  • How To Install Apache Kafka on Debian 10 - idroot

    In this tutorial, we will show you how to install Apache Kafka on Debian 10. For those of you who didn’t know, Apache Kafka is an open-source distributed event streaming platform used by thousands of companies for high-performance data pipelines, streaming analytics, data integration, and mission-critical applications.

    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 through the step-by-step installation of the Apache Kafka on a Debian 10 (Buster).

  • Baserow: Create and manage databases with this no-code free app

    Creating and managing databases is a critical part for any business or any development process. It also requires fair knowledge of installing, configuring and managing database engines and the managing software.

    While there are some cool management tools like PhpMyAdmin (Adminer) and pgAdmn for PostgreSQL, they also require technical skills to install, run and manage. Furthermore, they are not easy to use by normal users.

  • Enabling Linux for your managed Chromebooks

    The Linux container on Chrome OS still feels a bit “Beta” in my opinion but it does offer up some useful additions to the Chromebook toolbox. Apart from giving you a new set of productivity tools, the terminal is a great way to learn your way around the Linux command-line interface. Whether you’re teaching a class on Linux how-to or using the Debian-based container for serious development, Crostini is disabled by default on managed Chrome OS devices and you’ll need access to an IT admin or the Admin Console to enable it.

    If you manage a large fleet of Chrome devices and users, some of this may seem elementary to you and I applaud you for learning the mysterious ways of the Google Admin Console. Should you find yourself new to managed users and devices, you might be fumbling around the Admin Console looking for a way to enable the Linux container for your fleet of managed Chromebooks. Don’t feel bad. The main reason I’m writing this article is that I found myself doing the exact same thing. No worries. Enabling Linux for your users is quite simple once you know where to look. So, let’s get to it.

  • [Older] Tuning the TCP stack in Ubuntu Operating System - Linux Concept

    Transmission Control Protocol and Internet Protocol (TCP/IP) is a standard set of protocols used by every network-enabled device. TCP/IP defines the standards to communicate over a network. TCP/IP is a set of protocols and is divided in two parts: TCP and IP. IP defines the rules for IP addressing and routing packets over network and provides an identity IP address to each host on the network. TCP deals with the interconnection between two hosts and enables them to exchange data over network. TCP is a connection-oriented protocol and controls the ordering of packets, retransmission, error detection, and other reliability tasks.

  • Please Stop Closing Forums And Moving People To Discord

    A few days ago Eurogamer closed their forums, bringing to an end over 20 years of community discussion. The site explained the move like sites and companies always do (only a few are still using them), and it made sense the way it always does (that’s a lot of money for not much gain), but that doesn’t mean the process itself isn’t something that sucks.

  • Nokia has recommenced participation in the O-RAN Alliance

    The O-RAN Alliance said it became aware of concerns regarding some participants that may be subject to U.S. export regulations, and has been working with O-RAN participants to address these concerns. The O-RAN Board has approved changes to O-RAN participation documents and procedures. While it is up to each O-RAN participant to make their own evaluation of these changes, O-RAN is optimistic that the changes will address the concerns and facilitate O-RAN’s mission, the Alliance said.

Red Hat/Fedora Leftovers

  • 5 DevSecOps myths, explained

    New ways of doing things tend to beget new myths and misunderstandings about those emerging methods. A common example: As newer work processes and cultures get popularized, people commonly begin to tout a single correct way to implement them. In all likelihood, though, there’s more than one “right” way to do it – and that’s true for DevSecOps, as it was with DevOps before it. Demystifying DevSecOps, then, is actually a meaningful (if not wholly necessary in some organizations) step toward a successful implementation. That’s because DevSecOps, like DevOps, is as much a matter of people and culture as anything else. As Red Hat associate principal solutions architect Mike Calizo wrote over at opensource.com, “DevSecOps encourages security practitioners to adapt and change their old existing security processes and procedures. This may sound easy, but changing processes, behavior, and culture is always difficult, especially in large environments.”

  • Red Hat's Upstream Contributions Are Making For A Great Fedora Workstation 35 - Phoronix

    Fedora Workstation 35 will hopefully be out at the end of October (currently the beta is running behind schedule) and when it does ship it's once again at the bleeding-edge of Linux features. Fedora Workstation 35 is shaping up to be another great release for those interested in a feature-rich desktop experience. Fedora Workstation 35 test builds have been working out great on the few systems I've tried so far in the lab. More Fedora Workstation 35 testing and benchmarks will be coming up in the weeks ahead. In anticipation of the upcoming Fedora 35 Beta, Red Hat's Christian Schaller once again published a new blog post outlining some of the big changes on the Fedora Workstation side for this six-month update.

Writing OpenType shaping rules for advanced (complex) scripts is harder. Writing OpenType shaping rules without causing any undesired ligature formations is even harder.

  • Laser Chess game Deflection is out now providing a fun new strategy game | GamingOnLinux

    Take down the enemy King with a great big laser, that's the aim of the game in Deflection. It's basically the original Laser Chess updated for modern platforms by Coreffect Interactive. A simple idea with you moving mirrors around that can bounce the laser, while also having different sides that are vulnerable to the enemy laser. Positioning and thinking ahead are the key to victory here and Coreffect Interactive have clearly put a lot of thought into it. It's another case of a game that's real easy to get into and understand, however becoming good at it is a whole different thing. It's more than that though as there's a few different pieces you get to use like portals to move the laser around and a disrupter to weaken pieces close to it too.

  • Free and open source flight sim FlightGear is working on VR support | GamingOnLinux

    It's currently at a stage where they consider it highly experimental, more of a proof-of-concept but if they get it all hooked up properly it could help aid other developers too since it's FOSS.

  • Open source dungeon builder KeeperRL adds a Dwarves faction in the latest big release | GamingOnLinux

Over 7 years of development has gone into this game so far and it just keeps getting better. Alpha 33 adds in not just a whole new faction but it also overhauls some existing systems. Some of what's new includes a special storage system with custom storage furniture for various equipment types, a new fog effect, new z-level enemies with progressing difficulty, crossbows got added, a reworked flanking/parry mechanic with visual indicators and hints, combat experience is now based on the number of unique kills, a new 'swamp' biome for some villains that was officially added from a mod, fast travel between z-levels in the turned-based mode and so much more. There's even a new intro.

  • Call of Saregnar is a nod to 90s party-based RPGs and it's on the way to Linux | GamingOnLinux

    Do you miss earlier party-based RPGs? Call of Saregnar is an in development title from Damjan Mozetič inspired by the likes of Betrayal at Krondor, TES: Daggerfall and Realms of Arkania. The developer explains that it's a game of exploration and investigation with an emphasis on story and characters, and that it "proudly ditches the cliches of the RPG genre and expects you to think". What makes it real interesting is that it blends together a low-poly 3D style with the characters made from shots of real-life actors. [...] On the status of Linux support, the developer made it clear on Twitter that it's already hooked up.
