New top story on Hacker News: Show HN: A pager
Show HN: A pager
38 by keepamovin | 22 comments on Hacker News.
Hello HN, I basically don't use notifications for anything. The noise is too much. Slack is too loud. Email is too slow. But sometimes you do need a note in your face. I found myself missing 1990s pagers. I wanted a digital equivalent - something that does one thing: beep until I ack it. So I built UDP-7777. Concept: - 0% Cloud: It listens on UDP Port 7777. No accounts, no central servers. You don't need Tailscale/ZeroTier/WG/etc, it's just easy for device sets. - CAPCODES: It maps your IP address (LAN or Tailscale) to a retro 10-digit "CAPCODE" that looks like a phone number (e.g., (213) 070-6433 for loopback). - Minimalism: Bare-bones interface. Just a box, a few buttons, and a big red blinker. The Tech: It's a single binary written in Go (using Fyne). It implements "burst fire" UDP (sending packets 3x) to ensure delivery without the handshake overhead of TCP. New in v2.2.7: - Frequency Tuning: Bind specifically to your Tailscale/ZeroTier interface. - Squelch: Optional shared-secret keys to ignore unauthorized packets. - Heartbeat: Visual/Audio alerts that persist until you physically click ACK. I built this for anyone looking to cut through the noise—DevOps teams handing off the "on-call IP", or deep-work focus where you only want interruptions from a high-trust circle. I'd love to hear your thoughts on the IP-to-Phone-Number mapping logic (it's purely visual, but I'm really into it). Site & Binaries (Signed for Mac/Win): https://udp7777.com
