Movie Review: Kiki's Delivery Service

Kiki’s Delivery Service (or Majo no Takkyubin, in Japanese) is a Studio Ghibli animated movie, written, produced, and directed by Hayao Miyazaki. This movie was released in 1989 - before I was born. But, like the other Studio Ghibli movies I’ve seen, it still seems so ahead of its times.

This movie is about Kiki, a 13 year old witch, who, according to tradition, has to move away from her family in order to train herself and become independent. But even as a nearly 30 year old woman, I can relate to it.

Kiki arrives in a new town with her black cat, Jiji, and sets up a delivery service. Through her adventures in this new city, the movie shows Kiki meeting wonderfully kind women, pulling and pushing each other up. I haven’t come across many movies with such splendid female characters. (And this was in 1989, folks!)

Suppose I want to generate random numbers that are drawn from a discrete power-law distribution. This is how I'll do it.
Again, if the github link doesn't work, click here.
Note that I need to finish notes for this notebook...

Code snippet to calculate degree distribution of given network. My earlier code barfed out all the degrees for which counts were zero, along with the others. This one doesn't.

In the midst of covid19, I decided to learn some network epidemiology.
So, to start this off, check links here, here, and here for some playing around with the SIR model.
And, the following is an eye-catching plot you see in the news these days:

I think I can speed things up more. But need to figure out how, and understand how numba works.

This is my previous post on education.
I saw this YouTube video and wanted to share it somewhere.

Given a weighted network, I want to extract a list of edges with weight wi, wj, etc.
There may be a shorter code to do this. If I find one/figure it out, I'll put it up.
Look here for the jupyter notebook.

Education

These musings should be revisited and revised, regularly.

2019-Dec-26, Thursday
How important are schools/colleges/universities/institutes of higher learning in imparting education?
But first, what is an education? What is learning?
Is it possible to practically disentangle teachers from institutions of education (examples above)?

100 Days of Github. Take 2. Update.

You might have noticed that I did not put  the "day left" etc metrics at the end of my last post. It's because I am exhausted. This 100 days of github challenge has been tough. And it is clear I will not be able to finish it. 54 posts in 10 days? No, not happening. As usual, I bit off more than I could chew.

I forgot that my work and just plain ol' life might get in the way of github-ing. Also, my incessant need to "if not perfect, then nothing" attitude didn't help, although I admit this exercise helped me get out of this toxic mentality.

So, finally: I will not be able to finish 100 github posts in 2019, but I am not going to stop this 100 days of github challenge. I will just be a little easy on myself, and not have this constant nagging in my head. Look out of spillovers in 2020. And hopefully, I'll just continue github-ing something or the other after that.

See you in a bit.

Animating a billiards ball rolling around on a billiards table.
Github link here and nbviewer link here. (Nbviewer link preferred.)



This one took a while for my brain to figure out, because I wasn't thinking clearly about the ODEs. A very "d-oh" moment.

A point to note is that along with MyEps, the time step of the ODE solver plays an important role in determining how fuzzy the wall will be.

Another point to note is that the ODE solver I have used here is the very modest Euler method, because the ODE RHS function is linear in the variables, and so I don't need a higher order solver.
