but could't such benefits also be realized by, rather than putting in a second core putting a huge cache and a few extra levels of slower but still faster than main memory cache?
i am not a CPU engineer, but how feasable would a cache/memory coprocessor be? it's sole function would be to predict what the CPU would grab next based on past actions and the execution thread entering the CPU, depending on how sure the co-processor is it moved data closer or farther from the CPU. if it screws up too many times in a row, or too great a percentage of acitons it would stop acting for a period of time so it would not interfere too much in code execution which does the opposite of what it expects.
in theory, assuming the best of the best are designing the systems and all software, software/compiler side optimizaiton for multiple cores is best, since it has a long time (relatively infinit compared to how long a CPU gets to look at the binary) however it is much easier to make sure your relatively small team of hardware engineers knows what the fuck they are doing.
moving complicated stuff from run to design time is often good. moving mentally challenging tasks from very frequent to rather infrequent is better, especially when screwing up can mean crap performance.
if you can FFWD it isn't the noskip flag that is causing the problem, just a shiatty job authoring the disc.
my Drawn Together DVDs have an annoyingly long commercial in the beginning which i thought was unskippable becuae the menu commands fail, however chapter next works just fine, but will not work on the unskippable FBI warnings.
i think each chapter has to be coded so the dvd player knows what the proper menu is from this location, if blank it does nothing.
smart sound, the rear projector TV in my house has it though it doesn't do anything now that the audio is piped from the digital cable box to the reciever
getting away with stealing $20/week? i work stocking shelves but if you get caught stealing even a buck where i work you bet your ass you are getting fired. and if i ran a business it would be the same way. i would specifically allow empoyees to bring home reasonable amounts of office supplies but theft would be dealt with swiftly and severly (automatic immediate termination, contact police and press charges) if someone is willing to steal who says they won't sell sensitive business planning knowledge to your competitor or worse, steal personal information of your customers ruining your business reputation as a safe place to buy.
i never got why it is so hard to figure out, do people honestly believe it is illegal for private citizens or organizations to cooperatew with police investigators without demanding warrants?
if a police officer uses mace on a college kid for rushing the field he/she is not a real police officer just a common pig and deserves to get shot by a bunch of gangbangers, sadly it's often the real police officers who are out investigating violent gangs and such who are the ones placed in real danger while the pigs sit around chowing on donuts and fucking with college and highschool kids for the power trip.
i think that would be even worse for the manufacturers than a generic break, and so they are likely to refuse to go along with that. if a break hits everyone they will be ok, as that is how things usually work, if a break means a possible injunction while competitors keep making and selling devices the broken company is screwed.
i hop it's SONY thant gets broken if they do use that method
situation. once you have the 40 keys you can extract the keys from as many good players as you wish, futher using those keys to extract more keys. and any 40 of the set of all extracted keys will work just fine.
i am not an electrical engineer, but this seems to be the kind of thing once broken once that could be built into a single IC or for better features loaded onto a HDMI dongle with a USB port where you can upload any Keys.txt file if they do start trying to stomp out all compromised keys.
actually it means you need one hacker and his less than civic minded buddy with a pickup truck and a crowbar to steal a shipment of HDDVD players from Joe's Electonics Shack
a virtual ring would most likely normally be used in normal speed star topology, however for cheap expansion or higher LAN speeds you could build a ring which would then, on that circuit free up the "return" path of the line to act as a second token ring moving in the opposite direction. hubs would come in three variety: static dumb hubs mad of nothing but copper and plastic would require all ports be in use to function and would be used to expand a ring (or star branch if terminated as a branch) digital hubs which could autodetect failure and electronically bypass a stalled or unused port, and switches which would actually create their own LAN and connect to an upstream ring which could fail without affecting communication on the inside ring(s)
you go ahead and get into a fight with chuck norris with just one of his legs immobilized behind his back... i'll be standing behind this wall so i don't get covered in gibs.
if token ring had evolved more it would have become physical star virtual ring, where the cable would be the send and return path for the ring to a hub with the option to, at any point link multiple machines on the same line using a simple plastic and copper connector. would actually be a versatile network topology being able to add devices without hubs just daisy chain new machines untill you have time or money to give them each their own line (a severed line would only be permenant back to a router, which would be able to auto reconnect the network around the severed branch.
it would be trivial for each distributor to implement a serial licensing system, a small CGI application which simply increments a 64 bit integer then prints the full Hex value when called.
TEMPEST gear is any variety of power meters RF recievers and anything else you can use to figure out what a chip or device is doing. most likely it would be a group of tiny coils run through a powerful DSP analyzing the electromagnetic noise coming from the TPM chip, an electronic safe cracker of sorts.
TEMPEST was the big boogieman before everyone got talking about TCPA/Palladium
it is analysis of EM radiation from electronics in order to figure out what is going on inside them, sometimes at significant range.
for example on a CRT the flicking on and off to draw black text on a light background could be detected from outside your house to reconstruct what you are looking at on your screen. some smart cards which only allow a certain number of authenication attempts can be defeated by detecting either a surge, or a particular pattern of power draw immidiately before denying an attempt, and cutting power before the failed attempt can be recorded.
such EM emissions should be useful in reading the stored secret keys within a TCPA en{dis}abled chip.
i predict it will lead to a rather lucrative black market selling the service of extracting your TPM module secret keys and using them to liberate any file you want once you get the key. since extracting the keys will require special gear but using them afterwords will not.
any device, including your computer with TPM shut off could then pretend to be your computer with TPM enabled.

suing the bar.... isn't that like challenging chuck norris to a roundhouse kick dual?
tivo sold out their customers rolling out a broadcast flag type system and only stopped because they got caught.
they can die in a fire.
terminate this idiot. i don't mean fire, i mean kill.

for me the answer is YES

implicit rights are not guaranteed by the bill of rights, explicit ones are, therefore explicit rights superceed implicit rights.
it'll be tough, SF doesn't get all that cold in the winter, though slashing animal control budgets could do the trick
rights explicitly laid down in the constitution must always supercede implicit rights, expecially implicit rights of corporations
