Show HN: Sparrow-1 – Audio-native model for human-level turn-taking without ASR

For the past year I've been working to rethink how AI manages timing in conversation at Tavus. I've spent a lot of time listening to conversations. Today we're announcing the release of Sparrow-1, the most advanced conversational flow model in the world.

Some technical details:

- Predicts conversational floor ownership, not speech endpoints

- Audio-native streaming model, no ASR dependency

- Human-timed responses without silence-based delays

- Zero interruptions at sub-100ms median latency

- In benchmarks Sparrow-1 beats all existing models at real world turn-taking baselines

I wrote more about the work here: https://www.tavus.io/post/sparrow-1-human-level-conversation...

Ask HN: Share your personal website

Hello HN! I am putting together a community-maintained directory of personal websites at <https://hnpwd.github.io/>. More details about the project can be found in the README at <https://github.com/hnpwd/hnpwd.github.io#readme>.

As you can see, the directory currently has only a handful of entries. I need your help to grow it. If you have a personal website, I would be glad if you shared it here. If your website is hosted on a web space where you have full control over its design and content, and if it has been well received in past HN discussions, I might add it to the directory. Just drop a link in the comments. Please let me know if you do not want your website to be included in the directory.

Also, I intend this to be a community maintained resource, so if you would like to join the GitHub project as a maintainer, please let me know either here or via the IRC link in the README.

By the way, see also 'Ask HN: Could you share your personal blog here?' - https://news.ycombinator.com/item?id=36575081 - July 2023 - (1014 points, 1940 comments). In this post, the scope is not restricted to blogs though. Any personal website is welcome, whether it is a blog, digital garden, personal wiki or something else entirely.

UPDATE: It is going to take a while to go through all the submissions and add them. If you'd like to help with the process, please send a PR directly to this project: https://github.com/hnpwd/hnpwd.github.io

Ask HN: Weird archive.today behavior?

archive.today has recently (I noticed this, like, 3 days ago) started automatically making requests to someone's personal blog on their CAPTCHA page. Here's a screenshot of what I'm talking about: https://files.catbox.moe/20jsle.png

The relevant JS is:

   setInterval(function() {
     fetch("https://gyrovague.com/?s=" + Math.round(new Date().getTime() % 10000000), {
       referrerPolicy: "no-referrer",
       mode: "no-cors"
     });
   }, 300);
Looking at this blog, there seems to be exactly one article mentioning archive.today - "archive.today: On the trail of the mysterious guerrilla archivist of the Internet" (https://gyrovague.com/2023/08/05/archive-today-on-the-trail-of-the-mysterious-guerrilla-archivist-of-the-internet/), where the person running the blog digs up some information about archive's owner.

So perhaps this is some kind of revenge/DOS attack attempt/deliberately wasting their bandwidth in response to this article? Maybe an attempt to silence them and force to delete their article? But if it is, then I have so many questions. Like, why would the owner of the archive do that 2.5 years after the article was published? Or why would they even do that in the first place, do they not know about Streisand effect?

I'm confused.

Show HN: Webctl – Browser automation for agents based on CLI instead of MCP

Hi HN, I built webctl because I was frustrated by the gap between curl and full browser automation frameworks like Playwright.

I initially built this to solve a personal headache: I wanted an AI agent to handle project management tasks on my company’s intranet. I needed it to persist cookies across sessions (to handle SSO) and then scrape a Kanban board.

Existing AI browser tools (like current MCP implementations) often force unsolicited data into the context window—dumping the full accessibility tree, console logs, and network errors whether you asked for them or not.

webctl is an attempt to solve this with a Unix-style CLI:

- Filter before context: You pipe the output to standard tools. webctl snapshot --interactive-only | head -n 20 means the LLM only sees exactly what I want it to see.

- Daemon Architecture: It runs a persistent background process. The goal is to keep the browser state (cookies/session) alive while you run discrete, stateless CLI commands.

- Semantic targeting: It uses ARIA roles (e.g., role=button name~="Submit") rather than fragile CSS selectors.

Disclaimer: The daemon logic for state persistence is still a bit experimental, but the architecture feels like the right direction for building local, token-efficient agents.

It’s basically "Playwright for the terminal."
