Cool. Original author here. AMA.
Would huge pages help with the mmap case?
According to MDN Safari clamps it to 4 or 8, but Firefox does not: https://developer.mozilla.org/en-US/docs/Web/API/Navigator/h...
I always found it annoying that CPU information was widely available and precise while memory information was not - it's clamped to 0.25, 0.5, 1, 2, 4 or 8 GB. If you're running something memory-bound in the browser you have to be really conservative to avoid locking up the user's device (or ask them to manually specify how much memory to use). https://developer.mozilla.org/en-US/docs/Web/API/Device_Memo...
I was thinking of https://bugzilla.mozilla.org/show_bug.cgi?id=1984333. Looks like that's only active when certain fingerprinting protection settings are on.
TIL the CPU count is exposed to JS. I guess that's fine? It feels nasty, but it's not really worse than all the other fingerprinting data we expose...
I might be wrong but I think I heard that Firefox and maybe Safari bin that to a couple common values. (Or maybe that's just in the tracking-prevention mode that Tor uses?)
They first disabled rubocop to prevent further exploit, then rotated keys. If they awaited deploying the fix that would mean letting compromised keys remain valid for 9 more hours. According to their response all other tools were already sandboxed.
However their response doesn't remediate putting secrets into environment variables in the first place - that is apparently acceptable to them and sets off a red flag for me.
Duh. Thanks for pointing that out.

Interesting that all nouns are capitalized, like in modern German and unlike in most other modern languages that use the Latin alphabet.
Decreasingly so, but even in stuff written in the last hundred years or so you'll sometimes find words capitalized for emphasis or similar.

This is very exciting, congrats to the Firefox team!
My company is working to bring Unreal to the browser, and we've built out a custom WebGPU RHI for Unreal Engine 5.
Here are demos of the tech in action, for anyone interested:
(Will only work on Chromium-based browsers on desktop, and on some Android phones)
Cropout: https://play-dev.simplystream.com/?token=aa91857c-ab14-4c24-...
Car configurator: https://garage.cjponyparts.com/
On Firefox 142 (nightly):
Cropout: After being stuck at 0% for a long while and 1200 network requests, it loads to a menu with a black background and will start a game but only UI elements show up. Seems to have a lot of errors parsing shaders, as well as a few other miscellaneous errors.
Car configurator: Several errors while at 0% (never loads), the first among them being `[223402304]: MessageBox type 0 Caption Message Text Game files required to initialize the global shader and cooked content are most likely missing. Refer to Engine log for details.`
I would concur with others that you should at least test this in Firefox before advertising it here.

Last time I checked, Word was also basically untenable for math-heavy writing because there was too much procedure involved in setting a formula. This is fine if you need one here and there, but if you have lots of formulas (including many tiny ones, like just using the name of a variable), switching to a dedicated formula mode in the interface is just not pleasant. In LaTeX (or Typst), I just type $, and off I go.
Alt + = will put you in the equation editor fairly easily, and from there you can pretty much use LaTeX notation.
That's why if this was a serious attempt to gauge whether smartphones are diametral or beneficial, we'd have a double-blind, standardised anonymously-graded test. If control group with smartphones gets consistently less points by graders who do not know them or their smartphone habits as compared to those who live in digital exile, we can talk. Until then, 'peace and quiet' in the classroom is mistaken for educational success.
Funny how no-one seems to be eager to finance such a study. For me, that's an indication that the outrage is pearl-clutching.
> 'peace and quiet' in the classroom is mistaken for educational success.
To clarify, do you think that phones or the removal of phones leads to these outcomes? Do you think that teachers like or dislike phones? Or is the point that there are many biases both ways?
> they have rose-tinted ideas about the way things used to be
Some do. Are teachers the only ones?

I am not sure how you would set this up in a way that does not fall victim to a dozen confounding variables. There have been comparisons of standardized tests before and after phone bans, of course, but those also fall victim to similar statistical issues.
