Google, mainly because they are cheap, have custom designed the lowest power per petabyte and petaop than any other server farm in the world (something like 3 million nodes in 60 data centers). The bad news is they have the most petas in the world, so their total carbon footprint is high.
On the other hand, as the most on-screen net application, someone calculated they could save a lot iof carbon just from change white background to black!
I've read, probably in Technology Review, of people making this for 3rd world countries where bad drinking water is rampant. I think they've gotton costs minimal (@$15) and reliability high.

Hubble is an extreme case. Its lifetime cost is approaching $5 billion, but is arguably the most productive astronomical device ever. Its initial capital cost was $750 million, doubled by the first shuttle accident delays. Add 3 or 4 half billion dollar service missions and operating costs over $200 million a year.
These names are from Captain Cook's south sea expeditions.
Once they get a theme for a region, they continue.
Otherwise its girlfriends, kids, goofy shapes, etc.
Earth cant send probes to Mars each 26 months when the energy requirements are minimal.
the last cycle they just sent two orbiters (getting interesting results). But next year they'll land near the polar and dig for water ice. The 2008 laneder has no wheels, but the next one in 2009 is the largest yet. Its the size of minivan and will use retro-rocket landers instead of air-bags, and will be mostly nuclear powered instead of solar.
I presume they'll keep a low-key program with current Rovers after May. Unexpected longevity complicates NASAs budget. Sometimes they turn them off before they are completely dead like Magellan and Galileo. (Actually they crashed them into Venus and Jupiter for terminal science experiment and to prevent contamination of Europa.)
Opportunity got lucky and landed in an area with clear evidence of water sedimentation- hematite percipitation nodules and layered rock. Otherwise I expect Victoria to be all not that different from Endurance crater in 2003.
On the other Spirit took a couple of years to find evidence of water. The first couple years it crossed a volcanic basalt landscape, may with slight evidence of water healing in rock cracks. In its current area it has crossed bright sulfer salt soils - a clear sign of water. Spirit is very gimpy now. A couple meters a week is good progress.
A lot of the terrorist cells in European countries were recent immigrants from the mid-eas t or children of such. The latest German arrests were bland-hair-blue-eyes that could have come a Hitler youth camp. Theres always been a strong anti-establishment youth culture in Deutchland, now expressing itself through the Al-Caida brand.
A few years back, some European countires became infatuated with merits of palm oil- then thought to be the most efficient biodiesel feedstock. So farmers basically tore up thousands of square miles of jungle in Indonesia to meet demand. Then someone calculated the lost forest would take centuries to replace the carbon-recycling of existing vegetation with biodeisel.
Farmers are smart. They recognize short terms profits as well as any other entrepeneur.
Ideally you'd like to palnt these crops in carbon-poor areas like rangeland and desert. But farmers will convert rich croplands and forest for even more production.
Words kind of look like cars in a train. Some are longer and shorter than others. Some have big "wheels" (descenders) or thingees sticking up. I have word shapes memorized for standard modern fonts, but if see a strange font or handwrighting, then I go back to letter mode. I thing the "shape" mechanism is why the scrambling the letters inside a word, but not the first and last character, is generally readable.
You have to crosscorrelate two sources to created an effective larger aperture.
(From recently deceased Stanford Professor Ronald Bracewell's textbooks.)
Radiowaves vibrate between kiloHertz to gigaHertz. Current electronics is fast enough to capture, transmit, and record both amplitude and phase of radio signals. Its not fast enough for optical teraHertz yet.
Before signal processing was fast enough they cross-correlated the analog radio signals. This is how VBLI astronomy works.
The do this with optical signals from fairly close telescopes (hundreds of meters) using special optical pipes. They can simulate a couple hundred meter telescope this way. One of the telescope clusters in Chile has this ability.
Something like three percent of the US population produces and processes enough food fo r the entire US population, when it took 70% when the country was founded. Thanks to technology, non-renewable energy, and better business organization. Farmers use GPS, Google Maps, wireless, spreadsheets, etc. to manage their operations now.
I was starry junior high school nerd in 1968 when the movie "2001: A Space Odyssey" came out. It seemed like most of those inventions would be likely 33 years from then- a computer as smart as humans, computer graphics, routine orbital and lunar travel etc. Especially when the moon land landing was just around the corner. Only computer graphics exceeded anyones expectations in those 33 years. (Yes all the computer in 2001 were hand-drawn animation cels, because computer graphics was just some white lines on an oscilliscope then.) The energy crisis, the cold war, disappointment with big government programs all intervened to slow down space exploration. I rememebr crying seeing "2001" in 2001 because all those dreams were crushed.
I not longer affliated with a university. But it wasnt too much of a problem to visit a library and read journals on the shelves. But now about 1/3rd of journals are electronic only and universities arent as generous with their library computer accounts. It may be worht suscribing for a few work-related professional societies, but the dozens I'd read previously. Kind of like a return to the dark ages. Science progresses by open dissemination of results, but it seems to becoming more clannish.
Its a lot like our company could offer its software on 20-30 platforms (different CPUs, OS's and releases) at a time, but generally only the three most profitable. Recompilation to a new platform usually just takes hours at most, but we do exhaustive testing, spend months going through FTC export compliance, etc.
I beleive auto companies have to do the same with each new model- pollution controls, mileage claims, safety, etc. Honda Fits and Smart cars were delayed at least a year because of these certifications.
When you raise children, care for the sick and infirm you gain a broader perscpetive of life. Nerds are mostly young and health and sheltered from the worst life can offer.
I saw a a piece of experimental theater at Boulder Colorado last week called "Calculus, the musical". It has about a dozen songs and music videos sung by a man and women and progress through the chapters of a first Calc course. They play various characters such as Newton, Liebnitz and Hooke. It was amusing and good. They are doing cities too.

And those people have everything from toy telescopes to the "SUVs" of scopes driven by supercomputers.

The more powerful vampires are able to follow the night and and be awake for the perpetual night.

Just another incident in the latest iPhone crapola. No wonder Steve has to drastically cut their price to get them out the door.

Is US spammers?
Soviet-area spammers?
People who bought early iPhones probably impressed dates with their wealth and coolness. That was worth the $200 difference.

All three of these were authored in the UK. Is this a continuing pattern?
Nothing realy technical or for nerds.
