of this text editor is that you cannot drag selections with the mouse. You need to use the keyboard focus instead. One thing you must keep in mind is that when editing a selection, the result will be printed not only to the screen but also to the console. This is a problem for copy and paste functions.

However, it is not the fault of the software. It is available since long time and its functionality has never changed. The developers of this text processing software has added more features to keep up with the competition.

For example the Replace function allows you to replace text in a selected text area. When you use this function, the text you want to replace will be replaced with the equivalent text in the current document. The Replace function is great to use when you have more than one form of input to process. For example: you have a list of forms and you want to change the values of some of them by entering their names in the Replace function.

There is also the Replace heading option available since version 1.4. Here you can use the keyboard focus in order to create a selection of a specific heading or group of headings. The Use Highlight option is another great tool available since 1.4. Here you can highlight the texts in your document for easy reading.

The other tools available since version 1.4 include the Instant Fix tool and the Replace Exercise. These two tools allow you to quickly fix common errors that occur when you are editing text. This is a great way to correct mistakes in spelling and grammar using high quality software.

Technology – The Difference Between Float Vs. Double Data Types


It would be incorrect to say that floating-point numbers should never be used as an SQL data type for arithmetic. I will stick to double-precision floating-point data types for SQL Server that are suitable for my requirements.

The double-precision floating-point data type is ideal for modeling weather systems or displaying trajectories but not for the type of calculations the average organization may use in the database. The biggest difference is in the accuracy when creating the database. You need to analyze the data types and fields to ensure no errors and insert the data values for maximum accuracy. If there is a large deviation, the data will not be processed during the calculation. If you detect incorrect use of the data type with double precision, you can switch to a suitable decimal or number type.

What are the differences between numeric, float, and decimal data types, and should they be used in which situations?

  • Approximate numeric data types do not store the exact values specified for many numbers; they store an extremely close approximation of the value
  • Avoid using float or real columns in WHERE clause search conditions, especially the = and <> operators

For example, suppose the data that the report has received is summarized at the end of the month or end of the year. In that case, the decimal data for calculation becomes integer data and is added to the summary table.

In SQL Server, the data type float _ n corresponds to the ISO standard with a value from n = 1 to 53. The floating-point data is approximated not by the data type’s value but by the range of what can be represented. Both float- and float-related numeric SQL types consist of a significant numeric value and an exponent, a signed integer that indicates the size of the numeric value.

And float-related numeric SQL data types are precise positive integers that define the number of significant digits and exponents of a base number. This type of data representation is called floating-point representation. A float is an approximate number, meaning that not all values can be displayed in the data type range because it is a rounded value.

You can’t blame people for using a data type called Money to store the money supply. In SQL Server, decimal, number, Money, and SmallMoney data types have a decimal place to store values. Precision means the total number of digits after the decimal point.

From a mathematical point of view, there is a natural tendency to use floats. People who use float spend their lives rounding up values and solving problems that shouldn’t exist. As I mentioned earlier, there are places where it makes sense to hover above the real, but these are for scientific calculations, not business calculations.

SmallMoney (2144783647, 4 bytes) We can use this data type for Money- or currency values. The double type can be used as a data type with real values for dealing with Money.

Type Description Memory bits Integer 0 1 null TinyInt allows integers 0 to 255 1 bytes TinyInt allows integers 32767 2 bytes Int allows integers 2147483647 4 bytes BigInt allows integers 9223372036854775807 8 bytes Decimal P is a precisely scaled number. The parameter p specifies the maximum total number of digits stored to the left or right of the decimal point. The data type low and upper range storage observations Real 340E 38 4 Bytes We can use float924 as an ISO synonym for real.

In MariaDB, the number of seconds has elapsed since the beginning of the 1970s (01-01) with a decimal accuracy of 6 digits (0 is the default). The same range of precision is the SQL Server type range (bytes) MariaDB type range size (bytes) Precision notes Date 0001 01-01-99.99 12: 31: 3 They cover the same range: Date 0.001-03-01 9.99912: 31 8: 0: 3 Round DateTime 0.01 0.1-02.9999 12: 31 8 0: 6 In MariaDB the value is near impossible to specify (see below). We can insert a value that requires fewer bits than that assigned to the null-bit pad on the left.

