  Test-Driven Development? Give me a break...

Update: At the bottom of this post, I've linked to two large and quite different discussions of this post, both of which are worth reading... Update 2: If the contents of this post make you angry, okay. It was written somewhat brashly. But, if the title alone makes you angry, and you decide this is an article about "Why Testing Code Sucks" without having read it, you've missed the point. Or I explained it badly :-)Some things programmers say can be massive red flags. When I h...

  Learning Ruby and Ruby vs Lisp

The company I work for has a lot of legacy Ruby code, and as Ruby has become kind of a mainstream language, I decided to get a book about it and learn how it works. As my learning resource, I chose The Ruby Programming language by David Flanagan and Yukihiro Matsumoto as that receives great customer reviews, covers Ruby 1.8.7 and 1.9 and is authoritative because the language creator is one of the authors. The book makes a good read in general. There are plen...

  Basic Mistakes Developers Make When Creating APIs

Today, there are many tools that developers can use to create an API, meaning that some of them can come up with an API within a matter of minutes. However, there is a vast difference between just creating an API and building one that meets all your expectations, is reliable and secure. Some developers create APIs that work well but forget some basic things that, within no time, bring a lot of issues to the API users. In this article, we are going to talk about the basic mistakes that developers...

  "Programmer" is an Overgeneralization

"Beware of bugs in the above code; I have only proved it correct, not tried it." - Donald Knuth Earlier today, I came across a post during a google-fu session that claimed that no one should use the C++ standard library function make_heap, because almost nobody uses it correctly. I immediately started mentally ranting about how utterly ridiculous this claim is, because anyone whose gone to a basic algorithm class would know how to properly use make_heap. Then I started thinking about all the ...

  Programming Languages for Machine Learning Implementations

Machine learning algorithms have a much better chance of being widely adopted if they are implemented in some easy-to-use code. There are several important concerns associated with machine learning which stress programming languages on the ease-of-use vs. speed frontier.Speed The rate at which data sources are growing seems to be outstripping the rate at which computational power is growing, so it is important that we be able to eak out every bit of computational power. Garbage collected la...

  What to put on whiteboard during an interview

As a programmer, you may go through different kinds of programming tests while interviewing for jobs. The most famous and difficult one may be the whiteboard test for lots of people. Usually the interviewer will give the candidate an algorithm problem or case study and ask the candidate to implement the algorithm with his/her favorite programming language. The code to be written is not too much but it requires the candidate to thoroughly consider different edge cases. So wha...

  People working with computers seem to have a lot of spare time

People working with computers are a group of people who spend much time on communicating with PCs, Handsets and other programmed hardware devices. Usually, these people are thought as a group of busy people. When we see them, they are often sleepy and seem not caring about anything else. They often work day and night, spend many hours on finding and fixing an unknown bug or trying to meet the project deadline  Are they really so busy?  Lets see what some people think about them? Just f...

  Tips of Drafting an R Markdown Document

When presenting the data summary and exploratory analysis, we used to copy a lot of tables, charts from Rstudio to PowerPoint, which makes the presentation preparation painful. It becomes essential for data scientists to make use of better reporting tools, such as R markdown, Jupyter notebook to prepare the analysis presentation in a more efficient and organized way. Of course, we want this to be reproducible! In this post, I would like to share some tips of using the right tools to draw tables,...

  5 Lightweight PHP Frameworks For Creating An API

PHP is undoubtedly one of the most popular programming languages that offer a wide range of lightweight frameworks for building basic websites to REST APIs. These frameworks are powerful tools that have the potential to enhance productivity in order to deliver faster results without getting distracted from the best practices of development. Developing REST APIs with plain PHP is a tedious and time-consuming process. In order to sort this out, you only need to hire php developers who have a niche...
