(I am far from an authority on this so I could be wrong.) It seems there are two paths you can take: a plain ruby build to which you add what you need, then a ruby+stdlib build with "everything". I shrunk the latter as I wanted a "good enough" small build.

In terms of easy exclusions, you don't need rdoc, any libraries oriented around networking, minitest, etc. At least for making Ruby-powered frontend experiences (as opposed to developer tooling).

Got ruby.wasm down to 4,223 kB over the wire *including* the stdlib!
20MB+ is more typically seen in similar builds, but there's a ton of stuff that can't even be used in the browser including a huge needless C library. More to follow..

Sounds like I have a rabbit hole to go down! I've solely used it for ruby install and switching so far but I hear there's a lot more to it.

Been putting off moving off asdf to mise for managing Ruby versions for months. I shouldn't have. It took two minutes to migrate and it Just Works™.

UNIX commands are riddled with hundreds of command line options. Yet no quick way to list make targets, e.g. `make --list` or something 🤪

BTW you can play with it too, punch.sh – you don't get Opus on the free one, but GPT OSS is surprisingly good and even a million rounds will only cost me $10.
Punch
Give your copy more (or less?!) impact. AI-powered text editing for sharper writing.

Suffered a huge wave of botnet signups from an IP range that geolocates and has RIPE and ASN data pointing to the US, yet BGP routes to Moldova. Oh, I couldn't POSSIBLY speculate what nation state might actually be behind that 😏

Postgres folks! Today's Postgres Weekly is a particular banger: postgresweekly.com/issues/634
Someone's made an awesome forum-like interface for pgsql-hackers; a cute metadata hack; who built Postgres; a recently fixed Postgres bug from 1999; and, well a lot more.

I gave Kimi K2.5 a photo of me and asked it for the honest truth. It said I probably work in "a technical field where personality is viewed as a liability" 🤣

I bet this nonsense works really well with his base though. It's the "scare naive 60 year old working class conservatives" playbook dialled up to 11. The Daily Mail would be proud.

Oh I've gotta do a blog post about all these. Trump's email people are getting increasingly unhinged. They are now accusing "Pat" (whoever used my email address to join Trump's list) of being an illegal alien to get her to donate.
