Things I do in my free time.

dragon-oss

HDFS Driver for the Aliyun Open Storage Service. Allows you to run MapReduce over Aliyun OSS.

raft

An implementation of the RAFT consensus algorithm in Scala.

hashset.c

A hashset implementation that uses contiguous memory space. This allows applications to dump and load hashsets using mmap at run-time, or using objc and ld at compile-time.

Box Lid

A jQuery plugin inspired by Toybox's navigation menu. See it in action here

Beam

A buggy websockets-based drag-and-drop file sharing tool that I wrote for fun using Amazon's S3.
