Show HN: Whodunit? Solve a daily AI-written Mystery https://ift.tt/AyBnmDU

Show HN: Whodunit? Solve a daily AI-written Mystery Whodunit started as a pen-and-paper game for family game night. It evolved into a web app with a new mystery every day. The mysteries are all written by LLMs. Some are better than others, but most work nicely. The web app is written in go with templ HTML templates, HTMX for on-page interactivity, SSE for content updates, and a turn-based game engine written as a Temporal workflow.

Show HN: Omacosy – Omarchy-style tiling desktop for macOS, no SIP https://ift.tt/ib3VwNq

Show HN: Omacosy – Omarchy-style tiling desktop for macOS, no SIP I have been using omarchy on my tower since nearly a year now, shortly after it was released first. I really love the experience I am having with it but I still use my macbook for daly work, so I wanted to recreate a similar experience on it. Thats why I created omacosy, a setup for tiling windows, custom menu bar, some themes from omarchy, focus follows mouse, focus rings around windwos, some mac flavors with trackpad events and a custom mission control overview for your workspaces. I used AeroSpace over yabai for the tiling window manager because I didnt wanted to compromise on SIP which is a mac security feature. It is supposed to be keyboard first like omarchy to move windows organize workspaces etc The setup runs around 157mb of ram and consists of AeroSpace, Karabiner (for the super key), and five small self build swift binaries. I am running it daily on my M1 max macbook, currently on macOS26. I havent tested it much on other macbooks or macOS versions. The install script creates a manifest file to backup what was installed before and what it installed itself, the uninstall script takes that into account to clean up the macbook to exactly the state it was in before. It needs quite some permissions for it sfunctionality which I layed our in the project readme. I wanted to be really transparent about which permissions it uses and for what reason. I would love to get some feedback or see people trying it out and hearing your opinion. Mostly about what still doesnt feel smooth in the experience or if you find any performance issues. https://ift.tt/PVdecaA August 20, 2026 at 09:12PM

Show HN: Voidleap Code – agentic IDE, own harness, swap models mid-conversation https://ift.tt/K2O94Uk

Show HN: Voidleap Code – agentic IDE, own harness, swap models mid-conversation We wanted to build a development environment that can make you a better agentic engineer, not a tool that makes money when you waste tokens. A tool where you can swap models between turns, edit the context, and see every agent action. To do it, we had to build our own harness. Free to use. We don't sell inference, so bring your own key. The sore spot is Claude subscriptions. We can't support them because of Anthropic's terms. The app runs on your machine, and your data never touches our servers. We've been building Voidleap Code using Voidleap Code since January. We didn't rush to launch, but instead focused on getting the architecture and package just right. There are still more features to build, and more polishing to do, but it's ready for you to try. Judge it for yourself and tell us what you think. https://voidleap.com/ August 19, 2026 at 01:40AM

Show HN: macOS data protection keychain for Electron apps https://ift.tt/lfFCMq7

Show HN: macOS data protection keychain for Electron apps Hey HN, I've been working on Hansel [1] (an encrypted personal data store you can query with agents), and there wasn't a good way to use the modern macOS Data Protection Keychain. Electron's safeStorage [2] uses the legacy file-based keychain, which allows other apps/agents to query it with the `security` CLI. Not great when you have a dozen agents running in the background! The Data Protection Keychain is nice because it limits access via code-signing access groups and lets you set access rules like Touch ID and/or password. 1: https://hansel.so/ 2. https://ift.tt/YPKrQfi https://ift.tt/xrnGYSs August 19, 2026 at 12:25AM
