tl;dr: Veteran tech journalist and venture capitalist Om Malik, founder of GigaOm and partner at True Ventures, has died. Known for his influential coverage of Silicon Valley from the early 2000s onward, his writing on broadband, Web 2.0, and the tech industry, as well as his photography and personal essays, Malik was widely respected for his insight, integrity, and generosity to founders and fellow journalists. The post has drawn tributes from a wide swath of the tech and journalism community.

tl;dr: Researchers have virtually unwrapped and read PHerc. 1667, a carbonized Herculaneum scroll, end-to-end for the first time, using high-resolution X-ray microtomography at ESRF's BM18 beamline combined with machine learning to detect ink. The recovered text—roughly 22 columns of Greek—appears to be a 2nd-century BC Stoic treatise on ethics referencing Aristocreon, disciple of Chrysippus. The team also confirmed prior readings of Scroll 1 via direct 3D ink detection and identified another scroll as Philodemus's *On Gods, Book 8*; all data, code, and transcriptions are openly released.

tl;dr: Australia's under-16 social media ban, which is largely failing to keep kids offline, has forced platforms to mandate biometric or government ID verification through third-party services—already resulting in a Discord breach exposing 70,000 users' IDs. The UK, EU, and others are pursuing similar "Australia-plus" laws, with UK officials even floating restrictions on VPNs. In the US, 19+ states and federal proposals like KOSA are heading the same direction, building a surveillance infrastructure that ties online speech to identity verification and creates serious risks for privacy, anonymity, and free expression.

tl;dr: A browser-based game (also available as a desktop app via Python) that puts you in the role of an OS, requiring you to juggle process scheduling, memory allocation, and I/O events before impatient users reboot you. Built in Python with a web version and sandbox/automation modes for development, it's open source under GPLv3. Playable at https://plbrault.github.io/youre-the-os or on itch.io.

tl;dr: IBM unveiled a 0.7 nm ("7 angstrom") chip using a new "nanostack" 3D architecture that vertically stacks and staggers nanosheet transistors, fitting ~100 billion transistors on a fingernail-sized die. The company claims up to 50% better performance or 70% better energy efficiency over its 2 nm node, plus 40% SRAM scaling, with production possibly within five years. Work continues at IBM's Albany facility alongside ASML High-NA EUV and partners like Lam, TEL, and SCREEN.

tl;dr: OpenKnowledge is a local-first, GPL-3.0 markdown editor and LLM wiki positioned as an open-source alternative to Obsidian and Notion, with WYSIWYG editing and built-in integrations for Claude, Codex, and Cursor via MCP/CLI. It ships as a macOS app or a CLI-launched web app for Linux/Windows/Intel Mac, and uses git/GitHub under the hood for team sharing and sync.

tl;dr: OS9Map is a native OpenStreetMap browser for Mac OS 9 on PowerPC, supporting smooth pan/zoom, Nominatim-based address search, and bookmarks. It requires 16MB RAM and an Open Transport TCP/IP connection. Version 1.0.0 marks the first public release.

tl;dr: Zig's `@bitCast` has been redefined with new semantics based on a type's "logical bit layout" rather than reinterpreting memory bytes, making behavior endian-agnostic and enabling operations like converting `[2]u3` to `@Vector(3, u2)`. The change was driven by LLVM backend improvements that now extend arbitrary bit-width integers (u4, u13, etc.) to ABI-sized types in memory—matching Clang's `_BitInt(N)` lowering—which restored missed optimizations and yielded ~5% performance gains in the Zig compiler itself. The new semantics are implemented across all backends and comptime execution, landing in 0.17.0.

tl;dr: A developer building a virtual running app (In the Long Run) built a pipeline using GeoNames, Wikipedia, DuckDB, and Parquet to surface points of interest along routes, with Claude Haiku providing subjective relevance ratings. Hallucinations forced him to abandon LLM-generated summaries in favor of Wikipedia text, relegating AI to a scoring role alongside traditional signals like Wikipedia language counts. The hardest part was evaluation: there's no ground truth or unit test for "taste," and each route needed custom tuning to balance natural, historical, and populated landmarks.

tl;dr: Hacker Trends is a Google Trends–style tool that charts how often topics, tools, or people appear across 18 years of Hacker News posts and comments, built on a date-histogram over 45M items using Upstash Redis Search. Users can overlay multiple terms to compare traction over time and drill down into the underlying stories and comments. The site includes curated comparisons illustrating shifts like Webpack→Vite, MySQL→Postgres, TensorFlow→PyTorch→JAX, and Cursor→Claude Code→Codex.

tl;dr: LastPass is notifying users of a breach involving third-party market research firm Klue, which exposed customer contact info and support case data (but not password vaults). The attackers accessed data via Klue's integrations with Salesforce and Gong; LastPass has revoked access, rotated API tokens, and warned users to watch for phishing. This marks the latest in a string of security incidents for LastPass, following major breaches in 2015 and 2022.

tl;dr: OpenAI announced its first custom inference chip, codenamed Jalapeño, developed with Broadcom and reportedly designed with help from OpenAI's own AI models. The chip targets inference workloads (not training) and claims significantly better performance-per-watt than current alternatives, aimed at reducing reliance on Nvidia GPUs and cutting operating costs for running models like Codex. It follows similar custom-silicon moves by Google and Amazon, and is still in testing.

tl;dr: Cloudflare has opened self-managed OAuth to all customers, letting developers create their own OAuth applications for delegated API access instead of relying on API tokens. To support this, they upgraded their underlying Hydra OAuth engine through a staged 1.X then 2.X migration, using a blue-green strategy with a Cloudflare Queues-based revocation replay system to avoid downtime. The upgrade yielded notable performance gains, including a 45% drop in P95 API latency and 37% lower CPU usage.
