The short story: Orbital distance from a body (say the earth) is a function of speed; the further out something orbits the faster it's moving. To raise the orbit of Hubble (which is currently in a relatively low orbit) out to the moon (which is fairly far out there) would require Hubble be accelerated to a faster speed... the difference in speed needed is called delta-V. I don't know what the delta-V would be, but I can guarantee you it's more than the small reaction jets on the hubble can generate.
I think if you google on "Hohlman Transfer Orbits" you'll find more info than you'd ever want on the subject.
Though I'd think they could purge the tanks and drop all of the consumables to loose a lot of mass, and the reaction wheel assemblies I believe are on the bottom edge where they could be quickly detached in orbit and ditched.
The hubble is powerful enough it could probably even see you hiding under your bridge waiting to catch innocent newbies passing about your wee little head.
Different protocol, different ports... Have the first server from the user append a count of how many emails this user has sent this hour.
On the mail client side if the "hourly volume count" of the sender is too high, flush! Out it goes.
Yeah, AOL etc won't switch... but I could check the "old mail system" once a week without a problem. But mail from the geekier friends would be quick, clean and spam-free.
Don't forget that there are drivetrain losses through friction and viscous couplings... that's got to be a few percentage points there too.
And finally slowing the car down by hitting the brakes wastes all of the kinetic energy as waste through the brake pads.
I think some city was experimenting with adding storage flywheels to their buses. Energy normally dissipated through braking would instead go into spinning up a large flywheel, and once the bus started forward again the flywheel energy would help the engine accelerate the vehicle. Seems mighty dangerous though... there'd be a lot of energy in the flywheel that would be unleashed if somebody crashed into the bus.
If you have automated test scripts running 96 hours testing a piece of hardware and they detect very intermittent glitches you could spend *days* tracking it down... only to find that your hardware is fine. Nope, rather your router decides once in a blue packet to revector things to a net that doesn't exist (the test lab is off the public Internet).
It's cheaper for me to junk however many Belkin pieces I have and replace them with Linksys or D-Link rather than risk blowing hours upon hours of test time and engineer time because some marketing droid decided that every HTTP request comes from a set of eyeballs.
Any problem that has the potential to waste days of my time (and my test teams time) isn't an unstory... it's got far bigger personal impact to me than all the SCO-IBM stories.
But the lawyers went ape shit over it. You'll notice that the Windows SDKs and DDKs specifically mention that you'll not use them to develop drivers that can run on other operating systems.
Plus as we learned on OS/2 with the Win32s emulation, Microsoft will rev the spec once a month to keep the emulation broken.
OK I agree that the whole RNAV complex is potentially susecptable to RF interference.
However if your gyro instruments depend upon a computer or the autopilot then you shouldn't be flying in IMC with it because you then have a single point of failure for your DG or AH...
If your electrical power goes out in IMC do you really want to be using the turn indicator and the whiskey compass to get yourself out of it?
Now hold on a second... You're saying a cellphone affected your Gyro??? And please tell us how an RF signal affected the physics of a spinning vacuum or electric-motor gyro?
MS uses a layered crypto scheme... 1. At CPU reset a hidden ROM image inside the chipset decrypts the main BIOS flash image. This is the key Bunnie found. 2. The BIOS image then decompresses and decrypts the extended BIOS image using a key different from the one used in step 1. 3. This extended BIOS then loads the kernel from disk and validates it using yet another different key. 4. The kernel then uses yet another key to validate the games loaded off DVD-ROM. This would be the key everybody is after.
As a twice-former employee of said horizontally shredded firm (I quit once and later got laid off) I feel your pain. I quit when I was passed over for a band change for 2 years in a row. After 2.5 years with "Steven & the Interns"'s company I returned to Company-of-the-Acronym-that-must-not-be-named maxing out a position 2 bands higher. 4 months later, review time. My new boss managed to give me a 5% raise. Whoo! The following year I got another 5% raise and talk of my future promotion to Senior. Whoo^2! Then 2 months later everyone in Beaverton got laid off.
At least my severance package was based on that awesome salary I was making for 2 months!
Also most people conceive of "things" as being physical tangible material. There people have absolutely zero experience with the concept of intellectual property.
So the 12-year old coming home with a stolen CD... a tangible physical object that deprives the store of their product is clearly understood as stealing. Virtual bits that flow into their apartment over the phone line don't have any corpreal heft and as such the Torres' probably assume it's all like TV shows and radio which again float into their house for free.
Yes true and all, except this guy has deliberately made himself *VERY* *VERY* high profile.
For him to pirate now is like slamming on your brakes screeching to a stop next to a cop car, flipping him the bird and then peeling out down the street in a Hazard Yellow Ferrari. You ain't going to blend into the background...
Because business is no measure of success or failure for a culture. The Sequent folks had more respect for each other and treated each other better than any other company I've been at. They volunteered in the community together, they participated in after-work sports events together, and they have the best alumni networking I've seen.
There are many reasons for the failure of the business, but none of them had to do with the people working there.
No... Sequent the business might have been doomed (due more perhaps to executives and their race car habits than technology), but Sequent the culture was a success.
And to the best of my knowledge IBM isn't selling any legacy Sequent NUMA-Q servers which are the only machines capable of running Dynix/ptx.
In other words this announcement really means so so little. It's like CP/M announcing they're revocing MS-DOS's ability to duplicate their INT interfaces...

This post as a +4 or +5? Y'all are hitting the crack pipe too hard.

It'd be great if they could bring it home in the Shuttle and put it in the Smithsonian... I'm certain the museum would hang it from the ceiling!

He has a great deal of info about how reversable computers work and why they save energy.

Not quite... BCRVM1 was the old IBM Boca Raton mainframe. BCR=Boca Raton, birthplace of the IBM PC and OS/2.

RAROSE AT BCRVM1
I wonder if he's got the same old email address:
DRDAVE AT BCRVM1
Matter of fact, I wonder if dear old BCRVM1 even still exists anymore.
Too bad the fix is just a software upgrade... seems like they could add a retractable "nose wheel" that would deploy on low battery situations.
I mean really... who wants to land their Segway in a full stall anyway?
