Team Documentation (GDrive vs. Markdown)

Hacker News - Fri, 08/07/2026 - 1:10am

How does your team manage your team documentation? At work we use Google Docs and its MCP, and most of my colleagues use Codex to write any documents. For my side projects, we use markdown in repo mostly.

Curious what your team uses for primary documentation for day to day work.

Show HN: Sidebar – a private ESP32 intercom for five kids, no accounts

Hacker News - Thu, 08/06/2026 - 11:31pm

Hello all - Inspired by many who build/assemble for their daughters/sons, I took cue and assembled a two-way communication between my son and his friends. Nothing spectacular. Just basic stuff to talk.

He is eleven and doesn't have a phone. I wanted him to talk to his friends without an account, a feed, or an algorithm in between, so I built five ESP32-S3 touchscreen units, one per kid. Tap a friend's name, their unit rings. Tap Everyone, they all ring.

Each unit dials outbound to a relay I run, so no house opens a port. Audio is uncompressed 16 kHz PCM in 20 ms frames, AES-256-GCM with a fresh key per call, over UDP with an encrypted-WebSocket fallback. To be precise: encrypted to my relay, not end-to-end. No rooms, no recordings, no free-text contacts; the roster lives in a server-side allow-list.

I'm a PM, engineer by degree but not by profession - let alone a firmware engineer. I assembled this with Claude as the engineering partner, which is why the write-up includes what went wrong: I shipped an OTA that boot-looped my son's board, and separately "diagnosed" a Cloudflare outage that didn't exist because I tested from the wrong vantage point. Echo is still unsolved.

The enclosure was designed in FreeCAD by my son (11); the STLs are in the repo.

It was a fun and exhilarating work for me and my son - like most of you would have experienced.

Looking forward for your responses/feedback.
