Comment Re:I believe I speak for a dozen people when I say (Score 3, Insightful) 164

People don't understand how large and empty most of the US is.

The rest of the country languishes because everything is so far apart. Do you want to spend days on a train to get from Chicago to LA, or do you want to spend 4-5 hours on a plane? Even high speed rail can't beat a jet. In the Northeast the density of cities plus the ability to work/talk/move around on a train trumps the cost and hassle of air travel, elsewhere not so much.

"Hello air travel? It's train travel... you win."

Comment cause and effect, how does it work? (Score 2) 1105

Most Americans have a shaky understanding of cause and effect, courtesy of years of public education where feelings trump facts, opinions trump research, ineptitude trumps ability, and equal outcomes trump equal opportunity. As a result, other than saying "stop global warming", nobody really cares - they assume that "someone" will fix it, and that someone is probably "the government". You'll hear things like "global warming is bad, but I need a minivan to drive my 4 kids (which I _chose_ to have) to soccer" or "they should just tax rich people" or "blame China". Nobody wants to be the guy who actually sacrifies anything.

Are the things I care about - and I suspect most people do too, even if they don't know about it. The eed to transparently (or not!) accelerate spinning drives with SSD is a killer feature. I'm currently running a homebrew NAS on Linux and my VMWare hosts insist on doing sync mounts - effectively killing performance. By shimming some SSD in front of that, my IO latency bottleneck essentially goes away. (Lets leave ZFS out of this). "Desktop" distros will love this too - I see a simple "wizard" that asks "I see you have an SSD installed - would you like to accelerate access to your HD? Click yes and specify a maximum cache size" Presto - an instant increase in performing most tasks.

Astronauts Fix Phantom Space Station Ammonia Leak 54

astroengine writes "During an unscheduled spacewalk on the space station's exterior on Saturday morning, NASA astronauts Tom Marshburn and Chris Cassidy carried out the mother of all plumbing jobs: They detached a suspect ammonia pump, replaced it with a spare and watched for any further ammonia leakage. The emergency spacewalk was carried out in response to a troubling ammonia coolant leak that was discovered on Thursday. The coolant is used to maintain the temperature of the vast solar arrays the space station uses to generate electricity for its systems. 'It will take some diagnostics, still, over the course of the next several days by the thermal systems specialists to fully determine that we have solved the problem of the ammonia leak," said NASA commentator Rob Navias during the live NASA TV spacewalk broadcast. 'But so far, so "good."'"

You can't have regular solar panels; you need ammonia-cooled solar panels. You can't simply walk out and fix it, there's no air. You can't use a wrench, because conservation of momentum means you rotate around the bolt. And after all that and you fix it, a piece of junk from a Chinese satellite killer takes you and your new solar panel out.

This is why we're still whizzing around in LEO. Imagine doing this crap 100 million miles away when you can't "just" get more ammonia if you really needed it.
