LWDW 250: Linus Wants An ARM

Linus wants ARMs

  • Lots of us Linux users and developers run Linux on Macs.
  • It would be nice if Apple made that official, like Dell and Lenovo.
  • Like most people Linus wants an ARM laptop. 
  • Guessing he would be a fan of the fanless design. 
  • Linux on the M1 should be possible? 
  • Unless Apple really doubles down on the lock in, in theory you should be able to.


Ubuntu Web Remix (LinuxGNUru)

  • It is so nice to see fast progress on this Chrome OS alternative that just started in the summer.
  • It’s hard for me to see this as a ChromeOS alternative when ChromeOS is so lightweight and works really well on passively cooled Celerons and ARM laptops
  • This runs what looks like GNOME.


Flash preservation 

  • I think we have just found the answer to playing our old flash games and animations!
  • Ruffle is an Adobe Flash Player emulator written in Rust, and works as a standalone app, for the web, and as a web browser plugin.
  • Ruffle works great, and you can try the demo.
  • It plays most flash swf games and animations, but if it doesn’t play the ones you want to play correctly consider contributing.
  • This is a neat project and it’s what the Internet Archive uses to Flash all the things. 
  • I tried the old Isaac swf from the Humble Bundle and that’s still a slideshow



  • Brilliant, a virtual white board for Zoom, Jitsi, Skype is so needed right now with so many of us at home working.
  • Difficulty: Requires a printer. 
  • Printing the symbols out once and then reusing them can be done.
  • Or if you’re skilled enough, you might be able to draw the symbols out yourself.


Ardour 6.4 er 5

  • Ardour 6.4 had a little issue with export so yeah, 6.5 is out and ready for consumption. 
  • You can build it from source as always or get it from your distribution. 
  • Binaries are available for backers. 
  • The big thing in this release is the addition of VST3 support. 
  • It will autohide VST2 plugins if it finds the equivalent VST3. 
  • That Is going to cause some confusion. 
  • Handling of MIDI encoders in “Generic MIDI” support is fixed.
  • Websocket/JS support now properly supports MIDI strips.
  • Several fixes for Ardour on RasPi. 


Pipe Wire for Fedora 34

  • Nuke Pulseaudio and Jack from orbit. 
  • All roads will lead to PipeWire. 
  • This will be really big for desktop users looking to take advantage of their audio interface. 
  • Holding off until netjack and FFADO support lands. 
  • Will we have to use GNOME to test this?
    • Nay.
  • For legacy ALSA clients, there will be an ALSA plugin that routes to PipeWire.
  • I still use some old music and demo apps that use ALSA and OSS, so this will be much needed!


Unstable Flatpaks (RTheren)

  • This will come in handy:
    • During a universal flatpak update, flatpak will now automatically add uninstall operations for end-of-life runtimes that are unused.
  • Getting the OSTree metadata and setting up the prerequisites for installing a flatpak on the local system will supposedly be faster now.
  • This should also allow people to only see/download a subset of flatpaks without having to have duplicate packages in the multiple repositories
    • The example they give are FOSS/non-FOSS package subsets


GCompris is 20

  • Yeah, GCompris is 20 years old and to celebrate, we now have version 1.0!
  • The GCompris is a suite of educational software for kids that has been used for years in schools, and in Linux distros that are used to teach children computing in third world countries.
  • This new version has a new Activity Settings menu with Dataset selection for more than 50 activities, allowing to choose more specifically what can be learned on the activities.
  • There is a new Analog Electricity activity which teaches how to draw circuits and run their simulations.
  • There are also new activities for addition, subtraction and typing as well.

Slice of Pi

ClockworkPi (RTheren)

  • This is the DevTerm from ClockworkPi, it is an open source portable terminal for every developer and Linux nerd.
  • DevTerm is an A5 sized notebook with a 6.8 inch ultrawide IPS screen and a ClockworkPI mainboard.
  • You can preorder the kit starting at $219.00 and it will ship by April 2021.
  • This reminds me of a mini version of the word processor I learned to type on, and one of my classic portable computers of yore.



  • No 8GB no interest. 
  • Rockchip RK3399; already have one of those.
