  • Path of Least Resistance

    In machine learning, optimizations algorithms often move towards a local minimum (or maximum) by a process called gradient descent that finds the path of steepest descent. In smaller dimensions, this looks a lot like the path of least resistance.

    Consumers often choose products that are on the path of least resistance.

  • Async Cancellation II: Time and Signals

    For the past few years I've been working on the async-std library, which provides an async implementation of the APIs exposed by std. However, we also added several new APIs related to things unique to async Rust: concurrency, control over execution, and the interaction between the two.

    These APIs were initially introduced in async-std as "unstable", and have been the main focus of my work to design since. On this blog there are numerous posts related to for example: concurrency, cancellation, and parallelism. Today I want to share a new experiment I've been working for time-based operations in async Rust. I've designed it as a stand-alone crate for now, but I intend to PR its addition to async-std in the near future.

  • We’ll see you at CSTA 2022 Annual Conference

    Connecting face to face with educators around the world is a key part of our mission at the Raspberry Pi Foundation, and it’s something that we’ve sorely missed doing over the last two years. We’re therefore thrilled to be joining over 1000 computing educators in the USA at the Computer Science Teachers Association (CSTA) Annual Conference in Chicago in July.

  • Upgrading Qubes 4.0.4 to 4.1.0

    For those running Qubes 4.0.4 looking to upgrade to 4.1.0, let’s review the upgrade process using a Librem 14. To get started, you’ll need a USB hard drive to store your backup and a USB flash drive to boot the upgrade ISO.

    Most file system formats will work as long as they support large files, but you’ll need something more than fat32. If your drive uses fat you’ll need to reformat with ext4, exFAT or NTFS. To reformat, install GParted.

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.
