Move fast and break things does not describe Java well at all. Their process is still very deliberate, they go to some lengths to avoid getting it wrong when they add new features to the standard. New features have to get through their p

It's a non-moving collector. It might be high performance by the standards of C++ garbage collectors, but I doubt its performance could be anywhere near what a decent JVM can manage, especially in the absence of finalizers/destruc

No, it's as I said. There was a famous case in 2017 where a surgeon was violently removed from an overbooked United Express airliner. He had refused to leave voluntarily, as doing so would have meant not seeing his patients the next da

It's not uncommon to travel for medical care, or for medics to travel for work.

Of course Bernstein isn't about to file lawsuits against his users, given his motives, but (prior to the public domain dedication) he might have stood a chance in court if people were downloading and using his copyrighted software with

> entrenching a preference for one style of licensing over another. Sure, that's true. The intent of the law is to give a special carve-out for, in essence, Free and Open Source software. It seems clear that it was deliberately writ

Sure, but of minimal practical impact. The Free and Open Source community has long discouraged releasing software into the public domain, as it has clear drawbacks compared to just using a permissive licence. The legal intricacies of the pu

If it's possible for program execution with some particular input to lead to a divide-by-zero, that's a bug, especially if the program is expected to be able to handle malformed inputs, or perhaps even deliberately malicious ones.

For a project like Postgres could it make sense to use a JIT with no use of SSA form?

There's more to it than that though. Defects in JIT logic can lead to nasty low-level bugs. Plain old interpreters, especially if written in a safe language, are unlikely to have similar issues. This is important when the input code is

Interesting, thanks for the link. LLVM isn't the only game in town though, nobody using it (or libgccjit) for JIT should be surprised to see relatively long compile times. I wonder if the postgres project will try a different backend.

Thanks, sljit looks somewhat similar to GNU lightning. On reflection I wonder if I overstated the widespread use of JIT and of JIT compiler frameworks. All the 'major' well-resourced high-profile JIT-based interpreters I can think

Do you have a source for raw surveillance footage not being subject to copyright? I'd not heard of this, and a web search didn't turn up anything.

For what it's worth Ada currently has RFCs for constructors in destructors closer to the C++ way. They're currently supported in the GNAT (GCC Ada) compiler. https://github.com/AdaCore/ada-spark-rfcs/blob

Agreed. The quality of a software package doesn't change when its last user stops using it. We don't say that the Apollo Guidance Computer software is of low quality these days given that nobody's using it. Software quality i

I'm not sure about that definition. If your software solves a problem that many users face, that makes it useful and, presumably, valuable, but it doesn't mean it's of higher quality than niche software of relatively little u

> I think a "resilience to hardships" would be a better definition of quality Does this refer only to program behaviour? I figure readability should count toward quality, but it doesn't directly affect program behaviour.
