Comment last one didn't work out, either (Score 1) 197

kinda like any engineering project, I guess... pick the maximum incredible external threat, and design resistance to... uh, wait, the budget got cut HOW MUCH? OK, well, guys, let's pick the maximum credible external threat we can protect against 80% of the time for under $7 billion. make it modular so we can truck 'em in. seaming with tape is OK if we have to.

Comment the kicker is "simultaneous" operation (Score 2) 47

the conditions of test in the abstract listed were not mentioned. this is routine in cross-polarization (transmit vertical, receive horizontal) or in time-division (squintillions of telco, digital TV applications) multiplexing. but if this was going to happen on one little dinky antenna in the side of a smartphone at the same time on the same chip, the echo cancellation algorithm on chip would be the size of a SUV. and echo cancellation is sort of TDM all in itself.

I'll believe it when the flying pig hands the document off to my unicorn for translation.

Comment this whole "security" thing is bogus (Score 2) 132

there is no such thing as security any more using the common models and parameters. got to step it up, without fallback to silliness like 512 bit keys. the bigger problem is nobody has been bankrupted and sent to jail yet, so the impetus is not there to fix it as the first priority of business.

Comment printing photographically is different (Score 1) 169

the filtration banks are CMY for positive prints off positive media. for positive prints from negative media, you use RGB filter packs. for wacky shit, rules are out the window, including the "correct" chemical packs for each type of media.

I don't think you want to make 3xBW Technicolor type storage for a time capsule, you have to do everything three ways and figure out what to do with filters, sync, etc. good stable dyes on a polyester base in a low-humidity sealed container not subject to temperatures way outside shirtsleeve weather should last at least 100 years.
