System 76 retort
https://blog.system76.com/post/667593198841069568/open-up-contributions-and-collaborations

After that whiney GNOME post, System76 responds with details to what exactly they have contributed back upstream.
Because GNOME needed a proverbial slap across the face after that.
System76 does amazing work for the Linux community, from their contributions to GTK, to Rust, to Nvidia, to open firmware, to Coreboot all the way to the Linux Kernel itself.
And, one of the most important contributions System76 has made, is that they have grown the Linux community!

Pine64 updates
https://www.pine64.org/2021/11/15/november-update-first-impressions/

Developer devices are going out soon, the pre-orders have been terminated because as it turns out people like what Pine is selling.
A feature many people have requested for the PineTime, with the just released InfiniTime 1.7.0, now you can set the date and time without having to use the companion app!
And there is step-count syncing from the PineTime to the Amazefish app on Linux.
The PinePhone (Pro) keyboard is neat.
That will give you a portable little Linux machine on the cheap.
Step data is now being tracked on the Pine Time so Pedro can work on minimizing his steps per day.
A reminder that SOQuartz is a thing and comes in 8GB variants.

5.16 rc1
https://www.theregister.com/2021/11/15/linux_5_16_rc1/

Linux Kernel 5.16 release candidate 1 is out, with a very important memory management update, as well as more hardware support.
5.16 will introduce “Memory Folios”, which is a memory management system that
- “aims “to allow filesystems and the page cache to manage memory in larger chunks than PAGE_SIZE”.
- And has been shown to improve workloads, such as building the kernel, of up to a 10% performance increase.
Looking forward to even more hardware support in the upcoming final release, including:
- Mainline support for the Raspberry Pi 4 Compute Module.
- More Apple M1 support.
- RISC-V hypervisor support for KVM.
And this is so cool, there are m68k updates, which means more support for Linux on my vintage computer hardware:
- My Atari computers, Amiga and some of my Macs :-D
Improving memory management will create some nice waves of performance improvement down the line.
This has some of the moon code Tak worked up for the MOTU MK3 series.
I’m sticking with 5.10 until all the audio gremlins are worked out.

Penpot

SVG by default, is someone taking a crack at inkscape with a better modern UI?
A UX/UI web based collaboration tool that is not only open source, and uses SVG, but is platform independent.
It is a great tool for visual designers and developers.

OBS first time setup
https://linuxgamecast.com/2021/11/first-time-setup-obs-linux-basics/

If you’ve ever wanted to OBS on Linux this might be of use.
It should get you started with setting up an interface, microphone, and webcam.
Basic game capture.
Basic overlays.

Slice of Pi

RasPi OS on Debian 11

https://www.raspberrypi.com/news/raspberry-pi-os-debian-bullseye/

A new version of the Raspberry Pi OS is here with lots of major changes, and it is now based on Debian 11 “Bullseye”.
The desktop and applications have switched to the GTK+3 user interface toolkit, which will create a cleaner look and feel.
Another major change is that the RPi OS has a new compositing window manager, mutter, which replaces the openbox window manager from previous releases.
And more window effects, such as animations and shading, are now possible, as well as being Wayland compatible for the future.
But because mutter uses more system resources, if you don’t have a Pi with at least 2GB or more of RAM, the older openbox window manager will still be used.
There is a new notification manager in the taskbar like other Linux OSs.
And a new updater plugin that utilizes the new notification system, which provides a graphical way to install updates without needing to use a terminal window.
Thar be dragons.
The switch to libcamera, while a good thing has caused a few projects to reworks things.
Lots of updates for the desktop.
I know it can do light desktop things but I still view the Pi as a headless device.
GTK3 and mutter, because the Pi is well known for its massive powerhouse of a CPU/GPU combo.
