The malloc stuff is tough. So much to read!
The Skiena book exercises are pesky. So much to solve!
I'm stuck on a couple of Euler Project problems. I could pick another one (and I do) but... yeah.
My compiler doesn't love me any more. :(
Apart from all that, I need to pack up an entire house for (finally) moving country. I will never shop for anything again, I swear, I'm cured!
