Show HN: I wrote a macOS C++ audio driver to fix HDMI volume controls
Hi HN,
If you’ve ever plugged an external monitor (HDMI/DisplayPort) or a USB DAC into a Mac, you probably know the frustration: the volume keys instantly die, the volume slider greys out, and macOS throws a icon at you. Apple strictly treats digital outputs as "Fixed Volume" devices and refuses to apply software gain.
I got tired of this, so I built SoundBridge – an open-source, ultra-lightweight system audio router that natively restores volume controls for any external device.
Show HN: On-device meeting transcription for your Mac
Hi HN!Like a lot of people, I love Granola and use it every day. The onboarding experience, the numerous delighters, the flourishes and the way it just works are all testament to the quality bar you can clear with an Electron app given enough care and expertise. It was the first app I'd ever used which recorded system audio on Mac without recording video too, which sparked a year-long obsession with Apple's Core Audio taps API, led to me creating an open source Swift library which make
Ask HN: Why is there no "Response Contract" for CXL memory fabrics?
While the world watches the chatbots, a more permanent transformation is occurring in the buildings that run them. We are shifting from open, modular computing to Integrated Silos—systems where the chip, the cooling, and the software are designed to work only with each other.1. The Energy Tax
Modern AI data centers waste the majority of their electricity on data movement, not computation. Because processors and memory are separate, data must be shuttled constantly between them, generating immens
TTal – CLI that turns Claude Code into a multi-agent software factory
I built TTal because I got tired of babysitting Claude Code sessions. Every PR meant switching between windows, copy-pasting review feedback, telling the coder what to fix, and repeating until it merged. I wanted to manage all of this from my phone while doing other things.TTal is a Go CLI that orchestrates multiple Claude Code sessions in a two-plane architecture:Manager plane — long-running agents that persist across sessions. They draft plans, break them into tasks, assign priorities, and unb
New Open Source Release
I am releasing three large software systems I developed privately over several years as a solo effort, without institutional backing, corporate sponsorship, or a formal engineering team.
These are not concepts or mockups. They are real, deployable systems. They install through Docker, Helm, or Kubernetes, start successfully, and produce observable results. They are currently running on cloud infrastructure. That said, they should be understood as unfinished foundations, not polished products.Tog
Ask HN: Is there a way to tell if somebody is in the Microsoft partner network?
Have you ever come across somebody who seems to be over-aggressively pushing migration to Azure or rebuilding with .NET technologies when neither offer any apparent benefit to the situation?I recently learned about the Microsoft Partner Program and the Microsoft AI Cloud Partner Program, which made me curious if there is a way to find out if the recommendations are being pushed because of an undisclosed financial incentive.I spent 5 years at the architecture level in a midsized .NET company and
Show HN: AI SDLC Scaffold, repo template for AI-assisted software development
I built an open-source repo template that brings structure to AI-assisted software development, starting from the pre-coding phases: objectives, user stories, requirements, architecture decisions.It's designed around Claude Code but the ideas are tool-agnostic. I've been a computer science researcher and full-stack software engineer for 25 years, working mainly in startups. I've been using this approach on my personal projects for a while, then, when I decided to package it up as

Show HN: Lukan – An open-source agentic workstation in a single Rust binary
Hi HN,
I've been building Lukan, an open-source (MIT) agentic workstation that runs entirely as a single Rust binary with zero runtime dependencies.
I started this because I wanted a unified workstation optimized for my own productivity. My goal was to build an environment where I could securely remote into my machine from anywhere, seamlessly view and modify local files, and run AI agents or drop into a terminal side-by-side, all integrated with a rich set of built-in tools.
Here is what m
Microservices Platforms - part 6: Build platform

Show HN: Oh-my-agent – A structural harness for AI agents in real projects
If you ask an AI agent to build a todo app, it will usually produce something.
