Pinckney··on A Backyard Fight Club as an Alternative to Gun Violence
Imagine your startup is unwelcome at VC events because you're considered a coward after declining a duel. Or if you're an employee, you're passed up for promotions on the same basis.

You can think it bogus all you want, but that is small comfort if there are concrete socially-enforced ramifications for declining a duel.

Pinckney··on NASA official warns private sector: We’re moving on from low-Earth orbit
Not yet, but perhaps in the near future. The National Space Society has a proposal up for capturing 99942 Apophis via gravitational slingshot, which would be fairly damaging if we managed to crash it.
Pinckney··on NASA official warns private sector: We’re moving on from low-Earth orbit
No. Any asteroid we could reasonably capture is much too small to have any significant impact.
Pinckney··on The Cannons on the B-29 Bomber
Kill claims are notoriously overestimated during this period, frequently by ratios of 5:1 or more. The only reliable way to estimate kills is to look at enemy records and see how many aircraft were recorded as lost during a given period.

Take a look at some of the entries here; April 17th stands out.

"the 91st and 306th Bomb Groups claimed 63 German fighters destroyed, plus 15 probable and 17 damaged. Only two were confirmed destroyed, with nine damaged."

Pinckney··on Why There's Still Not a Human on Mars
De Gama and Magellan actually had a reason for their expeditions, namely, making shitloads of money in trade.

Let me know when Mars ceases to be anything but a colossal gravity well for us to throw money into.

Pinckney··on Smart guns finally poised to change U.S. gun market?
The iP1 which nearly went on sale last year was going to be sold for $1800 with the watch, and was only available in .22lr.

AFAIK, nobody has posted dissassembly pictures or video yet, but I would be surprised if the electronic disconnect can't be easily removed by anyone with time to field strip it.

Pinckney··on A lot of what we think we know about WWII is wrong
"Panzer" just means "armor", and was the label used for all German tanks. Everything from the tiny Panzer I to the Panzer VI Tiger. Presumably you're thinking of the Panzer IV? But only about 8000 were built, of which only about 6000 were the long-barreled version which could match the Sherman.
Pinckney··on A lot of what we think we know about WWII is wrong
Panzer is just the German generic term for tank (or more literally, "armor".) Everything from the tiny, machine-gun armed Panzer I, to the Panzer VI Tiger.

The standard, 75mm Sherman was roughly equal to the long-barreled Panzer IV (~6000 built).

Pinckney··on It’s completely ridiculous to think that humans could live on Mars
You'll need to cite sources for Chicxulub or any other impact producing temperatures like that globally.

It is thought that Chicxulub may have produced global firestorms, before a period of global cooling. The point still stands: it's not hard to build structures that can survive fire. Building out of concrete, with thick walls, a self-contained air supply, and away from any vegetation (or simply underground) should suffice, and will still be much easier than colonizing Mars.

Pinckney··on It’s completely ridiculous to think that humans could live on Mars
The threat from asteroids is that years of perpetual winter shut down our agriculture for years or even decades. But even in the case of a really massive, Chicxulub sized impact, earth will remain more hospitable than mars. The temperatures will be milder, sunlight at the surface will still be stronger, the air will still be breathable.

If we can build a sealed habitat on mars capable of recycling water and growing its own food, we can do the same here on earth. Just give it a dedicated fission reactor to keep the greenhouses running, distribute half a dozen of them around the world so that they can't all die to direct impacts, and fortify them heavily to keep the starving masses out.

Pinckney··on The Okinawa missiles of October 1962
What sort of covert op? Who would want to start WWIII?

But consider survivorship bias.
Pinckney··on Math professor forced to use $180 textbook written by his boss
I graduated four years ago, and am currently in grad school.

As an undergraduate at a small private college, I can only recall two professors who required their own books. One was a paperback physics reader for a very large class, available from the department for $20 (or from upperclassmen for less). The other was for a small math class, was not unreasonably expensive, but also was not very good, but when the professor left halfway through the semester with health problems, the department bought us all copies of the new book. My professors were always accommodating to anyone who wanted to buy an older edition, and in one case explicitly told us not to buy the expensive new edition.

In my current department at a large public university, I know of only one professor who requires his own book. It's about $40 and has only had one edition since it was published 15 years ago. In most lower division classes we use an in-house online homework system, although we don't have a good database of problems for differential equations, so we've typically required the latest edition of Boyce and DiPrima so students can use the publisher's homework system. But we've started work on our own problem sets, and we are at the point where we can use our own in-house homework system for it, if the professor is willing to put in a bit more effort organizing and debugging homework.

