Hi, just a plug for my favourite distributed computing project, [EMAIL PROTECTED], http://folding.stanford.edu/ (Unlike SETI [EMAIL PROTECTED] has a number of publications to its name... though, I guess SETI was the grand-daddy of the distributed computing projects :-)
Anyway, just a comment about the economics of running all these "old" computers, and it's something about which I am conflicted (the environmental damage of producing computers/disposing of them vs. the environmental damage of the electricity used by them). Four "old style" (hardware energy efficiency), Old World, and one NuBus Mac (6500s are PCI, right?) running 24/7 chew up a lot of energy. For the sake of argument (and, simplicity of calculation ;-), let's assume each uses 100 W/h. That's 400 W/h. Per day that's 24 h x 400 W/h = 9.6 kWh. Per year (365.25 d) that's 3506.4 kWh. At $0.10/kWh that's $350.64. Let's assume subsidised power (most electricity is (and is fossil fuel-produced) since the environmental costs aren't paid by coal/fossil fuel producers or electricity users, but are "paid" by all through the "tradgedy of the commons") at $0.075/kWh (very realistic price in NA) and that's $262.98/a. If you were to replace all four computers with one that'd be $65.75 and you'd save $197.24/a on the other three. For $200 USD you can pick yourself up a 400-500 MHz G4 on eBay (not shipped, granted), and it would do everything... run Seti faster than all of the OldWorld Macs together (or [EMAIL PROTECTED] :-) :-) :-), act as a server, DHCP server, firewall and wouldn't require BootX fiddling. If your box is a dedicated DHCP server, it's far more economical to purchase a cheap router (you can get them for $10 or $20 US). My wireless/wired router (which will consume more power than a wired router only) costs $10/a at $0.075/kWH if I assume that it draws the MAXIMUM 16 W its powersupply is rated for (it's doubtful it does) vs. my estimated $65.75 for a 100 W desktop. Anyway, that's my environmental-economics post for the day. It's a tragedy that "reuse" isn't always the best option in computers :-( :-( (especially when you consider how damaging it is to produce them and dispose of them). Eric.

How do I do all of that? _______________________________________________ yellowdog-general mailing list [email protected] http://lists.terrasoftsolutions.com/mailman/listinfo/yellowdog-general HINT: to Google archives, try '<keywords> site:terrasoftsolutions.com'
