The Commander X16 has a built-in assembly environment that doesn't get much attention. This is a quick demonstration of how to use it. 00:00 Intro 00:20 BASIC 01:13 Assembly with C-String 07:07 Assembly with P-String

This is my first participation in the the long tradition of making Holiday Demos for 8 bit computers. This demo uses raster line interrupts to scale a tile map larger and larger as the beam travels down the screen. The result is an effect that is reminiscent but not quite accurate to the "Mode 7" rotations that were possible on the SNES console. Combined with a bitmap and some sprites on the to...

This is a explanation and demonstration of how my custom VERA tools can be used not only for graphical tiles and tile maps, but also used create the data needed for collision detection on the Commander X16. Using these tools, you can create a game-engine-like development environment when creating your own Commander X16 Games. Tools: github.com/jestin/gimp-vera-tileset-plugin github.com/jestin/t...

This is a quick and dirty from-scratch demonstration of some tools that I've created for the Commander X16 Retro computer, or really any computer that uses the VERA chip for graphics. Using these tools, you can quickly get started developing graphic resources, and even incorporate the "building" of resources directly into your project using a Makefile. Feel free to download these tools, try the...

I watched a video (th-cam.com/video/xGmXxpIj6vs/w-d-xo.html) where a guy wrote snake in under 5 minutes. I thought some of the code needs explanation for novices, so I made this video to explain it. I hope this helps someone.

This is a video of how I made a simple animation of a 2D character with Blender. I'm not sure if this is the best way, or even the most practical for what I want to accomplish, but I figured I'd share what I learned anyways. I apologize for the poor sound quality, but my usual headset was not working properly.

I've been working on my SQRL library at github.com/jestin/SqrlNet/, and I just got full login functionality working! This is very preliminary, but it serves as a good proof-of-concept for the system as a whole. The client application is written in GtkSharp, and the server is written in ASP.NET MVC using MongoDB as a database. For those who don't know, SQRL is an proposed standard for secure log...

This is a demo of my progress on an SQRL client I've been writing. For those who don't know, SQRL is a secure login system that doesn't require usernames or passwords, but rather QR codes and public key cryptography. For details see www.grc.com/sqrl/sqrl.htm. For my own implementation, go to github.com/jestin/SqrlNet.

This video shows some fundamental differences between a C program, and a C# program. It's not very useful for helping you learn to write code, but it is important to understand how C# works.

After one month of growth, our hydroponics system is working. Some plant are doing better than others, and the plants we grew from seed are doing great!

I followed the wonderful tutorial here: th-cam.com/video/CVPcT0dJmoY/w-d-xo.html, except I used an object I created in OpenSCAD for 3D printing purposes. The background video was shamelessly stolen from the creator of the above tutorial (so give him some link love), but the model is all mine. Bonus: To see a real physical version of this object, check out my other video: th-cam.com/video/DcrxUf...

This is our most recent progress on our basement hydroponics system. We have added the chemicals, potted the plants, and are starting new seedlings for later.
