The OpenWeatherMap PHP SDK by Christopher Norton allows developers to integrate the OpenWeatherMap APIs into their PHP applications. So far, only the OpenWeatherMap Current Weather Data API is provided, but others will be added in the future.
Samsung and the Tizen Association recently made the Tizen Software Development Kit for Wearables available from the Tizen developer web site. The SDK supports any wearable running Samsung's Tizen operating system, but that's an extremely limited number of devices at the moment, with just the Samsung Gear 2 and Gear 2 Neo smartwatches filling the space.
Onset, a supplier of data logging devices, just launched the HOBOlink® Web Services API, that enables anyone to easily build applications around weather, energy and environmental data gathered from the Onset HOBO® U30 monitoring systems, hardware you install in your environment which can share its status up to Onset's system.
For as long as people have been grabbing a board and trying to catch some waves, attempting to predict surf quality has been considered an art. Spitcast is trying to turn the art of prediction into the science of surf. Jack Mullis, the founder and developer of Spitcast, has been surfing for years. In 2005 he decided to combine his knowledge of surfing with his degree in Engineering Physics and create a unique algorithm that can predict future surf conditions by using Java and MySQL to cross reference NOAA regional weather data with observations at specific surf spots. This process has been shown to produce predictions accurate to 1 foot standard deviation. With the Spitcast API, this data can be transformed into custom applications.