A binary string is a sequence of octets, not a character set, and the associated sorting is described by the binary data type descriptor. Decimal (p) is the exact numerical precision (p scale (n)) of a decimal number that is any number with a decimal point. A Boolean data type consists of different truth values (true, false, and boolean), and it supports unknown truth values, zeroes, and forbidden (not zero) constraints.

This syntax was deprecated in MySQL and will be removed in future versions of MySQL: float (p) A floating-point number. MySQL uses the p-value to specify whether to use a float or a double due to the data type.

Creating data types in PostgreSQL is done with the create-type command. For example, the following commonly used data types are organized into categories with a brief description of the value range and memory size. The native data type is the text data type, the numeric data type, and the date/time Boolean data type.

To understand what floating-point SQL is and what numerical data types are, you need to study computer science a little. Floating-point arithmetic was developed when saving memory was a priority and was used as a versatile method for calculating large numbers. The SQL Prompt Code Analysis Rule (BP023) warns you when using Floating over Real data types. It introduces significant inaccuracies into the type of calculations that many companies do with their SQL Server data.

The difference between a float and a p is that a real float is binary (not decimal) and has an accuracy equal to or greater than the defined value.

The reason for this difference is that the SQL standard specifies a default from 0 to D. Still, the implementation is free to choose a default M. This means that an operation of this type will result in a result different from the result it would produce for MariaDB type if you use enough decimal places. It is important to remember that numerical SQL data types sacrifice precision ranges to approximate the names.

Technology – What Is The Data Fabric Approach?


What is The data fabric, and how does it automating discovery, creation, and ingestion help organizations? Data-fabric tools, which can be appliances, devices, or software, allow users to quickly, easily, and securely access and manage large amounts of data. Automating the discovery, creation, and ingestion, big data Fabric accelerates real-time insights from operational data silos, reducing IT expenses. While this is already a buzzword amongst business architects and data enthusiasts, what exactly does the introduction of data-fabric tools mean for you?

In an enterprise environment, managing information requires integrating diverse systems, applications, storage, and servers. This means that finding out what consumers need is often difficult without the aid of industry-wide data-analyzing, data-warehousing, and application discovery methods. Traditional IT policies such as traditional computing, client-server, or workstation-based architectures are no longer enough to satisfy the needs of companies within an ever-changing marketplace.

Companies in the information age no longer prefer to work in silos. Organizations now face the necessity of automating the management of their data sources. This entails the management of a large number of moving parts -not just one. Therefore, a data management system needs to be very flexible and customizable to cope with the fast changes taking place in information technology. The traditional IT policies may not keep up with the pace of change; thus, some IT departments might be forced to look for alternative solutions such as a data fabric approach. A data-fabric approach automates the entire data management process, from discovery to ingestion.

Data fabrics are applications that enable organizations to leverage the full power of IT through a common fabric. With this approach, real-time business decisions can be made, enabling the tactical and strategic deployment of applications. Imagine the possibilities: using data management systems to determine which applications should run on the main network or which ones should be placed on a secondary network. With real-time capabilities, these applications can also be able to use different storage configurations – meaning, real-time data can be accessed from any location, even while someone is sleeping. And because the applications running on the fabric are designed to be highly available and fault-tolerant, any failure within the same fabric will not affect other services or applications. This results in a streamlined and reliable infrastructure.

There are two types of data fabrics: infrastructure-based and application-based. Infrastructure-based data fabrics are used in large enterprises where multiple applications need to be implemented and managed simultaneously. For example, the IT department may decide to use an enterprise data lake (EDL) to use many file servers. Enterprise data lakes allow users to access data directly from the source rather than log on to a file server every time they need information. File servers are more susceptible to viruses, so IT administrators may find it beneficial to deploy their EDLS over the file server. This scenario exemplifies the importance of data preparation and recovery.

