Comment It's theater... (Score 4, Insightful) 342

Not to sound like a broken record (does that phase mean anything to people or did I just show my age), but I'm not sure why this surprises anyone. It's not about security. It's about security theater. And until the TSA fundamentally changes the way they do things, it always will be.

Comment Pick a different target (Score 1) 122

There's *actual* crime happening every minute of every day online and this is the target the FCC is wasting its time and resources on?

Come on. Google effed up. They admitted they effed up. There's absolutely no evidence that Google did anything or was planning to do anything with this data and all available evidence points to a mistake rather than anything "evil". And besides, if you don't want your data sniffed, THEN ENCRYPT YOUR STUPID WI-FI CONNECTION!

Please FCC... we pay your salaries. Go after some actual fraud attempts rather than wasting your time (and my tax dollars) on this.

Comment Wait Until Dark (spoiler alert) (Score 1) 244

Many years ago, I was going to see the play "Wait Until Dark" (Marisa Tomei and Quentin Tarantino were in the play the time, neither of them very good, but that's besides the point).

I mentioned to my Mom that I was going and she said "Oh, is that the one where he uses the light in the refrigerator at the end?"

"Gee, thanks. I don't know. I've never seen it before."

I spent the play looking at that damn refrigerator waiting for the spoiler.

Anyway, someone going to see a murder mystery has no business researching it online except for maybe reading reviews of known publications if they must. If they look at the Wikipedia article or discussions of the work somewhere else, then it's their own fault for getting spoiled...

Comment Panspermia (Score 4, Interesting) 91

If it's true, it's actually not a huge deal. I could mean that life spontaneously started on both Earth and Mars (Panspermia). But it's probably more likely (Occam's razor and such) that life started on either Earth or Mars and was transported via meteor to the other planet. I would be very cool if life on Earth actually started on Mars, but it's not clear to me how we could prove which came first. -S

Comment Couldn't see that from my vantage point (Score 1) 99

I drove over to the Canaveral National Seashore for this launch. The position of the sun made it very hazy from where I was. This shot is geotagged if you're so inclined to see exactly where it was taken. I didn't see that sonic boom wave and no one I was with made any mention of it either. That's really spectacular.

FWIW, I really love this photo of the launch which was taken by a guy in the same spot where I was. It captures the Atlas V flying past the sun which I thought was perfect given the nature of this mission.

Comment Who owns the property this event is on? (Score 3, Informative) 439

IANAL, but....

In the Nevada desert? State owned property? Then I doubt they have a legal leg to stand on. However, if it's on private property, then they can probably stipulate what gets done with the photos. Stupid? Yes. Legal? Maybe.

Photographers, print this out and carry it with you at all times: http://www.krages.com/phoright.htm. It was written by lawyers who do actually know a thing or two about photography and the law.

Comment I agree. Bad math and bad physics in the article. (Score 3, Informative) 210

I was going to just mod you up, but I figured your post would soon be at 5 anyway. (if not, mod parent up!)

Yes, you're absolutely right. Lots of bad physics and a completely incorrect conclusion in that article. If there is an improvement in the thermal interface, the heatsink should get HOTTER. All of the heat goes somewhere. That's the first law of thermodynamics... conservation of energy.

You can break it down to a thermal resistance model which is functionally equivalent to an electrical resistance model. Difference in temperature is the "voltage" that drives the flow of heat (current). The heat (current) is a fixed value. The resistances are the various materials the heat has to flow through to get to the air. It can take many parallel and series paths to get out and you can build a resistance network to calculate heat flow through each "path". One way is through the IC leads, into the board, and eventually to the air... or the most direct path is through the heat spreader, through the thermal interface material, into the heatsink and eventually to the air. If the heatsink reads a lower temperature, that means less heat is flowing through the heatsink and that heat is taking a more difficult path to get out and thus the IC junction temperature is HIGHER. That's BAD.

So yes, the math doesn't add up. The thermal interface between the IC and the heatsink should be spread so thin that the thermal resistance across it is almost negligible. Thermal grease is only there generally because it's it's much higher conductivity than air and if you don't have it, all you have is air in all of the little surface imperfections of the heatsink and heat slug on the IC. Adding solid particles to the grease only serves to hold the heatsink and IC heat slug further apart, so even if it's great conductivity, it's generally the wrong thing to do.

Comment It's time for telcos to sell bits, not services (Score 5, Insightful) 204

It's time for telcos to stop being telcos and start being wireless data providers. Selling bits instead of services is fundamental to net neutrality. I know that breaks their business models, but too bad. On the iPhone, they already sell apps that use some amount of bandwidth. They shouldn't get to pick and choose the ones that affect their outdated business model. If they just sold bits and bandwidth independent of what kind of data is being carried on them, then this wouldn't be an issue and that's how it SHOULD be.

I know this isn't going to change overnight, but I fully support the FCC looking into this. It's nice to know that under the new administration they're taking a pro-consumer stance instead of pro-business stance.
