I took apart an older Atheros card and looked through the specs with this in mind a year or so ago. I can't remember the exact chips, but it was from the 5k series. There was a separate RF front end chip that did analog up/down conversion between the ISM bands and an intermediate frequency. The IF ran from the RF front end to a chip that contained the ADC/DAC. Unfortunately, this chip also did PHY, implemented in hardware, and I couldn't figure out a way to get access to raw samples. You can implement your own MAC in software, but you're stuck with PHY. The RF chip might be handy for other purposes, but there are plenty of other good options there.
. . . is a great book. I recently picked it up to review a few things, and I ended up reading it cover to cover. It is short, covers the essentials, and has good exercises.
The idea is to tag outgoing messages in such a way that legitimate DSNs are distinguishable from illegitimate backscatter (which can then be discarded).
Many people have pointed out reasons why this kind of thing is probably a bad idea, but if you still want to do it, ImageStream sells hardware platforms that can include several multi-port ethernet boards. There are reasons why they are marketed as routers and not switches, but they might be useful as switches for some unusual purpose.
Points are awarded for getting legislation passed with no regard whatsoever for the quality of the legislation. No points are awarded for voting against bad legislation. No points are awarded for repealing bad legislation.
The only reason angles are easier to measure is that we have lots of angle measurement tools. All we have to do is build spread measurement tools to make spread just as easy. From playing with the protractors, it seems to me that it would be just as easy to learn to eyeball spread as angle, with the possible exception of lines that are very close to parallel or perpendicular.
I recently tested appliances from CipherTrust and IronPort that use TrustedSource and SenderBase respectively. The CipherTrust unit yielded an unacceptably high number of false positives (0.8%), partially due to bad data from TrustedSource. The IronPort unit performed much better, but I have concerns about the Bonded Sender program (and if you are using SenderBase, it seems that you have no choice but to honor Bonded Senders). Since implementing Exim/SpamAssassin/ClamAV, I've noticed that 10-20% of our incoming email coming from Bonded Senders is identified as spam, and nobody is complaining about false positives. YMMV.
According to the occupational therapist who helped me recover from a repetitive stress injury, repeatedly bending extending your thumbs down from your keyboard onto such a device is one of the worst things you can do.
Yes, the Make presentation is very well done. I just got a box from O'Reilly that was supposed to contain my 5-in-1 cable parts, but it turned out to be full of Billy Hoffman's card reader parts. So I get to try it out tonight before boxing it back up again. Woohoo! (If you're reading, Billy, I hope you don't mind.)
You mentioned that he likes music. Has he ever tried singing or playing an instrument? Learning to play music is not only fun and personally satisfying, but it promotes motor skills (with instruments), pattern recognition, arithmetic, cooperation (in ensembles), and much more. I'm pretty sure I learned to read English before I learned to read music as a child, but I think it might have been easier the other way around. Don't feel like reading music is a necessity, though; many outstanding musicians never learned to read, and that's just fine in some circles.
By using reinjection techniques such as aireplay (part of the aircrack distribution), the time to collect a quarter of a million packets can be as little as a few minutes. I'll be discussing this in part two of the article.

Putting Google to the Test
·
· Score: 2, Insightful
Even better: all-party "back care"
Feel lucky and you can't miss it. The problem was that the tester didn't use google at all for this one. He thought the parliament web site's built-in search would be better. They say they're testing google, but they're really just testing the surfing habits of one guy (who uses google when he feels like it).
It would be interesting to see a more scientific study along these lines: more information targets, more users, and some kind of standardized way to measure time (including travel time, etc). Except we all know how it would turn out. . .
This sounds like the method I saw demonstrated at Rubi-Con 2002. This demonstration by Jon Erickson was very impressive and attacked traditional crypt(3) Unix password hashes. Use MD5 passwords!

TFA doesn't claim a method for detecting eavesdropping. Bad summary.

I've taken a first pass at designing protractors to measure spread:

I'm a wardriver and I use 802.11a. About 2% of the networks I find are 802.11a as opposed to b/g.
For Linux support, take a look at madwifi. I use it with kismet all the time.

That kind of thing is potentially possible with AirJack.
1000 Hz is actually about two octaves above middle C, not one as the article states.

It has definitely become a generic term. I'd like to see the courts support Apple so that we can all use "Unix" without fear.
