  • QuatBot released – Matrix Meeting Manager

    QuatBot is a Bot for use in text-chat. So there are no pretty screenshots of it in action, or what the UI looks like: pick your favorite Matrix client (I switch between nheko and neochat depending on which has a more recent release fixing bugs that annoy me).

  • AIfES releases exciting new version of TinyML library for Arduino

    Last July AIfES (Artificial Intelligence for Embedded Systems) from the Fraunhofer Institute for Microelectronic Circuits and Systems (IMS) was launched. This open source solution makes it possible to run, and even train, artificial neural networks (ANN) on almost any hardware, including the Arduino UNO.

    The team hasn’t stopped work on this exciting machine learning platform, and an update just landed that you’ll definitely want to check out.

  • Drew DeVault's blog: Status update, January 2022

    I also implemented an efficient path manipulation module for the standard library (something I would really have liked to have in C!), and progress continues on date/time support. We also have a new MIME module (just for Media Types, not all of MIME) and I expect a patch implementing net::uri to arrive in my inbox soon. I also finished up cmsg support (for sendmsg and recvmsg), which is necessary for the Wayland implementation I’m working on (and was a major pain in the ass). I spent some time working with another collaborator, who is developing a RISC-V kernel in our language, implementing a serial driver for the SiFive UART, plus improving the device tree loader and UEFI support.

  • Project audit experiences | Will's Blog

    Back in January 2020, I wrote How to pick up a project with an audit. I received some comments about it over the last couple of years, but I don't think I really did anything with them. Then Sumana sent an email asking whether I'd blogged about my experiences auditing projects and estimating how long it takes and things like that.

  • Hack The Web Without A Browser | Hackaday

    It is a classic problem. You want data for use in your program but it is on a webpage. Some websites have an API, of course, but usually, you are on your own. You can load the whole page via HTTP and parse it. Or you can use some tools to “scrape” the site. One interesting way to do this is woob — web outside of browsers.

  • The new Qt Quick Compiler technology

    It's been a while since we've heard about what goes on inside and around Qt QML, our engine to interpret the QML language (not counting the recent announcement, that is). The last post strictly about this topic was what Lars wrote in 2018.

    We've been so silent because we've been prototyping new ways to make your QML run faster, and some of them turned out to be dead ends. There is no tracing JIT after all. This isn't cool, so we were somewhat silent. But now there is something to say. And, mind you, it's not cool either. It's hot. But let me take a step back first.

  • Bash scripting(III)

    This is the third article of a series focused in Gnu Bash scripting. On the first article we’ve just created a simple script with commands, one after another. We also saw some variables use.
    The second article covered some bash control structures. This one will cover redirections, pipes, and command substitution.

  • 2022.03 RakuCon How? – Rakudo Weekly News

    Andrew Shitov is asking for the community’s opinion on whether or not to have an in-person Raku Conference in Riga in 2022 in The Raku Conference Update. Cancelling an in-person event now, means no financial risk, which seems safest.

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.
