This is really unacceptable and so easy to solve, had they even bothered.<p>But it has been known for years that Facebook just cannot (or will not) manage its application development process. I remember reading somewhere that they developed build tools that take multiple versions of the same static library and mangle the symbols so that all versions can be linked into a single binary and there are no symbol collisions - all this to allow developers to use whatever version they started of, and god forbid, require some sort of review or cooperation between developers.<p>It is very sad to me that so many companies (start up or otherwise) aspire so much to have the same work methodologies as this company.
