> The Army expects by September to spent about $7.5 million on the program
With all due respect,
Advertising is very expensive.
I mean, Geez - $7.5 Million would buy what?... two or three superbowl slots? For a little perspective, With the population of the United States at around 300 Million, This works out to about 2 1/2 cents per citizen. IMHO, a worthwhile investment to recruit reliable people to operate Multimillion dollar equipment like an
$8.1 Million Cargo Plane. or billion dollar aircraft carrier. Do you want the best people you can find? Or do you want to have people that weren't even accepted into college?
Also, Consider the cost to exposure_time ratio.
Instead of viewing a 30 second commercial, potential canidates will likely be spending HOURS and HOURS of time on their computers. I don't know about you, but I don't usually decide my future upon a 30 second commercial (Although I love the one with the Godsmack tune;-)
It is a well known fact that the military has been having difficulty recruiting people in recent years. They're doing all they can to fill the empty spots, and they're being very creative about it. Heck, It looks like they're even teaming up with VH1 to start a show called Miltary Diaries (or something like that).
The point here is to create a little bit of excitement about joining the military. If you get enough people talking about it, many will start asking questions and talk with their recruiter. Yes, The military still wants Athleticly gifted recruits, but the new military is evolving into a thinking man's war - Not the brute force approach we've come to expect from some 3rd world country.
Lastly, Don't make this a political issue.
(off the Record, I did not vote for Clinton or Bush. )
Your $100 Billion dollar deficit figures are misleading. What makes you think that republicans spend more money than democratcs would have? You convieniently neglected to mention President Clinton's $288 Billion Military Spending. " Yes, Virginia! - Democrats like to spend money too! - And this was well before Buzzwords like Terrorism and economic recession gained recent popularity. Give these guys some credit. I think it is an excellent tool to increase recruiting numbers in an overweight slacker society - Although we may need to wait a few years and see the numbers to see who wins this argument.
Sure is gonna be tough to outrun a big balloon eh? </Canadian Accent > Won't drug runners and terrorists just look up in the sky and decide to take another route?
> Organizational hierarchies of data sources are arranged so that an infinite number of sales presentation configurations can be created (emphasis mine)
It looks like a very ambiguous patent to me, but the word infinite stood out as I read it. Is it truely possible to obtain infinite configurations? Surely there are very many, but infinitely many? Can you prove that your website does not provide infinite configurations? (maybe your site only provides 256^1293923836238348 configurations) IANAL, but it seems like a possible argument.
To do it, I purchased a used HP scanner with a 50 page Automatic Document Feeder (Search for ADF on Ebay).
I started with the easiest books. - Books that could be removed from the binding. Scans go smoothly with the ADF, but it is not as easy as you might think. I find that I spend most of my time naming the files because the default naming comvention is *01.jpg , *02.jpg , *03.jpg, etc.
It is a problem for two reasons:
most of my books are double sided. My HP scanning software for windows does not let me name files with a 2,4,6,8 or 1,3,5,7 format.
If books contain more pages than the ADF holds, The first page scanned will still be named page 1.
If I knew a little perl, I'd write a script to rename the files between scan batches.
For scanning full bound textbooks, there are two main problems:
Scanning the side of the page along the binding requires carefully holding downward pressure on the book to keep it near the scanner glass.
You cannot scan the book using ADF, so you should expect to spend A LOT of time scanning.
Do not even consider manual scanning hundreds of pages with a parallel port scanner. WAY WAY too slow. USB scanners are cheap now, and will usually scan as fast as the scanner mechanism can move (assuming black & White scans).
Lastly, be realistic. Know how much time you'll need to invest. Rule of thumb: If you need to scan manually, expect to scan about 200 pages per hour at top speed. Is it worth investing six hours to scan that 1200 page book of yours? If money allows, I'd suggest purchasing a second book that you can afford to destroy. Cut the binding off with something like a jigsaw, then insert the pages into an ADF scanner. Hope this helps somebody.
This has been around for a while for the treatment of attention deficit disorder. However, for A.D.D. patients, the goal is to focus better instead of relaxing. Still a very cool treatment if ya ask me.

