Wunderbar is a program which is able to identify mislabeled samples in genotype data when a few extra independent genotypes are available ("genetic barcoding"). Wunderbar calculates the likelihood that genotype mismatches have occurred by chance. It is capable of reliable and sensitive detection of sample mismatches and swaps even in the presence of numerous genotyping errors and in the presence of linkage disequibrilium between the individual genotypes. It only requires a few SNPs to work well.
The WiKID Strong Authentication System is a highly scalable, secure two-factor authentication system. It is simple to implement and maintain, allows users to be validated automatically, requires no hardware tokens, has a simple API for application support (via Ruby, PHP, Java, COM, Python, etc.), supports multiple domains, and supports replication for fault tolerance and scalability. It also supports mutual /host and transaction authentication, wireless tokens only domains, locked tokens (to your PC), anti-keystroke logger keypad PIN entry, etc.
Foodsoft is online software for a non-profit food coop. It features a product catalog, order cycle management, accounting, and tasks. A food cooperative is a group of people that buy food from suppliers of their own choosing; a collective do-it-yourself supermarket. Members order their products online and collect them on a specified day, and all put in a bit of work to make that possible. foodsoft facilitates the ordering and administration.
Unicorn is a Unix and LAN/localhost-optimized fork of the Mongrel HTTP server. It takes full advantage of functionality exclusive to Unix-like operating systems. It will reap and restart workers that die from broken apps, and there is no need to manage multiple processes yourself. Load balancing is done entirely by the operating system kernel. Requests never pile up behind a busy worker. The server does not care if your application is thread-safe or not, as workers all run within their own isolated address space and only serve one client at a time. All Rack applications are supported along with pre-Rack versions of Ruby on Rails via a Rack wrapper. It also supports atomic log cycling, nginx-style binary re-execution without losing connections, before_fork and after_fork hooks, and optional copy-on-write-friendly memory management.
Coco is a code coverage utility for Ruby. It can be used from RSpec or unit/test with a simple "require 'coco'". It works with standalone Ruby or with Rails. It displays the names of files that are uncovered on the console, builds a simple HTML report, and reports sources that have no tests. It is UTF-8 compliant, configurable via a simple YAML file, and has colorized console output.
Rainbows! is an HTTP server for sleepy Rack applications. It is based on Unicorn, but designed to handle applications that expect long request/response times and/or slow clients. For Rack applications not heavily bound by slow external network dependencies, consider Unicorn instead as it simpler and easier to debug.
