Today's tech landscape is buzzing with AI model comparisons, practical database migrations, and a nostalgic look back at hardware milestones. From a 50-year-old CPU to a 15-year-old netbook, the past is being revived with modern software. Meanwhile, security researchers uncover a six-year-old GPS leak in IoT cameras, and developers debate the merits of SQLite versus traditional databases.

AI & Machine Learning

1. Fable 5 vs. GPT-5.6 Sol on an NP-Hard Problem: Does /goal help? — A detailed benchmark shows Claude Fable 5 outperforming GPT-5.6 Sol on a fiber-network design problem, with the /goal mode providing inconsistent benefits.
2. The Kimi K3 Moment — Kimi K3 matches Claude's coding quality at a fraction of the cost, highlighting the failure of US AI policy to constrain open-source models.
3. Kimi K3, and what we can still learn from the pelican benchmark — Simon Willison tests Kimi K3 with his famous "pelican riding a bicycle" SVG prompt, noting the benchmark's diminishing correlation with model quality.
4. The Isomorphic Labs Drug Design Engine unlocks a new frontier beyond AlphaFold — Isomorphic Labs' new Drug Design Engine more than doubles AlphaFold 3's accuracy on protein-ligand structure prediction, bridging the gap to real-world drug discovery.

Open Source

1. Elixir-lang.org has a new design — The Elixir website gets a fresh look, emphasizing the language's scalability, productivity, and ecosystem from Phoenix to Nerves.
2. Lobste.rs is now running on SQLite — After a year-long effort, the social news site migrated from MariaDB to SQLite, resulting in lower CPU/memory usage and reduced costs.
3. Setting up your spare Mac for Claude Code to control, a step-by-step guide — A practical guide to creating an isolated environment for Claude Code on a spare Mac, enabling remote control via SSH and the Claude app.

Tools & Performance

1. Speech Recognition and TTS in less than 500kb — Moonshine Micro brings voice activity detection, speech-to-text, and neural TTS to microcontrollers like the Raspberry Pi RP2350, using as little as 470 KB of RAM.
2. Static search trees: 40x faster than binary search (2024) — An in-depth exploration of S+ trees that achieve massive throughput improvements over binary search through SIMD, prefetching, and clever memory layouts.
3. Learning a few things about running SQLite — Julia Evans shares practical lessons from using SQLite in production with Django, including the importance of ANALYZE and backup strategies.

Science & Research

1. First atmosphere found on Earth-like planet in habitable zone of distant star — Researchers detect helium in the atmosphere of LHS 1140b, a rocky planet 48 light-years away, marking the first such discovery for a habitable-zone exoplanet.

Hardware & Retro Computing

1. The Zilog Z80 has turned 50 — A nostalgic deep dive into the history and architecture of the Z80 processor, which launched in July 1976 and powered countless home computers and embedded systems.
2. Reviving a 15-year-old netbook with Arch Linux — A detailed walkthrough of installing Arch Linux 32 on an ASUS Eee PC 1000HE, breathing new life into a 2009 netbook with an Intel Atom N280.
3. Show HN: A zoomable timeline of 4M Wikipedia events — A Kotlin Multiplatform app that visualizes 4 million Wikipedia events on a zoomable timeline, scored using PageRank.
4. Show HN: Q3Edit – Edit and play Quake 3 maps in the browser — A browser-based level editor for Quake 3 that supports brush/patch editing, terrain sculpting, and direct map playback via WebAssembly.

Security & Privacy

1. TP-Link Kasa cameras leaked home GPS via unauthenticated UDP for 6 years — A comprehensive security analysis reveals that TP-Link Kasa cameras exposed precise GPS coordinates over unauthenticated UDP, a vulnerability patched only after six years.

Business & Startups

1. If You Build It, They Will Come — A reflection on community building: organizing events is the fastest way to join a social group, and the scarcity of social fabric is due to too many free riders.

Fun & Culture

1. Why do AI company logos look like buttholes? (2025) — A humorous analysis of the circular, central-opening design trend in AI branding, from OpenAI to Anthropic, with a nod to pareidolia.

Other

1. Real-Time LuaTeX: Recompiling Large Documents in 1ms [pdf] — A PDF paper (binary content) on achieving 1ms recompilation for large LuaTeX documents.
2. Regressive JPEGs — A creative hack that packs multiple images into a single progressive JPEG by manipulating scan headers, enabling "video" playback in image viewers.

That's all for today. Whether you're optimizing search trees or reviving vintage hardware, remember that the best tools are often the ones you build yourself.
