I really like how cargo gives you a Rust 'hello world' by default. Saves dozens of keystrokes!

TIL about -cut, a really neat macro in dash.el for partially applying functions using placeholders:
How popular is @magnars' dash.el? Well, even the last Emacs maintainer has contributed to it!
(In my current keyfreq history, I have isearch-exit at 530 calls, but highlight-symbol-next at 1017 calls!)
Emacs command of the day: highlight-symbol-next from https://github.com/nschum/highlight-symbol.el . I use it more than incremental search!
Archy was an amazing UI with persistence, modeless ZUI and an Emacs influence! https://en.wikipedia.org/wiki/Archy Why hadn't I seen this before?
Conventional OOP does type dispatch on the first argument, so foo.<TAB> in IDEs is helpful. Statically typed functions could do the same!
Zero-cost futures in Rust: https://aturon.github.io/blog/2016/08/11/futures/ (the scope for building efficient, elegant APIs across the whole ecosystem is exciting!)
eslint --fix, babel, lebab, uglifyjs and rollup: I'm extremely impressed with the versatility of the AST transformation ecosystem in JS!
Quite a few Emacsers live on the edge. From time to time, I stumble across code that only works on Emacs 25!
The #emacs channel on Freenode is an absolute goldmine of information. They're a great place to ask questions when you're stuck.
Want to highlight specific files you've changed in your commit? magit-commit-add-log (press `C') adds paths for you!
TIL in Emacs, pressing TAB in a *Help* buffer lets you jump straight to the links. Saves me ~5 keystrokes!
Historical defsubst macrology by jwz before the elisp byte compiler: https://web.mit.edu/~deberg/emacs/elisp/defsubst.el (cf #define in C!)
