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

Creating awesome text banners in Linux Terminal

-
In several opensource projects that we see around in the web, certain developers prefer to add banners like the following at the top of the source code. These do look cool, but I have often wondered why anyone would waste so much time making things like these.

As I have been surfing around the web, I happened to see Linux Terminal apps that generates these for you. I have used them to generate such banners for the BuddyGo.

Figlet:

To install Figlet, use the following command (if you have apt-get):
sudo apt-get install figlet

Toilet

To install Toilet, type the following in your linux command line:
sudo apt-get install toilet

Banner:

To install Banner, type the following in your linux command line:

sudo apt-get install sysvbanner


Now, you can also contribute to the Open Source community in style. Make contributions on GitHub, BitBucket, or whichever platform you are using.

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
