CPU clock speed, FLOPS, number of cores, die shrinking: progress in all these areas is now much slower.
What areas of tech are still exponential?

Some clever performance techniques for Emacs startup are discussed in the doom-emacs readme:
"We’ve told stories about inanimate things coming to life for thousands of years, and these narratives influence how we interpret what is going on now"

I've been playing with mercurial lately and the defaults are really interesting.
There's no staging area, so by default 'hg commit' is like 'git commit -a'. Seems beginner friendly.
Also, branches are optional! It's much easier to start working on a feature.
Atlassian created Stride in 2017, already had Hipchat, and it's now deprecating both in favour of Slack: https://www.atlassian.com/blog/announcements/new-atlassian-slack-partnership
Consolidation is happening very quickly! It reduces the number of self-hosted options though.
What proportion of Americans don't use the Internet, and what are their demographics?
@kensanata@octodon.social @ckeen @JordiGH@mathstodon.xyz For sharing whole packages or writing official docs, I suppose GitHub and a README.md are more common these days.
I do refer to the wiki several times a week for all the additional reference material and advice though :)

This elisp is building a closure!
Today I learnt what specpdl means in Emacs internals!
Special variable PushDown List.
Special variable means a dynamically bound variable, and pushdown list means a stack.
Interesting discussion of inefficiencies in elisp bytecode during function calls: https://www.xemacs.org/Architecting-XEmacs/faster-elisp.html
(From the XEmacs site, but entirely applicable to GNU Emacs and Remacs too I think)
Have you ever wondered which buffers have a buffer-local variable set? It's now possible to view every buffer with an overridden value using helpful.el!
.@magit_emacs has some brilliant error messages. This one made me smile.
