Idli from The Rameshwaram Cafe, Bengaluru OK, 2026 is here now! Keeping the tradition alive, here is another yearly review blog. Ever since I started writing these, it has never been this difficult to write, thanks to AI, I can barely write anything anymore, but I’ll try to write whatever I can for 2025. Work Consulting (Quansight / OpenTeams) I spent the better part of 2025 doing what…
A beautiful house somewhere in Norway OK, I have finally got the time to write this one, just like the year 2022 review, this one is also about an year late. This is the 8th consecutive year I am following the tradition of writing the yearly review blog and one thing that has been constant throughout these years is my ability to procrastinate on this. The more I procrastinate about it, the more…
Your browser does not support the video tag. A walk along the river Thames on my 2 hour journey to the Riverside Arts center for theatre rehearsals. After writing the year 2022’s review blog post in December 2023, my only expectation for the rest of 2023 has been to pen this one before the onset of 2024 as I had a hard time recalling the events of the previous year. Let’s try to recall…
An ordinary soda during sunset in Maldives Year 2022 was quite an year for me. Apart from travelling around the world twice, this year was quite happening for me, witnessing various developments in professional as well as personal life. Work I worked for Quansight for most of the year, except for 3 months break I took in summer. I worked on various Open Source and client projects this year. Some…
It’s been 5 years, since I last spoke at PyData London. Similar to what happened 5 years ago, this time also, we had a speaker cancellation, so I jumped in as the last minute speaker, although I had proposed to speak next month. The meetup started with Emlyn , welcoming folks to the meetup and introducing them to PyData London. He also shared updates around the Python community, like the…
So, finally the time has come to write this one. I was quite proud of myself, when I managed to write the previous year review blog (2020) , 5 days before the year ended. Unfortunately, this time I am only 10 months late. I can blame 100 things, but the truth is I have been lazy. Okay, enough of guilt trip, lets get on with the review. So, at the start of the year 2021, I moved to Manchester for 6…
If anything kills over 10 million people in the next decades, its most likely to be a highly infectious virus rather than a war. – Bill Gates (about 5 years before COVID-19) Life in 2020 wouldn’t have been this miserable, if we had payed attention to this guy five years ago: This comment really nailed it! At the start of 2020 I returned from Thailand after having a great time with…
This summer I had plenty of time during COVID-19 lockdown and I was looking at SymPy Gamma . Sympy Gamma SymPy Gamma is a web application that executes mathematical expressions via natural language input from the user, after parsing them as SymPy expressions it displays the result with additional related computations. It is inspired from the idea of WolframAlpha which is based on the commercial…

This is an anecdote of my Journey to the United Kingdom for PyCon UK . It was held at Cardiff, the capital of Wales (a country in South West Britain). I took a flight to London from Delhi via Doha (Qatar) as it was cheaper than directly getting to Cardiff. I usually prefer flights with layovers, when I am not running short of time as it gives me an opportunity to have a glimpse of culture of…
I was done with my college exams by the end of May 2016, and was looking to work on something interesting. I had an internship offer from HackerEarth in Bangalore, which I had applied for couple of months ago. It was a tough choice as I had to decline a full time offer for this internship. I chosed to intern at HackerEarth as I had heard good things about HackerEarth’s Engineering Team. I…
“Respect Diversity” is what comes to my mind, when I recall the PyCon Asia Pacific 2016 in Seoul, South Korea. It was probably the best conference I have ever been to in the recent times. I made a lot of friends and meet some amazing people there. Thanks to the PyCon SG and PyCon APAC for helping me financially in attending the conference and giving me the opportunity to present there.…

Hi there! It’s been 11 weeks into GSoC and we have reached into the last week before the soft deadline. Here is the Progress so far. Progress of Week 10 & 11 Last couple of weeks, I worked mainly on the Documentation of the solveset module. It’s very important to let others know what we are doing and why we are doing, so this PR #9500 is an effort to accomplish that. Here are some of…
Hi there! It’s been nine weeks into GSoC . Here is the Progress for this week. Progress of Week 9 This week I worked on Replacing solve with solveset or linsolve in the codebase: Here are the modules, I covered, as of now: diffgeom calculus core functions galgebra geometry ntheory simplify series sets stats @moorepants pointed out that I should not change old solve tests, since people may…
Hi there! It’s been eight weeks into GSoC . Here is the Progress for this week.

Hi there! It’s been seven weeks into GSoC and second half has started now. Here is the Progress so far. Progress of Week 7 This week I Opened #9628 , which is basically an attempt to make solveset more robust, as I mentioned in my last post . The idea is to tell the user about the domain of solution returned. Now, It makes sure that n is positive, in the following example:
Hi there! It’s been six weeks into GSoC , and it marks the half of GSoC. The Mid term evaluations have been done now, Google has been preety quick doing this, I recieved the passing mail within 15 minutes after the deadline to fill up evaluations, so basically GSoC Admin did the following, (I guess): SELECT * FROM GSoCStudents WHERE EvaluationResult = 'PASS' ; and SendThemMail (Don’t…

Python has a pretty good support for Higher order functions, we are going to learn their implementation here :bulb: . What are higher order functions? “Functions that take a function as an argument or return a function.” Example: def foo ( f ): f () # calling the function that is passed def bar (): print 'Hello bar' foo ( bar ) # function bar is passed to function foo. Hello bar…
I have been procrastinating for this for a long time, but finally I made this transition from Wordress to Jekyll yesterday, though it doesn’t requires you to be a ninja but you need to patiently learn the things for once atleast. I skimed through several blogs to learn the process, but I found this pretty usefull: http://jmcglone.com/guides/github-pages/ Good Links Markdown Cheatsheet Github…
Problem: In this Problem , we are required to find Factorials of numbers ranging from 1 to 100, but Since an unsigned 64-bit Integer can store upto 19 decimal digits, where as 100! has 150+ digits, so we can’t use Int Data type. The simplest data structure which can be used to store such results is an Array. In the simplest form we can store 1-digit at every index of array.
