  • A New Kernel Patch Is Being Discussed That's Needed For Newer Windows Games On Wine

    Newer Windows games/applications are making use of system call instructions from the application code without resorting to the WinAPI and that is breaking Wine emulation support. A Linux kernel patch is now being worked on for addressing this issue in the form of system call isolation based on memory areas while having a smaller performance hit than alternatives.

    With newer Windows software executing system call instructions without going through the Windows API, Wine isn't able to intercept and emulate those system calls and thus breaking the support. Wine can't really rework its handling of every system call as that would thrash the performance. So a Linux kernel-based solution is being sorted out.

  • Cloud FTW: Steam on Chrome OS may not look like we thought

    Back in January, word got out that Google and Valve were collaborating to bring some form of native Steam client to Chrome OS. Director of Product Management Kan Liu told Android Police that the project would leverage Crostini, aka Linux on Chrome OS. Because I spend a good portion of my days tinkering with Linux on my Chromebook, I hastily presumed that Steam would be delivered in some sort of Chrome OS-optimized Linux package. While that could still be a possibility, it appears that Valve may look to the Clouds in Steam’s next evolution.

Linux Kernel gets an 'RFC' patch to help Windows games...

  • Linux Kernel gets an 'RFC' patch to help Windows games run in Wine

    A developer for Collabora, the open source consultancy firm that works with the likes of Valve has sent in a Linux Kernel patch aimed at helping Windows games run on Linux through Wine.

    From what's noted in the patch, which was sent in for gathering comments (RFC = Request for comments), it seems more and more modern Windows applications / games are sidestepping the actual Windows API. The result? It breaks Wine compatibility as "it doesn't have a chance to intercept and emulate these syscalls before they are submitted to Linux".

    What they're going for is an addition to the Linux Kernel, to enable them to filter and find out if the calls being done are from Wine itself or from the Windows application being run. They're proposing using the seccomp function, used usually for security purposes but this is in no way a security feature it's just how they're building the functionality for Wine while re-using what's available.

  • 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.
