Rust 1.46 has added the ability for error functions to put the caller in the stacktrace instead!

A family member asked me about laptops, and I was surprised to see a modern laptop with a 1.0 GHz clock speed!
The Intel Core i5-1035G1 https://ark.intel.com/content/www/us/en/ark/products/196603/intel-core-i5-1035g1-processor-6m-cache-up-to-3-60-ghz.html can dynamically scale up to 3.6 GHz. Seems like manufacturers are no longer scared of small clock speeds in marketing.
LambdaMOO has prototypical inheritance, so you create objects from other objects.
@create $note named "Old Post-It"
You now have Old Post-It with object number #51116 and parent generic note (#9).
An object that can have children is called 'fertile'!
Finding a MUD client today is a battle against bitrot. I've been using tintin++, one of the few clients that is still maintained.

Fedora Silverblue is an interesting immutable Linux distro. It's like a LiveCD (e.g. Knoppix) but you can create new versions (like LVM snapshots).

This comparison of OpenSmalltalkVM and TruffleSqueak is a really effective demonstration of JITs.
TruffleSqueak initially has a lower framerate, but eventually exceeds OpenSmalltalkVM. As soon as the GUI is used (at 3:30), the framerate drops again!
I really value builds, lints and coverage metrics on pull requests. This still feels like an underexplored area though.
There's no Travis equivalent AFAIK for performance. I'd love to have automatic benchmarking on contributions.
I find test coverage a useful thing to track, but I can't find a good metric.
"Coverage decreased by 10%" sounds bad. If you're deleting pointless code that has tests, it's good!
Perhaps total untested lines of code is better?
Docker Hub will start deleting images that haven't been pushed or pulled in 6 months: https://www.docker.com/pricing/retentionfaq
I self-host most of my servers, but it's nice having all my images available on an external service.

Not simply wrapping libgit2!
@meta Thanks, I'd not seen that before! https://en.wikipedia.org/wiki/Galapagos_%28video_game%29
Interesting it came out at the same time.
Xbox is moving to model where you can stream games, and the platform you're using (even PC!) matters less.

Today I learnt that Haskell has *three* ways of changing what syntax means!
Quasiquotation: https://wiki.haskell.org/Quasiquotation
Template Haskell (like Lisp macros): https://wiki.haskell.org/Template_Haskell
RebindableSyntax:

Bevy is a game engine written in Rust with a superb project introduction: https://bevyengine.org/news/introducing-bevy/
Videos! Clear rationale! A ton of examples with screenshots of the results!
Today I needed a library that takes a regular expression and gives you a string that matches. https://github.com/fent/randexp.js fits that need nicely.
Unfortunately, reading the docs has introduced me to evil patterns like /a^/ and /\1 (a)/. Yikes.
Emacs 27, with harfbuzz for fonts, arbitrary sized ints, native JSON parsing, and portable dumping replacing unexec! https://lists.gnu.org/archive/html/emacs-devel/2020-08/msg00237.html
Clojure is changing how entry points are handled, with a default convention for command line arguments: https://insideclojure.org/2020/07/28/clj-exec/
Re-examining what the main function looks like is a really good exercise!
