For instance, my small office typically has 2 desktops and up to 3 laptops in it at any given time. Usually only up to 4 people but sometimes 5 are present. We have a network attached printer (HP LaserJet 5MP) for our printing needs. A network attached scanner could be placed next to the printer and any of the 5 users could scan. This isn't an issue if your small office only needs $50 scanner quality (just buy everyone one) but if you need the quality of a $250-$500 scanner, that's a lot of money you'd save.
Probably something that can provide incremental backups like reoback would be good (take less space, compressed). Or if you don't care for that, you could run something like Unison on the drives and actually use both of them (increasing throughput, decreasing latency) and let it figure out the discrepancies.
I thought RAID 10 required 4 drives. If you're going to the trouble to enable software RAID, I'm sure you could enable it to mount more than 2 HD's (using a USB hub to provide the necessary ports).
Well, get a USB flatbed scanner with GPL drivers and you can have a network attached scanner. Come to think of it, there are probably lots of USB devices that one could share with this box. It could even do wiring closet security monitoring with a USB webcam and a remote machine which analyzes the images for movement. The possibilities appear endless (provided working drivers can be obtained and installed on the box).
Even set up crons running file or some other method to keep the small office employees from storing their MP3 and AVI collections on the office storage device...
That depends. If you are a physicist then you assume that you are in a frictionless environment and you could push it an infinite distance. If you are an engineer then significantly less.
Try http://www.digitalearth.gov/ - yes it is funded by the US and yes it is somewhat limited in its detail but it does have a large amount of data for most of the earth.
But what if it's not your bill? I have a friend who was harrassed for months by a collection agency because they were convinced that he was someone else - the person who had the phone number previous to him. Phone numbers are aged before being recycled but all the collection agency needs to do is find a 6 month old credit account with a phone number and they'll start harrassing the new owners of that phone number. Calling all times of day and night.
No, ActiveX itself isn't the root of IE's problems. The root of IE's problems is that it is closely tied into the OS and does not run in a "sandbox" of sorts. That means that any vulnerability in IE is a vulnerability in Windows. Where ActiveX plays into this is that there are holes in many ActiveX plugins that when exploited can alter the OS. ActiveX plugins that are run in a proper sandbox (and in an application that is not part of the operating system) are no more dangerous than Firefox extensions are.
It's better than the $100 models, sure, however my $250 Garmin is just as accurate as those "survey-grade" GPS's you are talking about. My Garmin Rino 120 with WAAS support and a quad-helix antenna regularly picks up 8-10 satellites (translating to accuracy of ~2m).
However, all you need to do is plug your GPS into your laptop and record all of the data it collects. Then you can purchase/download differential GPS correction data (roughly, this indicate how far off the GPS system was at a given time in a given location) in order to calculate a post-trip accuracy of ~1cm.
The only group which (to my knowledge) has this accuracy capability in-the-field is the military.
But the problem is that the 1.5 million slashdotters are the part of the population that everyone goes to for recommendations when they are buying electronics and computers. I know that I personally have about 15-20 people who usually talk to me before they buy anything more expensive than a cheap DVD player. If each of those 1.5 million has 10 million people that ask them for recommendations then that is 11.5 million who won't buy. Each of those 10 million probably have 3 or 4 friends who tend to try to keep-up-with-the-jones so those 30 or 40 million also won't be buying one (they'll get the better X brand item). That means that somewhere around 50 million people could potentially be affected by a very bad Slashdot review.
I got a week for free in a timeshare owned by someone for whom I did a little web design. In fact, my trip to Grand Bahama Island (Freeport specifically) is only a very short while from now. I'd say that ~5 hours of web design in exchange for a week in a Freeport timeshare apartment (4 of us are going) that typically rents out for $850 is fair.
Ok, 1,367 watts per square meter (W/m2) is the average intensity of solar radiation reaching the upper atmosphere. Assuming that on average 30% of that is blocked by the atmosphere, about 1KW reaches each square meter. To avoid all the lengthy calculations, we are going to accept this premise from the department of energy (http://www.eere.energy.gov/consumerinfo/factsheet s/v138.html):
For example, a flat, horizontal surface facing true south in Topeka, Kansas (at 39 degrees North latitude), with total exposure to the sun all day throughout the year, will receive an annual average of 4.3 kilowatt-hours (kWh), or 12,969 Btu, per square meter (10.76 square feet) per day.
