Err, you can still run interpreted programs on a filesystem mounted noexec:

~$ python myprogram.py

A sufficiently clever user could use an interpreter to write his own dynamic linker and thereby run binaries too.

No he cannot, as he cannot write that interpreter to a place where it can be executed.

Besides, such an interpreter already exists on your system and is called /lib/ld.so or one of its newer names. Note that trying to do this trick doesn't work, as your linker then needs to mmap this code with PROT_EXEC which is not allowed for files residing in a noexec mounted fs.

Journal Journal: Using Google Adsense for Charity

Journal by Raindeer
I hope Slashdot-readers will help me generate more attention for this idea and come up with ideas to get this idea higher up Google's to-do-list. I have blogged about this on my blog. The origins of this idea lie in me looking at the enormous amount of $8 on my Adsense account (the payout limit is $100) and wondering if there was something better to do with it, instead of waiting 12 years for the first check.
