I used it to learn how to take off. Never learned to turn well enough to get into a position where I could land, much less how to.
I find it hard to belive I'm alone. Most people I know got a few planes off the ground, and then either did something too stupid for a real pilot to try; or they got bored and walked away letting someone else turn the comptuer off.
Most thugs do not know how to hot wire a car. Any car built since sometime about 1970 has a steering wheel lock. Unless you can pick the lock (not hot wire it the car!) you cannot drive the car. Really old cars, hot wireing ment just that: one wire from the battery to the coil (the hot wire) and the car will run just fine, and you can drive away. If the car wasn't locked you can do the entire operation in a minute. With the steering wheel lock, you can't do that, either you have to pick the lock (a much harder skill to learn), or take the steering column apart (without an airbag you can do that in 20 minutes enough time to attract attention). Modern car theives either look for keys in the ignition (very common), or have a tow truck.
Nice misinformation. I don't know about military waste (other than they don't have any from the navy because the nave recycles it all), but I do know that there is a big civilian storage problem. The Minnesota governemnt often (every few years) has to expand the amount each of the two poer plants in the state are allowed to store, and each time it comes up the finial solution is said to be federal storage (yucca mountain). Lately stories have admitted that yucca mountain will not have the capacity to store all the currently existing waste, much less what is produced after it opens.
Of course civilan recycling is the answer we both agree with, and it solved the problem. (there is still waste, but it is insignificant)
Management and network design. You can only have so many hubs on a network, at most 4 between any two points (you can have more if you use a tree design, but you still can't get very many) Allowing hubs in cubes makes it that much harder to design your wiring. (With switches this isn't quite as bad as it was when I first encountered people wanting more computers in their cub than IS wired for)
Management is the next problem. Managed hubs give IS some abilities they really like, but managed hubs are more expensive. Are they willing to give up management for you?
Back feeding lines is an issue, but not as big as you might think. In nearly all cases your house is not the only one isolated, thus when you start backfeeding lines, all your neighbors think they have full grid power and start to use it, but since you don't have an unlimited supply of power, the breakers (and fuses) on your generators trip. Thus you are forced to correct the problem before you can use your own backup. That said, back feeding does happen, and it is dangerious. Dangerious enough that line workers short known dead lines before touching them so they are not a good path.
Second, in many states (Minnesota where I live for sure) the power utility must hook up any residentialy co-generation plant and use all power supplied. The amount they pay you is regulated somehow, but I'm not sure of the details. (You won't make enough to pay for a gasoline generator, but for wind, hydro or solar uses it can break even)
All the "waste" is recycleable, for more energy than the first use resulted in. The US is the only (that I'm aware of) country with a waste problem. Everyone else recylces their waste.
I question wired networks. They make sense for servers and backbones. For most users though, wires to the desktop do not make sense. Copper isn't free, and you have to pay someone to run the wires to each desktop. Hope you run enough wires too, or you will pay him to go back latter when one guy comes up with a good reason to run 3 computers in his cube. (I've known several good reasons to do this) Of course you could run more wire to each cube just in case, but then your costs have gone up a lot more.
I also question the idea of not having an office full of laptops. For a company of any size, having a laptop around means you get work done for the few moments that a meeting doesn't require your care.
Run wireless and be done with it. The speed is plenty fast if you use care in the design. (Though I agree that security needs to be addressed) Servers need the bandwidth of real wires, if your desktop needs that much bandwidth you need to re-think your application.
I don't have a source, but Minnesota grows a lot of paper trees, and the logging companyes prefer popal, which grows very quickly, lots are generally logged every 10 years or less. An Oak tree can live for 300 years, but it grows slowly. Popal grows much faster.
I find that my hosuehold is better off if I spend the vacuuming energy throwing a stick for my dog. We get some quality time, and exercise. Vacuuming just scares both the dog and cat, and ruins my hearing. (Well I wear ear protection, but I'll bet I'm one of the few that bother)
I'm not too lazy, I prefer to say I have better things to do with my limited time.
