@trichoplax This is interesting. I don't have the attention span to fully comprehend this at the moment but I'll continue to consider it.
Oh hey, it's time for another "help Alex help his girlfriend do probability." You flip a fair coin three times. What's P({at least one head} intersect {odd number of heads}^C)?
@AlexA. My own doubt at the moment is whether there is too much overlap. If there isn't, I like the idea of distinguishing between the two contest types
@Geobits I guess you need something oil based. Acetone will dissolve some plastics - I don't know whether that is reversed when the acetone evaporates, and whether that could leave an oil based dye incorporated into the surface
Yea, dyed would be best. I just got a cube and there just isn't enough contrast between red and orange. I want to deepen the red up. It's a stickerless cube, though, so painting it would ruin the aesthetic.

When I see other submission, I feel like there's something wrong with my code... But then, I remember that's Lua, and there's isn't all these fancy functionnalities :'(
It was a lot of fun, took me some time actually.

Plan Your Next Movie
This will be a code-golf challenge.
Introduction
You're a director and you're planning your next movie. The studio has given you a maximum budget and also set the running time of your movie. Now you have a bunch of scenes to choose from. All scenes have a length, a fix...
In case there's any doubt: Nan = Non-numeric datatype for the purposes of this challenge.
Write a program or function that takes a matrix / array as input, as well as a list of column indices.
The challenge is to remove the rows where all elements in the specified columns are Nan. It doesn't...
Little 'bout my age: far from that of B
Yet in my syntax, you will find some C
The way I treat vars, that is much like D
I do take objects, but I'm not like E
If it starts with F, you'll know it's not me
Now I challenge you, just what could I be
I guess this should be fairly easy f...
Random question: If you have earned 196 rep today and someone upvotes an answer of yours, then promptly removes the upvote, will you have 196 rep or 190?
I'm puzzled that I got 205 points on the day rather than 215. There was one accept, and enough other upvotes after the upvote-unupvote at 10:19 that I would have expected to score 215, not just 205. Or is there something else going on that isn't showing up — but if there is, why isn't my rep ta...
I got downvoted on Oct 6 and Oct 27. I hit the rep cap later those days, so I didn't lose any rep from the downvotes. Both downvotes got reversed on Oct 28, but I hit the rep cap that day as well, so I didn't gain any rep from the undownvotes. Today, my rep got recalculated. The system decided none of this was fair and made the original downvotes count as -2 each.
You love watching the snow falling outside, but you know it won't be snowing much longer. You could take a video, but decide to make a snow animation so ... um ... you can practice your animation skills!

@LuisMendo Haven't made a lot of progress lately. Every time I could start writing them, I think I should do x first, since it could potentially invalidate a large portion of the docs...
@Dennis Your cell provider pushes ads to your phone? Aren't you already paying them for service, so they're just extracting additional money? Or am I confused?
My team is harassing me about the page lifecycle in ASP.NET because they think I understand how it works, and all I can tell them is "Put it in Page_Load. Does it work? If not, put it in Page_Init. Does it work now?"
@Dennis :-o I had never heard of those messages actually being sent. I thought they were onbe of those things that are in the UMTS/LTE standards that never get actually used
The task is simple: consolidate an array of ints. Consolidating this array consists of the following:
All instances of 0 need to be moved to the end of the array.
There should be no 0s between the non-zero integers.
All non-zero indices should retain their order.
Challenge

At least the operator could have written the opening ¡ and the accented ó properly. The bad spelling would annoy me even more than receiving the message
Your job is quite simple, write a program that prints Hello, world!, that when twisted creates a program that prints Twisted!.

The twisting algorithm is very simple. Each column is shifted down by its index (col 0 moves down 0, col 1 moves 1, ...). The column shift wraps...
@LuisMendo The Spanish here is way worse though. The pronunciation isn't as weird as in Argentina or Uruguay, but we borrow a few idioms from the Guaraní language.
@VoteToClose Is your "consolidate an array" computationally expensive enough to result in meaningful differences between programs? Your example Java program is already really fast at less than 500ms, and that could easily be running into boundary conditions of random disk access and the like ...

@quartata Everything but the most popular languages gets no votes. The majority is interested in getting rep fast, not answering challenging questions or providing thoughtful answers to anything. Even bounties get ignored, because it's easier to answer a few LMGTFY questions to got more rep than any bounty faster.
For any other question, there's basically just a) ignore or b) downvote.
@quartata It goes like this: 1) Post easy duplicate question ("can I haz code?!"), 2) easy, almost 100% code answers fly in 3) Days later, after many answerers have gained rep from that question, it gets closed as dupe.
