Comment security through commonality (Score 1) 308

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.
then, when some marketing puke googles that : the s/n ratio blows their little analytics apart.

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

I think this is a good topic: there is alot of misconception with attempting to do this, and a huge variance in what is being attempted by all: The big takeaway: serving high-bitrate video (home movies/ blu ray) is REALLY HARD. I haven't seen a media player do this a rock solidly as a BD player / or HTPC. It would be hard to imagine a home network handling more than one high bit rate movie (40Mbps) being streamed at one time. The other big takeaway: there are tons of folks who do this who do not care at all about video quality: transcoding is a nasty way of sharing video - but then again it may suit a multi tv household. The other other big takeaway: you'll see lots of people saying that this device and that device can do 1080p. That is actually nonsensical: as any faithful handbrake user knows: its high bit-rates that bring quality: not resolution. that being said, this is a quest to balance quality and convenience - and I wish it was discussed more thoroughly than what we see right now. ie: max bitrates of media players on the market right now / suitable off the shelf HTPC's, etc.

ok, so this is unethical,
but lets look at this with more grainularity:
at what point have I reached unethical in the following situations
1. I hire a typist to type my thesis (this is before computers)
2. I hire a graphic artist to draw my figures
3. I hire a presentation firm to do my powerpoint slides (beamer for me please)
4. I 'hire' (read: give the honor of doing my research) master's students to run my experiments / write code.
5. I 'hire' (read: give the honor of doing my research) phd students to draw conclusions on those experiments

This applies to VLSI cad as well, you need wide screens and lots of resolution - of course you could get by with a 320x200 display - zooming in and out, but your productivity and quailty would suffer.
Tufte talks about this:

It is reasonable to suggest that there are other issues in presenting evidence than high resolution. Any other view would be astonishing. But the overwhelming truth is that much of the history of progress in science and in communication can be written in terms of improvements in resolution. That is the big idea here, and it should not be compromised away by shortrun situational considerations. -- Edward Tufte, July 29, 2001

The White House Listed On Real Estate Website 123

Forget visiting the White House, if you have $10 million you can own it. At least that is the price for the president's home on the real estate website Redfin. From the article: "Obviously this is an error. It looks like Redfin software pulled an example listing from the website Owners.com by mistake. That example listing was the White House. We have e-mailed Redfin for comment." I know it's historic but it still looks a bit on the high side according to the comparables in the area.

Humans can't just stare at blue sky and unmoving gauges for hours on end - we're not wired for it. Simply threatening to fire people doesn't work. You need to give their brains something to do.
