Things that I'm learning now:

1. A new CAD software for my internship (SolidWorks is still better if you ask me)
2. A new experimental method called Design of Experiments (which my mentor learn as a module during his Masters)
3. HTML programming for my FYP
4. PHP prgramming for my FYP

I learn 1 and 2 at work, while I go back home after work to read up on 3 and 4. It's like taking 4 NUS modules, just that there's no exams. I must say that it's cool learning new stuff, I have always enjoyed learning new things, but still, not sure how long my brain can hold before it's fried.
