Big Sur GPU Bug

Howdy! You‘re here because, ever since you upgraded your 2018 MacBook Pro to Big Sur, you’ve been experiencing consistent beachballing and hard freezing issues. You probably figured this out after finding lots of messages like this in the Console during a lock-up:

UPDATE: THIS WAS WRITTEN BEFORE BlueHeron EXISTED

This is a braindump of my progress over the weekend to look into Bluetooth support on Nerves. While Bluetooth has a lot of specs, supporting a subset of BLE that makes it easy for Nerves devices to communicate with cell phones and back would be generally useful.

There are two options for BLE support on Nerves:

1. Make a custom Nerves system that uses bluez
2. Use Harald

diskutil erasevolume HFS+ 'RAM Disk' `hdiutil attach -nobrowse -nomount ram://XXXXX`

where XXXXX is the size of the RAM disk in terms of memory blocks.

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
