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

Thanks!
Where is that machine located?
I'll come over and post from there

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

There should be something like that everyday.

Erik just wanted us to watch his C9 lecture series again.
Nice.

I don't know how to solve those formulas...
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 9deep, 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

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.

Bravo, Charles!

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
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 nonexistent, 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.

I just solved it.

Fun stuff.
Please tell me that your little game didn't keep anybody from nonstop 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
(Second guess was going to be 42).

Cool and fun idea. First guessed 42 and then 9 =)

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