  Visualizing Algorithms for Rate LimitingThis post explores the importance and implementation of rate limiting to manage traffic and prevent abuse, such as spam or brute force attacks. It details three common algorithms: fixed windows, sliding windows, and token buckets. Fixed windows are simple and predictable but can allow bursts. Sliding windows smooth traffic but are resource-intensive. Token buckets support high-traffic bursts while maintaining a long-term average rate. The post also covers practical considerations for implementation, such as persistent storage and handling errors, and includes visualizations and real-world examples like GitHub and OpenAI.Read more

• HigherOrderCO/Bend

  Bend is a high-level, massively parallel programming language offering Python and Haskell-like features, yet optimized for GPUs. It boasts near-linear speedup based on core count without explicit parallel annotations. Setup requires Rust, with options for C and CUDA runtimes. Bend simplifies parallel programming; complex algorithms exhibit significant speedups without manual parallelization efforts. Long-distance communication is facilitated efficiently. While Bend's single-core performance lags, ongoing development promises substantial improvements. Despite its infancy, Bend offers a glimpse into high-level, massively parallel programming.
