Why would you think no one is interested? Stuff like that is exactly why I (still) come here! It's incredibly interesting, and I could spend a lifetime searching and never be lucky enough to hear from (let alone be able to reply to) someone who has this type of historical knowledge.
Some young/.er is going to remember what you said, and use that as their inspiration to save another (unrecoverable, broke, but still alive) project some time in the future that might otherwise be lost forever.
It really makes you reconsider the point at which you assume all is lost or every angle has been tried, and it proves that if you can understand the problem and adapt to it, you can do anything.
What you may find interesting is most of the noise from an engine is mechanical noise (especially from the valvetrain) not noise from the exhaust. Nearly every engine I've run on a Spintron www.spintron.com (just a customer) sounds just almost exactly like it does on the dyno but it is being motored without pistons! Granted there are some exceptions, but for most engines the bulk of the noise is still there! Certainly more than you would expect!
When we went to more advanced modeling and control strategies for our 1000+ horsepower engines, marketing wanted us to "mess up" the idle control PID to make the engine sound more like the carburated engines everyone else was used to hearing instead of taking the opportunity to redefine that segment of the market. Fortunately we knew better, and helped them write marketing literature to take advantage of the new found smoothness instead of letting them stall progress! It's still fun to say "this isn't another computer simulated 3/4 race cam you expect to sell to someone who doesn't know any better... Is it?"
Bummer you didn't have the same luck I did. 2 of them, I had completely destroyed the screens with multiple cracks in the plastic between the touch screen and LCD, both of them still worked flawlessly (long enough to get home and be replaced by insurance) I do remember having a problem with the ribbon cable to the LCD causing it to flake out, but IIRC it was an assembly problem and easily reseated.
All in all I've had pretty good luck with a fair number of them hardware-wise. I think I've had 8 different HTC phones, all of them besides the unactivatable TP's still being enjoyed by friends, or their friends as technology hand me downs to replace their broken phones. I used to have fun driving tech support crazy over buggy software to the point where I had 3 or 4 more phones than they could keep track of. ATT to Cingular to ATT and Alltel to Verizon mergers created lots of unactivatable replacement phones that were useless and forgotten. I'd just unlock them, reflash firmware and go, but the tech support people could not authorize it, so they just kept sending brand new in the box incompatible phones. Insurance sends ATT sim in a Cingular phone. Call local store and get SIM unlock code, call Cingular warranty get another phone. repeat...
I still have 7 friends using my old WinMo phones, 3 Audiovox SMTs 2 HTC/Cingular 2125, 1 HTC/Cingular 8125 and an ATT Tilt with various GSM carriers:) All lost in the shuffle from ATT to Cingular to ATT. They didn't even want them back when I tried to send them!
The CDMA phones are of similar fate, but are not as easy to reuse on Verizon. If I gave one to an existing Verizon old Alltel customer on an Alltel plan yet it worked fine with *228. Now Verizon's CS supposedly can't even do it, and all my Alltel Verizon friends are already (and still) using TPs from before the Merger because the Verizon TP2 is stripped down junk compared to the Alltel / HTC / rest_of_the_world version.
I think I only lost one stylus out of about the 20 that I've had. Later phones came with 2 though, so I'd bet lots of folks did! Any of the devices that needed them had on board storage for them, so as long as you got in the habit of always putting them back, you rarely lost them.
My HTC touch, touch diamond, touch pro and touch pro 2 had (while they did not support multi-touch) very excellent transparent resistive touch screens. They worked very well selecting and scrolling with your finger or stylus or glove or whatever you touched them with.
I was torn when switching to capacitive after using a good resistive screen, and mostly I miss it due to issues with the capacitive screen getting hosed by a single raindrop or sweat from my face, or a glove, or dirty finger. I also was excited that the capacitive screen should have less problems with nonmeaty inputs resulting in erroneous calls, but it seems to do whatever it likes far more than the resistive ones did.
EVO 4G only example of capacitive screen, YMMV of course.
Cheers
* Since its Christmas, I still have 2 brand new Alltel TP's and 2 (1 new 1 maybe lost) Alltel and maybe a Verizon TP2 laying around if anyone can put them to good use! The Alltel devices can no longer be activated on a Verizon system, and i can't guarantee you'll be able to use any of them on Alltel any more. Email me at rot13 oynpxjbbq+serrcubarngtznvy.pbz with what you wanna do with them, and I might decide you're more worthy than my junk drawer!
That's why they use 380 volts! One big splice goes to all the 12 volt stuff, then another splice comes off of that splice to do the 5 volt stuff. It is not run through regulators, it just happens automatically due to the superior characteristics of DC power! They also tap into the ground wire at various places to get the -5 and -12. Magic I tell ya!
It sees it's best efficiencies running near 100% utilization through so you want to plan your workloads accordingly, or you risk watching your $#!+ let out it's magic smoke! So all in all it should drive down the price of "the cloud" by forcing competition!
Looking into it from the bare minimum requirements and the current state of storage, and plugging a few of the numbers into Wolfram Alpha I see the problem here! While a books in LOC * Size of Google would be a better number, I took the size of the latest IBM Megadrive that is 120 petabytes and guzinta'd how many of these drives you would need just to get 2^256 bytes of storage.
8.57 *10^59 of IBM's largest drive clusters are required to store 2^256 bytes of data.
I remember when I got my sweet new K5 rig, and while setting everything up on the kitchen table my roommate came in (who knew nothing about computers, and expressed 0 prior interest to a computer before that) and asked me "so what the fuck do you do with a computer to make it worth spending that kind of money on it?"
I showed him the Internet (or What there was of it) and after about 10 minutes he seemed rather unimpressed with it. As he walked away, I said, while there is porn on there too.
Boom! He was hooked on this Internet thing. He spent the next 2 days in front of my computer. Porn site after porn site. When I came home from work on the 3rd day, he was buying a computer. Online even! Asked if it was a good one and can he get a 2nd phone line installed in the house and get his own Internet. He used both computers and dial-up connections at the same time, switching back and forth as pages loaded.
We even had the first broadband (DSL) connection in town. Completely funded by his new found love of computers.
What would it take for computational resources to store every prime number in the key space, and even the result of the multiplication or mathematicification of those numbers into a database to allow you to just look up the key and find the prime factors and problem solved.
Like a rainbow table, or lookup table instead of brute force.
How many years are we away from being able to solve the problem of factorization of a 2048 bit number (or any other hugely complicated problem) with a simple query to a massive database containing every possible answer?
Could all of Google's computing resources come close to storing this amount of data and searching it for the result faster than brute forcing it?
This will somehow suck in outside ambient air at 15 psia on the ground, or better yet! 0 psia in space? Please tell me how?
I'm really excited to learn this! perhaps you could set me up with a lmgtfy link?
And what am I objecting to?
That it doesn't appear to use anything but hydrogen and oxygen in the combustion chamber, so it would seemingly produce nearly all water vapor as the exhaust, and since it does not seem to use ambient air in the process it should not have nitrogen floating around in the combustion chamber to combine with leftover oxygen form NOX and other nasty byproducts?
Did ya miss that AC?
Can ya explain how the nasty stuff from the outside ambient air gets in the combustion chamber to react when it's at 1350 psia and contaminate the normally clean (hey I thought that made water) hydrogen oxygen combustion process?
Extra bonus if you explain, or Google link is fine, how outside ambient air gets in a rocket engine while in space!
Because that's what we're taking about here...
If you had a UID I might consider discussing your super sucky flame theory some more, but since you troll as AC....

