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 a topic or found an issue/bug, please could you open an issue. Thanks!
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

- 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
