I've never figured out why kids put airplane wings on the back of their Honda Civic either, but there's definitely a trend to 'personalize' their ride to make them stand out just like everyone else.
Are there any pic packs out yet so I can make mine unique?;)
It seems to me that this patent targets on the computer responding to what the user wishes to do without knowing explicitly what it is.
Unstructured could just mean that the user could be doodling, writing (grafitti?:) or doing something that the computer would figure out and launch an appropriate application or "fix" up the user input.
Autospell check as the user enters words? Changing hand drawing into a real line or curve? Interpreting motions to edit video in real time? Reconizing a penis doodle and bringing up pr0n? Doesn't say...
7.1 channels at 96KHz/24bits I figure 18.4Mbps (No, I'm not going to give up my DVD-A quality with speakers that will be this expensive)
8 * 96000 * 24 = 18,432,000 bits per second
Encoding this on a carrier would require at least 37 MHz of bandwidth (see nyquist et al), and then we're not accounting for error information or ways of dealing with interference (i.e. "perfect" transmission and reception)
A bit more spectrum, and my god man, the cost of this equipment will be rediculous for sending sound the 5 feet a wire could stretch!
Not to mention that wireless speakers most often use a device at the source that takes an ANALOG output and reencodes and transmits it for the speakers to receive.
This has two drawbacks: a) Loss of fidelity, which would be a step BACKWARDS in PC Audio and b) A nice big box at the back of your computer instead of a few thin wires.
And to those who would say just transmit the DD5.1 info, two more things: a) You'd need a decoder in each speaker, expensive hardware-wise and b) it is compressed and would seriously degrade "true" 192khz or 96khz/24bit sound, which I don't see how analog wireless would do a much better job either
I thought the idea was making it more simple and cluttered while improving sound, eh?
A "trimmed" version of SmartCards called SIMs are used in GSM phones. They are litterally trimmed down from a standard sized smartcard.
They are most often packaged in the original card form with cuts so you can break out the smaller form factor. Placing them back into the larger card allows them to be used with ISO compliant card readers, which software is available for to allow you to update your phone book, etc.
Java applications are the big new thing with GSM phones (more so the dedicated phones rather than the cross-platform PDA phones), so eventually this will lead to innovation for what you can do with a traditional GSM phone as the price comes down (16k and 32k SIMs are the rule with the occasional 64k in new markets because they are that much cheaper).
Brazil did this to me my last time into Sao Paulo. Through incoming passport control, they segregate US citizens into their own line to finger print thumb and index finger as well as take a few photos. Then we stand around for 15 minutes for good measure. The officer accompanying me didn't speak much English other than the word "reciprocity";)
I obtained a 1 year work visa as well, but for this to be "legalfied", I had to stop by the federal police station and get more photographs along with all ten fingerprints (8 fingerprints and 2 thumbprints?) in the stickiest goopiest tar I've ever seen. Took another 15 minutes to get that wash that shit off!
It drives the point home that they make it difficult on me because of my government's actions. The truth is since I was there on business, it didn't matter much to me, but I can see how it can annoy the tourists.
Sadly, I didn't get to stay at the beach, but spent my time inland in Brasilia and Belo Horizonte. Not much tourism, but fascinating places with very nice people.
What if you want to listen to MP3s when it's dark out?
Add headlights, of course!

