Earlier quoted context omitted.

It’s in the link at the bottom of the “What is the Google CTF?” section.

Ah, I actually followed that link trying to find out. All i see on my browser is a bit of text with a big blue button that says "will you capture the flag?", which isn't really helpful, which takes me back to...the original website. Now on the one hand I'd say, ok, its not google's responsibility to try to have websites/non-standard browser configs set ups actually work with their web pages... On the other hand, I'm…

Quebec is always banned in most online competitions with a prize (I believe you can participate in Codejam for cannot win any prize), because local law forces these competition to be both in French and English. If it's not bilingual, they're not allowed.

I did. Its not a big page. There's nothing there.

Now I'm not a (total) idiot, obviously I can debug it if i have to (and if other people are telling me "there's stuff there, you just can't see it").

If i open it in chrome with extensions turned off or a default mobile browser, stuff now appears, so yeah, its got to do with script permissions and the like.

But again, why not just include actual text in the "what is google ctf" section that answers "what is google ctf?", and/or in the beginner's section that explains what's going on, and of all the groups of people you'd build your webpage for, are security people the ones that you want a website that breaks if they block your default scripts/permissions?

I'm lost on the beginners task. These things always make me feel stupid.

yeah, the beginner one is definitely higher level that I would've expected a beginner level one to be. Definitely starting with a binary/reversing challenge is already quite a bit more than I'd expected from the very first beginner level.

Dig at Apple from the third stage of the beginners' quest;

"Your first thought is "Why does the display stand need to announce its price? And exactly how much does 999 dollars convert to in Xenonivian Bucklets?"

You really don't need to reverse the binary to pass that one haha. The string isn't obfuscated in the ELF, you can just look at the file in a text editor to see the flag

It's running `strings` on the binary :P
