dskrvk··on Ultrasonic Chef's Knife
I like this vibro-knife “demo” by Neil Blompkamp’s Oats Studios: https://youtu.be/zaeFgSR_DMU
dskrvk··on The Crisis of the University Started Long Before Trump
> And for another, in the process of seeking to maximize its gain from technologies discovered in its labs, the University of Chicago now does more than participate in licensing. It actively invests in start-ups by its faculty, millions of dollars in dozens of investments. Quite apart from the fact that these investments have mostly been a bust, the practice raises serious questions. Can a university make rational decisions about the value of a given employee when it co-invests in commercial ventures with that employee?

> And more seriously, where does the money come from? Is the university driving down what it spends to educate its own students so that it can use unrestricted funds to invest in startups? Or is the university functioning as a kind of tax-free pass-through organization? Does it receive third-party money that it invests as a tax-free enterprise, to the benefit of other investors in the same start-up?

> Spending as little tuition as possible on educating students, and (instead) investing in start-ups ... This is why I say the University of Chicago’s leadership and trustees run it as a tax-free technology incubator. All of which raises the question, whether an operation of this kind deserves the status of 501(c)(3) charitable organization.

dskrvk··on Exploring the Paramilitary Leaks
The guy is just walking us through the process of analyzing the dataset. He’s not really making any conclusions at this point - it’s like a technical tutorial for journalists.
dskrvk··on Is the world becoming uninsurable?
Bloomberg recently did an excellent series on just this issue (including insurers of last resort in different states). The first part: https://www.bloomberg.com/features/2024-home-insurance-real-...
dskrvk··on The Weeds Are Winning
Bruce Sterling’s “Heavy Weather” describes (offhandedly) a post-agricultural ecosystem where only herbicide/cold/heat-resistant weeds remain. People then breed genetically-engineered livestock that can convert the weeds into more useful substances.
dskrvk··on The Friendship that made Google huge (2018)
It elevates Google itself. “It’s a place where people like Jeff and Sanjay work!” Not saying that was the main motivation for producing the article and definitely not trying to question the protagonists’ achievements.
dskrvk··on AI-powered music scam nets musician $10M in royalties–and federal charges
He didn’t generate the music himself, and likely worked with others on setting up the bots (the article mentions co-conspirators). On the song generation:

> This led Smith to pivot to AI-generated music in 2018 when he partnered with an as-yet-unnamed AI music company CEO and a music promoter to create a large library of computer-generated songs. The district attorney announcement did not specify precisely what method Smith used to generate the songs.

I wonder what company he used and whether they can be liable too.

dskrvk··on Please do not attempt to simplify this code
But comments go out of date, and the compiler doesn’t check them against the implementation. To document + enforce the intended functionality, use tests.
dskrvk··on Boeing Starliner launches first crewed mission
It’s also surprising that BBC, a government-funded media outlet, is showing ads. Either the government funding isn’t enough or they are trying to recoup some of those costs by showing ads to people who’ve already paid for the content with their taxes (even the international part is paid for - see below).

> Its work is funded principally by an annual television licence fee which is charged to all British households, companies, and organisations using any type of equipment to receive or record live television broadcasts or to use the BBC's streaming service, iPlayer. The fee is set by the British Government, agreed by Parliament, and is used to fund the BBC's radio, TV, and online services covering the nations and regions of the UK. Since 1 April 2014, it has also funded the BBC World Service (launched in 1932 as the BBC Empire Service), which broadcasts in 28 languages and provides comprehensive TV, radio, and online services in Arabic and Persian.

dskrvk··on Visualizing algorithms for rate limiting
> add a deterministic offset to each user/session window so that no large group of rate limits can expire at the same time

Did you mean non-deterministic (like jitter)?

dskrvk··on We've already seen category 6 hurricanes – scientists want to make it official
This is exactly the premise of Bruce Sterling’s novel “Heavy Weather”.

dskrvk··on Free Download Manager backdoored – a possible supply chain attack on Linux
Yes, if they’re unwilling to show a small detail like this due to sanctions that the Russian government supposedly would rain on them in retribution, one wonders what else they’re unwilling to disclose from their other investigations for the same reason.
dskrvk··on Landauer's Principle
Here’s a recent quote from Scott Aaronson:

> In truth, anything that a QC can calculate, a classical computer can calculate as well, given exponentially more time: for example, by representing the entire wavefunction, all 2n amplitudes, to whatever accuracy is needed. That’s why it was understood from the very beginning that quantum computers can’t change what’s computable, but only how efficiently things can be computed.

dskrvk··on Programming AIs worry me
An AI that tells whether or not a program will halt.
dskrvk··on Junkyard computing – repurposing discarded smartphones to minimize pollution
Same here, replaced my old 8 last month, but only because a few rows of pixels went bad, not because of compatibility issues.
dskrvk··on Gmail 2FA causes the homeless to permanently lose access 3 times a year
Lower in the same thread: https://twitter.com/chadloder/status/1577906942080598017?s=6...

> PS: Many unhoused people access their email rarely, intermittently; they don't stay logged in. They often have to guess several times to remember their password.

2FA doesn’t work, and remembering passwords doesn’t work either. Checkmate.

dskrvk··on VCs squandered billions on scooter startups
Yup, they were especially great during the fuel shortage days when car traffic mostly ceased.
dskrvk··on About Time (By Isaac Asimov)
The first story in this issue, Crazy Maro, is by the author of Flowers for Algernon (https://news.ycombinator.com/item?id=31875692). Both great stories.
dskrvk··on Driverless robotaxi fleet paralyzed for hours in San Francisco
Philly did this too, though in the recent years the city started bringing some lines back. Heck, when the full tram network was around a 100 years ago, it could take you pretty far out into the suburbs, while today you either have to take the train which comes every 30-60 minutes or drive.
dskrvk··on The Magnetar, nature’s ultimate superweapon
They probably can’t produce enough AM to power them autonomously, so still rely on stellar radiation. More importantly, it’s kind of fun to have a large star in the sky.

That’s why in The Culture sensible people live on orbitals.
dskrvk··on Show HN: IoT device to warn you of a supernova hours before Earth is destroyed
How would one even test a feature like that?
dskrvk··on Show HN: IoT device to warn you of a supernova hours before Earth is destroyed
But that would create a mass panic, while this device lets the owner quietly proceed to their private shelter without alerting the neighbors.
dskrvk··on Ask HN: Anyone else quickly losing confidence in Amazon?
> Lots of returns end up in the trash too.

Yup, apparently until recently Amazon didn't bother finding a new buyer for the returned products and simply trashed most of them. Now there's a cottage industry of people buying returns in bulk, sorting through, and reselling the quality stuff (kind of like the industry around auctioning unclaimed storage unit contents). However, I imagine that many cheap products even now don't go through the auctioning process and go directly to waste.

dskrvk··on Does Not Translate
The Polish word https://doesnottranslate.com/kurwido-ek/ seems like a great explanation for why some people took too long to leave, as described in the neighboring “Great Resignation” thread: https://news.ycombinator.com/item?id=29937305
dskrvk··on Ask HN: Is hidrb.com legit and how can I tell?
They appear to be: https://www.nytimes.com/2021/03/09/health/covid-vaccine-left... The lack of mainstream coverage was intentional (I guess they've decided it's time to go wide):

> Mr. Massoumi said he had taken several steps to ensure that the service will be equitable. That has included turning down early media requests from mainstream publications and instead promoting Dr. B on Zoom calls with representatives for groups like Black churches and Native American community groups, given that the pandemic has disproportionately affected nonwhite groups.
