Want easy capsense touchpad buttons? Just a PCB & 4 resistors. Coming soon to my Tindie store! If you want to make your own, files are here: https://github.com/todbot/touchpads
This demo in CircuitPython but also works in Arduino w/ my TouchyTouch lib

Ukraine says it destroyed 2 Russian Mi-8 helicopters, tugboat in occupied Crimea, shares footage: https://benborges.xyz/2025/09/01/ukraine-says-it-destroyed-russian.html

need to find a way to put #XFCE Terminal tabs at the bottom. it's a terminal: I spend all my pointer focus at the bottom and the tabs on the ceiling are a long way for a thumb on a touchpad 😅

Esqueci meu mouse em casa. O que é terrível, pois eu detesto usar o touchpad do notebook.

The Geodesic Restriction Problem for Arithmetic Spherical Harmonics
Given a Riemannian manifold $M$ and an $L^2$-normalized Laplacian eigenfunction $ψ$ on $M$ with eigenvalue $λ^2$, a general problem in analysis is to understand how the mass of $ψ$ distributes around $M$. There are different ways to attack this problem. One of them is to analyze the $L^p$-norm of $ψ$ restricted to a submanifold of $M$. Here, we concentrate on the case $M=S^2$, $p=2$, and we restrict to geodesics of the sphere. Burq, Gérard, and Tzvetkov showed, for $γ$ a geodesic of $S^2$…

On Atiyah-Segal axioms for Witten-type TQFTs
In this paper, we propose a new definition of the trace-map bordism within the Atiyah-Segal framework for Witten-type TQFTs constructed from the topological twist of mass-gapped theories. We demonstrate that these Witten-type TQFTs are unitary under this revised definition and conjecture the self-consistency of the modified bordism category.

ALNS for Tugboat Scheduling in Inland Waterway
This paper focuses on the barges shipping problem, also known as the tugboats scheduling problem, within the context of a scenario where a single tugboat has the capacity to tow multiple barges and conduct multiple trips in a drop-and-pull mode during a daily work shift. The problem is mathematically formalized as mixed-integer programming models. To tackle real-world-sized problem instances, an adaptive large neighborhood search (ALNS) algorithm integrated with a decoding mathematical model is…

Had a 45 rpm record of this as a kid. Just about wore it out. I still know all the words.
