Some people refer to pro's and amateurs by whether or not they make money doing what they do. I define it by whether or not they produce great works, or pieces of shit.
People who create websites based only for IE are amateurs. Although IE may in fact be the dominant browser, the simple fact that you didn't take the time to make your tree-views or your java applet run in a few browsers (isn't that the point of java, platform and browser independence?) shows just how committed you are to quality engineering.
Those people who outright reject non-IE browsers by putting up a warning sign, rather than broken HTML/javascript, those people I respect. They know that they've created something that only IE can use, but they go out of their way to ensure that you don't get shit interfaces.
In C++ floats have precision issues if you go more than 8 or 9 decimal places. doubles are the preferred means of computing highly precise decimal data.
However, for an accounting app, I don't think this particular float precision issue is going to prove to be one.
Windows, Linux, and many Unixes do indeed support TLS, but the heap is global to the entire process. What I'm thinking about, is a thread heap, such that each thread has it's own protected memory heap that cannot be tread upon by other threads (by far the #1 cause of memory screw-ups for my programs).
The benefit to having a thread heap is that by killing the thread, the OS can safely kill handles owned by that thread, files, heaps, sockets, devices, etc. Currently, it's too hard to safely kill a thread.
I have to contend that reliance on the Russians, while not a bad thing in and of itself, has hamstrung our space efforts. Had we not had the Soyuz available as an escape vehicle, GWB wouldn't have been able to kill the X38 Crew Rescue Vehicle, which, BTW, could have been modified to serve as a Crew Transfer Vehicle when bolted to the top of an Atlas or Delta rocket.
While I was sorry to see the X33 killed, I can't say I blame the Administration. The X38, though?
Actually, it's not. Since the Earth is tilted 23.5 in respect to the sun, a 23.5 degree orbital inclination is better. An inclination equal to the moon orbit's (28.5 deg on the average) is even better for translunar injection.

The $100 billion dollar number includes things like Shuttle launches, mission control, radio rental/amortization for telemetry and communication and all the other great operating costs. The $26billion amount only covers actual materials cost to build the station.
1) Why not have, say, 100, or 1000 registers on a chip?
Transistor space. I don't know about you, but I only have about 100 sq inches of space in my 19" racks for a motherboard. Can't make CPU's much bigger than that.
2) What's the brightest, in theory, in terms of reflectivity - silvery chrome (like a mirror) or white? There was a thing on Slashdot a few months back about JPL Black - is there a white equivalent?
Hmmm... good question. Are we talking theoretical pure white, or real live white stuff, like sugar? Having worked with lots of white powders in my day (plastics precursors), I'd have to go with silvery chrome. I've never been blinded by the sun glinting off a pile of sugar, but I sure have when it glinted off the bumper of my '84 Buick tank.
Linux was barely runnable in 93 or so. 95, 96 I can believe, but 93? Got a CVS tree to back that up? I'm genuinely curious, not trying to start a war...
If you've ever read some of the history of U.S. submarine intelligence, you'll discover some great stuff like the Soviet cable taps that took place for nearly a decade, until some rat at the CIA sold out the fact for a mere $2million.
So we can deny other countries that same benefit? Peace through strength? Because the ultimate strength is a nuclear weapon. The ultimate deterrent. Who are we to prevent people from acquiring it?
Who's to say this research doesn't lead to hybrid scramjet/rocket motors? Then where exactly is the wasted weight? A scramjet is much closer to a rocket than a turbofan, the potential engineering challenges facing designers could be less than we expect. Hence the need for experimentation. Anything that has potential to let us drop 1/4-1/3 of our launch weight per payload is worth exploring.
For aircraft which that we know something about their respective operating regimes, that's pretty much how it goes. After shitloads of wind-tunnel and engine-bench testing, you put all the pieces together and run the aircraft up the runway and off into the sky.
Here, though, we know almost nothing about the hypersonic engine operating regime, hench the need to the type of testing the X43 is designed so.
Robots, my friend, have much finer motor control than an astronaut sweating in a mylar suit fighting against the air pressure that's keeping him alive to move his fingers encased in giant gloves. Sorry. Any robot that NASA could buy from a deep sea operations company and put in orbit will have much better motor control than any astronaut.
The tool capabilities, the intelligence, the ability to fix themselves if things go wrong, much harder to put in a robot.
But since LEO is only a fraction of a light second away, communication isn't the problem that it is with Spirit and Opportunity.
When the U.S. government needed money to continue fighting that REAL boondoggle called the Vietnam Conflict, and took away all the money to build the shuttle the way the engineers wanted to build it. 2 stage reusable rocket, no insulation tiles, no SRB's, flyback booster, and no crazy requirement for 1000 mile crossrange that required a huge-ass wing surface to give it nasty reentry characteristics.
That's when.
Notice how much the current SLI proposals all look like the first shuttle designs, before NASA lost all it's shuttle budget money.
Not completely out of control. It's not like an airplane flying at full throttle with all it's control surfaces giving random inputs. It's going in a straight line at a known speed being acted upon by a known force pulling it to the center of the earth causing it to go in a circle around our planet. It will continue to do so, until it hits enough atmosphere that it cannot sustain said forward travel, and dies a fiery death.
But your point about robotic on-orbit vehicles is dead on. If Columbia had a small basketball sized robot that she could have programmed to laser-inspect the entire hull from the moment they opened the cargo-bay doors, they might have had a clue before they died (not that this would have necessarily been a good thing, but they could at least have said goodbye).
Technically not true. A Soyux+Progress mission could allow the hubble to be upgraded on-orbit. Such a mission would have severe limitations as to what could be replaced (size/weight limits of progress carrier) as well as duration (on-orbit capabilities of the Soyuz module).
Um, cuz with no IP laws, microsoft code wouldn't stay "secret" for very long as every developer in the place walked out with DVD's filled with code and build scripts and put them on the net.

Oh God, the market-speak got me! Must be too much time listening to my crazy officemate talk about his blues band...
Must go purify my soul with some Counterstrike now.

Then that is what we call a hybrid solid/liquid rocket motor, and not a solid rocket motor, right?

And I thought that was because the tricks they use to get 16 bit code to run alongside 32 bit code just are not supported in x86-64?

Right around the same time Bill Cliton turned "It was only a blowjob" into a non-sexual encounter.
Ah, but there are at least 8 countries out there who possess the hole card... Thermonuclear weapons.
No robot army, no politician survives a 500kt direct hit.
Considering Discovery was the shuttle that actually deployed Hubble, I think your information is wrong.

Really smart way of winning the public trust.