> There is no distro or UI (KDE/GNOME) which comes even remotely close to being user friendly as OS X or XP define it.
I can't speak for OS X, but I don't know how you can say that Windows XP is windows friendly! I'm not a computer genius, but I've had so many problems That I've reformatted my hard drive and "downgraded" back to Win2k. I couldn't even ghost my XP partition because apparently XP fucked with the partition table!
other noteworthy things I hated about XP:
No fast way to find files Back in Windows 9x & 2K, with 3 keystrokes I could easily click the Start Button, (F)ind (F)iles, and the find dialog would pop up. Now I need to slow down and grab my mouse, click a few times, and then move back to the keyboard. Nitpicking? Probably, but I don't like it in XP.
Networking Yes, there are some cool pictures to help you figure out what kind of network stuff you need, but for Christ's Sake, QUIT MAKING decisions for me! NO, I DON'T want my network cards briged!
Quit asking me to sign up for the god-damned Microsoft network!!!
Yes, there are some new cool features in XP, but I should have listened to the old saying, If it ain't broke, don't fix it.
> You basically only need a special computer if you are running massive cams (alternatively you could just raise the idle, which most people do)
As an ex-ford mechanic, I can tell you this isn't a good idea. Sure, you can adjust the idle position of the throttle body, but the problem is, you'll also be changing the voltage value of the throttle position sensor. If my memory is right, anything above 0.9 volts on a ford signals that the engine is "off idle" and the EEC module will then leave "idle mode". If you adjust the idle position throttle stop, you should also elongate the mounting holes on your TP sensor so you can adjust it to stay below the correct idle voltage. IMHO, a better way to boost idle speed is to add a IAC bypass plate. It's basically a 1/4 inch thick plate that bolts betwen the Idle Air Bypass Valve and the throttle body. There's a small passage with an adjustment screw that lets you increase airflow without changing the idle TPS voltage.
I also have to disagree with your statement that most cars don't benefit from performance computers. Any gas engined car would have better performance with more advanced timing. Is it risky? Yes. If your peak cylinder pressure occurs before Top Dead Center, you'll be lucky if you only blow a head gasket.
Engines are tuned with a 3-way comprimise between Power, Emissions/Fuel Economy, and Drivability. It's a difficult balance to achieve from the factory, and if you don't care about drivability or emmissions, it is not difficult to boost your power. My toy is an 88 Ranger with an 89 Mustang 5.0 engine & Stock mustang EEC module. I'm running 13's with few mods and without my nitrous but I know It would be even faster if I could tweak the ignition timing and fuel map. Would I have to spend a lot of time? Yup? Worth the effort? Probably not - unless I'm just doing it for fun.
> This won't solve our energy problems. It will help some though. It is only worth putting tidal plants in areas with large differences between high and low tide
The high tide and low tide height difference is trivial. Just to be absurd, let's assume the height difference is 10 meters. So that's potentially 10 meters of travel from low tide to high tide. Problem is, How much time does it take to move from high tide to low tide? We're talking about literally hours.
So lets look back in our physics book. 1 watt = 1 Newton * 1 Meter per second. To keep math simple, lets assume that our energy capturing device relies on moving a column of water weighing 10,000 Kg. - converted to force, we have roughly 100,000 Newtons. Also to keep math simple, lets assume the tide moves once every 10 hours (I honestly don't know what's accurate). 10 hours equals 60*60*10 or 36000 seconds. Our power output is now:
100,000 Newtons * 10 Meters / 36,000 seconds = ~27.8 Watts or roughly the amount of power required to power a high efficientcy bulb. note that this is assuming 100% efficientcy!
IMHO, 27 watts is negligible considering such a huge column of water being moved.
Now lets look at the energy of each individual wave. To keep math simple, lets assume a moving column of water weighing only 10 Kg. (converts to roughly 100 Newtons of Force). Assume a wave height (amplitude) of only 1 meter. And lets assume a wave travels past every 10 seconds. Now we have:
100 newtons * 1 meter / 5 seconds = 20 watts. That's roughly the same power output with only 10 Kilograms of water moving! Assuming we could extract the energy with 100% efficiency, were talking about a factor of 1000:1
Please note, I'm only nitpicking. (you could easily nitpick my crude math). I agree that Nuclear energy is underrated, but I felt that this technology should also be defended.
It was not mentioned in the article, but somebody needs to decide what exactly is considered child pornography. In other words, after sifting through thousands and thousands of pornographic images, you may not find ANY child pornography. How do you really know if a person in a photo is 18 or even 17? It could potentially take weeks of endless staring at a computer screen to find ANY illegal porn. For the record, I am totally against child pornography, but if our government needs me to stare at porn all day long, I'll do my best to serve my country well.

