In my mind, the advantage to port knocking is that no data payloads are ever transfered; the authentication is done entirely via the timing of TCP control packets. This eliminates the possibility of, for example, buffer overflows in the program performing the authentication. Any vulnerability in the authpf program (or its authentication source) would potentially allow an attacker to perform arbitrary modification of the firewall rules. That would be a bad thing.
There are 16 ports being listened to, so an attacker has a 1-in-16 chance of finding the correct port. Knocking, using 16 ports and just three knocks, gives an attacker a 1-in-4096 chance of getting through. If you changed the knock pattern every minute, then I could see something like this being useful, but as presented it seems less secure.
Please define "cheap cables". Because I see lots of people who believe that the price of a cable only matters in special circumstances (in-wall installation or runs longer than 20 meters), and maybe not even then.
I've given up most TV (OK, I watch the Weather Channel), and I stopped reading Time and Newsweek twenty years ago. For a while I went with US News & World report, but lately I've been subscribed to The Economist. Not that I have must time to read the hardcopy, but as a subscriber I can read all of the articles via an RSS feed, plus they provide an audio edition that is the complete text of every issue, which I can download to my MP3 player as listen to as I commute.
The moral is, don't read/watch/listen to "mass media", instead go to what the movers and shakers consume.
It has an address book, a calendar and to-do list, a mostly-text web browser, and an IRC client. It runs on most homebrew cards; the Games-N-Music can usually be found at Walmart and Best Buy, but better ones are available online.
I promised someone a DS for Christmas, but when I went out to buy it on the preceeding Saturaday (the 22nd), every place I went was sold out (Gamestop, Toys-R-Us, Target, Walmart). I did eventually find a place that had five or six left in stock, but it took a bit of driving to get it.
I thought that this sounded familiar, so I Googled some keywords and immediately found this: http://query.nytimes.com/gst/fullpage.html?res=9406E5DF1139F931A35750C0A9669C8B63&sec=&spon=&pagewanted=all
The introduction of the cell phone into the process can change things greatly, said David Sacks, vice president for strategy at PayPal.com. He conjured a scene from the wireless future: ''Walk down the street, a few blocks away from your favorite Starbucks, pull out your Web-connected cell phone, you get a Starbucks menu, click espresso, and it's sent. And you've not only ordered it, but you've paid and you can go pick it up.''
Oh, great! I clicked on the link, and the corporate firewall blocked me, saying it was a porn site. That's just what I need, just in time for my year-end review. Thanks a lot, you insensitive clod!
And where in any X11-based window manager is there a file dialog that lets me mount remote filesystems from within it (equivalent to Windows' "Map Network Drive"). There's not. Why? Because in UNIX, network files are "special" too. So, X11 file dialogs block me from cd'ing into an automounted/network/? First time I've heard of that happening.
Or, get a backup tool that supports S3 and back everything up there. IIRC, 300GB costs $30/month for highly available, geographically dispersed, off-site storage that's potentially available from any web browser.
WTF? Your comments doesn't seem to have any relation to the topic at hand, other than containing the words, "Google" and "privacy". I don't see why your getting any moderation other than "offtopic".
This reminds me that at the time of the first atomic bomb test, there was concern that it might cause fusion of hydrogen found in atmospheric water vapor. A chain reaction of that would cause the entire Earth's atmosphere to explode, thereby destroying all life on Earth. Close, but the details were slightly different. The heat of the blast was sufficient to cause the atmosphere's nitogen to fuse. That would release more heat, which would cause more fusion. The question was, would that reaction be self-sustaining, or would it die out before it consumed all of the earth's atmosphere? We all know the answer now, but here's the official report on the likelyhood of it happening: http://www.fas.org/sgp/othergov/doe/lanl/docs1/00329010.pdf
[You] go to a bookstore and [...] pay a small fortune. [...] Or you visit piratebay and download the whole series in ebook format, then read it on your pocket reader. Cost: zero. So, your reader is free? Where can I get one?
In fact, the cost of dedicated readers is a big stubling block. And not just the initial cost, there are on-going costs as well. You need electricity to run the thing, the batteries need to be replaced from time to time, and there's a chance that you might leave the thing on a train (which instantly doubles your hardware cost).
That leaves PDAs and cellphones, which since you use them more are less likely to be left somewhere, but now you're stealing resources that could be used for email and such. And the hardware isn't really optimized for reading ebooks, so the experience isn't as non-obtrusive as a dead-tree book.
Thanks, but I'm sticking with the paperbacks for right now.
The chimp just sees a shape, it does not understand what it is and therefore can identify the position of the shapes faster and better then a human. Except, these chimps apparently do have some grasp of what the numbers mean. Go look at http://www.nature.com/news/2007/071203/full/news.2007.317.html and you'll see that "Two decades have passed since Matsuzawa's team first taught a female chimp, Ai, to recognize and order Arabic numerals. [...] Matsuzawa and Sana Inoue went on to train three pairs of mother chimps and their infants to recognize and remember numerals, as Ai had done."
Excerpt from checklist for when I get my time machine working: There was a story in Analog (back in the '80s, iirc) about an author with a time machine who went back to the late fifties and made a name writing political fiction ("Watergate") and near-term sci-fi ("Apollo 13"). There was also a book ("Rewind"? "Replay"?) in which a person writes blockbuster screenplays by stealing all of Spielberg's scripts.
Me, I'd just buy stock in select companies and invest the winnings in politicians just starting their political careers.
I'm sure a lot of UK customers are automatically pleasantly disposed towards my company when they realise I'm a bit 'local' to them, but the same thing isn't an option in the US Sure it is, the yanks just use.com.;-)
Will that someone also ignore the current robots.txt content? Because anyone using ACAP will soon migrate to a simple "Disallow: *" (in an attempt to influence your decision on whether to use the ACAP extensions), and then you'll find yourself indexing dynamically-generated, "infinite" web pages.

Perhaps synthetic photosynthesis, aka "synthephotosynthesis"?
Technically, according to Webster, The use of they, their, them, and themselves as pronouns of indefinite gender and indefinite number is well established in speech and writing, even in literary and formal contexts.
I can't call the language non-biased, but in this instance the bias does not exist in the English language itself.
That being said, the author followed well established usage.

You want to look at DSorganize, then. (http://www.dragonminded.com/?loc=ndsdev/DSOrganize)

Remake Shiny's Sacrifice for the Nintendo DS.
Until then, I'd love to see Portal: the Flash Version ported to the DS.
