Often your community college or school district will offer vechicle maint adult ed courses. These are beginner courses and are usualy a lit bit hands on. Vehicle maint is probably not real easy to learn via the web.
I guess next time you'll use a little bit of that $438 K grant to keep multiple backup. and make sure the tech is trained on your system. Actualy the more I think about it the high my hookey meter goes up. Didn't your sys admin keep an eye on the guy while here was working on his baby, or did everybody in IT with any real brains jump ship all at once, leaving only a newbee's to try and cope.
Try keeping sensitive data on a linux machine and use Samba to make it available to the windozers over the LAN. Everything is in one place for easy backup.
Eventualy somebody is going to click ok instead of cancel and wipe out the OS with some buggy windows program. but at least the data will be safe. Then you can load the dos 5.0/ dos 6.62upgrade then windows 3.10 then windows 95 upgrade then windows 98 upgrade then windows ME upgrade ect... while the boss screams "don't lose my data!"
155-170 mph limit is probably because of the speed rating of the tires, they'll over heat and blow out if over-sped too much,or even just seperate from centrifical force. If you really want to get insanely stupid, just get racing tires and a new speedometer gear. Get one that has 1.61 times as many teeth as the one in there, the 'puter thinks its going 270 KPH, but you'll know your going 270 MPH! Of course it's unlikely a street car would actual go that fast, big differnace between 120 mph and 170 MPH.
While travelling from Graffenwhor to Messau I almost became intimate with a farm tractor pulling a manure trailer one night on the autobahn. I was real glad the army van would only go 80MPH instead of 120 MPH or the van would have hit the shit.
Nitrous Oxide is indeed used, its sprayed into the intake as a fog with a lot of fuel. firstly it cools the intake gasses as it evaporate into gas, when it get compression heated to a certain temp it breaks down into n2 and o2 gasses endothermical greatly reducing ping/predetonation, lastly it releases a lot of oxygen. If the extra fuel stops something else will burn like your engine instead.
Nitro Methane is a fuel,called nitro or fuel, and is used in things from engines for RC cars and plane, go-carts and some drag racing engines. (it's also used in explosives, that's why McVey wanted it) Nitro has a distintive smell when its burnt and burns slow allowing engines to have a lot of compression and boost to make mega-power. Nitro is corrosive to metal and a lot of plastics so its useage is labor intensive in engine applications.
There is no skill on going from one end of a line, to the other.
Ever try dumping a clutch and and stomping a throtle at the exact moment to precisely cross the starting line as the light turns green; Professional reaction times are running arround 0.04 seconds. How about keeping a cars straight while the tires are spinning, and increasing in diameter in unequal amounts. Not to mention the torque from an engine putting out at least 2500 hp tring to twist the cars frame into a pretzel. No all motorsports require tons skill, just because you don't understand doesn't mean it isn't there. That would be like saying F1 or NASCAR is easier than top fuel drag racing because in them if you blow a shift or a turn you have the rest of the race to make it up
a battle of programmers rather than drivers. Sorry but for racing today, it's a team approach. Each team is a highly integrate and optimised system of mechanical, electronic and human systems.

Can anyone enlighten me about the value produced by Einstein's research? well lets see Einstien basical invented Quantum Mechanics which lead to tranistors, which lead to Integrated circuits, which lead to computers, and Microsoft is worth what about 11 Billion dollars.
adding in all of the branches between Einstien and Gates and you'd come up with just about everything we think of as having value.
Don"t all the wires connecting the chip to the pins in the case also contribute to it's heat dissapation? How about putting a little bit of methanol inside the chip carrier to move the heat out to the carrier cover?
bringing less warmth to your extremeties. which also means less heat loss through your extremities; your hands and feet will get colder but you get less degradation of your core temperature. Put on gloves, a hat and drink hot coffee instead of soda and you'll be fine.
a comet would bring a lot of water especialy if there were several We tend to think of water as primarily as a liquid, but its also a solid as ice and a gas as steam. The initial impact would make a good sized crater and a lot of steam which is also atmosphere. Sooner or later the steam condenses into liquid water and freezes into ice. Ice moves just like water just slower look to terestrial glaciers for an example, and its easily capable of carving large vallys. Ice also sublimates, that's why your ice evaporate in the freezer and water on Mars eventualy escapes into the atmosphere, is broken by ultraviolet into lighter hydrogen and oxygen and escapes into space.

