[Request] How thick would the walls of a hollow sphere need to be to not fracture from the detonation of 1 kilogram of C4 at its center?

The sphere is made of iron. And the inner diameter is 3 meters.

For funsies, the sphere is filled with either pure helium or pure xenon. Low density and high density.

Anyone have experience with Alabama Virtual Schools?

Our local school system is pretty bad once they get out of elementary school. We’re thinking about enrolling in virtual school but don’t see much of the pros and cons from families who participate.

Would you use a pump that can only be controlled through a smartphone?

Medtronic sales rep called me yesterday because my pump is coming up on the end of its warranty. They tried to get me interested in the Flex, a new pump that connects to a separate device to control it.

I don't know if I'm just getting grumpier in my old age, but I don't think a single thing about this new system is appealing to me.

  • I like being able to change a single AA battery when my pump needs it. A rechargeable, on-board battery is another thing that can fail.

  • The only point of control for the pump is through a smart phone app. I can't even get the Minimed Mobile app to send my data to my endo on time. Now Medtronic wants me to trust that its app connected to my life support system is going to work without fail?

  • What happens if you go to an event where phones are prohibited? You'll be stuck fighting with whoever is running security explaining that you have an ADA exclusion just so you can get in to your concert or whatever.

  • Phones get lost and stolen all the time. What happens then?

  • Will new software versions of the app require new FDA approvals?

It really just seems like that pump is a solution in search of a problem.

[iOS] Markdown formatting not working in app.

When I comment in the app, it’s automatically removing the markdown formatting.

Is supposed to look like

> this

But if I put that comment in the app, it doesn’t format it and adds a solidus to break the formatting.
