Well, according to http://en.wikipedia.org/wiki/Statue_of_Liberty, it was not built for Egypt... The sculptor (Bartholdi) designed a similar (not not identical) statue for Egypt, but never built it.
The problem with a CD/DVD is that you can't put a usable email client on it, and it would be a pain to have a browser or im client on it.
Where would you put your downloaded emails, your bookmarks, buddies and various parameters ? A CD/DVD would be useless and would join the AOL ones in the trash can...
It's funny to see that 99.99% of/. readers complain about ads, and now everybody seem to think it's a good thing. Is it because it's a French company (or because it's Google) ?
Let's remember this is *advertisement* and that *advertisement* is BBAAAADDD. Information should be free, no strings attached.
On a side note, Vuitton & Dior belong to the same group, and Dior does not sell luggages. The example is poorly chosen. A better example could be Vuitton vs Makers of counterfeit Vuitton bags (remember all the ads for fake Rolex you receive in your mailbox).
Could be iSCSI (scsi over TCP). I dont't see any other protocol that is standard/open/... that could be used.
iSCSI works on Linux & Windows. All the traditionel NAS (Network Attached Storage) vendors use iSCSI to access block devices over the network.
The other protocols are too much OS/application dependant, and I think it would be a bad idea for a vendor to use only one of them. Using both NFS (for Linux) & CiFS (for Windows) wouldn't be cost-effective. Plus not all apps work on such protocols (especially with CiFS : ie you can't put a SQL db on a CiFS drive, but you can put an Oracle db on a NFS drive).
In some countries (like France), customers have a right to be able to make a backup of their data. Which means copy-protected disks are against the law...
They must have limited space, but apparently don't have any restriction on power.
One blade rack uses about 15kW of power (which is enough to fry a sheep...).
1/ With those blades, you'll about 7 cables (2 network (redundant) + 4 power (redundant) + 1 management processor network) for 14 blades (1/2 cable for 1 blade with total redundancy).
With your server, you'll have 2 cables, without dedundancy (and 5 cables with power/network redundancy and a management processor).
For 588 servers, you'll have 294 cables instead of 1176 (or 2940).
2/ With blades, a server is hotplug : no cables to remove/replug
(Blades are also easier to manage than standard servers)

And what's up with 4500 servers? What a nightmare! Who in their right mind would want to deploy and manage 4500 servers? If they were really serious about this, they'd upgrade to a couple dozen big-iron IBM mainframes (like one of these! [ibm.com]), where it can run hundreds of virtual Linux instances (if needed)...
Cost !
TCO : (harware/OS/maintenance contracts) costs are muuuch lower with intel boxes; Automated admin/deployment can be easy if you have the right ppl/tools.
if you have 16 coloc sites (like Yahoo!), you'd need 32 mainframes for redundancy (your IBM rep might offer you a new car)
App servers like Resin do just fine against PHP in terms of speed.
Did you compare Resin with PHP with an accelerator (PHP-Accelerator for example - http://www.phpaccelerator.co.uk) ?
PHP is FREE (so is PHP-Accelerator). Resin isn't. Many big Internet companies don't wan't to buy 100+ Resin licenses (even if it's cheap)
What I want to know is how come no PHP advocate mentions scalability? How do you pool arbitrary objects, or cache static data in PHP? How do you distribute sessions in PHP????? What happens when you want to cluster that PHP site??
Scalability is easy. You stack cheap boxes, like ppl from Yahoo! do (did you READ the Yahoo slides ?)
Caching data is easy. You've ready-to-use classes to cache output/functions/pages (jpcache, PEAR::Cache, PEAR::Cache_Lite)
Object pooling, clustering & distributed sessions are not an issue for most sites. If you need an elaborate session management, you probably won't end up using cheap boxes, OpenSource-only software,... It's the same debate than the mySQL one
No Zend Compiler (it isn't free), but they use PHP-Accelerator.
The performance hit is not so great as long as you tune your code. I've seen PHP templates evaluated in 5ms (including a mySQL query) with PHP-Accelerator.
The trouble you'll have on such sites will be more with the Apache 1 process model (1 process = 1 HTTP connection) than PHP performance.

It was built as a gift to the US afterwards.

Sure. French people can't compete with scottish people.
But the competition is biased : it's easier to get drunk with whisky than with wine...
... and type "us military victories" and the first result is titled "French Military Victories" ;-)

Here are some differences

Well... I had also many problems (mainly crashes) with Mozilla/JRE 1.3.x.
Those were Java bugs that were corrected in the v1.4.0_01 release of the Java plugin.
Have you tried upgrading your JVM ?
Or rather 3,05 (1 = 6,55957FF)...
TGV :
:
Commercial : 360kph
Record : 515kph
Maglev
Commercial : none
Record : 550kph (as stated in the article)
Well, in France most people use high speed train (TGV - 360kph, tested @ 515kph) rather than plane or conventional train...
Reasons :
For a trip from Paris to Lyon (about 450km/280 mi) :
Why take a plane ?
And those trains are quite safe : a handful of those trains derailed, but no-one was killed...
