Este finde ganamos el track de Prosper AI (getprosperai.com) en @hackspain26 con Vortex, un sistema operativo para administradores de clínicas enfocado en llamadas.
Desarrollamos un voice agent con todos los trucos (modelos rápidos, voces naturales, interrupciones, y hasta sonidos de fondo) y se logró.
Tremendo evento. Vamos a continuar buscando la excelencia 🫡
This is actually very cool.
I had already seen a project where someone had hundreds of phones on racks in order to serve a purpose like this one.
I’m curious: how do you guys plan to scale to let’s say, thousands of phones?
Are you planning on having complete data centers or rooms filled with thousands of phones which are connected 24/7?
Can I request a specific device? Such as an iPhone Duo or a Samsung?
The primitives have been there for a while: I started using an MCP to control the iOS simulator for iterating quicker last year.
Very cool!
Agents can now control phones.
Introducing Phone Harness (YC F26)
Let your agent use your personal phone, or its own iPhone/Android in the cloud
> Test and use real mobile apps
> Message and call people
> Grab verification codes for 2FA
Open source. Connect through MCP, CLI, or API.
Get started at phone-harness.com

I can’t believe people are roasting this launch, especially when the technology is this interesting and possibly useful (even for people with disabilities for example).
People take this as a production-grade product and judge it as such when in reality it’s a v0 that is for sure going to be improving over the coming months.
The idea is ship fast, iterate, and improve from customer feedback. I really dig what you guys are doing @the_varunrana @AarushYadav47
Everybody is roasting me in this launch video. It’s easy to hate from the outside. The team has been hard at work helping SFcels like me have the option to not use our voices. This is a dream come true for me. I used to feel bad muttering in meetings. Now it’s a feature, not a bug.
Know the story before you mock the glory 😒

I love the way artifact outputs are grouped in the Claude app now.
It’s very intuitive to see the tangible products of your session on the right panel + any other results coming from it.

SF really is built different. You want to meet people from a company? You reach out or go to an event. As long as you go out of your way to do so, you’ll probably meet.
Maybe the only city in the world where you can do this with essentially any company/organization you want to meet.

Highly recommend you guys to check this out. @rorosaga continued working on this project we had started for a YC Hackathon and became a really cool Mac utility for essentially doing anything on your computer!
it's a skill, not an app. works in claude code, codex, cursor
install: paste this into your agent
"Install hoff-harness from rorosaga/hoff-harness on GitHub"

Anthropic giving us 100 USD for API usage on Max subscriptions is such a W play.
Doing things with it wouldn't be trying before!

A couple of hours ago I said I was working on a coding-agent benchmark mid-flight.
The idea came to me during a Claude session where I gave the agent a key to a relatively undocumented API used within a codebase and asked it some questions.
Magically, it came back with answers.
Currently flying to SF from Madrid, with a layover in Washington ahead of me, and decided to finish a side project I had been working on a long time ago and never got to finish, mid-flight, while posting random stuff as I do it here on X.
Hint: It's a benchmark for coding agents
Second hint: No clue who the guy behind me is
Will keep you posted 😏

What’s your best recommendation for powering a local coding agent if I have an M5 Pro with 48 GB of RAM? 👀

@docusealco is an example of great software. Super easy to integrate into your codebase, OS, and well maintained.
Even for personal use: I had to send a document for someone to sign and my Docusign trial had expired. Signed in to Docuseal and received the signature in 30 seconds.

Anthropic being sleek and providing free API credits to Max users is something I wasn’t expecting. Maybe I’ll now try to put Claude models into some of my projects.
Thanks @claudeai @ClaudeDevs

Excited and grateful to be travelling to SF this Friday for Puentes and to be surrounded by all of these brilliant people. Looking forward to meeting even more!
If you work in biotech, voice agents, AI safety, or otherwise are building something cool, would love to meet :)
Puentes starts this Sunday.
We're flying 15 of the best young engineers from Latin America to SF.
They’re among the most talented in their countries, and they want to be here to compete with the best.
Our goal at @antigravitysf is to help them stay.
Meet the engineers 👇

Today I got a Revolut card with two taps on a screen in the Madrid airport. No questions asked, not even my ID or any documentation.
These guys are built different.

Poured a bit of my heart into my portfolio website ramcav.dev
Shows who I am through a 3D rendering of an NFT I bought in 2021, one of my worst investments ever.
Nevertheless, seems it’s going to not be a bad investment overall for this!

Instinct files are fire. Very easy way to organize yourself on the fly and work on things visually: used it to create a dashboard with people and companies I want to meet in SF when I go next week.
Would love to see a way to persist storage across browsers @noahrshinn
