Ah, they "inadvertently ended up deleting the source code". Easy mistake to make. Nothing to worry about then.

So where the article says loading // true setLoading(false) loading // false they mean that it will become false in the next invocation of the render function, I hope?

Refreshing on every click is super fast if you're not loading megabytes of JS. Maybe everyone on HN despises SPAs because we've all seen how fast, light and reliable HN itself is compared to e.g. Twitter where clicking anything us

Yup, the backend IR is shared between JVM, JS (beta) and Native. The new frontend IR, I realize on second thought, will come later[1] with the K2 compiler frontend. The old Kotlin/JS compiler is definitely closer than the new one to wh

Well, yes, but the point was to get a process per request just like PHP, so you'll have to start those processes one way or another. Anyway, it appears uwsgi can be configured to do this, using fork-server[1] and maybe max-requests[2],

To do this in Python, couldn't you just fork the Python process after initializing the web framework etc. and handle the request in the forked process? Optionally keep a pool of pre-forked worker processes so that the request doesn&#x2

The loop can be written using This One Weird Trick that Walruses Hate: for foo in iter(partial(data.get, "foo"), None): handle_foo(foo) So I would only use the walrus operator for the first example (the if statement),

I'm sure you're already aware of this example since it's the canonical one, but to me personally the point is very clear: I use regular expressions all the time and always have to write that little bit of boilerplate, which t

What about setting a simple boolean flag, e.g. setting "cancelled = True" in the UI thread to cancel an operation in a background thread? In Java you would have to worry about safe publication to make the change visible to the o

> V8 is an excellent JS runtime Doesn't Electron use two instances of it though, one for Node.js and one for the browser UI, with some sort of message-passing inbetween? That would tend to slow things down.

The way it's managed in JS, digging the function out of the prototype to apply it, can be done in Python as well. But unlike JS you won't normally have to, thanks to the method not being defined only on one specific type of iterab

It's an unambiguous signal that Mozilla is no longer making software to benefit the user but rather to benefit "trusted partners". That's what's to dislike.

I think the point is that the .NET API for writing a minimal web service is now more minimal, thanks to being designed around lambdas instead of heavy use of OOP. The web server API is just an example of this style of .NET API.
