@cormullion Thanks! I found the option to change the user agent and it works!

comment Where can I find examples of good Mathematica programming practice?
@cormullion Got any tricks that work on Windows? I usually download videos from Youtube using a little program called Free Youtube Download. But that doesn't work on wolfram.com/broadcast (except for a few videos at wolfram.com/broadcast that are actually hosted on Youtube).

+1 @VitaliyKaurov. Luckily, the points of my data are sufficiently far from the boundary, but I can see how it can be an issue in general...

+1 Thanks for bringing the Lambert azimuthal projection to my attention. Very useful.

Is there a way to download the videos from wolfram.com/broadcast?

comment Resources for beautiful Mathematica Stylesheets
Perhaps this should be CW. I think that seeing this question with an accepted answer discourages any further contribution. Although by now it is established that currently there are no repositories out there, eventually there could be, and we should encourage their addition here.

comment Efficient backtracking with Mathematica
Thanks. In your experience, how much faster can C be compared to Mathematica when doing backtraking?

comment How do you check if there are any equal arguments(even sublist) in a list?
@Mr.Wizard I ran the tests you mention in the comments above and you're right. This is very slow (I had to kill the kernel!). And I thought it would be faster (by the rule of thumb that smaller code in Mathematica -> faster). Why is Union faster? I mean, it returns a sorted version of the list, while UnsameQ will stop comparing (I think) when it finds the first pair of equal elements. How can Union be faster??
