I think it's a great idea. I would rather a set of tutorials though. I don't want to email and waste somebody's time if I'm not able to commit to anything.

You're only wasting cpu cycles ... you're emailing a bot.

I see. In that case, why not just put the exercises online?

To get used to the kernel way of sending patches: email.

Gamification ... you need to "level up" to get new challenges.

Actually, it's processed by a script (a bot if you like), however, if something fails a person replies to you. This is the problem with many of the challengers. When everything is ok they proceed, when something fails[1] it might take weeks to get a reply.

[1]: failure might be because of a corner case or an implementation not working on a specific configuration.

The author _says_ that it's done by shell scripts, but in reality he's checking them by hand (i.e. in the coding tasks you get actual code review).

Since the page is not dated, I wanted to find out whether the challenge has just been released currently or not.

I'm running through these at the moment. Some challenges have really heavy queues (ie: Challenge 3 has an expected response time of 1 month at the moment. ~8000 challengers are participating out of an expected < 1000).

It's an interesting format.

I agree - I really like it and I'm learning a lot. However, i'm losing motivation due to the lengthy queue.

Task 6 currently has a two month wait. Given that you may have to submit multiple times to get feedback and fix mistakes, you're talking a significant part of a year to get a single task done.

I understand there's a massively unexpected surge of users, but I'd happily donate to help improve infrastructure (if donations were ever available)

I tried this back in April:

I liked the Matasano Crypto Challenges, but this was less informative. It's a list of tasks, not a tutorial. There weren't pointers to resources, either.

There were 20 tasks then, btw.
