iirc there was some high-voted contest question from around somewhere.... but yeah was something of an outlier/ anomaly...
ah maybe this one. sasha has been using the site for project euler questions with some success. (he asked the meta question cited by Evil)

Q: How to find the element of the Digit Sum sequence efficiently?

sashaJust out of interest I tried to solve a problem from "Recent" category of Project Euler ( Digit Sum sequence ). But I am unable to think of a way to solve the problem efficiently. The problem is as follows ( in the original question sequence has two ones in beginning , but it does not change the...

There is BF support at the codechef! I was not aware of that. But Rhino for JS :/

@Evil Well, whenever you change your mind, Computer Science Meta is there for you. We can also discuss your ideas here in chat, if you want.
@Evil I don't understand what you mean.

@Raphael there are the questions like this - this one is hot lately. So once I thought about writing a reference-like answer to this machine, and $a^2nb^n$ and ... pick any. A collection of machines with descriptions.
The downside is that people will not search ,so it doesn't prevent from the homework flow. They will not read the description, just copy and handle to the teacher... Rather bad idea.

Lol. Are you willing to proofread it? X]
The title "Do not post at CS.SE, your answers are here".
The next day after ebook goes viral, we will not get so much trafic here, but also this would be the day that the knowledge starts to fade.

@Raphael On a quick reading, it appeared that at least some of the codechef questions come with monetary rewards. I'm unwilling to answer such questions unless I get a cut of the reward.
