I explained that adding multiples of seven doesn’t change the weekday, only the remainder matters. Not the easiest concept for a four-year-old.28 Feb 2025 13:10 +0000at://did:plc:figtsonadcpr2nbmakv7sz36/app.bsky.feed.post/3ljai6q2cc22vhttps://bsky.app/profile/dhoelzgen.dev/post/3limbkgsblc2lYesterday, I released a tiny MCP server that allows Cursor Editor to get up-to-date version information for external Hex dependencies. Someone suggested doing a version for #RubyOnRails, so I built a more generic version that supports Ruby Gems, Hex, PyPI, and NPM. dep-mcp.9elements.com https://dep-mcp.9elements.com/20 Feb 2025 12:18 +0000at://did:plc:figtsonadcpr2nbmakv7sz36/app.bsky.feed.post/3limbkgsblc2lhttps://bsky.app/profile/dhoelzgen.dev/post/3lijnibsp7k2hI am currently using Cursor to build a #elixirlang #phoenix application. It kept adding outdated package versions, so I decided to build an MCP server to solve this issue.
