Comment Re:What if... (Score 1) 136

I was thinking exactly the opposite - It seems to me that certain types of creative tasks simply do not lend themselves to lots of iteration and refinement... Writing, for example, tends to get worse the more people mess with it. I'm guessing that movie scripts are the same. Obviously there's room for improvement on most kinds of projects, but I just don't see how you do iteration on writing a story or building a jet engine... at least not iteration in the sense of progressive refinement and adding features as in the agile software sense.

I don't know how LinkedIn's login APIs work, but if they use secure user/pass logins and store authentication tokens on the client side as is good practice then in theory exposing these server side generated hashes wouldn't really compromise the system. The problem is that SHA-1 has been broken :( So in theory someone could reverse these and get plaintext passwords and salts or whatever is in them.

This is one reason you don't send password hashes over the network...

Comment Wrong options... (Score 1) 239

I think you are describing those options incorrectly for his case.

--inplace is the opposite of what he wants. As I understand it --inplace will defeat some of the automatic duplicate range detection and save *space on the server* by not duplicating data during transfer. This does not help with network bandwidth but *hurt*. He probably doesn't care about space on the server, he wants his files mirrored quickly.

--update won't hurt him here, but it's probably not necessary as you seem to be describing it backwards. If he just mods files on his laptop and rsyncs the newer files on the laptop will of course get transferred. The only reason to use --update would be if he modded files on the server at home *and* on the laptop and preferred to keep the ones at home.

A simpler explanation is that waves oscillating perpendicular to one another cannot interfere with each other at all. The x axis oscillates at full magnitude, and the y axis does too, regardless of the relative phases. The only thing that's weird here is that the third filter at 45 degrees can "remove" the 90 degree difference in polarization, but it's not that hard to understand, and can be demonstrated with a much simpler experiment by just inserting the 45 degree polarizer between the ones at 0 and 90 degrees. Bonus nitpick: current polarized 3d glasses filter circular polarized light, not linear. If you add two of those together, you'll get linearly polarized light, the angle of which depends on the relative phases. I think (I haven't tried this so I'm not sure) if you put your RealD lenses on the two slits, you would not see interference patterns with the naked eye, but you would if you looked at the screen through a linear polarizing filter.

Comment No surprise at all. (Score 2) 200

Anyone who has rats can tell you that they're a whole lot more intelligent and advanced than the stereotype of rats would indicate.

But in more scientific terms, looking at other mammals, we find that... surprise, surprise... their brains are a lot like ours, and they have very similar capabilities, including emotions and feelings, as ours. They do not have them to the same extent as ours, but they do have them. Those are backed up by psychological observations, by anatomical/structural investigations, and by brain scans.

... I've been hearing this sort of claim for at least a decade. At first I got excited, but now, I take the position of "Wake me up if it ever happens."

Seeing how much people will pay to hunt certain exotic species already, I imagine that you could make terrific money owning your own private mammoth preserve.

Comment Disneyland already does this (in a small way)... (Score 1) 357

Some of the rides at Disneyland have started taking advantage of this idea by moving the passengers along on a moving beltway (kind of like at the airport) next to the ride... So you board the ride without the ride having to slow down at all... e.g. the Buzz Lightyear ride does this and I recall that it worked pretty well.

Comment Re:Proper branch testing (Score 2) 58

That was something that surprised me, too... for example, he says that it ran with a known bug in the routine for traversing diagonal lines, but that this particular maze design (or maybe just that particular run) didn't "tickle" the bug.

In some areas, he takes a rather simplistic approach to handling problems - in a good way. For instance, he says that turning fast makes the mouse lose traction and slide, his answer to that is just to start the turn sooner if the mouse is moving fast.