APK if you're out there... Please add this jerkoff to your hosts file!
Not fun... For some... The bigger the challenge, the more fun it is because I have to really understand what's involved. I get to learn new ways to use math, and look at problems from multiple angles when breaking it down to the assembly level. Especially when dealing with limited hardware resources, and instruction sets!
It's also more rewarding to see it get completed as well.
Knowing how to multiply two 32 bit values when can only add and shift two 8 bit values should be something every self proclaimed computer geek should know, and be able to optimize!
And for someone in love with DRM, allowing a mobile USB hard drive to show up as a mobile USB hard drive and thus work on anything that can read a mobile USB hard drive would not seem like a good way to gain compatibility!

+2 on that!
More room to embellish them with blinggetty-bling and to incorporate those needless buttons as well!
Fake crystal home button anyone? Or perhaps a heavily embellished house-shaped 3D home button?
Finally... I think if you call it Phat and embellished you can take that up +3 TDF (Tablet Domination Factor) no matter what OS!

So where does this outside ambient air come from while in space?
Looking at:
pw.utc.com/products/pwr/propulsion_solutions/j-2x.asp.
I see:
Pressure-Combustion Chamber: 1,380 psia
This will somehow suck in outside ambient air at 15 psia on the ground, or better yet! 0 psia in space? Please tell me how?

So they don't just mix the hydrogen and oxygen in the combustion chamber and light the bitch? They somehow force outside ambient air in there too?
Spring break as a teenager kinda sticks out in my mind...
