  • Book club: Our Software Dependency Problem

    A short while ago Daniel, Lars and I met to discuss Russ Cox’s excellent essay Our Software Dependency Problem. This essay looks at software reuse in general, especially in the context of modern distribution methods like PyPI and NPM which make the whole process much more frictionless than traditional distribution methods used with languages like C. Possibly our biggest conclusion was that the essay is so eminently sensible that we mostly just talked about how much we agreed with it and how comprehensive it was, we particularly admired the clarity with which it explores how to evaluate the quality of free software projects.

  • Building Packages with Buildah in Debian

    Building packages in Debian seems to be a solved problem. But is it? At the bottom, installing the dpkg-dev package provides all the basic tools needed. Assuming that you already succeeded with creating the necessary packaging metadata (i.e., debian/changelog, debian/control, debian/copyright, etc., and there are great helper tools for this such ash dh-make, dh-make-golang, etc.,) it should be as simple as invoking the dpkg-buildpackage tool. So what's the big deal here?

    The issue is that dpkg-buildpackage expects to be called with an appropriately setup build context, that is, it needs to be called in an environment that satisfies all build dependencies on the system. Let's say you are building a package for Debian unstable on your Debian stable system (this is the common scenario for the official Debian build machines), you would need your build to link against libraries in unstable, not stable. So how to tell the package build process where to find its dependencies?

    The answer (in Debian and many other Linux distributions) is you do not at all. This is actually a somewhat surprising answer for software developers without a Linux distribution development background1. Instead, chroots "simulate" an environment that has all dependencies that we want to build against at the system locations, that is. /usr/lib, etc.

  • jgmenu

    There is a new tool available for Sparkers: jgmenu.

    [...]

    Due to changes in the Debian testing repositories, the Obmenu and Obmenu-generator is not available and can not be installed on Debian/Sparky testing any more, so…
    The ‘jgmenu’ provides a pipemenu to the Sparky 6 Openbox edition instead of the two menu apps mentioned before.

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.
