About

MobileDyne Systems Inc was incorporated in Georgia in 1994 as a contract software development company. Since then, we have produced production transaction processing systems for corporate clients ranging in size from multi-billion dollar companies like BellSouth and FedEx, to venture capital funded start-ups.

Some projects have been close-to-the-metal performance-critical systems, such as rendering distinct thirty frame-per-second broadcast-quality television streams on each one of several thousand rackmount headend servers for The Weather Channel. We also designed and wrote the C++ implementation of their satellite data transmission protocol, using multiple priority queues to handle both gigabyte size batch file transfers and ultra-high priority messages such as television framing interupts and tornado warnings.

An innovative feature of the satellite protocol is the availability of a built-in software Forward Error Correction (FEC) codec that can transmit gigabyte files with encode blocks containing hundreds of kilobytes each, protecting the data from RF interference that lasts thousands of times longer than the hardware's Viterbi encoding can handle. This high-performance FEC codec can perfectly reconstruct error-free files even when 10% to 30% of the transmission is garbled by passing aircraft or military radars. It is written in C and C++ with a little assembly language for some of the matrix primitives. An subsequent re-implementation of this FEC technology was later used on an embedded CPU for transmitting real-time video for Foxtrot Robotics.

Prior to creating MobileDyne, our founder wrote large computational fluid dynamics and radar simulations on the biggest computers in existence, such as Cray XMP, Cray II, and Cyber 205 vector machines. Two years of this work was on classified projects in Lockheed's "black hole". Following the computational aerodynamics work, he was one of three people who wrote the first commercial Unix system in BellSouth, a system that activated cellular telephones in 11 states and handled more than 40,000 activations per day.

Since 2003, most of our projects been web systems. Web development is generally done using the Ruby On Rails frameworks, or its cousins such as Staticmatic and Merb. Ruby on Rails has an immense library of plugins and extensions that enable rapid implementation of solid web applications. We deploy Rails on Apache or Nginx reverse proxies, using Phusion's Passenger, Mongrel, or Thin application servers.
