  • Bootlin toolchains integration in Buildroot

    Since 2017, Bootlin is freely providing ready-to-use pre-built cross-compilation toolchains at https://toolchains.bootlin.com/. We are now providing over 150 toolchains, for a wide range of CPU architectures, covering the glibc, uClibc-ng and musl C libraries, with up-to-date gcc, binutils, gdb and C library support.

    We recently contributed an improvement to Buildroot that allows those toolchains to very easily be used in Buildroot configurations: the Bootlin toolchains are now all known by Buildroot as existing external toolchains, next to toolchains from other vendors such as ARM, Synopsys and others.

    [...]

    Internally, this support for Bootlin toolchains in Buildroot is generated and updated using the support/scripts/gen-bootlin-toolchains script. In addition to making the toolchains available to the user, it allows generates some Buildroot test cases for each toolchain, so that each of those configuration is tested by Buildroot continuous integration, see support/testing/tests/toolchain/test_external_bootlin.py.

  • Intel Vision Processing Unit Patches Updated For The Linux Kernel

    As part of Intel's lengthy "Keem Bay" upstreaming for Linux as their latest-generation Movidius VPU offering, now that much of the core infrastructure bits are all mainlined, the latest focus has been on their Vision Processing Unit enablement. 

    The Intel Vision Processing Unit upstreaming is quite big and includes new xlink-pcie, xlink-ipc, and xlink-core drivers as part of the effort. This VPU was developed through Intel's acquisition of Movidius and can be used for computer vision processing on a locally attached camera or CV processing for a network or tethered camera setup. While most common will be the Keem Bay SoC on a PCI Express card, it can also be found in form factors as a USB dongle or M.2 card as a computer vision accelerator. 

  • Tomasz Torcz: KubeCon NA 2020 talks to watch, part 1 [Ed: Typical Linux Foundation. Slack and Zoom instead of Free software and all projects outsourced to Microsoft's proprietary GitHub]

    The main course of conference are talks. There were plenty. Sometimes there were a dozen or so parallel tracks, so I did not have a chance to watch everything. I'm slowly working through backlog of things I missed. The talks itself were pre-recorded, but after the talk there was a live Q&A session with the speaker. Sadly, the Q&A is not available in recordings below. I guess this was one of the exclusive perks for attendees.

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.
