From the music players of the mid-2000s to runs with my headphones on whenever I get stuck on a difficult problem, music has repeatedly changed how I experience life. This article is a personal journey through music, skill, creativity, and the pauses that restore my confidence and bring me back to programming, writing, and everyday work in my own way.

For the past few days, I have been adding features to my website. As I mentioned when I tore it all down and rebuilt it last time, I used AI to recreate most of what the old version had, moving its features and interface to a rewritten version built with a new stack. Up to 99% of the code was not written by me at all, but by AI. Still, I had to understand the core because I was the one guiding AI in that direction; I did not want to let it decide everything on its own because that could easily get out of control. Article data is stored in an SQLite file, then 11ty extracts it to generate completely static HTML pages. A script...

Hello readers of 2coffee.dev, four months have flown by like the wind, and this time I'm back with a new article. How have you been? How are you adapting in this era of AI dominance where almost everything in work is being automated? Every now and then, a few friends ask if I'm still writing. Do I use AI to write? Hmm... definitely not. Why would I use AI to write when anyone can use it to churn out countless articles to their liking? I mean, if they want, they can use AI to generate articles and read them. But if you ever feel the need for something fresh, come back here β because all the content here is crafted by me, with many hours of reflection.

Since I was a child, I have known about the arcade game machine with a green or red joystick that looks very much like a chicken leg, on the left are 5-6 brightly lit buttons. Living in a relatively bustling place, I rarely saw a shop like this. I still remember that sometimes when I came back from school, it felt like some invisible force pulled me inside to watch what people were playing. If I managed to save 1-2 thousand for breakfast, there was no way I would remain a spectator. It's been too long to remember every detail, but the allure of video games is real. 2008 was the first year...

The self-learning article series on Rust has now reached the Iterators article, almost covering the basic knowledge of Rust, after which comes advanced knowledge such as smart pointers, async/await, channels, and much more. But I must honestly say to the readers that in the end, the knowledge retained in my head is quite minimal. If you have been following the article series about the self-learning process of Rust, most of what you see is theory recorded according to the original article at...

Hello, have you ever struggled with Google to find a place that allows free usage of large language model APIs (LLMs)? I have been like you, trying to search all over the Internet only to realize that... there is no such place. But at least I found some providers that allow trial API usage, or in other words, you can use them but with certain daily limits. Clearly, the reality is that...

Hello readers of 2coffee.dev, it's been a long time since I last sat down to chat and inquire about everyone's health. Today, the weather is a bit chilly, feeling as if winter is very close, just waiting for that invisible door to swing open and let the winter winds rush in. A few days ago, probably due to the sudden change in weather, one side of my nose got completely blocked, making it hard to breathe, yet all it took was diligently drinking fresh ginger with warm water every morning and evening, and after just three days everything returned to normal.

June is a special month, even more meaningful as it marks one year since I released the OpenNotas note-taking application. At that time, it garnered significant attention by ranking in the top 2 products with the most votes of the day on ProductHunt - a playground for product enthusiasts. The feeling was indescribable as it was the first time a Vietnamese product was well received on an international stage. I owe a lot of thanks to those who followed and responded to my call on social media where I posted the article. Currently, OpenNotas has attracted over...

I remember back when I first started my career, one thing that haunted me was dynamic design. It meant from one feature, this input, that output, but before doing it, I had to think hard about whether I could cover all future scenarios. The easiest example is creating dynamic input forms in a content management system - CMS. A dynamic input form means...
