I vibe coded simple Android app that can read/send SMS and simple relay server that acts as MCP for agents. Works surprisingly well and my old android phone from a drawer is doing something useful again.

Feel free to use it if you find it useful. I put it just to a $5 vps. If it's crashed, you should be able to spin up your own instance on your own VPS just in a few minutes.

Webassembly solves this in the Component Model by enabling interop between packages written in different languages. And in my opinion it's sort of the perfect fit for Jumpjet's model: providing a chassis without an engine.

Jumpjet works by defining a very close mapping of WebGPU (and a few other WebIDL features) to WIT so that they can be used in any language that can target the wasm Component Model. Your game then runs as a guest application in Jumpjet's host runtime (powered by wasmtime), which shrinks final bundle size considerably versus something like Electron. Right now a bare bones game in Jumpjet is about 40mb.

Right now the project is in an alpha or possibly pre-alpha state, it's not production ready. On the commercial side, I think there's an opportunity for cloud storage, game server hosting, a package manager and/or marketplace, distribution, and more.

Right now you can target macOS, Windows, Linux, Android and iOS. (I haven't done any real testing on mobile so good luck.) The languages you can use will depend on their support for generating bindings from .wit files. There are a few templates available, I recommend one of the Rust ones.

If you are a game developer or just like tinkering, I'd love for you to try the project out and tell me what you think!

I'm Younes, and I've been building Wolffish for a while now. I want to tell you why...

I love AI. I use it every single day. But every AI agent I tried left me disappointed. Either, it's a CLI tool that is a black box not even the creators understand, or it is a server running with exposed ports inviting all the malice of the internet, or it breaks after every update, or it takes 30 minutes just to set up before you can even say hello, or the worst one yet, you need a course and certificate to begin using the darn thing ...

I just wanted something simple. Something I install, open, and it works. Something my dear grandma could use. Something that actually does real work on my computer — not just generates text I copy-paste somewhere else. Something I could hand over the keys to my private digital setup with peace of mind.

So I built Wolffish. It's a desktop app. You install it and it works out of the box. No server. No setup templates. No bullshit. No broken updates. It's secure — your data stays on your machine. PERIOD! It's private — your data is not saved on some dude's server. It's easy to use, easy to extend, and easy to understand.

It works with DeepSeek, GLM, Claude, GPT, and even runs fully offline with local models. It's free. It's open source. And I use it every single day.

Wolffish is built for a future where open-weights models are frontier-level in intelligence — you download them, run them, and own them. Your digital agent works for you and belongs to you.

I'd love to hear what you think

I'm seeking your help please for suggesting ideas, articles, tactics, and the like for improving ways of working - especially if you have experience and opinions.

We build agents in Elixir. We kept running into the same issue and found there is no observability for agentic systems.

We decided to take the best aspects of LangChain, LangGraph, and DeepAgents and put them into Elixir.

BeamWeaver comes with an OTP-native design and: - agents and tool calling - graph workflows - checkpoints and resumable execution - memory stores - retries, fallbacks, interrupts, and human review - typed streaming events - provider adapters for OpenAI, Anthropic, Google Gemini, xAI, and Moonshot/Kimi - fake/replay models for deterministic tests

We're also building observability on top of it through WeaveScope, which we'll release very soon.

BeamWeaver gives Elixir teams the tools needed to build advanced agentic systems without pushing the hard parts into Python services.

The map currently includes hundreds of startups from Sao Paulo and their job opportunities.

The most interesting thing I've learned so far is how clustered startup activity is in a handful of areas.

I'd love to hear your thoughts.

The EN version: https://www.startupsbr.com/sao-paulo

The web page expires in 30-min but you can access all your builds on our dashboard.

Get started with: brew install milq-ai/tap/sqim

So you basically send quick video / audio clips back-and-forth. And because of the mechanics, it feels conversational and actually replaces meetings (unlike Loom, which is fire and forget): - kill standups - kill the quick syncs or design feedback - kill unnecessary kickoff meetings, announcements - kill code review meetings, talk through complex things

It's helped my team move stupid fast, I'm curious what y'all think. All I will say is Loom is not great for back-and-forth, but this was built for it.

Some other things: - keyboard-first - supported on web, macOS, Windows (I recommend the desktop app for full features) - supports huddles / live calls - supports markdown, and lightweight tasks feature (for noting action items) - supports screen share video

And there's a free tier, so you can get going with a small team.

Mobile is in progress, contact for TestFlight access.

I'll bet some of you may use it to replace slack, teams, zoom. Because it's more effective to speak through issues and resolve them without needing a meeting, and without needing walls of text in slack.
