The Internet of Things is hear today and the IETF has begun a number of standardisation efforts in this area. Notable amongst them is the Constrained RESTful Environments (CoRE) working group, which is looking to provide REST approaches to constrained devices. There's also a Java project to support this work.
When we started building a new Web API for our business we wanted to build a really great API and the answer on Internet was to build a RESTful API, Amy Palamountain revealed in a recent presentation at TechEd in New Zealand when sharing her experiences of how to build a RESTful API based on the core ideas of HTTP and the web.
The recently released RAD Studio XE5 provides support for Android, iOS and Rest client including the ability to build prototype and native apps in standard C++ or Delphi without any need for multiple projects and schedules.

Use server driven content negotiation, but enhance the response with links to alternate versions and formats of the representation, thus letting the client choose which URIs to follow due to its needs Howard Dierking recently wrote when comparing his newly gained experiences working with designing the next major revision of the NuGet API, V3, with his thoughts almost a year ago.
Recently, Tom Dale, one of the creators of ember.js, wrote an article that re-kindled a brewing debate on the need for progressive enhancement. This is a quick look at the different views on the debate.

Recently Steve Jones from CapGemini commented on some text in a Nokia API project on github which indicated that designing and documenting APIs for REST based services was no longer required and that HATEOAS was sufficient. Given Steve's previous comments on IT valuing technology over thought, this was something he needed to call out as bad practice.
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.
"Don't version unless you absolutely must, and it is rare that you absolutely must" says Mike Amundsen in a series of API design workshops he held recently. Amundsen describes the "USE" paradigm for API design focussing on usability, scalability and evolvability. He describes the three most common styles of API implementation and how they compare to these principles.
Many of the presumptions of how slow and resource-demanding "Fat” XML is compared to JSON’s lightweight payload do not hold up to a test David Lee, lead engineer at Marklogic, states after running a "crowd sourcing" experiment with 33 different documents and almost 1200 tests on a multitude of browsers and operating systems.
Earlier this year Ganesh Prasad discussed the concept of thinking of SOA as "Dependency-Oriented Thinking". Based upon further interactions and involvement with real-world use cases, Ganesh has come up with a dozen principles which he believes can help successful SOA.
Node.js has built a user-base and reputation for fast and scalable back-end systems. In a recent edition of the Nodeup podcast, four engineers share their experiences developing APIs using the platform. The conversation covers a range of key concerns including API design, security, testing, documentation, schemas and streaming. But advertising your API as RESTful may not be a good idea.
