'Martin Sellner sei der „einzig legitime Grund für einen Abschiebeknast“, hieß es auf einer Gegendemo, die sich spontan vor den Räumlichkeiten des Lokals versammelt hatte. Der Rechtsextremist solle sich zurück nach Österreich „verpissen“. Anwohner, darunter auch unmittelbare Nachbarn des Lokals, sowie Passanten solidarisierten sich mit dem spontanen Protest gegen das rechte Treffen.' tagesspiegel.de/berlin/ort-wur /via #tsp #checkpoint

Comparing a naive "nearest neighbor" #TravellingSalesmanProblem solver with a #2optSwap one, adding a #DelaunayTriangulation mesh, it shows how often the better solution falls into the triangulation!

The #py5 sketch is interactive, you can generate other random nodes and move them around dragging with the mouse.

He was riding his #foldie #bike when the frame broke. He's alright. Happened at a small interior road, not on a major busy street. And he had his helmet on.

Some blamed the allegedly poorly done welding. I blame the rather thin alloy and our poorly paved roads that cause lots of stress to #bikes & #cyclists. 🚴

Sunday morning #bike ride 🚴

I rode out while it was still dark and headed for city hall. It was lively, with some #cyclists coming together with their bike groups and wearing their group jerseys.

There was a large banner and, as expected, everyone wanted their #photo taken. I don't think those guys even know each other, but the way they handed each other their phones and graciously took photos for each other... Aaaww 😊
