In this article, I’ll show you how to write an extension module. Instead of plain C, I use C++ because most compilers usually understand both. I have to mention one major drawback in advance: Python modules built this way are not portable to other interpreters. They only work in conjunction with the CPython interpreter. So if you are looking for a more portable way of interacting with C libraries, consider using the ctypes module.

In the Java programming language, an array is an ordered collection of data. You can use an array to store information in a structured way. It's useful to know the various ways you can retrieve that data when you need it. It's worth noting that in Java, an associative array (also called a dictionary in some languages) is called a hashmap. This article doesn't cover hashmaps, but you can read all about them in my Using a hashmap in Java article.

For several years, I worked in the TV online and video-on-demand (VOD) industry. While working on a scheduler web application, I realized that there were no good solutions for electronic program guides (EPG) and scheduling. Admittedly, this is a niche feature for most web developers, but it's a common requirement for TV applications. I've seen and analyzed a number of websites that have implemented their own EPG or timeline, and I often wondered why everyone seemed to be inventing their own solutions instead of working on a shared solution everyone could use. And that's when I started developing Planby.

Why call C functions from Rust? The short answer is software libraries. A longer answer touches on where C stands among programming languages in general and towards Rust in particular...

Have you ever found a bug in code and needed to know when it was first introduced? Chances are, whoever committed the bug didn't declare it in their Git commit message. In some cases, it might have been present for weeks, months, or even years, meaning you would need to search through hundreds or thousands of commits to find when the problem was introduced. This is the problem that git bisect was built to solve!

We are doing this by redesigning the user experience on all fronts to make it more easy and […]

As a technical writer working for ATIX, my tasks include creating and maintaining documentation for Foreman at github.com/theforeman/foreman-documentation. Git helps me track versions of content, and to collaborate with the open source community. It's an integral part of storing the results of my work, sharing it, and discussing improvements. My main tools include my browser, OpenSSH to connect to Foreman instances, Vim to edit source files, and Git to version content.
