By your incredible criteria of things being mutable strings if they behave nothing like strings but can produce one, JavaScript absolutely does have a mutable string, it’s called Array. It’s also a mutable integer.

FWIW POSIX requires that rename(2) be atomic, it's not just ext4, any POSIX FS should work that way. However this still requires a lockfile because while rename(2) is an atomic store it's not a full CAS, so you can have two proces

Checked the rust version, it has a toctou error right at the start, which likely would not happen in a non-cgi system because you’d do your db setup on load and only then would accept requests. I assume the others are similar. This neatly d

It does not really matter in rust anyway: literals are &’static str so naturally immutable and essentially free, and mutable strings require jumping hoops to share, so it’s hard to unwittingly have one mutate from under you.

The way it works in Python is that string literals are stored in a constant slot of their parent object, so at runtime the VM just returns the value at that index. Though since Ruby already has symbols which act as immutable interned string

Scheduling is the OS’s decision not the CPU’s. Although Intel’s configurations are unhelpful to say the least: it’s hard to make good scheduling decisions when Intel sells a 2P, 8E, 2LE as a 12 cores to the user.

Which is exactly what is happening. It makes sense for cars as well, as they need to top up more frequently highway carge stations become a regular service rather than an overpriced emergency one.

According to the electric trucker channel there are rumblings about altering the last clause, because currently if you end your day at a charging station you can’t free it up and go to a regular parking space when you’re topped up.

It is a pretty limited achievement as-is: ignoring maglevs, a tgv test train reached 575 kph back in 2007, and China had test trains reaching 487 in 2011. China’s next-gen is being deployed with goals of a 400kph service speed.

That… has nothing to do with xpath? If your document has namespaces, xpath has to reflect that. You can either tank it or explicitly ignore namespaces by foregoing the shorthands and checking `local-name()`.
