Making Linux More Like Windows

  • Collabora's Work On Extending The Linux Kernel To Better Support Windows Gaming - Phoronix

    Windows gaming on Linux got some love this week at the Linux Foundation's Open-Source Summit Europe virtual event. In particular, a recap of the work that's been done so far on extending the Linux kernel to better support Wine / Steam Play based support for Windows games running on Linux.  Gabriel Krisman Bertazi as an engineer for consulting firm Collabora talked about their work in recent years on improving the Linux kernel for supporting Valve's needs around running Windows games on Linux with Steam Play. Collabora has been one of Valve's partners for this effort along with CodeWeavers and Valve employing various developers on improving the Linux graphics stack, etc. 

  • Collabora expect their Linux Kernel work for Windows game emulation in Kernel 5.11

    Collabora have been doing presentations during the Open Source Summit, with one particular talk from Gabriel Krisman Bertazi on the "State of Linux Gaming" being quite interesting. While there has been a lot of progress with the Windows compatibility layers Wine and Valve's fork Proton (part of Steam Play), there's still plenty of areas currently lacking and needing work. Collabora is one company extending the Linux Kernel to improve Linux gaming with these compatibility layers, thanks to Valve sponsoring the work. One of the big missing pieces of the pie is supporting the likes of anti-cheat and DRM, with anti-cheat especially causing all sorts of problems entirely breaking lots of Windows games in Wine and Proton. The State of Linux Gaming talk was mostly going over what anyone following would already know, as the event isn't aimed at your typical Linux gaming enthusiast. However, it was still an interesting talk to follow. Thanks to The Linux Foundation, I was able to attend and listen to the talk (the online event requires a ticket purchase) but I've been told by my Collabora contact that they will all eventually be up on their own YouTube Channel which could be as soon as early next week for anyone to be able to view. If you want a brief overview, you can find the slides here from the event schedule. One of the key points that Gabriel Krisman Bertazi went over is their work on system call emulation, which is now required because DRM and anti-cheat tech "are issuing system calls directly from the Windows game code and that bypasses Wine because Wine is not a sandbox" and Wine currently cannot capture those system calls needed which ends up causing games to crash.

  • Best Tools to Create a Bootable Linux USB Drive

    Unlike Windows, Linux distributions require a third-party tool to create a bootable USB. It is particularly handy with modern PCs which have done away with the old DVD-drives. Also, installation DVDs were quite delicate and would scratch or in worst-case scenarios, break apart under stress. This guide covers some of the best tools that you can use to create a bootable Linux USB drive.

  • 5 new sudo features you need to know in 2020 | Opensource.com

    When you want to perform an action on a POSIX system, one of the safest ways to do so is to use the sudo command. Unlike logging in as the root user and performing what could be a dangerous action, sudo grants any user designated as a "sudoer" by the sysadmin temporary permission to perform a normally restricted activity. This system has helped keep Linux, Unix, and macOS systems safe from silly mistakes and malicious attacks for decades, and it is the default administrative mechanism on all major Linux distributions today.

  • Arduino Blog » ESUB Tracks is a smart bicycle helmet with built-in electronics for enhanced safety

    Bike helmets can help minimize injuries in the event of an accident, but could a helmet also be used to help prevent a crash, or even enhance your riding experience? ESUB Tracks from WertelOberfell attempts to do both, featuring a variety of electronic enhancements which are powered by photovoltaic cells wrapped around its outer surface. ESUB Tracks includes a lighting arrangement on the back for turn signaling, triggered using voice commands to the helmet’s piezoelectric microphone. Additionally, it has a sensor to detect rapidly approaching vehicles from behind, warning the wearer of this condition via haptic feedback. Bone-conductive speakers are provided for listening to Bluetooth audio, and if all of that wasn’t enough, it even tightens down the straps when the buckle is fastened.

  • ESP32-S2 board targets battery-powered applications with 30uA deep sleep power consumption

    A few months ago, Olimex unveiled renders of ESP32-S2-Devkit-LiPo WiFi board that was supposed to consume as little as 2uA in sleep mode, follows ESP32-S2-Saola-1 board form factor and pinout, and adds an ultra-efficient circuitry to support LiPo batteries. The good news is that Olimex has now launched two versions of their ESP32-S2 board optimized for battery-powered applications with ESP32-S2-DevKit-Lipo and ESP32-S2-WROVER-DevKit-Lipo (with 2MB PSRAM) going for 5.56 Euros and 6.36 Euros respectively.

  • Testing PTFE Tube for 3D Printing

    Karl here. I’m back with a short article on some testing that I did on PTFE tube. When I received the Sovol SV02 3D printer it came with some baby blue replacement PTFE tube. It came preinstalled with the regular white stuff that most Bowden style printers come with. I have also been thinking about different ways to use the Retraction Calibration Tool I created.
