Actions Runner Controller (ARC) is a tool that helps you automatically manage and scale self-hosted GitHub Actions runners using Kubernetes. It creates runner scale sets that grow or shrink based on how many workflows you are running, making your CI/CD process more efficient and cost-effective. ARC uses containers for runners, so new instances can start or stop quickly and cleanly. You can install ARC easily with Helm on Kubernetes and customize runners with features like custom images, volumes, and scripts. This automation saves you time and resources by matching runner capacity to your actual workload needs[1][2][3].

🪐 Deep in the constellation Draco lies the pulsar PSR J2222−0137, a unique spinning neutron star about 900 light-years from Earth that forms a binary system with a faint white dwarf. PSR J2222−0137 spins once every 33 milliseconds, and its partner is one of the coolest known white dwarfs, so cold that its surface may be made of crystallized oxygen—offering a rare glimpse of two extreme stellar remnants circling each other in quiet cosmic partnership. ✨

🪐 The star AR Scorpii, located about 380 light-years away in the constellation Scorpius, is an unusual binary system where a rapidly spinning white dwarf blasts powerful beams of energy at its red dwarf companion. Unlike typical stars, AR Scorpii pulses in visible light and radio waves every two minutes as its magnetic field accelerates particles, making it the first known "white dwarf pulsar" in our galaxy. ✨

🪐 The star VFTS 352, located in the Tarantula Nebula about 160,000 light-years away, is actually two massive stars orbiting each other so closely that their outer layers touch—creating a rare "overcontact binary." This unusual system is on the verge of merging, and both stars are so hot and bright that their shared atmosphere fuses them together, making VFTS 352 one of the most extreme examples of stellar partnership ever found. ✨

🪐 The exoplanet Kepler-16b orbits not one, but two stars, forming a real-life counterpart to a Tatooine-like world in the constellation Cygnus. This Saturn-sized planet experiences double sunrises and sunsets as it circles both its orange and red dwarf hosts, creating a celestial theater found nowhere in our own solar system. ✨
