• Thoughts on The University of Minnesota Kernel Ban
• Some 5.12 development statistics — By the time the 5.12 kernel was finally released, some 13,015 non-merge changesets had been pulled into the mainline repository for this development cycle. That makes 5.12 the slowest development cycle since 5.6, which was released at the end of March 2020. Still, there was plenty of work done for 5.12.
• Linux 5.12 Release Announcement
• As Linux 5.12 released, Linus Torvalds warns next version will probably be rather large — "'Despite the extra week, this was actually a fairly small release overall. Judging by Linux-next, 5.13 will be making up for it."
• Flatpak 1.11.1 Brings Changes For Steam, Better Support For Command Line Programs — One of the changes with Flatpak 1.11.1 worth mentioning is allowing sub-sandboxes to have a different /usr and/or /app.
• steam-runtime-tools: pressure-vessel — pressure-vessel is a bit like a simplified version of Flatpak for Steam games.
• While we worry about WSLg Amazon is Positioned to Kill Server Linux
• Humble Bundle is removing their pay sliders and replacing them with two preset pay splits.
• Looking forward to Fedora 34 — In 2021, complaints about PulseAudio are scarce indeed; the quirks have long since been ironed out and, for most people, sound just works. Obviously, it must be time to rip out the audio infrastructure and start over. That is what Fedora has done in the 34 release; PulseAudio is gone, replaced by PipeWire.

A term like that may sound scary at first, but less technical users need not be wary. This change is simple to grasp, and will help many Workstation users in several key areas.

• Microsoft announces IPE, a new code integrity feature for Linux — Microsoft says that IPE is not intended for general-purpose computing. The IPE LSM was designed for very specific use cases where security is paramount, and administrators need to be in full control of what runs on their systems. Examples include embedded systems, such as network firewall devices running in a data center, or Linux servers running strict and immutable configurations and applications.

• Fedora 32 Looking At Using EarlyOOM By Default To Better Deal With Low Memory Situations — The oom-killer generally has a bad reputation among Linux users. This may be part of the reason Linux invokes it only when it has absolutely no other choice. It will swap out the desktop environment, drop the whole page cache and empty every buffer before it will ultimately kill a process. At least that's what I think that it will do. I have yet to be patient enough to wait for it, sitting in front of an unresponsive system.

• rfjakob/systembus-notify: systembus-notify - system bus notification daemon
• oomd — Out of memory killing has historically happened inside kernel space. On a memory overcommitted linux system, malloc(2) and friends usually never fail. However, if an application dereferences the returned pointer and the system has run out of physical memory, the linux kernel is forced to take extreme measures, up to and including killing processes. This is sometimes a slow and painful process because the kernel can spend an unbounded amount of time swapping in and out pages and evicting the page cache. Furthermore, configuring policy is not very flexible while being somewhat complicated.
• low-memory-monitor on GitLab
• low-memory-monitor — low-memory-monitor, as its name implies, monitors the amount of free physical memory on the system and will shoot off signals to interested user-space applications, usually session managers, or sandboxing helpers, when that memory runs low, making it possible for applications to shrink their memory footprints before it's too late either to recover a usable system, or avoid taking a performance hit.
