...and on another hand we can love this planet by making decisions based on emotion rather than facts.

I find this deeply troubling (no pun intended).

Yes. The air in the container can escape through small leaks in the gaskets. Life vests cannot.

Maybe it's Gentoo.

As I understand it, this sort of activity doesn't cause earthquakes per se. Rather it catalyzes the release of existing pent-up geological stress. Assuming that's the case, isn't this actually a good thing? The energy stored in the stressed tectonic plates is bound to be released eventually, and isn't a series of small earthquakes far less destructive than a single big quake?

The parent's link refers to issues stemming from data not being reliably overwritten on a wear-leveling device. Why wouldn't those same concerns apply to any device that transparently remaps bad sectors to a reserved area of the disk? I understand that most writes to an SSD are wear-leveled, and I assume that transparent remapping of sectors on a magnetic HDD are relatively rare, but isn't information security supposed to be based on the worst-case scenario?

I can't comment about the availability of iPhone apps, but on both my old Palm Treo and my current Droid, I have a fully functional emulator of the legendary HP 48G/GX running a free ROM dump from the original calculator (with HP's permission, no less).

Apart from tests (where cell phone use is rightfully banned), I can't see much use for dedicated calculator hardware, but there's still a considerable need for portable math-machines.

To phrase that as a car analogy, 4 trucks driving at 60 mph is not the same as 1 truck driving at 240 mph, although there are some situations in which the output would be similar.
