wood chipper to make compost
I don't think it'd make good compost as pallet wood is heavily treated with chemicals to make it flame retardant and resistant to insects, molds and humidity. If you manage to burn some (with difficulty), it burns with weird colors and smells.
Survive an Earth asteroid strike for one.
Yeah and then what ? It's not like you can find raw material to rebuild civilization when you are suspended 20km up in the air...
Since you mention it I'd like to ask a question about the pictures in the movie. I saw the movie several times but could never figure out what is seen on the picture is actually zooms on, the one with the room and (?) mirror. I'm sure it's on some FAQ somewhere but never dug into that.
As to why there are more threads related to C++ on the Internet, easy, it's because C++ is a lot more complicated and complex to grok. I need as much help as I can with some of its tortured constructs and seldom used idioms. C is more straightforward (even if there are plenty of tricky things in it, which the seasoned programmers will either know how to use or steer well clear of).
