Leo’s Moon Ship suffered a drift when switching animations: a single global scale/offset made different canvases yield inconsistent character heights, so Leo’s feet appeared off the ground. The fix: compute per-animation metrics at load. For each frame, detect the visual feet line by scanning the alpha bbox from the bottom, average across frames, and pick a reference (idle_right). Then set anim_scale and anim_offset_y per animation so every animation renders to the same height and feet align to ground; apply on animation changes. The shadow pins to the feet too. Result: stable, correct alignment.

Alibaba's Qwen3.7-Max autonomously ran a kernel optimization task on unfamiliar ZW-M890 PPUs for 35 hours, making 1,158 tool calls and continually writing, compiling, profiling, and redesigning the kernel to achieve ~10x speedup over the reference. It outpaced GLM 5.1 (7.3x), Kimi K2.6 (5x), and DeepSeek V4 Pro (3.3x). The effort illustrates 'environment scaling'—training across diverse tasks/tools to boost generalization beyond benchmarks. Limitations: proprietary API with no open weights or self-hosting; self-reported results; not readily deployable.

Vadim Drobinin mined 20 years of chats (1.2M messages) to build a structured vault of his life, turning messy data into a personal CRM. He pulled archives from ICQ/IRC/DC++ through VK, Twitter, Facebook, Telegram, and Instagram, then cleaned noise (roughly 41%) and resolved who’s who across platforms. An LLM-based pipeline produced daily notes, events, sentiment, and profiles, while a deterministic script ingested JSON into an provenance-tracked SQLite store. Findings show relationships evolve in bandwidth and vocabulary: ~13% of conversations are transactional, with changing endearment and response dynamics. Not a bad friend after all; memories and birthdays tracked.

Three problems block image pasting from Windows to Claude Code in WSL inside Windows Terminal: (1) WSLg only syncs images to Linux as BMP (BI_BITFIELDS), unreadable by Claude Code; (2) even when you convert to PNG, WSLg overwrites the Linux clipboard with BMP shortly after; (3) Windows Terminal eats Ctrl+V before Claude Code can receive it. The fix is a three-part bridge: clip-listener.exe converts Windows images to PNG; wsl-clip-bridge pushes the PNG to the Linux clipboard and re-asserts after overwrite; Alt+V bound to Claude Code’s image paste to bypass Terminal. Install from the repo and enable the Alt+V binding.

Argues that AI could dramatically boost productivity across white-collar work, potentially letting people finish a week's output by midday Monday. The author proposes taking Friday off, with Monday–Thursday work and AI agents handling Friday tasks—an “AI workers’ day” for all leadership. The idea explores practical and social implications of a four‑day or flexible week in a world transformed by AI, including a cheeky aside to Elon about childcare costs and fertility.

Update dependencies cautiously; the industry’s rush to “latest” and Dependabot has amplified supply-chain risk. Open-source growth left maintainers overworked and traditional tooling inadequate for preventing sophisticated compromises. Humans alone cannot secure the modern supply chain; dependencies are untrusted contributions. The article proposes Mendral’s CI‑integrated AI review, which on every PR analyzes dependencies with sandbox tests, provenance scoring, and context-aware remediation, surfacing risks and suggesting fixes. It advocates moving beyond blind updates and toward proactive, thorough dependency management, offering early access to their platform.

The author argues for mesh networking to reduce dependence on centralized ISPs and censorship. He reviews Meshtastic (early, easy for small groups, but not scalable) and MeshCore (better routing, but largely proprietary and restricted). He champions Reticulum as the future, a routing stack that can use LoRa, LAN, Wi‑Fi, the Internet, etc., to create large, interconnected, decentralized networks with strongly encrypted routing and a global address space. The main drawback is lack of standalone LoRa firmware; progress on microReticulum for ESP32 may fix this. He plans to build with Reticulum.

After Pandoc and Typst updates broke my earlier Pandoc+Typst workflow, I rebuilt it around Pandoc’s Typst output template and a Typst-specific template (article.typ). Use: pandoc file.md -o file.pdf -V template=article.typ --pdf-engine=typst. The template imports the Typst template when that variable is set, separating Pandoc and Typst logic. It collects Pandoc metadata, sets defaults (page, font, numbering), and provides configurable headers/footers, typography options, and styling for quotes, code, images, captions, footnotes. It also defines heading levels, epigraphs, references, and inline styles; layout starts with a title block, justified body, then a colophon.

Elodin has open-sourced a practice rig for Anduril's AI Grand Prix to let teams start writing autopilot code before the official Virtual Qualifier 1 simulator drops. The stack fuses a Rust ECS physics core (nox) with Python bindings, a 3D editor tied to a time-series telemetry DB, and a small runner (s10), all synced with Betaflight SITL via a UDP bridge at 1 kHz. Contestants implement solver(update: SensorUpdate) -> RCCommand; a simple altitude/position PID serves as baseline. Apache-2.0, macOS/Linux; install via scripts; welcomes PRs and feedback. Caveats include ENU vs NED, drag-only atmosphere, and camera FOV quirks.

Pelica Health, a YC-backed startup building an AI-driven operating system for value-based care, is hiring a Contract Machine Learning Engineer (SF/remote) for $80K–$150K. You’ll own production ML systems end-to-end: data modeling and feature engineering, data pipelines from healthcare data, training/evaluation, deployment and monitoring, and integration with backend services. Requirements include 3+ years of production ML experience, strong tabular-data ML, data pipelines, backend coding, and solid system design; ability to explain modeling choices; comfort in a fast-moving startup. Bonus: healthcare/operational decision-support experience, LLM in production, startup mindset.

Technical note detailing the Geiger-Muller tube mounting dimensions on the GGreg20_V3 PCB to help buyers use a tube from elsewhere. Although originally designed for SBM20, the module now uses J305; Chinese-market size variations mean some J305 tubes differ in length. The post provides current J305 data from the supplier, a technical drawing, and photos showing typical size variation. It notes only a few defective or outlier tubes in years of testing. The aim is to help users choose a tube that fits the module, especially in length, while SBM20 also fits.
