How do you versioning your software?
This is so embarrassing, I didn't know well about Software Versioning before reading the MongoDB book. Because, I mostly worked for web-service companies which don't develop the software product and care about software versioning. (Other country companies may not, but at least 'korea web-service' companies does.)
Anyway, I recently learned many things while translating the book, 'MongoDB: Definitive Guide'. :D
P.S., The Korean version of 'MongoDB: The Definitive Guide - O'Reilly Media' is coming soon!
