Hi HN, today I’m revealing Altar II, an ultra-low profile (4.75mm) mechanical keyboard designed to replace your Magic Keyboard. It’s the keyboard I wish Apple made. Altar II has fully mechanical switches, plus a magnetically detachable dial, haptic feedback, a red backlight, and a native macOS companion app. I’m a heavy Mac user and I feel that Apple hasn’t given its keyboards the attention they deserve, in terms of hardware, software, and features, so I set out to try and change that.

Line9 is a new rendering engine for Mermaid flowchart diagrams that aims to remove the need for manual adjustment of layout. Mermaid is a popular text-based language for describing multiple types of diagrams. Several Mermaid rendering engines already exist. Most, like the original mermaid.js, use Dagre or ELK graph drawing libraries to automatically lay out their diagrams.

Instead of a real estate tycoon, you are an elected steward of the building, held responsible by the Assembly. Homes are allocated off a waitlist, dues are set on a sliding scale, and you face outside pressures from neighboring capitalist landlords. The crown jewel

This started life as a graphics tool for a specific problem: gen AI can make retro-styled sprites but can't follow exact hardware constraints of pixels and colors. While building this I liked the idea that I can fan-out to any retro videogame console or handheld's specifications. I then devised my own declarative language - Demotic - to express the game you want to build as concisely and naturally as possible without implementation detail. To work on different machines, you use relative units, l
