A weekly dose of all thing Linux and open source with a slice of Pi for good measure.



Colour key – Venn Jill Pedro


  • If this works, great!
  • But I have seen plenty of times when a PC goes to sleep, upon wake up things won’t be working.
  • This, in my uneducated opinion, feels like it would make the issue worse.
  • But hey, maybe that’s just me.
  • This is a great solution to the cat moves mouse problem, but what if your cat hits the enter key on the keyboard, which then reinitialise the mouse.  Of this I am certain where a cat is concerned ;-D
  • I know one of our patreons and LinuxChix LA, smichelle, could benefit from this on her home and work computers, as someone who saves cats and does TNR.  She has had many accidents of this nature with her laptops.


The good RGB

  • Certainly opens XFCE to people who go completely anal over color accuracy.
  • Also, being able to set the profiles on a per screen basis is very welcome!
  • My favourite colour is dark.
  • This is wonderful for artists who need color management and profiles as accurate as possible and that work globally among all devices.
  • Gnome and KDE have already integrated colord support via GUI in their settings dialogs and settings daemons.


Secure Fedoras

  • Google Authenticator is awesome, when compared to some of the 2FA options out there.
  • I’m sure there are some who don’t want to give Google even more power, but this is actually a really good idea if you want to keep your ssh connections a bit safer.
  • Do be mindful of your organization policies.
  • This so makes sense, especially since SSH is one of the most used applications on Linux, and is used to connect securely to a remote system.



  • MAC’s will be custom ARM by this time next year, Linus.
  • ARM processors will provide much lower power, better heat dissipation and a lower cost server solution.
  • Lower power RISC-V server adoption may soon be in our future as well, especially now that RISC processing is back in vogue again.
  • Remember the days of the DEC Alpha?
  • Currently there aren’t as many linux applications compiled for ARM in our repros, but that could change over time.
  • Fact of the matter is, x86 is established, most developers are running x86 machines as their development machines, and are targeting x86 servers.
  • The argument of cross building and testing is weak. I’m not sure what Linus was going for here, maybe something a bit more bitey that he decided to hold back, but this is a weak argument.
  • Personally, I think ARM’s lower power package makes it ideal for server deployment/development.
  • At least for servers which require more reliability rather than performance.


No Snap

  • Yeah, I saw and liked Popey’s tweets on February 23rd.  That’s how I found out about this scary rumor!
  • Speaking of native development, do you want to learn why not having applications run natively?
  • Still, this was a community member posting this and that makes it anything but official.
  • Chill!


Chromed Ears

  • Progress!
  • I still want to play some vidjagames from my Steam library on ChromeOS.
  • Audio input is not supported yet due to security reasons of third party apps having access to the device’s microphone or camera, which could violate Google’s Chromebook security policies.


Boot hack

  • Not really for hacking but a way to install on otherwise locked devices?
  • This isn’t a complete tool.
  • This is just the UEFI hack to get around secure boot and still let you boot an .efi file.
  • You can literally build anything you want around this.
  • This is great for data recovery, reinstalling your OS or just being able to boot from a flash drive on a Secure Boot system.



  • I have been following the new members joining the Linux Foundation for many years, and have been so happy with the huge increase in membership the last several years!
  • Yes, new members have been averaging once a day for the last year.
  • HP Inc, HP’s desktop and laptop computer division, finally joined the ranks. Hmm, maybe HP is seeing a future of Linux on the desktop like Dell has?
  • HP Enterprise has been a platinum member since 2012.
    • Wouldn’t put it past HP to have a project sputnik of their own in the works.



  • VAAPI for Linux, means you can have QuickSync streaming on your Intel laptop.


    • And AMD.
  • It looks horrific if you are wondering.    
  • Multi-track audio support for FFmpeg
  • Two weeks ago we talked about the OBS Studio 23.0 Release Candidate 1, but now the final version of OBS Studio 23.0 has been released.
  • There are new ways to support OBS development, Open Collective and Patreon!

Slice of Pi



  • The Raspberry Pi Foundation updates its devices to the Linux 4.19 kernel.
  • Linux 4.19 is a Long-Term Support (LTS) kernel, and as we talked about during its release last October, it improves the performance of the Raspberry Pi, ARM and Broadcom devices.
