@andywingo Re-reading your excellent perf post whilst Guile bootstraps. Curious re your thoughts on JIT overheads:

Nifty Emacs feature of the day: indirect buffers https://www.gnu.org/software/emacs/manual/html_node/emacs/Indirect-Buffers.html -- fantastic for narrowing in multiple parts of a file!

The context sensitivity of C’s grammar: https://eli.thegreenplace.net/2011/05/02/the-context-sensitivity-of-cs-grammar-revisited "the pure-and-nice YACC grammar samples you find online for it are wrong"

Significant whitespace in a lisp! https://pasterack.org/pastes/6205 (racket cunningly uses indentation to suggest the correct line to fix)

I am regularly impressed with Cider. Today I'm digging the friendly, unobtrusive UI for step debugging.

TIL that F1 will open a help buffer for the current completion candidate in company! Awesome! How did I miss this?

Git undo, a wonderful example of git gymnastics:

Moving from React to React+Redux rather feels like moving from imperative to functional. There's major learning curve, but it's rewarding.

Emacs command of the day: lispy-flow, part of lispy. It Does The Right Thing when moving forward through nested sexps.

RSS readers would massively benefit from a Netflix-style suggestion engine. I can find academic papers, but no products available!

Twitter cards are widely used metadata, but we don't have GUIs showing it nor indexing! https://medium.com/@anildash/the-lost-infrastructure-of-social-media-d2b95662ccd3#.i4d8x9y88 (plus other good insights)

The more I think about it, the more I like self-quoting symbols by default. Otherwise you get "value of foo is bar, but you must use 'bar".

I'm playing with Emacs trunk today. Works well! If anything, I think Emacs trunk is a little faster than 24.5.
