After a recent *terrible* first attempt at using matrix as communication platform for our rather big measurement campaign in summer, I just tried selfhosting Mattermost, and boy is it a smoother experience. It's as if it was made for team collaboration, funny eh 😅
Also my first time trying out nixos-containers, very nice to encapsulate or group services together independently of your host NixOS.

Now this was a gorgeous cycling loop. Temperature was around freezing but luckily just few wind. As you see, the weather was ace. Clouds and fog stayed in the north 🌞
Also tried Knee warmers, which was just right! A very good buy!
I just need a solution against freezing toes. @… ,I bought neoprene toe warmer! The shoes are just a bit tight then, …

This image captures a stunning panoramic view of a picturesque town nestled in a valley, surrounded by rolling hills and majestic mountains. The sun is shining brightly in the clear blue sky, casting a warm glow over the entire scene and creating a lens flare effect.

In the foreground, there is a grassy hillside with a few scattered trees and rocks, adding texture and depth to the landscape. The town below is quaint and charming, with clusters of buildings, including a prominent church with a …
This image captures a serene winter scene of a partially frozen lake under a clear, bright blue sky. The sun is shining, casting a soft light over the landscape and creating a peaceful atmosphere. The surface of the lake is mostly frozen, with patches of ice and small areas of open water reflecting the sunlight.

In the foreground, there is a grassy area with dry, brownish vegetation, leading to a wooden walkway that extends along the shoreline. The walkway adds a touch of human presence to the…
This image features a self-portrait of a cyclist taking a break during what appears to be a winter ride. The cyclist is wearing a helmet, sunglasses, and a black face mask, likely for warmth and protection against the cold. They are giving a thumbs-up, indicating a positive and enjoyable experience.

The background showcases a beautiful outdoor setting with a green, open field that stretches out into the distance. The field is bordered by a line of evergreen trees, adding a touch of natural bea…

Abstract: Recent reconstruction methods based on radiance field such as NeRF and 3DGS reproduce indoor scenes with high visual fidelity, but break down under scene editing due to baked illumination and the lack of explicit light transport. In contrast, physically based inverse rendering relies on mesh representations and path tracing, which enforce correct light transport but place strong requirements on geometric fidelity, becoming a practical bottleneck for real indoor scenes. In this work, we propose Emission-Aware Gaussians and Path Tracing (EAG-PT), aiming for physically based light transport with a unified 2D Gaussian representation. Our design is based on three cores: (1) using 2D Gaussians as a unified scene representation and transport-friendly geometry proxy that avoids reconstructed mesh, (2) explicitly separating emissive and non-emissive components during reconstruction for further scene editing, and (3) decoupling reconstruction from final rendering by using efficient single-bounce optimization and high-quality multi-bounce path tracing after scene editing. Experiments on synthetic and real indoor scenes show that EAG-PT produces more natural and physically consistent renders after editing than radiant scene reconstructions, while preserving finer geometric detail and avoiding mesh-induced artifacts compared to mesh-based inverse path tracing. These results suggest promising directions for future use in interior design, XR content creation, and embodied AI.
