  • OSD32MP1-RED full-featured STM32MP1 development board launched for $265

    The board ships with a USB cable and a camera gender converter. Since the goal is to promote the company’s SiP, they’ve made available the PDF and EAGLE hardware design files for the board. “Trusted Debian” and “Trusted OpenSTLinux” MicroSD card images are also been made available and can be found together with the device tree files for Linux 4.19 and U-boot 2018.11, and a getting started guide on the product page.

  • The Old Desktop Switcheroo

    In August 2019, I tweeted about how I’d been running KDE Neon for eighteen months, since February 2018, and how I was switching back to GNOME Shell on my primary laptop. In that thread I also suggested I might switch back!

    [...]

    A quick reboot and I’m back on KDE Plasma - A.K.A. “Kubuntu”, from the Ubuntu Hirsute (to be 21.04, soon) archives.
    One thing I really love about Ubuntu, is the diversity of packages in the archive. I didn’t need to wipe and re-install, just tell apt to install one package (or task in this case), go and grab a coffee and it’s mostly done. I think I had one question to answer during the install about whether I wanted to keep gdm3 or switch to sddm, I chose the latter.

    Once rebooted I was able to fiddle around a bit with defaults like the theme - Breeze Dark - default terminal font in Konsole - IBM Plex Mono, and move the launcher to the correct location on the left. I also fiddled around with some of the default keyboard shortcuts, as that muscle memory is well ingrained. That’s mostly it!

  • Ubuntu Blog: All About That Base

    Snapcraft is our delightful tool for building snaps. It’s not the only way to build them, but it’s certainly a popular one.

    A benefit of Snapcraft is that typically a developer can configure the packaging definition once, and not have to update it for a long time. Snapcraft will keep cranking out releases, via CI or another build system.

    Software moves on though. It pays to re-visit snaps which were developed and published a while back, to see what improvements can be incorporated. Let’s take a look at one update which can reap benefits.

    In the beginning

    Snapcraft was originally conceived and built around Ubuntu 15.04 and stablised during the time of Ubuntu 16.04 LTS (Long Term Support). Some assumptions are made at build-time that software would compile on an Ubuntu 16.04 LTS system. At runtime, the core snap would be leveraged as a lean base on which to execute.

    When Ubuntu 18.04 LTS was released, a newer core18 base was published, and the base keyword introduced into the snapcraft.yaml syntax. Snap publishers could now specify the following in their yaml:

    base: core18

  • 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.
