Doing anything repetitive with a large amount of data by virtue of knowing about for-loops. There have been so many times where people wanted something done to a million users/objects/whatever and were surprised that I got back in

One of the biggest lies in cultural thinking is that countries like Ireland and the UK are "culturally close" to the USA. Sure they are close-er than say Italy or Japan, but anyone who thinks "close" means "similar

First comment on the answer: > This is quite the most extraordinary stack exchange answer that I've ever seen. And I couldn't agree more. Well worth perusing if you (like me) usually only check the comments on HN.

It's entirely possible to just stick your files in dropbox or something like that and they sync just fine.

The original dog would still die, no? Having a puppy with technically the same genes but none of the behaviors or memories of the original seems like a very poor substitute.

So it does. That was not an option in GPs post though.

There's lots of space up there though.

Trick question! Space based solar derives all its energy from fusion anyway.

It's a demonstrator, trying to verify that the technology can work at all. The real version would be sent out to an orbit where there is always a direct path to the sun, but sending out spacecraft that far is much more expensive than j

I see what you mean but there's a huge gap between a "good enough" mental model of how computers work and the actual in-depth details that GP means and that have been successfully abstracted away from us. For example: the amo

This is wild to me. I've applied to 4 jobs in my life and been hired for 3 of those. I can't imagine having to write hundreds of individual cover letters. Is this one of those US vs EU differences?

This in itself proves nothing. Consider how much resources have been poured in making rockets better over the last few decades and yet we still can barely make it to Mars. It is also quite possible that there are fundamental limits to sca

Why would a language need a specific reason to exist? It's a nice language with Ruby-ish syntax, strict typing, a go-like runtime and it compiles down to something quite fast if you take a little bit of care.

Speak for yourself, there are dozens (dozens!) of us for which recursion is the more natural way to think about most algorithms. Joking aside, DP is very straightforward in more functional languages like Haskell where recursion is the defau

I personally don't think this is very likely (main question: how do they actually manage to get those planets paired and ejected in the first place??? The energy requirements are quite literally astronomical) but it is a very cool idea

Or to skip the co-op system entirely because it doesn't work all that well in practice.

Yes fun joke, but it's literally one plane out of thousands produced and everyone survived. FWIW, the bleed air systems kept working perfectly so they had plenty of pressurized air inside.

It is already a game of cat and mouse and has been since forever. There's nothing wrong with cat-and-mouse games from the viewpoint of an advertiser, it just means they have to keep innovating.

The web was invented in 1989, so mostly it didn't. Before that there were BBSes that you could dial into. From there, you could chat with other users who happened to be logged onto the same server or download text documents and whatnot

1. Air planes are full of pressurized air, hydraulic and fuel systems already, and they fail very rarely indeed. 2. Aircraft control surfaces are quite a bit more involved than being "a simple mechanical flap".

I think GP meant that they might give more of a fuck (in the wrong direction) if sabotaging "just this one bolt" means this they can own a significant chunk of stock in the company they are part of. According to a quick search Boe

Sorry but this is a garbage tier article. The research showed making carbon-based supercapacitors out of hemp waste products, which are not and will never be a replacement for the role that li-ion batteries have today. Their energy density

Is there ever a reason to use an INT these days? If you do have a lot of rows, you need BIGINT anyway. If you don't have a lot of rows, the few extra megabytes of disk usage from INT vs BIGINT are unlikely to cause any problems and are

Perhaps Wirth would say that compilers are _close enough_ to user programs to be a decent enough representation in most cases. And of course he was sensible enough to also recognize that there are special cases, like matrix operations, wher

Also almost every smartphone I know of has acceleration sensors and can do Kalman filtering of the GPS position to achieve a much higher accuracy in practical use, even if the individual measurements are only accurate to ~5 meters.

True, but they were just meant as easy examples of non-HFT hedge fund strategies.

There's a wide variety of strategies available. The type you mention of picking up small inefficiencies certainly exists but there are plenty of other strategies that involve having some sort of informational edge. Some hedge fund mana
