No, but you will need the CS degree to be a good programmer. If you know what is going on under the hood you can avoid those O(N^5) operations that make your code inefficient. If you just blindly use whatever looks vaguely correct in the standard library you'll never know why your code is so slow.

Comment It just makes the router worse. (Score 3, Informative) 207

The description makes it sound like they just cut the Tx power on the router by two thirds when you enable the mode, which means it will just have a much shorter range. Even better: This would only help if the woman stayed near the router, she's going to get a lot more "radiation" from her laptop, since it has a similar radio and of course is much closer to her. Even if the science were sound, this wouldn't work. It's both dumb and pointless.

Comment Re:This is why I gave up PC gaming (Score 4, Insightful) 103

You don't need to buy this card if you're happy gaming at console resolutions. Even 6 year old midrange cards can push modern games just fine if you're willing to accept 720p at 30hz. You can even hook up the controller to your PC if you hate the easy precision of a mouse.

The problem with orbital mining is that it depends on the presence of orbital manufacturing. And orbital manufacturing depends on the existence of raw material. There is a chicken and egg problem unless you're willing to try to safely deorbit many tons of material every year, which is a terrifying prospect. It doesn't really make sense until we're building some sort of enormous space station or space ship in orbit and the launch costs exceed the eye popping costs of starting up an orbital mining/refining/manufacturing industry.

Anybody who moves between networks, like a cell phone? You still do route aggregation in IPv6, so even if your host ID (lower 64 bits of the address) don't change, the network ID (upper 64 bits) will when you move between networks. Otherwise you would need to propagate every single device in the world into the global routing table, and that doesn't scale.

Kind of true. Router autodiscovery works, but has some problems. It doesn't provide DNS information to the clients, nor does it allow the clients to populate their hostnames in the local DNS the way a DHCP server does. This makes it far from ideal when you want to allow for client to client communications. It also lacks any sort of authentication mechanism which makes it vulnerable to spoofing attacks. Router autodiscovery is a really incomplete solution.
