Kevin Moerman 🔓🦿<p>How am I supposed to get any work done when the maths is so pretty! Look at it flutter by like a butterfly! </p><p>This is an animation for "biharmonic spline interpolation" (see also: <a href="https://doi.org/10.1007/s11004-011-9346-5" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">doi.org/10.1007/s11004-011-934</span><span class="invisible">6-5</span></a>). </p><p>I'm testing a Julia implementation here which I'd like to use to interpolate the Z-coordinate for meshes that should span a closed curve domain where the x,y, and z are known. Here I created a circle and manipulated the z-coordinates using z=sin(x+a) where a is a phase offset. Next I animated the change of the phase offset to create the wave like motion. </p><p><a href="https://fediscience.org/tags/geometryprocessing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>geometryprocessing</span></a> <a href="https://fediscience.org/tags/JuliaLang" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>JuliaLang</span></a> <a href="https://fediscience.org/tags/Comodo" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Comodo</span></a></p>

Robin Tarsiger<p>Stumbled across a neat blog post. Nice tutorial-y bit on why people might like the (what I think of as) CLOS style of generics not owned by classes plus multiple dispatch!

Javier 🖖🏃‍♂️🌻🟥🟨🟪<p>Para no gastarme 400 €, estoy mirando emuladores de MSX.</p><p>Me ha dejado 😳 el enterarme que en Japón salió al mercado MSX-Basic Kun. Permitía marcar secciones de código dentro de un programa en Basic. Al ejecutar el programa, compilaba esas partes y ejecutaba el programa con lo que se ganaba mucha velocidad sin tener que hacer prácticamente cambios. Comodidad del basic y rapidez del programa compilado, ¡décadas antes de Julia!</p><p>A ver si puedo probarlo. </p><p><a href="https://mastodon.social/tags/msx" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>msx</span></a> <a href="https://mastodon.social/tags/julialang" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>julialang</span></a></p>
