QoS settings on your local router only affect upstream (from your home to the ISP) packet ordering. Anything you do there will have no impact on packet queuing/ordering downstream (from the ISP to you) - this is being performed by your ISPs gear. Downstream bandwidth is commonly larger than upstream bandwidth, so this problem is frequently hidden - but if you have lots of data coming down, no QoS settings on your local gear will in any way impact the priority for packets coming from your ISP to you.
The SuperTalent Pico drives (in particular the C) are smaller. I recently purchased a 4gb model for half the price of these. You can also get the Pico with 8gb. I am not impressed with what Corsair is offering.
With a name like Joomla I assumed it was written in Java (Java Object Oriented blah blah....) and almost stopped digging any further. Is it bad that I automatically assume that any technology whose name begins with J is written in Java?
If you are interested in having high quality time in your datacenter, you will look at having a non-portable GPS unit. At a previous jobs, we had a 1u rack mount time server that synchronized itself via GPS through an antenna on the roof. Similar to these. Of course, at a certain scale everything is portable.
I've never understood why there wasn't a big pile of "spam filtering" add-ons for Thunderbird. The Mozilla add-on architecture seems like it should make it a breeze to build them, but I have never found any that do anything beyond DNS type checks.
Something you might want to experiment with is Quantian. It is a bootable linux distro (knoppix descendant) with clustering (openmosix) and a huge variety cluster capable scientific & financial open source tools built in. It is a very quick & easy way to set up a cluster to experiment and see how you application could be altered to work well in a massively parallel environment. I've never seen a quicker or easier way of building a cluster. With Quantian and a pile of networked PCs, you can literally have a openmosix cluster in minutes.
I work for a large bank, doing very much what you describe.
Our processes tend to be more computation (than data) heavy compared to what you describe, but we are using lots of clustered computers. Take your 10,000 trades and split them into chunks of 100 trades and have separate machines value each chunk and reassemble the results. Depending on the nature of what your software does this may or may not make sense. If you can split your workload into small chunks that can be analyzed independently you can achieve much better throughput.
The newer cluster/grid software can be really shiny, but you don't always need it. Plain old PVM can still work wonders. Also, a lot of the commercial cluster software out there isn't well suited to this kind of high performance computation clustering.
I co-host the Firefly/Serenity podcast The Signal. We have already interviewed Adam Baldwin (Jayne), Gina Torres (Zoe) and Ron Glass (Book) and they are all really behind the movie & the Firefly franchise. To quote Adam "Joss called me up the other day and said 'you should see the movie now (with all the effects & final music in place), it is so cherry!'". They really show an enthusiasm & devotion beyond what one would expect if it were just another acting job to them. There are a lot others grass roots efforts like ours out there promoting Serenity from the bottom up. Its very exciting to see the groundswell of anticipation build with with the advance screenings & now other new clever marketing tools that Universal is using.
I'm part of the team that produces The Signal, the only podcast in the 'verse totally dedicated to Firefly. http://www.serenityfirefly.com. The response from listners has just been amazing. We had to switch providers 12 hours after launch because of bandwidth problems. I'm sure the international trailer is about to have the same problems. Serenity is definitely one to keep your eyes out for even if you never saw the TV show.
IMHO this is how it should happen. Standards should be set high to give the browser makers something to aim for.
Back in the early days of anti-virus software the ICSA labs (I think it was the NCSA labs at that point) started certifying AV products. Their test was pretty simple, it required identification of %100 of the common viruses in the wild that they threw at it. No AV product passed it when the test first came out. By setting the bar high it drove competation in the marketplace and spurred on all the AV vendors to improve their products.
Not only easier, but also more secure. A common username and password is only 1-factor authentication (they're both something you can know). Using a username and biometric is 2-factor authentication (in this case, someting you are and something you know). For 3 factor authentication you need to cover: something you know, something you have, and something you are.
Biometrics stored for authentication are stored in a reduced, non-reversable format. Its designed to be searched and matched, but not extracted.
Middle Atlantic Products makes some nice, inexpensive rack hardware in their musician's section that's suitable for a home rack. I have one of their 36" racks and its served me well. In it I have racked a few homebrew PC's, mostly with rack-mount cases purchased from NewEgg. Decent rack-mount cases, not overly priced, and many will take standard sized motherboards and power supplies.
There are other harmful things that data can wind up doing that Perl can't check for.
This isn't just a Perl problem, its a problem with any language.
Things like being used as SQL queries
I don't see why people get so bunged up about SQL injection attacts. The main reason they're effective is because so few developers know the right way to move data between their programs and sql queries. There's a very simple solution to this problem that can be used in Perl and just about every language I've ever seen: don't pass strings straight into your database queries, use varbinds. Not only does this technique prevent security problems, but it can lead to significant increases in database performance.
In addition to selling complete racks and cabinets, Middle Atlantic Products has parts you can use to make your own. They have some pretty details dimentional drawings of the cabinets they sell which should be good enough to base your own plans on.

The community of crackers that commits website defacements considers it "uncool" to deface windows servers (because its "too easy"). Their targets aren't chosen at random, from all the webservers out there, but with a delibrate intent to prefer Linux targets to Windows targets.

This kind of attack hardly an invention of the movies. The salami attack has been around for a long time.

in The Patriot he was Capt. Wilkins a loyalist (not a major part, but a major movie)
In the last 2 seasons of the X-Files he was the super soldier. I think he was in around 20 episodes.
Check the earlier IMDB link for a full list of everything he has done.
Yeah, Adam hasn't really done much between My Bodyguard and Firefly..... only Full Metal Jacket, ID4, The Patriot, X-Files for 2 seasons, etc...

Why not get a regular server and a solid state disk? Check out the Solid State Disk Buyers Guide

The Internet Archive (archive.org) has large collections of video, audio, and text. I've always wondered why they do not have an image archive.
WIthout arguing the stupidity of the idea....
Why GPS. That's seems overkill. Why not just allow the pump to read the odometer?
