Free Workstation? 🙋‍♂️ Count me in! I picked the free gaming workstation. Surprise twist—the HDMI output gave me no signal. Of course. The machine was a box of mysteries, but with an NVIDIA sticker on it, so I had a good hunch about the GPU.

I wasn't trying to build …

Visualizing Covid-19 cases in San Diego by zip code using Bokeh

I was refreshing my understanding of probability and random chance. I think that a simple experiment of tossing a coin and observing the result is very useful in understanding these concepts.

As we know a coin when tossed/flipped will result either in a HEAD or TAIL. So a simple …

I have been using VIM lately for software development in Python. I gave a lightening talk on my experiences using VIM at San Diego monthly meetup.

As I was migrating blog posts from my wordpress website to pelican based static website, I noticed an old python code written for communicating and controlling a Princeton Instruments Acton SP2150i Monochromator.

As I looked at the code, I noticed methods in the class such as get_nm() and set_nm(). I …

It is common to measure the peak absorbance of the plasmonic nanoparticles in solution and then get the following:

1. Molarity (moles/liter)
2. Number of particles per ml
3. Weight concentration (ug/ml)

I wrote a small python function to extract these parameters.  The following inputs are needed for the function

1. d_nm …

Energy band diagrams are used to visulize the electron and hole transport in Solar cells and LED research. I want to quickly draw them and came up with a python module.

My wife and I have a good meal and leave the house. After 20 minutes or so, we are in the car and I ask my wife, did we turn off the stove?

My wife answers…you were the last one to cook. What to do now? Go back home …

Coupled dipole approximation (CDA) method is a numerical method to calculate the optical properties (scattering and absorption) of interacting dipoles. This method is used in discrete dipole approximation method (like in DDSCAT software), where a big particle (also known as target) is broken into lot of interacting dipoles arranged in …
