  • How to easily open files with sudo privileges in the GNOME File Manager | TechRepublic

    Not all Linux file managers are created equal. Some file managers have more bells and whistles than the average user will ever need, while other file managers are as inflexible as cold, hard steel. There are also those that ship with a bare minimum of features but allow users to extend the feature set with add-ons.

    Given how we so often take the file manager for granted, once you find a feature that could really make your daily life a bit more efficient, you realize just how important the tool is. Such is the case with the GNOME File Manager. Out of the box, it works great and includes enough features to get you by for a while. Eventually, however, you’ll find some features that could make things a bit easier.

A repository (package source) is basically a network server. The term "package" refers to an individual file with a .deb extension that contains either all or part of an application.

  • 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. Recording the whole desktop is easy (some readers may remember my post on Aeschylus which does just that) but it will include irrelevant (and possibly unwanted) parts of the screen, leading to unnecessarily large files. I couldn't immediately find a tool which did what I wanted on OpenBSD [1] but through a combination of xwininfo, FFmpeg, and hk I was able to put together exactly what I needed in short order. Even better, I was able to easily post-process the video to shrink its file size, speed it up, and contort it to the dimension requirements of various platforms. Here's a video straight out of the little script I put together: [...]

    This is an interesting question, thanks for asking it, Jeremy. I do have some history with the IndieWeb, and some opinions, so let’s dive in.

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. When a terminal received more data than it could display, there needed to be a way for the terminal to tell the remote host to pause sending more data. The control code 19 was chosen for this. The control code 17 was chosen to tell the remote host to resume transmission of data.
