Code Editor with Webcam

Simon has come up with a code (in Processing) for an editor that includes live Webcam image to help him record coding tutorials. The project is still in progress.

28 times 28

Simon programmed a presentation to explain why 28×28 is not the same as 20×20 + 8×8 geometrically. The code is quite complicated and involves some trigonometry and conditional statements: the grid is divided into different parts every time Simon clicks and depending on how many times he has already clicked. This is typical Simon – coming up with an inherently arduous and complex system to visualise the beauty of the world around him, even of the seemingly trivial things. By the way, the inspiration for the 28×28 grid came from Simon’s favourite math channel, 3Blue1Brown and its latest video on Neural Networks (the grid was used to explain computer vision).

Simon is doing quite a lot of sums in his head nowadays, looks like it’s a new trend. Today, while bathing in the fountain outside, he was calculating how long 1/16th of a minute lasted. And a couple days ago, while waiting for his appointment at the hospital, he calculated how long it would take someone to read a whole page of random numbers, taking an educated guess that one takes 4 seconds to read out one number and remembering Daniel Shiffman mentioned there were 100×5 numbers per page in his book.

Cannon Game in Processing

Simon shows the Cannon game he created in Processing (Java). He says he was inspired by the Stackoverflow forum, where he saw an example of the game and later wrote the code for a similar game himself. I saw him quickly write the code in a matter of perhaps two hours. Simon will post his code on GitHub once he has added a couple extra features.

Processing on RaspberryPi

Simon installed Processing on his RaspberryPi recently (using the terminal, which looked terribly sophisticated and scary as on Linux you’re forced to do everything through the terminal) and started preparing examples that he hoped to show during his own livestreams, but the RaspberryPi seems to have crashed, unable to bear the weight of so many examples…

Computer Vision Projects in Java (Processing)

Among other projects during the vacation were also computer vision projects: color sensor, color tracker, motion sensor and motion/ face detection in Java (in Processing), partially Simon’s own code:

 

 

 

Analysis and generation of text-based data. What else to do on vacation?

During the vacation, Simon worked on several programming projects playing with language and grammar, from Daniel Shiffman’s Programming from A to Z course at New York University. Those included creating a new context free grammar sentence generator, using a markov chain in a Google form, creating a diastic machine with JQuery and making a regular expressions tester in JavaScript.
