  • Clang Profile Guided Optimizations Support Sent In For Linux 5.14 - Phoronix

    Compiling the Linux kernel with LLVM's Clang code compiler continues to be more featureful with plumbing now being added to handle profile-guided optimizations (PGO) to help in achieving greater performance for optimizing kernel builds for targeted workloads.

    Earlier this month I wrote about Clang PGO likely coming for Linux 5.14 and indeed the pull request was sent in on Monday. While GCC PGO for the Linux kernel was previously shot down, it looks like this new infrastructure will make it in for this new cycle.

  • Glibc 2.34 Adds "_Fork" Function Ahead Of Future POSIX Revision - Phoronix

    The GNU C Library (Glibc) has landed its _Fork function implementation as an async-signal-safe fork replacement that is also expected to be made part of the next POSIX standards revision.

    Going back to 2007 has been Glibc Bug 4737 of the fork function not being signal safe with glibc, unlike some BSDs and other platforms. Various developers have commented on it over the years due to deadlocks occurring in their programs such as if using fork() within a signal handler and other conditions met.

  • Sensible datetime scale for Gonum Plot

    Few months ago I posted a library for sensible int scale for Gonum Plot. There is a similar package I’ve developed to handle timescales.

    The integer one, being based on a recursive function, works with any number scale. Differently, this one will only work well with a timescale between 2 days and a couple of years. Extending it is not hard since it’s enough to add additional case statements in the switch, but I’ve not found use-cases for different timeframes so far. If you add additional options, please commit them back!

  • GStreamer Rust bindings 0.17.0 release

    A new version of the GStreamer Rust bindings, 0.17.0, was released.

    As usual this release follows the latest gtk-rs release.

    This is the first version that includes optional support for new GStreamer 1.20 APIs. As GStreamer 1.20 was not released yet, these new APIs might still change. The minimum supported version of the bindings is still GStreamer 1.8 and the targetted GStreamer API version can be selected by applications via feature flags.

    Apart from this, the new version features a lot of API cleanup, especially of the subclassing APIs, and the addition of a few missing bindings. As usual, the focus of this release was to make usage of GStreamer from Rust as convenient and complete as possible.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
