FIASCO—An Open-Source Fractal Image and Sequence Codec

FIASCO provides state-of-the-art image and video compression.

FIASCO provides a powerful compression library that is intended to replace JPEG and MPEG for low bit-rate applications. FIASCO is an asymmetric compression method; you get software-based, real-time decoding at the cost of slow encoding times. FIASCO is especially suited in an application context where images or videos are compressed only once but requested and decoded several times (e.g., world wide web applications). Finally, if FIASCO were to be combined with an open-source sound and speech compression (e.g. Vorbis, see Resources), a complete video compression system for low bit rates would be available for free.


@aa:Ullrich Hafner (, has been a software engineer in the software management & design AG (sd&m), Germany since 1999. He developed FIASCO for his PhD thesis Low Bit-Rate Image and Video Coding with Weighted Finite Automats (see Resources) from 1994—1999.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
