Idk, games I guess
I grew up during that period when newgrounds was a major media site. A lot of the games were not very good, especially the one I made with a pirated adobe flash CS3. But hey, the score was your health and that was something that someone called “An unusual mechanic” which is the closest to…

Some Thoughts on Codex, a Common Lisp Documentation Tool
Codex is one of a small number of native documentation generators in lisp. It uses an unusual markdown format called Scriba. I have been using it to document img-genner since about 2 years ago. In those two years there hasn’t been an update for it(Actually for at least 7), but that’s not terribly uncommon among…

L-Systems
L-Systems are a type of fractal, well, that’s not really true; L-systems are a formalism for constructing rules for iterated systems, such as plant growth and turning those into images. But what’s interesting is that they’re actually remarkably simple to implement the evaluation of. So let’s look at one of the simpler ones, the binary…

Particles Tunneling Through Solid Earth
No, I’m not going to write about neutrinos, or anything else that is ‘real’. Pixels are the particles of today’s post. Their universe is very different than ours, it is solid in all directions, it is quantized(at a different level than ours). At each moment, there are a countable number of choices. To be a…

Timetracker
One of the other projects I’ve worked on, the one I’m not sure I’ve talked about here has been the timetracker tool. What it provides different than others that I have found is that it doesn’t ask what you’re doing, it just reads the window you’re using and files it away for later, along with…

Recreating an old Visualizer I swear I saw
I have vague memories of a visualizer that I will likely never encounter without looking for it again. It was a waveform display but it had these rectangles that would ride them like boats, not really like surfing. Now, you might be wondering why I’m doing this when my library creates, at best, video. Well,…

img-genner Switching away from cl-png
cl-png is a long lived package that mostly works, but it contains a single flaw, it relies on the presence of a library and the competence of the implementation in getting to it. It grabs the source and tries to build it. That’s one reason that I don’t much care for it. As much as…

Rescaling Video Using img-genner
There’s not much of a reason to do this because ffmpeg has a much faster and nicer scaler, but maybe we want to write common lisp to handle an effect. When I introduced img-genner, I wasn’t sure that this was the direction to take, but now it seems appropriate, if nothing else. You will most…

Animating direct to mp4 with img-genner
Two posts ago I started talking about img-genner. Guiding my authorship of the library by using it. Today I made a change that allows for what I think are exciting possibilities. One of the best uses I’ve found for this library has been using it to generate animations, surprisingly I’ve started to take a liking…

Drawing with img-genner
I talked about img-genner’s glitch functions last time. Now you get to see the messier part of the library, as of (january 15th 2022), the part that needs refactoring and reconsideration. For one thing it is enormously picky in terms of types. So much so that much of the code broke regularly with only slightly…
