  • Kernel now 5.15.60 with RTLXXXU driver

    I have had email communications with Muthukrishnan, Realtek wifi not working, but it does work on a different Linux distribution. He has investigated firmware, but narrowed the problem down to a missing kernel driver. This is part of one of his emails:

    The issue appears to be that CONFIG_RTL8XXXU is not set in the kernel config setting. Since the firmware for my laptop is RTL8723BU, it appears to be not loading it at the time of booting.

  • 393 – Quantum of Solus – mintCast

    First up in the news: Vanessa is finally here, so is the Linux kernel version 5.19, which was published from an M1 Mac by Linus Torvalds

    In security and privacy, Sale of over a billion Chinese users’ data found, DuckDuckGo is (finally) blocking Microsoft trackers, and Linux 6.0 to have run-time verification for running on safety critical systems

    Then in our Wanderings, Bill is hearing things, Moss is losing power, Joe is soldering on, and Norbert is taming the fox

  • How SQLite Helps You Do ACID

    The rollback journal is a simple trick to simulate atomicity and isolation and to provide durability to a database. Simple tricks are the best kind of tricks when you write a database so it's a great place to start.

  • Level up your HTML document with CSS | Opensource.com

    When you write documentation, whether that's for an open source project or a technical writing project, you should have two goals: The document should be written well, and the document should be easy to read. The first is addressed by clear writing skills and technical editing. The second can be addressed with a few simple changes to an HTML document.

    HyperText Markup Language, or HTML, is the backbone of the internet. Since the dawn of the "World Wide Web" in 1994, every web browser uses HTML to display documents and websites. And for almost as long, HTML has supported the stylesheet, a special addition to an HTML document that defines how the text should appear on the screen.

    You can write project documentation in plain HTML, and that gets the job done. However, plain HTML styling may feel a little spartan. Instead, try adding a few simple styles to an HTML document to add a little pizzazz to documentation, and make your documents clearer and easier to read.

  • 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: [...]

  • Things You Can And Can’t Do

    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.

  • How to Install CUPS Print Server on Ubuntu 22.04

    If your business has multiple personal computers in the network which need to print, then we need a device called a print server. Print server act intermediate between PC and printers which accept print jobs from PC and send them to respective printers. CUPS is the primary mechanism in the Unix-like operating system for printing and print services. It can allow a computer to act as a Print server. In this tutorial, we learn how to set up CUPS print server on Ubuntu 22.04.

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.
