Hoy tomamos el tren a Múnich con @Ayenkantun para votar mañana las elecciones presidenciales de #chile. Al llegar nos encontramos con un tren arcoiris. Espero que mañana la gente no vote a la extrema derecha ni al facismo y podamos seguir teniendo un Chile democrático y respetuoso con la diversidad.
Un largo tren blanco con una franja arcoiris que se encuentra detenido en la estación. El cielo se ve oscuro y las luces de la estación están encendidas.

A figure showing a graph where nodes are edges use different colors. Yellow, green, and blue nodes represent dynamic elements of the scene, whereas black nodes represent static elements. Red dashed arrows represent edges between different snapshots. Below the figure, there are labels explaining the use of colors for the respective snapshots.

It seems that the ESWC2025 website is not working.

A hummingbird butterfly was flying among the lavender flowers when @Konenpanien and I were on the way to the supermarket this morning. We don't always have the opportunity to see one that stays among the same flowers long enough to film it. It's a pity we didn't have a better camera with us.

Today we were skating with @Ayenkantun on a nice track in Vaihingen. She made a video of me skating. The grass around the track was high, and full of flowers and insects. We discovered a good place to skate.

A screenshot of the paper showing the structures of queries, depending on the links that were seen in training and the links that are missing. Queries are depicted with directed graphs, where missing links are represented with dotted lines and seen links are represented with regular lines.

@skinnylatte Thank you for sharing this story. When I was in Singapore in 2024, I had to read about the Japanese occupation after seeing this mural that was in the top of the Faber mount. The project of saving the oral histories is extremely valuable […]

A relief mural showing the Japanese army entering Singapore, and killing some blindfolded people. A group of planes passes by bombing the city and a military man is standing in front of a committee sitting at a table, in what looks like an act of surrender.

Today @yiyiyiyi gave @Ayenkantun and me some gifts from China. In the pictures, there are moon cakes (to celebrate the Chinese new year). The covering is sweet cake, it is filled with winter melon jam, and in the middle it has a salty egg yolk. A very uncommon combination for us, but very delicious.
A moon cake with a removed piece to show how it is inside. A moon cake where the egg yolk is distinguishable from the winter melon jam. The box with a bitten moon cake. The cover has a relief that appears to be a woman dancing in a dress with Chinese symbols.
