The below Python source files control an OLED display (size 96 x 64, 65K colours) using a SSD1331 chipset and the SPI interface. The source code initialises the chipset and includes hardware accelerated functions for drawing primitive shapes and a non-hardware accelerated full ASCII set. Examples include a basic Space Invaders game, and a clock.

What is the appeal of dynamically-typed languages?

Kris Nuttycombe asks:

I genuinely wish I understood the appeal of unityped languages better. Can someone who really knows both well-typed and unityped explain?

I think the terms well-typed and unityped are a bit of question-begging here (you might as well say good-typed versus bad-typed), so instead I will say statically-typed and dynamically-typed.

I'm going to approach this article using Scala to stand-in for static typing and Python for dynamic typing. I feel like I am credibly proficient both languages: I don't currently write a lot of Python, but I still have affection for the language, and have probably written hundreds of thousands of lines of Python code over the years.

The humble cone contains the answers to fundamental questions about the universe. But not _this_ one, its just pixels on the screen. What is mildly interesting about this cone is the way it is generated - a 2D polyline forms the bottom side and hypotenuse of a right-handed triangle in the X-Y plane. This flat shape is then "extruded" into three …

I found myself in a popular electronics emporium recently; I was transfixed by the on-screen advertisements of a certain manufacturer, which seemed to encourage consumer conformity and consistency - and felt driven to reproduce it's iconography crudely here. See
