  • How to update Linux Mint to Mint 21 | ZDNet

    It's not too hard to move from Linux Mint 20.3 to the long-term support of Linux Mint 21. But it's not a walk in the park, either.

  • How to Make Your Apps Start in Specified Workspace in Ubuntu 22.04 | UbuntuHandbook

    When you try to open an application in Ubuntu, Fedora or other Linux with GNOME, it’s possible to specify in which desktop workspace the app window should start!

    Most operating systems today have multiple desktops to organize unrelated ongoing projects. In Ubuntu Linux, we usually called them “workspaces”. For most common used applications, user may even let them start automatically in specified workspace to improve workflow efficiency.

  • Plan to sync PKGget and apt-dpkg

    I know this will interest a few people. I have been asked whether the 'apt' Debian package manager can be installed in EasyOS. Yes, it can, but the native package manager, 'PKGget', originally called the 'PPM' (Puppy Package Manager), does not "talk" with apt, so they won't have any idea what the other is up to.

    There have been some pups with both the apt and ppm, and I think that VanillaDpup does have some basic syncronization. Just from memory, last time that I played with it, I think that apt recognized the existing packages in the build, at first bootup, listed in file 'woof-installed-packages'. But there was no cooperation beyond that.

  • How to Install Tor Browser in Ubuntu 22.04 or 20.04 - ByteXD

    Tor browser is a secure browser that routes web traffic through the Tor network. Volunteers run Tor servers. It ensures users’ privacy and anonymity. You are free of network surveillance when you use Tor browser to browse the Internet. The onion icon in Tor symbolizes that, like an onion, Tor has layers to encrypt your internet connection.

    However, there are some disadvantages to using Tor. You might feel browsing to be a bit or considerably slower than your normal experience. Also, Tor users are blocked by some major websites. Even some governments try to block Tor and outlaw it.

  • How To Install Dropbox on Ubuntu 22.04 LTS - idroot

    In this tutorial, we will show you how to install Dropbox on Ubuntu 22.04 LTS. For those of you who didn’t know, Dropbox is application software that is operated by Dropbox inc. It provides cloud storage to store and access the data online by syncing the user device. It provides a free account with 2 GB storage and paid plans for more. A big advantage of using Dropbox is that you can share large files/folders by sharing the dropbox links rather than sending those large files.

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Dropbox file hosting service on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

  • 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: [...]

    And it got me thinking about what you can and can’t do — what you do and don’t have control over.

  • 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.
