There are many counter-factual hypotheticals like this in common speech.

"if pigs could fly"

"when hell freezes over"

"when Trump and the GOP care about truth"

They all mean the same thing.

Yes. It is hard to this honestly and correctly. That would mean that normal people wouldn't make these cuts.

It also has very little predictive power for the loon with the checkbook right now. He might just as likely notice that people care a lot about that issue and hold it for ransom.

Not with X-rays they aren't.

I can't comment on your detailed knowledge of the state of the art, but your points resonate (particularly because I have tried to generate Julia and Lean code).

So, as with any less informed user reviewing LLM output, what you say definitely sounds plausible and correct.

Percentages don't work like that, either. Since buyers are mostly bound by available monthly budget, raising interest rates increases effective price, which lowers demand at a particular price point which drives total purchase price back down to get the monthly mortgage price closer to affordable.

Obviously, this feedback isn't entirely effective because buyers can simply opt out or delay a purchase but it does have substantial effect.

Thus, increasing interest does not have the full impact as predicted by assuming that purchase price is fixed.

This is really nice work. Of course I, and probably 70% of all HN readers as well, have a bunch of nits to pick (in Java, memory too small, instruction set quibbles and so on) but this is still a very nice piece of work.

One of the best measures of your success is the number of ideas for extension that immediately pop into my mind. Memory mapped I/O of various kinds. DMA controllers with memory mapped registers. A forth interpreter. A tinyGo port. Bigger memory. An emulator for a Raspberry Pi or Pico. A scheme interpreter and compiler. A simple memory management unit.

Ted! We met years ago when you visited Truven for a MapR sale. Really awesome to see you here. :)

Many of the issues you're bringing up popped into my head when I started working with Carson on the project. But they've ended up being not a big deal. The machine is more than powerful enough to get through the lower level CS courses while being simple enough to be blindly obvious about how it all works.

We're also cheating in a few areas like compiling graphics to a separate ROM space to keep the memory usage down.

Carson and I have already chatted about eventually needing an MTMC-32 for Operating System Design classes. That would be the computer where Interrupts, TLBs, cache levels, pipelining, MMIO, block devices, etc, etc, etc would make sense. They'll be able tp build the Operating System themselves and figure out how to make it all work. And ideally share software with each other that they can compiler for their OS. (Like a TinyGo :))

IMHO, this is an important step toward a suite of educational tools for the future.

And so is Python in many ways. The shoe fits.

An oxymoron is a word or phrase that contradicts itself (the word comes from Greek bits meaning "sharp" and "soft"). It doesn't make any sense at all to say that Python is an oxymoron. Python-the-language isn't the kind of thing that can be an oxymoron; "Python"-the-name obviously isn't one because it doesn't have two parts that could contradict one another.

Does your comment mean anything other than "I don't like Python very much", and if so what?

The last sentence was the key:

    And why Python, then? Well, said Sussman, it probably just had a library already implemented for the robotics interface, that was all.

That is the essence of Python's strength ... the eco-system. And the comment about engineering becoming the art of trying to reason about half-documented toys from the huge grab bag of packages is exactly on point relative to the risk and challenge of this transition.

Lack of critical thinking is a key success indicator for propaganda.

Propaganda is less about what it says, but more about how it makes people _feel_.

If you get the feels strong enough, it doesn't matter what you say. The game is over before you start.

The answer depends on the kind of battery chemistry and how literally you mean "rare earth". If you take some slack on the definition and just mean "metal stuff in limited supply", then many battery chemistries have limited supplies.

There are, however, some chemistries with really nice supply chains. The Iron Redox Flow Battery (IRFB) really only needs iron and iron chloride as reactants. Those batteries are being commercialized, but they aren't common (yet?).
