That's still event handling. You can do basic binding between outputs and values, but more macroscopic changes (closing a dialog, changing tabs, etc) requires tracking the state your UI is in, and manually transitioning. This is marked

React isn't really anything like 90s UI libraries. It is, however, very much like the fairly recent native immediate-mode GUIs that have come out ( https://github.com/ocornut/imgui , https://github.com&#x

With even a tiny bit of CSS (which can be inlined in the head tag if you don't want an extra fetch), you end up with this: https://jmn.link/css-example.jpg . That's 152 bytes of non-minified CSS to accomplish that

JIT compilation makes decisions on how to optimize the generated code based on run-time analysis the program. AOT compilation doesn't have access to that information, which can lead to slower code. However, because AOT compilation isn&

There are several implementations of Common Lisp that are still being actively developed. Because Common Lisp is so easily extended, the ossification of the standard is actually a good thing. The stability of the standard means that code wr

I use the Overtype extension for that: https://marketplace.visualstudio.com/items?itemName=adammara... It hasn't been updated in over a year, but I've yet to have any issues with it.

Scala 3 will still be able to use Scala 2 libraries, so it won't be quite as bad.

Modern C compilers do some very tricky things with undefined behavior. See https://blogs.msdn.microsoft.com/oldnewthing/20140627-00/?p=... for a very detailed example. See https://blog.regehr.org/a

It won't. If any of the functions on the right-hand side of the '<-' return Nothing, then the later lines do nothing. Think of the '<-' operator as a 'flatMap' call for Optionals in Java, if you are

A woman does not equal a man, and she shouldn't. Careful with your wording here. I'm assuming you meant 'is not the same as'; however 'does not equal' could easily be interpreted as 'not the equal

I don't use Node, but my understanding is as follows: Rather than blocking the thread on IO, you instead arrange for a callback to be executed once your IO operation is completed. The thread is then free to work on other tasks (e.g. ot

I suspect the sparse encoding was used so that punched cards were stiff enough to survive being fed through a reader. (related: https://en.wikipedia.org/wiki/Lace_card )

In many cases the function passed in will not make any sense outside of the context in which it is used. For example, consider: const kittenNames = cats.flatMap(cat => cat.kittens) .map(kitten => kitten.n

You might be confusing the associative property with the commutative property (I do this all the time): associative: (a + b) + c = a + (b + c) commutative: a + b = b + a For example, appending strings is associative, but not commutative. Ap

That's fascinating; thank you for that. I often find academic papers are too densely written to me to read, but the authors of that paper have gone out of their way to describe everything in a straightforward manner.

Deterministically locating all undefined behavior is undecidable. Static analyzers can only locate a subset of it. Commonly-used type punning techniques frequently exhibit undefined behavior due to strict aliasing: https://blog.r

There's a lot more to data structures and algorithms than sorting. For example, just knowing that bloom filters or interval trees exist opens up a ton of options, even if you don't implement them yourself. For that matter, the cho

Linus directly contradicts you in that linked thread, for this specific situation: And as mentioned, there _are_ exceptions. Some types just get _sooo_ complex that it's inconvenient to type them out, even if they are perfectly

That's fantastic news! I currently use Scala for most of my personal development, but having type classes would make F# attractive enough for me to switch over. I much prefer the cleaner syntax of F#. Losing HKT would be a shame, but t

You only have to learn what '?' does once. You have to write (and more importantly, read) the Go boilerplate every time.
