Racket docs are superb. The explanation of lenses is really accessible: https://docs.racket-lang.org/lens/lens-intro.html (some great examples and rationale)

Whilst the ownership system is the headline feature, I find Rust's immutable-by-default vars and private-by-default fns to be a huge change.
Sly (a fork of Slime) has a really neat notion of 'stickers'. It's essentially a break point plus watch expression:
The alphabet soup codecs shown are expensive proprietary standards. It's great to see open collaboration win. 2/2
The Opus codec was developed for low latency speech encoding, but it's incredibly good at all bit rates! 1/2
Great introductory talk on Pony: https://www.infoq.com/presentations/pony (actor-based language with E-style capabilities!)
Pharo's exception system is my new fave. You can resume, retry—like other condition systems—but with great syntax!
A neat result of Pharo reifying the stack: CI can just dump the stack, and you can continue locally! https://github.com/hpi-swa/smalltalkCI/issues/146#issuecomment-222537286 (cf core dumps)
Smalltalk reifies the stack as objects you can manipulate. Interestingly this allows even serialising continuations! https://news.ycombinator.com/item?id=10099817
Just realised that #pharomooc is using #moocpharo as the official hash tag. Argh. I thought it was quiet.
TIL about midnight-mode, an Emacs package for cleaning up old buffers: https://emacs-fu.blogspot.co.uk/2010/03/cleaning-up-buffers-automatically.html (courtesy of #churchofemacs today!)
At least, this has been my experience with Scheme. I think Shen and Forth run the same risk. 2/2
A lang should not be too easy to implement, or devs have more fun writing an interpreter than learning how to use the lang effectively! 1/2
Emacs 25 will introduce xref, a generic go-to-definition framework! https://www.reddit.com/r/emacs/comments/4m9rle/how_is_the_emacs_25_pretest_faring/d3u6myu (obsoletes the find-tag commands)
