⚙️ Challenging the Fastest Open-Source Workflow Engine
A great technical deep dive showing how Rust and WASM can rival traditional orchestration systems in performance while keeping deployments simple and lean—ideal reading for developers building self-hosted automation tools.
The Obelisk team benchmarked its Rust-based open-source workflow engine against competitors like WindMill, Temporal, and Airflow. The study compared performance across compiled and interpreted languages, native vs. WASM execution, and SQLite optimizations. Obelisk introduced logical transactions and deterministic event caching to boost throughput and reliability. The findings reveal that Obelisk’s minimalist, WASM-first design delivers strong efficiency with a lightweight footprint.

💻 Ask HN: Who’s Running Open LLMs and Coding Assistants Locally?
This community-driven discussion could become a valuable resource for developers experimenting with local AI tools and workflows beyond the cloud ecosystem.
A Hacker News user asks the community about their experience running open-source LLMs and coding assistants locally, such as Ollama or LM Studio. They seek details on model choices, editor integrations like VS Code, and the best-performing hardware setups. The discussion gathers practical knowledge on reliability and efficiency in on-device AI workflows for developers.

🍎 My Impressions of the MacBook Pro M4
A refreshingly honest take from a developer focused on usability and experience rather than specs—a welcome contrast to typical tech hype.
Developer Michael Stapelberg reflects on six months with the MacBook Pro M4, noting its exceptional display, long battery life, and quiet operation. He chose the base M4 model for cooler, fanless performance and found the 120 Hz screen enhanced responsiveness. Though a Linux enthusiast, he praises Apple’s hardware polish and wishes the MacBook Air shared its display quality.

🧩 Just Use a Button
A sharp reminder that clean, semantic markup is still one of the strongest tools for accessibility and maintainability in web development.
Chris Ferdinandi explains why developers should use the native <button> element instead of <div> tags for interactive content. He shows that attempts to retrofit <div> elements with roles, tabindex, and event listeners create accessibility and maintenance problems. His advice is simple but essential: embrace semantic HTML for accessible, reliable interfaces.

🧠 How Sleep Deprivation Disrupts the Brain’s Cleansing Process
This research deepens our understanding of how the brain balances recovery and alertness, showing that tiredness triggers biological cleaning rather than simple mental exhaustion.
MIT scientists found that when people lack sleep, waves of cerebrospinal fluid—normally active only during sleep—begin flowing through the brain while awake. These waves coincide with lapses in attention, suggesting the brain partly enters a sleep-like cleaning mode. The study also observed heart, breathing, and pupil changes, revealing an interconnected system between attention, rest, and physiology.

🔒 Leaker Reveals Which Pixel Phones Are Vulnerable to Cellebrite Hacking
A striking reminder that privacy innovation often comes from open communities, not major vendors—showing how transparency drives stronger security.
A leaker published Cellebrite’s internal chart showing which Google Pixel models can be compromised by law enforcement extraction tools. Pixels running stock Android from versions 6 through 9 remain partially vulnerable, while those on GrapheneOS resist most attacks. The report highlights how independent privacy OS projects can sometimes surpass official Android security.

🧩 Reasoning Models Work—Until They Don’t
An important contribution reminding AI researchers that strong benchmark scores don’t always equate to robust reasoning—highlighting the need for deeper complexity-aware evaluation.
A new arXiv paper investigates how large reasoning models (LRMs), specialized LLMs fine-tuned for problem solving, struggle beyond a certain task complexity. The authors introduce the Deep Reasoning Dataset (DeepRD) to measure these limits and reveal that many LRMs fail to generalize to harder reasoning problems despite strong benchmark results.

🦀 Futurelock: Avoiding Hidden Deadlocks in Rust Async Code
A must-read for Rust engineers—clear, actionable, and reflective of the community’s focus on correctness and reliability in concurrent systems.
Oxide Computer’s RFD describes ‘futurelock,’ a concurrency issue in Rust’s async model where borrowed futures in `tokio::select!` loops can deadlock. It recommends safer designs such as spawning separate tasks and explains the interplay between cancel-safety and blocking behavior. The document offers developers concrete strategies for writing robust, deadlock-free async systems.
