Photography tips and advice
After seeing a couple of list of photography tips, I’d like to share some of them and a couple of my own:
- Always shoot in RAW! Really…always!
- Make sure that your RAW files are saved lossless and at the highest bit-depth (10, 12, or 14 bit typically)
- Think then shoot, not shoot then think
- Know the limitations of your camera
- Know the functions/buttons of your camera

Bifurcation diagram :: Logistic map
In this blog post I will show you some ideas on how to plot a bifurcation diagram. I will use the well-known logistic map:
x[n+1] = r*x[n]*(1-x[n])
For every r we can start with some value x(0) and calculate x(100000) by repeatedly applying the above function. Where will it end up? And how does it depend on r?

Pasta :: NYT :: Discovery Channel :: NRC :: RNW [Updated III]

As quite a few have asked; what is the process of creating a pasta, here is a video describing the process. Based on a lemniscate, we extrude it, and twist it! That’s it!
