   Checksum.sh verify every install script▲119

   The pattern of downloading and executing installation scripts without verifying them has bothered me for a while. I started messing around with a way to verify the checksum of scripts before I execute them. I've found it a really useful tool for installing things like Rust or Deno. It's written entirely as a shell script, and it's easy to read and understand what's happening. I hope it may be useful to someone else!

    Pu.sh – a full coding-agent harness in 400 lines of shellfree▲92

    I originally was just messing with pi-autoresearch. Gave it a sample task to build the most portable coding agent. First cut was 6 KB of shell. Great for one-shots, unusable interactively. I was shocked it actually worked. Started building up -- adding features — but with a self-imposed rule: no new dependencies, and sub 500 LOC. This thing had to be truly portable. Just sh, curl, awk. System primitives only. Which means I did some genuinely disgusting things in awk, including JSON parsing and the OpenAI Responses tool loop with reasoning items carried across turns. It's now ~400 lines. In…

    Test your WireGuard connectivity and see global stats, no client needed▲43

    Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…
