  • An Opinionated Guide to xargs

    Apologies to the author for the criticism, but it generated a great discussion! Here is what lies ahead:

    An introduction to xargs, and a discussion of alternatives.

    Tips on using it, accompanied by #sample-code in the blog-code/xargs directory.

    High-level thoughts on shell and the Oil language.

  • 3D Printing Liquid Crystal | Hackaday

    If you think at all about liquid crystals, you probably think of display technology. However, researchers have worked out a way to use an ink-jet-like process to 3D print iridescent colors using a liquid crystal elastomer. The process can mimic iridescent coloring found in nature and may have applications in things as diverse as antitheft tags, art objects, or materials with very special optical properties.

    For example, one item created by the team is an arrow that only appears totally green when viewed from a certain angle. The optical properties depend on the thickness of the material which, being crystalline, self-organizes. Controlling the speed of deposition changes the thickness of the material which allows the printer to tune its optical properties.

  • Stephen Michael Kellat: Late August Update

    I learned about edbrowse from the latest episode of the Ubuntu Podcast. If I ever wind up using an actual teletype for a terminal that might be quite handy.

    [...]

    The testing manifest for Impish Indri shows only vanilla Ubuntu desktop shipping an image for Raspberry Pi. Considering my working “desktop” at the moment is a Raspberry Pi 4, any testing efforts on my part may wind up limited as I do not normally test vanilla Ubuntu desktop.

  • Recent and not so recent changes in OpenBSD that make life better (and may turn up elsewhere too)

    Known to be "functional, free and secure by default", the OpenBSD operating system has played an important role in open source for more than a quarter century. It has also been fairly central to what I have done for the last two decades and some. What follows is my personal view of what life with OpenBSD has been like, with an emphasis on moments and developments that I feel made life, or at least my life, better.

  • Quake Remaster's New MachineGames Episodes, Explained

    Amidst 2021's QuakeCon festivities, Bethesda and id Software released a remaster of the original Quake seemingly out of nowhere, featuring not only the game's original campaign and a number of technical updates, but its original two expansion episodes and two more created by MachineGames. The remastered version of Quake runs effortlessly on console and PC, supports resolutions up to 4K, and even lets everything jump into the same deathmatch lobbies thanks to quick play. It also canonizes two brand new episodes of the game developed by MachineGames. Best known for their updated take on Wolfenstein, both Dimension of the Past and Dimension of the Machine show up on the main menu alongside the original campaigns, expanding the breadth of this classic FPS and providing brand new content to a hungry retro FPS audience.

  • 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.
