Yep, some code examples from the official documentation. This:

printPersons(
    roster,
    (Person p) -> p.getGender() == Person.Sex.MALE
        && p.getAge() >= 18
        && p.getAge() <= 25
);

…is syntactic sugar for this:

interface CheckPerson {
    boolean test(Person p);
}

printPersons(
    roster,
    new CheckPerson() {
        public boolean test(Person p) {
            return p.getGender() == Person.Sex.MALE
                && p.getAge() >= 18
                && p.getAge() <= 25;
        }
    }
);

…which is syntactic sugar for this:

interface CheckPerson {
    boolean test(Person p);
}

class CheckPersonEligibleForSelectiveService implements CheckPerson {
    public boolean test(Person p) {
        return p.gender == Person.Sex.MALE &&
            p.getAge() >= 18 &&
            p.getAge() <= 25;
    }
}

printPersons(roster, new CheckPersonEligibleForSelectiveService());

The printPersons function looks like this:

public static void printPersons(List<Person> roster, CheckPerson tester) {
    for (Person p : roster) {
        if (tester.test(p)) {
            p.printPerson();
        }
    }
}

Basically, if you accept a parameter that implements an interface with only one method (CheckPerson), then your caller can provide you an object like that by using the lambda syntax from the first example.

They had to retrofit lambdas into the language, and they sure chose the one hammer that the language has.

I always hated the implementation for .toString() of Duration. It gives you a string like that: PT8H6M12.345S (not a hash)

Apparently, it’s an ISO 8601 thing, but what the hell am I supposed to do with that?
It’s not useful for outputting to end users (which is fair enough), but I don’t even want to write that into a log message.
I got so used to this just being garbage that I would automatically call .toMillis() and write “ms” after it.

Well, and not to gush about Rust too much, but I recently learned that its debug string representation is actually really good. As in, it’s better than my Java workaround, because it’ll even do things like printing 1000ms as 1s.
And that’s just like, oh right, libraries can actually provide a better implementation than what I’ll slap down offhandedly.

It makes it look like they’re just adding random noise to avoid colliding with existing syntax. Maybe they can try a UUID next time…

Yeah, I came to Rust from Scala and Kotlin, where equality is default-implemented (for case class and data class respectively, which is basically all we ever used), so this meme surprised me a bit.

I do actually like that you can decide a type cannot be compared, because sometimes it really just doesn’t make sense. How would you compare two HTTP clients, for example? But yeah, it certainly is a choice one can disagree with.

I find these videos give a very visual explanation and help to put you into the right mindset: http://intorust.com/
(You can skip the first two videos.)

Sort of when it clicked for me, was when I realized that your code needs to be a tree of function calls.
I mean, that’s what all code is anyways, with a main-function at the top calling other functions which call other functions. But OOP adds a layer to that, i.e. objects, and encourages to do all function calls between objects. You don’t want to do that in Rust. You kind of have to write simpler code for it to fall into place.

To make it a bit more concrete:
You will have functions which hold ownership over some data, typically because they instantiated a struct. These sit at the root of a sub-tree, where you pass access to this data down into further functions by borrowing it to them.

You don’t typically want to pass ownership all over the place, nor do you typically want to borrow (or pass references) to functions which are not part of this sub-tree.
Of course, there’s situations where this isn’t easily possible, e.g. when having two independent threads talking to each other, and then you do need Rc or Arc, but yeah, the vast majority of programming problems can be solved with trees of function calls.

The first iteration of the Rust compiler was written in OCaml…

It’s like back in the 80s, when games had amazing hand-drawn covers and then the graphics was just text or simple shapes, but now with gameplay.

Hmm, I don’t know anything about Whoogle, but from other privacy-conscious search engines, I would expect it to work when you use that URL in your bookmark.

Three things I can imagine:

• Something in your hosting stack strips the URL parameters, like maybe your reverse proxy, if you use one. You might be able to see in the Whoogle or web server logs, which URLs actually reach it. Might need to set it to debug/trace logging.
• Maybe there’s a flag in the Whoogle configuration you need to enable to accept these preference URLs.
• It’s a bug in that Whoogle version.

You don’t want to use exceptions in normal control flow, because they’re extremely slow. Every time you throw an exception, it has to collect a stacktrace, which is hundreds, if not thousands, of calculations, compared to a handful of calculations for returning a boolean or an enum variant.

Interesting. I almost guessed that variant, too, but figured it would be a bit too wild for a country to auto-adopt most laws that another country implements. 🙃

I stopped using Reddit a few years before the whole stupidity, because the culture was fucking with my head.

Then I did the Mastodons for two years or so, with Lemmy eventually entering the mix. And then as Lemmy got more users and content, it took over as my preferred platform.

I’m more surprised that it even got offered there. There’s some legal hurdles to clear for selling in a new country, and I guess, one of their distribution platforms decided it was worth it.

I guess, the Vatican might not have a ton of laws, though…

Codeberg also does have Pages.

Still uses Git, but yeah.

Codeberg recently held a translation event where projects could sign up, if they wanted help. You can still look at their resources here, or I guess, you can just pick out a project and start translating over here: https://translate.codeberg.org/

Depending on your file manager, you may be able to hold Shift while triggering the delete to get a hard delete.

Shift+Del is pretty much standardized as the keyboard shortcut. And here on KDE, I can hold Shift while clicking the “Move to Trash” menu entry, too (well, it actually replaces the menu entry with one for permanent deletion, but that’s effectively the same).

I, unfortunately, have to use GitHub at $DAYJOB and this is me. I navigate most of the webpage via the URL bar now.

Basically, let’s say I’m working on a repo github.com/tomato/sauce/ and want to navigate to the Releases page.

Via the webpage:

1. Type github.com into the URL bar.
2. Don’t find tomato/sauce/ in the list of recent repos, even though it’s the only repo I work on.
3. Click on some other repo that’s at least in the tomato/ org.
4. Navigate up to the tomato/ org.
5. Find the sauce/ repo in the list.
6. Traverse half the fucking screen to hit the “Releases” heading in the middle of the About-section.

Via the Firefox URL bar:

1. Type gi→t→s→r→.
2. Hit Enter.

I admit, it’s hard to compete with the latter, but I wouldn’t know how to navigate that way, if the former wasn’t so terrible.

I mean, when you hold down the Alt key, it’s convention that GUI toolkits underline a letter in the text of UI elements, and when you then press Alt + that letter, it’ll activate that UI element.
That way, you can navigate most apps in a keyboard-driven fashion, although it is certainly not the most comfortable to use…

It’s this one: https://codeberg.org/trem/jot/

Not a fan of it using Electron and a proprietary license.

But I also actually like this workflow. Being able to note things in my regular text editor with the keybindings I know, is quite important to me.
Well, and an even more personal preference, but my way of using a desktop OS involves a lot of workspaces, so the global shortcut to summon a new editor window on the current workspace actually gets a lot of use.

You can probably just do sleep 5 && grim as the program to run.

It depends on your desktop environment or window manager, how you’d bind a command to a keybind.
