  • Contribute at the Fedora Test Week for Kernel 5.9 - Fedora Magazine

    The kernel team is working on final integration for kernel 5.9. This version was just recently released, and will arrive soon in Fedora. As a result, the Fedora kernel and QA teams have organized a test week from Monday, October 26, 2020 through Monday, November 02, 2020. Refer to the wiki page for links to the test images you’ll need to participate. Read below for details.

  • Linux Gets Fix For AMD Zen 3 CPU Frequency Handling Stemming From 8 Year Old Workaround - Phoronix

    Since 2012 there has been a quirk in the Linux kernel to disable/override using ACPI _PSD data on all AMD processors as a workaround in turn for Windows-specific behavior that clashes with the semantics of the Linux ACPI CPUFreq driver for CPU frequency scaling. With AMD Zen 3 this quirk is no longer needed to behave correctly and thus Linux 5.10 is going to drop this eight year old quirk on Zen 3 and newer.  The change since 2012 in the Linux kernel for AMD CPUs has overrode the ACPI _PSD table supplied by the BIOS. But now for Family 19h / Zen 3, the table accurately reports the P-state dependency of CPU cores. That correct table is needed for proper CPU frequency control with the new processors and thus the new kernel will stop overriding it so it can be used by ACPI CPUfreq for its frequency handling on the shiny new CPUs.

  • EXT4 Changes Land In Linux 5.10 With Fast Commits, Big Boost For Parallel Writes - Phoronix

    The EXT4 file-system updates have landed in Linux 5.10 with some notable additions for this mature file-system. [...] Another big change is the new EXT4 "fast commits" mode by Harshad Shirwadkar of Google. This fast commit mode is relevant for EXT4 users operated in ordered mode (the mount option data=ordered) and maintains a minimal delta for recreating the affected metadata in the fast commit space shared with the JBD2 journal. That can yield up to a ~103% write performance improvement in the ordered mode with fast commits enabled.  The EXT4 changes also include other fixes and low-level code improvements.

  • Linux 5.10 Has Initial Support For NVIDIA Orin, DeviceTree For Purism's Librem 5 - Phoronix

    Complementing the ARM(64) architecture changes for Linux 5.10 are now the SoC and board updates that are quite interesting this round.  The ARM platform/SoC support with Linux 5.10 ranges from initial bring-up of the NVIDIA Tegra Orin SoC to finally mainlining the DeviceTree support for the Purism Librem 5 smartphone revisions thus far to Raspberry Pi 4 display setup.

Games: Hive Time, Stadia and Retroarch

  • Developer of Hive Time reflects on the release and their pay what you want model

    Hive Time from developer 'Cheeseness' released nearly a year ago, and so the developer has written up a lengthy blog post on the development and the finances. A good read if you like behind the scenes dev info, here I will sum up a few interesting bits from it but the full article is definitely worth reading. It's a thoroughly interesting read because Hive Time is in quite a unique position. Not only because it's made with open source tools like Godot Engine, Blender, the GNU Image Manipulation Program, Inkscape, and Audacity it also released where you could download it for nothing. Technically, it's a $10 game but they made it pay what you want for people who can't afford to pay. The pay what you want model was made pretty popular years ago thanks to the likes of Humble Indie Bundle and others, but for selling a single game how does it turn out? That's what Cheese talks about and it seems to have been a tough sell overall.

  • Creative Director At Google Stadia Advocates Streamers Paying Game Devs And Publishers
           
             

    Way back in 2013, we discussed an interesting study conducted by Google looking at the effect of let's play and video game reviews has on the gaming industry. That study's conclusion was that viewers watched let's plays at a far higher clip than, say, video game trailers. Two-thirds of those views appeared to be watchers focusing on the video itself, whereas the other third were watching on secondary devices/screens in order to find tips and tricks for completing the game in question. Both were conducive to promoting the gaming industry, being a method for finding out if a game is worth buying and because gamers know they have a resource to help complete a game.

  • 4 Best Free Python-Based Content Management Systems - LinuxLinks

    A web content management system (WCMS) is software designed to simplify the publication of Web content. In particular, it enables content creators to submit content without requiring technical knowledge of HTML or the uploading of files. A CMS is most commonly used in creating an intranet or in establishing a presence on the Web. This type of software that keeps track of every piece of content on a Web site. Content can be simple text, photos, music, video, documents, or just about anything you can think of. A major advantage of using a CMS is that it requires almost no technical skill or knowledge to manage. Not only do content management systems help website users with content editing, they also take care of a lot of “behind the scenes” work such as automatically generating navigation elements, making content searchable and indexable, keeping track of users, their permissions and security setting, and much more. To provide an insight into the quality of software that is available, we have compiled a list of the best Python-based WCMS. They are all free and open source software. Here’s our recommendations.

  • 3 Open Source Python Shells - LinuxLinks

    Python is a high-level, general-purpose, structured, powerful, open source programming language that is used for a wide variety of programming tasks. It features a fully dynamic type system and automatic memory management, similar to that of Scheme, Ruby, Perl, and Tcl, avoiding many of the complexities and overheads of compiled languages. The language was created by Guido van Rossum in 1991, and continues to grow in popularity. Python is a very useful and popular computer language. One of the benefits of using an interpreted language such as Python is exploratory programming with its interactive shell. You can try out code without having to write a script. But there are limitations with the Python shell. Fortunately, there are some excellent alternative Python shells that extend on the basic shell. They each offer a good interactive Python experience.
