The Continental Army fought in uniform, under the command of officers,

Indeed, for the most part the Continental Army did. That's why I stated "particularly the militia". Many refused to wear uniforms, and not lining up in formation was considered pretty unconventional back then.

Perception may be a different animal

Which was my entire point. Can you imagine how the history books would have been written if the British won that war? I don't think it would have been very kind to the Continental army, and in particular to the militia.

terrorist scum that ignore every rule of civilized warfare.

I wonder if that's what the British thought about the guerrilla tactics of the Continental army, particularly the militia. Don't get me wrong, I'm no supporter of terrorists, but I do find it interesting how one mans valiant freedom fighter is another mans dishonorable terrorist.

Simply engineer a heat shield for the warhead that is ablative and outgasses enough to provide a protective layer around the object. The advantage of this over a mirror is that the laser's heat is carried away by the emitted gas.

For countries with MIVR'ed ICBM's, the dummy vehicles can be replaced with some sort of defensive weapon. In the case of Russia, you could have two warheads with four defensive vehicles per warhead on each ICBM, or the US could have 3 warheads with 3 defensive vehicles each per ICBM. Since they can be independently targeted, the defensive vehicles could arrive ahead of the warhead between the line of site of the laser and the trajectory of the active warhead. A nice thick cloud of opaque smoke could do the trick. And be cheaper than reflective/ablative armor.

This headline is misleading. We don't yet know what caused the crash, so it's a leap to say PTC could have prevented it.

From one of the articles I read a few days ago, it wouldn't have mattered if the system was in place and turned on. According to the article the train involved in the crash was an older one that wasn't compatible with that system. I don't know if that's true, or not, but if so, the headline is very misleading.

Cats kill at least an order of magnitude more birds than windmills do.

Yes, but the majority of those cats eat the birds. I haven't seen a windmill that can do that.

Perhaps we should start a new market by composting the bird carcasses and selling the fertilizer to farmers. I wonder if windmill ground bird compost will be acceptable for organic farms. If so, it sounds like a win-win.

What makes you think that the autonomous truck will hit the car just like a manned truck? I'd think that with the sensors on the truck tied directly into the autonomous control systems the autotruck could react thousands of times faster and more effectively than a human being truck driver.

It may be able to react much faster, but due to inertia, the stopping distance for something as heavy as a loaded truck is considerably longer than that of a car. And when a car suddenly swerves in front of the truck and immediately brakes, a slightly improved reaction time is only going to help so much. A train is an even more extreme case. Those can take miles to come to a stop do to all of the inertia.

There is no consistent approach and due to various changes, even the historical usage varies considerably

No kidding. My Corvette is usually only manned by me, and occasionally one other person. It has no armament, and scares the hell out of me when it gets off the ground, let alone leaves the atmosphere. And it might as well be parked, even at top speed, when compared to the slowest space faring vehicles.

Yeah, you best hope a stent doesn't cause a clot either, or you don't react poorly to the clot medication, or get yourself hurt while on it...

Restenosis is going to occur with any stent. The endothelial cells that keep plaque from accumulating are long gone by the time we can detect the issue. Until a vessel is 90% stenotic, it will effectively flow the same. You can postpone restenosis with drug eluting stents, which have been in use for a long time now. The elution distance is not very far, so this type of treatment does not cause systemic issues with blood not clotting like taking oral medications.

If the electronics in this stent can give flow information, then it also has the advantage of the patient not needing to go back into the Cath lab to have a catheter fished through their femoral artery to verify it. Which carries it's own set of risks. In the last few years, it has become possible to use CT to check this, but there is the radiation exposure, and a margin for error involved with that. Plus I don't know if that's become something insurance will pay for.

Considering bio-soluble stents have been around for several years, I don't think the stent structure itself is going to be a problem. The electronics, I wouldn't know. I didn't RTFA, but perhaps they remain lodged in the plaque that caused the stenosis to begin with. As far as causing another blockage, it has been well known for some time that restenosis will occur in a standard stent. Once endothelial function becomes impaired, plaque will accumulate. Drug eluting stents can postpone this, but there is no way to avoid it permanently.

Backyard Brains, a small company notable for turning cockroaches into cyborgs.

Get the cyborg cockroaches to scavenge for parts and start converting other cockroaches into cyborgs too. Once you have enough, you demand "One Billion Dollars" from the governments of the world, or risk being invaded by terminator roaches.

What could possibly go wrong?
