Show HN: Closed Rings – A CLI-first time tracker for developers Hi, HN. I built Closed Rings. A developer-friendly, AI-agent-first time tracker that integrates with my workflow. I wanted something that lives in my terminal and my coding agent. You can run `rings start "OAuth 2.0" -m "Start integrating OAuth 2.0"` when you start a new task and `rings close` when you're done with your current work. In between, it tracks context switches. You get a stand-up-ready summary, a focus report (longest focus block, number of context switches, time per project), and an export grouped by project or day. You can also ask your AI agent: _Start tracking "OAuth 2.0"._ Or track retroactively: _Track a 1-hour meeting I forgot to track this morning at 8._ The MCP has a comprehensive set of tools. This is primarily for consultants or freelance developers who want to start tracking their time right away. The CLI is pretty straightforward, and the MCP allows you to do everything you can do in the dashboard. Want to integrate it in your own systems? Just create an API key and start communicating with the API. The stack is pretty simple: Ruby on Rails (MCP + API), Go (CLI). The pricing is also pretty flat: $7/mo ($60/year). My first product. Feedback welcome. https://ift.tt/xfawYqo May 19, 2026 at 02:29AM

Show HN: MyUUIDshop, Generate UUIDs and never worry about duplicates https://ift.tt/9D6v2or

Show HN: MyUUIDshop, Generate UUIDs and never worry about duplicates In response to some recent discussion here and on X about a company having an in house uuid microservice and team dedicated to it. At first that was made fun of, but further discussion revealed in fact sometimes uuids can collide due to improper entropy seeding most likely. In order to ensure that UUIDs are unique, we store each generation in a database, then check new generations against it to ensure they are not previously generated. As well, there is an API through which you can check if a UUID is present in the database. Paid options available for heavy use. Enjoy! https://myuuid.shop May 19, 2026 at 02:17AM
