Objections

  • Source code is closed, so users cannot verify the binaries.

    From 2 comments
    • Is the source available? What is presented is a machine-generated website with very little meaningful information and mystery binaries for three platforms. PS: The "SHA256…

    • Signing, notarization, and hash checking just ensures that what I run is the thing that you meant for me to run. Source availability permits me to ensure that what I run is the…

  • Mapping IPs to phone-like CAPCODEs could cause confusion, especially with 911-like numbers.

  • Better documentation explaining what the project is on the site.

    From 2 comments
    • What is "UDP-7777"? Is it some kind of software? What does it do exactly?

    • The website does not say anything. The website offers me to download a .zip file. Why should I download a .zip file? As far as I know, a pager is supposed to be a physical object?

  • Stronger authentication, such as signatures instead of plain-text secrets.

    • > It drops every message that doesn't start with your secret:: Depending on how internet-proof you want to make this, I wonder if it might be better to sign with a secret and…

    • For anti-spam, the general use case is use of Tailscale/Zerotier where you are in control of your network. If you are on public internet and have 7777 open then you can use the…