Application-wise, data preparation can be done by employing the smart enterprise graph (SEM). A smart enterprise graph is one in which all data sources (read/write resources) are automatically classified based on capacity and relevance and then mapped in a manner that intelligently allows organizations to rapidly use the available resources. Organizations can decide how to best utilize their data sources based on key performance indicators (KPIs), allowing them to make the most of their available resources. This SEM concept has been implemented in many different contexts, including online retailing, customer relationship management (CRM), human resources, manufacturing, and financial industries.

Data automation also provides the basis for big data fabric, which refers to collecting, preparing, analyzing, and distributing big data on a managed infrastructure. In a big data fabric environment, data is processed more thoroughly and more quickly than ingesting on a smaller scale. Enterprises are able to reduce costs, shorten cycle times, and maximize operational efficiencies by automating ingesting, processing, and deployment on a managed infrastructure. Enterprises may also discover ways to leverage their existing network and storage systems to improve data processing speed and storage density.

When talking about what is data fabric approach, it’s easy to overstate its value. However, in the right environments and with the right intelligence, data fabrics can substantially improve operational efficiencies, reduce maintenance costs, and even create new business opportunities. Any company looking to expand their business should consider deploying a data fabric approach as soon as possible. In the meantime, any IT department looking to streamline its operations and decrease workloads should investigate the possibility of implementing a data fabrics approach.

Technology – The Advantages of Using Microsoft SQL Server Integration Services


Microsoft SQL Server Integration Services (SSIS) is designed to combine the features of SQL Server with components of Enterprise Management System (EMMS) so that they can work together for enterprise solutions. Its core area of expertise is bulk/batched data delivery. As a SQL Server collection member, Integration Services is a logical solution to common organizational needs and current market trends, particularly those expressed by previously installed SQL Server users. It extends SSIS functionality, such as data extraction from external sources, data transformations, data maintenance, and data management. It also helps to convert data from one server into another.

There are several ways to use SSIS. External data sources may be data obtained from an outside source, such as a third-party application, or data obtained from an on-site database, such as a company’s own system. These external sources may contain transformations, including automatic updates, or specific requests, such as viewing certain data sources. There is also the possibility of data integration, in which different sets of data sources may be integrated into SSIS. Integration Services is useful for developing, deploying, and maintaining customer databases and other information sources.

The advantage of integrating SSIS with other vendors’ products is that it allows information to be made available within the organization and outside the organization. In other words, vendors can sell to internal users as well as external customers. Integration Services is usually sold as part of Microsoft SQL Server solutions. However, some companies may develop their own SSIS interfaces and build the entire communication layer independently.

There are two major advantages of using SSIS. The first is great support for telecommunication companies and enterprises that need to process a huge amount of information quickly and efficiently. Telecommunication companies use SSI to interface with other modules such as Microsoft Office applications, Sharepoint, and more. Another advantage of SSI is that integration provides access to all of the capabilities that a particular program or server has, such as data integration with Microsoft Visual Basic and JavaScript and the program’s full functionality or server. SSI is commonly used for web applications, particularly in sites that have to process large amounts of data quickly and efficiently.

There are a few disadvantages of using SSI, however. SSI is quite slow when compared to VBA and another object-oriented programming (OOP) methods. SSI also has some disadvantages in data quality, and the SSI interface can be difficult to use if one does not know how to code in the programming language. SSI is also limited in the number of programs and applications that can be integrated into one installation of SSI.

SSI is not only less flexible than VBA but can also be slower when compared to the traditional VBA script programs, as well. SSI can use a program or server with an SSI interface. Still, not all programs and servers that support SSI will provide an interactive command line for integration with a Microsoft SQL Server Integration Services database. In some cases, an interactive command line is necessary for SSI to use the DTS file necessary to process the data from an in-house database. SSI cannot connect to SSO independently but can use an in-house or external SSI file as a starting point for a connect and bind scenario.

