My Presario 1750XL gets really hot on the bottom right below the CPU. When I first bought it, the CPU fan only came on when the unit crashed (it crashed frequently enough to produce almost adequate cooling.) I went back and forth and back and forth with Compaq, and as far as I could tell, eventually one of the bazillion patches I installed (out of 3 CDROMs full) fixed it somewhat. The fan now comes on occasionally, when the CPU is working hard, or crashed. Doesn't seem the worse for wear - the heat sink is a big chunk of aluminum, and the machine is 5 years old and has had no hadrware problems other than the battery failing prematurely.

It's been years since I've been on a plane that allowed ATC on the inflight audio system. Although in some airlines it's at the discretion of the pilot nobody does it anymore for "security" reasons.
I run a mail forwarding server for about 20,000 users. We land on att.com, worldnet.com, and occasionally cox.com's blacklist about once every three weeks. It has been impossible to get hold a human at these organization who can do anything besides recite the "send email to abuse" mantra.

There was a Nova TV special on this - http://www.pbs.org/wgbh/nova/dirtybomb/ - you don't need a fuel rod, just a few kg of medical isotopes, which you can get practically anywhere. It won't kill millions, even anyone, from the immediate effects of radiation, but it will turn a large area (Trafalgar Square, in Nova's example) into a toxic cleanup site.
As a ham, I think if we can stop this technology long enough, not forever, it will be leapfrogged by ubiquitous fixed wireless service. Then you don't have to worry about the Cable Guy climbing up on a pole and messing with 19.2 kV wiring, you don't have to worry about interference, etc.etc. The current NRPM is just to placate the utility lobbyists and their whores at the FCC.
Already, in some rural areas, there is high-quality paid service based on WiFi. http://www.dslreports.com/dosearch reports 788 wireless plans, many in rural or semi-rural areas.
Many if not most of the systems propose carrying the signal to the pole outside of the house, and then doing the last 100 feet or so via WiFi.
W Marin is great chardonnay country

Some really good chardonnays come from the S part of Sonoma and Napa that is right on the border between the Bay Area's cool climate and the really hot parts of Napa and Sonoma - the place where Domain Chandon has their huge tourist trap comes to mind.
What prevents more wine growing in W Marin is that land is even more ridiculously expensive there than in Napa - it's really fairly well within the Bay Area suburban fringe. Most think of Marin as rural but is it really suburbs all the way to the coast. (Marin does have the highest per-capita Hummer sales in the 9 county Bay Area)
The step-down transformers located on the pole outside your house would severely attenuate and thus effectively block anything above 50/60 Hz you would put into your home power wiring.
This is why X-10 type devices will work on your immediate neighbors houses, if they are connected to the same transformer as you.
I'n no mime encoding expert, would the mime encoding get re-munged slightly each time the attachment gets relayed by an infected host? (The MTA would not change it) Or does the virus itself generate the mime-encoded text?
No matter where in the world you go, BPL/PLC is trouble: The URE (Spain's ARRL equivalent) has documented interferece in Zaragoza - they have a rather pathectic web site with no functional content - one can find it by googling - but I quote the PDF document at http://www.darc.de/referate/ausland/iaru/eurocom/e uronews1103.pdf,
"About PLC, a strong movement against it has been started in Spain, led by the Union de Radioaficionados de Espana (URE). Accurate measurements done in Zaragoza have demonstrated the high level of interference (around -61 dBm), masking practically most ham signals in the 30, 20 and 15 meter bands. Consequently, the URE delegate in Zaragoza has prepared a complaint, accompanied by a detailed technical report showing the interference levels measured at several places in the city.
"This complaint -the first one in Spain- will be submitted tomorrow [ 29.10.2003 - wsanders ] to the Inspeccion de Telecomunicaciones of Zaragoza."
I'm a Ham for whom even non-PLC interference from arcing power lines is a continuing problem. I don't think the power companies, at least in my area, are sufficiently staffed to roll this out - or do you want your average-Joe cable installer messing with 19 kV transmission lines? Fortunately the technology seems to have a short lifetime; it will soon be surpassed by effective fixed wireless services; the final nail in PLC's coffin may be recent objections from the Department of Homeland Security.

