There are so many topics where you can do online tutoring on Skype anywhere!
E.g. chess: https://lichess.org/coach foreign languages: https://www.verbling.com/find-teachers or programming: https://www.codementor.io/python-experts
It's amazing to have a teacher on the other side of the world.

On the design of programming languages, a great introduction to the constraints in choosing keywords, and a proposal for new keywords in Java: https://mail.openjdk.java.net/pipermail/amber-spec-experts/2019-January/000945.html
Do you ever find yourself doing something manually, even if the computer could do it with a bit of programming?
Even Ken Thompson has done this at times!

Over the last 15 years, ~50% of improvement in chess engines is due to smarter programming, not better hardware: https://www.reddit.com/r/chess/comments/76cwz4/15_years_of_chess_engine_development/
What other domains are like this? Lossy audio/image compression is definitely better today. There must be others situations.
One fascinating property of chess engine design is that a deeper tree search can be more valuable than a smarter board value metric.
If a metric is more accurate but more computationally expensive, it might not be worthwhile! It's a precision/brute force tradeoff.
Rust's model of references confused me when I started out. I'd read that they were faster, so I tried to use them everywhere. You can't return a reference to a new vector though!
Now I see them as primarily useful for signalling 'this parameter is not modified' rather than perf.
@cstanhope A friend also pointed out hotels dot com :). I do think they're rare though.
Reflecting on the dot com hype, there are actually very few sectors where genericnoun dot com has become one of the biggest websites. Seeing https://chess.com/ today made me think how rare it is.
Are the other big examples?
In addition to appliance manufacturers exploring smart/wifi-enabled devices, there are now products that allow you to trigger physical switches wirelessly! https://microbot.is/push/
Reviews are very mixed, but with hindsight this class of device was inevitable.
Activity trackers now exist for animals too! Whistle is a Fitbit-style exercise monitor plus GPS tracker for dogs: https://www.wired.com/review/review-whistle-3-pet-tracker/
Ambient computing is becoming progressively more common.
The Turing Test focuses on distinguishing between humans and computers in a text chat.
There are lots of other domains where it's interesting to compare styles. Do we make different mistakes in speech recognition? How easy is it to spot a chess AI masquerading as human?
Rust's for loop is much less ceremony than a traditional C loop, or even a Python for loop: https://doc.rust-lang.org/1.1.0/book/for-loops.html
Simple abstractions having simple syntax really helps teaching.

The efficiency of wasm is really impressive. An optimised build of Stockfish with POPCNT evaluates positions at ~1500kn/s on a single core of machine. By contrast, the wasm build on https://lichess.org/analysis/r4rk1/p5b1/2p2n2/1p2p3/4P2q/P1N1B3/1PP1B1Q1/2KR3n_w#0 can compute ~42kn/s in the browser for the same position!
GitHub will allow you star repo topics, not just individual repos: https://blog.github.com/2019-01-08-topic-starring/
Topics can be useful as a kind of hashtag to say what your project is about. I've not found them very useful for discovery so far. This could change usage patterns and improve matters!
