Hydra vs PUSH Video Wallpaper

Hydra is a continuous integration service for projects based on Nix. It checks out project source periodically or continuously, builds it, runs tests, and produces reports. Work is organized into jobsets whose inputs can trigger builds when they change; jobsets can also depend on one another. Flake jobsets are supported when their outputs expose a hydraJobs attribute set. Jobs can produce packages, ISO images, or tarballs, and jobset inputs can use Git checkout sources. Hydra also provides a JSON API. It is aimed at Nix and NixOS package developers, not people who only need to use NixOS. Hydra is open source under GPL-3.0 and listed at free. It is self-hosted, with no hosted option listed, and running it is currently supported only on NixOS; the repository recommends the NixOS module for production. Flake evaluation is restricted from accessing files outside the Nix store. Some state is stored in the database, so backups are needed, and the wiki reports that hydra-queue-runner can sometimes leave queued builds unscheduled.

PUSH Video Wallpaper is a Windows app for placing videos, animated GIFs, or YouTube clips on the desktop and using videos, animations, images, or YouTube clips as a screensaver. Supported media includes MP4, GIF, WebP, images, YouTube, and direct video URLs. Playlists can draw on local files, folders and subfolders, ZIP archives, YouTube links, and YouTube playlists. Controls include alignment, playback speed, looping, per-item duration, anti-aliasing, and default YouTube quality. For multiple monitors, users can duplicate or extend video, assign separate playlists, turn monitors on or off independently, or stretch one playlist across screens. The app can pause during fullscreen games or video playback, reduce activity on battery, or stop rendering to free resources. The product page says no internet connection is needed after setup. It requires Windows 10 or 11 and at least 2 GB RAM, with a GPU recommended. The free version costs nothing and enables all features, but displays a watermark. Paid perpetual licenses are for non-commercial use and include free updates for future versions.
