  • OSS+ELC show returns live with RISC-V, AI, Martian rovers, and 30 years of Tux

    The Linux Foundation has posted a schedule for its Open Source Summit + Embedded Linux Conference, to be held (live this time) on Sep. 27 to Oct. 1 in Seattle. RISC-V is a big topic, and there is a keynote on the Martian Perseverance rover and Ingenuity helicopter.

    [...]

    Linus Torvalds and VMware’s Dirk Hohndel will have their usual free-wheeling chat. No doubt, they will touch on the 30th anniversary of Torvalds’ release of Linux, which the LF is celebrating with a T-shirt design contest. Attendees can pick up the winning design. There are also keynotes from speakers representing the Linux Foundation, Google, IBM, SUSE, Red Hat, and Thistle Technologies.

    Even if you don’t plan to travel to Seattle or watch the videos afterward, the presentation listings provide an interesting snapshot of embedded Linux and open source topics. This year’s program has a heavy dose of RISC-V, diversity issues, and best practices for open source.

  • This Arduino-powered robotic fish swims like the real thing | Arduino Blog

    Biomimicry is often used to take the designs that nature has perfected over a period of millions of years and incorporate them into our own technology. One maker who goes by mcp on YouTube took this idea one step further and created a fish that can swim in the water like the actual creature. By carefully analyzing and studying the patterns a fish makes while it scurries through a lake, he was able to reduce these motions down to just a few joints.

    The body of this DIY robotic fish was constructed from a series of four joints that each contain a single mini servo motor to control their movements. Next, an Arduino Nano was selected as the microcontroller board due to its small size and ample amounts of GPIO pins. In order for the fish to sense if there is an obstacle in the way and avoid it, the device also features “eyes” that utilize IR emitter/receiver pairs.

  • Meet your new table tennis coach, a tinyML-powered paddle!

    Shortly after the COVID-19 pandemic began, Samuel Alexander and his housemates purchased a ping pong set and began to play — a lot. Becoming quite good at the game, Alexander realized that his style was not consistent with how more professional table tennis players hit the ball, as he simply taught himself without a coach. Because of this, he was inspired to create a smart paddle that uses an integrated IMU to intelligently classify which moves he makes and correct his form to improve it over time.

    Alexander went with the Nano 33 BLE Sense board due to its ease of use and tight integration with TensorFlow Lite Micro, not to mention the onboard 6DOF accelerometer/ gyroscope module. He began by designing a small cap that fits over the bottom of a paddle’s handle and contains all the electronics and battery circuitry. With the hardware completed, it was time to get started with the software.

Games: Steam Deck, FUTEX2, and Anti-Cheat Support

  • Steam Deck, Linux and Mac Get Easy Anti-Cheat Support

    Epic Games has just released an update to its Easy Anti-Cheat software that will add support for the Steam Deck, as well as Linux and macOS operating systems. According to an Epic blog post today, the new update is now available to developers for free and is designed to work with Wine and Steam's Proton compatibility layer to ensure all platforms under Linux get full anti-cheat support. This is great news for Linux Gamers and for the new Steam Deck, since the anti-cheat services were previously locked to Windows operating systems. Even though the games could be fully functional in a compatibility environment such as Proton or Wine. Now, more platforms have the capability to run all multiplayer games with Epic's popular anti-cheat software, as long as developers enable Linux and Mac support. This is especially important for Valve's Steam Deck, which counts on its SteamOS being able to run the entire Steam library. Obviously, lacking anti-cheat support could have been a major problem for the new console.

  • Valve's Steam Deck supports dual boot and booting from a microSD card - Liliputing

    The Valve Steam Deck is expected to begin shipping in December to customers who pre-orders the handheld gaming computer for $399 or more. But ever since introducing the Linux-powered PC with a custom AMD processor this summer, Valve has been getting a lot of questions.

  • Updated "FUTEX2" futex_waitv Patches Posted To Address Latest Feedback - Phoronix

    The promising FUTEX2 work focused on improving the Linux performance for running Windows games via Wine/Proton by extending futex to wait on multiple locks is still moving forward. Last month the work was revised in simpler form by just focusing on the new "futex_waitv" system call and postpone additional improvements planned around variable-sized futexes, NUMA-awareness, and more. That additional work will come later while the immediate focus is on the "futex_waitv" system call to address the needs of Wine/Proton by better matching Windows' WaitForMultipleObjects behavior with more efficient emulation.

  • Epic Games Announces Easy Anti-Cheat For Linux - Including Wine/Proton - Phoronix

    Not too surprising given the Steam Deck is inching closer towards release and we've known Valve has been working to improve the anti-cheat situation for games on Linux, but today EAC owner Epic Games officially announced Easy Anti-Cheat for both Linux and macOS. Easy Anti-Cheat is one of the popular anti-cheating solutions used by a number of Windows games. Epic Games is now making EAC available for Linux and macOS. Plus they are also making it supported under Wine/Proton too.

  • Epic Games announce full Easy Anti-Cheat support for Linux including Wine & Proton | GamingOnLinux

    Today, Easy Anti-Cheat from Epic Games / Epic Online Services has officially announced a full expansion for Linux including native builds and Wine + Proton. This is big for Linux Gaming and the Steam Deck. For those who don't know, Epic Games owns Easy Anti-Cheat and earlier this year they made it free for all developers making Windows games. Today this has been expanded to fully support developers doing native Linux games (and macOS too). Not only that, this is the big one we've been waiting for — they've also expanded Easy Anti-Cheat support officially for the Wine and Steam Play Proton compatibility layers.

  • Epic Games makes Easy Anti Cheat available for Linux, paving the way for Steam Deck | Windows Central

    One of the big flies in the Steam Deck ointment has always been how anti-cheat software will be handled. The truth is that a lot of the popular Windows games that can't be played on Linux through Steam's Proton Compatibility layer, or through WINE, are because of anti-cheat software. The first big step forward has just happened, though, right as game developers are starting to receive their Steam Deck dev kits. Epic Games, owner of Easy Anti Cheat, has announced that the software is now compatible with Linux, including WINE and Proton, as well as macOS. And all for the low price of free.
