Historically cable lacing was done with waxed cotton. Since WWII more nylon and polyester, as they wear harder and don't burn as good, don't like water, etc.

I'd imagine NASA uses some kind of space age stuff.. polyimide or some sort of fluoropolymer, but who knows, maybe cotton has better extreme cold weather performance.

CA still out-manufactures every other state. second place is texas, Though CA has a bigger population.

It's had some decline in manufacturing, sure, but it's never going to be like detroit. Hell, even if they quit making things entirely - CA will never be detroit, between IT, hollywood, tourism, service BS, etc.

That's kind of a bullshit complaint. Do you currently plug your phone into a USB A to USB B adaptor, to a USB B to USB mini B adaptor, which is plugged into a USB mini B to micro B adaptor? (yeah, I skipped some USB variants).

No? then shortly you'll just have a USB micro C cable / charger, same as how you have a micro B cable / charger now.

I know, one more USB connector to have an adaptor for... But this is how the mini/micro and even old USB 'A' should have been from the beginning.

There's nothing worse than having to blind mate USB, and having to flip it four bloody times before it works. (except maybe blind mating 'F' connectors, or sometimes D sub..)

Well, the Molex bit is kind of a stretch, to me. They make connectors for _everything_, not just aerospace. I'd imagine aerospace is a pretty small amount of their business?

Looks like molex runs about 10% of the global connector market. 70% of which they generate outside of the US. Kinda surprised me their share is that small.

I think defense and areospace use more connectors by Amphenol, or Cannon (now ITT). At least they did 40 years ago.

But when concrete sets, it does so via reabsorbing the CO2, right? So it should be a net neutral (minus CO2 from the fuel to cook the limestone in the first place).

CaCO3 + heat -> CaO + CO2 (in air)

Add water, get Ca(OH)2, which reacts with CO2 from air to set... back as CaCO3 and water..

Or did I miss something?
