Show HN: Paintpot – Kid-friendly MSPaint clone for Linux

Most of the alternatives diverged from the true fun of MSPaint that I had as a child. My children also seem to enjoy this. The closest existing project was "Drawing" on Linux, but I felt it couldn't decide if it was a vector or a raster editor, and this confused my kids, and made good fill pours difficult.Features added beyond original Paint: - Draw circles starting from the center. - OKLCH Palette - Visible pixel grid when zoomed in. - Builds on Linux and Windows. - Written in rust.

SyncVid: World-Equivariant Diffusion for Synchronized Video Generation

arXiv:2610.31765v1 Announce Type: new Abstract: Generating multiple videos of a dynamic scene from a single reference video requires synthesizing both observed and unobserved content consistently across viewpoints. Existing camera-control methods for video diffusion typically rely on architectural mechanisms, including camera embeddings, cross-view attention, and geometric conditioning. Although effective for static scene content, these approaches often struggle with the fine-grained, dynamic geometry that must remain coherent across views and over time. We synchronize the diffusion process itself by sampling the Gaussian noise prior in a canonical 3D space derived from the source video and rasterizing it into target cameras, rather than sampling independently in each 2D image plane. Our m
