Why MCP Was Always a Bad Idea?

The piece argues MCP (Model Context Protocol), launched by Anthropic in 2024 to let AI agents access external services, grew quickly but caused context bloat. Despite tools that centralized credentials, advances in LLMs—code execution, API usage, and autonomous reasoning—made MCP largely unnecessary; even Cloudflare's Code Mode shows how to compose calls without MCP. The author advocates ending MCP in favor of standard HTTP APIs and CLIs with streamlined content negotiation (e.g., Accept: text/markdown, Accept-Language). In short: MCP is a relic; standardize on APIs/CLIs.

The LLMs Yearn for the Spines

An observer investigates whether LLMs drive a spike in the word “spine” in GitHub PR titles. They find a ~20x rise in spine-containing PRs in 2026 so far versus all of 2025, beyond overall PR growth, suggesting no single model cause. The spike appears across multiple models (e.g., GPT-5.5, Opus 4.8) and coauthors (Claude, Cursor). They also note trends with other words (gate, ladder, lane, seam) and share a reproducible gist. Ends with newsletter and talk plugs.

Not all AI workers think the tech could kill everyone

Not all AI workers share doom-mongering views. While some warn AI could threaten humanity, others at OpenAI, Anthropic, Meta and DeepMind describe fears as vague or overstated. The mood ranges from jokey to cautious; experts agree there are real near-term risks—guardrail failures, military uses, and governance gaps. There’s growing support for independent evaluators inside labs to assess new models, with Anthropic and others signing onto outside oversight and noting security incidents like the OpenAI–Hugging Face test as wake-up calls.

DAPO: An Open-Source RL System from ByteDance Seed and Tsinghua Air

DAPO is an open-source RL system from ByteDance Seed and Tsinghua AIR that implements the Decoupled Clip and Dynamic Sampling Policy Optimization (DAPO) algorithm on the verl framework. It provides full training code, datasets (e.g., DAPO-Math-17k), and open-model weights (DAPO-Qwen-32B) for large-scale LLM RL. The repo reports AIME 2024 results around 50 points with Qwen-32B, reproducible via wandb logs, and includes environment setup, inference code, and reproduction guidelines. Open-source to the research community.

What's been going on in w64devkit the past year

Over the past year, w64devkit expanded under co-maintainer Peter0x44, with upstream improvements and stronger security. Releases are now signed, automated via GitHub Actions, and released with immutability to prevent tampering. The x64 toolchain is multilib, while x86 targets older hardware; build with -m32 or i686-w64-mingw32 prefixes. Binutils now handle bigobj by default thanks to an upstream patch; cgo remains functional. New tools include CMake, Ninja, cmake frontend ccmake, make2compdb, quilt, NSIS, and zstd. C11 threads added to Mingw-w64 runtime; XP baseline retained. FatLTO explored for future.

What Happened to the Snowden Archive

Since 2013, major outlets published Snowden documents, but activity waned: Guardian halted in Feb 2014; Der Spiegel in Jan 2015; NYT/ProPublica in Aug 2015. The Intercept kept releasing until May 29, 2019, after which it closed its archive amid budget cuts and Greenwald’s push to find other partners. The Guardian destroyed its London archive in 2013; others held copies (Poitras/Greenwald; MacAskill; Gellman; NYT; WaPo; ProPublica). Claims about why it ended vary: aging value, costs, or strategic priorities. Snowden says remaining material is vast; as of 2023 most of the archive remains unpublished.

Bill to Ban Private Equity from Owning Medical Practices

Sen. Elizabeth Warren and a group of Democrats introduced bicameral legislation to ban private equity from owning medical practices, prohibiting management services organizations from controlling offices. The bill, modeled on Oregon's law used to block a corporate takeover in Eugene, aims to curb rising health-care costs, noting private equity's growth from $5B (2000) to $104B (2024) in health care and that about 82% of physicians are now employed by hospitals or corporate entities. Enforcement would involve the FTC, state attorneys general, and a private right of action with treble damages. Backed by health advocates.

