- Like C, but with garbage collection, memory safety, and special mechanisms for concurrency
- Pointers but no pointer arithmetic
- No header files
- Simple, clean syntax
- Very fast native compilation (about as quick to edit code and restart as a dynamic language)
- Easy-to-distribute executables

Grout is an HTTP-based front proxy that delegates portions of a url path space to other web applications. This allows for a web application to be composed of a collection of micro-services.
Beyond routing based on url, language or ip-based region, Grout provides downstream services with a unique per-request X-Grout-Id
and a per-session X-Grout-Session
header for simple cross-service sessions.
Presently 99designs.com is composed of 2-3 different web applications. Varnish sits in front of these web applications and dispatches requests to the appropriate backend based on some complicated regular expressions and a large chunk of complicated VCL.
The purpose of this gem is to consume the JSON that KISSmetrics exports to an S3 bucket, and transform it in a variety of useful ways.
The core features are:
- JSON compiler : Aggregates all KISSmetrics JSON files in a directory, into a single (nonstandard) file.
- JSON to JSON converter : Converts a nonstandard JSON file into standard format.
- JSON to CSV converter : Converts a nonstandard JSON file into a CSV file, where each row is an event/property/alias.
- Reimporter : Takes a nonstandard JSON file, and an API key, and sends the data in the JSON file to the product using the KMTS gem.
