Apt-Cacher-NG - HTTP download proxy for software packages. Apt-Cacher-ng is a software package that keeps a cache, on the disk, of Debian/Ubuntu Packages and Release files.When an apt-get like client issues a request for a file, Apt-Cacher intercepts it and if the file is already cached it serves it to the client immediately, otherwise it fetches the file from the Internet, saves it on the cache, and then serves it to the client. This means that several Debian machines can be upgraded but each package need to be downloaded only once.

There are things common among all cars as there are among all Linux distributions: all cars have an engine, and all Linux distributions share the Linux kernel and many of the GNU utilities.

Marvell announced today a new type of computer. It's about the size of an AC to DC converting wall outlet plug, but is really a full SoC with a 1200 MHz CPU, built-in 512 MB Flash, 512 MB DRAM, Gigabit Ethernet and USB 2.0 support. It runs small versions of Linux, consumes about 5 watts max while allowing remote users (presumably those authorized by the owner) to access data stored on the device from remote locations including local intranets or over the Internet. The $49 device opens up a wide array of extremely low-power, low-volume, always on applications.
