  • Supply Chain Attacks & Package Managers

    I think I agree with this, essentially. We do need to change the way we do dependencies when developing - and having someone else review packages would help reduce supply chain attacks.

    I wanted to try and figure out if this solution - use official Linux distribution packages instead of language ones - would work in practice, what that might look like, and how that might scale.

  • Open source R&D programme contributes 9.6 million € to "digital commons"

    Today a coalition of 12 not-for-profit organisations from across Europe launches the first open call for a large new research programme, NGI Zero Entrust. The ambitious programme is part of the Next Generation Internet initiative which was initiated by the European Commission in 2016. The programme is the next iteration of NGI Zero, which is one of the most ambitious funding programme designs of its kind — providing bottom-up funding to create digital commons such as free and open source software, libre hardware and open standards with a pipeline of tailored support to help mature the technologies in question.

  • The curse of strong typing

    So whereas Python has an "integer" and "float" type, Rust has different widths of integer types, like C and other system languages.

  • Hot Pi projects for hot weather.

    It’s hard to believe that summer is already here but it’s not hard to believe that makers have been super busy churning out some super cool Raspberry Pi projects. As the weather warms up for those in the northern hemisphere, so do the soldering irons of makers around the world.

    The makers featured in our list this month pulled out all the stops, using the best of the best Raspberry Pi accessories, HATs and more with some of the most creative concepts we’ve seen yet. Even if you don’t have cool accessories, these will show you how a little bit of ingenuity and programming can take your project to the next level.

  • How fast are Linux pipes anyway?

    Section 4 is the heaviest on Linux kernel internals, so it might be interesting even if you’re familiar with the other topics treated in the post. For readers not familiar with the topics treated, only basic knowledge of C is assumed.

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.
