If there is any overhead in parallelizing stuff, the overhead will quickly add up. All your queries will end-up being slower, not because they don't use all available cores, but because they will have to wait to start because of lack of free cores.
IBM had hard disks in their mainframe computers that had more than one head assembly. I am not sure if they could read or write to the same surfaces or were just assembled in a way one head acted on one surface only but it is easy to imagine a high-performance drive with more than one set of heads that can travel independently.
And if your database server has only one drive one one controller, you are not really serious about it.
"but most nuclear thermal engines have a poor thrust to weight ratio for launching from the surface"
The Soviet RD-0410 seemed promising. STNP and Dumbo too. It's not perfect, but if you couple it with a cheap enough propellant (the 0410 used LH2, which is not cheap), you may have something as a result.
Wonder what could be done if we could use water as a propellant on a nuclear lightbulb design.
Riding a chemical rocket to space has never been safe. And, given the energies, tolerances and limitations, won't be for the foreseeable future.
I am a strong supporter of nuclear-thermal mostly because by packing more energy, you can build more robust spacecraft. Cost increases exponentially the more sophisticated manufacturing you require to make your spacecraft rugged and light. If we could build spacecraft to aircraft or lower specs, cost would decrease impressively.
A solid-core lift-off stage couple with a liquid or gas core for space operations would open up a lot of interesting possibilities.
The problem with this is the confusion between expression and facts. Wikipedia should restrict itself to information that can be verified as true. Freedom of expression does not apply there - it's an encyclopedia, not a message board.
It wouldn't do away the Flash-infested web in a day, but a 95% desktop coverage of Silverlight would do a lot to erode the Flash advantage, specially in the RIA arena.
And I am quite sure Windows still comes with an old version of Flash. XP did. It's been a while since I last installed a Windows desktop
I take the challenge under the condition we measure time from start of implementation (disclosure of the problem set) until, say, a couple million pages are served from the test equipment.
Given a sufficiently complicated set of functions, it's safe to assume that by the time the C code is running correctly, the HLL implementation will be days ahead.
Circa 1987, I remember grades in numeric calculus clustered around two values, a higher one for the students who used BASIC-programmed CASIO calculators and a lower one, for students who used HP RPN-style programmable calculators. A higher level language is not an advantage I would give up lightly - the BASIC users were able to finish the tests with perfect grades in a third of the time their RPN counterparts. This motivated a rule change forbidding the use of programmable calculators in the following years in these tests.
It's surprising because there was a Unix/X version and Photoshop is known to have a portable core with platform-specific front ends for Mac and Windows. All they would need would be to dust off their X front-end and patch it up to match the other platforms.
Unfortunately, that wouldn't help Flash support in future versions of Windows.
About the fungus, you could depressurize the habitable modules while in "storage". That probably wouldn't kill the fungus, but, at least, would halt its development during the time they are not used.
"If people think that a crappy browser being too is too integrated into a mediocre OS is unfair, then WRITE AN OS THAT PEOPLE WANT"
When you reduce that "PEOPLE" to all people who matter (namely, the folks at Dell, HP, Acer, Lenovo and Toshiba that more or less decide for the whole market) you will realize that an OS that doesn't suck isn't high in the priorities list.
It's like Project Mojave: it was not designed to make end-users reconsider Vista and it didn't even care if that would irk end-users - it was designed to reassure OEMs that computers built to Vista's specs would provoke a favorable response in end users.

It's a balancing issue.

"it wouldn't even lift its own weight."
Sorry. My math was off by an order of magnitude. It looks now it's 10% as promising as I thought it was ;-)
And I am not sure I would like to be anywhere close to a hot exhaust of Lithium vapor.

Not at all. Orion is only to be used if we need to evacuate the planet as nobody sane will want to stay behind when all spaceships have departed.

It was OS7, IIRC, not OS9 ;-)
I run HP-UX, you insensitive clod!
And, IIRC, Solaris zones allow you to run multiple, different Solaris versions.
"round them all up to labour camps that have a Work is Freedom banner at the front gate?"
Actually, they would be flown in space DC-9's and placed around volcanoes...
Can any religious person be considered really sane?

"still not clear on why Intel would cannibalize Itanium sales (new release delayed again)"
Maybe because the next Itanium can also possibly be the last?
Sorry. It doesn't work with my OS of choice and that's pretty much a deal-breaker.
There is an add-on for those who can't get rid of their vi habits
Sure... Remember Microsoft against IBM (Goliath ended up with the sligshot soved up its ass twice), Google against Digital...
Just to name a few...
They were using mostly 41s at the time I took that course, so, I guess it happened before the 28.
I think RPL appeared after the 41s. By the time the 48s started showing up, I was graduating.

"it's surprising that apps like for instance Photoshop aren't available for Linux already"
That would be the surest way to make Microsoft push Silverlight as a critical update and eliminate Flash from any future Windows versions.
Adobe is more or less a hostage here.
