when I was a kid, my parents taught me that making fun of other people's names, especially surnames, is the lowest form of action.You have my deepest sympathy that your parents hadn't quite evolved to that level of civilisation to teach you the same. Life must be tough for your childhood in such primitive and vile family.

The last thing I want at that time is to have to reason about any of this.I think I’m realizing that what I cherish about the healthcare system up here is not just that I don’t pay bills, but that I don’t even see a bill. Not that the bankruptcy inducing costs aren’t wretched, but I just cannot even imagine being put into a fucked up bureaucratic hell while my family is in a life altering crisis.

Heck, most people would just buy an off the shelf clamshell for that type of product.That doesn't work for the vast majority of products, building a product with 20 COTS parts plus 60 custom tooled parts, and 4 complex PCBAs is

It’s far from a perfect analogy but I would imagine that people were pretty hyped about the novelty of the first legitimately useful compiled programs where they didn’t have to allocate their own registers.

This shouldn't be ignored in the discussion here: The job performed by the humans was broader than what was requested of the model in this benchmark: humans also had to find the relevant invoices (searching through mailboxes, or requesting them from providers) and reason through any circumstances which cannot be inferred from the bank feed and invoices/receipts on their own.

Yeah, hardware is indeed not too hard if you have a trivial hardware project and ignore all the hard stuff.Complexity-wise this is probably the easiest board one could imagine. It's an off-the-shelf MCU module, a 1:1 copy of the MIDI circuit from the specification, and some ports wired straight to the MCU. Throw in a trivial I2C-connected RTC and HSM for good measure. You could probably design this in an afternoon. But indeed: that is a good thing. Not everything has to be complicated, and plent

When John Darnielle from The Mountain Goats started recording albums to cassette on his portable Panasonic stereo, he got a sound that was so much more lo-fi than what could be obtained in a studio, or even with a more expensive recorder and microphone.His genius was to realise he'd made a sound that most professional musicians would never bother with, and thus it became his own and his signature.

Unlike the unit distance problem, the impressive thing here is that it is a proof rather than a counter-example.However, it seems the proof is extremely concise so it seems that it is exploiting a clever trick that somehow all the experts missed.So not to dunk on this amazing result (or move the goal post), but it seems now the only achievement that AI hasn't managed in mathematics is presenting an autonomous "theory-building" proof of an open conjecture.

Zig uses a "single compilation unit" compilation model, so even if we did what you're suggesting, pretty much everything in the post would still be relevant, especially the whole-file stuff and the semantic analysis stuff. Note that there's not really anything special about putting things in separate source files in Zig---files are just a unit of code organization, like namespaces. They don't help the compiler at all (aside from in that very first part of compilation, but that's fast regardless)

Yup. Heating and cooling are 2 things that can be delayed in most cases with little negative effects. A hot water tank set at 60C isn't going to be harmed if it's allowed to cool to 55C due to high power demand it also doesn't instantly empty out with usage.The same is true about climate control. 1 or 2C from the desired temperature is still pretty comfortable but can make a huge difference in power savings, particularly if it's coordinated.That said, I suspect that the even better route for

That "nearly" is doing an awful lot of heavy lifting. It doesn't matter if your AI model is 99% or 99.99% accurate. For a tax return it has to be perfect every time or someone is at best getting a fine or at worst going to prison.Sure, human error happens too, but humans take accountability. That's why accountants are a regulated profession. Until an AI company CEO is willing to go prison if the output of their model is wrong, these tools are worthless.But don't take my word for it, head on over

Hardware has a reputation for being hard for three reasons. First, it scales differently than software. It's far harder to design something you want to make a million of than something you want to make ten of. Second, it's harder to anticipate, test, and correct all the things that can go wrong on the user end. Some people will put batteries the wrong way, some will drop the device on the ground, some will connect it to some vintage equipment you have never seen in your life, etc. And third, the
