Maybe I'm an ignoramus, but what's wrong with storing your credit card number in a cookie, as long as it's encrypted? This is how session management is typically done, right? Your session information is stored encrypted in a cookie so that

Personally, I spend so much time in the shell that it's definitely worth spending some effort to increase my ability to use it productively. I switched from tcsh to bash about a year ago after decades of using tcsh. Switching to bash was a

If we are going to experiment with completely unproven political and economic systems on our own society, I vote for a socialist anarchy. First order of business: eliminate corporations. Immortal amoral virtual people cause nothing but trou

by nessus42 14y ago
Hmm, that's actually very interesting, but it sounds like it was much closer to a socialist anarchy, rather than libertarian capitalism.

Get back to me when you can point out a single successful country in the entire history of the world that actually operated on "Libertarian" or "Objectivist" principles.

So, in other words, Android will bring us all the downsides of a monopoly without many of its benefits? Look, Windows was/is a strong monopoly, and yet it ceded most of the hardware decisions to manufacturers, who also add all sorts of bloa

An Android monopoly certainly means something . I guess time will tell whether what it turns out to mean is significantly less onerous than other monopolies.

Amazon is not going to wrest control of Android away from Google.

by nessus42 14y ago
You make it sound as if there's any doubt that Google will continue to control Android for the foreseeable future. There is none.

You might be able to cook up something, but I doubt that it will be any more plausible than positing a preferred reference frame. Personally, I think that supporters of FTL should stick with subspace and run with it. And, hey, the author of

by nessus42 14y ago
FTL devices don't have to "criss-cross" for you to be able to create causal loops. And even if you don't have any causal loops, other violations of causality violate thermodynamics. It's not as if if you've solved the problem of causal loop

Squelching all humor, on the other hand, is not a way to keep a community healthy. This just makes it seem humorless and unwelcoming.

Special Relativity is not invalidated by GR: Special Relativity is a special case of GR that tells us what to expect in inertial frames in a flat space. As long as points A and B are in a flat enough space, then the predictions of Special R

And what happens if you try to make a loop? Do you think it sensible that the universe provide you with the ability to make causal loops and then somehow forbids you from actually making them, even though once you've been given the ab

by nessus42 14y ago
Special Relativity only applies if the space between A and B is relativity flat. As long as space is flat in the vicinity, then the predictions of Special Relativity hold true. It doesn't matter if you made some weird topological wormhole t

My reasoning is not flawed. And the paper you pointed me on re tachyons, specifically states that we cannot use tachyons to transmit information via them. I never stated that nothing can travel faster than light. Only that WE cannot travel

by nessus42 14y ago
But you can't use them to transmit information at FTL speeds without violating causality.