Ask your local utility if they can help. I know of a couple data centers (all on one utility so I don't if others do this, but they should) who pay a reduced rate for the power to their data center. In return on the high demand days the utility sends a command to their UPS (and in turn the generator) to switch off of mains power onto the backup. Not only do you get the benifit of lower power costs, but it tests your backup under a real situation.
Look at the power requirements of your servers, vs how much you use them. If some of your machines are a few years old you might be able to combine tasks on one new machine freeing up more space and useing less power. If you really need seperate machines, but not all the power look for low power alternatives (either mobile chipsets, or ARM based systems depending on your needs). I know of one company that replaced a bunch of old (and insecure) SUNs with a single x86 system and marveled at how much more comfortable the machine closet became.
Continue to re-evaluate everything continually. Something that doesn't work now may be good tommorow. Something best practice for good reason today may be obsolete tommorow. Sometimes the obsolete and ridiculed still gets the job done better than the fad replacements.
Hmm, I used to pay $42/month for unlimited landline, with no options. I now pay $44/month for my mobile, and I get things like callerID, and voicemail included. Sure in theory I get 1/40th the minutes to talk, but in practice I never talk that much anyway so that theory doesn't matter to me. However I like callerID, and I use voicemail, which would up the price of the old landline by $10/month. So the mobile is cheaper for practical use.
Thats before you consider the convince of having a phone that is always with you. Most of my calls happen when I'm not at home, so to get the same service I'd need the mobile anyway, plus a second phone number (automatic call forwarding exists, but a hastle not to mention the cost).
I know several people with cable or wireless internet who have dropped the landline completely, the costs just don't work out. I also know of others who have the land line phone only so they can have DSL, and they never use it, using only the mobile. I'm personaly looking for a new house, and two considerations are mobile reception, and high speed internet that doesn't involve paying for unused services.
True, but in the real world, that hardware is out there, and you might have it. Indeed because it is easy to write, and costs are critical I wouldn't be surprized if you have it, and since it works in the average case you don't realize it was broken.
Though in this particular case IIRC there was some hardware acceleration involved, so it wouldn't surprize me if the hardware was overwritting buffers while the CPU was still interupted by the packet coming in.
Until some team designs their car with a few solar panels on the back to catch the headlights from the chase van, and aims those headlights to hit that one spot. Not as much as full sun, so it isn't worth it if you are racing during the day, but if you want to go all night you can cheat a lot by generating power elsewhere, and using light to beam it at you.
Emulating printer drivers on linux wouldn't be that big a deal. I've considered it myself, all you need is a filter to ghostscript that outputs to a Windows GDI device, and then a wine type (wine doesn't deal with this level last I checked, but it would help getting there) layer to get to the printer. The ghostscript output wouldn't be easy, but if you want to cheat that, there are windows programs that read postscript that you could run through wine, and use them to print.
A lot of extra layers so it is expensive CPU wise, but CPU cycles are cheap nowadays.
My car is a tool. I do not care if I scratch it. I care that it gets me from point to point along with everything else I want to carry in it. When I go outside with one book it is no big deal to unlock the door without setting the book down. When I go outside with my hands full of stuff, I need to set something down to use my keys.
Of course I could just not lock the door. In my cheap junk car I do this because it isn't worth anything if stolen so I'm not worried about it. Even then though, sometimes I cannot open the door with my hands full depending on what I have.
I've seen machines that you could telnet into for configuration, and they would loose data. TCP ensures delivery, but it doesn't assure that the implimentation on the other end has a buffer big enough to store what is delivered. In this case, the buffer filled up, but the TCP implimentation happily continued accepting packets, and writing them to the buffer. As it was a circular buffer this ment data was lost anyway.
Worked just fine for humans, but when we tried to automate the configuration we had troubles.
Yes you can Jam GPS from the ground. However you cannot do it without announcing exactly where you jammer is. It is trivial for the military to launch a bomb at all your jammers, and solve the problem. Further, jammers have a limited range (how limited depends on power...) so by turning on a jammer you announce that there is some reason to jam that area, focusing attention on the area. You can assume some decoys, but jammers still announce something. Directional antennas are also of some use. Ground based jammers are easy to block out when you recall the real signal is coming from overhead. Combine that with sensitive recivers and you can't be sure your jammers will even jam the signal.
