Podcasting & Streaming Setup (2020)

  • This is what you can stick together with a handful of Linux and a little patience on eBay. 
  • I’m not going to tell you it’s simple to set up, because it’s not but the next story might help with that. 


Pipewire updates 

  • Being able to wire pulseaudio sources directly to Jack sinks is exactly the kind of unicorn people like me have been waiting for.
    • This is not going to configure and set up Jack for you. 
    • Oh, well! So much for that then.
  • You can start poking at it if you have Fedora 32 installed somewhere that’s not your main production box.
  • It’s nice to see great progress on PipeWire.
  • The developers are aiming for PipeWire to be stable and ready in Fedora 34, and for PipeWire testing, stabilizing and new features in Fedora 32 and 33.
  • Right now Pipewire can communicate with Ardour, so it has that going for it. 
  • Work is being done on human readable audio devices so things like pavucontrol will make everything look and feel just like PulseAudio.
  • Pipewire now allows you to create new audio sink devices with Jack and Gstreamer. 
  • Still no word on netjack. 
  • Eventually apps will be able to target PipeWire directly (like Chrome does) but until that day it’s focused on making all your sound system are belong to us. 


Cubuntu? (RTheren)

  • Not a single fork yet.
  • I think I can see why.
  • I tried to go back and use Trinity after KDE went to 5 and they monumentally screwed it up, again, and I honestly couldn’t do it.
  • I was expecting functionality that was just not there.
  • I’m sure there is a niche for this kind of thing, just look at all the NeXT based DE’s.
  • As a lover of the classic Common Desktop Environment, I was looking forward to the success of this Ubuntu spin.


HP’s new Ubuntus

  • And now we have another major brand supporting Linux on the desktop!
  • HP’s latest high end ZBook series of laptops and Z Desktop workstations are now certified to run Ubuntu 20.04 LTS.
  • The laptops start at $1,989.
  • The HP ZBook Fury 15 and ZBook Fury 17, come with an Intel 10th gen core series or Xeon processor and an Nvidia Quadro RTX or an AMD Radeon Pro GPU.
  • And are aimed at AI developers and data scientists. 
  • Much like Dell’s efforts, I foresee having to dig through several different store pages before you get presented with the option.
  • Yes, I know you can go to linux.dell.com but 99.99% of everyone else doesn’t.


There is no K in annotations (RTheren)

  • I’m still a bit iffy on the “fancy QML” settings pages for somethings.
  • I used to really like the advanced window rules layout and how it presented everything.
  • Now I have to use a gosh darned search box or scroll like heck to find the option.
  • That’s not good design!
  • Great, Konsole launches faster!  I have noticed how sluggish it can be.
  • And Konsole’s default main window size is bigger.


Inkscape 1.0.1

  • Inkscape 1.0.1 has been released, and comes with a lot of great bug fixes, and a few new features that didn’t make it to the 1.0 release.
  • Color-managed PDF export to Scribus, the open source desktop publishing app for Linux.
  • New preferences option to limit screen tearing while editing.
  • The Snap now uses the system’s font cache and thus finds all installed fonts.


USB ID Repository

  • This could be handy for tracking down unlisted devices.
  • It is a public repository of all known IDs used in USB devices.
  • They maintain a nightly snapshot of usb.ids. 
  • You can run sudo update-usbids to update the list on debian-based distros.
  • This is awesome!!
  • I once plugged in over 30 mice to one computer and noticed a lot of mice that weren’t identified by the vendor.
  • Now I can contribute to the USB ID Repository.


OBS Captions 

  • This is using the Google Cloud Speech Recognition API.
  • The caption delay is usually less than half a second.
    • So the usual if you’ve ever used captions in a YouTube livestream.
    • That’s really good.
  • Configure with -DBUILD_CAPTIONS=ON.
  • Works automatically with Twitch live and VODs.

Slice of Pi

Theoretical RISC-V Pi

  • This is what we have needed to bring RISC-V to the mainstream market and encourage software development!
  • A RISC-V Small Board Computer that competes with the RasPi in price point.


Captain’s Pi (RTheren)

  • And to celebrate Star Trek’s 54th Anniversary yesterday!
