What to Do With a $99 Wall Wart Linux Server 346

Posted by kdawson from the best-computer-is-an-invisible-computer dept.
Guanine writes in with a follow-up to our discussion a few months back on the SheevaPlug: 1.2-GHz ARM-compliant processor, 512 MB DDR2, 512 MB flash, USB 2.0, gigabit ethernet, in a package the size of a wall wart, for $99. Saul Hansell's Bits Blog in the NY Times talks about a few applications for such a device, whose price point Hansell claims will drop to $40 before too long. "The first plausible use for the plug computer is to attach one of these gizmos to a USB hard drive. Voila, you've got a network server. Cloud Engines, a startup, has in fact built a $99 plug computer called Pogoplug, that will let you share the files on your hard drive, not only in your home but also anywhere on the Internet. ... [Marvell's CEO said] 'Eventually you won't see the plug. We want this device to be in your TV, your stereo system, your DVD player.'"

      I hope they don't have the NSLU2 disadvantage of not powering on automatically after a power failure.

      This annoyance makes the NSLU2 unsuitable for remote monitoring where the electricity supply is unreliable.

      The NSLU2 software distributions are also crippled (stripped down versions of utilities that break things like CPAN). Hopefully this one is more standardized and less unique.

    What to Do With a $99 Wall Wart

    Wall warts are usually nothing to be concerned about unless they grow or spread rapidly. Usually you can just freeze 'em off--just be sure to get all the abnormal growth cells. It's a common wall growth caused by HPV (Hewlett Packard Virus).

    Linux Server

    Your warts are functioning as Linux servers? You may need to see a specialist ... and until you get that checked I would refrain from any prolonged exposure to GPL software.

    Count yourself lucky, it could be worse. My friend once had a case of $10,000 Server Room Herpes Microsoft Servers that kept him up all night ... not something you want on your resume.

    I applaud anyone who successfully markets this product ... the name is a bit of an obstacle. "Wall Hugger" or "Plug Pal" or even "Linux Lump" might have been more prudent for coining.
