+### 1.1 -  Reduce writing friction
 
 This new version of my website was built with the idea that I should be able to add, edit, and delete content directly from the front-end. This means that everything needs to be backed by a database or CMS, which quickly adds complexity. But at the end of the day, adding a bookmark should be a matter of pasting a URL and clicking save. Writing a blog post should be a matter of typing some Markdown and clicking publication.
 
 Extra friction on these processes would make me less likely to keep things up to date or share new things.

 I want my website to be a playground where I can safely experiment with new technologies and packages, including testing frameworks (like the new Nuxt 3 stack), improving CSS styles with Tailwind, and discovering new technologies and frameworks, in a way that allows for easy isolation and deletion. This requirement made Nuxt.js an obvious choice, thanks to its support for hybrid page rendering strategies—static, server-rendered, or client-rendered. More on this below.

 Nuxt.js is my front-end framework of choice. I particularly appreciate it for its comprehensive and complementary Vue and Nuxt ecosystem. The filesystem-based router provides an intuitive and powerful abstraction for building the route hierarchy. Nuxt.js also benefits from a large community that has thoroughly tested the framework, addressing edge cases and developing creative solutions for common Vue, data recovery, and performance issues. Whenever I encounter a problem, I turn to the Nuxt.js discussions on [GitHub](https://github.com/nuxt) or their [Discord server](https://go.nuxt.com/discord). Almost every time, I find that others have already come up with innovative solutions to similar challenges.
 
 Nuxt.js is also fast. It optimizes performance by speeding up local builds, automatically compressing static assets, and ensuring quick deployment times. The regular project updates mean my site continually gets faster over time—at no extra cost!

 Neural networks are a class of machine learning algorithms inspired by the functioning of biological neurons. They are widely used in artificial intelligence for image recognition, natural language processing, time series forecasting, and many other fields. Thanks to their ability to model complex relationships in data, they have become one of the pillars of **deep learning**.

Finally, a structured workflow and metrics like the R² score ensure the quality of predictions and analyses.
