  • Six years in the making.
  • Unity 7.6 has been released for testing and is back in active development! 
  • Yes, that controversial desktop manager created by Canonical that had replaced GNOME 2 in Ubuntu 11 years ago is back! 
  • You either loved it or hated it.
  • I did like Unity in the last few versions when it became faster and more responsive. 
  • The HUD and dash search were very progressive and reinvented the way we use traditional menus 
  • And elements of Unity are in use today in many modern desktops, like GNOME. 
  • The Unity 7.6 dash and HUD have been redesigned and are more modern and slick looking.
  • And so has the dock’s menus and tooltips.
  • I have been playing with Ubuntu Unity 22.04 since it was released last week.
  • And I noticed how it is much more memory efficient, and the desktop feels much quicker.
  • The memory usage in Unity 6.7 is supposed to be even lower than in Ubuntu Unity 22.04, where RAM usage has been reduced substantially to about 700-800 MBs.
  • Out of curiosity I cloned the git to see if you could fire this critter up in debian. 
  • build-dep needed about 15 things unavailable on Debian 11. 
  • It would be interesting to see this working outside of the Ubuntusphere. 
  • More desktops = more more better. 
  • Did any other distro have Unity?

Firefox turns 100


  • Firefox turns 100!  
  • Yes, the first three-digit version of Mozilla’s Firefox web browser has been released!
  • Firefox now supports captions/subtitles display on YouTube, Prime Video, and Netflix on videos you watch in Picture-in-Picture. 
    • Just turn on the subtitles on the in-page video player, and they will appear in PiP.
    • Unfortunately YT speech recognition is rather alright these days. 
  • Firefox spell checking now checks spelling in multiple languages. 
  • HDR video is now supported in Firefox on Mac watching YouTube videos.  I am sure this feature will be here soon for us Linux users.
  • Scrollbars on Linux and Windows 11 won’t take space by default. On Linux, users can change this in Settings to turn on scrollbars.
  • Some websites might not work correctly in Firefox version 100 due to Firefox’s new three-digit number.
  • New users can now set Firefox as the default PDF handler.
  • Worked OOTB on Debian 11. 

10 bit KDEnlive 


  • Oh nice, I like that kdenlive 22.04 introduced new effect templates.
  • So users can create, configure and share custom effects with each other via the KDE Store and download them into the app directly.
  • Now, not only can you create more advanced ready made effects for less skilled users, but this is HUGE progress to making more industry standard features available in Kdenlive that are offered in the likes of Davinci, Adobe Premiere etc.
  • As I usually do, I downloaded and played with the Kdenlive AppImage.
  • The render dialog looks so much nicer, and there is easier access to all the advanced video and audio settings.
  • And actually it looks more like older versions of the Kdenlive render dialog, which I liked before they updated it in the last few versions.
  • And it includes a ‘save your current preset as a custom preset’ button in the render dialog, so you can use and load them as you need.
  • 10 bit colour does not currently work with effects.
  • Kdenlive now runs on Apple’s M1 architecture.
  • Automatically transcode variable frame-rate videos.
  • The render dialog underwent a UI rewrite and gained a new custom profile creation.
  • I dropped in a segment of LGC as is tradition. 
  • It imported the DNxHD 290 and prompted me to change the timeline, good. 
  • Dragging the clip into the timeline gives a wee blink notification in the bottom middle centre of the screen letting me know there are not enough audio tracks for all streams 5.
  • Even Olive does this out of the box.  
  • Add the audio tracks manually and disable normalise audio thumbnails. On by default? 
  • Drag the footage into the timeline and hello desktop. 
  • Take 2 was more successful but it took several minutes for the audio waveform to render. 
  • Scrubbing through footage was smooth enough. 
  • 5 tracks of audio were playing. 
  • Rendering the footage with HW accelerated H265 resulted in another crash. 
  • While the ender dialog has been improved in 22.04 it’s still the kdenlive render dialog. 
  • I prefer quick access to codec, frame rate, container, encoder, resolution. 
  • Codec and sample rate for audio. 
  • Preferably in a dropdown menu. 
  • Also, I have tasted the ability to drag select in the timeline and I’m not going back. 
  • I could use Kdenlive 22.04 in a pinch and while that might not sound like a glowing endorsement it’s meant as one. 

MP3 for Resolve 


  • Resolve 18 B2 comes with a gang of features and one of them I care about. 
  • You can now export video / audio from the delivery page with MP3 audio. 
  • This might sound boring but up until now it was WAV only. 
  • I can export the podcast from Resolve \:D/
  • Still no AAC import / exp  or support for VST plugins but I will take what I can get. 
  • Oh, awesome Venn!

Slice of Pi

Mega PIxel Pi 


  • NGL, those images look a little bit of alright.
  • It is available now for pre-order at 40% off at $ 35.99.




  • Fedora 37 will remove the X.org drivers for both fbdev and the generic VESA driver.
  • Eventually, X.org itself will be removed, as the various desktops that Fedora offers shift over to Wayland.
