Of course there are other factors. But regulation of gun ownership is one of them, and regulation of gun types allowed for private use is another.

Most countries with high gun ownership rates and low murder rates tend to have hunting rifles, not assault weapons. They also have extensive systems that work to prevent guns from coming into the wrong hands.

This whole clichéd genre of "X is also potentially deadly, too, therefore weapons are unfairly singled out!" is absolutely free of any rationality. Guns make murder happen faster than other potentially deadly things. That's why people who want to be able to kill buy guns rather than propane tanks, as any cursory look at standard military equipment would indicate.

It's a matter of efficiency and scale. A spree shooter gets a lot more people before the police can disable him if he uses a gun. As it were: Duh.

The problem with your analogy is that lugging a propane tank into a classroom is probably going to get you some questions people would insist you answered. And you'd be hard pressed to stop them because you're busy lugging a propane tank.

My first thought is: Good luck syncing audio to that!

Second: Good luck doing meaningful digital compression!

In professional broadcasting - _unlike_ the camcorder a mortal can afford - rolling-shutter is under control, as is a lot of other Bad and Wrong stuff that consumer cameras do. (Here's one you can easily check at home: Point a TV remote at it, and press buttons. Do you see the remote LED lighting up? That means it doesn't filter IR, and that wreaks havoc on colour fidelity!)

In Norway, the public broadcaster broadcasts 720p50 simply because people watch TV on flat panels, which means that if we sent 1080i50 the TV would deinterlace internally - and deinterlacing is nearly impossible to get right. 720p50 from a hefty box full of ASICs gives much, much higher effective quality than a home user would get from 1080i50, which is the normal HD format until 1080p50 infrastructure becomes adequate.

1080p25 is not something you want. It's really only useful for film material shot at 25fps (as most made-for-TV film stuff is). Frame rates that low incur several restrictions that you cannot process your way out of, like the "safe panning speed".

Some errata:

In cinema, exposure time is a function of frame rate and "shutter angle". The shutter rotates over the film, and by varying the angle you can get higher shutter speeds. IIRC, my Arriflex (made for TV, thus geared for 25fps) maxes out at 180 degrees, meaning 1/52s.

Digital cinema cameras do not have high-speed shutters (unless you set them that way, just like with film). Indeed, since there is no mechanical requirement to blank away the film while the claw advances, you can actually have smaller shutter angles/greater speed.

Yeah, as long as you can sit directly in front, they do work pretty great. Had one for years. Too big to haul away, so I sold it with the house when I moved.

But its nice to actually be able to see what you are eating and drinking in a Sports Pub these days without them having to dim the lights just so that people can see the rear projections screens mounted like a sword of Damocles over the bar. The modern bright LED screens do so much better in such places.

You're likely comparing these to CRT rear-projection TVs, which were indeed dark - but that's apples and oranges. A DLP rear-projection TV is very bright even in normal lighting. It's essentially a high-quality DLP video projector with a built-in reflector and projection target.

In fact, the greatest damage moderates and left-wing could do to the right wing extremists is to invite them to freely speak their minds. The resulting spew of homophobic, sexist, and racist non-sequiturs would likely shift most people just a bit to the left.

In my experience that's a fallacy. If you say that spewing hate-filled bullshit is "okay" and "harmless", it will catch on.

Dismissing dangerous political ideas as somehow "inherently self-destructing" flies in the face of all experience with human history, which includes a lot of dangerous political ideologies - like Communism and Nazism.

The reason preposterous or dangerous ideologies tend not to catch on in developed societies is because people react to them. If people stop reacting to them, they catch on.

Another approach would be to add an abstraction layer between the hardware and software very much like what is done with virtualization, Java, ZFS, LVM, DirectX, Crossbow et al. That would make the software more independent of the underlying hardware...

Isn't that basically how CISC works nowadays?
