This week's book giveaways are in the Cloud and AI/ML forums. We're giving away four copies each of Cloud Native Patterns and Natural Language Processing and have the authors on-line! See this thread and this one for details.
Yesterday we launched our SDK for Android developers. It's lightweight (only 4kb), works kindly with other SDKs, FREE and it WILL help increase your user base and fetch more downloads for your app from the Android market.
