As we do each quarter, we want to celebrate those Stack Exchange sites that have been with us for a whole decade, which means some of the top contributors to those sites could have still been watching cartoons after school back when they first launched. This crop of sites will help you understand how your brain works, what’s sporting outside and inside, when to hold ‘em, and when to fold ‘em.

Computer Science

Our flagship site, Stack Overflow, covers programming, so what’s left for the Computer Science site to cover when we remove that? As it turns out, plenty! Algorithm design and analysis, formal systems, distributed computing, computational geometry, cryptography, and more. Students, researchers, programmers, and teachers have all asked us questions when they need a bit more science to solve their computer problems.
