haha.. I was at a lan party once in wisconsin, they had a/27 (30 useable IPs) routed on a T1 line. They were a bunch of goons, and didn't know how to setup DHCP or NAT. They got to the end of the allocation (low bit gateway) and just kept assigning more to people.. first the broadcast, then the next network number, etc etc.. they wondered why the network got wierd and slow when some guy had his box set to be the broadcast address.
They had a linux box around, but it "crashed on boot".. I checked it out and they had just turned it off one time, and it was fscking. Got that box up, tossed another nic in it and had a DHCP/NAT setup in about 15min, saved the lan party from total stupidity.
marketscore IS spyware, even tho they claim it's not.. if you google for marketscore, the first two paid links are removal tools.
One of the really bad things marketscore does is install a certificate authority so it can proxy SSL requests without the user knowing. If they connect to a bank, or worse hippa regulated systems, marketscore gets to see all the traffic un-encrypted.
I know several places are tracking and blocking their subnets whenever possible.
and digital modes like PSK can be picked up by a DSP in situations where you can't hear CW with your ears. It's fairly amazing how good some of the DSP software is these days.
I will add to another comment.. commercialization. Ham radio is not allowed to be used for business, so it will always stay a hobby, and that's one of the reasons I like doing amateur radio.
The Wedge is a psudo co-op.. it's basicaly a non-profit commercial grocery. My gf and I work at Hampden Park 6 hours a month and get a discount on food.. The Wedge (and several other co-ops) are about as much of a co-op as REI sporting goods store is.
I'm moving to CA soon.. I hope I can find something as nice as Hampden Park.
I get my dairy from a local co-op, not simply because I want to avoid the horemones and things.. (this can be had from normal stores in MN) The local farm milk is pasturized slowly, and not homogonized. It simply tastes better, the skim milk is very good, and not just white colored water.
Ham radio would be a different world if we could get packet data equipment that wasn't stuck in the 1980's. I was working on a project to put up a 802.11 based 44 net, but I could never get anyone else to help buy equipment.
GNU radio has some potential to increase what we can do with totaly under-used ham spectrum like 1.25m, 70cm, 33cm, 23cm, and the microwave bands. I'd say 70cm is the only one in that group that gets any kind of attention.
Yep.. I use a 16MB max window size on a box that does about 40mbit of averaged daily traffic. This allows me to push over 300mbit over Internet 2 from Minnesota to a test server about 4-5 states away. (sorry, I don't remember the exact location)
This is about the same as I get over the local campus backbone. When I have the window size set to the linux defaults (85k?) I get good transfers localy, but over the long distance link the latency kills the transfer rate.
I can't seem to push more than 300mbit tho, I'm still trying to figure out if it's simply a limitation of the e1000, or if I need faster than a 1ghz P3.
Yea.. two 1.5 ton units is nothing.. I have a 2.5 ton unit on my house, and it's more than enough to keep out the hot and humid we've had for the last week or so.
the DC where I keep my colo has about 25 tons of cooling, to keep up with about 40kW of systems.
(it's always good to have spare cooling capacity, especialy because you want to give the compressors a break so they arn't running 24/7)
I know people who do this kind of botnet tracing, they are looking at flow data, which is NOT the actual packets for most of their hunting.. they look for patterns in the flows, which are basicaly source/destination IP and ports, and protocols.
Although, this would be a great thing for ham radio operators, who could use the devices in bands we're allowed to.. although the legality of converting part 15 to part 97 is a concern.

I'm 27, and I started having a bit of hand pain from typing at work. I re-adusted my keyboard on my desk, raised my chair a couple inches, and the problem has mostly gone away.. having good typing posture is esential when you sit in front of a computer 8+ hours a day.
the problem with your theory is that voltage drop over say 5' of 14 gauge copper wire with 5 amps is only about.065 volts.
adjusting the gauge and strand count can probably solve most of external power supply issues with desktop computers.
The main issue I would guess is that people with desktop computers don't want the extra box, with fans. Smaller computers like the Mac Mini get away with it becaues they don't nee 300+ watts of power.
Personaly, I would love to start seeing smaller supplies, and cooler running machines.
Yes.. we use way too much energy.. right now we're releasing a lot of stored chemical energy that took a LONG time to be stored in the ground. Switching everything to nuclear power is also a short-term boost in energy usage.
If we want to sustain our energy usage rate, we will have to decrease the earth's ability to hold heat in.. if we magicaly solve the production problem some day with a fusion source.. we will still have to work at removing CO2 from the atmosphere to allow all that extra heat we pump out radiate into space.
This is a great way to script installation of windows machines. You can put any applications you want into the system and use it to push machine upgrades out.

Except the fact that most Opteron based Sun machines were designed by Newisys.
Look at these pictures:
Sun V40z
Newisys 4300
Newisys was one of the first places to design Opteron based systems.
The last 4 out of 5 bosses I've had I had a good respect for.
They either knew what they were doin technicaly, or they knew that they were there to manage, and let me get my work done.
It's not hard to find a place with decent managment.
Yes, and they also have minimum wage skills. Finding quality windows admins is more dificult than finding good *NIX admins. Neither work cheap either.

My confusion..
the 68000 was one of the early odd-ball chips, see wikipedia:
http://en.wikipedia.org/wiki/Motorola_68000
"So even though starting out as "16-bit" cpu, the 68000 instruction set describes a 32-bit architecture."
"The MC68000 had a 24-bit address, and a 16-bit data bus."
This is similar to the current Opteron, which is 64bit, but current revisions have 40bit memory addressing.

I think the amazing part is the number of Mac 128k machines you can emulate with the Treo 650..
256x more memory
40x faster clock speed (not counting 32bit vs 8bit)
5000x more storage space (2gb SD card)

Ethanol can also be used in bio-diesel production.. but afaik, it has to be anhydrous.
