Suddenly, a challenger appears.
http://googleblog.blogspot.com/2009/07/introducing-google-chrome-os.html

Meh, just another linux dist.
Depends.

If they are aiming low, they will just grab a linux distribution, stick a Google logo on it, make it all friendly with big, white "ok" buttons that "just work" and that would be it.

If they are aiming high however, they are not saying it clearly, but I think that they are trying to pre-emt & command the whole cloud computing thing.

As I understand, this thing would basically be a small linux that would be just about good enough to load up their browser. And then, it is through that browser that all the rest of the goodies would be streamed from the almighty mothership Google and it's blue gene supercomputers, to your cheapo screen-terminal.

Perhaps ironic, but Google uses mostly commodity hardware. Only the powersource is custom build to provide 95%+ efficiency.

So no blue gene supercomputers, just lots and lots of cheap hardware.
And custom fitted shipping container units, with 100+ computers with walkway for maintenance.

I know that Google only uses commodity hardware. But really, right now, it's just a big database isn't it?

But the idea (in my post, not them having said anything about it), is to begin serving the ability to run programs like 3ds max or Crysis in its computers, and just stream a screen content's worth back to the terminals.

Presumably, processing power would be rationed, the same way right now everyone gets 7Gb in gmail and intelligently distributed (if someone doesn't use it, those chips allocated to someone else, until he actually does. As I am sure they secretly do with their gmail hard disk space).

Yahoo does something similar with their "unlimited mail" (of course, not quite unlimited!).
But Google also does duplicates. It's part of their structure. But, GMail database is infact derived (very similar) to Google Groups software.

This is the reason why the numbers on a google search page are only estimates. They actually fire, for each more or less independant aspect, a parallel "query", each to a different server that each has a specific task, for example, the real results, the pages at the bottom, the estimates, the suggestions, the adsense, the spelling mistake, each of them goes to a different server (of each there are lots of and in different locations). So that's the reason why, for one, it's fast, and two, the numbers can be off.

If you want to know more (no doubt you already know more), search for MapReduce and BigTables. MapReduce is how Google retrieves/computes data, BigTables is how they store it (with duplicates).

you share your birthday with at least 9 million other people in the world...
Ah, the worthy Birthday Paradox, and subsequent Birthday Attack!
As soon as you count 366 people, the probability of two people sharing a birthday is equal to 1, due to something called the "pidgeonhole principal". If you store N+M (N and M greater than 0) items in N holes, then it must be that atleast one item shares a hole with another item.

And at only a group of 23 people has the probability of two people sharing a birthday reached 50:50.

If you use the American notation for the date--that is, mm/dd/yy--then on July 8th at exactly six seconds past 4:05, the date was 04:05:06 07-08-09!

If you follow the rest of the world, then this same phenomenon will occur on August 7th.  This won't happen again until 3009 2109!  Mark your calenders!

Bah, I honestly can't stand the american date format.
Did you know the american format is really backwards? It offers no advantages.
I mean, it's not little endian nor big endian. The most stable information is not at the back or the front.


Also, two years ago, "7/7/7" people got all exciteed, you are all so 2000 years to late for that!
Same with 3 days ago. Or "pi" day.

Ok, now for some sane date formats.
The best is one found in Asia for the most part (most known in Japan): yyyy/mm/dd the best advantage is the easy sorting you can do, just alphabetical. The twentied of August in the year 2009 will always be after first of March in the year 1111.
This format is big endian, and therefore represents the most important information at the front.

Then there is the European format, of dd/mm/yyyy, which is little endian by putting the least significant information at the front.

Numbers, when written in the range 0-9, are (usually) in big endian format, meaning that part that is most important is at the front. I mean, on a scale of millions, what does a single digit mean at a million places after the decimal?


And lastly, there is the lowly and, quite frankly, IMO, useless, american date format of mm/dd/yyyy. Which is has no advantage at all, except it's more like the "verbal" counterpart, in the saying "March the eleventh". Which in it's own right is in big endian format. But why did they have to then tack on the year at the end? And even the "verbal" counterpart they used to say: "in the year of our lord, some number, on May the twenty-fifth, this and that happend".


Ok, that's enough ranting and somewhat usefull facts on dateformats and endian-ness.
Also, don't forget, the first story of Gulliver's Travels where he meets the Lilliput and Blefuscu, who are at war with each other at which side of the egg they need to break first, in other words, which endian, the Lilliput want the little endian side to break, while the Blefuscu want the big endian side to break. In fact, if I remember correctly, Swift is the originator of the word "endian" in it's modern use.

Didn't a 100,000 amp lightning struck the shuttle directly? Desipite the launch pad lightning rods?

I just heard that..... :|

EDIT: actually

STS 127 Scrub Briefing


None hit the shuttle itself... but they had to many strikes in the area.....
The shuttle did take a voltage spike though.

Not according to this:
Quote
"The launch pad gets hit all the time," said NASA spokesman Allard Beutel. "We've never had a direct hit [to the shuttle itself], though."

So who do we believe... the NASA spokesman or Mike Moses The Space Shuttle Program Integration Manager.

There was no direct hit to the shuttle but a strike was close enough to cause a spike in the shuttle systems....
That's what I got at least...

11 lightning strikes occurred within 0.3 miles of the pad

Had to because it was interesting to watch :P



Quote
Lightning strikes on Launch Pad 39A at NASA's Kennedy Space Center, Fla., are captured by an Operational Television Camera. Eleven lightning strikes occurred within 0.3 miles of the pad during a thunderstorm July 10 as space shuttle Endeavour was prepared for launch. Mission managers delayed Endeavour's planned liftoff July 11 as a precaution to allow engineers and safety personnel time to analyze data and retest systems on the orbiter and solid rockets boosters. The next launch attempt for the STS-127 mission is planned for 7:13 p.m. EDT Sunday, July 12.

This is all from NASA's Youtube account btw.
