I don't think the order creates any new violations of privacy law. OpenAI's ability to retain the data and give it to third parties would have been the violation in the first place.

I was a TA for an intro to assembly language course, which means I got my office hours full of all of the students who struggled with assembly language and had to work with them one-on-one to get them over their roadblocks to pass the class

The primitives of control flow in programming languages are sequencing, if, while, for, switch, return, and "early return" (goto restricted to exit a containing block). We might compile these into a form that represents everything

The first one doesn't seem to actually give me the script, so I can't test it. The second one didn't work for me without some code modification (specifically, the "count code blocks" didn't work), but the resul

Most of my day job is worrying about the correctness of compiler optimizations. LLMs frequently can't even accurately summarize the language manual (especially on the level of detail I need).

There is no solution, much less one that is portable across different Unixen. The core problem is that, because of the ability of filesystems to effectively contain other filesystems within them, the number of bits to uniquely identify a fi

To get the right answers for accounting, all you have to do is pay attention to how you're doing rounding, which is no harder for floating-point than it is for fixed-point. Actually, it might be slightly easier for floating-point, sinc

by jcranmer 1y ago
For starters, it's giving up a lot of performance, since fixed-point isn't accelerated by hardware like floating-point is.

I've found fear of the use of floating-point in finance to be a good litmus test for how knowledgeable people are about floating-point. Because as far as I can tell, finance people almost exclusively uses (binary) floating-point [1], w

Floating-point is completely commutative (ignoring NaN payloads). It's the associativity law that it fails to uphold.

A double-precision float has ~16 decimal digits of precision. Which means as long as your bank account is less than a quadrillion dollars, it can accurately store the balance to the nearest cent.

Pointer provenance is UB in the C/C++ sense, although it's one that largely lurks in the implementation-defined behavior of "integer/pointer casts are implementation-defined." The closest you're going to find

Plenty of things! The resulting pointer may not be pointing to an object that is currently live, for example. It may not even be pointing to an object that makes any sense in the language's object model. It might be pointing to a retur

How would you implement integer-to-pointer conversions without UB?

This is already discussed for Rust: https://github.com/rust-lang/rfcs/pull/3605 . TL;DR: it's not as easy as it looks to just add "freeze."

Gauge differences less than ~25mm are considered interoperable to some degree. At a 4mm gauge difference, that's basically less than the tolerance for even the most demanding high-speed track.

I don't think it's so much AI that is screwing up the education system as it is the "STEM über alles" crowd doing so. They've spent decades effectively telling people that it's the STEM fields that matter most,
