6 TB hard disks are going to be significantly less efficient. 6TB of 64GB MicroSD cards would be 96 cards which will take up 7.92 cm^3. A 6TB hard drive is huge by comparison, close to 400 cm^3 (though the actual number varies by drive manufacturer).
OK. My curiosity got the better of me, so here it is.
First, using his number of 82.5 cubic millimeters for the volume of a Micro SD card, and Wikipedia's 1,134 cubic meters for the cargo volume of an A380 (in freight configuration), I get 13745454545 cards. Using his 20% density reduction, I'll bring that down to 10996363636. 128GB MicroSD cards exist, but they aren't mainstream yet, so let's go with 64GB. The total data capacity of the plane is therefore 610.4 EiB (exbibytes), which Wolfram Alpha helpfully says is about 0.7 times the estimated global IP data traffic per year by 2015, and around 59 times the estimated information content of all human knowledge as of mid-1999.
I looked around to see if I could find anything higher-density than MicroSD, but there isn't really anything. Full-size SD cards are readily available up to 256GB, but they are significantly more than the volume of 4 MicroSD cards. mSATA SSDs are even worse - they are available up to 1 TB, but they are way too big.
I'm sorry, but the best quote from that book is actually this one:
Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.
In my networks class, we extended the calculation to a 747 full of DVDs (the best we could do at the time). Maybe one of these days, if I have a minute, I'll go back and do an A380 full of flash drives.
In theory, Microsoft runs NTP at time.windows.com. In practice, it seems very flaky. Search for it and you'll find countless forum posts about outages.
HP (and the OP) seem to think that they have something revolutionary here.

Ever have to chase down an issue running PHP with IIS? It used to be a snap with 5. 6 made it more difficult. 7 made it impossible, if you were able to get the non-MS platform to work with it at all.
Funny you should say that. It has never been easier to get PHP running than it is on IIS 7. Two clicks in the Web Platform Installer and you have a working PHP installation. Three more clicks in IIS Manager and you have a working, and pretty well-configured, PHP installation.
Need to run two versions of PHP for different sites on the same server? Guess what? It's just a few more clicks. Enable and Disable PHP extensions? One click.
Since we updated to IIS 7.5 (Server 2008 R2) from IIS 5 (Server 2K), we have moved several sites running on old LAMP servers over to three Windows Servers and have had no trouble at all with any of the PHP installations or any of the site migrations.
It is true that it is now harder to install PHP by hand in IIS - but it makes no sense to do it that way anymore.
So basically, Asimov was right when he predicted that any interstellar travel would require death. See I, Robot chapter "Escape!" (or short story "Paradoxical Escape") http://en.wikipedia.org/wiki/Escape!
He was just wrong about whose death it would be.
Most configurations of the Toyota Sienna minivan now have the backup camera standard and the price has not increased significantly from the last model-year that offered it only as an option. This indicates that the price difference in other vehicles is much more of a "convenience charge" than the cost of the system. If it is in every vehicle, there will be no added convenience and therefore nothing to charge for.
Am I the only one who has seen drivers with a rear camera hit something or someone because they looked ONLY at the camera and not at the mirrors or out the windows. I think that when more vehicles come with a standard backup camera, there will be more such incidents, not fewer.
I measured average response time for a range of single-client single-connection to 3 clients, 10 connections each.
There were no significant changes to the setup except Apache.
Yes, I know it is entirely unscientific. No, it does not represent real-world traffic for the publicly accessible server. It's still a good indicator of improvement.
I have been running Release Candidiates of Apache 2.4 for a few months, on an underpowered and overloaded old laptop. The performance improvements over 2.2 on that same computer are really quite noticeable.
Further inspection reveals that they also wiped the router's logs. The router is supposed to leg settings changes. The last stuff it has before my first login after the password change is from July 2007, even though there used to be stuff there from last time I went in.

This. Having a separate app for editing makes sense.

The OP was asking if the NIST time servers were part of the pool.ntp.org group.
They aren't. However, NIST does have Stratum 1 Servers.
Sorry, I think Jonathan Swift got there before you... kind of.

I'm sure it's possible to make a $5000 car that meets all safety and emission requirements,...
Maybe you'd be interested in a Tata Nano.

What he wants is CRLs stored on the local machine instead of querying a web service.
The Pogo quote in your sig sums this up better than any other comment on the page.
No, the person who was home for the installation is a noob. I was upset when I came home and found out.

You can't get in to my router from outside except on Verizon's maintenance port - and I didn't know they can do password changes from there.
I can't. They set me up with coax instead of CAT-5.
Maybe they were able to change it because you were too lazy to do it in 3 years.
Not lazy. I thought other precautions would be enough.
I thought that blocking administrative access from WAN would have been enough.
