I haven't been able to solve the puzzle - if there's any, however there is some interesting pattern in filenames. /staticfiles/svg/error.33ab1eb5.svg -> 33ab1eb5 hexadecimal is 866852533, which seems to be a prime number. I believe the probability is very low if unintended. Also other file names, can be factored more or less to 1 big prime number and few small primes.

These hex strings are beginnings of md5 checksums of these files: sh-4.3$ md5sum error.33ab1eb5.svg 33ab1eb5129ee5085793166d2f691dae error.33ab1eb5.svg I believe the point of appending them to the name is a kind of versioning: one'd want to be able to change these files and cause everyone to drop their cached version. This way when one changes a file, the filename changes too (most likely), so the cached old version…

Thanks for the explanation!

Have you ever seen the movie PI? You sound like Max, the main character.

I got a little further. If you append /login to the url, you get another script: Points to: https://foobar.withgoogle.com/_ah/logout?continue=https://ww... I've tried some ways to login to appengine etc but didn't work. https://appengine.google.com/_ah/logout?continue=https://foo... I've managed to get it to log me out of my google account. Not sure what's up.

I got one like this. https://appengine.google.com/_ah/conflogin?continue=https://... Throws a 500 error.

Same thing. Got 500 error by messing with that url. Seems like the idea is to chain that together in a way to login before you login.

If you are as confused as I was this old HN thread might help: https://news.ycombinator.com/item?id=8588080

Also, there are a lot of rabbits.

There are many in this thread who would greatly appreciate tips on how to access the challenges. Any ideas?

I have search history disabled in my Google account settings. I guess that probably disables the login for me as well. I search for Python related stuff dozens of times a day.

You're correct.

It looks like they're using Django. You can configure it to add the md5 of static files to each name. [1]
