• Sokit 0 open listings

  discussion=https://news.ycombinator.com/item?id=49744527, title=Show HN: Sokit – a LangChain like harness for Jev (or other System 1 models), Full disclosure, it was coded with AI, I don't claim otherwise. But I wanted to test out tool calls and iterative problem solving using Jev and needed a simple library/framework/harness to do that. SOKIT (System One Knowledge, Instructions and Tools) is the result and I figured it might be useful for more people than just me. I will likely be extending it a bit as I find more ways to use Jev, but it works as is for certain use-cases and it's easy to extend.

• SolidPing 0 open listings

  discussion=https://news.ycombinator.com/item?id=49656831, title=Show HN: SolidPing — open-source uptime monitoring, agents inside your network, SolidPing is a single Go binary, AGPL-3.0 — 40 check types, status pages, incidents, on-call escalation, and sub-minute intervals that aren't paywalled. I loved Better Stack, and then the free plan kept getting thinner. What finally pushed me over: incidents used to get one Slack thread each, so an outage lived in one conversation instead of a stream of disconnected messages. That went away. I wanted it back, so I built my own. The part I'd most like torn apart is the agents. You run one inside the network you want watched and it dials out over a WebSocket, so there's no inbound port and no firewall hole. On first start it generates its own keypairs and keeps the private halves — Ed25519 for identity, an X25519 (age) recipient that the server seals check credentials to. So the credentials for a private check are encrypted for that agent, and the server storing them can't read them. All of it is open source: the agents, WhatsApp alerts, SSO, every check type. Nothing held back for a hosted edition. Self-hosting is genuinely easy, and I depend on it, https://status.solidping.io is a second SolidPing running on fly.io that watches the cluster hosting the first one. A monitor that lives inside what it monitors isn't a monitor. I've maintained a small Go FTP server library for 10 years (github.com/fclairamb/ftpserverlib), so open source isn't a marketing decision here. Demo, no signup: https://solidping.io/demo

• Sparrow-2 0 open listings

  discussion=https://news.ycombinator.com/item?id=49612459, title=Show HN: Sparrow-2 – Noise cancellation isn't designed for conversational AI, Hey there, I’m Brian. I've been shipping conversational models at Tavus for the past two years. I want to tell you about our latest audio-understanding/turn-taking model: Sparrow-2! It’s a new category of model and a unique new approach to conversational flow understanding.Earlier this year we launched Sparrow-1, (at the time) our SoTA turn-taking model. Since our Sparrow-1 launch, I’ve spent a lot of time listening to humans talking and trying to really understand how people know when to talk, when to listen, and when to wait. I’ve also been hunting down failure modes of the current SoTA models. And while Sparrow-1 is great, there are some failure patterns I see. We tried solving the problems with existing approaches, but solving one problem only created another.Current turn-taking models (like Sparrow-1) use noise cancellation to strip background sound, leaving only basic prosody and phonetic word cues to manage turns. Non-transcribable audio such as breathing, sighs, and environmental sounds provides critical context that humans use to hold or signal turn changes. This is because these models are primarily focused on verbal activity. Treating non-verbal audio as background noise discards vital conversational data, destroying the natural flow of dialogue.Now, with Sparrow-2, instead of modelling just the primary speaker’s verbal audio, we’ve trained a model with access to all the sounds and let it decide what matters and what does not when it comes to conversational flow. Our new model continuously streams in audio and is able to understand semantics, prosody, timing, speaker identity, sighs, breaths, back-channels, interruptions, background speech, and unintelligible audio with the goal of understanding what the agent should do given the state of the audio. Sparrow-2 recently ranked #1 on Sesame’s new Turnbench, but that’s only part of the equation when it comes to good conversation flow.Turn-taking is good for timing, but models should provide more information downstream especially in situations where noise impacts conversational quality. Sparrow-2 fits into our larger model family and is semi-duplex. For example if the user is in a room that’s too noisy, now the bot can ask the user to move to a quieter space. It also considers the timing of sound in relation to the AI speech as well as the user’s. This helps it to disentangle normal speech from interruptions and back-channels.Another added benefit of our approach to Sparrow-2 is to finally crack the cocktail party problem: how to have human-like conversations 1:1 in noisy environments, without losing the signals we rely upon for conversational flow. By allowing all sound to be learned, the model naturally learns to focus on what matters and transcends the rest. Noise understanding lets voice AI filter out background speech and ambient chaos, whether it's a kiosk in a noisy lobby, a shop assistant on a busy floor, or an interviewee in a cafe. When noise overwhelms the audio, the AI behaves like a human: it simply asks you to speak up, move, or swap mics.I’d love for you guys to give it a try and let me know what you think and feel. You can try it here: https://sparrow2.tavuslabs.org/I also wrote up some technical details about the model architecture here: https://www.tavus.io/blog/sparrow-2

• Stage Captions 0 open listings

  discussion=https://news.ycombinator.com/item?id=49709975, title=Show HN: Stage Captions – streaming browser audio into live event captions, Originally, I am .NET software engineer working corporate job with microservices on RMQ and REST APIs. But I always had the desire to experiment with some different tech on the side. After my friend shared his plans of helping facilitate medical conference which was bilingual and some of the audience members might feel missed out due to English not being their first language, I thought it's a nice opportunity to create a tool for it with my cofounder who is a frontend engineer. For me it was a chance to work with audio, ASR, accessibility and websockets - something fresh and new. Another inspiration was Formula 1 captions which I noticed during their broadcasts, which are generated in real-time. After digging a bit into underlying technology I thought to create something similar for event organisers and AV teams. Not as a replacement for human interpreters, but as a more accessible alternative to quite costly hardware options. That's how Stage Captions was built. Audio comes from browser, gets streamed via WSS to backend, goes through processing pipeline and then captions are streamed back to viewers. Those captions can be displayed on venue TVs, opened on attendees devices by scanning QR code or incorporated into a broadcast using OBS for example. Obviously, ASR and MT models are third party and not created by me, but there were still some fun challenges like scaling websockets (it was trickier than just adding one more container on load), audio processing (finding optimal chunking and buffering approach) and obviously stabilization algorithms for partial transcription / translation results. As a developer I was happy to experiment with tech stack which is different from my daily work. And as a human it felt right to build something which can make in-person events easier to follow for non-native speakers and deaf/hard of hearing attendees.

I also added built-in MCP tools that let agents create diagrams, turn GitHub issues into sticky notes, and more. I control most things with my voice. It can run Parakeet locally, or you can switch to GPT Realtime instead. I tried to keep everything super minimal and clean. I’d say it’s worth checking out. Cheers!

They look good at first glance but it's not actually a physically realizable pattern when you look at the details. The way it works is pretty simple, you use text (& optional images) to create and edit patterns. There's also a built in editor to manually change any of the stitches. It's not perfect but with a few manual edits, she's been able to create some awesome patterns. Here are a few one the ones she's made:
