First we start by creating a wineprefix and installing our prerequisites from terminal:

WINEARCH=win32 WINEPREFIX=/home/$USER/GarminExpress winetricks dotnet452 vcrun2010 corefonts

WINEARCH=win32 WINEPREFIX=/home/$USER/GarminExpress winetricks win7

# Program a SAMD21 part with a bootloader using a JLINK / J-LINK
# 0a. Wire up your device with SWD & SWC pins to JLINK
# 0b. Also wire up Gnd and Power to Gnd & VTref on JLINK
# 0c. And separately supply power to device 
# 0d. Iif you don't have openocd installed, then "brew install openocd"
#
# 1. Put this file in a directory
# 2. Get a samd21 bootloader file.bin and put it in this directory renamed as "bootloader.bin"
# 3. Unplug and replug in the JLINK (to reset it)
# 4. Then do "openocd -f ./openocd-sams21.cfg" and stand back

Problem

I have a notebook connected to a port replicator. I want to use the build-in speakers and microfone and not the external ones. If I boot my notebook in my port replicator Ubuntu changes the devices to external.

Solution

1. Find your internal speaker

using rust with rr

rr is a great debugging tool. it records a trace of a program's execution, as well as the results of any syscalls it executes, so that you can "rewind" while you debug, and get deterministic forward and reverse instrumented playback. it works with rust, but by default if you try it out, it could be pretty ugly when you inspect variables. if this bothers you, configure gdb to use a rust pretty-printer

rr is probably in your system's package manager.

Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages
