Running a business means contact with people's opinions. Having your server fall over when you post it to Hacker News means contact with reality.

Oh, I interpreted "a function for exponentiation" as being part of a list of things C uses ^ for. It didn't even occur to me that the sentence had an alternative parsing where it was part of a list of things C uses . C doe

I'm no expert, but this sounds significantly weaker than ZCash at first glance.

This is very insightful. I remember the epoch of clueless startups wasting venture capital on Sun servers. I worked at one of those startups. Warden is clearly correct that if you want to train your AI faster then the optimal amount to sp

I'd be surprised.

No, C does not have an exponentiation operator! Possibly you meant "and not a function for exponentiation". I should have said "followed Fortran rather than BASIC".

I think it's bad to attempt to redefine an established term in this way, but anyway people who use that established definition are not merely fools who lack your wisdom; see https://news.ycombinator.com/item?id=46086919

Those were also US, yes. I don't know why they were so much cheaper. Possibilities include: - Maybe the SEIA is wrong. - Maybe utility-scale projects sign contracts to buy PV modules further in advance. The prices were falling rapidl

Is "just no setuid programs inside them" even an option?

It's just that people are somewhat rational. There are no big wins left in bridge building, so there is no justification for taking big risks. Also, in most software project failures, the only cost is people's time; no animals ar

It's probably true that there are setuid programs that can be exploited if you run them in a user namespace. You probably need to remove setuid (and setgid) as Plan9 did in order to do this.

I read RFC 147 the other day, and it turns out that by "socket" it means "port number", more or less (though maybe they were proposing to also include the host number in the 32-bit "socket", which was quietly d

I forget that people think strings are different from sequences of bytes.

I think Fortran used ** because EBCDIC didn't have ^ or uparrow. ABC and Python followed Fortran rather than C on this point. units(1) supports both.

To be fair, it does link the CVE, so if you don't know what a CVE is, you can click the link. I agree that it's amusing.

It's possible that Roman Catholicism and then the Reformation made sexual repression a part of Western European culture in a way that survived the transition to a more secular society (although the US in particular is still mostly nomi

They surely were not the best use of scarce resources. However, I don't know if you've ever tried to run a business in a poor country. It turns out that the decentralized economic systems they have are also not economically

Yeah, biofuels are laughable, but fully synthetic fuel is a plausible contender, if cheap solar energy lets us make cheap fully synthetic fuel. Your mention of aviation fuel is relevant. That's a context where batteries are not pret

As I understand it, most of the heat that was deposited by radioactive decay in the crust three billion years is still in the crust, not having had time to conduct its way to the surface, and most of heat deposited in the crust even today i

Panels are normally warranted not to drop below 80% of rated output after 25 or 30 years, although some are defective and crack within a year or so. But they don't start dropping off more rapidly at that point; rather, their output de

A heavily used hairdryer is typically in use for 5 minutes per day, so a 1500-watt-peak hairdryer might average 5.2 watts. It needs 1500 watts of batteries (say, 3kWh of 0.5C batteries, or 0.4kWh of 4C batteries), not 1500 watts of solar p

I was surprised at it too, but remember that the US basically doesn't allow Chinese solar panels to be imported.

It shouldn't be, I agree. And eventually it won't be. But SEIA's report https://www.seia.org/research-resources/solar-market-insight... said that, in Q1 of 02024, utility-scale fixed-tilt installations

This project is for district heating, not producing electricity. In general it is true that low-grade heat is difficult to convert to electricity, and there isn't any existing mass-market device that does it. You'll have to make

Pipes are competing with wires, which are much less technically complicated than pipes.
