  • Sizing Up Partitions » Linux Magazine

    Partitioning is a basic step in any Linux installation. Many users breeze past it, content to let the installer use a single partition, or else to accept its recommendations without much thought, sparing themselves the stress of learning yet another task. However, manually partitioning can help to isolate directories from each other, optimize performance, and aid in recovery when troubles arise. If manual partitioning takes some extra time, down the line, you might be glad you make the extra effort.

    As you probably know, Linux is organized into a series of directories, each with its own purpose. Directories can be on the same device, or else a mount point for a separate device. In either case, users are presented with a single directory tree. Usually, each device will be formatted with ext4, although recent Fedora releases default to Btrfs, or on servers, XFS. On systems that include a Windows installation, an ntfs or fat32 partition is included. Partitioning is done on a blank system, or from an external device so that no partition is mounted. Older tools such as fdisk are still around, but today's most common tools are parted (Figure 1) or gparted, its graphical equivalent.

  • How to Add Repository to Debian

    APT checks the health of all the packages, and dependencies of the package before installing it. APT fetches packages from one or more repositories. 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. The normal installation comes with default repositories configured, but these contain only a few packages out of an ocean of free software available. In this tutorial, we learn how to add the package repository to Debian.

  • 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: [...]

  • allow-new-zones in BIND 9.16 on CentOS 8 Stream under SELinux

    We run these training systems with SELinux enabled (I wouldn’t, but my colleague likes it :-), and that’s the reason I aborted the lab: I couldn’t tell students how to solve the cause other than by disabling SELinux entirely, but there wasn’t enough time for that.

  • Will the IndieWeb Ever Become Mainstream?

    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.

    The short answer to the question is a resounding no, and it all boils down to the fact that the IndieWeb is really complicated to implement, so it will only ever appeal to developers.

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.
