  • [RFC] Zstandard as a second compression method to LLVM

    The LLVM project currently has support for zlib as a compression algorithm. Usage of it varies from compression of ELF debug sections, to serialization of performance stats and AST data structures.

    We would like to add Zstandard (A.K.A. Zstd) as an alternative to zlib, which tends to achieve higher compression rates while being faster across the board. Using those for internal tooling could lead to speed improvements in places where we compress AST’s etc, without sacrificing the compressed size of them.

  • Takedown Notice Wipes Game Boy Advance Emulator From GitHub

    A popular browser-based Game Boy Advance emulator with nearly 100 working games was removed from GitHub this week. The takedown request was sent by the ESA, which acts on behalf of Nintendo and other game companies. The problem hasn't been sorted out completely, however, as nostalgic games can easily find alternatives, even on GitHub.

  • Russia’s Conti working on exploits for Intel ME BMC AMT IPMI – Intel ME the biggest security fuck up in computing history – sue Intel

    “The biggest network security threat today is a remote code execution exploit for Intel’s Management Engine.”

    “Every computer with an Intel chipset produced in the last decade would be vulnerable to this exploit, and RCE would give an attacker full control over every aspect of a system.

    If you want a metaphor, we are dinosaurs and an Intel ME exploit is an asteroid hurtling towards the Yucatán peninsula.” (https://hackaday.com/tag/intel-me/)

    Intel might have installed – over the course of at least a decade (to this day?) a closed source backdoor in your computer’s firmware, that might never receive updates and is hard to remove.
    Once this backdoor is fully cracked, everyone (Russia, China and North Korea) can use it.
    Having remote control over a server down to the BIOS is a neat feature.

    [...]

    another dramatic way to put it:

    “The biggest network security threat today is a remote code execution exploit for Intel’s Management Engine.”

    “Every computer with an Intel chipset produced in the last decade would be vulnerable to this exploit, and RCE would give an attacker full control over every aspect of a system.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. 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 MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
