  • Using SS to monitor connections in GNU/Linux for new users

    The ever popular Netstat tool, has been depricated for quite a few years now, and newer tools have been developed for the command line to replace it; namely, ss.

    Using ss is extremely simple, given the power behind the command, and the amount of information you can obtain while using it, such as information for TCP, UDP, PACKET, RAW, DCCP and UNIX Sockets.

  • Pidgin 2.13 Linux Desktop Instant Messaging Client Released

    Desktop-based instant messaging clients are becoming increasingly rare in the age of mobile apps and browser-based alternatives, but Pidgin formerly known as GAIM continues moving along albeit slowly. Recently the Pidgin 2.13.0 release happened without much attention.

    Pidgin 2.13 was released back in March with a number of bug fixes, better support for dark themes, improved transparency handling, API updates, and more but it was mostly just about fixing a number of bugs. Pidgin 2.13.0 had been the first update in one year since Pidgin 2.12.

  • kTLS in Cubemap

    Cubemap, my video reflector, is getting TLS support. This isn't really because I think Cubemap video is very privacy-sensitive (although I suppose it does protect it against any meddling ISP middleboxes that would want to transcode the video), but putting non-TLS video on TLS pages is getting increasingly frowned upon by browsers—it used to provoke mixed content warnings, but now, it's usually just blocked outright.

    This took longer than one would expect, since Cubemap prides itself on extremely high performance. (Even when it was written, five years ago, it could sustain multiple 10gig links on a single, old quadcore.) Cubemap is different from regular HTTP servers in that it doesn't really care about small requests; it doesn't do HLS or MPEG-DASH (although HLS support is also on its way!), just a single very long stream of video, so startup time doesn't matter at all. To that extent, it uses sendfile() (from a buffer file, usually on tmpfs or similar), which wasn't compatible with TLS… until now.

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.
