      • DedoimedoThe Slimbook Titan is here

        So far, the Slimbook Titan is my most expensive laptop to date. It's also by far the most powerful one, with a spec that wouldn't shame many a desktop. Of course, the mobility comes at its price. And my deliberate choice to use Linux only also has implications. I will need to see whether I can truly step away from Windows once and for all. Or at least prove that this can be done painlessly by 2025, when Windows 10 goes EOL. Lots of pondering, lots of questions. We have a hypothesis, we need to test it.

        My Titan experiment should be a fun one. Well, I hope. So far, things had not gone that well, I must say. The delivery process was over-complicated and frustrating. The initial laptop setup wasn't as elegant as I expected. And on that cliffhanger, I must bid you farewell. In the next article, we will look at the installation, the system setup, hardware compatibility, and then some. It ought to be interesting. See ya.

      • It's FOSSEnd of the Road for GIF Recorder 'Peek' and Stock Tracker 'Markets' Linux Apps

        Peek was an open-source animated GIF recorder that came in quite handy for capturing the contents of a screen.

        Similarly, the 'Markets' app was an open-source app for Linux desktops and phones that allowed users to track stock market movements.

        Sadly, both of these apps have been discontinued for their respective reasons.

        Allow me to take you through more details.

      • The Register UKHow to get the latest Linux kernel on your Ubuntu box

        For significant subcomponents of Ubuntu – and its derivatives – you don't need to wait for the next release to appear. You can upgrade major parts on the fly.

        Here at Vulture Towers, we are working on a review of a machine with a 12th-generation Intel chip, and that's caused issues in some Linux distros. Back in 2021, we reported on work on kernel 5.16 to add Alder Lake support. Ubuntu 22.04 LTS shipped with kernel 5.15, though. The latest release, 22.10, includes the ageing kernel 5.19, which you also get in the latest update to "Jammy", 22.04.2.

        What's up, everyone?

        First of all, we wish every one of you a happy new year (yeah, we are kind of late to release this! ). We also hope 2023 will be a good one for you and your loved ones as well.

        During the last few months, we have been preparing a new release containing quite a few changes for you. This not only brings fundamental changes to one of our editions, but it also features a much improved garuda-update, Dracut as the initramfs tool of choice as well as a clean Qt interface for our setup assistant. Apart from that, we had some major changes to our infrastructure and a lot of little enhancements to all parts of the distro which we are going to take a closer look at now

      • HowTo GeekArch Linux vs. Ubuntu: Which Should You Use

        Ubuntu and Arch Linux have staunch and vocal supporters. If you’re considering using Linux or changing distribution, you’ll have people promoting both of these to you. But which is right for you?

        The notion to try out Linux can be spurred by many factors. Maybe you’ve heard of Linux and just want to find out more. Perhaps you’re dissatisfied with your current OS and you’re looking for an alternative. Maybe you find the idea of free and open source software intriguing, and worth investigating.

        The Raspberry Pi shortage has been a meme in hacker circles for what feels like an eternity now, and the Pi 4 seems to be most affected – though, maybe it’s just its popularity. Nevertheless, if you’re looking for a Pi 4, you would need to look far and wide – and things are way worse if you need the 8 GB version specifically. Or so we thought – [MadEDoctor] shows us that refreshing online store pages isn’t the only way, having successfully upgraded the RAM chip on the Pi 4 from 1 GB to 8 GB with help of a hot air gun.

      • HackadayThe Future of RISC-V and the VisionFive 2 Single Board Computer

        The hardware is reasonably impressive, but the utility hinges on the OS and software support. There’s a Debian image that’s seeing regular updates, with issues continually getting fixed. What we really care about is upstream status, and that process has started. There’s hope for a minimally booting system with kernel 6.3, though there are quite a few drivers to upstream before the system is fully usable with the vanilla kernel.

        And one of those drivers we have to mention is the GPU. The hardware is known as BXE-4-32 GPU, a GPU core from Imagination Technologies, and successor to the PowerVR architecture. Imagination is making a play for getting its designs built into RISC-V chips, and as part of that, has released open source drivers for its modern products. There’s an ongoing effort to upstream those drivers, and some enablement code has already landed in Mesa.

      If you're wary of committing your data to cloud services controlled by a corporation but you love the convenience of remote storage and easy web-based access, then you're not alone. The cloud is popular because of what it can do. But the cloud doesn't have to be closed. Luckily, the open source Nextcloud project provides a personal and private cloud application suite.

