Comment Re:They have that already (Score 1) 126

It's called a "train".

Nah, trains are old-school, hard-wired, and are limited to following a single track to a place miles from where you are ultimately going (unless you live/work next to a train stop).

Personally, I would prefer an IFF system.... Can I get missiles with that?

Actually, this looks like a civilian version of a system that is already in use in warships.

Missiles cost sigificantly more than cars.

Comment Re:RESONANCE FREQUENCY (Score 4, Informative) 157

I'm an Engineer, and this is the first time in my life I've heard "Resonance" and "Frequency" in that order.

I studied that stuff for a while. Had some tests on it. Read some books on it. Look into it at work.

I'm also a bit of a musician.

I'm not saying you're incorrect -- I've just never heard that phrase before.

Comment Not really the best practice (Score 5, Informative) 155

Rather than an encryption gateway, having your email client handle encryption avoids the problem of man-in-the-middle attacks between the gateway and the client.

I don't have much reason to encrypt, but Thunderbird has my certificate installed and does my digital signing. This is not unusual for a modern email client.

I'm not a drafter. I'm an electrical engineer. I can make drawings, I can follow the guidelines, but I'm not as good at drafting as our drafters are.

The drafters can understand what I'm trying to say and then make it pretty.

Let people be good at what they do and support them with staff that can hold up the spots where they don't shine quite so bright.

Comment Re:power level of a detectable signal at 1200 ly ? (Score 1) 79

It's 100 MYW:

Let's make a couple of quick assumptions:
1. Lossless, perfect vacuum.
2. Height difference = 0 and line of sight.
3. Minimum detectable = 1mW.
4. Omni-directional antenna, since they aren't aiming at us.
5. Let's also simplify by assuming there are no equipment or connector losses.
6. We'll also go with a 20MHz transmission.

P(rx) = P(tx) - L(fs)

L(fs) = 32.45 + 20 x log(20MHz ) + 20 x log (1.1 × 10^16 km)
380dB loss.

Heh, that converts to 100 x 10^30 W. It might get a little warm near the transmitter. Do we have an SI prefix for that high a number? Nope, looks like we go up to yotta at 10^24 and that's it. Unless we can use mega-yotta-watts. Sure, let's use those. 100 Mega-Yotta-Watts.

I beleive the leading guess is that the universe expands to its limit, then gravity asserts itself, causing all matter in the universe to compress into an unstable singularity.

This unstable singularity explodes.

Repeat.

Where did everything come from for the first iteration, and why is there something instead of nothing? That's what philosophers have been trying to figure out for thousands of years, why religion holds so many in its grasp, and why we've built machines to find the Higgs Boson. We simply don't know. We may never know. We'll try our best to find those answers with the tools we have.

Comment Re:Xen's biggest obstacle right now (Score 1) 62

Xen's biggest obstacle right now is KVM. I am no VM expert, but I've been impressed with how well KVM runs, supporting non-VM-aware versions of Microsoft Windows among other things. It's really fun to put that Windows screen on the face of someone's iPad and watch them freak out when they see it's not a screenshot, somehow their iPad got Windows 7 installed on it!
