pygy_··on Allow me to introduce, the Citroen C15
Brits are usually pretty good at taking the piss…
pygy_··on JavaScript engines zoo – Compare every JavaScript engine
That argument was vaguely plausible until WebKit/JavaScriptCore shipped PTC and literally no one bat an eye.

Bun users don’t care either.

At this point it is pure BS.

pygy_··on Claude wrote a functional NES emulator using my engine's API
There are NES emulators aplenty, the only value in writing a new one is pedagogic, for the writer.

This endeavor had negative net value.

pygy_··on Mozilla appoints new CEO Anthony Enzor-Demeo
There is a difference between having an opinion and spending money to promote it.

Also, beside the direct murders as @ceejayoz mentioned, the social exclusion of LGBT folks drives far too many of them to many of them to suicide.

The legalization of same sex marriage cause a noticeable drop in their suicide rate (https://en.wikipedia.org/wiki/Suicide_among_LGBTQ_people#:~:...).

pygy_··on Covid-19 mRNA Vaccination and 4-Year All-Cause Mortality
Another factor that may play a role: the people who chose not to take the vaccine may be prone to taking bad decisions more broadly, leading to a higher mortality rate.
pygy_··on Covid-19 mRNA Vaccination and 4-Year All-Cause Mortality
There is plenty of evidence beside this study.
pygy_··on Covid-19 mRNA Vaccination and 4-Year All-Cause Mortality
The vaccinnated group was 1 year older on average, and had mode cardiovascular risk factors.

Covid has long term health consequences, and these are proportional to the severity of the acute infection.

People who died of a stroke of a heart infarction 6 months down the line were not counted as "covid death", even though covid is known to increase their incidence in the next year.

pygy_··on Universal Consciousness as Foundational Field
@dang this may be a good candidate for the second chance pool

The author has a strong quantum physics background, and makes testable predictions [1].

This isn't circular fluff as argued in this thread, but a mathematically fledged theoretical framework.

pygy_··on AI CEO – Replace your boss before they replace you

Called it, six years ago :-)

I can see boards of directors drooling at the potential savings.

pygy_··on We Induced Smells With Ultrasound
This is TFUS [1] with a novel target.

It looks like independent hackers with a strong technical background and little regard for decorum.

Their methodology seems reasonable, and their results are plausible.

I’m reserved about the final part of the post where they moot about applications, but the core result seems solid. They elicited osmosphenes like one can elicit phosphènes by targeting the visual cortex.

Great, thanks!

Oh... could you elaborate?

pygy_··on Study confirms that pianists can shape piano timbre through touch
This is probably negligible, but the hammer is not perfectly rigid. The tension in the stem at the time the hammer escapes and subsequent oscillations could also play a role.
pygy_··on I'm leaving Ruby Central
And the best way to build trust in the new tool is naturally to sabotage the old one.

rv builds on André's reputation. The best way to squander it would be to attack the rubygem infrastructure.

pygy_··on Hashed sorting is typically faster than hash tables
You could also use a random salt (for i64, add it up with wrap around overflow) with minimal overhead.
pygy_··on "Remove mentions of XSLT from the html spec"
The old, bug-ridden native XSLT code could also be shipped as WASM along with the browser rather than being deprecated. The sandbox would nullify the exploits, and avoid breaking old sites.

They actually thought about it, and decided not to do it :-/

pygy_··on ADHD drug treatment and risk of negative events and outcomes
Patches are changed once per day, and their pharmacokinetics isn't addictive (the nicotine blood levels rise too slowly to give you a dopamine boost).

I sometimes realize in the afternoon that I forgot to change my patch in the morning because I'm a bit drowsy (a feeling not unlike being uncaffeinated when you're used to drinking coffee). AFAIK the withdrawal symptoms fade out in at most a week.

pygy_··on ADHD drug treatment and risk of negative events and outcomes
I don't know if the evidence is more than anecdotal, but I've read that ADHD smokers who are taking adderal have to increase the dose of their treatment to remain functional when they quit smoking.

I've been taking nicotine patches for half a year now, with great success (and it is available OTC unlike other stimulants). Nicotine in itself isn't toxic at these doses (7, 14, 21mg), it's a cool life hack :-).

pygy_··on I tried vibe coding in BASIC and it didn't go well
I tried vibe coding WebGPU/WGSl, which is thoroughly documented, but has little actual code around, and LLMs are pretty bad at it right now.

They don't need a formal model, they need examples from which they can pilfer.

pygy_··on I tried vibe coding in BASIC and it didn't go well
I've had a similar problem with WebGPU and WGSL. LLMs create buffers with the wrong flags (and other API usage errors), doesn't clean up resources, mix up GLSL and WGSL, write semi-less WGSL (in template strings) if you ask them to write semi-less [0] JS...

It's a big mess.

pygy_··on Molecule produced by gut bacteria causes atherosclerosis
My bad, I read the paper too fast.
pygy_··on Molecule produced by gut bacteria causes atherosclerosis
TMAO is the precursor of imidazole propionate.
pygy_··on Shipping WebGPU on Windows in Firefox 141
It works in Chromium on MacOS, but I'm not a fan of the FF VI music rip off (Terra's theme: https://youtu.be/GxLbTAA6gK0?t=11).
pygy_··on Do Insects Feel Pain?
The other "spiders" may be its molts. In any case, if it's growing, it's eating other bugs...
pygy_··on JavaScript Benchmarking Is a Mess
I hadn't run these in a while, but in the current Chrome version, you can clearly see the multi-modality of the results with the dummy Math.random() benchmark.
pygy_··on JavaScript Benchmarking Is a Mess
I have been sleeping on this for quite a while (long covid is a bitch), but I have built a benchmarking lib that sidesteps quite a few of these problems, by

- running the benchmark in thin slices, interspersed and suffled, rather than in one big batch per item (which also avoids having one scenario penalized by transient noise)

- displaying a graphs that show possible multi-modal distributions when the JIT gets in the way

- varying the lengths of the thin slices between run to work around the poor timer resolution in browsers

- assigning the results of the benchmark to a global (or a variable in the parent scope as it is in the WEB demo below) avoid dead code elimination

This isn't a panacea, but it is better than the existing solutions AFA I'm aware.

There are still issues because, sometimes, even if the task order is shuffled for each slice, the literal source order can influence how/if a bit of code is compiled, resulting in unreliable results. The "thin slice" approach can also dilute the GC runtime between scenarios if the amount of garbage isn't identical between scenarios.

I think it is, however, a step in the right direction.

- WIP WEB UI: https://flems.io/https://gist.github.com/pygy/3de7a5193989e0...

In both case, if you've used JSPerf you should feel right at home in the WEB UI. The CLI UI is meant to replicate the WEB UI as close as possible (see the example file).

pygy_··on What’s the difference between an -ectomy, an -ostomy, and an -otomy? (1986)
Anatomy derives from Latin. Physiology, pathophysiology and operational terms derive from Greek.
pygy_··on New seafloor map only 25% done, with 6 years to go
Extracting these resources means destroying the ecosystems that live on top of them.

So, yes, they are better left to their own devices.

pygy_··on How Venus ended up with a mini-moon named Zoozve
The orbit varies with time in a cyclic fashion and if you trace it for its whole cycle you get the horseshoe.
pygy_··on The Ladybird browser project
It is my understanding that Apple losing here would prevent them from enforcing WebKit as the sole iOS browser engine. I may be mistaken.
