I teach my sons (currently they are aged 10 and 11) programming. I upload the video and write the blog.
If you would like to suggest the topics, please could you open an issue.
The videos and blog are in English. The Teaching Programming Language is Python.

I am currently a Senior Software Engineer at Microsoft Research Cambridge. Prior to that I worked as a SDE (Software Development Engineer aka Someone Does Everything) for Amazon Web Service (S3 Object Lambda) and as a Staff Software Engineer for General Electric Smallworld when I added while loop, regex, http library and so much more to the Magik Programming Language.
My profile at Microsoft Research Cambridge - and you can view my latest updates at my person website: https://zhihua-lai.com
- Youtube Channel: https://www.youtube.com/c/DoctorLai
- Blog: https://helloacm.com/category/teaching-kids-programming/
- B 站: https://space.bilibili.com/1826201500
- 西瓜视频: https://www.ixigua.com/home/1399016302059111
Most of the videos are based on a Leetcode and/or BinarySearch problem, which you could find the Problem ID on the video whiteboard left corner, or alternatively, you can find it at the list i.e. the "Resource Links" column
I used to submit solutions to binarysearch.com however it seems the website is down forever.
You can improve this! Thanks. see here
