  • The Sunlight

    This place has no rain. Nothing to block the suns above it. Just a baked hot surface, scarred by the thermal stresses of the heaving that occurred prior to the falling of the system into this configuration. Luckily, without an atmosphere, all I need is a wide, reflective parasol and more patience than our forebearers…

  • 3D Printing

    I am not new to 3d printers. In college I helped to run the 3d printing lab, fulfilling requests to make things for various classes(at the time, the most promising was how it could be used to demonstrate anatomy with relatively cheap modifiable parts). That was around 2017. At the time the printer lab consisted…

  • Rich and Warm and Light and Toxic

    The sun is warm and the air is humid. The sky is a rust color overhead, it’s not a very friendly atmosphere, but hospitable enough as a facsimile. Beneath the toxic atmosphere an ecology of immense volatility blossomed and sputtered and fell prey to the sort of cycles that ecosystems have that degrade their condition…

  • Navigation failure

    The darkness between the stars is very cold. And here I sit equidistant between a star and its companion matter sphere that cannot rightly be called a star as it is practically beyond fusion. It shines like a beacon, a cleansing swath of light and harder stuff and power that I can only just survive,…

  • Returning to simple-dots-game after a while

    It has been a while since I worked on this game. And after being away for a while, I can’t really see the sources of frustration that I felt before. They were probably residual feelings from the frustration of getting it to a functional state and figuring out the system. But there’s something that was…

  • Initial impressions of Orbtk

    I’ve been meaning to get into rust for a long time, but there were some pieces missing from the ecosystem(good rust bindings for GUI applications appear to be hard to come by), but rust isn’t like most of those other languages, it requires a different approach because many of the gui frameworks that have worked…

  • FFMPEG input/output as an abstraction

    I am currently working on writing code to support the usage pattern that I have used in the past for making animations using ffmpeg to encode video. Really though, how complex does it need to be? Well, let’s put together a wish-list: It should always shut down the pipe at the end of executionIt’s really…

  • L-Systems with shapes

    Rendering shapes is a relatively small addition to the L-System code I’ve been implementing over the last few weeks, it consists of a few manual dispatches to drawing code based on the first symbol in a sublist. The immediate alternative is using defgeneric and the common lisp object system, which is probably the correct thing…

  • Improving On L-Systems

    The simplest implementation of L-Systems requires term-rewriting, and maybe turtle graphics. We already have arbitrary computation on the execution end, but what if we could add computation on the term rewriting phase? We can get a lot more flexibility without adding an infinite number of rules. Also the last L-System post has had its code…

  • 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…

Ad-blocker not detected

Consider getting an adblocker because you don't need anyone to fill your brain with garbage, or to execute code on your local machine.

For firefox, I would recommend uBlock origin

For safari I personally use AdGuard.

For Google Chrome, I suggest not cementing google's stranglehold on the internet, but otherwise I believe uBlock origin still exists for it. Idk manifest v3 was not a great choice for adblocking software
