Das ist ja fast beleidigend, dass jetzt ausgerechnet die Grünen wegen Polizei-kritischer Bekleidung einen Skandal im Bundestag haben. Hunderte Linke fühlen sich schon wieder nicht gesehen.

Cooling our old house in summer. This house was built in 1940 so it has gone through all the stages and types of heating you can probably imagine.
We installed a ductless ("air source") heat pump a few years back. This was a revelation after 15 years of "window management" and fans to keep a lid on the intense heat of the Alberni Valley.
It has made a wonderful difference both for cheaper heating in winter and newfound cooling potential in summer. We only could get one big enough for two of three floors.
So basement and main floor have a register like this.
Today, on the first official hot day of summer it is:
Outside temp: 33°C
Top Floor (windows open, fans on): 30°C
Main Floor (windows closed HP set to 23°C): 25°C
Basement (HP set to 23): I would estimate 23°C
We also have a hybrid HP/Electric hot water tank in the basement that I have blowing its outlet air into the room for summer to help keep the temperature down in the basement.

Geometric Visual Servo Via Optimal Transport
When developing control laws for robotic systems, the principle factor when examining their performance is choosing inputs that allow smooth tracking to a reference input. In the context of robotic manipulation, this involves translating an object or end-effector from an initial pose to a target pose. Robotic manipulation control laws frequently use vision systems as an error generator to track features and produce control inputs. However, current control algorithms don't take into account the …

Polyhedral coproducts
Dualising the construction of a polyhedral product, we introduce the notion of a polyhedral coproduct as a certain homotopy limit over the face poset of a simplicial complex. We begin a study of the basic properties of polyhedral coproducts, surveying the Eckmann-Hilton duals of various familiar examples and properties of polyhedral products. In particular, we show that polyhedral coproducts give a functorial interpolation between the wedge and cartesian product of spaces which differs from the…
