https://adventofcode.com/2025/day/8 Given a list of junction boxes' coordinates we have to find the closest junction box pairs then we have to figure out the circuit lengths. I tried with the naive set based approach initially but that didn't work out for the actual input but worked for sample. Then I learned about this new concept (for me) - union find algorithm - from graph theory. Using that…
Today I have solved and understood advent of code 2025, day 7. Learned a lot about DP. Gemini helped me through the concepts. I have initially solved with my approach but that was running forever then learned about this DP concept. Watched a YT video by hyper neutrino on the solution as well and found out a similar solution with a different type of DP. Enjoyed learning these concepts and reading…
https://adventofcode.com/2025/day/7 How I solved? I'm trying to follow the beej's guide approach. Understand. Plan. Code. Reflect. What is my understanding of this problem? A particle flows down - when it hits the splitter - it gets split in 2 paths. For part 1, they have asked how many times the particle splits. What I did? I have went through each row - if I see a . - i just replace it with | if…

I always wanted to understand the meaning of the songs. (I am a non-native english speaker - so I can't understand easily). So I built this - https://maheshkumar.blog/songs/ with the songs I like - so that I can understand them better. Like a wiki page but for each song. Maybe in future I could extend each page with my own understanding of the song. Let's see how it goes. Another day, another…
Finally watched it Today. Longtime watch list movie. Finally. Great movie. Loved how andy and red moved along in their path. Brooks ending was sad. Loved how he took care of Jake (Bird). Beautiful movie overall. How andy navigated 19 years of prison life with his knowledge and his skills, it's just awesome. I initially thought he did the murder. I didn't believe until the truth revealed. Poor…

Previously I had applications lived through subdomains like f1.maheshkumar.blog , football.maheshkumar.blog - soon it became tedious maintain. Today I got the chance to revamp them all. Instead of having them all in separate domains I put them under maheshkumar.blog sections. F1 & Football - refreshes in the background and show the read only data to user - so why having it as a python web app?…
It is 11:00 PM as of I am writing this. I stepped outside for a break. Then I saw the vast black sky covered with twinkling stars and a planet (Jupiter). I saw the constellations Orion and The Big Dipper (Ursa Major I guess?) Nostalgic. Takes me back to the COVID Lock down days. During those days I started exploring astronomy. I was there. Sitting or standing - staring at the sky. Its just giving…
