notfed··on 'Cosmic radio' detector could discover dark matter within 15 years
Had we named it "invisible matter", perhaps not as much controversy would surround it.

This seems to be an analysis of chords used, not chord progressions?

It's really hard not to devolve into a giggling teenager with this headline and how perfectly it conjures up what is perhaps the most memorable Sunny in Philadelphia episode ever made.

Sadly this prediction could have been generalized to the US executive branch regardless of the most recent election. It's more of the same from what we've seen in the past, Democrat and Republican leader alike.
notfed··on AI cheats: Why you didn't notice your teammate was cheating
For a single player game, that might be a good explanation.

For a multiplayer game, though, it's not hard at all to see what's happening. If a cheater cheats and gets away with it, then they rationally should expect to receive social reputational credit, which I want to believe is something that instinctively makes most of us feel good, us being social creatures.

notfed··on Convert Linux to Windows
> Thesis: We should create a distro of Linux that runs Windows binaries by default via Wine.

On Debian you're one package away:

    sudo apt install wine-binfmt
Otherwise you're still pretty close:

    echo 'none /proc/sys/fs/binfmt_misc binfmt_misc defaults 0 0' >> /etc/fstab
    mount -a
    echo ':DOSWin:M::MZ::/usr/bin/wine:' > /proc/sys/fs/binfmt_misc/register
notfed··on Xee: A Modern XPath and XSLT Engine in Rust
> It does not wipe out whitespace just on its own.

Sounds nice but doesn't match my lived experience with both Chrome's built-in XSLT processor and `xsltproc`. (I was using XSLT 1.0, for legacy reasons, so maybe this is an XSLT 1.0 issue?)

> Do you mean that you'd like facilities to nicely reindent the output?

No, I do mean preserve whitespace (i.e., formatting), such as between elements and between attributes.

notfed··on Blockchain with Proof of Quantum Work
> By replacing classical machines with quantum systems for mining, it is possible to significantly reduce the energy consumption and environmental impact traditionally associated with blockchain mining

I don't think that's even theoretically true.

The amount of energy miners burn is driven primarily by one criteria: how much energy they can afford to burn. And since blockchain is a competition, miners will burn as much as they can afford to.

So let's say we're environmentally conscious people and designed a blockchain hash algorithm that's 1000x more efficient and got everyone in the world to switch to it. Would that save us 1000x more energy? No, we'll still burn the same amount of energy.

Another criticism: I fail to see why we'd need to "require" quantum computers for the blockchain. In this theoretical era where quantum computers are commoditized enough for everyone to have one, miners would already be incentivized to use a quantum computer, simply because they'd make more profit using a quantum computer than using a classical computer.

notfed··on Xee: A Modern XPath and XSLT Engine in Rust
Does it preserve whitespace? Something that I always found asinine about XSLT is that it wipes out whitespace when transforming. Imagine you have thousands of corporate XML files in source control, and you want to tranform them all, performing some simple mutation. XSLT claims to be fit for this job, but in practice your diff is going to be full of unintentional whitespace mangling.
notfed··on It's Time to Stop Building KV Databases
Never believe that any tool is good or bad. That's always going to be a generalization, and therefore wrong. Learn as many tools as possible, and know which use cases they're good at and which use cases they're bad at. If someone implies the tool is bad for all use cases, know that we all live in our own bubbles and are ignorant about the plethora of other use cases that exist in the world.
notfed··on CO2 laser enables long-range detection of radioactive material
There's no claim of a new discovery here, just an impressive feat of engineering. Remember that nuclear fusion is also pretty basic.

It's also widely known to cause headaches. I swapped out all my PWM bulbs and couldn't be happier. More info here: https://flickeralliance.org/
notfed··on My stupid noise journey
> I am looking for similar but dont like headphones pressing on my ears.

I have both noise cancelling "big" earphones and earbuds. I agree with you that the the "pressing on the ears" is annoying, so I usually wear the earbuds: the noise cancelling is slightly worse, but the latest noise cancelling technology is really good enough.

notfed··on Ask HN: Do your eyes bug you even though your prescription is "correct"?
The term to Google for this is "vision therapy": there are several tried and true exercises.
notfed··on Ask HN: Do your eyes bug you even though your prescription is "correct"?
This is part of what's referred to as "vision therapy". Optometrists would tell you to go to a paid expert---because purportedly some people do it wrong---but IMO you can just YouTube it.
notfed··on Ask HN: Do your eyes bug you even though your prescription is "correct"?
This is called the 20/20/20 rule: every 20 minutes, look at someone 20ft away (or just close your eyes) for 20 seconds.

I wouldn't call it "the" solution: it's part of a complete breakfast.

notfed··on Ask HN: Do your eyes bug you even though your prescription is "correct"?
Wow...thank you for this phrase. I always thought it was impossible to find prescription lenses online, and there's a box with literally all of them...
notfed··on Ask HN: Do your eyes bug you even though your prescription is "correct"?
Or using dark mode. There are chrome extensions that force dark mode on every page.

I personally can't last 1 minute on a white screen, and bringing brightness too low isn't without its issues.

notfed··on Ask HN: Do your eyes bug you even though your prescription is "correct"?
Same here: it's called "accommodative excess". And in particular, it won't show up on a vision test.

I always got 20/20 on my vision tests, but kept complaining to different optometrists, and finally found one smart enough to recognize my situation, and now I wear -0.5 lenses. It brought my life out of a very dark place.

notfed··on Ask HN: Do your eyes bug you even though your prescription is "correct"?
PWM is a real concern that impacts, say, 10% of the population, and probably only 0.1% are aware of it. It's been a growing, silent epidemic due to a very clear culprit: OLED screens, particularly on cell phones.

Phone manufacturers know that OLED screens cause eye strain, and they've tried to mitigate it, but it's still sort of an unsolved problem that phone manufacturers haven't prioritized. For the most part, they tend to prioritize making the problem worse over time.

A quick intro to the topic: https://flickeralliance.org/pages/about-flicker

Personally, I am grateful to have an LCD laptop (the MacBook M2 Air's screen is a godsend), and I hope more people would recognize OLED PWM as the source of their eyes strain and complain about it, so that manufacturers change their priorities.

notfed··on TypeScript types can run DOOM [video]
> "It was a brutal year long journey of 18 hour days" [to run doom in TypeScript types]

This is some serious dedication for what at first blush may sound to many to be a completely unserious, or even useless, achievement. But I say to those people: a DOOM proof is just as worthy of praise as any other academic mathematical proof, and has the advantage of being verifiable by laymen.

Congrats on this amazing achievement.
