In general, most compilers are generally single-threaded for most of the compilation process--at the very least, compiling a single file (translation unit) is almost always done using just one thread. However, nondeterminism does creep in i

Compilers are multimillion line programs, and they have an error rate which is commensurate with multimillion line programs. That said, I think like half the bugs I see get filed against the compiler aren't actually compiler bugs but e

Something like half of all rigid airships ended their lives in crashes. That's an airframe loss rate far in excess of anything you see with regular aircraft.

From the reporting I've seen, they're not firing "at random", they're firing more or less every single new hire they can, because new hires have less protections than more established employees.

Instead of trying to put words in my mouth, let me just say what I think: I believe software patents are no more legal in the US than they are in the EU, and this is based on SCOTUS precedent in the US that makes the legal argument for soft

My suspicion is that software is no less patentable in France (or the EU as a whole) than it is in the US. Which is to say, throw in a generic processor and it's kosher enough to get granted. (Even in the US, Alice says that "do i

The way I interpret it, if you don't have a dedicated exclusive access to a parking space, you don't really have at-home charging, because the exclusive access is what gets rid of the need to negotiate with other people for access

There are over 300 French patents in the H.264 license pool, and the very first one looks like a software patent to me, and I suspect most of the rest are the software patents that you confidently claim don't exist.

Rust does help to prevent memory leaks, but it is not considered a soundness bug to leak memory, whereas it is a soundness bug to (e.g.) use memory after it is freed. Historically, what happened in Rust is that shortly before 1.0 was releas

Using different enums doesn't help, because C will happily let you cast enum A to enum B implicity. In Rust, I can express an API which can't be used incorrectly. In C, I can't . Sometimes, in C, you can sometimes get to
