Per Wikipedia, at rest 500 ml of inhaled air is diluted with ≥2500 ml [1] of residual air in lungs containing ≥40000 ppm (4%) of CO2 [2]. Other things being equal, increasing concentration of CO2 in ambient air 10x (500ppm -> 5000 ppm) would increase concentration of CO2 in the lungs after taking the breath by less than 2.5% [3].

I imagine it could easily be compensated by an equivalently minor increase of breathing rate or breathing depth.

[2] https://en.wikipedia.org/wiki/Breathing#Composition

[3] 5/6 × 40000 ppm + 1/6 × 500 ppm = 33417 ppm; 5/6 × 40000 ppm + 1/6 × 5000 ppm = 34167 ppm; 34167 / 33417 = 1.0225

Can someone provide an explanation why CO2 concentrations above 1000 ppm have such a negative influence given the fact that CO2 concentration in lungs (at rest) never falls below 10000 ppm?

Then Otter Browser is a bastard faithful to the tradition

Weird, I remember Github as a pioneer of SPAs: in ~2013 you could browse code tree without the page reloading.

Though I agree today's Github is awful slow, JS is required to see issues, …

Damn, and my country consumes 11 million out of 13 million tonnes of coal used for heating houses in the entire EU.

It's even more to blame given that it stripped the NEA and IEEPA acts of legislative guardrails in 1987.

I've started questioning this premise given that concentration of CO2 in the lungs (while resting) never falls below 10000ppm (I'm possibly underestimating this number).

Though I'm not excluding the possibility that indoor CO2 concentration strongly correlates with cognitive underperformance, which may be caused by other compounds emitted by human body.

And whenever Congress delegates authority to the executive branch, it faces a basic principal-agent problem: how do you ensure that the authority will be used by the executive branch in ways that conform to congressional intent? […]

Beginning in the 1930s, Congress increasingly dealt with the delegation problem via another strategy: the legislative veto. Congress would provide authority to the president or other executive-branch officials, but reserve the right to overturn any individual use of the authority, via passage of a concurrent resolution in the House and Senate. […]

This essentially retained majoritarian congressional control over presidential uses of IEEPA. If Congress didn’t like an action the president took using his IEEPA authority — be it a sanction, asset freeze, or (gasp!) tariff — they would have the authority to overturn it, by majority vote, without the cooperation of the president.

But wait, you say, didn’t the House and Senate already both vote to overturn some of the the IEEPA tariffs put in place by Trump by declaring an end to the NEA emergency that triggered the authority? Yes, they did. […] But those were largely symbolic political votes, because the Supreme Court destroyed the legislative veto 40 years ago. […]

But even worse than that, the Court chose to sever the legislative vetoes from the laws in which they were placed. That is, the Court removed the legislative vetoes but left in place the delegations of authority! […]

Of course, Congress could just rewrite the laws with tighter restrictions on the delegated authority, or withdraw it all together. […] If Congress wants to change that […] they would need either the consent of the president (good luck), or a supermajority vote in Congress to override his veto.

I'll add that writing userscripts became more challenging b/c of this phenomenon.

True runaway (i.e. oceans boiling / Venus) cannot happen on Earth unless you significantly increase incoming radiation stream (or alternatively halve the planet's albedo).

The runaway effect is scary b/c at certain temperature (~400K) atmosphere consisting predominantly of water vapor looses its ability to radiate out more heat up until 1600K.

edit #2: I've measured some pixels and the starting runaway temp is closer to 315K / 42C, damn

Does anyone know if JWST has seen stuff far enough for this effect to kick in?

Sad reality of replacing plain old text boxes with "smarter" re-implementations: https://utcc.utoronto.ca/~cks/space/blog/web/WebEditingVsCut...

Some (including the most popular: codemirror) go as far as putting themselves inside "natural" selection flow: they're interpreting mouse inputs, cancelling default behavior and selecting text themselves (programmatically via setSelectionRange). And Firefox deliberately ignores such selection: https://searchfox.org/firefox-main/rev/edb7c6118aa4fc5b09d84...

Although I very like this feature, I find it insane there's no config option to disable it x-wide / compositor-wide.

Normal clipboard and selection "clipboard" (i.e. primary selection) are two separate boxes. Some apps (totally wrongfully IMO) override both when copying (example: Firefox's Web Developer Tools (e.g. copy element's innerHTML) but weirdly not the browser itself)

I should have put it clearer: every time the content of a textarea is modified by JS, the undo-redo history is cleared

Mozilla, please stop leveling down to others! Recently I discovered that Firefox goes to great lengths to discard <textarea> undo-redo history after it's been changed specifically via JS for web-platform (aka Chrome) compatibility.

Looks cool! Annoyingly less sometimes bugs out and starts spinning, have to kill it from the outside.

It can be tricky b/c Sun's azimuth at sunrise varies by a hundredth of a degree on days directly before and after the solstice.

Wikipedia says it's indeed not a trivial thing

https://en.wikipedia.org/wiki/Solstice#Solstice_determinatio...

there are some observations of mine:

- when the browser is not in the visible workspace, chromium's cpu usage actually goes to 0 whilst firefox's usually oscilates around 5%

- every new window costs 30mb of ram for chromium and 100mb for firefox

- this one is weird, but when lightly using firefox while overall ram usage spilled well into swap, often after some time terminal emulator process will get swapped-out as if firefox eventually touched memory used by every tab sitting in the background

New Glenn has an edge over Falcon Heavy and possibly over Starship when it comes to payload volume.

Most baffling thing is that sometimes you can't opt-out from "always active" stuff that still involve hundreds of "partners"; see: https://news.ycombinator.com/item?id=45844691

If there's no regulation, nothing stops a website from telling hundreds of third-party entities about your visit. No amount of fiddling with browser settings and extensions will prevent a keen website operator from contributing to tracking you (at least on ip/household level) by colluding with data brokers via the back-end.

"Moves are Broken" or why non-destructive moves are at odds with invariants

I can't remember if it was main video or second channel one, in which Alec states with confidence that big brands make powder worse on purpose to push their higher margin pods.

The opinion is based on his experience (horrible residue left by big-name powder in contrast to store-branded great-value powders being problem-free) and lab results.

The sad reality is that easy tech explores solution space faster
