Comment Re:Electric Universe (Score 1) 225

Dark energy is needed to explain the rapid inflation of the universe. Dark matter is matter we know is out there but can't yet identify because it so weakly interacts with normal matter. One is extremely important to explaining big bang cosmology as we currently understand it. The other in certainly is part of the big bang story, but is as much an interest to particle physicist as cosmologists because it represents the possibility of physics beyond the Standard Model.

If someone were to come up with a ARM-based board with at least the capability of three or four NICs and a WiFi access, and could run a decent distro like Debian, even if it cost a couple of hundred bucks, I'd snap up three right now. I've built Linux-based routers/VPN appliances using Debian, iptables and OpenVPN, and I can't complain, but they still suck a lot of electricity, and quite frankly, are rather large. I have three Asus RT-N12 routers with TomatoOS on them, and they work great but I've never been able to get the onboard ethernet switch to reliably work as two routed network segments, and they are getting a bit long in the tooth WiFi-wise.

From an executable (if I can use the word for byte code) point of view, yes Java is the most portable. I compile once, run in many places. That doesn't really apply to Android or iOS, of course, but since I don't write mobile apps, I don't fret. But I do write apps that run on Windows boxes, Macs and *nix machines, and, as I said, as long as I'm careful to keep things version and platform neutral, my jar file can run on all these platforms. Code portability and executable portability are two different things.
