I don't love Python's async API either, but I think a lot of its complained-about complexity arises from two things: making "when does the coroutine start running" a very explicit point in code (hence the Task/await

Correct, sorry! My phrasing was off-the-cuff and less than precise. File descriptor = reference/pointer-ish thing. File description = referenced data. close(2) = decrement refcount to description by closing descriptor; actual destructi

You joke, but there are programs that do exactly this.

Not only is dlclose(3) not guaranteed to close/unload the library, close(2) isn't guaranteed to close a file! . If the same file descriptor is open in another process (e.g. one that has it via fork(2) FD sharing either without ch

I’m with the sibling commenter: Python’s heavy-weight-ness and overhead is a thing, yes, but it’s not the same kind of overhead that gets us to power hungry bloated systems—that stuff has more to do with (on the server) wakeups, memory thra

Okay, but . . . how would that work? A syscall gives back a pointer (I thought the point was to avoid syscalls/context switches)? An io_malloc userspace function (great, now how do I manage lifetimes of the buffers it hands out)? Somet

Looks interesting; does it take a different architectural approach than WarpStream did? That’s not coded “you’re reinventing the wheel”; WarpStream had some significant drawbacks, so I’m truly curious about different approaches in the messa

It would, hence why major cloud providers currently disable io_uring in many of their compute environments.

Eh, not really. Async (in this semantic context) is generally about cooperative concurrency and also often about concurrent or multiplexed I/O . Pthreads aren't async by those definitions, though you can run async code within a

I think it's not quite that bad (and I know that this has been litigated to death all over the programmer internet). If you are forking from a language/ecosystem that is extremely thread-friendly, (e.g. Go, Java, Erlang) fork is m

Let's say a function "foo" calls "fn bar(_: &mut T) -> ()". When passing a mutable reference, the lifetime of the object is largely decided by "foo" (with some caveats). Now, let's say that &qu

I was also onboard with GP’s comment until I got to this part. Audit data in the same DB is great, because it can be written transactionally for relatively cheap (multi table updates, triggers, actual transactions with multiple writes, etc)

I’m generally pro SQL-as-interface, but this is just wrong. Not only are there all sorts of bizarre constraints imposed by databases on migration behavior that application code can’t express (for example, how can I implement a transaction-

This feels like neglected software to me. It has a strong odor of a product that the owning team does not consider a major priority and takes an ‘is it working well enough?’ approach to issues rather than an ‘is it working well ?’ approach

I expanded on this in an adjacent comment: smartcards might be a cheap and easy solve here. Insert the card to log in, pull the card and you get logged out. Bonus points if the smartcard is also your access card for e.g. the break room.
