Simon creates a playlist with Sorting Algorithms tutorials in Python

Simon’s chart of sorting algorithms ranked by efficiency

Simon has started a huge new project: a series of video tutorials about sorting algorithms. In the videos, he codes on his RaspberryPi, but here is the link to the Python code available on his GitHub page (that he continuously updates):

Today, Simon has recorded the fifth part of the series, in which he explains and applies the Quicksort algorithm. [The coding part goes very smoothly and much quicker (hehe) than in the previous sorting videos we have made so far. Simon also came up with his own code, he didn’t look the code up].

And here come the previous parts of Simon’s sorting algorithms series, also available via this link to a playlist on his YouTube channel (there will be more videos coming):

the bubble sort video
the selection sort video
the insertion sort video (took Simon two days to make)
the merge sort video (was the most painful one)

Simon is also fascinated by more exotic sorting algorithms, such as a sorting network:

Simon used the following resources: Daniel Shiffman’s tutorial on Quicksort, Timo Bingmann’s sort algorithms visualization, Must Know Sorting Algorithms in Python, a medium blog on sorting algorithms,’s computer science courses, Wikipedia.

Building a 2048 Game. Part 3.

Simon’s general plan for his 2048 project:

Link to the project in progress on GitHub:

In this third part he shows how he changed the fonts, how that messed up the code, how he solved that problem and also how he created a function to move any tile anywhere else on the grid. Simon doesn’t yet have the function to move a tile to the right place – he’ll cover that in game mechanics in Part 4.

Simon’s own 2048

Link to the project in progress on GitHub:

Simon has started building his own 2048 game. In the two videos below he explains the initial stages of the project and how he has created the tiles. At the moment, he plans to build a classic 2048 first and create a few desktop versions of more exotic variations of 2048 later.

Simon speaking at the Processing Community Day in Amsterdam

Simon had his first public performance in front of a large audience last Saturday (February 9, 2019): he spoke about his Times Tables Visualization project at the Processing Community Day in Amsterdam!

Simon writes: You can access the code of the poster and the animation (and the logo for my upcoming company!) and download the presentation in PowerPoint, on GitHub at

If you’d like to buy a printed copy of the poster, please contact me and I’ll send you one. Status: 3 LEFT.

There was a lot of interest in Simon’s project
