Welcome to my blog! I write about Rust & modern web development.https://luiscardoso.dev/en-ushttps://luiscardoso.dev/blog/auto-vectorization/https://luiscardoso.dev/blog/auto-vectorization/Compile two Rust loops, inspect the generated asm/LLVM IR, and learn why one vectorizes and the other doesn't.Sat, 25 Mar 2023 00:00:00 GMThttps://luiscardoso.dev/blog/deepsek-r1/https://luiscardoso.dev/blog/deepsek-r1/DeepSeek-R1-Zero explores pure RL on verifiable tasks, while DeepSeek-R1 adds cold-start data, multi-stage RL, and distillation. This post breaks down GRPO, the training pipeline, and what transfers to smaller models.Sat, 08 Feb 2025 00:00:00 GMThttps://luiscardoso.dev/blog/mixture-of-experts/https://luiscardoso.dev/blog/mixture-of-experts/A practical overview of Mixture-of-Experts (MoE): routing, trade-offs, and why models like Mixtral use it.Sun, 10 Dec 2023 00:00:00 GMThttps://luiscardoso.dev/blog/neuralese/https://luiscardoso.dev/blog/neuralese/Reasoning through discrete language tokens can be a bottleneck. This post introduces continuous latent reasoning, where models 'think' directly in high-dimensional vector spaces, and covers architectures, training methods, and limitations like interpretability and evaluation.Fri, 13 Jun 2025 00:00:00 GMThttps://luiscardoso.dev/blog/parsing-data-with-rust-typescript/https://luiscardoso.dev/blog/parsing-data-with-rust-typescript/Parse at the boundary using Rust newtypes and Zod schemas so invalid input never reaches business logic.Sat, 11 Feb 2023 00:00:00 GMThttps://luiscardoso.dev/blog/rust-difference-str-string/https://luiscardoso.dev/blog/rust-difference-str-string/When to use &str vs String in Rust: borrowing, ownership, and allocations.Sun, 05 Feb 2023 00:00:00 GMThttps://luiscardoso.dev/blog/sandboxes-for-ai/https://luiscardoso.dev/blog/sandboxes-for-ai/A practical guide to sandboxing for AI agents and RL environments: containers vs gVisor vs microVMs vs Wasm/isolates, what each boundary actually buys you, and where they fail.Mon, 05 Jan 2026 00:00:00 GMT
