This can be useful to test the effect of a change to build scripts,

Tired of spamming Yubikey one-time password (OTP) codes into Slack? Here are two options to help prevent that. You can do either or both. Both require ykman, the Yubikey CLI configuration manager. Get it with Homebrew:

brew install ykman

If you…

• …don't have Homebrew? Install it, then run the command above
• …don't feel comfortable running terminal commands? Skip to the bottom
• …aren't sure what the big deal is? See "What's the big deal with Yubikey codes?" below

How to use matrix.org and vector.im as an IRC client

How to Join an IRC Channel on matrix.org

Join the room #freenode_<#channel>:matrix.org, replacing <#channel> with the name of the IRC channel. For example, in order to join the #prometheus IRC channel, join the room #freenode_#prometheus:matrix.org on matrix.org.

In vector.im, rooms can be joined with the directory symbol on the bottom left.
