Tutorial: Create an NFS-like Storage Server with GlusterFS on Ubuntu 12.10

Up
vote
Down

This tutorial shows how to set up a standalone storage server on Ubuntu 12.10. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA. read more...

Down

Pipelight, which allows to run your favorite Silverlight application directly inside your Linux browser. The project combines the effort by Erich E.

He worked on a set of Wine patches to get Playready DRM protected content working inside Wine and afterwards created an Ubuntu package called Netflix Desktop. This package allows one to use Silverlight inside a Windows version of Firefox, which works as a temporary solution but is not really user-friendly and moreover requires Wine to translate all API calls of the browser. To solve this problem we created Pipelight. read more...
