  • The State Of OpenCL To Vulkan Compute Layers On Linux In April 2021

    It is, in theory, possible to run OpenCL applications on Linux using any graphics driver capable of doing Vulkan Compute. We have examined the alternatives for doing so and found them to be technically interesting and practically useless. It may become possible to run Blender with OpenCL compute using Vulkan at some point in the far distant future. Don't expect to be able to do that today or next month.

  • Mike Blumenkrantz: Between Loads

    I’m typing this up between loads and runs of various games I’m testing, since bug reports for games are somehow already a thing, and there’s a lot of them.

    The worst part about testing games is the unbelievably long load times (and startup videos) most of them have, not to mention those long, panning camera shots at the start of the game before gameplay begins and I can start crashing.

    But this isn’t a post about games.

    No, no, there’s plenty of time for such things.

    This is a combo post: part roundup because blogging has been sporadic the past couple weeks, and part feature.

  • Sid Meier: More than Just Civilization

    Let’s face it. The video games world is not getting any younger, and the most famous creators of yesterday are now well past 60. Sid Meier is no exception. I picked up his memoir and it was a good read. I am now pretty confident that we will see more publications in the same vein, as the age of pioneers reaches an end.

    For Linux gamers, Sid Meier’s current company, Firaxis, is a well known benefactor – one of the few friendly to our cause: Civilization 5, 6, and Beyond Earth have all been ported to Linux by Aspyr with the blessing of Firaxis. Even back in the Loki days, Civilization: Call To Power was one of the first games ported to Linux… while this was not a game by Sid Meier – just one from Activision who had secured the rights to the franchise. This is one of the things you will learn as you go through this memoir.

  • My Dog's Garage Runs OpenBSD

    I was inspired by the April 2017 article in undeadly.org about getting OpenBSD running on a Raspberry Pi 3B+. My goal was to use a Raspberry Pi running OpenBSD to monitor the temperature in my garage from my home. My dog has his own little "apartment" inside the garage, so I want to keep an eye on the temperature. (I don't rely on this device. He sleeps inside the house whenever he wants.)

    If anything seems wrongheaded, please chalk it up to a frothy mixture of enthusiasm, ignorance, stubbornness, and "just-because-I-wanted-to-do-it-this-way-ness."

  • News: Finland implements API framework proposed by the European Commission

                         

                           

    The Ministry of Finance set up the project on opening up and using public data in Finland on 30 April 2020. It will put into effect the aims given in the Government Programme by promoting wider and more effective public data use through society. The project will last until the end of 2022 and aims to promote the coherent use of data and functions, primarily through APIs. At the moment, there are no common principles for API development in the public sector in Finland.

  • 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.
