    If I have ever been exposed to it, my memory definitely removed it very well.

     

    Thanks for the link, very instructive!

     

     

    Edit: That was brilliant Charles

    It broke the CoffeeHouse for me Smiley

     

    I can only navigate to the last three threads via the menu on the right side Wink

    I tried 'April Fool' then gave up (ended up coming in via the forums link which was left open?)

    I don't know how to solve those formulas... Smiley

    I got it, but only by coincidence: I had a series of classes on lambda calculus last week and I recognised the Church encoding of the natural numbers as lambda functions (as contextfree said). Simply count the level of recursion to get the number, in this case it was 9-deep, so it represents '9'.

     

    I recognised the other question as product notation. Going by the frequent use of '3' and how 3*3 == 9 I figured the answer was the same.

     

    Note that I actually advocate implementing something similar to this as an actual captcha in future. Keep it just as difficult, I like the idea of there being a forum with just me on it Tongue Out

    The next captcha should be "Within the context of computational complexity theory, prove or disprove P=NP."

    Or you could bypass the filter and go directly into the topic via bing and find out the answer.   Smiley

    Yeah, I can't reach any of the forum pages due to this...

     

    The prompt comes up, then IE complains that it cant reach the website Sad

     

    I was able to go to the homepage and get into this thread from there.

    Component factory have something similar, you are asked

     

    Answer the question to prove you are not a spam bot, but a human.

    Binary number 1001 is what in decimal?

     

    or

     

    how many fingers on a human hand?

     

    Obviously Phil used to lurk around the channel 9 forums a lot so I wonder why the 1001 binary? The long and the short of it is spam in his fora is now almost non-existent, whereas it is a growing problem in the Sandquist fora. Look at the mix comments and here on channel 9, a lot of the posts are begining to get targeted more and more.

    Fun stuff.

     

    Please tell me that your little game didn't keep anybody from non-stop slaving away on Rev9?

    This is all I've been doing for months.

    Rev9 was an elaborate cover for this new feature.

    I got it on my first guess, like a real scientist  Tongue Out

     

    (Second guess was going to be 42).

    Bash the stop button, fill in 9, then no more worries
