• Linux Bash Shell Special Characters

  There are a set of characters the Bash shell treats in two different ways. When you type them at the shell, they act as instructions or commands and tell the shell to perform a certain function. Think of them as single-character commands. If you want to master the Bash shell on Linux, macOS, or another UNIX-like system, special characters (like ~, *, |, and >) are critical. We’ll help you unravel these cryptic Linux command sequences and become a hero of hieroglyphics.

• Use Docker and Alpine Linux to build lightweight containers

  When it comes to Docker, sometimes less is more -- a maxim that applies especially to the base OS images installed in each Docker image. The use of a lightweight image -- one with less than 200 MB -- can result in significant resource and cost savings when used alongside optimized applications. A lightweight image also takes less time to deploy compared to a larger one, as it boots up faster. Most OS images are lightweight, with minimal compute resource requirements. But others, such as Windows containers, are huge. Alpine Linux is a super lightweight Linux distribution that's useful for Docker containers. In this Docker and Alpine Linux tutorial, we'll build an Nginx web server that demonstrates how small a Docker container image can be.

• Managing resources with cgroups in systemd | Opensource.com

  Cgroups manage resources per application rather than by the individual processes that make up an application.

• Improve your database knowledge with this MariaDB and MySQL cheat sheet | Opensource.com

  When you're writing an application or configuring one for a server, eventually, you will need to store persistent information. Sometimes, a configuration file, such as an INI or YAML file will do. Other times, a custom file format designed in XML or JSON or similar is better. But sometimes you need something that can validate input, search through information quickly, make connections between related data, and generally handle your users' work adeptly. That's what a database is designed to do, and MariaDB (a fork of MySQL by some of its original developers) is a great option. I use MariaDB in this article, but the information applies equally to MySQL.

10 Best Free and Open Source Linux Revision Control Tools

Version control systems play an essential role for developers. First up, they allow developers to safely store successive versions of source code. Besides providing a secure backup of the source code, this type of software lets developers revert back to a stable release if subsequent code changes have unforeseen consequences. Equally important, revision control tools enable team members to work simultaneously on a project’s code. If you have ever collaborated with other people on a project, you will appreciate the frustration caused by swapping files. Revision control is an excellent way to combat the problem of sharing files between developers without treading on each other’s toes. For open source projects having tens/hundreds of people working on the same code base, revision control software is essential.