The military has carefully considered ground based jamming. It was done in WWII (and likely before), they are not stupid enough to overlook it. They have spent years finding things that are immune to jamming.
Because Jesus prohibited it. Doesn't matter how logical it might seem, if God comes down from on high and specificly preaches against it, you assume your logic is wrong and follow along. At least if you are a beliver (or as some would say: pretending to be a beliver).
I've put several important things on the roof and then drove off. Eventially I learned: put it on the hood, or better yet on the whindshield in front of the driver. That way when you start the car you see it and don't drive off. (you might back off, but that is slower, so it normally stays on until you want to go forward at which time you look)
Word to the wise, which will learn from my expirence. The unwise should just laugh at me and my stupidity while continuing to lose things themsevles by putting them behind the wheel or on the roof)
Gaudi got in a lot of trouble for designing and building the classics he created 100 years ago. He ignored the city planners and dared them to do something about it. Eventially his buildings became reason enough to visit some towns for their recignized beauty and sculpture. I'll bet they wouldn't let you create another one in those towns though.
In other words, I encourage everyone to ignore as much as possible building codes (but understand why they are there, Gaudi's didn't design leaky roofs, unlike Frank Loyd Wright, and they don't fall. Today they would be well insulated) to creat something nice. I could never live in a lot of townhomes I've seen because they are all exactly the same grey color, with the exactly same front, and grass - yet they keep selling.
My dad tells stop lights apart the same way, which worked great until he drove though some town out west and realized there was a light with one end lit up (doesn't matter if it was left or right), and no cars except a cop on the side of the road. Fortunatly the cop wasn't watching because he has no idea if he did the right thing.
I'm color blind, but I can see red just fine, and the "green" light is normally light blue. (this is intentional, most stoplights switched to a bluegreen a few years back to give colorblind people a clue of which is green, though I don't know if it helps for every case)
I shop at WalMart not just to save money, but because they have things. A small market that doens't have my size is useless. A small market that doesn't have something I want isn't too useful. It isn't worth my time to go to a big market for a jug of milk, but I don't just buy a jug of milk normaly, I combine my trips with other things. It only takes one thing on my list that isn't at the small market and I may as well get everything at the big market and save a little money as long as I'm going anyway. Pretty soon you are out o fthe habbit of going to the small market for anything and it is out of buisness.
However if you look closely you will notice that small markets survive because mostly they carry things that are not at the big stores. I can get a better quality of meat from the small meat market so I pay extra, and make extra trips to get there. I can't buy milk at several of the smaller markets in my town, they can't compete on price, and know that because they don't carry everything I'll be going to the big store anyway so they put things on the shelf I want that isn't in the big store.
Every try sitting in a traffic jam that didn't start until after you left? Accident that closes the entire road (sure, take the next exit, but only if everyone in front of you does so you can get to it), or just a lot of traffic? For the system to work it will need to see the future so it can tell me at 5:00 that there will be a serious accident at 5:30 that will block the road I'd normally be traveling on at 5:40 (but because of the accident wouldn't reach until 6:10), so I should take an alternate route that normally is 15 mintues longer (even though the increased traffic will make it 25 minutes longer) because it is faster based on unusual conditions that have not happened yet. Oh, and it needs to account for all the people it is telling to take the alternate. which brings up the point: why can't it tell one of those drivers that will be in the accident to take an alternate route and solve the whole problem?
In the above situation i'm thinking of an alternate that involes a major choice 1 mile from work. I can either take i94 though minneapolis, or take 694 around the city, either way, both will come togather again on the far side before I reach my house. (I also have several other alternate routes but making that choice early is the closest to a real example of an alternate route)

Like I said "that I'm aware of". Japan and France recylce their waste that I know of for sure. There are other plants I know nothing about.

I've met a couple deaf and blind people. I don't know if they can use a comptuer, but I don't see how you have managed to help them.
Met in the loosest sense, I don't know sign language. It is facenating to watch them read sign language by feeling the hand of the signer.
