This is probably going to be similar to Apple’s find system, which is a low powered Bluetooth based system. Apple Airtags and powered-off phones just broadcast a “I am here” signal once in a while that other devices can receive and report back to Apple.
Having used PHP and Java extensively in my career, it’s always entertaining to read what people think about these languages.
Based on some places I used to work, upper management seemed convinced that the “idea” stage was the hardest and most important part of any project, and that the easy part is planning, gathering requirements, building, testing, changing, and maintaining custom business applications for needlessly complex and ever changing requirements.
Absolutely.
I’ve seen so many projects hindered by bad decisions around performance. Big things like shoehorning yourself into an architecture, language, or particular tool, but even small things like assuming the naive approach is unacceptably slow. If you never actually measure anything though, your assumptions are just assumptions.
What? The GPL would have offered no more protection for this exact scenario than the LGPL (or any other license for that matter).
While so many things are so much better than they used to be in the programming ecosystem, I feel like entry-level GUI programming is so much worse.
This will probably be an unpopular opinion, but Visual Basic (pre .NET) was one of the easiest ways to make a simple, contemporary (for the time) GUI. Drag and drop some elements, modify the UI properties, double click and add code. It made for an excellent introduction to programming because the UI portions were simple and intuitive enough to stay out of the way.
The rest of VB wasn’t great. Weird language/syntax/keywords keywords, closed environment, mediocre tooling. But for building UIs? I haven’t used anything as easy as that and it’s been over 20 years now…
I don’t have any recommendations unfortunately. Almost everything I do is web based or command line. Web UIs aren’t terrible, but there’s a learning curve and lots of limitations. Haven’t found anything for desktop apps I like lately (last one I built was also with tkinter for a small Python project. Bleh.)
Best decision I made was taking an internship. I wasn’t really looking for one, but through some connections, one basically fell in my lap. It was in old tech I messed with in high school, so I was reluctant, but getting real world programming experience was fantastic. The team was great and I helped solve some interesting problems on a small project of theirs. They kept me on as long as they could (>1 year). I think people can be way to idealistic, especially when starting out. Go get a year or two somewhere, anywhere. You’ll have a ton more marketability and control over where you end up with experience and professional references.
Biggest career regret was waiting around afterwards for a time to try to get hired on at that same place. Not a ton of programming jobs locally and I wanted to continue my work there, but the company went through semi-frequent growth/shrink phases, and my team wasn’t able to get me hired in, though they did try for a while. There were plenty of other good things happening in my life during the down-time after this job and before the next, so it’s not really something I regret, but I definitely won’t wait on a company like that again.
As a normal software dev, I wouldn’t want to work in the games industry at all. There’s plenty of interesting and well paying work in this field.
And then I tinker on the side. I don’t think it’s ever been easier to make your own games as a hobby. So many great tools and resources to learn from. PICO8 has been a blast, but going to learn something more capable soon - not sure if that’ll be Godot, Raylib, or LibGDX yet, but I’ll probably but I’ll probably try prototyping some stuff to figure it out.
I noticed you don’t have a build/dependency management tool set up. I find having one makes project setup and producing builds much easier, for myself and others.
If you’re interested, I might be able to add Maven to it and submit a PR. :)
My take on a modern Java solution (parts 1 & 2).

Map numbers = Map.of(
"one", 1,
"two", 2,
"three", 3,
"four", 4,
"five", 5,
"six", 6,
"seven", 7,
"eight", 8,
"nine", 9);
/**

public int getCalibrationValue(String... lines) {

*/
protected String getCalibrationValue(String line) {

findAllNumberStrings(line).stream(),
findAllNumerics(line).stream()
).sorted(Comparator.comparingInt(Match::index))
.toList();
return "" + matches.getFirst().value() + matches.getLast().value();
}
/**

private List findAllNumberStrings(String line) {
return IntStream.range(0, line.length())
.boxed()
.map(i -> findAMatchAtIndex(line, i))
.filter(Optional::isPresent)
.map(Optional::get)
.sorted(Comparator.comparingInt(Match::index))
.toList();
}
private Optional findAMatchAtIndex(String line, int index) {
return numbers.entrySet().stream()

.map(n -> new Match(index, n.getKey(), n.getValue()))
.findAny();
}
/**

public static void main(String[] args) {
System.out.println(new Day1().getCalibrationValue(args));
}
}
Bill is a liability.
Project Panama is aimed at improving the integration with native code. Not sure when it will be “done”, but changes are coming.
Wow, that looks really nice!
I use Lua for PICO-8 stuff and it works well enough, but certain parts are just needlessly clumsy to me.
Looks like TIC-80 supports wren. Might have to give that a try sometime!
I might be wrong, but the 2nd case looks like an anti pattern, the loop switch sequence .
The last case looks the most readable to me. Always start with that unless there’s a clear reason not to (eg inefficient multiple nested loops).
I think that’s a fair argument. PICO-8 definitely could be called a primitive IDE. I think it’s closer to being a primitive game engine with so much of its focus being on graphics and sound tooling.
While you can code simple things within PICO-8, I’ve found that as I’ve built bigger things, I work better in an outside editor, even if it only gets me smaller fonts, splitable windows, vim bindings, limited linting, and somewhat broken code completion.
This isn’t a criticism of PICO-8 as an environment. I think there are a lot of strengths in its simplicity, especially for beginner coders.
I tend to make a distinction between a customizable editor with some support for a language (like vim+plugins) vs a dedicated all-in-one tool that fully understands the language and environment (IDE). PICO-8 is hard to place on that spectrum given it’s an all-in-one tool, but switching to a modified editor gives you more features.
This is a very strange article to me.
Do some tasks run slower today than they did in the past? Sure. Are there some that run slower without a good reason? Sure.
But the whole article just kind of complains. It never acknowledges that many things are better than they used to be. It also just glosses over the complexities and tradeoffs people have to make in the real world.
Like this:
Windows 10 takes 30 minutes to update. What could it possibly be doing for that long? That much time is enough to fully format my SSD drive, download a fresh build and install it like 5 times in a row.
I don’t know what exactly is involved in Windows updates, but it’s likely 1) a lot of data unpacking, 2) a lot of file patching, and 3) done in a way that hopefully won’t bork your system if something goes wrong.
Sure, reinstalling is probably faster, but it’s also simpler. If your doctor told you, “The cancer is likely curable. Here’s the best regimen to get you there over the next year”, it would be insane to say, “A YEAR!? I COULD MAKE A WHOLE NEW HUMAN IN A YEAR!” But I feel like the article is doing exactly that, over and over.
I’m reluctant to call much “bloat”, because even if I don’t use something doesn’t mean it isn’t useful, to other people or future me.
I used to code in vim (plus all sorts of plugins), starting in college where IDEs weren’t particularly encouraged or necessary for small projects. I continued to use this setup professionally because it worked well enough and every IDE I tried for the main language I was using wasn’t great.
However, I eventually found IDEs that worked for the language(s) I needed and I don’t have any interest in going back to a minimalistic (vim or otherwise) setup again. It’s not that the IDE does things that can’t be done with vim generally, but having a tool that understands the code, environment, and provides useful tooling is invaluable to me. I find being able to do things with some automation (like renaming or refactoring) is so much safer, faster, and enjoyable than doing it by hand.
Features I look for/use most often:
Features I don’t use or care so much about? Is there much left?
I do code in non-IDE environments from time to time, but this is almost always because of a lack of tooling than anything else. (Like PICO-8 development)
Oh, nice! I’m going to have to check that out!
