GIMP 2.99 (RTheren)


  • The open source GIMP image editor, GIMP 2.99.18 has been released, and it is special because it is the last development release before GIMP 3.0, finally!
  • And there are some huge new features in this release that graphic artists have been waiting for, despite it being a work in progress.
  • The huge new feature in this GIMP development release that is so important for artists, is the initial support for non-destructive layer effects, which allows you to make changes to the original image without overwriting the original data, and allows you the option to revert back to it.
  • All the big proprietary graphics applications, like Photoshop, have the ability to work with images non-destructively, and is one of the reasons why they are industry standard.
  • Another big new feature, there is a new welcome dialog:
    • It has tabs for personalization, which allows you to adjust your theme, font scaling, and icons.
    • A contribute tab with links where people can contribute to the GIMP.
    • And a create tab, with handy buttons to create, open, and open recent images.
  • There are 3 variants of theming, dark, light and middle.
  • And a lot of improvements to color accuracy and improved color algorithms.
  • Make sure to check out the link to all the new features in our show notes.
  • And the link to download the GIMP 2.99.18 development version as a Flatpak.
  • This development release is a great way for the GIMP community to test bugs and report them.
  • They make it a point to let everyone know this is a VERY unstable version. 

Ardour 8.4


  • Ardour 8.4 is out and don’t worry, you didn’t miss a version. 
  • 8.3 was a bug fix. 
  • The interesting but for 8.4 is moving GTK2 into the Ardour source tree.  
  • They are doing this since it’s being deprecated in, well, everything. 
  • This will let them add, modify, or subtract bits needed for Ardour. 
  • Couple of updates for control surfaces and a few visual tweaks. 
  • AAF showing up in Ardour might come as a bit of surprise. 
  • Back in 2014 it didn’t really look like it would ever happen. 
  • AAF and OMF are both nightmares to work with and should be avoided at all cost.
  • If you get stuck, remember the name AATranslator. 
  • Or use Davinci Resolve to get what you need out of them since it can handle AAF, XML, and EDL.
  • Experimental AAF, or the Advanced Authoring Format, import is now available in Ardour 8.4.
  • I have used the AAF format heavily in Adobe After Effects, Adobe Premiere, Final Cut, Avid etc. for transfering audio and video settings from one program to another.

FireOne vs Liunx


  • Thirteen years before Presonus released the ioStation 24C, Tascam introduced the FireOne. 
  • A portable FireWire audio interface with shortcut keys, transport control, and jog wheel for use with your digital audio workstation.
  • You got a jog dial, transport controls, and a gang of function keys. 
  • On top of that, two mic preamps, MIDI, and Hi-Z jack for guitar. 
  • I took it for a spin on Debian 12 with pipewire, pulseaudio, and jack. 
  • It’s really a neat device that was ahead of its time. 
  • Has one big issue that might not bother some of you. 
  • Missing one killer feature. linu
  • Wow, that looks like the old video editing jog wheel I used to use back in the 90’s.

Slice of Pi

Quiet Pi 


    • Have you ever had that pesky neighbor blast music at full volume early in the morning?
    • Well here is how one person ingeniously did something about it with a Raspberry Pi 3!
    • And because this neighbor was using a bluetooth speaker to blast Reggaeton music, the developer built an AI device to disrupt it, and they state:
  • “Reggaeton Be Gone (the name is a homage to Tv-B-Gone device) will monitor room audio, it will identify Reggaeton genre with Machine Learning and trigger comm requests and packets to the Bluetooth speaker with the high goal of disabling it or at least disturbing the sound so much that the neighbor won’t have other option that turn it off.”
  • Parts:  Raspberry Pi 3, Push Button, microSD card, DFRobot Oled 128×32, 5v 3A power supply, 3d printed case, USB Mic or Board and Mic etc.
  • Software:  Raspberry Pi OS, Python, GTZAN music genre AI classification datasets trained to the developers own model of reggaeton.
