StackSafe: Conquering Stack Overflow in Recursive Rust

Recursive functions in Rust are prone to stack overflows, crashing your program. StackSafe solves this by automatically growing the stack in recursive functions and data structures. Simply add the `#[stacksafe]` attribute, and your code works without crashes. Used in production by ScopeDB for petabyte-scale data, StackSafe provides complete protection for both recursive functions and their derived traits (like `Debug`, `Clone`, `Drop`), offering comprehensive stack safety and debug-time checks to catch potential overflows early.

Newton's Infinite Summation: A Story of Discovery

2025-09-21

Newton's Infinite Summation: A Story of Discovery

While studying mathematics, a young Newton ingeniously solved the problem of finding the area of a circle using infinite series through analogy and observation. Instead of directly tackling the circle, he investigated the areas under a series of more general curves. By observing patterns in these areas, he deduced an infinite series representation for the area of a circle. This process was full of guesswork and verification. Newton not only found an approximation for the area but also developed the powerful theory of power series, laying the foundation for the development of calculus. This showcases Newton's extraordinary mathematical intuition and problem-solving skills, and teaches us that changing our perspective on a problem can often lead to greater breakthroughs.

AI-Generated CUDA Kernels Outperform PyTorch?

2025-05-30

Researchers used large language models and a novel branching search strategy to automatically generate pure CUDA-C kernels without relying on libraries like CUTLASS or Triton. Surprisingly, these AI-generated kernels in some cases outperform even expert-optimized production kernels in PyTorch, achieving nearly 2x speedup on Conv2D. The method leverages natural language reasoning about optimization strategies and a branching search to explore multiple hypotheses in parallel, effectively avoiding local optima. While FP16 matrix multiplication and Flash Attention performance still needs improvement, this research opens a new frontier in high-performance kernel autogeneration, hinting at the immense potential of AI in compiler optimization.

CoreWCF Streaming RPC Performance Bottleneck: A Stack Overflow Failure Postmortem

The author attempted to use CoreWCF for streaming RPC between .NET Framework and .NET 8 to test the throughput of random number transfers. However, after posting a question on Stack Overflow, it was closed without an answer. The issue is that the CoreWCF service continues to consume significant CPU and write to the stream even after the client disconnects. The author suspects a misunderstanding of how WCF streams are supposed to work, suggesting WCF streams may not be suitable for handling streams of unknown length. The article explores the challenges of using WCF streaming for high-throughput RPC and considers alternatives, such as using single message requests or session mode, to improve performance and reliability.

Apple Resurrects Blood Oxygen on Apple Watch, Bypassing Import Ban

Apple announced Thursday a redesigned blood oxygen feature for select Watch Series 8, Series 10, and Apple Watch Ultra models, circumventing an International Trade Commission (ITC) import ban. Blood oxygen data is now processed on the paired iPhone, viewable only within the Health app's Respiratory section. This follows a recent U.S. Customs ruling allowing Apple to import watches with the revised feature. The change doesn't affect previously sold models or those purchased outside the U.S., applying only to watches sold after the ITC ban in early 2024. Users can access the redesigned feature via an iPhone and Apple Watch software update released Thursday. This follows Apple's ongoing legal battle with Masimo, which accused Apple of stealing its pulse oximetry technology. Masimo won a 2023 ITC ruling blocking Apple Watch imports with blood oxygen monitoring, prompting Apple's removal of the feature. Apple countersued, claiming Masimo copied Apple Watch features, and appealed the ban.

Bazel Caching, Remote Execution, and glibc Version Mismatch Crash Production

This article details a production crash caused by the interaction between Bazel caching, remote execution, and differing glibc versions across environments. A developer builds and tests a change locally, CI leverages the cache to build a release, but deployment to production fails due to a missing 'GLIBC_2.28' version. The article analyzes how glibc version discrepancies break build reproducibility and presents solutions: a quick hack involves capturing local and remote glibc versions, selecting the higher one for the C++ toolchain; a more robust solution restricts Action Cache writes, forcing builds to run on remote executors; the ultimate solution utilizes sysroots, installing multiple glibc versions across environments and explicitly specifying which to use. The article stresses the importance of reproducible builds, recommending solutions based on context.

AI-Assisted Search-Based Research: Finally Useful!

For two and a half years, the dream of LLMs autonomously conducting search-based research has been pursued. Early 2023 saw attempts from Perplexity and Microsoft Bing, but results were disappointing, plagued by hallucinations. However, the first half of 2025 brought a turning point. Gemini, OpenAI, and Perplexity launched "Deep Research" features, generating lengthy reports with numerous citations, albeit slowly. OpenAI's new o3 and o4-mini models are a breakthrough, seamlessly integrating search into their reasoning process to provide reliable, hallucination-free answers in real-time. This is attributed to robust reasoning models and resilience to web spam. While Google Gemini and Anthropic Claude offer search capabilities, they lag behind OpenAI's offerings. A stunning example: o4-mini successfully upgraded a code snippet to a new Google library, showcasing the potential of AI-assisted search, but also raising concerns about the future of the web's economic model and potential legal ramifications.

Linux Git Commit SHA Prefix Collision Risk Imminent

Linux's "Fixes" tag traditionally uses a 12-character commit SHA prefix, but with increasing commit numbers, the risk of collisions is growing. Security researcher Kees Cook has successfully created a 12-character prefix collision, breaking tools that parse the "Fixes" tag. This collision uses the initial commit ID of Linux 2.6.12-rc2, impacting tools such as linux-next's "Fixes tag checker" and the Linux CNA's commit parser. To prevent future collisions, Cook suggests increasing the minimum short ID to 16 characters and has released a test commit to help developers fix their tools.

Microgravity: A Unique Environment for Space Research

Microgravity isn't the absence of gravity, but rather an extremely weak gravitational field (1/1000th to 1/1,000,000th of Earth's gravity). The International Space Station, contrary to popular belief, isn't in zero-G, but experiences continuous freefall, creating the sensation of weightlessness. In microgravity, fluids, cell growth, combustion, and crystal formation behave differently, offering unique experimental possibilities. Spark Gravity is focused on programmable gravity, bridging the gap in current research limited to either full gravity or zero-G environments on Earth and the ISS. Their goal is to allow scientists to control gravity as a variable, simulate lunar, Martian, or deep space environments, and conduct long-duration studies without the need for a full space station.
