>though maybe there's a path forward to give a variable a sort of "de-hint" in that in can be everything BUT this type

I think this is called a negation type, and it acts like a logical NOT operator. I'd like it too, and I hear that it works well with union types (logical OR) and intersection types (logical AND) for specifying types precisely in a readable way.

New comment by true_blue in "Dear GitHub: no YAML anchors, please"

the recommendation was what caused the norway problem. it now strongly recommends not to do this, and it says that a Yaml parser should use the core schema unless instructed otherwise. going against the recommendation while saying that you're yaml 1.2 compliant feels like an issue that should be raised with the parser to me. I've never run into this issue in practice though.

is there a parser that says that it's Yaml 1.2 compliant that uses that regex? I don't know of one.

>norway

yaml 1.2 was released in 2009, and it fixed this problem. this is an implementation issue.

I tried the playground and got a strange response. I asked for a regex pattern, and the model gave itself a little game-plan, then it wrote the pattern and started to write tests for it. But it never stopped writing tests. It continued to write tests of increasing size until I guess it reached a context limit and the answer was canceled. Also, for each test it wrote, it added a comment about if the test should pass or fail, but after about the 30th test, it started giving the wrong answer for those too, saying that a test should fail when actually it should pass if the pattern is correct. And after about the 120th test, the tests started to not even make sense anymore. They were just nonsense characters until the answer got cut off.

The pattern it made was also wrong, but I think the first issue is more interesting.

New comment by true_blue in "Pipelining might be my favorite programming language feature"

true_blue — Mon, 21 Apr 2025 17:17:35 +0000

That new Rhombus language that was featured here recently has an interesting feature where you can use `_` in a function call to act as a "placeholder" for an argument. Essentially it's an easy way to partially apply a function. This works very well with piping because it allows you to pipe into any argument of a function (including optional arguments iirc) rather than just the first like many pipe implementations have. It seems really cool!

ublock Origin already has a feature called "strict blocking" which does the same thing. In fact, the placeholder page that this extension takes you to looks almost exactly the same as the one that ublock origin uses.

A project's creator stepping down but having a successor is a strong good sign for the longevity of an open-source project. Whenever I see that transition happen, I think better about the project's long-term future.

the website is just a blank black page for me no matter how long I wait. clearly that's not what it's supposed to be going by the other comments, so that's a bit disappointing.

New comment by true_blue in "Evolving Scala"

true_blue — Wed, 26 Mar 2025 13:50:47 +0000

It takes a lot of humility to admit that the language just isn't as popular as it once was anymore, so kudos for that. The turn towards making the language more approachable to beginners is an interesting one for Scala, and I think it could have a positive impact on the language.

On the few sites I've seen using it so far, it's been a more pleasant (and cuter) experience for me than the captchas I'd probably get otherwise. good work!

>Even the dynamic scripting languages like Python that you'd think it would be easy tended to need an annoying and often 100% boilerplate __init__ function to initialize them.

For this reason, I very much appreciate the dataclass decorator. I notice that I define classes more often since I started using it, so I'm sure that boilerplate is part of the issue.

Well my first thought when I saw it was "oh that's a fun little mascot". From a quick look, it appears to be a hobby project, so I like that it's a little playful. I wish little fun things like this was more common in software, myself.

It's pretty for sure, but it breaks reader view which I use a lot, so I don't like it. also it requires a lot of unnecessary scrolling to read since the text is broken up so much

I think it's clever how the logo is a different shape from Racket's to fit the name of the language, but they kept the same colors and kept the lambda in it.

The reason for the shut down is especially sad. it feels so common that the smaller players are disproportionately hurt by acts like this.

The scariest part for me is that there's essentially no escape from microplastics. If it turns out that they're greatly harmful, what can you really do?

Why do toothbrushes need to be able to make web connections in the first place? I get that it's for tracking brushing habits, but can't that be done with local connectivity only, like LAN or something?

I'm impressed that it's able to understand figurative combinations like this. On the other hand, some of them are confusing:

>Steampunk Pirate Queen + Romance = Steam And Sorcery

What? Is this a reference?
