log 4 = 0.6020


hurray! I went out every morning and jogged/walked in the park.

I spent lot of time on relaxation last week. This week, I am positive that I could be more productive and I am planning to achieve one of the hardest goal for me “Do physical exercise everyday”

Lets start.

Time and Task management

I have been experimenting a lot on managing time and getting stuff done. I want to take control of it. So badly.

One of the craziest things I did this year is, I managed my time and task by using a bug tracking board on Source Control Management platform called Gitlab. I got this idea from work. I was able to do it for a month. But, eventually got bored, as I do the same thing at work for managing tasks.

So, I moved to Trello few months back. It’s actually good and I am using it in very minimal manner ( I open it once a day, to note down important backlogs ). However, I am still experimenting with it ( for months ).

This week, I am going to use a new setup of my Trello board and important principle to take control of my time back. The important principle is “Knowing what is right and doing it”


I started to explore various kinds of trees and how they could be useful. Till now, I have come across the below tree types

  • Binary tree

  • Binary search tree

  • 2–3 tree

  • 2–3–4 tree or 2–4 tree

  • AA tree

  • Red Black tree

  • Threaded Binary tree

Even though I did not spend more time in learning them in detail. I just grasped the basic ideas behind them.

Tagged union and trees

I came across tagged unions long back. Interestingly, I just realised that it could be used to implement some complex tree structures in a very simple way. For example:

Child of a node could be expressed as a tagged union of nil or node containing two children or node containing three children

@left : Nil | TwoNode(T) | ThreeNode(T)

Power in my hands

Query Plan Analysis

I saw this interesting tweet and boom! I happen to discover an interesting query in Postgres, that helps us to analyse other queries.

There is this query called EXPLAIN in postgres, which will helps in analysing the SQL query we write.

Example query from [https://www.postgresql.org/docs/9.1/static/sql-explain.html](https://www.postgresql.org/docs/9.1/static/sql-explain.html)Example query from https://www.postgresql.org/docs/9.1/static/sql-explain.html


I don’t like doing things in a rush. I originally intended to write something about doing things in a rush and its after effects. But it’s a subject that needs to be written not in a rush. So, will try to note down some ideas about this topic in future, if I feel like to.

But for now, avoid doing things in a rush with an obscure plan.

Suicide Linux

I tried out this fun project in a docker container. It’s fun and give it a try.

Blog post on Trees

I am writing a blog post on some interesting things i happen to discover about the tree data structure and I have named this blog post as “Trees are green”. By far, it’s going pretty good. I hope to get it out soon.


Back in the November of last year, I and my friends ( Venkat and Vasanth ) started working on this project called microplan. It is a very simple command line tool for planning projects via issue trackers.
microplan - Plan your project from command linegithub.com

I happen to work on it a bit, this week. I use this tool a lot at work. We are very much excited to go for a 2.0.0 release of this tool.

TODO for medium blogs

I happen to discover this super cool feature from medium this week. I always wanted the ability to have TODO markers in blog posts. It seems like it already exists in medium


  • [DONE 6/6] Go out and jog/walk early morning ( 6 days streak )

  • [DONE 5/6] Learn one new data structure everyday ( 6 days streak )


Overall this was a productive week for me. I hope to maintain the spirit over the next week too. However, I will be travelling in next week and might be a bit hard to maintain some things.

Thanks for reading. I quote verses from my favourite Tamil literature “Tirukkuṛaḷ” at the end of my blog posts.

“கேடில் விழுச்செல்வம் கல்வி யொருவற்கு

மாடல்ல மற்றை யவை.”

— திருக்குறள்

Translated meaning ( in my words ): Education is the only wealth of a man that could not be destroyed. Any other wealth is not considered to be a wealth in front of a man’s knowledge through education.
