Mumble Note 0.8.8 is out. Ask Chat a question across your notes and it tells you which notes the answer came from. Select any sentence, tap once, it's a to-do. Get a nudge when a long recording is written up. Also: Starter now includes 10 AI chats a month, and Apple Watch recordings sync reliably even on a bad connection.

Mumble Dictation learns your vocabulary and spells them correctly without guessing.
You fix the same misspelled name every week, and every week it comes back. That's not an accuracy problem. It's a memory problem. Nothing in the audio says whether it's Sean or Shawn, so the tool has to already know which one you mean. Mumble Dictation keeps a personal dictionary on your Mac. It picks up the names and terms you actually use from your own typing. Fix a spelling once and it still holds next month.

$144 a year to type, and it still stops working on a plane. That's the deal with most dictation tools right now. Cloud only,so every sentence takes a round trip to someone else's server before it lands in your doc. We went the other way. Mumble transcribes on device by default, So offline is just a normal tuesday. $50 once, and you keep it. wifi off, just mumble it~

We're on Hacker News today!🎉 Shared how we're solving two things that have bugged us about dictation apps on the market: fake privacy (most still ship your audio to the cloud) and generic ASR that's terrible at your actual vocabulary. Mumble is built to be the most private, and the most fluent in you. Meet us on HN.news.ycombinator.com/item?id…

Dictation just got faster and more accurate in the latest Mumble update. It's now better with names, jargon, and uncommon words, and results show up quicker after you stop speaking 🐳

playing with @_chenglou's awesome work. For startup founders who want some challenge reading Paul Graham's essays. See if you can conquer the long reads at hard game speed. laughtale.gg
My dear front-end developers (and anyone who’s interested in the future of interfaces): I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept): Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

Hit a problem when building a camera-based app with Claude Code: the agent needs to test the camera... but nobody's sitting in front of it. It turns out Chrome has these hidden flags.

--use-fake-device-for-media-stream --use-fake-ui-for-media-stream --use-file-for-fake-video-capture=video.y4m By setting video.y4m as an AI-generated video of a person, the agent can test camera interaction itself now!

Our coding agent ate the entire Mac Studio today. Maxed out RAM with 50 electron instances, and killed the disk with hundreds of worktrees 💀 time to get another one

Taught our coding agent to self-improve and it improved itself… by taking down itself on prod today 😂

it found missing env var during e2e testing → started digging everywhere on the machine → found prod DB url → ran migrate We now copy .env for dev to the worktrees opened for it and also move prod code to somewhere it is hard to touch.

Our internal coding agent was behind a Cloudflared Tunnel. However, it has been conflicting with our company VPN and our AI employee kept disappearing at 3AM every night 😂 So we set it up ourselves @spacemeowx2 @b1ackbinary

With coding agents I'm spending so much more time in the terminal again, feels like the old days. I tried a bunch of terminal apps and found Wave @wavetermdev genuinely useful.

- Smooth split panes with drag-and-drop - Built-in browser widget for debugging (no more cmd-tabbing between terminal and Chrome) - I now keep a notes pane open on the side — super useful when Claude Code / Codex is running and random ideas hit that I need to capture for later
