If you’re an app developer reading this, can you tell me, off the top of your head, how your app behaves on a link with 40 kbps available bandwidth, 1,000 ms latency, occasional jitter of up to 2,000 ms, packet loss of 10%, and a complete 15-second connectivity dropout every few minutes?

Multiple GitHub accounts (Work vs Personal)

This setup uses some tricks to ensure that the right email/name/ssh-key is used for the right repos without having to think about it ever again.

  • First generate two SSH keys, ~/.ssh/id_ed25519 and ~/.ssh/id_ed25519_work
  • Add one key to your personal account and the other to your work account

.ssh/config
