News for hackers. Stuff that matters.

That's a really cool approach, love it! Treating agent steps as build artifacts (OCI layers) makes total sense for coding agents or offline evaluations where you need filesystem-level reproducibility.

Verist, on the other hand, is aiming for the application layer: lightweight, low-latency observability for production user-facing apps where spinning up containers per-step isn't feasible. I think there's space for both: Dagger/OCI for heavy 'environment' replay, and Verist for semantic 'decision' replay.

Show HN: I built a small OSS kernel for replaying and diffing AI decisions

I’ve been hacking on a small open-source project called Verist and figured I’d share it here to get some early feedback.What kept bothering me with AI features in production wasn’t really how to build them, but everything that comes after: explaining why something happened, reproducing it weeks later, or changing prompts/models without breaking things in subtle ways.Logs helped a bit, but not...

Show HN: Bundle a large codebase for use across multiple LLM apps

I often use Claude Code or Codex for active development, but still rely on ChatGPT / Gemini / Grok for explaining, reviewing, or asking high-level questions.The problem: web-based LLMs don't share context, have strict limits, and re-sending a full repo is expensive and noisy.srcpack lets me package the same codebase into a clean, structured context file that works across different LLMs – with...

Cool project! Been messing with AI agents for code stuff, and this Kanban setup for parallel tasks looks super handy—gonna try it on my next hack. Quick Q: handling token tracking per user/org? Got tons of experience from building UsagePilot (open-core lib for AI metrics). Happy to chat if you need a second pair of hands on that front!

Part-time can be a great fit for developers who use their own stack and stick to a consistent architecture across multiple projects. For instance, I personally begin each of my projects with the same template (https://github.com/kriasoft/react-starter-kit 23k). This approach reduces overhead when juggling multiple tasks, allowing me to seamlessly make changes in one place and effortlessly push and merge updates into various upstream repositories for different clients.

Working as a full-stack software and DevOps engineer since 2001, and launched more than 10 successful products, I can help you with:

- Design, architecture, and build a beautiful web-based product utilizing the latest technologies and proven design patterns

- Optimize the performance and responsiveness of the app by moving the most critical pieces of the code to the CDN edge locations (Cloudflare Workers, KV, R2)

- Optimize hosting costs and dev time by using the serverless platform (Google Cloud Functions, Cloud Run, Cloud SQL, etc.) and Jamstack architecture

- Configure CI/CD for instant and frequent deployments

- Help you build an A+ remote dev team down the road as you grow and scale

I can help you design and develope a GraphQL API server for your web and/or mobile app as well as CI/CD workflows, optimized for serverless infrastructure in Google Cloud Platform. The initial version (first iteration) will be ready and live in under three days! I'm also open for a technical co-founder role in your startup or interested in you as a business co-founder in one of my side projects.

"As any developer will tell you, software development is a marathon, not a series of sprints."

I would argue with that.

Re:Create React Apps with No Configuration on Monday July 25, 2016 @05:33AM (#12157472)
There is an alternative solution that supports CSS Modules, PostCSS and HRM with React Hot Loader. Give it a try! Create a new folder for your project, then run:

    npm install -g react-app-tools
    react-app new
    react-app start

Re:Create React Apps with No Configuration on Saturday July 23, 2016 @02:28AM (#12148600)
I just published a similar tool:

    > npm install -g react-app-tools
    > react-app new
    > react-app start
The idea is to have no configs (though you will be able to configure anything if needed) and a bare minimum package.json:

    {
      "private": true,
      "dependencies": {
        "react-app": "^1.0.0",
      },
      "devDependencies": {
        "react-app-tools": "^1.0.0",
      },
      "scripts": {
        "build": "react-app build",
        "start": "react-app start",
      }
    }
The goal of this project is to provide a simple yet powerful template and tooling for building React-based web apps optimized for CDN hosting in Firebase. This boilerplate is built around modern front-end dev tools such as Babel, Webpack, Hot Module Replacement (HMR), React Hot Loader, CSS Modules, featuring component-based UI architecture with code splitting and async chunk loading.
