whycombinetor··on Apple to withhold its latest employee perks from unionized store
I've never heard of an individual union member negotiating a higher individual wage or benefits than what's negotiated by the union. My cursory google search results say the same. Do you have examples of this?
whycombinetor··on Students break acceleration world record for electric vehicles
Yes, zero-to-60 (in mph) or zero-to-100 (in km/h) is the standard acceleration measure for cars across the world.
whycombinetor··on What it feels like to be bullied out of a job you love
So you gave your CEO an ultimatum (guy can no longer by your manager or you're out), and then when he does nothing to resolve your situation, you backed down from the ultimatum? There are other robotics companies in the world.
whycombinetor··on Vectors are over, hashes are the future
The article's 0.65 vs 0.66 float64 example doesn't indicate much since neither 0.64 nor 0.65 have a terminating representation in base 2...
whycombinetor··on Many scientists see fusion as the future of energy
Are we talking like Nutty Professor levels of big? Should we be concerned about how big the scientists are getting?
whycombinetor··on Ask HN: Am I the only one who does not want IoT in their solar panel setup?
Are we talking about powering a whole 4 bedroom home? Or just a few panels, a small charge controller, small battery, and like 2000w inverter? Renogy (etc.) sells all of the latter on Amazon that AFAIK don't require any connectivity. But you can't put it in circuit with your house's existing wiring and still be up to code.
whycombinetor··on Artist matches influencer photos with surveillance footage
Is it surprising to find publicly accessible video of yourself on the Internet after you walked through (or spent 30 minutes photoshooting in) one of the most popular tourist destinations in the world? That's all this "controversy" or "criticism" in the article sounds like to me, is people becoming aware of the existence of earthcam.com.
whycombinetor··on Show HN: I may have created a new type of puzzle
I found a state with no legal moves within my first handful of moves - everything on sailboat is irrecoverable. Cool game!
whycombinetor··on GPU mining no longer profitable after Ethereum merge
That's assuming the cost of electricity doesn't go up and the value of POW coins doesn't go down.
whycombinetor··on The dirty secret of mathematics: We make it up as we go along (2018)
Is this still true in hyperbolic geometry, where the circumference of a circle of radius r is greater than 2.pi.r?
whycombinetor··on Lensless camera creates 3D images from single exposure
This technique wouldn't be novel even if it _was_ lensless. Google search "lensfree holography" for plenty of existing literature.
whycombinetor··on Scientists found genetic mutations in every astronaut blood sample they studied
Really? I think everybody in the entire world knows somebody who's died from cancer, and the more educated of those people know that cancer is caused by genetic mutations. Also the theory of evolution is based on random genetic mutations - a very popular theory. I think a reasonable person would therefore know that everybody gets random genetic mutations over time.

To put it concretely, if the chance of a random gene mutation is 10^-4 to 10^-6 per gene per generation, and there are 37 trillion cells in a human body, each cell containing about 20k genes, (all numbers from quick google searches) then the odds of having NO genetic mutations occur in your body in one day would be (forgive my back of the envelope math, assuming a generation is 20 years): (1 - 10^-6)**(37 trillion * 20000 / 365 / 20). My calculator can't keep enough precision to make this nonzero. i.e., everyone has genetic mutations constantly which makes the title of the article completely uninformative.

whycombinetor··on Scientists found genetic mutations in every astronaut blood sample they studied
How am I eliding anything? My statement is that the only quantitative number in the first 2 paragraphs is the ">2%" figure.

I'm also not criticizing the study, I'm criticizing the article and your defense of it. If "you have to use the citations given to understand the broader context of the study" - then if the point of a pop sci article is to effectively communicate the salience of the paper to lay audience, then that broader context needs to be communicated too.

whycombinetor··on Scientists found genetic mutations in every astronaut blood sample they studied
I'm not following several different aspects of your comment here. First of all, the paper is in Nature, not Science. Second, the first and second paragraphs do contain some relevant words, but nothing quantitative - literally the only quantitative number (not nomenclature number) in the entire first 2 paragraphs is CHIP being defined as >2% of something. Furthermore the reference to baseline genetic variation you mention is verbatim as follows: "Considering baseline genetic and extrinsic variability, the development of tools that permit the assessment of individual genetic susceptibility would improve risk stratification and long-term clinical management."

