Re: Need tape for cell phone

Hi, I'm looking for tape for my friend's cell phone. The existing tape isn't sticking, and an internal connector that needs to be taped down periodically comes loose. The tape itself looks like some sort of foil/cloth tape, but isn't just foil tape or cloth tape, at least anything that I've seen. D...

False! :P No one's saying there's some weird dichotomy between using the power plant to generate power or somehow build another one. That's a strawman.

That is the sunk cost fallicy -- if we already built it, the cost of the already built thing shouldn't factor into our decisions. But that isn't what I am arguing.

If you build your own systems I think an SSD would be a solid investment. Swap it out of your old system and drop it in your new one. Your processor is fine, so IMO you should just upgrade GPUs periodically. That's where the biggest gaming bottleneck will be, even if it isn't there now.

It seems to be fairly basic structural engineering, so I don't see why it would be left out. I don't know if it would significantly change the maximum acceleration at which the plant could safely shut down, but fission reactors aren't the kind of things we want to cut corners with.
