EasyOS Dunfell 2.6.1 released for the Raspberry Pi4
The very first release of EasyOS Dunfell-series for the Raspberry Pi4 was version 2.6, released on January 19. See announcement:
https://bkhome.org/news/202101/easyos-dunfell-26-released-for-the-raspberry-pi4.html
Since then, some package version bumps: SeaMonkey is now version 2.53.6 and includes the IRC chat module, ffmpeg is 4.3.1. LibreOffice is still a somewhat old version, 7.0.1.2, but I recompiled it with PDF-import support, which seemed like a good thing to have.
Version 2.6.1 also has Samba, which had been left out of 2.6. Also added package 'smbnetfs'. Oh yes, also added package 'tigervnc', that Forum member rufwoof reported as very fast. Added package 'libvdpau-va-gl' though don't really know why.
There were some performance issues with 2.6, that have mostly been fixed. SeaMonkey was often temporarily freezing, which seems to have been fixed by changing to 'kyber' IO scheduling. Plugging in a USB-stick, the kernel now consistently recognizes it first go -- due to version bump of the kernel from 5.10.4 to 5.10.9 and update of the device-tree. -
Build a programmable light display on Raspberry Pi | Opensource.com
This past holiday season, I decided to add some extra joy to our house by setting up a DIY light display. I used a Raspberry Pi, a programmable light string, and Python.
[...]
Each light can be individually programmed using an RGB set of integers or hex equivalents. These lights can be packaged together into matrices, strings, and other form factors, and they can be programmatically accessed using a data structure that makes sense for the form factor. The light strings I use are addressed using a standard Python list. Adafruit has a great tutorial on wiring and controlling your lights.
[...]
The neopixel_controller Flask application, in the neopix_controller directory of the github repository (see below), offers a front-end browser graphical user interface (GUI) to control the lights. My raspberry pi connects to my wifi, and is accessible at raspberrypi.local. To access the GUI in a browser, go to http://raspberrypi.local:5000. Alternatively, you can use ping to find the IP address of raspberrypi.local, and use it as the hostname, which is useful if you have multiple raspberry pi devices connected to your wifi.

Red Hat/Fedora Leftovers
| The Innovation Lab: A Space for Creative Learning
The reason why we use System76 to power all the computers in the space is because I’m a big supporter of Linux in general, and System76 has been really consistent and helpful. I think the openness of System76 definitely gives the students the ability to experiment and the freedom to break stuff in a creative environment, without being too constrained by proprietary software.
