Fix Intel Bluetooth

Intel Bluetooth sometimes seems to stuck in a weird state where it cannot response to any command (e.g. Bug #1790454). Bluetooth will simply not working when this happens, and can only be fixed by unplugging the computer from any power source (reliable) or restart until it works (may took 5-10 tries for it to work).

This script simply try to unload the driver and reload it with an option to repeatly doing so (press R) until it started working. It is written for runit, so when used elsewhere you might want to replace sv stop and sv start lines to systemctl stop bluetooth.service and systemctl start bluetooth.service respectively.

Gopls and the Rabbit Hole

gopls v0.9.5 hangs when visiting a buffer when running under eglot under Mac GUI for some reason. Downgrading gopls to v0.9.4 make it works under eglot again. Naturally, I would assume this was a regression with gopls. git bisect indicates that the first "bad" commit was https://github.com/golang/tools/commit/cd31eaad03d53a18fa4b5e25b94d0b65e7380349, which means it should fail since v0.8.2, but for some reason installing via go install golang.org/x/tools/gopls@vX.Y.Z worked up to v0.9.4, even with go 1.19, and even v0.9.5 works fine when running under LSP client (Sublime Text).

In an attempt to find out if this code path was indeed an issue, I cloned the latest commit and attempt to stub out gopls/internal/vulncheck. Fortunately, this particular code were already stubbed out for go version older than 1.18, so removing this code was easy:

diff --git a/gopls/internal/vulncheck/command

Fix iTunes Library

This is a one-off script to fix broken Location entry in iTunes Library.xml.

iTunes internal database will sometimes have a broken file location when exporting. For example, for a purchased song, it might still have a reference to a temporary file at iTunes Media/Downloads rather than file inside iTunes Media/Music directory. While iTunes itself doesn't seems to use these locations for its playback, it becomes problematic when other music players try to import the iTunes library data (e.g. Swinsian).

This script will parse iTunes Library.xml to detect broken file location and try to find the file. This script was created for personal use, so it may or may not work in your environment. Use it at your own risk and remember to backup the library before trying!

You should not need to use this if you're not syncing the iTunes library with other media players on a Mac.
