Code listed isn't necessarily complete or a usable product. The point is that the resource linked is mostly code and code that a beginner with a grasp of the basics could learn something from.
# My stuff
- https://github.com/bitemyapp/bloodhound Elasticsearch, mostly datatypes to describe Elasticsearch's query API and JSON parsing/generation.
- https://github.com/bitemyapp/blacktip Distributed k-ordered unique id service. Directly mimicking Flake which was itself based on Snowflake. Not correct/safe as I'm not using the system's monotonic clock.
# Users that write code people should learn from
- https://github.com/michaelxavier
- https://github.com/nikita-volkov somewhat advanced but pokes some interesting stuff
# File operations
