• SUSE Linux Enterprise 15 SP4 Released - Switches To NVIDIA’s Open Kernel Driver — Notable with SLE 15 SP4, SUSE is already switching to using NVIDIA's open-source GPU kernel-mode driver that NVIDIA open-sourced last month

• Element Call Beta 2 includes lots of exciting new updates! — In a walkie-talkie call, videos are disabled, and everyone is muted by default. To speak, press the ‘push-to-talk’ (PTT) button, either by pressing it on the screen or by holding the spacebar. The catch is that, just like a walkie-talkie or two-way radio, only one person can speak at a time. When someone else is speaking, your PTT button will be disabled, and if you try to push it you’ll hear a warning beep.
• Fedora and Ubuntu EOL announcements — If you are running Fedora 34, the time has come to move on; that distribution will reach the end of its support life on June 7. Users of Ubuntu 21.10 have a little longer, but that release loses support on July 14 and users should update to 22.04.

• Apple will allow Linux VMs to run Intel apps with Rosetta in macOS Ventura — You can even use Rosetta with non-Apple Arm CPUs, though you probably shouldn't.
• Running Intel Binaries in Linux VMs with Rosetta
• Hector Martin on Twitter — “Huh, so Rosetta is now a Linux app. Without Linux kernel patches this can’t use any special M1 features, so if this runs significantly better than FOSS offerings that should help dispel the myth that “the M1 has magic make-Rosetta-fast features”.
• Longhorn on Twitter — Well. Rosetta 2 needs a quite recent CPU (post v8.2) to work because of the instructions used. Does it work on non-Apple arm64 CPUs? 🤔 Yes. (allows to settle the argument once and for all that this needs anything Apple specific outside of TSO support*. Answer is a no.)

Plus a major step in Apple M1 GPU support.

• Intentionally buggy commits for fame—and papers [LWN.net] — A buggy patch posted to the linux-kernel mailing list in early April was apparently the last straw for Greg Kroah-Hartman as it led to the planned reversion of a whole slew of commits with one thing in common: their origin at the University of Minnesota (UMN).
• An open letter to the Linux community [LWN.net] — We sincerely apologize for any harm our research group did to the Linux kernel community. Our goal was to identify issues with the patching process and ways to address them, and we are very sorry that the method used in the “hypocrite commits” paper was inappropriate.
