[$] Improved load balancing with machine learning

The extensible scheduler class ("sched_ext") allows the loading of a custom CPU scheduler into the kernel as a set of BPF functions; it was merged for the 6.12 kernel release. Since then, sched_ext has enabled a wide range of experimentation with scheduling algorithms. At the 2025 Open Source Summit North America, Ching-Chun ("Jim") Huang presented work that has been done to apply (local) machine learning to the problem of scheduling processes on complex systems.

15 Years of OsmAnd

The OsmAnd map and navigation app project recently celebrated its 15th anniversary.

All these 15 years can be roughly divided into three stages. For the first five years, we built the very basic functionality—offline maps and navigation that just worked. Over the next five years, we transformed OsmAnd into a full-fledged application with plugins, extensive settings, and professional tools. We dedicated the third five-year period to deep internal work: completely rewriting and improving key components like the rendering engine and routing algorithms.

Now, a new, fourth stage begins. We have reached functional maturity, and our main goal for the near future is to polish what we've already built. We will focus on stability, speed, and consolidation. User expectations are growing, and what was once considered normal must now be flawless.

Moonlight Peaks: your chance to live as a tiny vegan vampire

Dracula’s daughter seeks a more peaceful life making plant-based blood substitutes in this Stardew-Valley-inspired, gently creepy farming game

What if you were a tiny, vegan vampire? That’s the question posed by Moonlight Peaks, the gen Z-coded, achingly TikTok-ready supernatural life sim. Inspired by the popularity of “cosy games” such as Animal Crossing and Stardew Valley, Moonlight Peaks drapes you in the cape of Dracula’s daughter, who has fled her father’s corpse-ridden home to start a new, peaceful life.

Soon, she settles among werewolves and witches in the supernatural farming town of Moonlight Peaks, where she grows crops and rears animals instead of subsisting on the blood of innocents. Both cosy and creepy, the game has you creating your own plant-based blood substitutes, befriending the town’s residents and fixing a whole host of problems left in daddy Dracula’s wake.

Moonlight Peaks is out on PC in 2026

Tech firms suggested placing trackers under offenders’ skin at meeting with justice secretary

Exclusive: Shabana Mahmood told companies she wanted ‘deeper collaboration’ to tackle prisons crisis

Tracking devices inserted under offenders’ skin, robots assigned to contain prisoners and driverless vehicles used to transport them were among the measures proposed by technology companies to ministers who are gathering ideas to tackle the crisis in the UK justice system.

The proposals were made at a meeting of more than two dozen tech companies in London last month, chaired by the justice secretary, Shabana Mahmood, minutes seen by the Guardian show. Amid an acute shortage of prison places and probation officers under severe strain, ministers told the companies they wanted ideas for using wearable technologies, behaviour monitoring and geolocation to create a “prison outside of prison”.
