  1. The new mail server is almost finished.

    27 June 2007

    Thanks to Lyssa and a quick run to Micro Center on Monday night, I had enough parts to put together a new mail server who seems to want to be named Akara. I'm not sure if Akara is male or female, but Akara is busily processing the backload of SMTP attempts that have piled up since Monday. I'm going to let her burn in overnight and then tomorrow I'll connect the drive that contains the original mailstore and start reconstructing accounts.

  2. This could make me go back to using desktop cases.

    14 June 2007

    The retrocomputing enthusiasts over at briel.com are developing a desktop case that I really, really would like to get my hands on after they start producing them: It looks like the chassis of an Altair 8800, from the late 1970's. That's right, the very first 'personal' computer, complete with LEDs and toggle switches on the front panel. It's an ATX style case with a power supply that can drive up to a Pentium-4 system, and has enough quiet cooling to keep it from catching on fire. The drive bays are hidden behind the front panel, which has its own …

  3. FIXED: A late 20th century grimoire?

    30 March 2007

    This is one of the neatest art hacks I've seen in a while. Let me explain:

    Books are ultimately tools for storing information in a non-volatile manner for ease of transportation and reference. They're a relatively low bandwidth medium, limited by how fast the reader can turn the pages and the rate at which the visual cortex processes the characters, but are remarkably stable. Diskettes, on the other hand, are a more informationally dense storage medium, weigh less, and take up less space. They are more vulnerable to mistreatment, however: A fingerprint in the wrong place can wipe out large …

  4. Just when you thought you were hardcore...

    06 February 2007

    The more densely packed computing circuitry becomes, the fast it can run, in part because the connection paths are so short. Until room-temperature superconductors are invented, passing an electrical current through a physical connection, no matter how short, will prevent the current from running at the speed of light due to the phenomenon of electrical resistence. Another problem arises as a result of densely packing circuitry: Heat. Lots of heat.

    This is a problem that can't really be eliminated, because heat is a natural manifestation of entropy. When you lose decoherence in anything for any reason waste heat is generated …

  5. A new world record!

    25 January 2007

    The hacker spirit perseveres in all things, especially when it comes to squeezing every last compute cycle out of one's hardware. OC Team Italy set a new world record recently by overclocking a Pentium-4 processor core to 8.0GHz. The CPU they used in their grand experiment is a model 631, and runs natively at 3.0GHz. Their secret sauce to keep the unit from going Chernobyl? Liquid nitrogen.

    On one hand, this horrifies the sysadmin in me. On the other.. rock the hell on. A round of beer's on me if I ever meet you guys face to face …
