Introduction Coding with children is a topic close to my heart.

Last update This post was last updated on August 29th, 2024.

After a longer break I continued working on my machine learning basics repository which implements fundamental machine learning algorithms in plain Python.

I posted another notebook in my machine learning basics repository.

Books I am currently reading Mindset by Carol Dweck (Link to book) Books I have read Atomic Habits by James Clear (Link to book) A Promised Land by Barack Obama (Link to book) The Alchemy of Air by Thomas Hager (Link to book) Superintelligence: Paths, Dan…

I finally found time to continue working on my machine learning basics repository which implements fundamental machine learning algorithms in plain Python.

I recently finished reading the book Deep Work by Cal Newport.

My magical universe: “The Tales of Castle Kilmere” The main character of our magical universe is named Lissy Spinster.

I have decided to take on a new habit using a technique I found on the ‘get discplined’ subreddit.
