  • How to Delay or Tell When to Update Snap Apps in Ubuntu | UbuntuHandbook

    Ubuntu automatically checks and updates all installed Snap packages 4 times every day. Here’s how you can delay or assign a certain time period for the automatic update.

  • Making a Video of a Single Window

    I recently wanted to send someone a video of a program doing some interesting things in a single X11 window.

Open Hardware: XON/XOFF and Raspberry Pi Pico

  • From XON/XOFF to Forward Incremental Search

    In the olden days of computing, software flow control with control codes XON and XOFF was a necessary feature that dumb terminals needed to support.
