CMS uses a new machine-learning algorithm to reconstruct LHC particle collisions faster and more precisely than traditional methods, improving data analysis.
Timsort is a fast hybrid sorting algorithm that combines merge sort and insertion sort. It divides data into runs, sorts them with insertion sort, then merges them efficiently. It's optimized for real-world data, often running in linear time on partially sorted inputs.
The article explores moving from identity-based to capability-based authority in distributed agentic systems, using Biscuit tokens as a self-contained example. The author built a minimal Clojure implementation, Kex, to understand the model's trade-offs like delegation complexity and revocation.
MySQL and PostgreSQL implement ACID differently. MySQL uses clustered indexes where table data is stored in the primary index, while PostgreSQL uses heap tables with separate indexes. In performance tests, PostgreSQL consistently outperformed MySQL across inserts, updates, deletes, and selects, despite theoretical advantages for MySQL in certain scenarios.
GoFigr captures plots in Python via Jupyter's single display system, making auto-publish reliable. In R, the graphics architecture lacks a central point, so auto-publish is experimental. Explicitly piping plots to publish() is recommended for R users as it's more reliable and idiomatic.
-fbounds-safety is a proposed C extension using annotations to attach bounds to pointers, turning out-of-bounds memory accesses into deterministic traps to prevent security vulnerabilities.
Modern compilers use a query-based model instead of a linear pipeline, enabling incremental reuse and faster IDE responses by caching results and minimizing work.
A programmer's journey from Pascal to C, then web dev in PHP/Python, and finally Rust for a web app. Despite loving Rust's control and safety, they switched to Node.js due to faster iteration, better web ecosystem, and type-safe templates, concluding Rust excels in CPU-heavy tasks but Node.js is more practical for dynamic web development.
A developer built Context Lens to trace LLM context usage. Testing four AI coding tools on the same bug fix revealed vastly different token consumption and strategies: Claude Opus was surgical (23K tokens), Codex efficient (29-47K), Claude Sonnet balanced (42-44K), and Gemini profligate (up to 350K tokens). The tools show no deliberate context management; efficiency stems from investigation strategy, not optimization.
Apache Poison Fountain is a tool to poison AI training data by serving subtly incorrect content. Hacker News comments discuss its risks, like enabling attacks and benefiting large AI firms over smaller ones.
UK proposes law requiring tech firms to remove non-consensual intimate images within 48 hours, with fines up to 10% of global revenue for non-compliance.
