Real engineering failures instead of success stories

FailHub issue #1 covers three failures and lessons: - Silent scope growth: minor changes accumulate; enforce clear boundaries and open dialogue to adjust scope, priorities, or quality. - Everyone agrees, but no one aligns: Definition of Done must be explicit and measurable; show frequent demos; break work into small pieces for early feedback. - Architecture without context: moving logic without project context increases complexity; decisions must consider age, dependencies, team, pace, and goals; prefer stable solutions over theoretically clean ones.

Anciente map of Fairyland. Places from nursery rhymes, fairy tales etc.

An anciente mappe of Fairyland is a 1917 decorative map by Bernard Sleigh depicting Fairyland from nursery rhymes, fairy tales, Arthurian legends, and folktales. Sleigh sketched it to entertain his children; after his 1937 retirement, it became a Rosebank Fabrics print that inspired other fairy-tale patterns. The piece measures about 39 x 147 cm (sheet 46 x 152 cm) and includes a 16-page guide. It is in the Norman B. Leventhal Map & Education Center Collection at the Boston Public Library, with no known copyright restrictions, and has been exhibited in 2015–2017.

Show HN: Zuckerman – minimalist personal AI agent that self-edits its own code

Zuckerman is a minimalist personal AI that starts small, self-edits its own configuration, tools, prompts, and even core logic in plain-text files, and hot-reloads changes in real time. It evolves by sharing useful edits and capabilities with other agents on a shared contribution site, enabling collaborative growth of a living ecosystem of personal AIs. It uses a three-layer architecture (World, Agents, Interfaces), supports multi-channel communication (CLI and Electron UI), built-in security foundations, and tool integration for real-time expansion.

FOSDEM 2026 – Open-Source Conference in Brussels – Day#1 Recap

FOSDEM 2026 centered on Open Source, Digital Sovereignty, and Europe’s future, highlighting self-hosted solutions and community-driven software (FreeBSD, DN42, SmolBSD, BoxyBSD). Talks covered memory-safe virtualization (Rust-VMM), reliable object storage (Garage S3 Best Practices), VM mobility in Kubernetes, minimalist BSD systems, and decentralized networking (DN42). Notable moments included Mozilla’s free cookies and Collabora Online discussions. The event showed growing crowding and political focus, calling for sustainability and accessibility while preserving openness and in-person community.

Amiga Unix (Amix)

Amiga UNIX (Amix) was Commodore’s 1990 port of AT&T System V Release 4 Unix to the Amiga. It officially ran on the Amiga 2500UX/3000UX (and similar Amigas) and can be run in WinUAE emulation since 2013. The wiki preserves Amix history, installation guides (real hardware or emulation), networking, tutorials, software, patches, and community resources. It notes Amix is historical and difficult to install, with a closed-source kernel/libc and no active development, making it mainly of interest for curiosity and learning rather than practical use.

How to Scale a System from 0 to 10M+ Users

Seven-stage guide to scale from 0 to 10M+ users: 1) single server for 0–100; 2) separate database; 3) load-balanced multi‑servers; 4) cache, read replicas, CDN; 5) auto-scaling and stateless with JWTs; 6) sharding, microservices, and queues; 7) multi-region with CQRS and edge computing. Key principles: start simple, measure bottlenecks, keep apps stateless, cache aggressively, use async, shard only when needed, balance consistency and availability, accept complexity costs.

Reliable 25 Gigabit Ethernet via Thunderbolt

An owner’s review of a Thunderbolt-to-25 GbE adapter (PX) that’s powered from the host. It uses a Mellanox ConnectX-4 Lx EN OCP 2.0 NIC with a TB3/4 adapter, offered as single- or dual-port (from about $157). On macOS it’s plug‑and‑play but runs extremely hot, occasionally causing network drops or kernel panics. Throughput is ~20.7 Gb/s one‑way and ~25.4 Gb/s bidirectional, near Thunderbolt PCIe limits; dual ports mainly aid redundancy. Cooling with large heatsinks improves reliability but the unit still needs active cooling. Firmware updates require Linux; the heatsinks prevent the case from closing.

'Unsubscribe' and 'opt out': A new Big Tech boycott to protest ICE

Scott Galloway proposes a targeted Big Tech/AI boycott to protest ICE, starting February. Instead of a general shutdown, Americans would unsubscribe from major services—OpenAI's ChatGPT, Amazon Prime Video, Microsoft Office—for the month, aiming to dent valuations and pressure the White House. The plan follows January protests that strained small businesses during a nationwide strike; many small shops stayed open. Galloway argues a one-month slowdown could be more disruptive than a day of protest and could influence policymaking.

What I learned building an opinionated and minimal coding agent

Zezner describes building a minimal, opinionated coding agent ecosystem (pi) consisting of pi-ai (unified LLM API), pi-agent-core (agent loop), pi-tui (retained-mode terminal UI with differential rendering), and pi-coding-agent (CLI wiring). He argues context engineering is key; compares to Claude Code and others; emphasizes cross-provider context handoff, streaming tool calls, and a type-safe model registry. Tools: read/write/edit/bash with no built-in to-dos, plan mode, or MCP; YOLO default; no background bash; sub-agents discouraged. pi-tui uses two UI styles and synchronized rendering to minimize flicker. Benchmarks and philosophy emphasize observability, control, and extensibility, with openness to fork.
