Dear Vishi, this is my daily log for July 10, 2022.

## Kickboxing class

I was supposed to go to a kickboxing class today. I have previously enjoyed these classes which are a mix of cardio and kickboxing. It helps me vent out any stress I have. If you remember in my childhood I had developed an uncanny habit of punching the brickwall barehand. I guess it much better punching the bag wearing the gloves to avoid unwanted injury.

It so happen that Chitragupta had different plans for me. However before departing, I found to my horror that my house keys were missing. I frantically searched whole apartment but all in vain. I hoped that reading of Sherlock Holmes 🕵️ would aid me with in my pursuit. I reorganized my clothes, threw unwanted thrash, painstakingly searched every needle in the apartment, vacuumed the carpet yet it was a utter disappointment. The current of time never stops and I missed my class. Crestfallen I crept back to my bed to sleep again. However luck has its last revenge. The only place I didn't search was my bedsheet. For all its worth, at least I spent some time cleaning my room.

## 2d nested list in Python

In python programming language, there's an interesting concept about nested list

Lets say if you define a 2d list like

``````matrix = [[0] * 3 ] * 3

print(matrix)
[[0, 0, 0], [0, 0, 0], [0, 0, 0]]
``````

If you want to only update value at location at [0, 2]

``````matrix[0][2] = 5

print(matrix)
[[0, 0, 5], [0, 0, 5], [0, 0, 5]]

``````

This is incorrect as it updates value in all the remaining list. So the correct way to define 2d nested list in python is

``````matrix = [[0] * 3 for _ in range(3)]

print(matrix)
[[0, 0, 0], [0, 0, 0], [0, 0, 0]]
``````

Now if you update value at location at [0, 2]

``````matrix[0][2] = 5

print(matrix)
[[0, 0, 5], [0, 0, 0], [0, 0, 0]]
``````

## Reading The Origin of Species by Charles Darwin

There's an interesting tidbit about pigeons in India during Mughal period. "Pigeons were much valued by Akber Khan in India, about the year 1600; never less than 20,000 pigeons were taken with the court (sic)", Charles Darwin on Akbar.

Interestingly Odisha Police still has a pigeon service to communicate in remote areas with no wireless or telephone links. The messages, written on a piece of paper, are rolled and inserted into tiny plastic capsules and tied to the feet of the pigeons1.

## Eating at Taco bell

I usually dont like Taco bell. However lately I become fan of Fiesta Veggie Burrito. You can add Jalapeño Peppers to the order which make it more crunchy. I guess I would be eating it often until my taste buds revolt.
