Right, we know that it's not a huge problem because not that many planes are crashing.

Also, I suspect that circuit checks could detect at least some shorts in wiring that can't be physically inspected.

This is a fake, sure. Maybe it's not perfect, but the software is improving. So within a few years, I'm guessing that fakes will be indistinguishable from true recordings.

But this was based on the text of an actual speech written for President Nixen, to be delivered if the mission failed. So isn't it likely that he practiced it, just in case? And if he did, it might have been recorded, more or less accidentally. As Reagan's quip about nuking Russia was.

And so as others note, it becomes crucial to look at the historical context.

Yeah, this ought to be the top thread ;)

A few careers ago, some agribusiness dude asked me why I opposed the introduction of nonnative species, given that I was concerned about biodiversity loss.

As I understand it, decomposition of ammonium nitrate (NH4NO3) alone produces a mixture of ammonia (NH3), nitric acid (HNO3), nitrogen dioxide (NO2), nitrous oxide (N2O), and water (H2O). But if there's a reducing agent around, such as charcoal, coal or fuel oil, you'll get lots of diatomic nitrogen.

> They do need an oxidiser though.

When lead azide detonates, you get elemental lead and diatomic nitrogen. So yes, the Pb++ oxidizes the azide.

When acetylene detonates, you get a mixture of organic compounds. But I don't believe that there's any redox involved. You just get various hydrocarbons with single and double carbon-carbon bonds. And just to be clear, this is when there's no oxidizing agent present.

And if you're "inside" an explosion that's too slow to generate a shock wave, you may not even be seriously injured.[0] At least, if the pressure spike is too low to rupture your body. And as long as objects don't get accelerated toward you.

As a child, a friend and I were electrolyzing water, in an enclosed space. And so the hydrogen flashed. But the concentration was so low that the air just turned faint blue. There was no damage, to us or the building.

> In an explosion, however, the devilish little instigator that is oxygen shoves the process into overdrive.

It's a great article, and I know that I'm being pedantic, but chemical explosions need not involve oxygen. For example, consider acetylene and silver acetylide, with a carbon-carbon triple bond. Or lead azide, with a nitrogen-nitrogen triple bond.

I've always used line-interactive aka double-conversion UPS. Both because of the battery failure issue, and to protect equipment from crappy generator power. Basically there are rectifier and inverter circuits, with batteries on the DC side.

> Each of the 911's lighting units includes 84 individually controlled LEDs that allow the car to continuously morph the pattern of its beams. When a car approaches in the oncoming lane, the 911's headlights dim around it while leaving the rest of the pattern bright. The other driver doesn't get blinded, but you still have blazing lights on your side.

That is amazing. And I suspect that one could incorporate more autopilot technology. Perhaps to better illuminate pedestrians, bicyclists, motorcyclists, and wildlife. Also perhaps police vehicles, identified through markings and/or tag number.

I have eaten dried grasshoppers with beer. And actually, it's less gross than pork rinds ;)

I wonder if they're a workable source of psilocybin.

I wonder whether disposable credit cards protect against this.

Well, it does sound like a very useful service.

I wonder how they could have gone that far off the rails. Maybe they got taken over by investors, or acquired.

Right, I suspect that there was much more behind Bob's deep field study than TFA presents.
Sure. But in my experience, what works better is remembering happy times. Or rather, represencing happy states.

And once I'm being happy and optimistic, it's natural to persevere and accomplish stuff more effectively, and I have desired results. That is, "be -> do -> have". Which is just the opposite of the western cultural default of "have -> do -> be". As in: "If I were wealthy, I could do all this fun stuff, and then I'd be happy."

Yes, correlation <> causality.
Right. And furthermore, if they could be taken down, that's a bug, and it ought to be fixed. As I understand it, they're already somewhat decentralized, and it wouldn't be a huge stretch to become fully decentralized.

Yes, I get it. Those are not nice people. Few of us would want to be friends with them. Or even work in the same building. So have them work from home, or for a standalone subcontractor.

I also get the downside of employing them. But people need to look at that stuff, even if software does most of the work. So it might as well be people who can tolerate it, and perhaps even enjoy it.

Before that happens, I'm guessing that full DNA sequencing at birth will be a legal requirement. Like footprints are now.
I wonder how fast the flow cell price will drop. But even at $1000 I might be tempted, except that I'm so damn old, and never (as far as I know) had any kids.
Wow, that's better than I expected! So maybe a resale market could develop on Craigslist or whatever. Buy one, get your data, clean and wipe it thoroughly, and then resell it. Maybe the refurbished price would stabilize at $500 or whatever.
No, not really.

There's no practical way to protect our genomes in meatspace. We're constantly shedding DNA into the environment. Hair, skin, saliva, etc. For example, an adversary can just tail us to a coffee shop or restaurant, and take a utensil or straw or napkin that we've used. And then submit the sample using a fake name, as investigators often do.

Edit: Those are excellent comments about scale. But generally, if you don't want to publicize your genomic data, just don't send in a sample.

I wonder if there's some way to do testing on a walk-in basis, in a way that would allow transparency re the lack of sample and data retention.

So a customer walks in, provides a sample, and walks out with data on a thumb drive. And perhaps also with the module that was used for the analysis.

Why not, if they do the work well?

And anyway, they'd be working from home, these days.
