Hello, all!
What's good
Eggnog and rum is good.
Yes it is
Too bad I'm out of both at the moment...
2:30 AM
Can't drink tonight because GF is at a Christmas party for her work and I need to drive her home.
It's good to plan those things in advance. Good for you!
I'm a (mostly) responsible person lmao
I aspire.
That way she can have fun with her friends, and I don't have to worry about her drinking and driving.
Plus it gives me quiet time at home to work on things that need done.
Which right now is some Android stuff.
Yep, that's the smart way to do it.
I've only done a very little on Android, so I'm not likely to be of much help there, unfortunately.
2:32 AM
And take care of my dog that got bit by the other dog earlier.
Oh, poor doggie!
Nothing too serious, I hope.
It ripped his ear open, so I have to regularly make sure it's still clotting.
Yeah, ear wounds bleed a lot but usually aren't too serious.
True for humans or dogs, actually.
This one ended up being a 1 inch / 2.5cm rip in his ear (all the way through, it's two pieces in that spot now), so it's mostly just lots of blood to clean up every 15-20 minutes or so.
He's a long-haired dog which makes it worse because his hair traps a lot of the blood
And of course he keeps shaking his head back and forth because he's bothered by it being wet from blood, which just makes things worse.
Overall, crap end to the week lmao
I'm just trying to finish up some end of year work, but no actual blood is involved. Yet...

Same here, trying to get my Android brushed up for an interview Thursday...
ah, well good luck with that!
Should go pretty well, it's a Lean / Android coaching gig, so should be fun.
I've found that both from the interviewer and interviewee end, it tends to be that it's clear that it's going to be a fit or not within about the first 20 minutes.
Yeah. Same here. This is an all-day thing because of the type of work.
I'm sure you'll do well.

Hope so.
If not, it be like that sometimes.
Well, I'm off to bed. Full day tomorrow. Good luck to you!

This year is a special one for the Winter Bash tradition.

@SimonForsberg How do you separate data actions from objects in Java? Curious what other folks are doing.
Specifically Android stuff, not that it matters.
@410_Gone Data actions from objects? How do you mean? Example?
What is the problem you are trying to solve?
I have a SQLite DB, and I have a Vehicle class, trying to decide where/how to do the transitions.

What transitions?
You mean modifications to the Vehicle?

8:27 PM
@410_Gone usually you'd want either a "Repository" or a "DAO".
these things are basically the same
The difference between them is where the transaction management is
That's basically what I was thinking, I built a relatively trivial generic DAO.
Yeah I'd go with some repository of some kind
8:46 PM
Are there any alternatives to Function in Java?
(That is, something that lets me pass a function as a parameter.)
@410_Gone Functional interfaces. Depends on what the function you want to pass has as parameters.
not really, no
There's not "one interface to rule them all"
if you have the thing as a method, you can pass it as a "Method reference", though
8:47 PM
There's interfaces such as Function<A, B>, Supplier<A>, Predicate<A> etc
Yeah, method reference might be what you want. What's the problem exactly?
this::someMethod refers to the method "someMethod" on the object "this"
I need a function that lets me pass a table definition, then a decoder for an object.
Two parameters and one output? BiFunction
I.e. database.loadAll<Vehicle>(db, "Vehicles", Vehicle::fromSql)
Or just make your own functional interface.
Where Vehicle::fromSql is Vehicle fromSql(Cursor c).
8:54 PM
ohhh manual mapping
that's a Function<Cursor, T>
But I need Android API 24 at a minimum, which is unacceptable.

welcome to the world of pain that is android dev
