ZFS. ZFS was originally implemented as open-source software,[dubious ] licensed under the Common Development and Distribution License (CDDL). The ZFS name is registered as a trademark of Oracle Corporation.[3][better source needed][4] OpenZFS is an umbrella project, serving as the open source alternative to ZFS.[5][6][7] Features[edit] Data integrity[edit] One major feature that distinguishes ZFS from other file systems is that ZFS is designed with a focus on data integrity.
ZFS data integrity[edit] For ZFS, data integrity is achieved by using a (Fletcher-based) checksum or a (SHA-256) hash throughout the file system tree.[18] Each block of data is checksummed and the checksum value is then saved in the pointer to that block—rather than at the actual block itself. When a block is accessed, regardless of whether it is data or meta-data, its checksum is calculated and compared with the stored checksum value of what it "should" be. ZFS and hardware RAID[edit] Software RAID using ZFS[edit] Tron Legacy (2010) Year: 2010 Tron Legacy permalink I spent a half year writing software art to generate special effects for Tron Legacy, working at Digital Domain with Bradley "GMUNK" Munkowitz, Jake Sargeant, and David "dlew" Lewandowski. This page has taken a long time to be published because I've had to await clearance. A lot of my team's work was done using Adobe software and Cinema 4D.
The rest of it got written in C++ using OpenFrameworks and wxWidgets, the way I've always done it with this team ;) Uniquely however, Digital Domain's CG artists were able to port my apps over to Houdini for further evolution and better rendering than OpenGL could ever provide. Special thanks to Andy King for showing me that what seasoned CG artists do at DD is actually not so far off from what's going on in the Processing community.
Interview with GMUNK about the team's process In addition to visual effects, I was asked to record myself using a unix terminal doing technologically feasible things. Fireworks, mmmm.

Imagine the pace of innovation, change and breakthrough that could happen if supercomputing was made affordable, accessible and adaptable to the average developer. It’s a dream that isn’t far off becoming reality with the ‘Parallella’ – a $99 credit-sized ‘supercomputer for everyone’ that has just over 1 day left to reach its funding goal of $750,000. Should it reach its goal, the team behind the Parallella, Adapteva, say the world would gain access to cheap and open-source parallel-computing hardware, software and development tools.
Parallel computing is a form of computation in which many calculations are carried out simultaneously. (Wikipedia) Specifications The Parallella computer board will, if funded, comprise of: A dual core ARM A9 CPUEpiphany Mutli-core Accelerator1GB RAMUSB, Card Reader & Ethernet The operating system powering all this? If that all sounds a bit, well, standard, fear not. Support Parallella Parallella Supercomputer on Kickstarter.
