And a common standard... otherwise it is VHS vs. Beta again.

The plastic bullet/cased 762 I mention in the other reply can easily kill - not out to hundreds of yards like a metal bullet in the same chambering, but plenty far out. A small rod approximately .3 inches in diameter, weighing 4 or 5 grams, with a pointed front end moving at mach 2 or so is not something I would want to have pointed at me.

German training ammo in 762x51 (aka 762 NATO aka 308 Winchester) has both plastic (mostly... the base is metal) case and bullet. A special bolt and bolt carrier was used in the G3 (HK91) to fire it as training ammo.

Interestingly enough, the Israelis produced a brass cased *wooden* bullet in the same caliber for training purposes, using war captured German Mausers.

it sounds like there's a group of people who feel threatened

You could've finished the sentence there.

Well, not just profiling. Having competent, highly trained (and properly trained) security personnel. Sure, Israel is a small country, with a fraction of the air travelers and air ports that the US has. But with the amount the US is spending on the TSA, I'm pretty sure they could do a good job funding an Israeli style system.

And on the drones, think about getting your flight instructor ticket. Our flight program here at hte community college I work for is exploring offering drone training, and I heard the other day from someone else that teh FAA is thiinking about a drone certification. If you can get in on hte early education side, you'll be set.

So.... is RedHat Linux non-Free since you can't redistribute their proprietary images/icons/wallpapers/etc ? After all, isn't CentOS the same code base, compiled the same way, with the same configurations, etc. but without RedHat's logos, etc?

Just like owning a gun is a right, but in some areas you do have to be licensed. And they are all taxes, some more heavily than others.

So... is it not possible to send/receive encrypted content when using packet radio?

Anything of any shape can generate lift in a non-vacuum, assuming it has enough velocity.

112 years enough?

Even survived 6 hours of down time...

I would imagine that you'd need some sort of specialized antenna to reach 20km, no matter what signals are being sent or what is encoded in them.

Still no mention of actual frequencies/protocols/etc

On the other hand, you could use it to nuke your own phone if the police had seized it and were using it to find evidence against you...

Depends on the school. The college I work for has been known to grant release time so instructors can create content for a new course, or overhaul an old one. Basically, instead of teaching 4 or 5 classes a term, they teach one less but receive the same pay. I think in that case, the content would be owned by the college/school.

And now that Steam is available that will keep growing. It started with 100 titles, up to 126 already.
