Installing PHP 8 on Raspbian is a lot easier when you have a decent guide for it. Found this one tonight:

I finally got my underwater drone back in the water after a long winter hiatus, and I found something neat!

@pollita but no, functions aren't given that level of participation in the ecosystem right now.

@pollita if you could `composer install whoever/println`, then have a `use Whoever\println;` in your file that talks to the console, problem solved.

@pollita I like it! Looks super handy for my typical PHP usage. Of course, your point is also 100% correct (if a bit blunt).

But if we could just make functions "first class" (no pun intended), it wouldn't need to exist at the language level.

Went for a walk today & took a photo of an old rusted car wreck. I'd taken a photo of the same wreck 10 years ago, and thought it would be fun to try again.

@saramg I have it on good authority that Kaos is the enemy of Control.

Aha. I think what I need to do in order to understand all the fiddly draggy and droppy bullshit bits of XCode+Swift ... is version the project in git and look at the damned diffs.

Anything less precise seems utterly inscrutable.

The hull is actually much cleaner than the photo suggests; I think a lot of the speckledness is from light reflecting off the water, amplified by computer-driven postprocessing settings.

Sailboat photo from this weekend:

Not my boat, although it could be for the low, low price of $15,900 CDN.

@saramg ... having enough energy to "do things" is a MYTH. We'll take our black times new roman on white bgcolor, with blue links and purple visited links, and we'll like it.

... well, anyway, I hope your eye is feeling better now.

I want to propose "final abstract class" as a solution to this: it can be extended, and the abstract methods can be added, but nothing more than that can be done. And the extended class has to be final itself.

Is there any way to say in an abstract class that any implementing classes cannot add extra methods, only define the abstract ones?

Not ideal, but I discovered a way around this: reading inbound messages from the API and reacting to them locally. Aka, polling. 🤷 I guess it works, for now.

Maybe there's a way to do this same thing with array_* functions, but nothing came to mind.

I just came up with the most brutal hack to use array_reduce with short functions ... heh.

Since "add to the array" and "return the array" are two operations, I turned them into a single one by using a ternary:

fn ($carry, $item) =>
($carry[$item['category']][] = $item)
? $carry
: $carry,

It eventually came back online; after several further issues with exhausted memory, I finally figured out that `make -j4` was just too taxing for the system (Pi 3 Model B)

Also me: "Now I can't SSH into my Raspberry Pi because, I assume, the CPU melted."
