Linux 7.0 Cuts PostgreSQL Performance in Half

An AWS engineer reported a significant drop in PostgreSQL throughput on Linux 7.0, with performance reduced to approximately half of its previous capability. Benchmark tests showed that the removal of the PREEMPT_NONE scheduling option was the main cause of this regression. On a 96-vCPU Graviton4 instance, throughput measured at just 0.51x compared to earlier kernel versions. Salvatore Dipietro from Amazon/AWS conducted benchmarking analysis of PostgreSQL 17, revealing that Linux 7.0 delivered only 0.51x the throughput of its predecessors. The root cause was traced to kernel commit 7dadeaa6e851, which eliminated PREEMPT_NONE as the default option, leading to increased contention due to the new PREEMPT_LAZY model. Profiling data indicated that 55% of CPU time is consumed by spinning in PostgreSQL’s spinlock, causing significant performance degradation. When a revert patch was applied, throughput rebounded to 1.94x the baseline. The decision to restrict preemption modes in Linux 7.0 aimed to address issues within the kernel's scheduling model. Dipietro proposed a patch to restore PREEMPT_NONE, but kernel developers suggested PostgreSQL adopt the rseq time slice extension instead. Database operators running PostgreSQL on Linux face potential performance reductions with the upgrade to Linux 7.0.

Age of Empires 4’s next chapter tests your will to survive as the “ruthless” Jin Dynasty arrive

The Age of Empires 4 DLC titled "Yue Fei's Legacy" introduces the Jin Dynasty as a new faction, characterized as "fast and ruthless."

IAEA Launches Global Student Challenge to Design Sustainable Uranium Mines Using Minecraft

The International Atomic Energy Agency (IAEA) has launched a global competition for university students to design and simulate sustainable uranium mining operations using the Minecraft Education platform. Teams of two to four members must create a comprehensive mining system that includes ore extraction and yellowcake production, incorporating advanced technologies such as robotics, smart sensors, and optimized processes. Submissions are due by 1 July 2026, and the winning team will present their project at the International Conference on Fuel Supply Chain for Sustainable Nuclear Power Development in Vienna, Austria, from 13–15 October 2026. Participants must submit an entry form, a university enrollment confirmation letter, a 5–7 minute video demonstrating their mining concept, and a sustainability commitment statement. The competition aims to inspire students to pursue careers in uranium exploration and mining amid rising global demand for nuclear energy. Modern uranium mining is increasingly adopting technologies to enhance safety and minimize environmental impact, with a focus on efficiency and sustainability.
