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.

  • 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.

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.

  • How to Install Tor Browser on Fedora 34 - LinuxCapable

    or, also known as The Onion Router, is open-source, free software that enables anonymous communication when using online services such as web surfing. The Tor network directs the Internet traffic through a free worldwide volunteer overlay network with over six thousand relays and continues to grow. Many users want to find more ways to keep their information and activities anonymous or at least as private as possible, which has led to Tor Browser growing quite popular in recent years as it conceals a user’s location and usage from anyone conducting network surveillance or traffic analysis. The Tor network is intended to protect the personal privacy of users and their freedom and ability from conducting communication without having their activities monitored, and data were taken without their consent and used to sum it up. In the following tutorial, you will learn how to install the latest Tor Browser on Fedora 34.

The Wine AppDB is a database containing a list of applications that have been tested and confirmed to work under Wine.

  • Monitoring for process completion in 2021 – Ariadne's Space

    A historical defect in the ifupdown suite has been the lack of proper supervision of processes run by the system in order to bring up and down interfaces. Specifically, it is possible in historical ifupdown for a process to hang forever, at which point the system will fail to finish configuring interfaces. As interface configuration is part of the boot process, this means that the boot process can potentially hang forever and fail to complete. Accordingly, we have introduced correct supervision of processes run by ifupdown-ng in the upcoming version 0.12, with a 5 minute timeout. Because ifupdown-ng is intended to be portable, we had to implement two versions of the process completion monitoring routine. The portable version is a busy loop, which sleeps for 50 milliseconds between iteration, and the non-portable version uses Linux processor descriptors, a feature introduced in Linux 5.3. For earlier versions, ifupdown-ng will downgrade to using the portable implementation. There are also a couple of other ways that one can monitor for process completion using notifications, but they were not appropriate for the ifupdown-ng design.

  • How to Install Let's Encrypt SSL for NGINX on Rocky Linux 8

    Security is one of the top-of-mind concerns for website owners, more especially, if you are running an eCommerce store or a site that accepts users’ confidential information such as usernames and passwords. The plain HTTP protocol is insecure as data is sent in plain text and hackers can eavesdrop on the communication sent to and from the web server. To overcome this risk, it’s recommended to secure a web server using a TLS/SSL certificate. This is a cryptographic digital certificate that encrypts your web server and ensures data exchanged with the webserver is encrypted. Let’s Encrypt SSL certificate is a digital certificate provided by Let’s Encrypt CA ( Certificate Authority) to secure a web server. It’s a free TLS/SSL certificate that is valid for only 90 days, whereupon renewal is required before expiry. It’s beneficial for startups or individuals who cannot afford a premium SSL certificate for their blogs or websites. In this guide, we will demonstrate how you can install the Let’s Encrypt SSL/TLS certificate for NGINX on Rocky Linux 8

  • Watch Logs in Real Time in Linux With Tail, Less & Multitail

Tail is the most popular command for this purpose but there are some other tools as well. I'll show them to you in this tutorial.

Arcan as Operating System Design

Time to continue to explain what Arcan actually “is” on a higher level. Previous articles have invited the comparison to Xorg ( part1, part2 ). Another possibility would have been Plan9, but Xorg was also a better fit also for the next (and last) article in this series. To start with a grand statement: Arcan is a single-user, user-facing, networked overlay operating system. With “single-user, user-facing” I mean that you are the core concern; it is about providing you with controls. There is no compromise made to “serve” a large number of concurrent users, to route and filter the most traffic, or to store and access data the fastest anywhere on earth. With “overlay operating system” I mean that it is built from user-facing components. Arcan takes whatever you have access to and expands from there. It is not hinged on the life and death of neither the Linux kernel, the BSD ones or any other for that matter. Instead it is a vagabond that will move to whatever ecosystem you can develop and run programs on, even if that means being walled inside an app store somewhere. Read more
