A recent Wired story about their twentieth-something server farm in Oregon
(near cheap electricity) has them at about 450K blades. Assuming a mix of old and new commodity disks averaging 200GB per blade, gives close to a 100 petabytes.
Plus MicroSoft was blathering about 800K server farms recently which hints at its estimate of a "beat-google" number might be.
The speed doubling time is still about 18 months (== 10x in five years).
Two more doublings from the 2005 or 2006 280 TFlops is around 2008-2009.
Its a version of Moore's law for supercomputing. Though processor speed hasnt been gaining as fast in recent years, improve clustering technology and software seems to be compensating.
We have the curious phenomena that the web tool becomes its own remedy.
Potential dating partners or employer and employee google each other.
The person who plagiarizes based on a google search is exposed via the professor's google search and so on.
This concept works as long as each party has equal democratic access to the same suite of web tools.
I recall reading in Scientific American a few years back that Moore's Law in appliances were going to make cheap and widespread use of cameras widely available. We are seeing that now. Can that be abused? Certainly! Governemnt police can abuse it. Busibody spies can abuse it as seen in the growing number of "candid camera" blogs.
A suggested counteraction was to reguire all video recordings madeavailable, which could be possible with the web and for commercial and government cameras. Then the public could "police the police". Already we see a little of this with GPS/Google Map/Mobile enabled blogs of all known cameras in some urban areas. Perhaps some entrapenuer will invent a little "camera detector" that will signal when a hot camera is nearby.
The "fear of God" was semi-effective in my youth (except for this activity) until I somewhat outgrew it. It still works strongly for many in the population. But they still can rationalize against it.
The definition of sociopath is someone doesnt given a "flying f**k" about what others think, whether the others are strangers or close associates. (Its kind of a circular deinition if you think about it.) Humans/primates are genetically programmed to care about what the public and relatives think about them, but a small and signification percentage (@5% I heard) evade this programming. I dont think even "TVs everywhere" will stop sociopaths either.
You want to have a profile that makes you appear fun and interesting,
yet not cross the line to appear be a total goof off or reveal too much personal detail to crooks. I believe its possible to meet both these goals, but inexperienced kids might need some coaching to find the proper boundary.
Often adults who dont understand a new technology seek to ban it outright rather than correct it. Guideline, moderation from both the public and facebook itself can go a long way to correcting a few flaws, yet preserve this new avenue of youthful communication and identity expression.
For example the Sloan telescope uses a 6 x 5 array of @4 megeapixels.
The six rows each look at different chunk of the spectrum.
There are CCD array telescopes in the works approaching a half-gigapixel.
Until the 2000s minors couldnt be primary credit account holders.
There could be a special number scheme reserved for underage credit, much like drivers licenses.
Fifty dollars a month is heaven to China's huge farm workforce where a half billion of them make about $200 a year. Until that is remedied, they'll be an unlimited supply of labor willing to work in those conditions - better than before.
I've seen a number of conflicting estimates on how much power computers and digital devices use.
One source decries widescreen TVs as the "SUV" of the 21st century . The average plasma TV consumes more power per hour than the average refrigerator, the previous household energy hog.
CMOS camera sensors are really cheap because they use coventional silicon chip manufacturing technology. They've been used in low end camera devices for years.
On average US people lie in much large housing.
They can have seperate well-equiped, media spaces.
Nearly every member of a a suburban familiy probably has their on TV, DVD player and music player, plus maybe a high-quality family one of each.
I've always wondered how American students, who cheat (copy web stuff without attribution, share test and homework) at a reported rate of 50% or so, manage to become published scholars with much lower plagiarism rates (one percent or so in various studies). This is perhaps a LITTLE less cheating than Asians, but a LOT less.
American software engineers are building companies and developing products. While international guys might be really good at small technical issues, they'll missing the big boat.
There are many MSFT papers at SIGGRAPH, the worlds leading graphics conference. Its hard to get a paper accepted there with up to an 80% rejection rate. Yet I've seen few of these results in commercial MSFT products such as DirectX, XBox, etc.
You weight a couple ounces more at the poles due to the equatorial bulge. The arctic is at sea level and little more than the antarctic whihc is at mountainous elevation.
The currently recommended shot for the first five years is up to 28 shots. Used to a quarter of that when I was a kid. No wonder some parents are overwhelmed, especially the less educated ones.
Web 2.0 == multiple cooperating web servers?

Web 2.0 Goes To Work
·
· Score: 2, Interesting
My impression of Web 2.0 is that no single web site has to engineer every one of its part, nor there must be a hardwired master-slave anymore. A travel site might get its presentation services from google-maps, its hotel list from Sabre, financial transactions from citibank, and so-on. There will be all these services sitting around- presentation, search, news, banking, streaming video, etc., etc. which can be easily glued with utilities like xml, AJAX, etc.
The Hubble will probably die by 2010 when too many gyros fail or it sinks too low in the atmosphere. There is a shuttle missile repair kit in mothballs. NASA lacks mission time to do this if it only do oneor two launches a year. Plus the Hubble orbit is too out of sync with the International Space Station to be safe. Should the shuttle get into trouble, it lacks the capacity to change between the two orbits.

At that time that SAT score was 98 percential and the admit rate was 25%. I think now the average score in in the 1500s and 12% admit rate.
If fear is a greater obstacle, than money, then you can have each eye done at separate times. That will cost more, however.

The press was showing off fake iPods last week. Similar looking case, but someone else's stolen off mp3 software.