      It's easy to install and import data—including contacts, calendars, and photos. The real trick is getting your data from cloud providers like Google. In this article I demonstrate the steps you need to take to migrate your digital life from an Android device to Nextcloud.

        http://git.sv.gnu.org/gitweb/?p=grep.git;a=shortlog;h=v3.9
        or run this command from a git-cloned grep directory:
        git shortlog v3.8..v3.9

        q80RQJ7iPUyvNf60IuU7ushnAUz+7TE7tfSIrKFwtZk= grep-3.9.tar.xz

        Verify the base64 SHA256 checksum with cksum -a sha256 --check
        from coreutils-9.2 or OpenBSD's cksum since 2007.

        Use a .sig file to verify that the corresponding file (without the
        .sig suffix) is intact. First, be sure to download both the .sig file
        and the corresponding tarball. Then, run a command like this:

        gpg --verify grep-3.9.tar.gz.sig

        The signature should match the fingerprint of the following key:

        pub rsa4096/0x7FD9FCCB000BEEEE 2010-06-14 [SCEA]
        Key fingerprint = 155D 3FC5 00C8 3448 6D1E EA67 7FD9 FCCB 000B EEEE
        uid [ unknown] Jim Meyering <jim@meyering.net>
        uid [ unknown] Jim Meyering <meyering@fb.com>
        uid [ unknown] Jim Meyering <meyering@gnu.org>

        If that command fails because you don't have the required public key,
        or that public key has expired, try the following commands to retrieve
        or refresh it, and then rerun the 'gpg --verify' command.

        gpg --locate-external-key jim@meyering.net

        gpg --recv-keys 7FD9FCCB000BEEEE

        wget -q -O- 'https://savannah.gnu.org/project/release-gpgkeys.php?group=grep&download=1' | gpg --import -

        As a last resort to find the key, you can try the official GNU
        keyring:

        wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
        gpg --keyring gnu-keyring.gpg --verify grep-3.9.tar.gz.sig

        This release was bootstrapped with the following tools:
        Autoconf 2.72a.65-d081
        Automake 1.16i
        Gnulib v0.1-5861-g2ba7c75ed1

        NEWS

        * Noteworthy changes in release 3.9 (2023-03-05) [stable]

        ** Bug fixes

        With -P, some non-ASCII UTF8 characters were not recognized as
        word-constituent due to our omission of the PCRE2_UCP flag. E.g.,
        given f(){ echo Perú|LC_ALL=en_US.UTF-8 grep -Po "$1"; } and
        this command, echo $(f 'r\w'):$(f '.\b'), before it would print ":r".
        After the fix, it prints the correct results: "rú:ú".

        When given multiple patterns the last of which has a back-reference,
        grep no longer sometimes mistakenly matches lines in some cases.

      • In Any Other Context My Constant Stench of Garlic Is Repellent

        I've been awake for less than ten minutes and I can already feel the fatigue pulling my eyes inwards. Normally Herr Jet Lag doesn't last this long. Or does he? It's nearly five in the morning in Seminole. My time here so far has been wholly unproductive creativity-wise. Within me is a piercing guilt.

        Perhaps it is a gradually newfound perception of mortality that creates this guilt. It's not a guilt associated with any harm I've done or could do to others. It's as if I am cutting myself down with the blade of wasted time. True - I am out of sorts at the moment. Usually after the nastiness that accompanies travel, I am useless for days. I must conquer the uselessness - fight the lethargy. It's certainly not an easy task.

      • Announcement - New Chinukwawa Newsletter

        It’s a place for mine own projects. Currently only I have up the smolnet servers. And I just released the first edition of one of the projects, a Chinukwawa newsletter and resource site. Considering the amount of speakers is very low, I doubt this paper will win any Pulitzer. Regardless, the aim is language revitalization and indigenous language support in this UN Decade of Indigenous Languages. My hope is to stimulate interest in learning Chinukwawa amongst both indigenous and settler communities, and perhaps toward other indigenous languages. As such, the working language is Chinukwawa, but I expect if one or two people read it, I shall post a bit in what other languages for which I have barely passing marks, including English. The main course of the smorgasbord will naturally be interviews and blither. I aim to keep it â…” lighthearted, and â…“ grave. A change of pace for me, and one hopes somewhat salubrious.

        • Cross Compilers part 2

          In part one of this series, we built a cross toolchain capable of compiling C and C++ code on an x86_64 linux machine which will then run on a riscv64 linux machine using musl libc. As the final step, we compiled a simple `Hello world!` executable to test the toolchain. In part 2, we're going to go through using the cross compiler to build real world software, and explore some common pitfalls that are encountered due to build systems not being designed with cross compilation in mind.