For SSI to work effectively in a team-based development environment, the developer must understand and be familiar with the program. SSI has been designed with several different developer topologies and languages to write code and have it run in a timely manner while keeping track of files that might not be included with the program. A team-based development environment should be defined as a group effort where regular communication between team members and corporate databases can help this process along. SSI was designed to provide developers with the flexibility and control they need to maintain these relationships.

SSI can provide several advantages over VBA, including support for data structures in various programming languages and formats. This type of integration can save time for a business and is very cost-effective. SSI also provides several different programming interfaces and is flexible enough to use in any environment. If your company needs to use SSI, you must take the time to learn how to integrate it with your company’s database to ensure that the data structures used are compatible and effective for your application.

Technology – Can SQL Server Run On Linux?


Microsoft SQL Server provides organizations with industry-leading data capabilities, enhanced security, performance, and total cost of ownership. Unfortunately, up until 2017, SQL Server could only run on a windows ecosystem.

This was a huge pain point for many SQL server customers who preferred the Linux system over Windows for performance, security, and manageability. They had to run a separate MS Windows system just to support the SQL server! Not running MSQL Server on a Linux ecosystem became a friction point for many of these businesses.

Looking forward, can SQL server run on Linux? Yes. It’s now possible to run MSSQL Server on a Linux system. In 2017, Microsoft released SQL Server 2017, which could now run on Windows, Linux, and Docker containers. This was an exciting move by Microsoft, which seemed more focused on bringing its tools to wherever its users were.

Running SQL Server On Your Favorite Platform

MSSQL Server users can now install the relational database engine on an enterprise Linux ecosystem. Some of the Linux distributions which support SQL Server include:

  • Red Hat Enterprise 7.3+,
  • SUSE Enterprise V12 SP2+,
  • Ubuntu 16.04+
  • Docker (1.8+)

This cross-platform integration was made possible by a cool technology known as the SQL Platform Abstraction Layer (SQLPAL). Ideally, the Platform Abstraction Layer (PAL) created a more secure virtual OS layer that allowed the SQL Server to run efficiently on a Linux system without compromising its functionality.

This seamless cross-platform integration meant that Microsoft developers could maintain all vital SQL Server functions without the need to port the tens of millions of lines of MSSQL Server’s code to Linux.

Why Should I Run SQL Server on Linux?

Wondering if you should run SQL Server on Linux? Here are a few benefits:

  • Reduced Operating Cost due to a seamless cross-platform licensing model
  • Enterprise-ready features
  • Enhanced SQL server performance on Linux
  • Faster installation and maintenance


It’s now possible and super-easy to run Microsoft SQL Server on a Linux system. Today, millions of organizations run SQL Server on Linux OS, which has cut the cost and time to run and maintain their relational database engine. In the end, the cross-platform MSSQL Server integration on a Linux ecosystem removes the barrier to entry for organizations that prefer Linux to Windows.

Technology – What Is SQLite?


SQLite is open source, free, and available for use in both on-site and off-site databases. SQLite is an embedded, file-based RDBMS to support local data storage for individual applications and devices.

SQLite Use Cases

SQLite’s RDBMS characteristics and very small footprint make SQLite a good fit for these Use Cases:

  • Internet Of Things (IoT) and embedded devices,
  • Low-to-medium traffic websites
  • Small Scale testing and internal development,
  • Data analysis using Tcl or Python, and
  • Small Scale education applications

Advantages Of SQLite

There are many benefits and advantages of SQLite. SQLite is very stable and has a long history of support for various operating systems. The fact that it runs the most widely used server processes for DMS makes it one of the most popular open-source databases available today.

