Version 0.30 adds a new notification system. Similar to desktop notifications, it displays a small window with a title and message (called a toast) for a pre-defined number of seconds.

Hello. I wrote this blog post to serve as a reference for BRE/ERE regexp flavors. You'll also learn the differences between these tools — for example, awk doesn't support backreferences within regexp definition (i.e. the search portion).

Buffering and where it might cause issues

Syncthing is a continuous file synchronization program. It synchronizes files between two or more computers.

The playground allows you to learn about systemd interactively, right from your browser! Create examples without the danger of breaking your system, and without being distracted by hundreds of unrelated unit files.

Most people think assembly is only to be used to write toy programs for learning purposes, or to write a highly optimized version of a specific function inside a codebase written in a high-level language.

Well, what if we wrote a whole program in assembly that opens a GUI window? It will be the hello world of the GUI world, but that still counts.

As a programmer, you use hash functions every day. They're used in databases to optimise queries, they're used in data structures to make things faster, they're used in security to keep data safe. Almost every interaction you have with technology will involve hash functions in one way or another.

Hash functions are foundational, and they are everywhere.

But what is a hash function, and how do they work?

In this post, we're going to demystify hash functions. We're going to start by looking at a simple hash function, then we're going to learn how to test if a hash function is good or not, and then we're going to look at a real-world use of hash functions: the hash map.
