Programming
Computer programming is designing and building executable computer programs to perform specific computations or accomplish specific computing results. It involves tasks such as analysis, generating algorithms, profiling algorithms’ accuracy, resource consumption, and implementing algorithms in a programming language called coding. The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task on a computer, often for solving a given problem1. Proficient programming, thus, usually requires expertise in several different subjects, including knowledge of the application domain, specialized algorithms, and formal logic.
Netezza / PureData – What is the maximum length of CHAR, VARCHAR, and NVARCHAR fields
During a recent project, I had reason to investigate what the maximum character field links for Netezza to be able to fit the data ETL ‘ed from the source. The constraints on Netezza character fields are not as long as some other databases, therefore, I thought I would document and a quick post for future reference. Knowing these limits will help with your ETL design and construction but you may know where to truncate your field input data. Data type Alias names InfoSphere DataStage data types (SQL type) Maximum Length Notes CHAR CHARACTER, CHAR(n), CHARACTER(n) Char 64,000 Fixed-length character string, blank …

DataStage – How to use single quoted parameter list in an Oracle Connector
While working with a client’s 9.1 DataStage version, I ran into a situation where they wanted to parameterize SQL where clause lists in an Oracle Connector stage, which honestly was not very straight forward to figure out. First, if the APT_OSL_PARAM_ESC_SQUOTE is not set and single quotes are used in the parameter, the job creates unquoted invalid SQL when the parameter is populated. Second, I found much of the information confusing and/or incomplete in its explanation. After some research and some trial and error, here is how I resolved the issue. I’ll endeavor to be concise, but holistic in my explanation. …
The Most Private and Secure Browser For PC 2022
While many leading web browsers are claiming to be the most secure and private browsers available, their policies are in direct contradiction. For example, popular browsers may store a great deal of personal information about you, and they may even reveal your location to third-party sites. To avoid falling victim to this deception, you should arm yourself with as much knowledge as possible. This article will outline the best and most secure browsers for 2022. Firefox and Chrome both claim to be the most secure and private browsers available today, but the two aren’t the same. Firefox and Chrome use …

What is Anki?
Anki is a good way to memorize and review information. Each day, you have a pile of flashcards to go through. Once you’ve finished all the cards, you’re done for the day. While you may worry that you’ll forget to review some of them, the algorithm is extremely effective and won’t let you down. Once you get used to the system, you’ll be able to work through your cards in quick bursts. Another great thing about Anki is that it’s very easy to customize and change. Users can add their own notes, images, videos, and more. Additionally, Anki is regularly …
Technology – A Brief Overview of A/B Testing
A/B Testing, also known as a Comparison/ Covariance analysis is a methodology used to compare the performance of various models under different sets of assumptions. A/B testing involves a comparison between two models and normally, there will be two types of models: A and B. A/B testing involve a randomized, controlled experiment using two versions, A and B, under specified assumptions. The results will be statistically significant when one of the models is significantly different from the other model. A test can be described as an estimate of the probability density function associated with a variable. The sample is the …
Technology – Python Vs. R for Data Analysis?
There are a lot of differences between R and Python, but both have their place in data science. If you’re new to data science, Python is the better choice for beginners. It has many great libraries and is free to download and use. The main differences between these two languages are the types of data you want to manipulate and the approach you want to take. In this article, we’ll explain the difference between R and its closest competitor, Python. Both Python and R can accomplish a wide range of tasks, so it’s hard to choose the right one for …