A clever hack is a clever hack regardless of the canvas. I'd imagine most people that "get" 2600 would enjoy some of the same free-spirited thinking that goes on at the discussed site.
Congratulations adventurer!
Your quest is at an end for you have reached the root of NetHack.
Within, the Wizard of MS RAS has no power, the Oracle 8i speaks with utmost clarity, and the stack overflow bugs do not bite.
Further thought:
Why not keep the 802.11x coverage locallized and use a different wireless technology for the backhaul? For point-to-point you could use line-of-sight microwave, laser whatever, or use a repeating technology with more bandwidth similar to what Riccochet did before it went TU.
This would keep the 802.11 AP side "clean" for the clients and allow use of any/all channels to keep down local cross-AP interference (unlike WDS which halves your bandwidth out of the box and is fixed to one channel) and still allow a black box configuration that you could just plug and play (maybe lining up an antenna depending on the backhaul).
Then again something like this seems like a plea for regulation...
Doesn't bittorrent check each chunk against a hash from the (signed).torrent? How secure/vulnerable is this method to spoofing? Has it been done?
(I'm sure you can find some random garbage that may happen to match the hash, but making it usable in the context of the entire package and containing your malicious code would be quite a task).
I don't believe I missed anything -- a signed.torrent ensures the owner controls distribution per their copyrights. Someone posting this on another tracker would break the.torrent signature and not pass the authentication check.
I am assuming the "authentic" distributor has their own tracker(s), but this is trivial. If they no longer want it to be distributed, they take it off their tracker!
The 95% of the folks who put out torrents that aren't doing so by the will of the original distributor are the same 95% you can't trust to give you an unadulterated file;)
(Obviously this is a simplification - the information contained would be updated for signing purposes, possibly signing sections as well if the original distributor/owner/company wanted to allow anyone to share it as long as the main package is authentic)
What do you mean by the second remark? If XPSP2 is signed by Joe Blow and authenticates, that merely means that Joe Blow put something out he calls XPSP2, but I know it's not from Microsoft. In all cases, the company putting out a.torrent would be the one signing it (in which case we'd never see anything from MS as a.torrent;)
Otherwise, I see this much more useful in the manner of distributing game demos and patches, which most companies are using FilePlanet and other ilk that make me register with them separately, outside the interest of me just wanting to patch my @#$ing game, instead of clicking or FTPing the file directly like we did back in the Good Ol' Days. Instead of feeding the advertising revenue scheme of download services, they could keep a slower seed and let the users help with the bandwidth. Much lower cost than maintaining a speedy download server and friendlier to the customer than outsourcing it. After all that is a main point with the whole torrent thing and P2P in general.
P2P networks really need to figure a way for an author to cyptographically sign a file as "authentic", like you can sign email with a PGP signature. This would be another step in giving P2P nets "legitimacy".
Currently there are all sorts of miscreants out there doing unspeakable acts to poor defenseless setup.exe files which will burn the end-user and turn them off to P2P.
If there existed a secure, integrated/easy way to verify that this XPSP2 fileset came from Microsoft without tampering (publishing MD5 sums is the antithesis to easy to normal users), I would click on the.torrent or whatever without hesitation.
The authentication would rely on the Public Key Infrastructure and have chains of trust that would go back to the CA's, just like we do with SSL certs.
Does the heart-lung machine have an internet addressable IP? Could it wind up as a spam zombie?

What "security" or other risk with a turnkey standalone system? I'd rather risk the remote chance of someone breaking into my room to run CAT-5 to my vitals monitor rather than a BSOD (possible REAL death in this case) because Service Pack x broke some obscure function and failed to alarm the nurse when my heart stopped.
Do the morons at the hospitals run Windows Update on the defibrillators?
The manufacturers have tested and retested and regression tested everything that goes into those medical devices (or they say, anyway), so why deviate from a known good combination without a compelling reason?
For CDMA at least, I doubt many AP owners will want to purchase a stratum-3 clock source or better to keep the strict timing requirements, let alone tackle the technical aspects.
Most CDMA cell systems use [C]BSCs ([centralized] base site controllers) that derive timing from the MSC (mobile switching center) which in turn keep the BTSs (cell sites) in sync using timing derived from the DS1s that connect the two. The sites themselves need to know the precise GPS coordinates (a couple hundred feet off can really affect the timing in this system). The BTSs (cell sites) use a "PN offset", basically a time slot, for each sector (cell sites usually have 1-3 or 6 sides that act independantly) to keep from colliding on the same channel. RF Engineers wake up screaming in the night because a little overlap of two sectors in the system that overlap time slots will clobber usability. At 1.9GHz, weather plays a significant role (water reflects like a mirror, leaves eat up the RF which someplaces disappear in the fall), ensuring the need that the system has to be tuned constantly.
The cell phones listen to the "sync channel", then sync to and descrypt the "long code" to catch up and keep in sync with the system.
Summarizing this rather sloppy overview of CDMA, such an AP network would require 1) precise timing 2) precise coordinates (to keep BTSs/sites from colliding on same channel), 3) a strict sector/site management plan, and 4) active management of coverage. Note that this precludes anything like WDS - each point needs a backhaul or you could potentially bring the available bandwidth down by 2^(number of sectors adjacent to repeater).
Needless to say, I think the average layman is out of his league trying to link up a homebrew network in his neighborhood using CDMA.
TDMA could work with sloppy timing, but isn't that basically what 802.11b/g is now?
Theres no way that increased takings announced by the MPAA can legitmise downloading of copyrighted material, sorry but thats the way it is. The only person who can legitimise it is the MPAA or copyright holder themselves, and until that happens Im afraid you are in the cold. Unless you request a major copyright change through the government.
I sent my request in last year. I'm good to go then, right?

Not precisely true... Warez file sharing is a subset of file sharing.

Unfortunately that would demand much more processing power (big price hit!) than it does for MP3s, not to mention battery life.
We'd tell you, but that would also tip off the net terrorists.
