Discord Emoji

Note: This is written for those using Python 3 and discord.py, so if you're using something else please reference the relevant documentation for your language or library if you choose to use this as a general reference.

On Discord, there are two different emoji types:

Unicode Emoji
Custom Emoji

Each needs to be handled differently, as while unicode emoji are just simple unicode characters, Discord custom emoji are special objects available only in Discord, belonging to a specific Discord guild and having their own snowflake ID.

Hi there! Thanks for offering to let me take a HackerRank test for ABC, I appreciate the vote of confidence.

Docker on BTRFS is very buggy and can result in a fully-unusable system, in that it will completely butcher the underlying BTRFS filesystem in such a way that it uses far more disk space than it needs and can get into a state where it cannot even delete any image, requiring one to take drastic actions up to and including reformatting the entire affected BTRFS root file system.

According to the official Docker documentation:

btrfs requires a dedicated block storage device such as a physical disk. This block device must be formatted for Btrfs and mounted into /var/lib/docker/.

In my experience, you will still run into issues even if you use a dedicated partition. No, it seems it requires a standalone

prerequisites

Compile the program in gcc with debug symbols enabled (-g)
Do NOT strip the binary
To generate assembly code using gcc use the -S option: gcc -S hello.c

How to update a borrowck test for MIR borrowck

When we fix a bug in MIR borrowck, we often want to update an existing test and show that it does the same thing for MIR and AST borrowck. This gist describes the steps to do it.

compile-fail tests

An example of a test that has been updated to test both MIR and AST borrowck is borrowck-match-already-borrowed.
