The git project contains quick checks (scans) on ways to improve system stability when it comes to low latency and real-time applications. This can improve jack to where the buffer size can be as low as 128x2 for USB class 2 audio hardware using a pre-compiled low-latency kernel. Should be lower (64x2?) for a custom compiled real-time kernel.. Otherwise using standard kernel you might still have issues at 1024x2 with a busy system.

Pulseaudio notes:

Shows how to create multiple sinks and sources (with the jack/pulse module) so you can point things like Discord or Skype or whatnot at jack uniquely

Been fairly happy with the new features in 15 Beta 1... Beta 2 is apparently out:

## x.sh
xrandr --output DP-0 --scale-from 1920x1080 #--scale 0.5x0.5

## y.sh
xrandr --output DP-0 --scale-from 2560x1440

## z.sh
xrandr --output DP-0 --scale 1x1

Looks like the logic inside modern Intel CPUs are too aggressive in pre-loading cache data and forget to check security boundaries... loading data from kernel (or possible other code space) into a region that malicious code could have access too:

Good starting links for learning about dithering:

Remapping channels to/from other devices (examples): (remember pacmd)
# from XR18 to OSB (inputs)
load-module module-remap-source channels=2 [...]

The fork with features (branches) and one fix (already applied upstream to original project).

Two features:
* local icons (the TTF is open source, and not everybody will have internet access)
* two panels for Transitions and Panels

The upstream project maintainer will probably accept the feature pulls soon.

Feeling kind of proud, knew nothing about Vuejs on Friday, watched videos Saturday, hacked code Saturday night and then Sunday afternoon...

and

Tada: github.com/dx9s/obs-tablet-remote My master with branches containing two features and possibly one fix.
