Curve fitting: A presentation
I delivered a talk on curve fitting today in the physics department
seminar room. This is the presentation I used. The objective of the
talk was to familiarize everyone with the chi-square distribution and
chi-square fitting without focusing too much on the implementation
details. Since the complete audience didn't have background knowledge
of probability theory, I had to briefly touch up some concepts like
Cumulative Distribution Function and Probability Density Function.
Overall, I think the talk came out alright, although it was apparent
that some of my fundamentals were holed. It's a miracle it even came
out, considering that I was delivering it on a paracetamol-suppressed
headache and fever.
Finally, LaTeX + Beamer is too awesome!

Cellophane sheet method of visualizing pointers
While going through some unused parts of my hard disk, I found
something pretty fascinating. I wrote this out in 2007 to explain
pointers in C to someone. Hopefully, someone somewhere will find it
useful :)
