That's my recollection, too--IQ was developed to judge kids' "mental age" (how far ahead or behind they are compared to their peers in their current grade) and was only later retrofitted onto the g factor model of intell

The differences are almost certainly not in how the two OSes rounded floats--the IEEE rounding modes are standard, and almost no one actually bothers to even change the rounding mode from the default. For cross-OS issues, the most likely cu

I think you're misunderstanding pointer provenance, and you're being angry at a model that doesn't exist. The failure mode of pointer provenance is converting an integer to a pointer to an object that was never converted to a

Give me an example of a program that violates pointer provenance (and only pointer provenance) that you think should be allowed under a reasonable programming model.

by jcranmer 1y ago
In a compiler, you essentially need the ability to trace all the uses of an address, at least in the easy cases. Converting a pointer to an integer (or vice versa) isn't really a deal-breaker; it's essentially the same thing as pa

Pointer provenance probably dates back to the 70s, although not under that name. The essential idea of pointer provenance is that it is somehow possible to enumerate all of the uses of a memory location (in a potentially very limited scope)

The role of the atomic bombings in compelling Japanese surrender is still hotly debated, and will remain so until the end of time because, quite frankly, we don't have the historical record that will conclusively decide the debate. Str

One of the most amusing things to me is the amount of AI testimonials that basically go "once I help the AI over the things I know that it struggles with, when it gets to the things I don't know, wow, it's amazing at how much

You've messed up the direction here. Reducing unknown-complexity to NP-complete means you can bound the complexity by above, but not by below. I can reduce binary integer addition to SAT, which means that binary integer addition is no

To be fair, it did scream before it imploded. They just disregarded the screams because they couldn't afford to make sure it was still working.

The chief reason software fails is because programmers are insufficiently aware of all of the reasons the software can fail. Sure you need a test to make sure that you handle the error correctly, but if the function signature doesn't i

The express purpose of building Servo in the first place was to experiment with ways to parallelize the layout algorithm. The advantage of Rust is that it is a language which enables the compiler to better enforce some of the rules that nee
