Life's full of lessons. If you don’t try, you can't fail – but you can’t succeed either. We learn from our mistakes. “Mobile Development: Lessons Learned” is where mobile developers come to learn and grow, share their insights and past indiscretions. From facepalm-worthy bugs to the road we wish we hadn't taken. Here we share ideas, experiences, best practices and so much more. They say you haven't been a real New-Yorker until you've killed a cockroach with your bare hands, and you haven't been a true full-fledged developer before you've forgot one tiny little ‘=’ and assigned when all you really wanted is to compare. We’ll talk about the major expensive bugs (integer overflow that crashed a spaceship, anyone?), the small ones (copy-paste being the devil's invention and all) and the truly terrifying ones (ever heard of the system that thought a cloud was a missile and nearly started an all-out war?). Whether you've spent hours tracking down the most trivial of bugs, looked at a piece of code that by all means should have worked or simply regretted taking your product in one direction a little too late, “Lessons Learned” is a safe place for all. We’re not here to judge, we’re here to learn.
