you have probably heard that webassembly supports garbage collection. are you looking for an ahead-of-time compiler for wasm with gc? as it happens, i have written a little monograph on the topic https://wingolog.org/archives/2026/02/06/ahead-of-time-wasm-gc-in-wastrel

to everyone in europe who is revolted by the migrant kidnappings in the usa : we have our work cut out here, too. this year has been particularly hard in france because of the new restrictions on “régularisations” imposed by the interior minister, by decree, without a vote. we must stop the advance of the right before it gets even worse.

i have had a few air quality meters and appreciated them, changed some things about behavior and house as a result; but the annoying thing about many is the need for mains power. even if they have a battery it usually runs out and you forget to re-plug. like these two (co2 meter and pm10 meter)

with regards to RMS. he is a creep. did some good things in the past. built the fsf around himself, not around free software; there was overlap in the past but not any more, for a decade at least, as the fsf is just an ineffective advocacy org that does no work. i no longer think about rms or his org and you should not either. shun and let wither.

js the language used to be ok, and now it is good and even great sometimes. this happened because people decided to work together, and because it was all funded by ads and phone sales and what-not. both conditions have been necessary, and both are lacking if we push responsibility out to "tooling"

2024-10-08 09:12:49 UTC

a tiny js0 take: a working economics of collaboration and progress is fragile. unhooking js development from browsers will break the machine, and i don't know that it can be put back together again

it seems there are other c++ programs embedded as webassembly on ui.perfetto.dev

2024-09-20 12:24:32 UTC

a funny webassembly story: perfetto.dev's native trace format uses protobufs. it used to be json, which was used by chrome://tracing. there is a CLI program to convert between binary and json, if you need it; and to open a binary perfetto trace with chrome://tracing, perfetto will run that converter in webassembly https://perfetto.dev/docs/quickstart/traceconv#opening-in-the-legacy-systrace-ui

sure. i just think that such propaganda *as a tactic* is often motivated by an incorrect theory of social change. i would be happy if time proves me wrong of course :)

you can externalize some of the cost by reusing components made by apple / google / mozilla. all of the alternative "browsers" do this except ladybird afaiu. servo re-uses quite a number of things from firefox and that's fine and great. shitting on mozilla while arguing for servo or on google while using some chromium variant is nonsensical

2024-09-19 08:48:41 UTC

lukewarm take: funding a browser via voluntary individual donations will not work. browers are too expensive. (could they be cheaper? maybe, but there is a lot of essential complexity.)
browsers need a bigger funding structure. the only appropriate strategies that i know of are ads (all of them), product sales (apple could do this) and taxation. i would prefer the latter (i.e. the eu funds a browser), but barring that i do not fault companies using other strategies

it should bring it in! if you are zeroing just before allocating, but in a big enough chunk to vectorize, then you are in the happy space (afaiu, ymmv, &c &c)
in whippet this means when you find a hole, you clear it before allocating into it. but dynamics depend on the program, holes could be just 16 bytes or could be up to 64kB

well, embedding can let you turn this off. but i am not so sure it would be a significant perf win (caches being what they are), and it is a big help when debugging

being annoying can be good praxis. if you identify an injustice that most people don't yet see, the moral imperative is to be annoying enough to get others to see it too.
