... negotiated a bunch of privileges for them as well; fishing rights are still being negotiated, because dams are both water resources and encroachments on obligatory rights-to-fish

not without provocation

no, rather joining them when the Atlantic became a battlefield (according to some hisorians)

Poisoning our own soldiers with a pesticide? Relevance?

Antitank weaponry used appropriately... no issue there, just minor waste cleanup

No, selectivity rather than area weaponry.

Huh? Iran first looted our embasssy, kept our diplomats as hostages, a clear act of war.

Nothing in such a list really compares with, for a modern example, the ongoing invasion in Ukraine. Mostly, it was when we were all infants. Biggest regime change during that period, was Mao in China; no US involvement to speak of.

Natives are welcome to return to being hunter-gatherers living in tents with no electricity, no jeeps, no horses, no guns, no medicine, no written language, and no internet. Then they could possibly find someone from another tribe to torture, in the traditional manner.

Few seem to make that choice.

Saved a million lives probably.

Europe has been at peace, Pax Americana, for 75 years now. I think that's a 2000-year record.

Well, it was until Russia started this war. Patton wanted to keep charging east into Russia.

Take a look at this picture, John. It illustrates how Warren Buffett's greed takes precedence over the Fort Laramie Treaty.

The civilians are indigenous people at Standing Rock Indian Reservation. Warren Buffett sent in outsiders, the uniformed quasi-military force, to protect his financial interests.

Danke,

More retarded foreigner spouting his retarded disrespect, trying to get a rise out of folks in this group. You went from someone with a little intelligence to a complete buffoon nearly everyone in the group has blocked.

You are a goddamned utter idiot.

If I were rich, I would go around the globe erasing absolute dumbfucks like you.

I suppose the CIA sponsored overthrow of a democratically elected government in 1953 on behalf of the Anglo-Iranian Oil Company was fine?

Water spray is rarely lethal.

Are those Indigenous Peoples being hosed down? Dressed in jeans and tee shirts and running shoes and baseball caps?

Interesting Native American name, Dave Archambault.

Two wrongs don't make a right. You need to offer me something more than non sequitors if you want to convince me to change my mind about how the Fort Laramie Treaty was trumped by Warren Buffett's greed.

Danke,

So the doctor could not help after all.

That fails any kind of reality check.

... which also fails a number of reality checks. Dr. Fauci, for instance, was clearly at work on the wrong continent to connect with the outbreak. A hundred more conspiracy rumors can be found, or created, but ought not command our respect either.

RationalWiki calls this sort of thing a Gish Gallop.

The laser emission angle is 29 degrees, no worst than an LED. If it's pulsed, I'd expect the average optical power to be microwatts.

Except that this is hardly a beam; it's a wide fan. Just because it's a laser doesn't make it dangerous. Power density makes light dangerous.

I don't think ST would sell it if it's dangerous.

Around here, we have swarms of Waymo cars that have spinning lidar things all over them. I bet they are 1000x as powerful as that tiny ST brick.

.

I bet that lidar unit meets the same eye safety requirements as for an ordinary laser pointer or fiber optic IR communications laser. Otherwise, ST would have to jump through impossible hoops.

Looked at the VL53L4CX datasheet. See Chapter 8 (Laser safety considerations): IEC 60825-1:2014 (third edition). Meets Class I safety, which means no restrictions, even without eye protection.

I wonder if it's pulsed. It has picosecond distance resolution so any laser pulses would have to be very short, hence low power.

Actually, I don't need to do that.

CooL part !

Mouser has them in stock. Same price as Digikey

The US is a less popular destination than it used to be. For most Europeans it isn't a great place to raise your kids, since the US education system now sucks as badly as the health care system. This wasn't true when I was young, but the current crop of gradate students and post-docs may still want to spend a year or so there to polish their English, but they really don't want to make careers there.

It used to. It no longer offers an attractive environment for intelligent people. John Larkin isn't all that intelligent, and he hasn't noticed.

LIDAR (all caps acronym) is harmless. A laser pointer, at a mere few milliwatts, however, can cause retinal damage. You obviously have only a cursory grasp of the situation.

Yes, class 1. It meets that, however, a simple class 1 laser pointer is dangerous if one looks directly at the beam.

LIDAR is a pulsed fanning. A laser pointer is a focused beam.

Both class one, but the latter is dangerous.
