From Correlation to Causation through stories and math

-

Correlation and causation are two concepts that people often mixup in their minds. I must admit that I myself have been guilty about this, and it unlikely that I would ever entirely grow out of it as it is wired deeply into our psychology. Let me use this article to briefly emphasise what the concepts of correlation and causation means, some interesting stories that have emerged from people misunderstanding these concepts and an algorithm that attempts to find causal relationship using correlation information. Here is a story that I heard a professor of mine, Prof. Dr. Ernst-Jan Camiel Wit, tell us during a lecture. There was a school that was involved in a study to see if providing free mid-day meals to students, which they could choose to be subscribed to this or not. At the end of the study, both the students who subscribed to it and did not where tested for different health indicators. It was observed that the students who chose to have meals from the programme had poorer health

Went into the University for the first time

-

I went into the university for the first time today. It is less than a kilometer from the apartment. I had to go there to finalize certain documents regarding my accomodation.

I arrived at the university during the lunch time and hence I had to wait for a couple of hours for the office staffs to return. During the time, I roamed around the campus. The place is aesthetically pleasing, however, it is pretty small, especially since where I did my bachelor's, IIT Patna, had a campus spread across over 500 acres.

I also went to the nearby Lidl to get a few frozen pizzas. I had that for lunch, evening snack and dinner. I had thought about cooking something for dinner, but I felt a bit lazy to do the same. However, I did modify the last frozen pizza by adding some mushrooms, pizza sauce and pepper. I think this could be a good trick moving forward - buy a few frozen pizzas and chopped vegetables from Lidl and fuse them. I think this would make the pizzas a bit more healthier and the effort that I have to put in would be minimal.

Started a blog under HexHoot

I think it is for the best to start a separate blog under HexHoot. This will help me promote the project by making lots of content related to it, which could eventually drive traffic into the page. I really am betting on HexHoot taking off. I see a lot of potential in the project. Check it out:  https://blog.hexhoot.com/

Bought a new domain - chickfort.com

-
A couple of days ago, I bought a domain named 'chickfort.com'. I have been wanting to own a '.com' domain for quite a while now, and I didn't want to buy one from a reseller. Every now and then, I used to go to one of the domain registrants and search for interesting names that would come into my mind. This has been going on for quite a while, and I finally found a domain name that is short enough and is a combination of two simple English words. The aforementioned is not the main reason why I chose to buy this domain. The words 'chick' and 'fort' coupled together could be loosely translated into the endonym of my hometown, Kozhikode. Additionally, I believe that the domain name could be potentially used for a wide-variety of purposes. The interesting thing is that, I have been receive calls from a few software and web development companies after I made this purchase. I wonder if the domain registrar is secretly sending the data to the marketing team

First impression of Lugano - Mindblowing

I started off from Zurich at around 7.30 in the morning. There was a direct train to Lugano from Zurich HB. I vaguely remember my internet searches on the cost to travel from Zurich to Lugano via train to be about 30 CHF, but in reality, taking the ticket from the station, it costed me double of that. I don't know if the tickets have surge prices or something. Anyway, the journey was nice as I was able to see some beautiful places along the way and I think I had a chance to go through Gotthard Base Tunnel, which is the longest tunnel in the world. Getting down at Lugano station and looking out, I saw one of the most beatiful scene that I have ever seen. I am not sure if I could describe that properly in words, nor do I think the following photograph that I took justifies how it looked to me in person. I had to walk down a lot of stairs from here with the heavy bags that I had, only to realize that I made a wrong turn at some point. I was informed that instead of going back up, it w
