Comment rsync + OpenSolaris (ZFS) w/time slider (Score 3, Interesting) 421

Nighly (or more frequently, if you like) rsync to an OpenSolaris server running ZFS w/ Time Slider.

Quality versioned backups with little effort, plus data integrity (checksums built into the filesystem), compression, and (if desired) RAID-Z(2) goodness! In addition, the provided time slider interface allows easy browsing of versions.

Just my 2c...

I'm a Unix wizard.

That's like saying that you're 'cool' or a 'maverick'. If you call yourself one, chances are, you aren't.

Of course, you could spend the ten seconds to google the guy.. Let's see.... MIT media lab; Worked at MIT since '86, now at Harvard... "8 years experience architecting and administrating large networks of Unix workstations." I think he can use the label if he wants to. :)


Submission + - NASA to build largest Supercomputer ever ( 1

Onlyodin writes: The National Aeronautics and Space Administration (NASA) has given the green light to a project that will build the largest ever supercomputer based on Silicon Graphics' (SGI) 512-processor Altix computers.

Called Project Columbia and costing around $160-million, the 10,240-processor system will be used by researchers at the Advanced Supercomputing Facility at NASA's Ames Research Center in Moffett Field, California.

What makes Project Columbia unique is the size of the multiprocessor Linux systems, or nodes, that it clusters together. It is common for supercomputers to be built of thousands of two-processor nodes, but the Ames system uses SGI's NUMAlink switching technology and ProPack Linux operating system enhancements to connect 512-processor nodes, each of which will have more than 1,000G bytes of memory.

Submission + - Chernobyl Mushrooms Feeding on Radiation

cowtamer writes: According to a National Geographic Article certain fungi can use ionizing radiation to perform "radiosynthesis" using the pigment melanin (the same one in our skin that protects us from UV radiation). It is speculated that this might be useful on long space voyages where energy from the Sun is not readily available.