Moderators without a sense of humor: Go Ahead - make my day
I'd like to see a Wallet-sized rescue disk CD in the next boxed distro. Not sure how much cost it will add to the distro, but it seems like it would be inexpensive.
Yes, I know of several root/boot rescue disks, but a disk made specifically for Mandrake might be more useful & user friendly.
Floppies are unreliable, slow, and don't hold much.
Include something like Symmantec Ghost for easy backups
Include CDRW support and USB2/firewire support for those new external burners and hard-drives.

Whoa man! looks like both of you guys should be yanking your old Heat Transfer, Accoustics, & Fluids books off the shelf and plan on doing a little review.
I can debunk almost all of (both of) your claims. Firstly, you both argue about the significance of Airflow around the hub. BFD. Airflow is not everything!! Heat Transfer is everything.
There are 3 types of Heat transfer.
Radiative heat transfer: this is what makes your black colored car much hotter than the surrounding summer breeze. In this case it is insignificant compared to Conduction & Convection. (therefore it wouldn't matter if your fan was white or black)
Conduction heat transfer This is the movement of heat from within ONE Material. In other words, put just an edge of your frying pan on the stove and the rest of the pan will eventually get hot. The main application of Conduction heat transfer occurs within the heat sink.
Convection heat transfer This is the movement of heat between 2 materials. Convection occurs between the processor & Heatsink, Conduction then moves the heat to the other side of the heatsink, and then Convection transfers heat from the fins of the heatsink to the air. Sound simple? It's not.
Since There is a heatsink that acts as a buffer to the heat transfer, I argue that the 2nd A.C.'s claim is misleading. Yes, if we mounted a fan directly to the processor it would likely help to aim airflow at the center. In that case it might be nice to have a hub-less fan. Since only fools would run without a heatsink, it doesn't really matter much.
Remember our lesson on Conduction and Convection? Well in our case, conduction moves heat away from the core (the center) and does it much more efficiently than convection. One reason for this is related to Fluids.
In fluids you learned that as a fluid (in our case Air is the fluid) moves around an object, a boundary layer occurs. For Maximum Heat transfer, This is a Bad Thing. We want to introduce a "micro turbulence" that will break up the boundary layer. The great engineering problem to solve is to find the best comprimise between airflow, turbulence, and noise.
So what's the best solution? I doubt that there is a single solution for all computer users, but here is what I like:
It's a circuit that will Automatically adjust the speed of your fan to maintain an appropirate temperature. Unlike adding a Rheostat, it doesn't create a larger current draw, and you don't have to continually adjust it.
For those of you that would like to learn more about heatsink/fan benchmarks check out this site: http://www.dansdata.com/coolercomp.htm
A buddy of mine bought one of those "biometric" things. It's basically a USB fingerprint scanner, but to my knowledge it only works with Windows XP at the moment.
It's very easy. If you want to login you just put your finger on the scanner and the computer does the rest. If you like having muliple accounts, no problem. Use one finger for your superuser account, and another finger for your main account. Unless you belong to a circus, I imagine that you could have 10 accounts per person.
Another feature it has is the ability to encrypt individual files. As far as I can tell, it acts like winzip.
So why don't I have one? They're still a little pricey. about $70.00 It's a "gee whiz" coolness factor now, but until they drop down to about $30.00 and offer linux support, I won't bother.
Microsoft wants me to "upgrade" to their new filesystem.

It's a circuit that will Automatically

The obvious solution would be to replace all gages with idiot lights and fuzzy dice.

REAL MEN [tm] eat cats.
They gut 'em with only their fingernails,
poke them with sticks,
and cook them over an open fire they made
by rubbing a pair of matches together.
None of those wimpy Frying Pans for these men.

IANAL, but I'll bet some crazy lawyer would classify it as an assult rifle. I'd do it myself just to piss off Rosie O'Donnell.
