WebAssembly and SDL graphics exampleFeb 3, 2023, 5:56 p.m.
I have been playing around with WebAssembly a bit. I set an example up that draws balls bouncing around the canvas using SDL. The code is at https://github.com/ranton256/wasm_bounce and you can see it in action on this page.
Tech Job Searching and Interviewing ResourcesJan 19, 2023, 9:06 p.m.
Given the large number of recent technology industry layoffs and general economic conditions I put together an article with advice and resources for interview preparation and job search to try and be of some utility.
Some OpenGL ProjectsJan 7, 2023, 2:50 p.m.
I have been working on some OpenGL projects lately. One is a setup tutorial for Macs for Xcode using glfw and glew. The setup is always a bit fiddly to me and has changed since the last time I went through it, so I created a separate GitHub repo for just the setup part and a small spinning triangle. It's available at https://github.com/ranton256/mac_opengl_setup_example
The second project is more interesting. I just wanted to get a relatively decent rendering setup going with some actual mesh models. I reused the SMF reading code from some grad school projects to load a few more interesting objects, and also coded in mesh generation for cubes, spheres, and pyramids. It uses Blinn-Phong shading and texture mapping. Several of the textures are generated procedurally using Perlin noise or a checkers pattern and several are loaded from PNG files. The libpng loading code is self-contained and probably useful to others.When I have some time to return to this I would like to add shadows and environment mapping of some kind to make it more complete. You can check out the code and screenshot at https://github.com/ranton256/opengl_rendering_demo
Effective Developer TeamsDec 26, 2022, 2:35 p.m.
During the holidays I wrote up some of my experiences and thoughts on how to run effective developer teams, mostly focused on testing, CI/CD, and using reviews and transparency to promote a culture of learning. It's available on LinkedIn at Strategy for Effective and Efficient Developer Teams
Algorithms and FractalsDec 16, 2022, 7:35 a.m.
In order to show how fun (and visual) algorithms can be, I pulled together some visual examples and code for some of my favorite fractals
Timmy, Cave ExplorerDec 7, 2022, 5:11 p.m.
I finally got around to sharing the game I created with my kids a few years ago. It's a simple space invaders style game written in Python with Pygame Zero to help them learn about coding. We also used PyInstaller to create a distributable version. The binaries are in itch.io at https://ranton.itch.io/timmy for Mac and PC, and the source code is on GitHub at https://github.com/ranton256/timmy. I also put the lessons I wrote for them on programming, Linux, and Python up in a separate GitHub repo, https://github.com/ranton256/python_lessons. Hopefully these are useful to other beginners.

Ray Tracing FunOct 14, 2022, 11 a.m.
I recently took a course, CS 636, at Drexel on advanced rendering techniques. The project work was focused on ray tracing which was quite fun. You can see my final results and links to more information at Ray Tracing page.
Epictetus and the EnchiridionJun 5, 2022, 11 a.m.
I started a site recently to play around with Ghost CMS a bit, and for something of interest content wise I decided to make it about philosophy and inspirational quotes. This morning I wrote a short article around Epictetus, my favorite Stoic philosopher. I hope others will find it helpful. Stoicism has brought me some measure of peace and calm over the past few years.
