Seldom do we get to hear stories of the bumps and bruses earned by a popular website during its formative years. Ross Snyder, a Sr. Software Engineer at Etsy, changes that with an engaging talk he gave at Surge 2011: Scaling Etsy: What Went Wrong, What Went Right. Ross gives a detailed and honest account of how Etsy went from a raw startup in 2005, to a startup struggling with their success in 200
Facebook Timeline is audacious in scope. It wants to compile a complete scrollable version of your life story from photos, locations, videos, status updates, and everything you do. That could be many decades of data (hopefully) that must stored and made quickly available at any point in time. A huge technical challenge, even for Facebook, which we know are experts in handing big data. And they bui

The module uses string permutations to find method names that are close to the one called with a typo. It also discusses enhancing TypoFixer to prompt the
The Heroes of Java: Ward Cunningham The 12th part of my "Heroes of Java" interview series is somehow, let's call it special. It's not about an active member of the Java community in the sense of a well known evangelist, programmer or speaker.
