Today I learned that while AI is great, sometimes it’s faster to just hit Ctrl+G in VSCode and tweak the CSS yourself than to ask a model to do it.

This chart is a great resource for understanding time and space complexity for different array sorting algorithms. I was trying to create my own version to study, but this one is so much clearer and more comprehensive. #Algorithms #Coding #Programming #ComputerScience #Tech

Spent the last two weeks chasing down a single bug 🐛 20 iterations later, it finally works. Longest debug session of my life (so far)—so relieved it’s over! 🎉

Been wrestling for a week just to get my React Native app running on iOS. “Learn once, write anywhere” feels more like “struggle everywhere, hope it runs.”

It's very cool when you see that something you made helped someone else

Using AI for unit testing has been a game changer. It took some time to set up, but now the LLM has a deep understanding of how the app works — and plenty of guardrails to keep it from going off the rails. Highly recommend it! #AI #UnitTesting #LLM #DevTools #CodingTips
