What's wrong with Rust's error-handling mechanism (namely, the `Result` type)? Generally when writing Rust, panics only come up when you actively invite them with something like an `.unwrap()` call or the `try!` macro, which is Decidedly Bad Style for anything serious.
Sounds like it really wants to differentiate itself from the "old kind of socialism", which has a heritage of thought which already contains a lot of the things mentioned here.
And, as with most socialist thought, tends to kick up a lot of cries and moans from the self-professed economists in the room.
I was furious when I bought a Nexus 7 (first version) and found out that tethering wasn't available on the device (although there was no obvious reason it shouldn't be and rooting the device would have allowed me to enable it). Running into this on stock devices seems absurd.
This is cool, and I'm a sucker for gravity/space simulators (as my hours logged on Celestia would prove), but it should be noted that in terms of "galaxy" it's inaccurate. Specifically, this inaccuracy (the galaxy rotation problem) is the driving force behind the hypothesis of dark matter [0].
I don't mean to be pedantic or anything. I just think it's interesting.
AFAICT the rotation problem stems in large part from trying to use Keplers laws for a galaxy where they simply do not apply. I've even seen this problem in an article in Nature. It's quite a bit more than a 2-body problem. I'm in favor of these simulators plotting the rotation curves of simulated galaxies.
