People in California heat with wood in the winter and air quality is also bad in the winter, this isn't the same...

There are commonly sold flammable refrigerant things now in the USA, I see a bunch of small fridges using alkanes and cycloalkanes, not sure about HVAC.

if you have a good butcher they might be able to get you some that you can render, but its a hassle. I've done this for beef fat to make some british pie things.

Its somewhat ironic.

I think there are a few eras. Pre-graphics, then pre-Google search, then pre-social media/public facebook.

I was young (got the transfusion just after I was born) but I understand that my parents got notified of the possible/likely infection based on that batch of blood leading to other infected patients, then I got tested and was positive.

You take antivirals orally. There is no vaccine that I'm aware of. I got Hep C from a blood transfusion in the 80s and waited decades without symptoms for modern antivirals before finally getting treated.

Overall, I agree, when I ask things I'm an expert in and do professionally every day. I get very good useful answers. When, for example, our marketing people, ask about the science, they often get confusing and wrong answers.

As long as there is money people will come just for that. That's where we got tech bros, like finance bros, instead of just a bunch of nerds making cool stuff.

Durable goods also seem much less durable. I go through way more fridges, dishwashers, etc then previously.

I just bought a 1 year old iPhone 16 on Facebook marketplace for $400. You can find pretty good prices if you don't need the latest device.

yes, DMF has a much higher boiling point. Its much more polar.

I've always heard of using nitromethane to remove super glue...

I wonder why Chloroethane / ethyl chloride was chosen. I don't think I've ever seen this for anything, other than a synthesis precursor to useful stuff.

Yes, the AI models are so useful in areas where you are an expert and can guide it in a useful way. I use multiple chats delay to help figure out client projects.

I suspect eutectic liquid InGa alloys would work, they stop wetting the glass when you are under vacuum. Although mercury is safe in the tube, just don't break the glass.

Robot characters keep you away from uncanny valley of creepy slightly off AI humans. Still fun though.

You could actually move very large quantities of water around and probably have a measurable impact. Like draining the California central valley aquifer.

At my previous job we made >1m wide 8um thick copper foil by electroplating it onto a giant titanium drum from blue copper sulfate solution. It was quite impressive.

But there are 100+ items for other people on the route on each delivery truck each day. So maybe better than individuals driving to the store. If you don't drive to the store that will for sure be better but thats abnormal in america.

There is a legitimate concern with space junk hitting useful stuff or even manned spacecraft but I think space is big and the sky won't appear bright soon. Not all satellites are that reflective and they need to reflect the sun, they d

Mine were like this is 2005. The math classes also didn't allow calculators, engineering classes did, but not graphing ones that could store information.

There are things like this: https://www.adafruit.com/product/5501 haven't used it, trying to find one for my mini pc, mostly so I can use a usb c power bank as a tiny DC ups.

If you are in the US then you can go to a hot place in the south west, even Eastern WA/OR or the California central valley when its >105F outside the wind blows and it feels like a hair drier or opening the oven, its not a cool bree

That's not always siloxanes, just atmospheric hydrocarbons.

Yes, you would also audit the quality system for your suppliers to confirm they are sufficiently controlling for upstream changes. In theory you can have all your ducks in a row.

In medical device manufacturing you have systems in place that your vendors have to disclose changes to their manufacturing process that hopefully can catch stuff like this before people die. I can see how minute stuff gets easily passed of
