Tighten up your code and identify errors before they occur with mypy. I've been using dynamic languages—Perl, Ruby and Python—for many years. I love the flexibility and expressiveness that such languages provide. For example, I can define a function that sums numbers:

Teaching kids about open source? Don't forget to teach them ethics as well. Back when I started college, in the fall of 1988, I was introduced to a text editor called Emacs. Actually, it wasn't just called Emacs; it was called "GNU Emacs". The "GNU" part, I soon learned, referred to something called "free software", which was about far more than the fact that it was free of charge. The GNU folks talked about software with extreme intensity, as if the fate of the entire world rested on the success of their software replacing its commercial competition.

Linux Journal's very first issue featured an interview between LJ's first Publisher, Robert Young (who went on to co-found Red Hat among other things), and Linus Torvalds (author of the Linux kernel). After 25 years, we thought it'd be interesting to get the two of them together again. You can read that first interview from 1994 here.

Create handy command-line utilities in Rust. This article is about text processing in Rust, but it also contains a quick introduction to pattern matching, which can be very handy when working with text. Strings are a huge subject in Rust, which can be easily realized by the fact that Rust has two data types for representing strings as well as support for macros for formatting strings. However, all of this also proves how powerful Rust is in string and text processing.

Free software will save psychology from the Replication Crisis. "Study reveals that a lot of psychology research really is just 'psycho-babble'".—The Independent.

Good question. That's what people say when they don't have an answer yet. And such is the case with the question in the headline. I started wondering about it following  a tweeted response by Raouf Eldeeb (@raouf777) to Privacy is Personal: It is also a fundamental right, not a privilege to be bestowed on anyone. The individual should have the right to determine the extent of his privacy.

A recent IDC InfoBrief identified Linux as the only endpoint operating system growing globally. While Windows market share remains flat, at 39% in 2015 and 2017, Linux has grown from 30% in 2015 to 35% in 2017, worldwide. And the trend is accelerating.

Ever wondered why programming in Bash is so difficult? Bash employs the same constructs as traditional programming languages; however, under the hood, the logic is rather different. The Bourne-Again SHell (Bash) was developed by the Free Software Foundation (FSF) under the GNU Project, which gives it a somewhat special reputation within the Open Source community. Today, Bash is the default user shell on most Linux installations. Although Bash is just one of several well known UNIX shells, its wide distribution with Linux makes it an important tool to know.

Grepping is awesome, as long as you don't glob it up! This article covers some grep and regex basics. There are generally two types of coffee drinkers. The first type buys a can of pre-ground beans and uses the included scoop to make their automatic drip coffee in the morning. The second type picks single-origin beans from various parts of the world, accepts only beans that have been roasted within the past week and grinds those beans with a conical burr grinder moments before brewing in any number of complicated methods. Text searching is a bit like that.
