'Stone'? You mean 'brick'.

Lego's argument always struck me as absurd. Imagine Ford doing the same thing: "Please refer to our vehicles as 'Ford vehicles' or 'cars', and not 'Fords'. By doing so..."

That could hardly be farther from the truth.
The church does have extrabiblical volumes of scripture, which also testify of Christ and go into more depth, but every doctrine of the church is in harmony with the Old and New Testaments. Members believe it is only by faith in Christ and by good works that they can be saved.

They don't get wealthy from it.
Those who work for the church full time (with the exception of missionaries) receive a stipend to cover their living expenses and not much else.

boolean checkExactlyOneBitSet(int num) {
return (num & (num - 1)) == 0;
}
That looks like it'll fail when num == 0. I think it should be:
return num && ((num & (num - 1)) == 0);

From IMDB:
"The computer name WOPR used in the movie was a joke based on a real computer once used to predict war strategies at NORAD which was called "BRGR". The Burger King "Whopper" is a "Burger"."

The posted solution to fibonacci (in the rss image for this hn article) appears wrong. fib(0) will return 0 instead of 1.

icgrep (http://www.icgrep.com) has a clever approach to searching text for arbitrary sets of characters in a parallel manner. If 128-bit registers are available and we're processing 8-bit characters (for example), the next 128 characters from a file are first loaded into 8 SIMD registers. Then a bitwise transposition is performed so that r0 contains bit 0 of each input character, r1 contains bit 1, etc., up to r7. Then with a series of logic operations across those registers (imagine the sum-of-product result of a k-map of characters of interest), searches for any arbitrary subset of characters can be performed in parallel, leaving 1s in the corresponding position of the result register for each match and 0s elsewhere. icgrep supports full regex patterns and Unicode (using 21 registers instead of 8), but what interests me are the elegant transpose and logic steps.

How about a game to teach regex? That would be awesome. "Write a regex that will match xxx and yyy but not zzz", for example.

Couldn't this problem be simplified by considering the nodes and paths to be a resistor network, and solving for the effective resistance between the source and drain nodes?
