As Playboy did not choose to defend the copyright, it is essentially public domain.

Nope. Unlike a trademark, there is no obligation to defend copyrights to preserve them. It's up to the owner to decide whether or not to sue for infringement.

So, how does the cost and yield of this method compare with traditional methods of converting CO2 and sunlight into useful fuels? E.g. a field of grass or forrest of trees?

"When is it time to start shorting Apple?"

About three months ago, when AAPL was around 200$ per share.

Indeed, it's also a breach of Apple's conditions for the use of its iCloud services (section IV.A) and therefore could presumably result in termination of the account.

Interesting. I wonder what the citizenship requirements for Nauaru are? Just asking for a friend...

Unlocking a USB may not be taxable but disposing of the bitcoins will be a taxable capital gain event in many countries, e.g. https://www.irs.gov/businesses...

I couldn't care less about Teams memory footprint and CPU time consumption. What I want its the wallclock consumption halved.

Ah, Microsoft... Who else would decide that what a file-sync service that chokes on files with a '?' in their name really needs is a reincarnated Clippy?

Carl Sagan's adage that "extraordinary claims require extraordinary evidence" is not a "logical fallacy". It is better thought of as a statement about (Bayesian) inference.

For example, supposing that I have an a priori belief that the probability of life on Mars is one in a million. Loeb finds a rock that he claims has a 99% chance of being made by a Martian and and a 1% chance of being made here on Earth. I would update my belief to one in ten thousand, which is still a long way from being persuaded.

A better example of a logical fallacy is 'They don't seek the evidence and they argue, "Well, we don't have any evidence...."', which misrepresents his opponent's position and is a example of the straw man fallacy.

CBC: How much?

A system to exploit the effect needs to sustain an electrochemical potential difference to drive the flow of molecules through the holes. This electrochemical potential difference might be generated by a temperature / pressure / density gradient but maintaining it as the molecules pass through the membrane takes heat or work. This will equal or exceed the electrical power that can be extracted (i.e. the emf generated by the device multiplies by rate of charge separation.) In short, if you invent a perpetual motion machine it isn't going to work in practice.

Shouldn't use light switches to control motors. Could well be why it failed so quickly.

In the UK, publishing disclaimers with material that is defamatory can increase damages. The inference drawn is that the publisher knew or had reason to suspect the material was false but recklessly published it anyway.

There was radio interview with Asimov, broadcast in the late 70's IIRC, in which he said that the loop-holes in The Three Laws were deliberate and necessary because it was these that allowed him to write interesting stories.

The examples from ChatGPT I've seen contain poor science written written about in good English. Scientific papers written by humans typically have good science written about in poor english. It's not difficult to tell the difference if you know anything about the field that's being written about.
