  • How to Encrypt and Decrypt a Partition in Linux

    When a Linux partition is encrypted, access to the partition’s stored data and storage space is inapplicable to users who do not have the right access/authorization. The same Linux partition can only be termed as decrypted if direct access to it is authorized.

    The authorization/decryption phase requires the user accessing the locked partition to provide a matching encryption key used to lock access to it.

  • How to Kill an Unresponsive SSH Connection in Linux - TREND OCEANS

    While working with a remote connection, it’s quite common to get into a situation where you are not able to interact with the remote system.

    And it is a frustrating moment when a remote SSH connection hangs after several minutes of unused connection, or perhaps even due to internet fluctuations.

    There might be many other reasons for the above cause, but it’s quite easy to kill an unresponsive SSH connection without killing the current shell.

  • Fix file permission errors on Linux | Opensource.com

    If you're sharing files between two users over the network or "sneaker net" (saving a file to a hard drive and copying it to a computer), you may encounter permission errors when you try to read or write the file. Even if you understand the concept of file permissions, you may not know exactly how to diagnose the problem or solve it. I used to perform data migration as a service, so I've run into my fair share of permission errors and ownership conflicts. Here's how I fix them fast.

  • 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.

  • Raspberry Pi Pico Used in Plug and Play System Monitor | Tom's Hardware

    Dmytro Panin is at it again, creating a teeny system monitor for his MacBook from scratch with help from our favorite microcontroller, the Raspberry Pi Pico. This plug-and-play system monitor (opens in new tab) lets him keep a close eye on resource usage without having to close any windows or launch any third-party programs. The device is Pico-powered and plugs right into the MacBook to function. It has a display screen that showcases a custom GUI featuring four bar graphs that update in real-time to show the performance of different components, including the CPU, GPU, memory, and SSD usage. It makes it possible to see how hard your PC is running at a glance.
