The real answer IMO is how they (don't) integrate with generics, first-class functions, and the type system in general. If you try using a checked function inside a stream() call you'll know exactly what I mean. Yes, it's tec

But then what name would they use for tuples, which are distinct from records?

You forgot to test for associativity: ((1-1)-1) vs (1-(1-1)). Your implementation does handle it correctly though, but it requires some care when using parser generators :)

I've never experienced this. Have you tried disabling all your extensions to see if one of them is causing it?

Installing it is easy, what's harder is making sure all your collaborators have the same packages and versions of everything.

I don't think anyone had tried copying it until after I figured out the problem, the bug report would've just been a screenshot.

Here's a fun one that's not really code-related: I was working on a web application with a maintenance mode feature where it would show a "system offline" while changes were rolled out etc. We noticed there was a typo (o

Well somebody had better discard it now, lest it start existing at some point in the future.

I was with you until the second sentence - there's so many better syntaxes C could've used but that's not one of them.

One of my personal projects uses a similar idea, but it's a word game (scrabble-like) and it's hosted statically: https://jcparkyn.github.io/scrobburl/ Repo: https://github.com/Jcparkyn/s

What kind of deprecation are you talking about? Assuming deprecated functions/types/etc, isn't this something your compiler or linter should catch?

I think an important difference is that when you shuffle them, the unfairness stops being correlated across multiple assignments, so the "aggregate" unfairness over the course of the semester is much lower.

One feature I've never seen in test frameworks that I think would be good: Instead of concurrency being a boolean on/off, tests should be able to declare a list of shared dependencies (e.g. using arbitrary string identifiers). The

Your first example should be more like return source(criteria).results In your SQL, `results` isn't the variable you're assigning to, it's the column you're reading from source.

- The comment is referring to a graph that used 10^6 on the vertical axis, which is a very common way to format graphs with large numbers (not just "lately"). It's also the default for a lot of plotting libraries. - 10^n is m

(Not saying anything in your comment is wrong, just an additional data point) For "big tech" in Australia, ~$160k is pretty much the starting compensation for graduate/entry level SWEs.

Another option would be to replace the X with a small (i) symbol or similar, so at least users won't be confused when it doesn't do what they expected.

Is there any evidence of him actually following up on any of those pledges? The example from the article about his "billion dollar" donation (of which only $4MM seemed to have actually been spent) makes me skeptical. Edit: It appe

Interesting example that I hadn't considered. But, since Typst is a programming language, there are lots of ways the same thing could be achieved directly in the language. E.g.: // Change this to switch languages #l

Looks cool (I'm a big fan of Typst), but I do question the value of moving the data to yaml, rather than just building a set of Typst functions and styles (see example below). To me, it's one of those things people often do becaus

I know you were mostly joking, but for cloning dates you can "just" use the constructor ( https://stackoverflow.com/a/69601256 ).
