Comment Local revocation? (Score 1) 39

If Apple doesn't revoke it, shouldn't it be possible to configure individual machines to revoke such certificates once they're known? Or is that secured against lest someone start putting out malware that installs local revocations of others' certificates, such as one's competitors or anti-malware developers' certificates?

Yes, but 15% of handgun shootings are lethal. Compare that to being shot with a hunting caliber rifle; that was my comparison.

That's a false comparison. Nobody carries around a hunting rifle to, in your own words, "stop a threat."

If you're claiming hand-guns are somehow a "soft" method of defending yourself, then you are sorely mistaken.

No, a handgun is not a optimal weapon for defending yourself. If someone is breaking into my house, I will grab the handgun beside my bed and go get my 12 gauge, which is optimal for my home.

Comment Re:Remember the NASA Wind Turbines? (Score 1) 178

Current blades are trucked in one piece (per blade) which is impressive to see. Three of them were parked on I-5 outside of Patterson, California a few months ago. There are a lot of net videos and photos which convey the scale.

Even at the current size they can't get through many highway interchanges and local intersections. The larger ones won't be able to ship in one piece at all.

Comment Remember the NASA Wind Turbines? (Score 4, Interesting) 178

NASA Wind Turbines approached this scale in the '80's. Unfortunately, this was a previously-unexplored area of aerodynamics for NASA, and they had mechanical stress and noise problems (including subsonics) and were all demolished. I think there was one near Vallejo, CA being taken down when I got to Pixar in '87, and one in Boone, NC, which famously rattled windows and doors.

The art has since improved. I took a ride to the top of the turbine at Grouse Mountain, that was fun! That's the only one I have heard of where you can actually get to see it from the top.

Comment Starting out with the wrong assumptions (Score 2) 165

This is starting out with the wrong assumptions.

Design a brick system that can be produced with 3-D printers, and will hold together when fabricated within the tolerances of an SLA printer. Forget FDM, it's too low precision and SLA is already achieving an equal or lower cost of manufacture compared with FDM.

LEGO is manufactured to astonishingly high precision, but I am not convinced that this is the only way to make a brick system.

Yep, been doing that for a while with GNU Radio, gr-dsd with USRP. I may get an Airspy just so I can use Unitrunker on Windows (without using the RTL dongles). Still really isn't a good digital scanning solution for SDR, although I wrote one for NBFM and AM:
