Und wieder eine "neue" alte Sprache gelernt. Fortran77. Ich versuche gerade die Cray Y-MP EL etwas zu kitzeln.

Also mal das Traveling Sales Person Problem mit 23 zufälligen Städten mit asymmetrischen Gewichten testen:

The Belgian association #PFT #TSP used to organise, and probably still organises, railfan specials that included a number of photo stops en route. On this picture, taken in the #Gent area in May 2008, we see such a charter train hauled by two “round nosed” #AFB #Nohab diesels.

The beautiful train station of #Binche in June 2004: photo taken on the occasion of a railfan event, organised by the Belgian rail enthusiasts association #PFT #TSP, to say farewell to #SNCB #NMBS Classes 22 and 25. This is the day’s charter train with two Class 22 electrics leading.

What could be a scene on a rural #SNCB #NMBS Belgian railway line of the 1980s, is actually a picture taken on the occasion of a railfan event in August 2005: railcar 4403 crosses a bridge of the Chemin de Fer du Bocq museum line, operated by the #PFT #TSP enthusiasts group.

'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.' https://www.tagesspiegel.de/berlin/ort-wurde-bis-zuletzt-geheimgehalten-rechtsextremist-martin-sellner-halt-lesung-in-berlin-wilmersdorf-13289212.html /via #tsp #checkpoint

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.
