How about: Study Finds Windows More Secure Than Linux (default installation, for web service, based on the threat of vulnerability and date to be patched, waited for patch issued directly from redhat instead of just recompiling the damn thing)
A quick dig txt domainname.com with a proper SPF record will yield even more useful results.
For example, I only allow relaying from our domain via our MX records (linux e-mail gateways in a DMZ).
So a simple dig of my spf record tells you this, then you can simply dig my mx records, and you've got all the info you need, including an e-mail address to contact me directly.
Thats because true spam doesn't ever check for NDR's. They just blindly fire messages off open relays. This entire concept is falwed. The only thing it will stop is messages being sent to you by valid hosts, that you could easily track and report.
The only thing this solves is admins that are too lazy/busy to investigate the spam they receive.
I was pretty amazed, knowing how secretive google is about everything. I figure I'm amongst a handful of people outside of Google or one of their vendor/partners that have actually seen a Google rack.

Once, said Hölzle, "someone disconnected an 80-machine rack from a GFS cluster, and the computation slowed down as the system began to re-replicate and we lost some bandwidth, but it continued to work. This is really important if you have 2,000 machines in a cluster." If you have 2000 machines then you can expect to see two failures a day.
Looks like my numbers were correct. 20 shelves * 4 machines per shelf = 80 machines per rack.
I was actually lucky enough to visit a datacenter in the southeast united states (which will remain nameless, but if you do a little searching, Im sure you could figure it out) where Google colocates. I want to say they had something like 18,000 square feet just for them, behind a partitioned wall. We were *not* allowed back there, despite my pleading.
Anyway, as we were walking around the 150,000+ square foot datacenter floor, when a guy came by, pushing a very odd looking rack.
It resembled a bread tray, 20 shelves if I counted correctly, with completely naked main boards sitting on them. It looked to be 4 machines per row (counting the power supplys). Each had one IDE disk sitting on a gel pad, strapped in with velcro. I personally watched them wheel 4 of these racks right by me back into the dark "Google" corner of the datacenter. Our tour guide finally gave in.

They aren't concerned with branding and marketing. They just produce units. Thats where the real money is. They need the "middle man". Let dozens of different brands market products in every country, and they'll crank them out.

Actually selecting * vs. selecting the actual rows can be much more efficient. If you have a high density table, then just pulling the entire rows and throwing them away after you're done can be a lot more efficient in terms of disk access, although you'll take a larger memory hit. But as well all know, memory is fast, disks are slow.
"Scaling to 256 Itanium 2 processors in a single node, Altix 3700 leverages the powerful SGI® NUMAflex(TM) global shared-memory architecture to derive maximum application performance from new high-density CPU bricks."
So I'm guessing its still 256 CPU's per node.
We run a 16 member citrix farm, and use domain Group Policies to apply restrictions. All requests pass through a proxy server, which is forced as the IE Proxy server, again, using a group policy.
We don't have *any* problems with spyware/adware on our citrix farm.
I'd recommend considering auditing individual user access rights, locally, on each PC. Consider implementing local group policies on each machine, and installing AppSec (check out support.microsoft.com for a free download). If the machine was properly configured, the user wouldn't have sufficient rights to install spyware/adware, barring a browser security vulnerability.
Basically, consider prevention instead of clean-up.
We're picking up 7970's for under $400, so methinks you might want to try shopping around a little more. I'm willing to bet you could save yourself quite a few bucks.
The only reason to switch to a 7970 for me was just the cool touchscreen, and being able to add a background image on the phone.
It was a government research project. You think they worked for free?

Compare the ratio's of number of crap/good open source products to the number of crap/good closed source products, and you'll be (pleasantly?) surprised that the ratio considerably favors open source software.
Quit putting "slaves" in quotes. It has a very specific definition, its not a vague term.
It means someone who is owned by another person.
Now that we're clear, is it slave labor or just incredible poor, arguably inhumane working conditions? There's a big (large, huge, MASSIVE) difference.
We just use a two port POTS voice card in all our equipment at remote sites. Gives you two lines in case of a failure of any type. One for 911 and one to try and continue some form of normal operation.

Gee...I wonder what software they run?
What software are you feeding this into? A shell script with a bunch of wget's, or a real commercial piece of software?
Seriously, I'm curious. I'd love to find some decent stress testing software for web apps.

Okay, yes this goes against normalisation, but normalisation is used to reduce redundant data, not speed up a query or reduce overhead.
The actual term is denormalization, and it can definitely produce some dramatic speed improvements.
In all seriousness, you really don't see any large porn sites being delivered dynamically. Just static pages generated on some regular interval.

Yup, right at $400 (MSRP is $395). Didn't catch it in your post, just trying to be helpful :)

I'm jon, nice to meet you. Know you know someone with one (256MB version, got it about a month ago).
I just store an encrypted KeePass database on my secure partition, so I'm not totally naked, but this still is seriously frustrating to me.
Anyone else have one? Plan on trying to get a refund?

Um, you don't HAVE to use ANY distro's package management. I run redhat and compile 99.9% of whats on my workstation, beyond the initial installation.