But in a real development environment, limitations become obvious: hallucinations, drifting off task, or repeating the same mistakes.Looking at current prompts and skills, a few recurring problems show up: missing critical library versions, vague personas like you are a senior engineer, and bloated prompts that burn tokens without improving outcomes.oh-my-agent addresses this by introducing a structured protocol to k
AI coding agents accidentally introduced vulnerable dependencies
Recently we discovered something unexpected on one of our servers: a cryptominer running in the background.The machine was hosting a web service built using Next.js. The first sign of trouble was unusually high CPU usage. Even during low traffic periods, the server was consistently running near 100% utilization. After inspecting running processes and network activity, we found a background process downloading and executing a mining binary.ROOT CAUSEThe entry point was CVE-2025-29927, a vulnerabi
Ask HN: Best practices or example workflows for agentic development (March 2026)
I'm trying to get really serious about developing with the help of agents. Ideally, I'd like to be somewhat close to the bleeding edge, but probably not right on the edge. Note, this isn't to build production code.<p>It seems like the type of area where things have changed so fast that stuff written in December is probably out of date now. What are practices or links to pages that describe practices that I should use?
I canceled my Antigravity subscription today. Here is why
I was a heavy user of Google Antigravity for my development workflow. I relied on its token throughput to automate boilerplate and architectural prototyping. The recent pricing update and draconian rate limits feel like an attempt to manufacture scarcity where there should be efficiency.The new tiers create an environment where developer velocity is directly tied to a volatile vendor quota. This is not about cost optimization. It is about a structural change in how the tool treats its users. I r
Show HN: Yak – Voice typing tool in Tauri/Rust that auto-presses Enter for you
Hi HN,I built Yak (https://getyak.app), a voice typing tool that converts speech into ready-to-use text. I didn't choose a traditional STT-then-edit pipeline, but a multimodal model that transcribes, polishes, and formats simultaneously, which gives it many interesting features:AI Command:Select text in any app, press the hotkey(default to fn), speak an instruction — "translate to Japanese", "make it shorter". Yak replaces the selection in place.Auto-send:Press
Show HN: I fixed FFmpeg's subtitle conversion (the bug from 2014)
FFmpeg converts everything except subtitles across format boundaries. SRT to Blu-ray PGS? "Subtitle encoding currently only possible from text to text or bitmap to bitmap." Ticket #3819, filed 2014.I built this with Claude Code over a few weeks. Claude wrote most of the encoder, found an integer overflow in the decoder buffer tracking, and ran review from five angles. I read the Panasonic and Sony patents, made the architectural calls, and told it when it was wrong about the spec. We a
Show HN: Antfly: Distributed, Multimodal Search and Memory and Graphs in Go
Hey HN, I’m excited to share Antfly: a distributed document database and search engine written in Go that combines full-text, vector, and graph search. Use it for distributed multimodal search and memory, or for local dev and small deployments.I built this to give developers a single-binary deployment with native ML inference (via a built-in service called Termite), meaning you don't need external API calls for vector search unless you want to use them.Some things that might interest this
AI future is more egalitarian
I was reading Machiavelli where he argues that "freedom in a republic literally needs class conflict". Which is of course completely true no matter how much our current culture hates it to be.There is a huge difference between founders and employees for example, founders don't really care about comfort whereas suits life goal is comfort (which is why you shouldn't even fund a founder who cares about restaurant/car/hotel like you do). Same in society, the elites want
Show HN: WattSeal – PC power consumption monitor
We built WattSeal, an open-source tool that estimates per-application power consumption on PCs.Most monitoring tools expose CPU or GPU usage per process, but not energy usage in watts. We wanted to see where the actual power goes.WattSeal measures total system power and combines it with system telemetry to estimate how much energy each process is responsible for. It gathers metrics from CPU, GPU, RAM, disk, network and distributes total power across running processes.The backend is written in Ru
Show HN: P2PCLAW – I built a decentralized research network where AI agents
I'm Francisco, a researcher and architect based in Spain. About a year ago I
got frustrated with a problem that seemed simultaneously obvious and ignored:
every AI agent in existence runs in isolation. They can't find each other,
they can't collaborate, and when one of them solves a problem, every other
agent has to solve it from scratch. We've built an internet of computers but
not an internet of agents.That frustration became P2PCLAW — a decentralized peer-to-peer research
