for arbitrary complex values sqrt() gives 2 answers with +- signs

so sqrt(square(-i)) = +-i, one of which is x

Armisael16 · a day ago

The sqrt function returns the principle square root, not both. That’s true for all numbers, positive, negative, and complex alike.

What's crazy is that productivity per employee just keeps increasing year after year, but successive neoliberal governments continue to lower corporate taxes. They should be doing the exact opposite! Taxes should be raised as productivity increases! AI is just one more tool that gradually increases productivity, among others.

Armisael16 · 3 months ago

Why should productivity and corporate tax rates be correlated at all, up or down? The link there is not obvious.

that's fair, I was kinda just inferring as someone whose space travel experience is limited to Kerbal Space Program. The point still stands though: whether it's atmo or gravity the moon has a lot less of it than the earth, but still has a lot more local resources and space to put things semi-permanently. Long distance slower than light space travel has a Sahara problem and at least in the solar system the same sol'n could be used: leapfrogging from cache to cache. The ISS is a better cache than the nothing that was there before it, but a functioning moon base would be an amazing cache from which to launch ops into the deep solar system.

If you’ve played KSP you should know how totally useless Mun bases are.

ZIRP is an American thing? In that case maybe we could try comparisons with the job markets in other developed Western countries that didn't have this policy. If it was because of ZIRP, then their job markets should show clearly different patterns.

Armisael16 · 10 months ago

There isn’t anything magically about precisely zero percent interest rates; the behavior we see is mostly a smooth extension of slightly higher rates, which the EU was at.

And of course ZIRP was pioneered in Japan, not the US.

We need to solve the problem where the system breaks when there are more than two parties: the "spoiler vote".[1] It is the single largest problem facing American democracy. Dump the electoral college system and start from scratch. Look to real democracies like Europe where they use ranked choice voting - also called instant runoff voting.[2]

IRV is also vulnerable to third-party spoilers; the squeezed middle is a well-known phenomenon in that system.

Is it just a “minor” correction and what does that even mean? The market closed around 6% down from what it was just 5 days ago, and 8% down from a few weeks ago. Volatility was incredibly high yesterday, even higher than the last big peak, which was at the start of the pandemic. There has been low predictability in how the fed will act and lots of debate about whether they are too late on acting. This has nothing to do with Japan, and everything to do with the US jobs report, which is literally what triggered the sell off. I am not sure why this blog post is trying to create a link to Japan.

Let’s also not forget, that the economy’s growth depends significantly on a few mega corps, which is not healthy. And those companies are likely overvalued. Berkshire Hathaway dumped Apple shares, Amazon lowered its guidance, and Nvidia - and AI as a whole - is now clearly known to be overhyped. If you remove these companies, what do you have? A stagnant economy with inflation that isn’t under control, reduced employment, and ballooning public debt. Clearly this isn’t a good situation, but America is lucky to have a strong currency and low exposure to global unrest.

I think your latter point that half the population wants the economy to crash for political gain is potentially true but it is equally true that the other half wants to pretend the country is doing well in every single way so Harris will have another talking point. So I am not sure why it is relevant.

Armisael16 · 2 years ago

The standard definition of a correction is a 10-20% market decline. “Minor” corrections aren’t defined, though one could imagine an event that barely meets the threshold making sense.

But yes, strictly you are right - this isn’t a correction at all.

Suspect we need more efficient cooling so things like heat pumps that can run in reverse and actually cool the building fabric down

Armisael16 · 2 years ago

Cooling is the main and normal direction heat pumps run in; heating is the new and unusual way to use them.

>You could fit Europe inside the US.

If we're considering contiguous US, then no.

Europe is 3.93 million square miles.

Contiguous US is 3.15 million square miles.

Armisael16 · 2 years ago

Why would you ignore the largest state in that land area calculation? Alaska still isn’t quite enough to push the US up, but it’s good for another 20%-ish increase in land area over the contiguous number.

True - at least most "737-only" low-cost airlines (Southwest, Ryanair, ...) use the older 737 models and the MAX (which Ryanair has rechristened to "737-8200" because of... reasons) interchangeably AFAIK.

Armisael16 · 2 years ago

Southwest has dozens of Max 8s, for what it’s worth: https://www.planespotters.net/airline/Southwest-Airlines

I booked a flight with them last night, and it’s scheduled to fly on one.
