It's not harsh to me, since you are critiquing the work of some of the best experts in the world, not me. What do you mean by "reorder matrix multiplies in a source-to-source transformation?" To be clear, the issue is that m

I strongly disagree. Bitwise reproducibility would make it impossible to change or improve matrix multiplication algorithms, since the order of operations matters, and will change across implementations. Do we really expect everyone who do

Libertarians don't have a monopoly on free market thinking. Most mainstream (non-libertarian) economists would have said the same 50 years ago.

Another related fallacy I see all the time is dismissing a problem by inventing a terrible solution. E.g. Climate change is real -> "So you are saying we should just shut down all industry and go back to the dark ages" The esta

I don't know if the popularity of this on HN is a case of the emperors new clothes, or if I am really missing something, but to me this is sophomoric. There is nothing inherently base-10 to finance or any other field. Finance deals i

Do medical providers focus primarily on how people feel they should be treated, or clinical outcomes? Does the FDA ask people whether the would like to live longer before crafting its dietary advice? Do macroeconomists ask how important j

Hitler was wrong in his opinion that Jews exploited the economic system for nefarious means, or that Jews were entirely in control of the international politics. On the other hand, he was correct that Jews (both as individuals, and through

I especially like how it explains the meaning behind the oft repeated mantra that cancer is not a single disease, or that cancer is not a single disease therefore there will never be a cure for cancer. Both these statements reflect true fa

That's why Intel devotes large part of the CPU to the embedded GPU -- it doesn't have much else to do with it. I don't quite understand your point here, but if you were intending to refute my point regarding GPU computing,

Re Moore's law, the best answer I could get was from Intel via Wikipedia[0] "our cadence today is closer to two and a half years than two." So I wouldn't call that "stopped" but slowed. On the other hand, the

I can't remember (possibly not Greg Egan). In case someone else knows, the main plot is that the characters have to act as inhabitants of a primitive village, in a computer game/simulation.

It's fascinating that this is so close to reality, at least in terms of preserving the information that encodes our memories and identities. Of course there is the issue of reviving the person, either biologically or digitally. As com

On the flipside, what if Caucasian [sic] men were better than everyone in this field? Many people are happy to assert that diversity is good because it means multiple different viewpoints. What if the viewpoint of the Caucasian male[0] ha

Before anyone critiques this site, I'd urge them to read the entire front page of their site. In particular: Tell navlio the companies you like and it will apply machine learning to match your views with like minded fund managers and

This is an interesting idea, but one source of bias that troubles me is that after people have received a nobel prize, it might bias how they are characterized by themselves or others. Maybe being a "famous person" makes us chara

If no ISP will host your content, then your message cannot reach anyone, and you effectively have no freedom of expression. I wonder why you oppose government censorship, if you applaud private businesses achieving the same effect? Certa

I think 20000 lines of code is the tipping point where code bases go from applications/libraries to frameworks. The difference is that the objects of an application/library are expressed in the raw language, while in a framework

Are you saying that in order to not be a chauvinist, one must agree with any claim about the achievements of any woman born before 1969 (or wherever you happen to draw the line). If you are simply saying that one must take the sexism of

Yes, but being a martingale implies something stronger, which is that both short and long term traders are betting on the fundamentals to exactly the same extent.

If you knew anything about academia, or if you even bothered to carefully read my post instead of nitpicking, you would understand that just because something is in general true, doesn't mean that there won't be hundreds of pape

But people who trade against fundamentals aren't trading directly against future profits, they are just betting on long term price movements. HFT traders are betting on (very) short term price movements. According to the theory that

One mechanism that I find very striking, is when journalists make the choice between stories like "X says Y" vs "X refuses to apologize for saying Y".

I'm assuming the downvotes are because claims like this are very common, and without some kind of presentation of evidence, and discussion of the explanation (if any) given by Google, they just become background noise in any discussion

As someone who completed a PhD and knows many people who went on to academic positions, there tend to be three stages for people who come to accept the status quo. 1. A desire to make big breakthroughs in the field. 2. A frustration with th

I think that it's fair to analyse the author's success or lack thereof, because he relies on this as part of his argument, e.g. My friends have also pointed out that I should not be "discouraged" by the difficulties fac

It's not fair to twist people's words like that. If the poster meant churning out papers by "good work" then the whole post would not make sense. A much more reasonable interpretation would be "in order to produce

I agree. While I'm not very pro copy-left in general, I think for a social network it makes more sense. If there are concerns about privacy, and the solution is open source, then why leave the door open to a proprietary version tha

I agree with the sibling comment[0] on the interpretation of Feynman's quote. Also, rejecting the usefulness of philosophy of science doesn't imply accepting the view that the scientific method can and will describe the purposes

Having taken a few (graduate) courses in development economics, I've decided that development is not for me, and my skills simply don't apply. I think the same applies to most people in tech. As the article points out, there are

Indeed, and modern economics as a discipline goes out of its way to keep everything finite. I was going to post the same thing: that the finite version solves this problem completely. The only case where economics cannot avoid dealing with
