Looking at ProtonDB, people are complaining about stutters. Some are reporting that the 64-bit version stutters, whereas the 32-bit version works. Unlucky for me, GOG only has a download for 64-bit on Linux. One comment says there is “a half a second freeze every few seconds”, which seems similar to my experience.

There has to be an answer why the client stutters, the developers must have tested this configuration! As a side note, I am wondering if the 64-bit version worked at some point, but without a good starting point it is hard to test. So let’s investigate where the pauses are coming from. Linux features a whole suite of tools to debug many different aspects from performance to correctness. And here I am assuming that the stutters are not inherent in the game logic, because the 32-bit version works correctly.

So you want to be a VTuber, but you already have a custom avatar that you really like in VRChat. Surely there's a way to make it work, right? This tutorial is going to cover the problem, how I do it and everything I learned along the way.

To say that VR is in its infancy is an understatement. This early on in the game, there are many different ecosystems and each of them really came up with their own avatar format out of necessity. As such, there's a lot of vastly different and incompatible ecosystems for this kind of avatar data. However, a common avatar data interchange format is starting to crop up organically: VRM. This format mostly came from the efforts of Japanese VTubers, and as such most 3d VTubing software supports it.

However, you still have your avatar stuck in VRChat format, thus this article exists.

Redis is an open-source in-memory datastore used as a database, cache, and even a message broker. Redis can be used easily with docker and docker-compose for local development as a cache to a web application. In this post, we will set up Redis with docker and docker-compose, where Redis will be used as a cache for a Node.js/Express.js REST API with PostgreSQL as the main database, let’s get started!

It's the first of the new year, which means we ought to do something momentous to mark the occasion, like a short piece about telephones. Why so much on telephones lately? I think I'm just a little burned out on software at the moment and I need a vacation before I'm excited to write about failed Microsoft ventures again, but the time will surely come. Actually I just thought of a good one I haven't mentioned before, so maybe that'll be next time.

Anyway, let's talk a little bit about phones, but not quite about long distance carriers this time. Something you may or may not have noticed about the carriers we've discussed, perhaps depending on how interesting you find data communications, is that we have covered only the physical layer. So far, there has been no consideration of how switches communicated in order to set up and tear down connections across multiple switches (i.e. long distance calls). Don't worry, we will definitely get to this topic eventually and there's plenty to be said about it. For the moment, though, I want to take a look at just one little corner of the topic, and that's multifrequency tone systems.

In this guide, we will learn how to install and configure Elasticsearch on Ubuntu 20.04

Elasticsearch is a distributed search and analytics engine built on Apache Lucene. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Elasticsearch has quickly become the most popular search engine and is commonly used for log analytics, full-text search, security intelligence, business analytics, and operational intelligence use cases.

We already talked about using flatpak packages in a previous tutorial: with this technology we universally distribute applications, which are packaged together with their dependencies and run inside a sandbox, isolated from the rest of the system. In this tutorial we see how to build and distribute an application inside a flatpak.

The objective is to install the NVIDIA drivers on Ubuntu 22.04 (Jammy Jellyfish) Linux and switch from a default opensource Nouveau driver to the proprietary Nvidia driver.

To install Nvidia driver on other Linux distributions, follow our Nvidia Linux Driver guide.

The name KDE comes from “K Desktop Environment.” For those not familiar with KDE Desktop, it is a free, open-source desktop environment. It provides Linux users with an alternative graphical interface to customize their desktop environment and applications for everyday use enhancement.

In Debian’s case, this is GNOME. Besides the graphical enhancements and changes, it is also a lightweight, fast, smooth environment with superior performance compared to native shipped desktops with some Linux Distributions.

In the following tutorial, you will have learned how to install KDE Desktop Environment on your Debian 11 Bullseye Desktop.

Rust has been adopted by hundreds of big companies in production environments. From applications like Dropbox, Firefox, and Cloudflare, to embedded devices and scalable web services, Rust can be used on all those types of applications and deployments.

rustup is a tool part of the Rust project that allows you to install Rust programming language to your system. Using rustup allows developers easily to manage and maintain Rust. Also, it enables you to switch between stable, beta, and nightly compilers and makes the cross-compiling process easier.

In this guide, you will learn how to install Rust programming language on the Debian 11 Bullseye. We will be using the rustup toolchain for installing and managing Rust on the Debian system.

Gitea is a free, open-source, and self-hosted solution for Git servers. Gitea has written in the Go programming language, a lightweight application, available as the binary package that can be installed on most of the platforms including Windows, Linux, and macOS. It is one of the robust, scalable, fast, easy to use and alternatives to GitLab.

Gitea offers many features including a repository file editor, bug and time tracking, repository branching, file locking, built-in wiki, merging, Multiple database support, Easy upgrade process, Built-in Container Registry, and much more.

In this tutorial, I will show you how to install Gitea from binary with PostgreSQL on Debian 11.

Ruby on Rails or RoR or Rails is a free and open-source web application framework written in Ruby with the MIT License. It is a full-stack web framework that uses the model-view-controller (MVC) pattern.
The Rails web framework provides structures for a database, web service, and web pages. Also, Rails includes some important tools such as scaffolding, Puma, Gems, etc.

One uniqueness or key identifier of different Linux distributions is in the package manager they use to update, install, configure, and uninstall various targeted software packages. In Arch Linux, the package manager is called Pacman.

This tutorial seeks to walk you through some commonly used and unique Pacman commands that will make your Arch Linux interaction and experience easier and much more memorable.

It is highly advisable to be a root user or have Sudoer user privileges on your Arch Linux system to fully benefit from what the Pacman command has to offer.

Git is an indispensable part of the code-sharing development workflow. Be you a beginner or an expert, this powerful version control system is the first thing you are expected to learn when working with open source code. You don't need to know everything under the sun when it comes to Git, but knowing specific hacks makes sharing your code a lot easier on platforms like GitLab, so you can collaborate with developers far and near. If there's something you're not sure about, git --help can come to your rescue.

I'm amazed every day by the amount of control that knowing Git provides. There is not a single instance when you can't revert to an earlier version, however impossible or sticky the situation you may be in.

Opensource.com had a great set of articles regarding Git in 2021; I'm summarizing just the top 10. All the articles contain hacks, lesser-known facts, and tips and tricks that can come in handy while working with Git.
