  • Delivering RPM packages securely and continuously with Jenkins and Hashicorp Vault: When you publicly deliver more than eight releases a day—like we do for Tuleap—making sure that users can verify the authenticity of the deliverables becomes a challenge. Over the past few weeks we have modified our Jenkins build pipelines to GPG sign every RPM package we deliver, thus enhancing the level of security we bring to every Tuleap user.
  • Learn regex the easy way: Regular expression is a group of characters or symbols which is used to find a specific pattern from a text.
  • Extremely Fast MySQL Backup and Restore Using Mydumper/Myloader: Mydumper and Myloader are utility software programs that allow you to perform extremely fast and reliable multi-threaded MySQL backup and restore which is written in the C programming language.

While a lot of people use shell scripts as an analog to a batch file in MSDOS, it can do so much more than that. Contrary to what you might think after a casual glance, it is entirely possible to write scripts that are reliable and robust enough to use in many embedded systems on a Raspberry Pi or similar computer.