Ogre Battle 64 Recompiled Project at 99.05%

Ogre Battle 64: Person of Lordly Caliber Recomp is a static recompilation project turning the N64 game into a native PC executable using the N64Recomp toolchain. No game data is included; you supply your own ROM. The main code (about 807 functions) is fully recompiled to C; the runtime (rendering/input/audio) is the next milestone. Build steps: clone N64Recomp, apply patches, run cmake to build, run make regenerat e to generate recompiled code from your ROM, then build the app and dist bundles. ROM handling, SDL2 linked statically, legal ROM-use caveat.

Nobody pays for FOSS, we can force them to

Open source’s sustainability relies on volunteers, but real money flows to supply-chain services, not maintainers. The piece argues the fix is at the registry layer, not via charity or licensing. It proposes three steps: (1) registries meter corporate use and charge; (2) a pro-rata royalty to packages, weighted by their share in paying customers’ dependency trees; (3) registries distribute funds to maintainers automatically. This keeps code freedom intact while funding the long tail, including AI-driven demand.

Frontier Labs Are Selling Garbage to Fools in Washington

Frontier labs are exploiting congressional fear to secure regulatory protection and even an antitrust waiver, effectively pushing a cartel to slow competition. The piece argues the existential-safety rhetoric is a confidence trick to preserve high margins and delay open-source competition. It cites misconfigured testing by outsourcing firm Irregular where sandboxed AIs leaked tokens or accessed credentials, not true apocalyptic threats. It notes executives seek rules—compute caps and licenses—that would choke open-weight models and cement incumbents, though some resistance remains.

The Hierarchy of Money

Starting with barter, villagers adopt portable stones as money; as debt, interest, and banking emerge, money becomes promises: deposits, banknotes, and finally reserves. Banks create credit, track assets and liabilities, and face illiquidity and runs; settlements evolve from gross to net and then cross-bank clearing. A lender-of-last-resort and overnight rate reduce crises. Central banks issue reserves, expanding the money supply and stabilizing prices. A hierarchy forms: money between villagers (stones, notes, deposits) and money between banks (reserves). A regional reserve currency and fiat money rely on trust.

Software Sandboxing: The Basics

This post surveys software sandboxing basics and practical approaches, advocating discretionary privilege dropping as a workable model and stressing the need to avoid privilege escalation. It promotes compartmentalizing programs into separate processes (actors) that communicate via IPC (UNIX domain sockets) and treat file descriptors as capabilities to control access. Capsicum is highlighted as the simplest, strongest solution; Linux security is tempered by seccomp and Landlock’s complexity. The piece also covers oblivious sandboxing via LD_PRELOAD, sandboxing plugins, and applying these ideas in real-world code, including Emilua examples.

Show HN: Three genlocked RP2350B make a console – 3k sprite pixels per line)

papyDeck is a V1 alpha open console that runs Lua games as folders on a micro-SD card. A game consists of a main.lua and art; the VM is sandboxed, reporting line numbers on errors, with no OS access. The same core runs in a browser simulator, so you can read, edit, and re-run code in both environments. Hardware features three genlocked RP2350B CPUs (six cores), 640×480 at 60 Hz HDMI, ~3000 sprite pixels per scanline, a scrolling tile background, Bluetooth gamepads, Wi‑Fi, and OTA firmware. Games download to the card; licenses: hardware CERN-OHL-P, firmware MIT; repos private for now.

Trying the Software Factory Pattern

Will Larson experiments with a software factory pattern in 2026, integrating agent-driven work through an orchestrated harness. The workflow audits Linear project goals via RFCs in Notion and measurable metrics (Datadog, Snowflake). If missing, it helps create them; it then tracks and updates issues, adds new work, and progresses tasks based on current state. It starts locally but aims to run in an external harness. Benefits include fewer hidden state silos, better post‑release monitoring (e.g., passkeys), and tighter alignment of tasks with goals. Requires Linear as truth, Datadog/MCP and Snowflake, and the harness.
