Comment Re:Strong enough plastics? (Score 1) 570

The problem with the current paraboloid bullets is that they are long (to accommodate more mass for a higher impulse). This causes the drag force to act behind the center of mass, and this is what tumbles the bullet eventually. When spun, the bullet stabilizes itself against drag effects to a degree, much like a thrown football.

If the aim is to shoot, we can stick to rubber bands. I think the aim here is to have a workable gun: accurate within reasonable limits (say, 75-100 meters), and lethal, or the very least, damaging. A tumbling bullet is not accurate, and likely slows down enough to be non-lethal even.

If these criteria are not met, I see absolutely no point in a printable gun. If they are, they can be a great tool for national defense militias: a network of such printers could churn out these low-grade weapons quickly and cheaply, arming militias and citizens to kill their attackers and likely take their weapon. In a sense, it could be an evolved, more usable version of the Liberator, that can potentially double as a backup weapon even after its initial use.

Agreed. If the plastic firing pin can trigger the primer, the overpressure doesn't blow the chamber and the breech apart, and the rifling doesn't transition to smoothbore after the first round, it might be worth it. But you need stronger plastics for that, and that may be past the printer's ability to liquefy and print.

To be honest, in today's society and with the current medical tech, our biological evolution has almost ground to a standstill: medicine can enable even those with the most malicious mutations to stay alive and strength and reaction speed no longer increase our chances of getting laid since they're not survival traits any more. Survival traits are now more social than physical, and as such, can be learned.

Wasn't it ruled that natural genetic sequences can't be patented, only the specific modifications biotech companies implement? And where ever did you get that stem cells are patentable, they're not even an idea to be patented. There was that case about the HeLa-line, but in that case, it was ruled that since the cells were considered medical waste, it was the hospital's responsibility to see to their disposal as they see fit, granting ownership over the cells, and their descendants (since they are identical to the mother cells).

So now it will languish because of a seriously bad rep, even before it's released, and developers will keep developing for desktop architectures (for what it'll be worth), because they expect low tablet/phone market penetration. This means they won't take the time and effort to make their apps cross-compatible (has anyone developed a cross-platform Metro app already? Is it a lot of work to make the jump between the two architectures?), there will still be few tablet-compatible apps, and the problem still won't be solved, unless Microsoft intervenes actively by developing native tablet or cross-platform apps, that are equal in capabilities between the two platforms (so no crippled tablet versions).

Trackpads usually move the mouse pointer on screen, so they can be considered mice. Unless you divide them up into active zones with no visual feedback on zone limits and functions, which means you just poke it in places, and hope you hit the button/zone you're trying to hit. All this while trying to scale and map the screen onto the touchpad: for many people, this might be a healthy mental exercise, but for those with not such a good sense of spatial reasoning, it'll be a reason to hunt down Ballmer and bludgeon him over the head with their laptops.
