@prospectmagazine.co.uk admirably and hilariously merciless in their daily email this afternoon.

A poor forecast app. The Met Office, who are the only people running a high resolution forecast for the UK do not show this weather.

Not at all what the Met Office is showing. Different forecasts really are of different quality. Only the Met Office runs a high resolution model over the UK. The Met Office app really is more reliable.

My son has moved up from a 1/16 to a 1/8 double bass, so I made a custom mod to be able to transport the new beast by #cargobike.

I'm in Kigali, Rwanda this week teaching finite element and Firedrake at the African Institute of Mathematical Sciences. The students are incredibly sharp and attentive. It's a pleasure to teach here.

Looks even more like the end of the punting pole on the Valk (Falcon) used to this day in the shallow lakes of Friesland. Pole on the starboard shroud in this image.

Everyday cargo bike use: using a cargo bike to fix city bikes. Such a nice sight.
