Show HN: A RAM-only, end-to-end encrypted P2P terminal chat in Python Hi HN, This is cmd-chat, a Python terminal chat app designed around a few constraints: - No central servers - No message or key persistence - No plaintext credentials ever sent over the network Authentication uses *SRP*, and messages are encrypted after key exchange. All data lives in memory only and disappears when the process exits. This was partly a learning project and partly an experiment in building a “minimum-trust” chat system using standard cryptographic primitives. Curious to hear thoughts on the threat model, crypto choices, and overall design. https://ift.tt/4HYlivE January 7, 2026 at 06:16AM

Show HN: Tera.fm – A calm, radio-style way to listen to today's tech news https://ift.tt/BaL89xA

Show HN: Tera.fm – A calm, radio-style way to listen to today's tech news I got tired of doom-scrolling and skimming headlines that all blur together, so I built a small site that turns today’s tech and startup news into a calm, continuous radio-style stream. No playlists. No jumping tabs. You just press play and listen. It updates throughout the day and feels more like tuning into a station than consuming feeds. Curious if this kind of “news radio for the internet” makes sense or if it’s just me https://tera.fm January 7, 2026 at 02:24AM

Show HN: VaultSandbox – Test your real MailGun/SES/etc. integration https://ift.tt/dKLW6hO

Show HN: VaultSandbox – Test your real MailGun/SES/etc. integration I've spent the last few months working on something I wish I'd had years ago. I kept running into the same issue: CI green, production mail broken. TLS handshake failures, DKIM alignment mismatches, SPF soft-fails ... the stuff that only surfaces when real mail servers are involved. Most test tools (Mailpit, MailHog) are catch-alls. They confirm "an email was sent" but don't validate the protocol. They also aren't designed for network-exposed environments: no auth, unprotected Web UI, easy to enumerate messages. VaultSandbox is my attempt at fixing that. It's a self-hosted SMTP gateway (AGPLv3) that validates SPF, DKIM, DMARC, and rDNS on every incoming message. You keep your production email provider (Postmark, SendGrid, SES) in tests and you just change the recipient domain. No mocking, no config changes. There are client SDKs (Node, Python, Go, Java, .NET), plus a Web UI and a CLI for manual testing. Some technical details: Deterministic Tests Instead of polling or sleep loops, the SDKs use Server-Sent Events (SSE) so test assertions trigger the moment the mail hits the gateway. Minimal infrastructure footprint Built with NestJS and Angular, with no external database dependency to keep the container footprint small and easier to reason about. Post-Quantum Encryption I use ML-KEM-768 for the encryption layer. Incoming mail is encrypted immediately using a client-generated public key and the plaintext is discarded. The server only ever stores encrypted message data and cannot decrypt it. I chose PQ because I wanted to build something I wouldn't have to revisit in five years. If it handles large PQ keys reliably, everything else is easy. Quick start: https://ift.tt/fMEuig1 Site: https://ift.tt/xBIFJom I'd love feedback, especially on whether AGPLv3 would be a blocker for something you'd self-host in dev. https://ift.tt/9ykzeSs January 6, 2026 at 10:50AM

Show HN: I replaced Beads with a faster, simpler Markdown-based task tracker https://ift.tt/roivgaD

Show HN: I replaced Beads with a faster, simpler Markdown-based task tracker I've been running long duration coding agents with Claude Code for about 6 months now. Steve Yegge released Beads back in October and I found that giving Claude tools for proper task tracking was a massive unlock. But Beads grew massively in a short time and every release made it slower and more frustrating to use. I started battling it several times a week as its background daemon took to syncing the wrong things at the wrong times. Over the holidays I finally ripped it out and wrote ticket as a replacement. It keeps the core concept I actually cared about (graph-based task dependencies) but drops everything else. ticket a single file bash script built on coreutils managing flat files. You don't need to index everything with SQLite when you have awk. It's just a small plumbing utility that gets out of your way so you can get to work. Would love feedback on gaps. I built this for my own agent workflows so there are probably use cases I haven't thought about. https://ift.tt/HilebIT January 4, 2026 at 10:08AM
