I highly recommend writing an interpreter if you get the opportunity. It's a lot of fun and deeply educational.

It's always dangerous to say "I've used this X years / written Y lines of code and never needed Z". No-one has experienced every use case.

"One of your test API keys has been filled into the examples, so you can test out any example right away." Stripe, I'm impressed.

Was nerd sniped today. Write a function in Python that flattens a list of arbitrary depth. My solution: http://t.co/TBwNrkqZjE

Today I learnt about iptables-apply. It undoes firewall rule changes if you've accidentally locked yourself out. Replaces my custom scripts!

Non-ASCII characters in domain names -- very hard to display them correctly in all browsers: http://t.co/TqbNHJSWtd

"Some developers learn APIs through “apprenticeships” with expert Stack Overflow users." -- http://t.co/Hw562Tqjlo

That moment of suspicion when code works first time.

Saw a legitimate 3D printer for £120 today. The future has arrived!

Augeas: http://t.co/89ealBpXHF is very cool. It parses config files, so you can modify them without ad-hoc scripts that might break syntax.

Monitoring emails tend to be uninspiringly worded. I'd much prefer a Scotty (of Star Trek) impression. "She's down to 50MiB cap'n!"

Uniquify will be enabled by default in Emacs 24.4! Great news -- it's a brilliant Emacs feature that not enough people know about.

Curly braces in Python: http://t.co/4jjtupRgYq

Learnt about `set -u` in bash scripts today. Ensures all your variables are defined, very handy (think `"use strict";` for shell)

New version of IntelliJ is out! It might be time for a visit to non-Emacs-land to pillage features and ideas!