As a result, there are many unique features and functions that provide you with several advantages over other packages. Some of the benefits of SQLite are the following:

  • SQLite is safe and secure, easy to learn and easy to use,
  • SQLite does not require a server to run,
  • SQLite can be ported to a wide variety of platforms,
  • SQLite supports multitasking,
  • SQLite is extensible,
  • SQLite has a single database storage capability,
  • SQLite adheres to the ACID, providing security against all forms of data corruption, and
  • SQLite can use any language with which you are comfortable.

Disadvantages Of SQLite

As with any software, there are also some disadvantages of SQLite:

  • SQLite has a very limited feature set and capacity,
  • SQLite lacks multi-user capabilities which are normally found in full-fledged RDBMS systems,
  • SQLite uses serialized write operations,
  • SQLite lacks a Database as a Service (DBaaS) offering from the major cloud providers.

If you are new to programming, I’d suggest looking into some of the different ways to learn about databases — no “one size fits all” approaches here. SQLite comes complete with a Graphical User Interface that gives you unprecedented control over how you work with your database. You can create, modify and delete documents right from your graphical user interface, and many other functions, like filters and joins, can also be accessed from the graphical user interface. Overall, the SQLite package provides a very powerful way to manage your information… so long as you use it in the proper way.

Technology – What Are The SQL Minus and Except Clauses


Structured Query Language (SQL) is the de-facto query language used in most database management systems (DBMS) such as Oracle and Microsoft SQL Server. This domain-specific language is used in programming to query and return the desired data from a database. We use SQL to write queries that declare what data to expect from a dataset without really indicating how to obtain it. We can also use SQL to update and delete information from a database.

Ideally, in a relational database management system, the database usually runs on the “back end” side of a server in its structured form. By itself, this data is hard to interpret. So, users often have programs on a client computer that help to manipulate that data using rows, columns, fields, and tables. These programs are designed to allow users to send SQL statements to the server. The server then processes these statements by filtering data from the enormous, complex databases and returns results to the user.

Each query begins with finding the data needed then refining it down into something that can be processed and understood easily. To do this, you must use an organized set of operations to get meaningful data from a dataset. This article will explore the Minus Vs except SQL clauses to help you write optimized queries that run fast across various DBMS.


The SQL EXCEPT clause is one of the most commonly used statements that work together with two SELECT statements to return unique rows from a dataset. The SQL EXCEPT combines two SELECT statements to return the row that is present in the first select statement and not in the second.

If you’ve noticed, most SQL clauses do the same thing represented in standard spoken language. For instance, exception literally means not included. SQL EXCEPT is also very similar to the same concept.

The EXCEPT statement returns the distinct row from the left input query that is not output by the right input query. I.e., Returns the resultant rows that appear in query_expression_1 and not in query_expression_2.

SQL EXCEPT Clause Example

Consider a simple situation where you have two tables, one with dog names and the other one with cat names.

Cats Data Set


| CatId | CatName |


| 1 | Boss |

| 2 | Scarlet |

| 3 | Fluffy |

| 4 | Fluffy |


Dogs Data Set


| DogId | DogName |


| 1 | Yelp |

| 2 | Woof |

| 3 | Boss |

| 4 | Boss |


Using the SQL Except statement, we can filter the dataset and return only the distinct rows from the left SELECT query that have not been returned by the SELECT query on the right side of the EXCEPT statement.

An example SQL syntax query would look like this:




In a typical scenario, a client program will send this query to the “back-end” server. This statement is then processed and only returns the values available in the “cats” dataset that don’t appear in the “dogs” dataset. When two rows are similar, as is the case with “fluffy,” only one row is returned. This is because the SQL query only returns distinct rows.

Here’s the result of the above query:


| CatName |


| Fluffy |

| Scarlet |

+————– +

Common SQL Except Rules
  • You must have the same number of columns in both queries
  • The column order must be the same in all queries
  • The column data types must be compatible with each other. The data types really don’t have to be the same, but they MUST be comparable through implicit conversion.
  • The EXCEPT statement returns all records from the 1st SELECT statement not available in the second SELECT statement
  • The EXCEPT operator in the SQL server is similar to the MINUS operator in Oracle.
  • MySQL does not support SQL Except clause. The workaround is to use the LEFT JOIN clause when using MySQL.