And I would argue that the article (not paper) does _not_ convey the qualitative conclusion of elevated rates of nonstandard mutations, because it doesn't reference the baseline at all! It doesn't even present it as a comparison, like "We found MORE mutations in astronauts than would be expected of non-astronauts" - it literally just phrases it as "We found mutations in astronauts", which, considering that non-astronauts are exposed to radiation and get cancer + epigenetic mutations as well, doesn't differentiate it from the normal expected observation.

whycombinetor··on A few months ago, a complete stranger gave me $10k (2021)
From what I can gather from the twitter hashtags, the "report back on how it was spent" requirement effectively shamed the recipients of these TED grants into using it on almost entirely charitable ends. Not a bad thing I guess.
whycombinetor··on Illustrating Gutenberg library using Stable Diffusion
Index funds hold underlying assets under management... You are paying for a slice of the underlying assets... All slices of the pie are accounted for and it doesn't create anything new. Not sure how that relates to machines reproducing human creative efforts.
whycombinetor··on Teenager invented a low-cost tool to spot elephant poachers
If you are flying a drone overhead, you know the altitude and can do basic trig to find total distance from sensor angle. With even very approximate distances one should be able to distinguish a 200lb, 0.4m wide, 0.2m long human from a 10,000lb, 1.5m wide, 4m long elephant.
whycombinetor··on Teenager invented a low-cost tool to spot elephant poachers
Surely you can discriminate a human from an elephant _by size alone_ with a thermal camera, without needing to resort to movement patterns.
whycombinetor··on Tell HN: Heroku alternatives with generous free tiers
Is Elastic Beanstalk so far out of fashion now that people have forgotten about it?
whycombinetor··on Ask HN: DALL-E was trained on watermarked stock images?
Precedent in music says sometimes-yes. The "Blurred Lines" lawsuit found that Pharrell and Robin Thicke were liable in the tune of $7m for producing a work of art solely from memory that copied the "signature phrases, hooks, bass lines, keyboard chords, harmonic structures and vocal melodies" of a Marvin Gaye song. https://en.wikipedia.org/wiki/Pharrell_Williams_v._Bridgepor... https://www.npr.org/2015/03/11/392375390/-7-million-verdict-...
whycombinetor··on Let’s Not Have a Beer
> Imagine going to a meetup or work event where everyone is smoking weed and they’re discussing how to grow good quality cannabis. If you are not a cannabis user, you will feel out of place at that event.

Therefore - no more discussion of any hobbies at work or meetups!

whycombinetor··on An odd discovery on Spotify
Just opened youtube.com and 6/8 of the videos on the top section of my front page are from channels I'm subscribed to. That happens for me every time. Sorry your subscribe button doesn't work.
whycombinetor··on Is There a Curse of the Fields Medal? [pdf]
Or maybe, after receiving the Best Mathematician of the Year (Under 40 category) award, since your desire for social recognition of your supreme genius and success is now undeniably fulfilled, you start to realize that you can adopt a new healthy focus on some other aspects of life too, so your late career publications and fame burn less intensely than your supernova early career?
whycombinetor··on US Mortgage Lenders Are Starting to Go Broke
No, the point is that from the seller's point of view, the return on a sold loan/pool is higher than if you kept the loans, because the buyers pay a premium for the privilege of buying, and that premium goes straight into the seller's pocket. Then they will use that pocket cash to go buy some (% of) other loans from originators in different industries / different geographic locations / other different characteristics that they can't originate enough of themselves to have a sufficiently diversified portfolio to satisfy investors and board members who are risk averse. It is not about passing off the risk entirely (credit unions have to retain at least 10% ownership for themselves, for example), since you are still going to buy % participation in other loans that have risk, but about trading out a large investment at a lower return for a smaller investment at a higher return.
whycombinetor··on Using strangers to explore the city (2018)
Is it just me who thinks it would be relatively easy to notice someone intentionally following you at the same pace and distance on a given walking route through your home city? Stop to look at the flowers a few times and notice that they always stop at the same time as well...
whycombinetor··on Mary Schmich's “Wear Sunscreen”, which turned into an unlikely 90s hit (2019)
The comments here feel weird now, after changing the target link of the post to an article not focusing on the song, when the majority of the top level comments are about the song. The new link barely mentions the song twice.
whycombinetor··on Airbnb will up its penalty for hosts who cancel last-minute from $100 to $1k
Extended Stay America locations have a "fully equipped kitchen" in every room so it's certainly possible and already happening.
whycombinetor··on China mortgage boycott data erased by censors as crisis spreads
Thank you - indeed I should be comparing against https://fred.stlouisfed.org/series/QBPLNTLNNCUR which is only 0.8%.
whycombinetor··on China mortgage boycott data erased by censors as crisis spreads
The US mortgage delinquency rate was 2.13% in Q1 2022 ( https://fred.stlouisfed.org/series/DRSFRMACBS ). It was 4% in 2016, 3% in 2018. Why should an observer/investor be worried that "Non-performing loans [...] could reach as much as [...] 1.4% of the outstanding mortgage balance"?
