LWDW 381: GoXLR on Linux, Rocky Red Hats, and dot matrix trucks?

Rocky and Alma react to the changes at Red Hat, Linux kernel 6.4 gets a P-State driver extension for AMD, GoXLR on Linux nears 1.0, and a pi-powered truck printer.

Last week Red Hat tossed a wrench into the system.
Red Hat will now only be releasing the source code for RHEL RPMs behind their customer portal.
A lot of people learned that the GPL allows that.
Rocky remains confident they will be able to continue providing a bug-for-bug compatible and freely available alternative to Red Hat Enterprise Linux (RHEL), despite changes in accessibility.
They have come up with a way that abides by the licensing agreements but it’s a lot of manual work.
Alma plans to continue but has not shared a roadmap.
As I have been doing research since this announcement by Red Hat, I realised that SUSE does subscriptions behind a customer portal too.
And Ubuntu Pro sources are not available to non-Pro customers.
So Red Hat is playing catch up.
The power of open source and its active community keeps the penguins marching on.
The free Red Hat Developer Subscription for Individuals is available to individuals, not organizations or teams, and is designed for personal servers, home labs, and small open source communities.
Am I happy with this move? No, I’m not… but I get it.

Linux Kernel 6.4

https://www.debugpoint.com/linux-kernel-6-4/

Linus Torvalds announced the release of Linux Kernel 6.4 on Sunday.
And there are lots of updates and hardware enhancements for AMD and Intel CPUs, GPUs, and Arm SoCs in this latest Linux Kernel 6.4 release!
Initial support for Apple M2 SoC which is used in the current MacBook Air, MacBook Pro, and Mac Mini systems.
And Wi-Fi support for Apple M1 Pro/Max devices.
AMD’s P-State driver extension, Guided Autonomous Mode, has been submitted to the Linux 6.4 kernel which will likely improve performance and power efficiency for AMD Ryzen and EPYC servers.
Linux 6.4 includes new power features for the Steam Deck via the updated AMDGPU kernel driver.
New Wi-Fi drivers for Realtek rtl8710bu, rtl8822bs, rtl8822cs & rtl8821cs.
And support for the Logitech G935 wireless 7.1 surround sound gaming headphones, which I love and use.
Rumble support for the latest Xbox controllers.
Support for the Lenovo Yoga Book X90F 2-in-1 tablet.
And new drivers for the ROG STRIX Z390-F GAMING motherboard.

GoXLR

https://github.com/GoXLR-on-Linux/goxlr-utility/releases/tag/v0.12.0

Huge fan of reverse engineering and these lads are on it.
The GoXLR App replacement for Linux, Windows and MacOS is exactly that.
A tool to configure and control a TC-Helicon GoXLR or GoXLR Mini on Linux.
The latest release brings a few notable fixes.
- EQ Fine Tune is finally available in the UI
- UI now has a basic visualisation of the device
- Option to allow remote network access in the UI
- And better sample handling.
This is the largest ChangeLog to date.
Getting ready for a feature-freeze for the 1.0 release.
Added an option to allow remote network access to the daemon via System Settings.
A LinuxGameCast shout-out too, thank you devs!

Slice of Pi

Truck Dot Matrix

You have seen planes writing giant messages in the sky.
How about instead of skywriting, road writing?
Well a developer named Ryder Damen has somehow managed to create a giant dot matrix printer on land using his truck and a Raspberry Pi!
The printing process works by dropping splotches of water onto the road while the truck is driven.
The water is dropped carefully to shape letters and form custom messages.
Ryder uses a web interface in the cab of the truck which controls a series of hoses and valves.
Solenoids are used to release the water when directed by the Raspberry Pi.
The Raspberry Pi is responsible for running the web interface, accepting user input for new messages and sending the command to trigger the water-based printing system.
This is an awesome and unique project for sending fun messages to friends and family for special events.
And maybe Ryder could do a more permanent print using paint instead of water on a road or long driveway as an art project.
It is a little harder to get permission to do that though!
Nonetheless, this project, a Raspberry Pi truck dot matrix water printer, is a first if it’s kind, and Ryder could make money from it :-)