IDE RAID Examined
·
· Score: 2
I don't quite understand where this Inexpensive crap came from.
I though RAID was developed back when a pc's hard drive was called a winchester, and it floppies were 8 inches. Professional hard drives were the size of a washing machine and had removable disk packs.
At that time anything less than $50K for reliable mass online storage was inexpensive.
I've been thinking seriously about going RAID 5 on my machine, not because of performance issues but for reliability issues; my IDE drive just took a puke. I'm sure that RAID is going to reduce performance, but then again I'm not trying to render 3D movies either.
I'm not sure I'd put a lot of faith in the benchmark either, when IDE100 drive beats a IDE133 drive the hookey-meter moves up a few notched. IDE raid is still a young technology, a cd burner or even a drive dedicated for back-ups and consistent back-up plan may offer a lot more bang for the buck.
It takes some really major changes to neccessate upgrading distro versions. My machine is running SuSE 7.1 which is really old, I just install patches, some come from the SuSE site some come from Redhat some are for SuSE 7.1 some are for SuSE 8.1 nothing seems to have broke yet. Of course your millage will vary.
As the LSB comes on line better, my behaviour will become more common.
I have to agree with you and even extend the thought. How many companies really have enough experience with Linux in areas other than web serving to even make a wild hairy-assed guess about admin costs over five years?
How about system recovery? eventualy every peice of hardware is going to take a puke. How hard is Win2K or Linux going to be to recover, have enough actualy crashed to even estimate?
My guess is that as Linux penetrates further into the data center, and there is more experience top-to-bottom in the IT staff that Linux's cost will drop further than Win2K's will because linux will self-administer easier.
what creeped me out was when H/D sued Honda for unfair trade practices in the dirt bike market.
The best thing about H/D is the sound, two cylinder firing 90 degrees apart, just like the old John Deere 2 cylinder tractors which also have a fanatical following
not to mention that those big squire-cage fans would have a lot of sharp radar refleecting angles and their rotaional speed would just SCREAM on a doppler radar.
I do think this would make cool model airplanes, but I suspect the concept will not scale very well.

"First, in the absence of an atmosphere, blast disappears completely."
I don't completely agree with that, the mass of the actual device will produce some blast, the point is most of what we think of as an nuclear explosion is caused by the radiation heating the gas we call air.
Break the rock and you get caught is a hailstorm of gravel. one 500 pound piece of gravel at 15,000 MPH will hit like a 15KT nuke. We shouldn't be worried about residual radiation in space, most fallout is caused by neutron induced radioactive material and if we have to detonate that close to earth we fsck'ed anyways.
Oh by the way my original post the explosive should have read 10-14 hundred thousand pounds, not million.
This doesn't correspond to detonations on Earth

Stopping Killer Asteroids

5 to 7 KT does this...crater diameter of 408 m depth of 100 m nuclear detonations produce disapointing crater, rest assured that 10 to 14 million pounds of TNT would have made a much larger hole in the dirt.
The reason for this is when an nuclear device is detonated, the primary effect is a burst of Gamma radiation. Air absorbs the gamma, and re-radiates X-rays a little cooler until eventualy the radiation drops in color to infra-red. The distance from the center to when the black-body color temp drops to infra-red is called the fireball.
Dirt or astroid is much more opaque so the results are less. In space there is no air to speak of so what you'd have to do is detonate a ways off the surface so an area is irradiated with gamma, heats up and vaporizes a way giving a push from the mass of the vapors expelled by the astroid. This method might be best if the astroid is heading at us and has a high closing velocity, because time would be short.
If the astroid was coming from "behind" and closing slower, a reactor powering an engine place on the surface would be much more do able. It would be cool in such a case to place it in a parking orbit, hollow it out and make one whooper of a space-station out of it.
I've had a fantasy of catching an iron-nickle astroid, heating it up with a parabolic reflector and sunlight and inflating it like a glass-blower would.
I looked twice and it didn't see where it said he didn't get paid, it did say that the ex-boss was rude and unprofessional.
I would guess that that also meant that; 1. his time was of little or no value to her because firstly because he's been un-employed for five months, and secondly because he jumped when she jerked his chain. 2. expertise don't count either because he got that on the job and she already paid for it.
Personaly the next time the lan crashed, I'd estimate the time to fix it as if you've never seen it before, charge that way, then charge for the convienence of knowing the system well enough to fix it faster than any other LAN monkeies out there, then add a premium to it for past rudeness.
