kale,

I’m a mech E in the medical field. We’re consistently understaffed. If I validate an Excel worksheet in Excel '08 or a Python program in 3.5 with a specific version of NumPy, we’re probably sticking with those versions for a while. Every time I bring up re-validating with the latest version, keeping one old system running the old software requires fewer resources than me or a colleague re-validating.

My whole department is stuck on one version of Python because that was the most recent version when I had an emergency project and developed a data analysis algorithm. We validated it, then as new members were added to my team, they needed a copy, so we had to keep using it. I’ll probably re-validate it to the next Python release. It’s not only unit tests, or we could automate validation. Unit tests are a tiny part of validating software for making medical decisions. And software that directly runs a medical device (like firmware on an insulin pump) is an order of magnitude more rigorous than what I do.

Side note: there are people who somehow root their insulin pumps and run algorithms on them. There’s a group that can get a PID control loop on an insulin pump that has a more simple control scheme on it (because that’s how the FDA approved it). The company has been trying to get approval to use PID control in the US for years.

kale,

Plastic is usually scratchy. Glass is much better about resisting scratches. I believe you’re, right, modem phone glass is pretty flexible. It’s also (usually) coated with something that prevents finger oils from building up easily.

kale,

Yeah. I know people who say stuff like that. I know someone who wanted a convertible car (they were 18). Someone mentioned the greater danger of they flip, and this person said “well I’m not going to flip a car”. We all gave them a hard time about whether they thought everyone who flipped a car did it on purpose. The next year, this same person flipped their car several times (and walked away OK somehow).

Some people can’t comprehend that bad stuff would happen to them.

kale,

Yeah, only the people who don’t flip their car should get one.

I have zero problems with owning one, and have owned them in the past. We knew this person was a crazy driver and that it was a bad idea.

In the American southeast, especially in a river Delta, you can’t live in a house long without AC or a dehumidifier. Mold will grow to toxic levels quickly in a house that’s left without electricity for very long in areas around me.

We have trouble opening our front door in the summer when the temp gets above 38 due to the humidity causing the wood door to swell. The heat index reached 47 last week due to the high humidity so there’s a ton of water in the air.

kale,

I’d make one exception: cotton wants to hold water. Evaporative cooling needs water to evaporate. There are synthetic materials that will hold much less water, so they’ll weigh less from sweat and evaporate more quickly, providing a tiny bit more cooling. Plus many have protection from the sun reducing the amount of sunscreen that has to be worn.

There are a line of shirts known as “fishing shirts” that are made to be big, and they have vents to encourage air to circulate inside them. They work great.
