Inside of a Lemur Pro laptop, with the battery removed. The old battery is sitting below the open laptop, where several pieces of tape and foam that used to hold it in remain stuck on. A couple of ribbon cables pass under the area where the battery was.

Inside of the laptop with the new battery installed. The new battery cable is a bit longer than the old one, so has to bend around a bit to meet the connector.

After nearly 2.5 years of daily use, the battery in my #system76 Lemur Pro (lemp12) was running about 50% capacity, so I decided it was time to replace. I ordered a replacement directly from System76, and while it cost a bit more, I'm more confident it's not […]

Plot of a polar equation that forms a sunburst image. 12 main long sun rays each with shorter rays on both sides, fading from red near the center to yellow on the outside.

It's gonna be a bright, bright r = [1/2 + k|cos(6θ)/2| / (1 + 4sin²(24θ)) - sin(48θ)/50]; 0 < k < 2 day!

(aka fun with polar equations)

Manager on Tuesday: For this week's department meeting, we have a guest speaker to talk about boosting your group creativity through brainstorming.

Team on Wednesday: We need to come up with a good name for this new thing we're working on.

Manager: Did you try asking AI?

True story. *sigh* […]

Screenshot of the Konsole terminal emulator running an interactive Python session demonstrating sixelmath. Two lines of Python code are entered: from sixelmath import sixelmath sixelmath(r'\oiint_S E \cdot dA = \frac{Q}{\epsilon_0}') The output shows the rendered equation of Gauss's Law.

Screenshot of the Konsole terminal emulator running an interactive Python session demonstrating use of sixelmath with sympy. Three lines of code calculate an integral: import sympy x = sympy.Symbol('x') result = sympy.integrate(x**2 * sympy.exp(x) * sympy.cos(x), x) The standard result is displayed as: x**2*exp(x)*sin(x)/2 + x**2*exp(x)*cos(x)/2 - x*exp(x)*sin(x) + exp(x)*sin(x)/2 - exp(x)*cos(x)/2 Then, sixelmath is imported and the result displayed again from sixelmath import sympysixel result Which shows the same result, this time rendered in regular mathematical notation.

I made a little extension to my Python-based LaTeX math renderer so it can be used to draw equations and Sympy expressions directly in the terminal as sixel graphics. Install with `pip install sixelmath` and give it a try! (in a sixel-supported terminal, of […]

#genuary31 - Shaders. Here's a fractal animated using shaders. There is a single orbit trap along the imaginary axis, which swings left and right to make the animation. For the original WebGL-rendered version, go to […]

Fractal image with a yellow-orange bug-like shape with purple curves behind.

#genuary30, It's Not a Bug, It's a Feature. Continuing the theme of fractal images that remind me of things - this one of course looks like a bug.

#genuary #genuary2026 #bug

Fractal image of a purple spiky ball with small green and blue rings surrounding it.

For #genuary29, Genetic Evolution and Mutation, no genetic algorithms were used in this fractal, but it always reminds me of a virus, which involves genetic mutations...

A Julia Set fractal in yellow and purple.

This #genuary28 image is made entirely of HTML `<div>` elements, drawn using a short JavaScript that calculates a Julia Set fractal. A screenshot of the page is shown in this post - for the original, go to […]

Fractal image: a green plant-like shape with red "berries" on a tan background.

#genuary27 - Lifeform. This is another fractal with an organic look. It makes me think of some sort of plant encountered by the crew of the Enterprise in Star Trek.

#genuary #genuary2026 #fractal

A pattern of tiled squares of different sizes and a full rainbow of randomly-placed slightly muted colors.

For #genuary26, Recursive Grid, I went with a pretty minimalist pattern where each square is subdivided into 4 smaller squares.

Fractal image: A yellow-green beanstalk-like vine twisting around itself over a blue background.

#genuary25 - Organic Geometry. My favorite fractals are the ones that appear organic, like this one that reminds me of a growing vine.

#genuary #genuary2026 #fractal #beanstalk

A 20 by 20 grid of small squares, with random colors of the rainbow, each square slightly turned and skewed from its "perfect" orientation.

#genuary24 - Perfectionist Nightmare. I explored several ideas for this one, where a regular grid has just a bit of randomness to make it slightly "off". The result reminds me of the tiles in my bathroom.

