Gcc collapses acos(cos(x)) to x on -O2? Surely not since this isn't even accurate for x outside of -pi to pi. That's ignoring floating point errors that make those two different which I thought was a different optimization flag,

You cut out the "had any kind of mass market appeal" part, which makes the claim much more plausible (though I couldn't rule out there being earlier examples too).

I figured these were a step further towards MLM: a single company selling individuals signs and a generic dating site for $3000 or whatever and promising them a portion of the proceeds. That way the central company never has to plant signs

This is fantastic! Not sure how I was unaware of this.

Re: taxpayer dollars, note that in the US the NIH is the latest source of public funding for research and requires open access publishing these days. The NSF (which does not require open access) is considerably smaller, as are all other fun

I just had a project where we need to keep track of changes to a string as a series of insertions, deletions and substitutions. We don't want the whole history, so if someone inserted then deleted the thing they inserted, we would trac

Are those just black tiles or are they black noise reduction tiles? I don't see any indication of the later. Is vinyl a common material for noise reduction?

I can't imagine what you mean by historically accurate with regards to tales of near-immortals, gods, monsters, etc. How could archeology show the story of one man's voyage to be accurate, let alone the sirens and cyclops that he

Bufferbloat.net talks about this. The problem is that many home routers do a poor job allocating their resources so if I'm streaming video and you're VOIPing, your latency will go up dramatically since my download is pushing you o

Electronic records have a single point of attack for the entire country's data versus a breach at your local hospital. Makes beaches much worse while also greatly incentivizing the breach.

Also satellite dishes point roughly south if you're in the northern hemisphere. (They point towards geostationary satellites which have to be over the equator.) This is a more useful tip in some places than others.

I was under the impression that the military and maybe other branches of the US government have "no East Egg" rules for software they use, and I expected that to be the justification. Is this true? I found one document from a .mil

Love the game. What's a good solution to the increment gate? My answer worked but seemed way too complicated.

Thanks. This reminds me of the part of "Surely You're Joking, Mr. Feynman" where a painter says you can mix white and red to get yellow and Feynman says it's impossible and it turns out the painter would use a little bit

Can you elaborate on why your don't get grey? That was always what I expected and I was surprised that you just get a muddy brown if you mix random paints.

It's okay about the downvotes. Completely bizarre though: my comment was originally at +12 and got down to -2! HN is just inscrutable at times. I feel like the initial upvotes show that I was not alone in thinking his story is surprisi

I agree. Her reaction was ridiculous and aggressive and was done in public and in reference to her work. Her employer absolutely should have disciplined her. However, the increasingly aggressive presence of internet mobs saying "fire t

Well now I have Cybernazi in my Youtube history, guess I should read the article before clicking the Youtube link and then blithely clicking "okay" on the notice informing me that the video content has been flagged. Though I'

No, I wasn't. You can see in my original one that I cited The Guardian's coverage that was original story as well as all the tweets they listed there (praising the rescue work - I'm completely shocked they weren't mentio

I see, I was probably not paying attention to the story at the time. I still find it odd that these summary articles after the fact seem to be ignoring the fact that one person died during the rescue attempt. I'd have expected more &qu

Why wasn't the death of Saman Gunan more widely publicized? I barely heard about it - in the NYT article on this it's a single sentence 2/3rds of the way through the article. I'd have thought that the concept of someone

I did a PhD in math and if I were to do things again, I'd do applied math because I think I enjoy applied math at least as much as pure math (this is not true of everyone) while also having it have more obvious job prospects. I did p

Thunderbolt 3 is certainly enough - see its use in eGPU setups. (My understanding is that this actually runs PCIe lines over it.)

The difference to me is whether they list all the bugs (while suggesting that their product would help) to the developer before publishing or not. If the only way to satisfy them is to pay, then it's incredibly scummy and moreover is a

I think Doctorow's analysis makes more sense than the typical rhetoric about Facebook and CA. But I still default to thinking that CA was largely ineffective. How many "latent klansmen" were there unaware that Trump was more

I don't think that helps significantly. Check out the plot on Wikipedia [1] for the ultraviolet index in NYC. At peak on summer, solar noon versus 8am there's a factor of ~3 difference between UV incident on a horizontal surface.

Do these use a SIM card? Thought they were satellite. That's what the first thing I googled seemed to agree with too ( https://www.yachtingworld.com/features/epirbs-plbs-and-man-o... ).

Note that the bufferbloat choice for me is whether or not I want my packets to arrive 1.5 seconds late, not 30ms.
