These are my links for 12 ago 2013 through 16 ago 2013:

• Epoptes – Epoptes (ΕπÏŒπτης  – a Greek word for overseer) is an open source computer lab management and monitoring tool. It allows for screen broadcasting and monitoring, remote command execution, message sending, imposing restrictions like screen locking or sound muting the clients and much more! It can be installed in Ubuntu, Debian and openSUSE based labs that may contain any combination of the following: LTSP servers, thin and fat clients, non LTSP servers, standalone workstations, NX or XDMCP clients etc. Patches for other distros are welcome.
• bcache – Bcache is a Linux kernel block layer cache. It allows one or more fast disk drives such as flash-based solid state drives (SSDs) to act as a cache for one or more slower hard disk drives. Hard drives are cheap and big, SSDs are fast but small and expensive. Wouldn't it be nice if you could transparently get the advantages of both? With Bcache, you can have your cake and eat it too. Bcache patches for the Linux kernel allow one to use SSDs to cache other block devices. It's analogous to L2Arc for ZFS, but Bcache also does writeback caching (besides just write through caching), and it's filesystem agnostic. It's designed to be switched on with a minimum of effort, and to work well without configuration on any setup. By default it won't cache sequential IO, just the random reads and writes that SSDs excel at. It's meant to be suitable for desktops, servers, high end storage arrays, and perhaps even embedded.
