Of course you should but the blocking and amortization techniques have much wider usecases beyond linear algebra. Matrix multiplicaton is a useful "simple" example to study; of course you don't write your own if what you want

For programmers, the really interesting part of dense linear algebra is how to achieve high performance, as blocking techniques have to be used to amortize loads from memory to cache. Google for Goto's "Anatomy of high-performance

Because the people you pay could just take the money and then cast the (secret) vote the other way. Secret voting is what prevents buying votes today.

Noone is talking about it because the fix is obvious: If you have secret votes then you can just take the money and vote the other way. Which is what prevents this today.

I agree to focus most on the meat, mainly because it takes 10x the resources per pound to produce compared to vegetables, so it's the most valuable resource.

It's more that if you use the rest of the food the next day, you will consume less new food the next day, and thus consume less resources, and a little less resources is spent on food production. A staggering 50% of the food produced i

The morally wrong part is with not finishing it later. Stick it in the fridge and eat it for lunch or evening snack next day. Or make a meal which includes the leftovers as ingredients (leftover pasta sauce goes as pizza topping, and so on)

IMO throwing away good food is morally wrong. Luckily there are movements ("food redesign" etc) that try to reverse the trend.

My reaction to the insect in flour info is "yay more proteins". Why would one try to avoid it? I mean on a scientific level.

The limit is very high because it is not just the current pooulation, but all the new housing that is also induced. Where people live is a functon of transportation.

"The argument, the subject, really is just that simple." I almost lack words at this point. I hope you never come in a decision where you need to judge a scientific inquiry in a way that has consequences for others. At least not a

I think the reference to "pre-modern" is referring to your (over-)confidence in having realized something very simple, simple enough that a 10 paragraph post on HackerNews can possibly put things straight, and then the arrogance i

Thanks for the thorough explanation. Do you have sources? I want to read papers, I don't want to read your unsourced statements. Can you post links to any peer-reviewed papers supporting your claims? Or, if there is a big conspiracy no

This would have been so cool as a book! (Any recommendations?) I lack the patience to watch YouTube videos though...

I am curious: Can you define a set of measurements and a year which, hypothetically, if measured, would convince you that global warming is happening? I.e., if we were to make a bet that both you and an IPCC-groupie like me would be convinc

It is not GAE but Google Cloud DNS right? So one needs to write a small app that uses that API to answer the challenge.

I am not against nuclear, just want to point out that while this might have been true in the past, the price decline in solar means nuclear now looses on price. (Perhaps as stable base load where hydro is not already in place...but energy s

Same in some parts of astrophysics. The real peer review is social, you review when you cite so to speak, if you cite garbage then your work turn into garbage, so.... journal peer review is just an after-thought to collect points for fund

All the examples you mention are on the "futile" side of actions to take though. Like, if someone is driving a fossil car anyway, sharing a ride is very eco-friendly. There is very little extra CO2 emitted by you getting into the

The problem is not communication. To quote Paul Graham in a keynote from some years back: People have been waiting for "sufficiently smart compilers" to cut programmers out of the loop for 30 years. It is a neat idea in theory. In

I think the parent with "satisfactory" meant "possible to achieve the maximum performance the hardware will support" (after all why settle for less?) You are answering another question. Also, the point where you have reo

Well, the compilers don't do a good enough job, end of story (at least using C; not sure about OpenCL). To achieve top performance it is necessary to make sure everything in the computation is organized in the right way. And try out mu

I tried to rely on your first bullet point and randomly end up with BigQuery surpassing some API treshold towards Drive (paying customer). Have to carefully manage doing copy-queries over to BQ, which is a pain, but better than nothing I gu

What you mention are circumstances and excuses that doesn't change anything. The point of the parent post was that in some countries (mine is Norway) you just don't do it, full stop. Very hypothetically, if someone else got you dr

Once a species is gone it is gone. Lots and lots of species disappear now and many of them we are not even aware about, let alone any DNA samples taken or research done (e.g. burn down rainforest). So you can't "have both".

Thanks for the reference to Edgar Allan Poe's essay on the Mechanical Turk, that was a fun read. So right about some things and so wrong about others :) """ The Automaton does not invariably win the game. Were the machin
