Music Metadata Editor

Python Music Metadata

I got really tired of subscription music apps. They're expensive, they keep changing their libraries, and I never really felt like the music was mine. So I decided to build something simple to create my own music playlist by downloading tracks and playing them offline. But it's more than just downloading. I wanted to make my music collection truly personal. This app helps me edit metadata like song titles, artists, and album names. More importantly, I can replace the default album covers with photos that remind me of special moments, like when I first heard a song or where I was when it became meaningful to me. It's a small thing, but it makes my music library feel uniquely mine.

Spring 2020 • Reading Notes

Effective Python

Book Python Elegant

This repository contains notes that I took while reading this book. In general, this is a very fruitful journey. The author covers eight major areas about python programming, which are super interesting and especially helpful for my daily work as a machine learning engineer. For these intermediate/senior level technical books, I find that the best way to absorb them is to code as I read them through. Therefore, all the codes in this repo are the examples that the author mentions in his book. Also, since a number of chapters require some additional background knowledge, I also write them down together with my own interpretation in separate files, which live in the relevant folders. Anyway, I will be very glad if you find these examples are helpful for your projects, or you just have some fun reading them. Please feel free to send me an email if you find a mistake or you don't agree with my interpretations.

Python

As a machine learning developer/researcher, I encountered many python related questions from time to time. The majority of them are straightforward, but some are subtle to understand, and hard to be applied properly in real practise. During the process for searching answers, I realized that it usually becomes super clear if I write them down with my own examples and understanding. This repository serves as my notes to track of these questions. I usually start from the problem statement raised from a real world example, and goes to the reasons behind it. I would be also very happy if this can help you.
