Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 155 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Wow — was cited by "Wait, Wait" as a reference this weekend. NY Times picked it up, too:

It was a big week in science. Physicists at the Large Hadron Collider say they may have found the “God particle,” and one computer scientist came up with a new way of finding:

A. Waldo
B. The meaning of life
C. Someone to kiss on New Year’s Eve
D. His one missing sock


(A) In a write-up on, a computer scientist used the imaging software Mathematica to come up with an algorithm that can find Waldo in any image. This development will have serious implications for United States surveillance operations if terrorists ever start wearing stripy sweaters and red stocking caps.

And the SO post: How do I find Waldo with Mathematica? – Arjan Dec 18 '11 at 14:08
It appears that it wasn't actually used in the show, just on the blog. – Brad Gilbert Dec 18 '11 at 17:03
uh oh... Not sure if that's a serious article or not, but it exemplifies the classic disconnect between science and news reporting. As my comment there says, it works for that image, not any image, as is claimed in the article. Nevertheless, that is a good answer. – Lorem Ipsum Dec 18 '11 at 17:15
If you know the show, it's not serious. The point is that Stackoverflow is mentioned, not the rigor of the citation or the generality of the answer. – duffymo Dec 18 '11 at 17:59
If you'd stopped right after "D. His one missing sock" you could have let someone answer it. Then it would have fit into the format, right? – Brett Champion Dec 19 '11 at 3:37
Actually, I didn't include the question or the answer. Someone else added it for me. – duffymo Dec 19 '11 at 10:15
Actually, you didn't include a lot of detail at all! ;-) – Arjan Feb 3 '12 at 20:27
TIL we have a spoiler tag which only reveals text on hover. How odd. – meagar Aug 29 '12 at 19:27
lol this post reminded me of the time I felt like an idiot for asking what "NPR" meant in Programmers.SE beta days because all I could think of was "National Public Radio" – Rachel Aug 29 '12 at 20:02
Interesting...SO is mentioned in the big public and the only thing I really care about is "Please stop calling Mathematica an 'imaging software'". – Time Traveling Bobby Feb 5 '13 at 10:07
