On Fri Mar 15 2024, use coupon code go-fly-nix to get $50 of Fly.io Credits for new accounts. Xe Iaso discusses Nix, a powerful Docker image builder. Nix’s unique language simplifies package building and OS image creation. While Docker is popular, its non-deterministic builds and wasted space issues are problematic. Nix fixes this by focusing […]
LWN.net is seeking subscribers to support the publication. Richard Stallman is rewriting Elisp in Emacs to simplify and reduce the cognitive load, proposing a new macro, cond*, as an alternative to pcase. The discussion has sparked debate over the need for a new feature, with concerns about documentation and potential code churn. Stallman wants to […]
On March 14, 2024, Ollama announced support for AMD graphics cards in preview on both Windows and Linux. This means that all the features of Ollama can now be accelerated by a variety of AMD graphics cards, including the Radeon RX and PRO series, as well as Instinct accelerators. Currently supported cards include the Radeon […]
Georgetown University Medical Center neuroscientists found that the anterior neostriatum within the basal ganglia is abnormal in children with developmental language impairments, potentially improving diagnosis and treatment. The condition affects language development and is as common as ADHD and dyslexia, more prevalent than autism. The researchers’ analysis of brain abnormalities in people with the disorder […]
Physicists have discovered a new way to combine quantum physics with gravity after four decades, known as “Post-Quantum Gravity” by Johnathan Oppenheim. This theory reconciles quantum physics and gravity without needing dark matter or dark energy. Oppenheim’s approach involves combining randomness into gravity, leading to unique contributions similar to MOND and even dark energy. While […]
“Algorithms for Modern Hardware” by Sergey Slotin is a forthcoming book targeting everyone from performance engineers to undergraduate computer science students seeking practical ways to optimize programs beyond traditional algorithms. Available on GitHub, the book covers various topics including computer architecture, SIMD, and pipelining, offering case studies achieving significant speedups. The author highlights a shift […]
In this research, the authors investigate and mitigate Speculative Race Conditions (SRCs) on shared resources in operating systems, highlighting vulnerabilities like concurrent use-after-free due to synchronization primitives. They introduce GhostRace, focusing on speculatively executed code paths, revealing that common synchronization primitives can be bypassed using a Spectre-v1 attack, leading to information leakage. They also introduce […]
