Sorry for the slow response times on the challenge submissions everyone. We only have so many Mac Minis running these things . We are looking into ways to speed it up

Looks like those Mac Minis are getting smoked right now, poor little guys. I can't load the page unfortunately to see myself, but could you use GNUStep to compile the examples on any flavour of box?

I clicked "Start Course" and was greeted with a 404 that took way too long to load on my 50 megabit connection. /shrug Oh well, I'm sure there are other sites out there.

It's running on Mac Minis dude, and they're getting hammered. Bookmark it and visit again later. That's what I'm doing. :)

I know I feel so bad for them. We are working on some temporary fixes (including caching which as we all know is really easy to do) and changing the way we isolate the code submissions so we can get more throughput. GNUStep might be an interesting long term fix.

the site is very slow loading next page after clicking submit... Also, no option to skip the stupidly easy levels.

I'm actually working on extracting all the content for just a plain HTML version so people who don't want to do all the challenges will have something to read (it's almost a books length of content)

Very nice presentation, but it seems like this could benefit from an Emscriptened browser-based Objective-C compiler. Fabrice Bellard's browser-based Linux boots in less time than this prints out "Hello, world!"

We're reusing the stuff we built for the Try iOS course we came out with late last year. I've looked into Emscripten for this and from what I saw it really wouldn't work with this course, although maybe I missed something?

Looks like work has started on using emscripten with Objective-C code:

https://github.com/kripken/emscripten/pull/1162/files

Still, a long way to go.

Have you considered ccache?

http://ccache.samba.org/

You could also roll your own in a very few lines of code. Maybe even have the output of the program, not the compiled code, be the content of the hashed file, assuming you aren't reading STDIN or anything like that from the user.
