@JeroenVannevel I think my best result on that front was when I was shown our main spreadsheet and asked if there was a way to automate copying certain columns from selected rows into a table in an email, addressed to our trading team.

Took 30 minutes to go from request to research to coding to implemented

It's fun when that happens. It's strange to hear what people think is and isn't hard to do.

Aye. Of course, it's less fun the other way around. When they ask for something that sounds simple, but is actually really difficult

during interviews, I ask simple questions, like decide if a string is palindrome, or a number is prime. I used fizz buzz before, but everybody passed that, so it was useless

Otherwise you would have to remove elements from the array if there were excess elements.

But I'd say if candidates seriously return [[]] they are either really worth considering or trolls :P

I would say they were a troll unless they pointed out the loop hole AND gave a working example.

ok back to work now

Thanks for the insight, definitely something I'll take on board

skiwi

11:18

@janos What makes you decide that input validation is important though? The fact that it is a library class and intended to be inside a professional codebase?

Spirit week can't be explained, only experienced

Donald.McLean

Spirit week is a week at a High School, often leading up to "Homecoming" where special activities are planned to "raise school spirit"

Mostly it's fun, often silly stuff.

Mast

@Donald.McLean So it has nothing to do with the alcoholic kind of spirits?

A Red Herring

So basically its a load of activities to raise morale.

@Mast I would say getting drunk might raise some high schooler's spirits :^)

SuperBiasedMan

Actually on that note, what is homecoming? I've heard it on TV so many times.

Donald.McLean

@Mast Well, it's high school, so officially no.

@SuperBiasedMan Homecoming is a home game followed by a dance. The sport is usually football, unless the school doesn't have a football team in which case it's usually basketball.

SuperBiasedMan

11:47

@Donald.McLean Oh, that's much less dramatic than the TV made it sound.

Donald.McLean

It's often the first home game, or at least very early in the season. If possible, it's against a team that sucks so that the home team has a good chance of winning.

A Red Herring

Are there bald eagles involved?

For extra freedom points.

janos

@skiwi it does happen that I invite somebody because they have enough other good points, even with some WTFs. And yes, the library bit is meant as a hint. Candidates picking up on these things or not, are also part of the test

The thing about homecoming is that it's all about the extra "spirit activities" - the dance and all.

@SuperBiasedMan I haven't heard about the documentation thing for a while.

A Red Herring

If it remains completely optional Id ont' see the issue with havings ome aspects of a social network on SO.

Zak

And I'm pretty sure half the hypothetical example questions they showed in that post would get a response of: "Sorry, that involves privileged information that we're not allowed to give to random people on the internet"

SuperBiasedMan

I think it could've been planned as site agnostic, and just said it was being tested on SO or something. But maybe there's a ton more overhead there I'm missing.

A Red Herring

@SuperBiasedMan Remember that Stack Overflow is now the official name of the entire collection of sites (or at least the name of the company).

SuperBiasedMan

SuperBiasedMan

@ARedHerring Oh that's true... and mildly confusing.

11:57

@Mast don't ask me, they decided to change their name to it. I can't find a source but it was on the meta a few weeks ago

SuperBiasedMan

I think it'd work better if the teams vetted questions before they were visible to anyone else. That way if they don't want to ask them then no-one even realises they neglected to comment on private info stuff.

Mast

@ARedHerring Confusing indeed...

A Red Herring

@SuperBiasedMan Congrats! You just created ask.fm

@Zak Indeed.

SuperBiasedMan

@ARedHerring I don't think SO is under the illusion that they're making something brand new as opposed to a better system.

Mast

So basically they're going to re-organize how SE works...

Zak

"What's your hardware setup" - probably confidential

A Red Herring

I need to actually do some work today. AFK.

Zak

Or, at least, not explicitly public

SuperBiasedMan

11:58

Also does anyone use ask.fm as anything other than personal?

A Red Herring

@SuperBiasedMan yes, members of companies now use it as a generic Q/A site. See Riot Games and RiotLyte

Zak

And if I'm an employee, I'm not about to post information that may or may not be considered confidential

SuperBiasedMan

@ARedHerring That is... weird. I suspect they're heavily edited though

Ethan Bierlein

ask.fm is mostly like a worse version of Yahoo answers. Almost everyone at my school has an account. I still really don't know what purpose it serves when we have SE.

SuperBiasedMan

I'd be interested in teams from people who work on semi obscure code systems I have to interact with, but I'm pretty sure they're too small and niche for this unless teams actually gets big.

Zak

12:01

I mean, essentially, team Q&A is going to be about questions relating specifically to that company. Which, for anything technical and non-generic, is likely to be confidential.

And for anything non technical - company website

and for anything generic - SO

But hey, the non-Questions aspects seem like a decent idea

Ethan Bierlein

Sounds like an answer to that meta post to me ^^

SuperBiasedMan

I think it depends on how closed the company is. I work with a couple programs where the devs are really open, they've changed stuff for us and regularly communicate on their forums or google groups. SO Teams would be a more robust platform for that if they were interested.