Anyway, this sort of exploitation is not typical in my experience.

Pinckney··on Google employee lives in a truck in the company's parking lot
A truck is stealthy. It doesn't necessarily look like anyone is living there, which means you're much less likely to be hassled by the police. Compare carcamper's experiences below.

He mentions on his blog that he already had a run-in with company security. The verified that he was an employee, apologized for waking him up, and left him be.

Reminds me of this account of ditching during a ferry flight to Hawaii:

Pinckney··on How Will We Get Off Mars?
"The continuation and survival of the human race is the top priority among a large population of people. Some contribute by researching new medicines (Why do this?), others improve quality of life for others (Why do this?), others have children (Why do this?), and others look for a way to get us away from a potentially doomed planet in case of disaster scenarios."

The vast majority of medical research goes to diseases that pose no existential threat to Homo Sapiens. Even Malaria, which kills upwards of 500,000/yr, does not pose any existential threat. Late-life diseases such as alzheimers have no effect whatsoever on Homo Sapiens, yet receive substantial funding. No, medical research largely serves to decrease human suffering, a goal which I do regard as noble.

Likewise, why does increasing quality of life matter? Humans will continue to reproduce even in conditions of abject poverty. What does quality of life have to do with anything? (You, after all, seem to think putting humans in a thin metal tube and hurling them through space to live out their life on a cold, barren rock is important. Surely you don't think this would increase their quality of life).

As for children, I have no clue what people see in them. But they seem to reproduce because having children makes them happy, not out of some perceived obligation to Homo Sapiens.

My point isn't that you need to share my morals. My point is that you should acknowledge your morals are not universal.

Pinckney··on How Will We Get Off Mars?
And this should affect my behavior why?

If I cared about perpetuating my DNA, I'd donate to sperm banks to produce more genetic offspring than I have any hope of supporting on my own. From the Darwinian perspective, I would be regarded as enormously successful.

Pinckney··on How Will We Get Off Mars?
Why is the perpetuation of Homo Sapiens a moral imperative?
Pinckney··on Volkswagen Emissions Investigation Zeroes in on Two Engineers
In warfare. A commander can be criminally liable for failing to prevent criminal actions by their subordinates. Most famously, Tomoyuki Yamashita. Or from the prosecution brief during Ernest Medina's trial:

>'When troops commit massacres and atrocities against the civilian population of occupied territory or against prisoners of war, the responsibility may rest not only with the actual perpetrators but also with the commander. Such a responsibility arises directly when the acts in question have been committed in pursuance of an order of the commander concerned. The commander is also responsible if he has actual knowledge, or should have knowledge, through reports received by h'un or through other means, that troops or other persons subject to his control are about to commit or have committed a war crime and he fails to take the necessary and reasonable steps to insure compliance with the law of war or to punish violators thereof.'

What do you think the weigh stations are for?
Pinckney··on Sandra Bland arrest video has continuity problems, anomalies
I'm not asking why they might want to tamper with evidence. The motive for doing so is obvious. I'm asking why, if they did decide to tamper with evidence, did they do such a bad job of it? If they were already editing the video, why didn't they make their edits at times where they wouldn't be obvious?
Pinckney··on Sandra Bland arrest video has continuity problems, anomalies
I watched the video too.

If someone edited the video, why did they choose to make their cuts at times where cars or people are in scene? They would have gone unnoticed had they occurred a few seconds earlier. Who would be so stupid?

Pinckney··on What is the most ridiculous aircraft design?
No it isn't. It's just an artist's fantasy. It has no more basis in history than the Nazi flying saucer depicted in the other renders of the set.
Pinckney··on What is the most ridiculous aircraft design?
They had to be disconnected, reconnected, and recalibrated every time the nose was opened and shut.

Pinckney··on What is the most ridiculous aircraft design?
And for some reason, anyone who posts anything about it online seems obligated to put it alongside those stupid battleship hybrid renderings.
Pinckney··on Same-Sex Marriage Is a Right, Supreme Court Rules
Public accommodations are not prohibited from discriminating on the basis of sex by federal law.

Furthermore, the bakery is probably not a public accommodation under federal law unless it's principally selling food for consumption on the premises.

Pinckney··on Same-Sex Marriage Is a Right, Supreme Court Rules
States have existed far longer. "Nation state" refers specifically to a state which coincides with a cultural or ethnic group. If you had to choose a starting point for the idea of the nation state, the Treaty of Westphalia is one of the more reasonable.
