First Beowulf Cluster in Space

When a satellite's image-gathering power exceeds the bandwidth available to transmit the images, a Linux cluster right on the satellite helps decide which images to send back to Earth.
Launch into a New Space Era

From an engineer's perspective, X-Sat and its PPU couldn't succeed without Linux: almost all current application developments in the area of remote sensing use Linux, as do most modern cluster systems. So, sometime in early 2007, if you tilt your head back at the right time, you might be caught on camera, processed and downloaded, thanks to Linux.

Ian's been using Linux since about 1856 and weaned his kids at the penguin's electronic teat. His interests include satellites and signal processing, and his career objective is to lose his job and become a missionary in China.

Although Timo didn't try to wean his daughter on the penguin, he uses Linux for most of his number-crunching problems on Beowulf clusters and in the future even more extensively in space. Timo's research focus is remote sensing and various image-processing problems, well, unless he's gone traveling.

Bharath designs high-performance systems for Hewlett-Packard. Not being very high-performance himself, he relies on the pet monkey under his desk to come up with hardware designs. Occasionally, it also writes articles for magazines with penguins on their cover.


One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
