Show HN: Skill for your agent to visualize your gbrain and Obsidian

brain-map-skill is a GitHub project that turns a folder of Markdown notes (Obsidian/gbrain) into a self-contained interactive HTML knowledge map. It generates a themed force-directed graph with a scrub-able growth timeline, plus a click-to-inspect panel. The repo ships a prebuilt demo (no setup) and a builder (Python) to render maps from notes with YAML frontmatter and wikilinks. It runs client-side; no server required, but prints layout with optional pre-computed maps for speed. The demo vault contains ~992 fictional notes across Work/Study/Life. It can be installed as an agent skill for Claude/Code, etc.

Automating Myself Out of Development

An informal diary of offloading development to Claude Code through a daemon-driven workflow. The author moves from local brainstorming to EC2, then to GitHub as a planning board, and finally to a cron-based daemon that runs, reports, and updates state. Phases cover isolating projects, stand-alone operation, backlog-driven planning, enrichment of context, and optional auto-brainstorming, all gated by labels. The current flow has five human touchpoints; failures go to need-attention. The piece weighs productivity against security and debt, questions how far to delegate thinking, and argues there’s no single best AI-use recipe yet.

Leaving Mozilla

After 15+ years at Mozilla, jr conlin announces he’ll leave on July 21. In a candid farewell, he urges focusing on people over corporate metrics, mentoring, and the real community that supports Firefox. He argues Mozilla’s strength lies in being a niche, open-source browser built for users who seek something different, not in copying big browsers or chasing enterprise dollars. Leadership’s “start-up” mindset and DAU obsession have sidelined the community and core product. He advocates restoring community involvement, reviving legacy projects (Thunderbird, Rust, Servo), fixing bugs, and keeping Firefox private, useful, and opt-in.

Shepherd's Dog: A Game by the Most Dangerous AI Model

Koen van Gilst tests Anthropic’s “dangerous” AI by asking it to build a game idea in one shot. After a long reasoning session, ~45 minutes and €20 in tokens, the model outputs Shepherd’s Dog as a complete 2,319-line index.html with no dependencies. The author says it’s fun, exactly as envisioned, and a first for one-shot AI game creation, noting earlier attempts with a GitHub link and sharing video or access to the game.

Show HN: Lightweight Task queue on Erlang/OTP, SQLite-backed, no overengineering

EZRA is a single-node, persistent task queue backed by SQLite, exposing a Redis-like protocol and Redis Streams API (XADD, XREADGROUP, XACK, XDEL, XNACK). Producers push tasks to named queues; workers pop and ack tasks over TCP. All data lives in ezra.db with no broker or cluster. It offers at-least-once delivery, automatic replays on crash or timeout, and configurable retention, via a self-contained binary (~20 MB). Suitable for background jobs on one machine with polyglot clients; not designed for multi-node, fanout, or scheduling; throughput depends on disk.

There is a shadow hanging over this Fable thing

An AI writer explains that a US export-control directive forced Anthropic to disable Fable 5 and Mythos 5 for all users, including foreign nationals and employees. He recounts failed attempts to regain access, analyzes the political context of AI regulation, and questions whether such restrictions will curb innovation or harm AI infrastructure. He notes other Anthropic models remain available, compares to past safety disclosures (GPT-2), and warns this could set a dangerous precedent for access to powerful LLMs.

A generic dynamic array in C that stores no capacity and needs no struct

Describes a generic dynamic array in C that stores no separate capacity and needs no struct. Implemented as an array of two pointers (e.g., int *vec[2] = {0}); vec[0] holds the length (uintptr_t) and vec[1] points to the data. A vec_push macro appends values and, when length is zero or a power of two, reallocs to the next power-of-two capacity. No explicit capacity storage; shrinking is manual. Demonstrates with ints and a struct, using GNU C features.

Anthropic's leaning in to the whole nanny state thing

Kirk Strauser's Honeypot.net piece argues that Anthropic is adopting a nanny-state approach to AI regulation. It frames the stance as a critique and cites a real screenshot as evidence, published June 12, 2026.

TycoonLE: A Jax reinforcement learning environment for long-horizon planning

TycoonLE is a JAX-based reinforcement learning environment simulating a logistics economy where agents manage capital, build routes, move cargo, debt, and rewards; designed for long-horizon planning, action legality, financing timing, and replayable audits; uses a fixed-shape interface with actions: route, finance, or wait; compatible with JAX transforms; includes TycoonBench benchmark; install with Python 3.11/3.12; provides quickstart, PPO training examples.

Our response to the US ban on Fable 5 and Mythos 5

The US issued an export-control directive banning access to Anthropic’s Fable 5 and Mythos 5 for foreign nationals, forcing their global removal. It’s the first such LLM export control and could affect any app relying on US-based models. Isaacus, an Australian AI firm, will keep all models self-hostable and air-gapped, doubling down on AI sovereignty to keep frontier intelligence accessible and disrupt monopolies. They caution about dependence on external LLMs (Anthropic’s Stainless, acquired and wound down) and plan self-hostable futures (Blackstone Graph, Isaacus Research).

Why a Computer Science Degree Still Opens Hidden Doors

The article argues that the computer science degree isn’t dead, but the job pipeline is misaligned. While unemployment/underemployment figures can look worrying, CS and computer engineering still offer strong outcomes when contextualized. The bigger problem is hiring: entry‑level postings surged while actual hires fell and ghost jobs mask opportunities. The path forward: network for warm referrals, pursue real‑world experience (deployed projects, open source), and develop durable AI engineering skills (not just tool fluency), including building RAG pipelines and production apps. Startups can be valuable stepping stones; long‑term skills matter more than initial conditions.

Open Source AI Must Win

Opensource AI Must Win argues that AI should remain open and locally deployable so people can study, build, repair, deploy, audit, teach, preserve, and run intelligence systems without permission. AI is civilizational infrastructure for work, education, science, software, creativity, public services, and national capacity; access must not depend on closed APIs, remote platforms, opaque moderation, model availability, or price gouging by a few companies. Open-source AI should be usable, understandable, reproducible, economically viable, and community-governed, even if dominant labs or platforms shift. It calls for American capacity aligned with global open standards to prevent a cognition subscription economy.

A key remapping daemon for Linux

keyd is a Linux system-wide key remapping daemon that operates at the kernel input level (evdev/uinput). It provides layers, oneshot modifiers, key overloading (tap/hold), per-keyboard configuration, and supports X, Wayland (sway), and virtual terminals. It uses a client-server model controlled by a config file, aiming for fast, simple, consistent remapping without flashing firmware. Installation: clone, make, sudo make install, enable the keyd service. Config examples show capslock/escape handling and app-specific mappings. It notes libinput quirks for trackpads and is MIT-licensed.
