  • Make Use Of ☛ How to Choose the Best Laptop to Install Linux

    It’s never been easier to find a laptop to install Linux. But given the choices available, it’s indeed overwhelming to choose the best of the lot.

    The choice of laptop operating systems can no longer be boiled down to Windows vs. macOS. Linux is growing into a major player in the laptop space and today, there are more laptops than ever that work with Linux. There are even companies that make laptops designed to be Linux exclusives.

    With this new wealth of options, how can you choose the best laptop to install Linux?

    Don’t ‘push’ files, commands and/or charts to Kubernetes using the CLI. Instead, automate your operations by having ArgoCD ‘pull’ your desired state, and keep your apps up to date and in sync. ArgoCD is a better way.

  • VESA Releases DisplayPort 2.1 Specification – VESA – Interface Standards for The Display Industry

    The Video Electronics Standards Association (VESA®) announced today that it has released DisplayPort 2.1, the latest version of the DisplayPort specification, which is backward compatible with and supersedes the previous version of DisplayPort (DisplayPort 2.0). VESA has been working closely with member companies to ensure that products supporting DisplayPort 2.0 would actually meet the newer, more demanding DisplayPort 2.1 spec. Due to this effort, all previously certified DisplayPort 2.0 products including UHBR (Ultra-high Bit Rate) capable products – whether GPUs, docking station chips, monitor scalar chips, PHY repeater chips such as re-timers, or DP40/DP80 cables (including both passive and active, and using full-size DisplayPort, Mini DisplayPort or USB Type-C connectors) – have already been certified to the stricter DisplayPort 2.1 spec.

  • ID Root ☛ How To Install Apache Guacamole on Ubuntu 22.04 LTS – idroot

    In this tutorial, we will show you how to install Apache Guacamole on Ubuntu 22.04 LTS. For those of you who didn’t know, Apache Guacamole is a clientless remote desktop gateway that supports standard protocols like VNC, RDP, and SSH and use HTML5 for remote connection. It allows a user to take control of a remote computer or virtual machine via a web browser. The server runs on most Linux distributions and the client runs on any modern web browser.

    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 Apache Guacamole remote desktop application 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.

  • Godot Engine ☛ Emulating Double Precision on the GPU to Render Large Worlds

    One of the problems with developing games with large game worlds is that objects start to jitter and teleport around as you move away from the world origin. This post is about how we overcame one challenge in particular and what we did.

    The Problem

    By default Godot uses single-precision floating point numbers to store things like object positions. While GDScript typically allows users to do user-space calculations with double precision, those calculations get truncated as soon as they are stored in Godot internal objects (like Vector3’s).

    This has been a problem for users who want to do things like make games that take place in a to-scale solar system. Users quickly hit floating point precision errors and noticed that movement becomes jittery and objects become scattered.

    As an example, take a look at this simple scene, we have a bunch of Godot’s scattered randomly and a person running back and forth across the screen.

The CPU runs at a not-too-rapid 1.1GHz, but can turbo-boost up to 2.8GHz. The basic tablet is all you get, the stylus is an optional extra.

  • Linux Magazine ☛ Juno Computers Announces New Tablet Available For Pre-Order – Linux Magazine

    Juno Computers brings to market one of the first commercial Linux tablets that could be consumer-friendly and a viable option for those wanting an open source mobile device.

    The promise of a Linux tablet has been one so many in the community have been holding their breath over. Every so often a company will make a promise, only to fail on the delivery. If Juno Computers has anything to say about it, that all changes with a Debian-based, Mobian Linux/KDE Plasma device.

    The new tablet has a 10.1″, full HD touchscreen that also has an optional stylus pen, which is an extra $22. The new tablet is powered by an Intel Celeron N5100 4 Core CPU that runs at 1.1 GHz and includes a 2.8GHz turbo and 8GB LPDDR4 RAM. Internal storage is 256 GB and is upgradeable to 1TB.

• The Register UK ☛ Google reveals another experimental operating system: KataOS • The Register

  Google, one of very few tech companies willing to experiment with new operating systems, has unveiled KataOS for embedded machine learning devices.

  KataOS was announced along with Sparrow on the Google Open Source blog. KataOS is the operating system design and Sparrow is the reference implementation, as the Weston display server is the reference implementation of Wayland.

  The plan is that KataOS will be “a provably secure platform that’s optimized for embedded devices that run ML applications.” Google is working with Antmicro, which created the seL4-sys crate. Currently the OS is being developed on the Arm64 instruction set, but the plan is to run it on openTitan, which uses RISC-V.

  • Dima Kogan: gnuplot output in an FLTK widget

    I make a lot of plots, and the fragmentation of tools in this space really bugs me. People writing Python code mostly use matplotlib, R people use ggplot2. MS people use the internal Excel thing. I’ve seen people use gtkdatabox for GTK widgets, rrdtool for logging, qcustomplot for qt. And so on. This is really unhelpful, and it would benefit everybody if there was a single solid plotting backend with lots of bindings to different languages and tools.

    This ‘QI’-style factum results from the notion that fish do not all belong to the same genus (or ‘family’, or ‘phylum’, or some other Biological category). If we take one genetic branch of fish as the real fish, then we miss out a lot of animals which everyone calls ‘fish’. But if we broaden our definition and include the other fish, we must include foxes in the same gene-line.

    Simply put, fish split early in the genetic line, and now we can’t name them according to their genetic classification.
