I like the idea that some stoner somewhere has an inventory full of red mushrooms and no idea why

Meanwhile, some sleazy guy keeps getting banana saplings and is trying to figure out what that even means.

To be fair, the saplings are nice.

While I can't speak for everyone, I personally am quite enamored of the EXUBERANT COWBOY.

EXUBERANT COWBOY sounds like a firmware exploit codename

So our software creates charts. Data requests are asynchronous and they return data with metadata to which chart they belong to. If data requests fail, they return no data, only an exception.

So I am now coding a system to run a Service, which runs a Task of periodically checking a list of pending chart requests. If a chart is not generated after n seconds, the task assumes the data requests failed and we did not get the data to create the chart.

It compares timestamps of now and the moment a chart creation request was issued, so it can understand how “old” each chartgen request is.

I asked that would it be possible for the datamanager to return some kind of useful metadata, even within the exception? I was shot down so I am now coding this stupid rear end garbage collection service.

I guess that after enough cases like this it is how spaghetti monster and coding horrors are eventually born..

... Can you not just see that an exception was returned, instead of polling?

Thanks! The best part of the thread is definitely well after the initial post. It's worth reading the whole thing.

"Don't let anything access production except production."

This is one of those statements that seems so obvious that it should be regarded as a truism. And yet it's so often not the case.

I test in production. Since the tests are in production, they're fine, right? Seems like everyone's making a big deal about nothing!!

Jabor posted:

Nah, a zero for the code being too slow is just bad pedagogy. This is an academic exercise, not a programming competition.

Relying 100% on the autograder (and then farming out giving feedback on the actual code to the other students in the course instead of giving it yourself) sounds like a incredibly lazy prof.

Yes, he did say that it was a university course. This sounds about right for that. The professor would never lower themselves to actually look at any student classwork, that's what they have TAs and grad students for.

I can do `var foo = {undefined: undefined, null: null}` (or `var map = new Map(); map.set(null, null); map.set(undefined, undefined)`). `Object(foo).keys()` / `Object(foo).values()` (or `map.keys()` / `map.values()`) will return `[undefined, null]`.

Honestly, I'm disappointed that no one except Jabor is considering the case of business requirements changing. What happens when business decides that every number beginning with an even number is also even? Or 99 is even, because that's how they run sale prices? And even Jabor only mentions a strategy, and nothing else.

code:


string greeting = "Hello", name;
cin >> name;
cout <<  greeting << "World, " << name << "!";

For beginners, this is basically "uh I Guess I read and write by doing these weird arrows? Not sure why but ok?" And then you learn about manipulators you can use for clever programming tricks, but with No Idea what's even happening there. "Why does the magic word endl work, but also you're calling some kind of function called setw? I thought functions returned values, but I guess I can tell it to use a function or something?" And then you find out that cout and cin are the only places these <<s and >>s seem to work, except for maybe a couple other places where they mean Something Else?

Straight up inscrutable, I have absolutely no idea why someone decided "let's give new developers this magical footgun so they learn JUST ENOUGH to do stupid tricks, but don't know what is actually happening." They're powerful tools but they shouldn't be beginner tools.

Since Java is so verbose and tedious compared to newer languages it seems to have created a culture of relying on a lot of magic stuff to avoid as much hiring boiler plate as possible. To me coming from frontend and C# starting to contribute to our Spring based backend felt like a lot of magic incantations.

There is a similar problem with C#, certainly when it comes to EF and asp.net, but it doesn’t feel like it’s being taken as far as Lombok for example.

You're absolutely correct that it's a pain in the rear end, and you have to work around it. I was going to suggest Google Guice, but I don't know how widely that's actually used.

Dagger is a nice DI framework for Java / Kotlin that performs compile-time injection, which may well be much nicer depending on whether you actually need to be able to add/remove modules at runtime
