# Google's Mysterious Billboard

Google apparently is behind this mysterious billboard that presents a nice number theory problem. I love number theory!

Of course, I could have written a program to sift through the digits of e to find the answer to this question, but I’m a pragmatic soul and figure why not just use Google since it’s 3 AM and I’m tired (I know, it’s cheating, but how good Google fault you for using Google?) The answer to this problem is also a website (7427466391) which presents a more challenging problem.

Congratulations. You’ve made it to level 2. Go to www.Linux.org and enter Bobsyouruncle as the login and the answer to this equation as the password.

``````    f(1)= 7182818284
f(2)= 8182845904
f(3)= 8747135266
f(4)= 7427466391
f(5)= __________
``````

Keeping in theme with Google’s love affair for the number e, I soon realized (by looking at this site that displays the first 2 million digits of e) that each of these numbers are consecutive 10 digit sequences of e.

I’ll give you a hint, if you sum the digits of each number (something I typically do to see if the numbers are divisible by 3), youll find an interesting result (other than they arent divisible by 3). That should lead you to the final answer with a bit of coding.

The final answer takes you to a recruiting page. What an ingenious and clever way to recruit talent, though I suppose by giving away the answer, I’ve defeated the purpose. How naughty!

very nice. im not much of a programmer, but i can see what it is looking for.

Well the site is down now. So tough luck getting a job.
But the first dozen or so people that got there probably are eating free catered food now.

Google will disappear like all hyped things do in time.
If they do not change what they are with the times.
I do not think everything Google does is likely within the law.
As Lewis Black said if a company cant explain what it does in one paragraph it is likely illegal.

Pretty cool. Google is pretty crazy as far as their hiring practices go. I have a friend who works for them down in Atlanta. Also the company I work for has a big project that Google is partnering with us on. Even though we did all the preliminary coding on the project now that we are working with Google on this you can only work on it if you pass all of Google's tests. And let me tell you these aren't easy tests at all. They are really really tough.

I'm an aspiring programmer and I'm disappointed the site is already down. I wanted to know what Google would have to say.

Wonder if any of you fucknuts noticed the original posting was in 2004. Code on brightboys.

Looks like these are the first five sets of rolling ten digits which add to 49. Thus, the next combo should be
5966290435 . . .way the heck down further. The linux.org logon has been removed. If I'm wrong you can simply email me at chris@christune.com

google is giving you gym, massage chairs, saloon, indoor games, music, cafeteria and other such facilities.. I wonder when do they work? do they spend 24/7 at googleplex? come on, are they hiring an engineer or buying a slave for their company?
