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.

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.

No. Never. It takes whole teams of people to get it right. (Even then, they sometimes get it wrong.)

That’s a false dichotomy if I’ve ever heard one, dude.

No, just follow the money. It’s all going into marketing. Ban marketing (like the rest of the world!) and prices drop overnight.

There is exactly one easiest option: be like the rest of the civilized world and ban consumer marketing of medicine. HUGE amounts of the prices of drugs are just down to TV ads. “Ask your doctor about…” is horse shit, let your doctor decide what prescription drugs you need. And fire the cocaine-riddled, law-breaking marketing departments that soak up so much money.

“Our recipes are consistent, like a good espresso maker.”

“Okay cool, how do you know that?”

“So many questions! We’re hackers! We are very smart.”

That’s the thing. They have no way of even knowing if they messed up! I’m not even sure the way they could be messing up is a thing they know they should be worried about.

I’m not disputing the reasoning behind why this is important. But “it is important” does not imply that their solution is the right one.

People make illicit drugs chock full of impurities all the time too, and it fucks people up.

There are standards for purity on pharmaceuticals. Impurities have to be ridiculously low. Lower than you can measure in your garage.

These dudes either don’t know you need to even measure purity or have decided that it’s inconvenient and are ignoring it.

I’m a process chemist. I do this sort of thing for a living.

These guys don’t even know why what they’re suggesting is so dangerous. Do not do any of this.

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!
