    • Make Use OfThe 4 Main Types of User Accounts on Linux

      User accounts are a key concept on Linux. Primarily, they help you manage access control on your system. In addition, they allow multiple users to log in at any given time, and they are critical for the security of a system.

      Without user accounts, it would be hard to control who has access to what part of a Linux system. Linux has four main types of user accounts. Here's everything you need to know about them.

      The last week of March was full of great news, especially for Ubuntu users who got the beta version of the upcoming Ubuntu 23.04 release, a major Ubuntu Touch update for their Linux phones and tablets, and a new official flavor, namely Ubuntu Cinnamon.

      But this week brought a lot of other goodies like a new major Blender update, a new Linux laptop for gamers from System76, and much more. Check out the hottest news of this week and access all the distro and package downloads in 9to5Linux’s Linux weekly roundup for April 2nd, 2023, below.

        This release continues to appear very normal and boring, which is just
        how I like it. The commit count says that we've started calming down
        right on schedule, and the diffstat looks normal too.

        Of course, there may be something nasty still hiding, so you never know, but at least for now we seem to be all set for a normal release in three weeks. Knock wood.

        If the diffstat for rc4 week was a bit unusual in how drivers didn't completely dominate, then rc5 makes up for it, with pretty much 75% of the diff being drivers. And it's all the usual ones that dominate: networking and gpu drivers make up for over half of it, and the rest is a random mix of other stragglers (x86 platform drivers, input, pinctrl, sound..).

        Outside of drivers, it's various random stuff. Architecture fixes (arm64 kvm, riscv, powerpc), filesystems (btrfs, cifs), core networking, documentation and tooling.

    • Distro WatchReview: Alpine Linux 3.17.2

      Something which regularly floated through my mind while using Alpine Linux was this experience reminded me of why I started using Linux regularly in the first place, back in the 1990s. Back then, when Windows 98 was king of the desktop market, I was running a minimal Linux distribution at home. The Linux experience was unusually light, clean, flexible, and transparent. It was something I could examine, tweak, and it just did what I told it to do, nothing more or less. There was a pleasant simplicity to the experience.

      Alpine Linux is like that. It's small, light, and super fast. There are utilities which make the system easier to use (such as the APK package manager and OpenRC), but these tools just perform one task - well and quickly. They don't try to add a lot of features or guess what I want them to do. Alpine has an unusually clean design while also supplying tools to make our lives easier.

      • HaikuOSHaiku Depot Server Technology Modernisation

        This article is cross-posted from Andrew Lindesay’s blog here.

        Java technology has been moving forward much faster in recent years with more frequent updates. Java 17 Long Term Support (LTS) was introduced in September 2021 and will be followed by Java 21 LTS in September 2023.

        With HaikuDepotServer (HDS) still on Java 11 introduced in September 2018, it was time to upgrade to 17 and then also make the transition from Spring 5 to SpringBoot 3 which was released in November 2022. Spring is a base technology for SpringBoot with SpringBoot providing more configuration and functionality by convention.

        These upgrades will bring HDS up to date with the current state of the art in backend Java and allow HDS to be maintained more easily going forward.


        The following are the main blocks of work undertaken to complete this modernisation.

        Fedora 38 Breaks Accelerated Video Playback in Firefox. breaks logins in SeaMonkey.

        It’s a double feature today.

        Apparently, in Fedora 38, they’ve made it so if you’ve already performed surgery on the rest of Fedora to re-enable accelerated video decode on your computer, with the new mesa-drivers-freeworld package on RPM Fusion (if you have non-Intel hardware) or the pile of Intel-media-driver packages, as well as the gstreamer1-vaapi packages, Firefox as an RPM or Fedora Flatpak won’t play video using hardware acceleration, so things become a slideshow.

        My learning project was a Wordle Guess Generator. I will show you how I used this project to create a self-guided learning plan. Motivated partly by my desire to have good guesses for Septle (a seven-letter guessing game), this project has been a crucial part of my journey to learn R. Practicing and learning coding skills were more important to me than devising the optimal strategy; if you are interested in “the best” Wordle strategy, then you will probably find much better answers by Googling.

        I learned how to put functions in a separate file and call them from my many script. This can make long code much easier to read. Here, I’ve included the helper functions in-line and commented out the source("code/helper-functions.R") in the main code. I’ve also set up switchable troubleshooting help with verbose and debug_detail parameters in my functions. Setting them to TRUE provide more info as the functions are executed.

        Barcodes were initially patented by Norman Joseph Woodland and Bernard Silver in the United States in 1952.

        But it wasn't until nearly two decades later, in 1971, that US engineer George Laurer perfected the technology and moves towards its commercialisation began.

        On April 3, 1973 the standard to identify products was agreed by a number of large retailers and food companies. It later became known as EAN-13, which stands for European Article Number and the number of digits in the barcode.

      • How to Stop a Cold Before it Takes Hold

        I am currently reaping the benefits of a tried and true technique of preventing an imminent cold and I wanted to share it with y'all.

        For some background, two days ago I felt a little tickle in the back of my throat. I didn't have a fever, chills, or any other symptoms that would suggest I would be sick. However, I knew that I couldn't be too careful when it came to stopping a cold.

      • How To Buy Shoes

        Those who've lived with me know that I've always worn the same type of shoes each day. During the years that I needed that style for use with my uniform I developed a preference for that particular style that stuck with me ever since. It took me a few years in the beginning to find which manufacturer's black oxfords worked best for me, but I soon settled on the Red Wing Shoes Style 101. That's what I've worn ever since, buying two pair at time so I can alternate between them -- shoes last much longer if they dry thoroughly between wearings.

    • Technical

      • Voice notes and Keyboards

        I've recently found myself becoming a big fan of voice notes. I'll usually send rambling voice notes to my friends on signal when I want to convey a lot of random information and I'm too lazy to type.

        Voice notes are great in a lot of circumstances, but not always. For instance, when I'm with other people, it can be weird or even rude if I'm blabbering into my phone for a minute and a half instead of silently typing. There is also the issue of coherence. I prefer writing communication over verbal because I can better organize my thoughts, edit, and clarify as I type. When I send a voice note there could be six different tangents that lead to nowhere by the time I send it.

      • Programming

        • Source controlled dotfiles

          It's not too uncommon to come across tech folk managing their dotfiles in source control. Conceptually, this makes a lot of sense - you tailor your configurations for certain programs, you want to be able to bring those around with you and also make sure if you break something, you can revert it. Plus, they're just text, so it makes sense, right?

          Sort of.

        • High-level languages in production

          I'm interested in a migration path from prototypes written in, e.g. Scheme or Prolog. So even though I really like ISLisp, it probably doesn't satisfy the requirements for commercial, production-quality. Notably, I've ignored my own advice and two of these platforms are non-standardised languages. I justify this because this is deciding for a commercial product, whereas deciding for learning is better limited. Also, although it may have only been half-hearted, I never was quite satisfied with SML for a real project. For example, if I use compiler extensions (as is very likely), libraries I try to integrate may not know about these extensions to interwork with them.
