### Re: Portal 2

Some places in co-op that can be done slightly differently to the 'normal' way: In a room where you were meant to cover two walls in repulsion gel and bounce back and forth, I think I just jumped all the way up. There's the hard light room with the 5 portal achievement (chamber 3) with s...

### Re: Regexp to replace numbers outside of quotes

I don't know if it could be converted to sed, since it uses \G and look-aheads and such... also, sed by default reads through line by line, and this needs to be run across the entire file in one hit (otherwise triple-quotes are impossible to handle). sed actually has a fair amount of features that ...

### Re: Manufactoria - Make Turing Machines with Conveyor Belts

Sorry for posting an incorrect solution earlier. The G/Y branch was meant to be a square higher (directly below the R/B), so that after going through the middle section the yellow would put it back into the loop. An updated solution that should hopefully be correct this time. B/Rs are more numerous ...

Yesila wrote:the classic [imath]\int e^x \sin(x) \, dx[/imath] class of problems where you do some integration by parts (twice) and get back the original integral, do some algebra and solve for the integral

A simpler (less error-prone) approach would be to differentiate it twice.

### Re: Accuracy and Precision in Mathematica

As far as I know, having a decimal point will make Mathematica stop using exact values (assumption made from Wolfram Alpha and my TI-89). Compare, for example, sin(pi/10) and sin(pi*0.1) on Wolfram Alpha.

### Re: Balls and bags.

Yes you can: For example take one of each possibility (bold = dropped): W W W W W B W B B W B W B B B B - you then get W W W W B W W B following the rules, of which half have the second as white (the assumption that the dropped ball is random is due to the dropping being accidental) ...

Nope. Read the question more carefully. (You too, OP!)