I'm actually just less sure that many companies are going to be interested. I expect there'd be more open source people who did casual hobby projects.

But anyway, I gotta head for lunch. Later folks.

The result is, that the undefined numbers are at the beginning: perl -MData::Dumper -e 'print Dumper(sort {$a <=> $b} 3, undef, 2, 1);' $VAR1 = undef; $VAR2 = 1; $VAR3 ...

but hey I'll probably have to use swing for university and I really hate it. Maybe I can get it into a state where I can deal with it without shouting at everybody

Mat's Mug

@Vogel612 make a drag-and-drop designer a la WinForms! :)

Vogel612

14:25

Spare me!

Mat's Mug

lol

Vogel612

At least WinForms has a reasonable Layouting policy

Jacob Raihle

Maybe you can use JavaFX and embed it with a JFXPanel :^)

Vogel612

that's not the point

also JavaFX is a similar pain

Mat's Mug

@JacobRaihle haha sounds a bit like a WPFControlHost

Jacob Raihle

14:27

It would be a "swing" application, but yes I understand :(

Mat's Mug

if it's so old, perhaps it should be renamed "swung"

Jacob Raihle

Nono, it is obviously the noun they are referencing, as verbs do not exist in Java...

Vogel612

urk... here we go again

Mat's Mug

haha

Who the heck is the gorilla?

IntelliJ even has an annotation @MagicConstant for the crap swing is pulling

and it warns when you do strange stuff instead...

Mat's Mug

haha JetBrains rocks

Vogel612

but it doesn't recognize when an expression can only evaluate to a swing-constant

the craziest about that is, that they actually annotated the java API with the magic constants that can be used, possibly manually ...

damn you, travis!

We have:
- openjdk 1.6
- openjdk 1.7
- oraclejdk 1.7
- oraclejdk 1.8

but not openjdk 1.8 or oraclejdk 1.6

@Vogel612 are there any alternatives for java beside javafx and swing ?

Vogel612

14:45

little... eclipse (yes the IDE) have written their own windowing toolkit (swt), which is loosely based on the java API's standard "Abstract Window Toolkit" (awt)

that's about it for windowing and thick client stuff, unless you want to go closer to the metal and go for OpenGL

Heslacher

ok

Vogel612

Swing was around from the start

and JavaFX got added on the road to 1.7 IIRC

Heslacher

So I stay with using swing if I have to do gui stuff (although I don't want to)

Vogel612

Swing is fugly and JavaFX makes your code fugly because it imposes an at best mediocre structure upon you

@Heslacher usually, yes.

Mat's Mug

how hasn't UI improved in 20 years Java has been around?

Vogel612

14:48

oh JavaFX is shiny

Mat's Mug

> JavaFX makes your code fugly because it imposes a structure upon you

Vogel612

but the code you produce with it is imo a spaghettyish piece of junk

Jeroen Vannevel

fugly is still shiny in Java terms

Mat's Mug

@Vogel612 compare to winforms MVP and wpf MVVM

Vogel612

fx is more wpf

Mat's Mug

14:50

without MVVM

Vogel612

and winforms is more swing

@Mat'sMug with misunderstood MVC

and an entry point that rips your application into static context when you start up the GUI

Q: How to count hours with no "if"

I'm trying to do this in simple Code::Block using C++. So this is the code. #include <iostream> using namespace std; int main() { setlocale (LC_ALL, "LITHUANIAN"); int a, b, c; cout << "Hours : "; cin >> a; // 23, 15 = 1380, 900 cout << "Minutes : "; cin >> b; // 55, 50 cout << "How much minut...

Q: Rate my first effort with React, use of components, props and states

I've just created my first set of related classes in React and would like to get feedback from more experienced React developers. I've used ES and completely vanilla React. The application is a shopping cart where the cart item quantities update the totals. The one file situation is because it ...

@CaptainObvious we don't rate, we review.

Jeroen Vannevel

Bloody hell Amazon, put some javadocs in your jars

SuperBiasedMan

Huh, here's a question.

Code editing is not allowed for a suggested edit, always rejected. But should we do anything if the OP accepts the edit? (it's not invalidating any answers)

(this is not hypothetical: codereview.stackexchange.com/review/suggested-edits/46091)

Mat's Mug

14:54

I suppose that's how OP has it in their IDE then.. doesn't make the post any more on-topic though

Vogel612

If unclear, ask :D

SuperBiasedMan

The OP might think it's just a good suggestion. But I was thinking more generally, the editor just got told they made a good edit by the system, is it worth leaving a comment informing them not to edit code in future?

Mat's Mug

they wouldn't be ping'd

but yeah

SuperBiasedMan

You can @ping editors on posts they've edited.

Unless that's weirdly an SO only feature.

Mat's Mug

huh, I didn't know that
