Advent of Code 2024

I have decided to challenge my problem solving by following through on Advent of Code this year. “Advent of Code is an Advent calendar of small programming puzzles for a variety of skill levels that can be solved in any programming language you like. People use them as interview prep, company training, university coursework, practice problems, a speed contest, or to challenge each other.” I’m solving the problems in Java since I use it at work and feel most comfortable with it.

How to fix messed up internal VPN on Ubuntu

For legal and sanity reasons, there’s no classified stuff here. To anyone from work: Yes, I fixed it. Crisis averted, lesson learnt. This is mostly a note to self in case I try to fix this issue when it happens again, and I need to revert everything. Problem WiFi works 10/10 on work laptop. VPN works 5/10. It connects, works for a few minutes and then it just stops working. Even after disconnecting from VPN, WiFi does not work normally and a system reboot is needed.

A/B Testing 101

Since this year started, I have been working on a project on controlled online experimentation system implemented from scratch, christened: Abacus: The A/B Testing Project™. It’s currently in the SIT environment right now where I’m interning, with a few natural holdups that happen due to cross-team collaboration. Nevertheless, I’m confident we’ll take it to production soon. Case Study Let’s say I bake two different batches of cookies. The first batch I call Hide n’ Sleep (my favourite), and the second I call Padhle-G (the classic).

DAO Design Pattern with Spring Boot

It has been a couple of months to me developing a backend driven service for the organization where I’m interning. From hating the J of Java (irrationally) to easily writing complex controller classes and services with Spring Boot, this project has given me my first hands-on experience with Java, Spring Boot, and the DAO design pattern. Spring Boot Spring Boot is a framework based on Java which is used to build web apps and microservices.

srcdit

There was a phase when I was editing my .bashrc and .zshrc a lot. Having to edit them and then source them again and again soon became torturous. It would have been so much better if I had a tool to edit and source the files in just one step. The best part about being someone who works with and understands software is that I can build a tool to meet this requirement myself.
