  • Towertale, a story-driven 2D action game with a focus on big boss battles is coming to Linux

    With some absolutely insane looking action sequences, Towertale just recently released and they're planning to support Linux.

  • Valve add additional titles to the Steam Play Whitelist

    After recently pushing out a pretty big update to Steam Play with Proton 4.11, Valve have now added some additional titles to their Whitelist.

    What is the Whitelist? Currently, this is the list Valve have accepted to be shown as a game you can install in the Linux Steam client, without enabling Steam Play on your entire library. They are also set to a specific version of Proton by Valve, to hopefully give the best experience.

  • Gunslugs:Rogue Tactics, the tactical action-platformer confirmed for release on August 6th

    Possible one of the most interesting action-platformer games I've seen in a while, Gunslugs:Rogue Tactics is launching on August 6th.

    I'm a big fan (understatement) of games like Broforce, which focus heavily on over-the-top action and a lot of platformers simply go along and follow that design. This is why Gunslugs:Rogue Tactics has my attention, it doesn't seem like yet another platformer. Not only does it have some random generation, to keep things from feeling stale, it has a focus on tactical decision making and stealth on top of some ridiculous looking action of course.

  • Counter-Strike: Global Offensive adds new maps and a "Scrimmage" game mode

    Valve have updated Counter-Strike: Global Offensive to introduce some new maps as well as mix up competitive play with a new "Scrimmage" game mode.

    The Workout map has been removed, with Breach and Seaside making an appearance in Defusal Group Sigma. Breach, Seaside and Ruby have also been added as new "Scrimmage Maps" to official competitive matchmaking.

RISC-V gains new performance leader with Alibaba’s 16-core XT 910

Filed under
Linux

Alibaba announced a 16-core XuanTie 910 RISC-V CPU with a 7.1/MHz CoreMark score. RISC-V continues to expand quickly in China, accelerated by U.S. tariffs, but Arm is fighting back with “Arm Flexible Access” licensing.

Chinese Internet retail and tech giant Alibaba Group has announced its first processor and the most powerful design based on the open source RISC-V IP yet. First reported by Nikkei Asian Review, the XuanTie 910 (also called the XT 910 or T-Head), is a 16-core, 2.5GHz design.

Taking Stock of Librem 14

Like many hardware companies, Purism has taken a “Just In Time” manufacturing approach for our products including the Librem laptop line. That means that we make a bit more of a product than we think we need, and schedule the next manufacturing run so that the product arrives in our warehouse “just in time” for us to deplete the previous manufacturing run. In an ideal world that means we never run out of stock, but also never have massive inventories taking up space in our warehouse. Also like many hardware companies the supply chain woes of the last two years have caused us to rethink this approach. Each time it seemed like we had made enough Librem 14s to catch up to current and projected orders, delays of one kind or another created a new backlog as new orders continued to come in. We’ve decided to scrap “Just in Time” in favor of manufacturing far more Librem 14s than we currently need, and will have our shelves full of Librem 14 stock by the end of the year. Read more

Chrome OS 98 adds management of multiple Chromebook Linux containers

Earlier this month I reported that Chrome OS was adding multiple container management to Chromebook. The last Dev Channel update has finally brought the first iteration of that feature and I do have it working. At the moment, however, I’ve only been able to add a second Linux container for Debian. Regardless, here’s how Chrome OS 98 adds management of multiple Chromebook Linux containers. For starters, I had to enable the following experimental flag in Chrome OS 98: chrome://flags#crostini-multi-container and restart my browser. After that, I saw the new “manage extra containers” option in my Linux settings: Chrome OS 98 multiple Chromebook Linux containers management Choosing this option brought me to the following screen, which initially had a single container, as expected. Here I could change the color of each one. I clicked the Create button, added a second Debian container, and left it the default color. The three-dot option offers ways to stop or delete a container.

Kernel: IO_uring, AMD, Intel, and Analog Devices

  • IO_uring Network Zero-Copy Send Is Boasting Mighty Speed-Ups - Phoronix

    Early patches providing for IO_uring zero-copy send support for the Linux kernel's networking subsystem is looking extremely promising for greater throughput. Developer Pavel Begunkov posted the set of twelve patches today working on this zero-copy send support for IO_uring with the networking subsystem. These initial patches are marked as a "request for comments" as some items are still being sorted out with the code.

  • AMD-Pstate Driver Updated A 5th Time For Improving Ryzen Power Efficiency On Linux - Phoronix

    Sent out today was the fifth revision to AMD's new "amd-pstate" kernel driver focused on providing enhanced CPU frequency controls for Linux systems. AMD's P-State driver remains under active development for improving the Linux power efficiency for Ryzen (and EPYC) processors. AMD P-State makes use of ACPI CPPC for more informed and finer-grained frequency controls on modern (Zen 2 and newer) processors compared to what is afforded by the existing ACPI CPUFreq frequency scaling driver currently used by AMD Linux systems.

  • Intel Posts Linux Patches Bringing Up Alder Lake N Graphics - Phoronix

    With the graphics driver support for Alder Lake S-series in good shape with Linux 5.16 and the Alder Lake P-series support also coming together for upcoming ADL-based laptops, next up is the Alder Lake N enablement happening for Linux. Alder Lake N for low-end, low-power hardware is now coming together. Though over the existing ADL-S and ADL-P Linux support, it's basically adding in new PCI IDs for ADL-N.

More about those zero-dot users

Yesterday’s article about KDE’s target users generated some interesting discussions about the zero-dot users. One of the most insightful comments I read was that nobody can really target zero-dot users because they operate based on memorization and habit, learning a series of cause-effect relationships: “I click/touch this picture/button, then something useful happens”–even with their smartphones! So even if GNOME and ElementaryOS might be simpler, that doesn’t really matter because it’s not much harder to memorize a random-seeming sequence of clicks or taps in a poor user interface than it is in a good one. I think there’s a lot of truth to this perspective. We have all known zero-dot users who became quite proficient at specific tasks; maybe they learned how to to everything they needed in MS Office, Outlook, or even Photoshop. The key detail is that these folks rely on the visual appearance and structure of the software remaining the same. When the software’s user interface changes–even for the better–they lose critical visual cues and reference points and they can’t find anything anymore. Read more
