A free, open, and documented weather forecast API, built as a compatible alternative to the Dark Sky API.
Weather forecasts are primarily determined using models run by government agencies, but the outputs aren't easy to use or in formats built for applications. To try to address this, I've put together a service (built on AWS Lambda) that reads public weather forecasts and serves it following the Dark Sky API style. It is not a reverse engineering of the API, since their implementation relies on radar forecasts for minutely results, as well as a few additional features. The API aims to return data using the same json structure as what Dark Sky uses.
Free API keys are capped at 20,000 API calls per month (once every 15 minutes).
A distributed database that speaks MySQL's dialect of SQL and wire protocol on the front end, and is a fully distributed database system on the back end. Automatically shards databases efficiently. Implements ACID compliant distributed transactions for consistency.
