galcerte··on Deuterium molecules in superposition act as slits for classic quantum experiment
More or less, yeah, because you can measure the molecules' spin and figure the spin of the previous state using conservation of total angular momentum (which is equal to spin + orbital angular momentum, if you know the latter, you can figure out the former...).
galcerte··on Flatpak Is Not the Future
> This OTOH does not exist. Linux gamers are 1% of either the gaming market or the desktop computing market. All gamers either dual boot windows...or android. Even for those who game on Linux, they do it on an abstraction layer like Wine. Which is what Valve maintains

First off, 1.13% of Steam users are on Linux [1], and given how many users Steam has, just 1% of that population should be able to make quite a fuss. Secondly, Valve does need those containerized runtimes even if most games run on Proton, since Proton also depends on those libraries, so not sure why you're dismissive...

The UHK and the ErgoDox are the two most prominent preassembled ones. The former is out of stock, though.
galcerte··on Megaprocessor – A micro-processor built large (2016)
In that case, if you want a somewhat entertaining very-high-level overview of what would need to be done, then there's a manga that showed this off a few chapters ago, it's called Dr. Stone. What stuck with me the most was that the purity needed for the silicon used in processors was absurdly high, so much so that they couldn't quite do that just yet, so they made a processor out of parametrons and used magnetic core memory. I knew semiconductors had to be very pure, but it was a bit discouraging to realize just how much effort it would take if you started from zero.
galcerte··on Mysteries the Standard Model can’t explain
We have detected the effects of gravitons (...if it's gravitons and not something else) at macroscopic scales, however we have not done the same with monopoles. So that comparison is not apples to apples.

I have not heard anything about the SM predicting them being impossible, but I assume it does given that I haven't heard anything about the subject. Source: I have a master's in physics and a friend of mine did his bachelor's thesis in monopoles in classical electrodynamics (albeit modified) and his master's in quantum ones, so he would've told me if he knew.

However, if any GUT theory we have come up with is correct (because a few exist), then that does imply the existence of monopoles.

galcerte··on World’s first USB-C iPhone sells on eBay for $86,001
Isn't wired charging faster than wireless? And isn't wireless charging less efficient, too? You're bound to lose some energy unless you really focus the radiation that's emitted.
galcerte··on DARPA has caught a Gremlin drone in midair
These drones look virtually identical to some cruise missiles. I wonder what this would entail for the defense of whatever airspace they enter. Seems like these could be used as somewhat cheap decoys.
galcerte··on Why Is German Internet So Bad
European landline internet almost never has data caps.
galcerte··on C³: A "cool" route to the Higgs boson and beyond
We believe we should have new physics at higher energies because treating the SM as an effective field theory introduces additional terms in the Lagrangian which are suppressed (~ divided) by some energy scale. These additional terms are the ones allowing lepton flavor violation (so a muon decaying to an electron and a photon, for example) but we know from experiments that these events are incredibly rare. This tells us that the energy scale of new physics is very high.

However, we could also have new physics at lower energy scales, as is the case with axions.

galcerte··on Ask HN: What questions are you searching answers for?
Doesn't the answer to "Why isn't China (yet) producing a lot of top-tier research?" have something to do with the large language barrier? I did hear that English is taught as a second language in Chinese education, however couldn't it be that most of these papers are being published in Chinese and are consumed nationally?

This could be made worse by non-Chinese nationals not wanting to learn Mandarin et al. as much as other foreign languages.

galcerte··on The FBI's internal guide for getting data from AT&T, T-Mobile, Verizon
I'm not so sure about that. I've been seeing it around more than I'd like recently. I even had to use it to talk to my thesis' supervisors.

Slide is also a great FOSS Reddit client on F-Droid, with a subreddit at /r/slideforreddit as well.
galcerte··on Cannabis and Male Fertility: A Systematic Review
I'm seeing the opposite quite often where I live, people who are quite a bit into weed usually end up needing to bake in order to sleep more comfortably.
galcerte··on Trustworthy Computing in 2021
I thought something along these lines when it comes to peripherals, too, but don't these (mice and keyboards chiefly) communicate with PCs through a subset of the USB standard which only handles HID and nothing else?

Would any snooping be possible through an input device if it only did HID?
