For many of us Twitter has become an essential communications utility. Since experiencing scalability problems in 2010, Twitter has moved to a loosely coupled service oriented architecture based on the JVM, allowing it new levels of scalability and feature agility. Twitter engineering recently reported a new record throughput and took time out to describe their new architecture.
Twitter has open sourced its Effective Scala guide. The document is on GitHub and is licensed under CC-BY 3.0.

Customers use a wide variety of technologies for communication and expect the companies they deal with to do the same. This means the same message may need to be sent to a mailing list, a Twitter account, an IRC channel, and a Facebook page. To make this easier, developers can use the Broadcast library for Ruby or its .NET clone, nBroadcast.
Last week SpringSource released a first milestone for Spring Social, a Spring-based template for accessing Twitter, LinkedIn, Tripit and Facebook from within Java programs. Rather than exposing generic, URL-based APIs, the Spring Social APIs are designed specifically for each site and make integrating with those sites straight forward. InfoQ examines the new API as well as some alternatives.
Rick Strahl has created CodePaste.NET, a website that allows .NET code snippets to be shared among social networking and IM users.
As part of its virtual panel series, InfoQ has brought together scalability and performance architects from some of the biggest and most visible projects around, to let us into their secrets for achieving results the rest of us would just dream of.
