XFS Recovery

  • Yeah, guess who deleted something important and didn’t have a backup. 
  • Me!
  • It was on one of my XFS drives so things were extra tricky. 
  • Tricky because you will never guess what TestDisk does not support. 
  • Poor Venn!  LOL
  • This is why we tell everyone to make 3 backups of everything when possible, but we all forget doing this now and again.


Edubuntu is back 

  • Remember Edubuntu? 
  • It was an official flavour back in the day and I had forgotten about it. 
  • Edubuntu was for classrooms, schools, homes, and communities of education, but they pulled the plug in 2016. 
  • We have an important Ubuntu Linux Flavour that was lost in 2016, that will be able to resurface once again in our classrooms, Edubuntu is back!
  • The Edubuntu project had started back in 2005, and sadly, due to a lack of contributors, was ended with the release of Edubuntu 14.04 LTS.
  • Ubuntu Studio’s Erich Eickmeyer and his wife Amy, whose background is in education, are the ones stepping up to reboot and revive this spin.
  • The aim is to take part in the Ubuntu 23.04 release this April and, if all goes well, re-apply to become an official Ubuntu flavour.
  • Tentatively planned for Edubuntu 23.04: 
    • Will use the same desktop and apps as regular Ubuntu
    • New logo
    • Will use Yaru’s red theme by default
    • Default application folders by education subject (Math, Science, Language, etc.)
    • An installer based on Ubuntu Studio’s
    • Curated software metapackges based on age (ubuntu-edu-preschool, etc.)
    • A meta uninstaller to quickly remove ‘groups of irrelevant applications’
  • I was so happy to hear this!
  • When Edubuntu stopped development in 2016, a lot of teachers, organisations and schools had to find alternative distros to use, like UberMix.
  • Qimo 4 Kids, which was one of my favourites, also ended development in 2016. 


Handbrake AV1

  • AV1 is now officially in the Brake. 
  • The only hardware acceleration is for Intel cards at the moment. 
  • Still waiting on support for AMD and NVIDIA encoders. 
  • HandBrake is an application that I use constantly to convert files, and one I recommend my students to use.
  • They Improved the Linux GUI in parity with the Mac and Windows graphical user interfaces.
  • Thank you for the AV1 support, the NVENC HEVC 10-bit encoder support, and the H.265 4:2:2 profile for VideoToolbox encoder on Apple Silicon support!


Xfinity on Linux 

  • In the states we have a service called Xfinity Stream. 
  • It allows you to watch your cable service online. 
  • Handy If you want to watch on demand. 
  • It also has a completely arbitrary Linux block \:D/ 
  • Changing the user agent didn’t work. 
  • The plan was to extract Chrome OS’s Widevine CDM from a recovery image, load it into Firefox, and try to use Xfinity Stream.
  • Didn’t work because Google patched glibc with some extra bits. 
  • He ended up compiling glibc without GLIBC_ABI_DT_RELR. 
  • Back when I was on Cable, I remember doing a lot of hacks to get the TimeWarner app working on Linux.

Slice of Pi

Security Pi 

  • I’ve never considered building a DYI security system but this guy did. 
  • And to keep things interesting he used a RasPi3 at the heart of the system. 
  • After all, he wanted a system he soucl SSH into. 
  • A DIY security alarm system — powered by a Raspberry Pi that supports hardwired and MQTT sensors.
  • Supports both hardwired and MQTT sensors and outputs
  • Support for multiple MQTT alarm panels, with set states †
  • Home Assistant integration with auto discovery
  • The existing security systems have incredibly high monthly fees and are proprietary.
  • Anything that uses the open source Home Assistant is a great option.
