I bought some 3D printing filament direct from the manufacturer. It got shipped to me by… Amazon. From an Amazon warehouse. I guess that’s how they do fulfillment. 🤷‍♂️

Not necessarily. A lot of podcasts are hosted by places that detect your ip and splice in location-targeted ads for each individual download. Hence OP’s struggle with timestamps.

Even off of Spotify etc, the source is poisoned.

DHH with a pants-on-head stupid argument just because he hates the big players in tech? Must be a day ending in Y again.

One even worse thing about smart tv’s - they come with a bunch of free “channels” you can watch. If you have streaming services or cable, who cares?

Except the people that don’t – rural folk who never would pay for cable – gobble it up. And it’s all right wing propaganda garbage. From Fox News to Newsmax, they’ve got every kind of anxiety-inducing conspiracy-laden “news” you can watch.

The crazy thing is that the Dutch (or the people who lived in what is now the Low Countries) were winning that war pretty handily until like eight thousand years ago. Then they lost Doggerland to the sea.

Their descendants remember, though. The Dutch will rise again.

I enjoy a good non-oversexualized depiction of Samus. She’s an absolute badass. But everyone just wants to drool at her skin tight blue suit.

Unless our ability to cram delta-V into a spacecraft goes way beyond what seems possible now with chemical rockets, a trip to the moon is always gonna involve a few days of coasting through space. That’s always going to take more preparation than a transatlantic flight.

I sort of feel bad about raining on the parade of the person distilling isopropanol in his garage earlier, but it really is dangerous.

But most of us chemists also need to be reminded of it. To the point that someone had to write a paper whose entire point is “don’t distill isopropanol”.

Please, don’t do this thing.

The issue with isopropanol peroxide formation is that exposing it to air – even when just using it, like when you’re cleaning parts – starts the process. The air in the head space of your containers is also enough to form them over time. You don’t necessarily need to see solids in the containers for it to be dangerous, since they’ll crystallize out as you concentrate the solution during distillation.

It’s also a numbers game. It probably won’t explode the first time you do it. But there’s a chance each time. Do it enough, and you’ll have an incident.

There are chemical reductants that can clear peroxides. For industrial scale isopropanol distillation, I’m not sure what they use. It may be that they just never distill down to the point that peroxides concentrate to a dangerous level.

I love EnF. But I assure you, organic peroxide formers are scarier.

No no no no no.

I’m a chemist. Organic chemistry PhD, now a process chemist in the industry. I do this for a living. Do not distill isopropanol that’s been exposed to air for any meaningful length of time.

Isopropanol slowly reacts with oxygen in the air to generate peroxides that, when you concentrate them down, EXPLODE. Source. Sorry, not an open access journal. But please take my word for it.

Unless you have a way of confirming the peroxide levels in your isopropanol are near zero, do not concentrate it down by distillation. You’ll blow up your glassware, which will probably expose what you’re distilling to your heat source, which will generate a secondary fireball.

PLEASE do not do this.

Shit guys, the tone police are here! Scatter!

Billionaire evil is a sliding scale from normal rich guy evil to comic book villain evil. He’s less bad than his peers, even if the stuff he does (like the cost plus drugs thing) are maybe just for PR.

We eat him later than others. But we do eat him.

Fuck off with this voter suppression shit

got lucky

That is not how I’d characterize 2016 at all. Also, I would like to refer you to argument number two.

Why on earth are we still listening to Nate Silver?

A lot of the Apollo work also got done in basically one administration (Johnson largely continued JFK’s policies). As soon as Nixon was in charge, NASA got gutted, and then they only had the resources for shuttle. Later Apollo missions got cancelled because Nixon thought the money was better spent killing more Vietnamese people.

Switching administrations means vastly changing policies, if for no other reason than the new boss hates the old boss. SLS “succeeded” (got hardware made and launched, at least) where Constellation failed partly because they buttered everyone’s bread in the right way.

HLS is dumb. SLS is dumb. But similarly to Commercial Cargo and Crew, it survived administration changes partly because NASA wasn’t directly at the helm, so the new guys didn’t just hit the big red stop button.

In the entire history of NASA, they’ve never manufactured any boosters for themselves. Redstone was from the army. Titan, also military. Saturn I and V were designed by NASA but contracted to big aircraft manufacturers as contractors. Shuttle was Boeing / Rockwell for the orbiter, ATK for the boosters. SLS is basically all the Shuttle contractors, again. (That was the point.)

I hear what you’re saying. But NASA would need to spin up an entire company from scratch to build their own rockets. That’s not what their mandate is, and it’s not what they’re good at.