According to this (http://www.eere.energy.gov/consumerinfo/factsheet s/cb5.html), 1000 cubic feet of natural gas has about 1,025,000BTU. That means that 1 square meter receives about the equivalent energy of 4600 cubic feet of natural gas over the course of a year. That's enough to heat the average house for an entire month.
Even at 25% efficiency that is ~3250 BTU/day. That's enough energy to boil ~40 cups of water or power a 150 watt lightbulb for ~20 hours. Per square meter. Per day.
Is this compatible with Brook and other general-purpose GPU programming techniques? The use I see for it is this:
Imagine an openmosix cluster of dual-processor machines that run bioinformatic calculations and simulations. Lots of matrix math and such - pretty fast (and definitely a lot faster than a single researcher's machine).
Now imagine the same cluster but each machine has 2 or 4 dual-head graphics cards and each algorithm that can be created in Brook or similar is. That gives each machine up to 2 CPU's and maybe 8 GPU's that may be used for processing. The machines are clustered so a group of ~12 commodity machines (1 rack) could have 24 CPU's and 96 GPU's. Now that would be some serious computing power - and relatively cheap too (since 1-generation old dual-head cards are ~$100-$150).
By the way, does anyone know if there is any work going on to create toolkits for Octave and/or MatLab which would utilize the processing power of a GPU for matrix math or other common calculations?
How do you like the Pertronix unit? I've heard some bad things about the Ignitor II failing but I am still considering using it in my '47 Ford Flathead project (triple carb progressive, high comp heads, etc). Have you had any failures? Any other problems?
Lets see - the large RBOC's and ILEC's have convinced the FCC that UNEP should be killed. God forbid that everyone has access to the infrastructure that your tax dollar helped build.
Not exactly. UNE-P is still around. The problem with it is that the ILEC's are forced to sell service under UNE-P to CLEC's at around 65% of cost. That means for every UNE-P line they sell, it costs them more money to keep up the copper/offices than they got for the line. That leads to less desire to provide it and less quality service. If they even made a little profit (say 5%) then they would want UNE-P.
Let us compete and we will crush the inefficient, lazy, technically inept RBOC and ILECS.
Exactly - let VOIP run it's course and if the ILEC's don't adapt then so be it. That's the basis for capitalism.
Sprint, AT&T, Bell South and Verizon will all be switching voice at their cores within 7.
This is true except you seem to indicate that because they are using packet switching for voice then they are using VOIP. This is wrong - most of these companies are still staying away from IP because of COS and priority issues. Most use ATM/Sonet or something similar. Yes packet switching - no IP. Sprint is already doing so at dozens of switch sites but it certainly won't be the entire network within 7 years.
What about your valves, are they capable of handling such high combustion temperatures? You'll also need to enlarge the jets (or buy larger ones). Your ethanol fuel is a different density than gas to you'll need to re-weight your float. Also, don't forget to pick up spark plugs that are a little hotter than you use for gas. To start the car under ~70 degrees you may want to use gasoline (set up a second tank and t-valve operable from within the truck) or get a heater for the alcohol. Sounds like you've already got a prime candidate for conversion because of changes you've already made but there's more to it than just adjusting the timing and fuel mixture.
Actually, you can still get the BeTwin software (http://www.thinsoftinc.com/products_betwin_info.h tml) and all it requires is a dual-head video card or multiple cards and USB kybd, mouse and optional USB speakers. I installed and ran the demo of the software on my PC back in 2001 and I could run 2 instances of C&C Renegade (FPS) at 800x600 on a dual-head GF2 card. It worked really well for all other applications I tried. You can still download a demo of the software here: http://www.thinsoftinc.com/download_2002.php or buy a copy for ~$100. It worked great for me and I've been contemplating using it to add a terminal on my Windows machine downstairs and in the third floor rec room. My computer sits idle most of the time anyway.

Could it be hacked to run software RAID 1 or RAID 10 on the attached hard drives? That would make it more useful for small office environments.
Even set up crons running file or some other method to keep the small office employees from storing their MP3 and AVI collections on the office storage device...
How about someone installing ClamAV on this puppy? Have it auto-scan the HD every so often and keep your NAS nice and virus-clean!
Preferably the job should be outsourced to a 3rd party subcontractor of foreign origin
Ack! Now even slashdot is promoting offshoring!!! Ugh...
We already have this. It's called the UN.

> has 10 million people
That should be "has 10 people." But it sure feels like 10 million, doesn't it?