#genuary #genuary2026 #tiles

A Mandelbrot Set fractal with blended orange, red, green, and blue patterns due to transparency of the orbit traps.

The #genuary23 prompt is Transparency. Applying a transparency channel to a otherwise typical orbit trap fractal leads to some interesting effects. Might need to explore this one more later.

Three overlapping spirals, enclosed in a single circle, with three smaller circles filling the gaps.

I've often been tempted to get a pen plotter, but haven't quite taken the plunge. For #genuary22 I did some experiments with overlapping Archimedean spirals, that could eventually be used with a pen-plotter. I find the spirals interesting since their radius […]

A grid of circles in red, blue, yellow, and green, where some circles have squared corners extending them to teardrop shapes.

For #genuary21, "Bauhaus Poster", I attempted to reuse typical Bauhaus color theme and shapes, applying texture with SVG filters.

A dark blue path on paper-texture background traces a complex curve.

This #genuary20 "One Line" artwork is made of a single line fractal.

A grid of yellow dots surrounded by swirling blue and pink lines.

For, #Genuary19, a 16 x 16 grid of points is iterated through the Mandelbrot fractal equation and the paths of the points traced with smooth curves.

#mandelbrot #genuary #genuary2026 #fractal

For #genuary18, the prompt is an unexpected path that follows a very simple rule. My "simple" rule returns to the concept of "odious numbers": if ⌈x⋅y⌉ is odious, turn 60 degrees counterclockwise. Otherwise, turn 60 degrees clockwise. Here, three paths with […]

Interlocking purple and turquoise curves repeat in a regular tile pattern.

For #genuary17, this pattern uses Wallpaper Group pmg (22*), with tiles containing arbitrary Bezier curves.

Fractal imagery, an orange diamond grid on top of a swirling brown, blue, and green distorted swirling version of the same grid.

Many fractals exhibit macro-scale order with micro-scale disorder, perfect for #genuary16 "Order and Disorder". The top layer is the most ordered, with entropy increasing as you go down.

A hexagon filled with wandering black-and-white curves and circles filling the space.

Today's #genuary prompt seemed perfect for a Truchet tiling image, where the curve perfectly fills the space.

#genuary2026 #genuary14 #truchet #hexagonal

Pencil-like drawing of a face.

Parametric equations used to generate the face. Each equation for x and y is a function of parameter t with various sine and cosine coefficients.

My #genuary13 self portrait is defined entirely by parametric equations! Portrait in the first image, equations in the second. The equations were generated by tracing points from a photograph, then basically using an FFT algorithm to convert the coordinates […]

Thin yellow and purple lines radiate from a central square, ending in small circles. The lines form the diagonal of faint thin gray rectangles.

This is probably an unexpected interpretation of #genuary12, "Boxes Only", but I like how it turned out. Thinking of different uses of the term "box" in mathematical contexts, somehow I recalled the Box-Muller transformation, named after George E. P. Box and […]

An image of made of python code written from to bottom, fading from purple to orange to yellow, each line along a random overlapping curve hanging from the top of the image like an upside-down fire.

Very similar to my interpretation of last year's Genuary 3 "42 Lines of Code" (link below), this code is a "Quine" that outputs itself into a stylized image using SVG curves and gradients.

A cloud-filled sunset. The dimly-lit foreground has cholla cactus and juniper covered with a bit of fluffy snow. Faint city lights of Albuquerque are starting to appear just below the horizon line.

Snowy New Mexico Sunset.

For Genuary 9, a crazy automaton, I'm combining a cellular automaton with the concept of "odious numbers" I learned about during #mathober. Each cell is assigned one of 4 states, and if sum of states of 8 surrounding cells is an odious number, increment the […]

A cartoonish city skyline made from yellow rectangles in the foreground, green rectangles in the middle, and purple rectangles behind, each with black and yellow windows filling their area. A dark blue sky with scattered white dots for stars falls behind.

This is a (very slight) extension of last year's Genuary20 (Architecture) prompt, which I based on the skyline in the old QBasic Gorillas game. This year, it gets extended to "3D" with layers of buildings, scaled and "misted" toward the back. And stars in […]