Great Old Book - UNESCO Science Projects

I have this great old book of science projects for underdeveloped nations published by UNESCO in the early 60s. Things like building a dimmer by wrapping wires around two rocks and moving the rocks around in a pan of salt water. They had a great project for building an arc lamp by sawing two non-alkaline D-cells apart, salvaging the carbon rods inside, and connecting the rods to he mains. I kept blowing fuses until I got older and got to use a friend's arc welder. Works so-so with a 20-amp battery charger.
Adams radically manipulated images - the show at San Francisco MOMA a couple years ago showed before and after prints - and also how the degree of manipulation changed over his career. In general, he manupilated more as his career progressed.
I think he would have explored digital photography, provided he could have found an output medium to handle the dynamic range of his photographs.
I got a ticket on my bike and went to Traffic School with a special class for bike riders. (In most of the US you can "get out" of a ticket this way.) The teacher made us confess at the start of the class how fast we were *relly* going and at least half the class admitted (bragged?) they were tagged for going over 100, some of them in 25, 30, 35 mph speed zones. I was a mere piker at 85 in a 55.
Increasingly on EBay people are expecting "professional" quality packaging and shipping instead of a reused Amazon box from the recycling pile. I've had a few people whine about it, but I haven't had an item damaged or gotten negative feedback.
If I had to buy new shipping materials at retail for the random crap I sell on EBay, it could easily come to $10 or more for a larger item. Go to your local UPS Packaging Store (ex Mailboxes Etc - BTW why are these places invariably run by grouchy, cigarette-munching old ladies?) and check out the prices of boxes, styrofoam peanuts, etc... $$$
... WiFi. However, it was ubiquitous in most of SF Bay Area. I'd buy it again except that the little NIMBY town where I live never allowed the poletop relay units. In Mountain View and Walnut Creek, I usually got 75 to 100 kbit speeds. The poletop units are still out there, slowly being decimated by vandals and the weather.
As for 5 GHz being a wimpy spectrum, no part of the spectrum is wimpier than another, but 5GHz does suffer rain and fog attenuation.
I friend from college operates a successful rural ISP that offers WiFi service (www.htcomp.net). That works now.
How, pray tell, is this different from me going to the local marine supply, buying a $1000 cheapo marine radar, and driving around with it on my car (not that that's technically a violation of the radar's FCC station license.)
Oooh, there are PEOPLE MOVING in the VICINITY of a CELL PHONE TOWER! Call out the Black Helicopters!
You have to remember the review was form the point of view of a potential windows-killer. I think 7.3 is actually 80% of the way there. I wimped out and actually paid for a 7.3 distribution, and I was impressed how close it comes to being a reasonable windows-killer. (It comes with StarOffice 5.2 (5.3? I forget) I am a sysadmin professionally, and the last thing I want to do at home is mess with computers. So I put the "complete" RH7.3 plus SO, chkconfiged most everything off, added a couple rules to ipfilters, upgraded to Mozilla 1.2 and an hour later I had a $750, complete, 3000 Bogomip Intel and Microsoft-free windows killer. I am very happy and will probably wipe the windows laptop clean and do the same thing to it in a few weeks once I'm sure everything is migrated.
Now I have to resist the temptation to endlessly tweak the thing. I'll probably migrate to OpenOffice and gradually delete he dumptrucks full code that get instaleld with the compete dist (just how many versions of libssl get installed all over the system?!)

Yes, but it is against FAA regs for you to drop any object from an aircraft in a manner so as to damage or injure anything on the ground.
You can drop anything you want, say, if you drop it on your own private dropping-stuff test range.
I saw a demo on some gun show on cable of a rich guy in Arizona who has an old F-86 or something and his own private strafing range.