MINUS operator does the same thing as the EXCEPT clause. But unlike the EXCEPT clause, the MINUS operator is only supported by Limit number of databases:

Database NameMinusExcept
Amazon RedshiftNoYes
VQL (denodo)YesNo
IBM Db2NoYes
Microsoft SQL ServerNoYes
PostgreSQL No Yes
SOQL (salesforce)NoNo

The MINUS operator compares two queries and only returns the rows present in the first dataset but are not output by the second set. The result usually contains the distinct rows available in the left Select statement that aren’t included in the results of the right select statement.

Here is a typical MINUS syntax:

SELECT column_list_1 FROM T1


SELECT column_list_2 FROM T2;

Common Oracle Minus Operator Rules

For MINUS operator to work, the dataset must conform with rules similar to those of SQL EXCEPT clause:

  • The data type of corresponding columns must be similar (Either Numeric or Character)
  • The order and number of columns must be the same.
  • The column used for ordering can be defined by the column number.
  • Duplicates are automatically eliminated in the final result.


The Minus Vs Except SQL Clause comparison can be confusing for many people. These two clauses are synonymous with each other and have similar syntax and results. Both Minus and Except help users skim through datasets to identify unique rows available only in the first SELECT query and not returned by the second SELECT query.

Technology – What Is GraphQL?


What is GraphQL? GraphQL is a short form for Graphical Processing Language, abbreviated as Graphical Language (GPL) which is a subset of the larger more comprehensive language Java. GraphQL is an easy to use, dynamic web application framework that allows developers to construct queries and return relevant information. GraphQL was designed internally at Facebook in 2012 and then publicly released in 2015.

GraphQL defines a set of generic functions that can be executed against any existing database. These generic functions allow developers to create dynamic web applications that respond to different user interactions with the web application. Some of these functions include the creation of views and data models. The use of these functions enables developers to define and reuse complex functionality, while separating business logic from user code. These advanced functions are very powerful for building fast, web application development.

There are some functions that are commonly available. Some of these functions are: insert, where, select, replace, update and remove. There are some generic functions that are not commonly available but are necessary for certain scenarios. These functions include: path, constant, URL path, URL query, root element and more.

GraphQL implementation is based on the use of the PHP language. There is no need to learn other programming languages as all the functionality is provided through the use of PHP. This makes it highly flexible and reusable. The use of plugins is also supported through the use of the MVC (model, view and controller) framework that allows developers to model the business logic behind the scenes. The use of plugins also ensures that there is a consistent code base and that functionality is consistently available.

GraphQLS is a server-side language and the development process is done entirely from the development server. The server side technology also provides support for the development of XHTML and XML documents. The use of a database is not necessary as there is no requirement to write any server side code. All the database access is done through a standard HTML form.

With a professional PHP developer, it becomes easy to build complex applications that are needed in today’s world. In addition to that, the developers ensure that the application is highly performant and that the performance level is satisfactory. The developers use functions such as: loops, recursion and grouping of statements. For the server side coding, the PHP programming language is combined with the MySQL database language and this enables easy creation of complex data structures.

In a nutshell, what is GraphQL? It is a simple yet powerful method that enables the developer to build extremely interactive web pages. The main aim of the web application development company is to provide high performance web application development services and this requires full knowledge of the source code as well as the server side codes. A developer who has completed his or her basic requirements can be short listed for the project. Once the web developer is chosen, he or she will be provided with a complete set of GraphQL scripts which will enable the development of the web application.

What is GraphQL and how does it help the company? Today every company needs to use the latest applications and solutions that are available in the market. A developer who has knowledge about the server side languages and GraphQL would be the best choice. In addition, the developer needs to be updated about the new technologies that are used by the company. A company can save a lot of money if the web developer uses the latest technologies and methods. This is where a company needs to give importance to the expertise of the experienced and trained web developer.
