Comment Re:WebOS - Try Samsung (Score 1) 394

well, if google goes vertical in the tablet market (I think they will -> there is no other way), samsung will be left out in the cold (I also believe microsoft will go vertical in the tablet space as well). There is really no way to make money in tablets without having an appstore, and media to make addl money off of. We already see that amazon is going in this direction.

yea, I am in this area, I'll see if I can a look at the manuscript, thanks! I am looking to make constructs on FPGA's that the EDA crapware won't allow, at least with some elegance / automation. Ive been forced to make my undergrad student use xilinx's "fpga editor" - although it works for what we are doing, it is tedious and not very repeatable or scriptable. why are these companies so fearful to release the specs on the bitstream / architecture?

trying to find morality in war is quite futile: so to say that dropping bombs on "innocents" is bad, sorta seems like saying dropping bombs on non-"innocents" is ok. none of it is good. but that is why we call it war and avoid it at all costs (if we can). unfortunately, _some_ people won't listen, and they need the motivation of bombs to get them to the negotiating table.

you could also modify the bitstream and release malicious code into a STB. another thing: sometimes these STB's are more 'trusted' because the engrs assume that the bitstream/designs in the FPGA are secure. Its a great place to put a trojan, monitor packets, etc. this is not a good thing. It will mean more expensive hardware in the future.

ok, so obscurity isn't working... time for something different.
Use a username that is a slight modification of a VERY common person. bradpitt, obama, billgates, sjobs, stevejobs, ibm, microsoft, etc etc.

Comment Re:For the airplane geeks... (Score 1) 317

the last time my gps didn't work was in the middle east - it is by far not reliable enough to be used without an INS. And is suscetiple to 'interference' from many sources.

Instrument flying is based on rules determined by blood: almost every rule is because someone bit the big one for relying on something they should not have.

Basics of flight: pitch/roll heading/altitude, everything else (except the landing) is gravy
Back on topic: True headings ARE used, I believe above the artic circle - as mag gets confused up close to the poles.

don't worry about secure erasing a flash drive - it can't be done. why? - many reasons, but the chief one is the wear limiting circuitry that swaps out huge sections of the memory, and the fact that the reported memory of an ssd is much smaller than the actual memory. - thus: you don't have access to all of the memory cells so that you can erase them. some researcher somewhere was able to pull "erased" data off of an SSD, by removing the chips and checking them with a logic analyzer / test bench - an actually easy thing to do (easier than platter manipulation i bet) j

yea, well - sort of: these advanced approach ( & autoland) systems are really complex: some planes have 2 or even 3 autopilot systems - they check with each other for agreement, etc. the air data sensors and all kinds of other systems must agree - anyway: I say all that to say that we must fly the approaches - it can be done in the cockpit or the sim, if there are faults - you report them (radar altimeters disagree etc) and the system is checked.
a little history: Aviation had been thoroughly plagued by equipment failure in the past - many more pilots died due to bad design, manufacture, or assembly than to human error (or even combat).
so inherently, we don't trust computers, engines, fuel ourselves, or controllers. That is why we have 2 computers, 2-4 engines, many fuel bladders, co-pilots, and radar.
anywho - this issue of co-pilots goes deep into human factors: a wide and vast field - some folks who are into HCI may have studied some parts of this - and from this we have learned that having at least two in the cockpit is way better than one (three is even better). Just please understand that a co-pilot is NOT a backup pilot in case the pilot has heart failure. he/she is an integral part of a team that keeps the plane going where its intended to be.

Commercial airlines are already required by law to do a certain percentage of their landings automatically. They just don't tell you...

what you mean is that pilots must remain proficient in Cat 3 and 3a approaches - so they must maintain currency with those procedures by performing one every once in a while. This currency can also be accomplished in a simulator.

Cat 3 and 3a autoland has been around for a long time. (1965)
http://en.wikipedia.org/wiki/Autoland

Trying to do one of these without a co-pilot is ill-advised (1 set eyes on instruments another looking out for the runway environment) - don't forget about radio calls, communication with home base / fuel management / emergencies / etc. I flew very complex, very large planes - and I can tell you that there is a real good reason for at least two in the cockpit. j
