One of the first things I learned this year is that it's very important to conduct retrospections frequently. In fact, I think the leading cause of poor/unsatisfactory life decisions is the lack of reviews. Because I'm still a student, a

First, I'd like to make it clear that I hate overly positive posts such as those on LinkedIn. They sound fake as hell - I bet at least half of them are. Everyone sounds like they are forcing a smile to look good to their future employer.

I guess thunders do strike. I passed most of my childhood without a thought of pursuing computer science. In fact, most of it went by without much thinking at all. I just entertained myself by doing whatever I enjoyed regardless of whethe

Alternate title: JS dev shocked to learn Rust is indeed a low-level language Rust is the 5th language I'm learning seriously. First was Python, then C#, JavaScript/TypeScript, and C. I've dabbled with Java, and wrote a bit of Lua, but not

Web development was the highlight of 2021. I'm now actively learning full-stack web dev, and fairly confident with the front-end. Out of all things, the most important thing I learned was that this is something I'd really enjoy pursuing a
