Dev Systems - Building Systems That Scale

Ask HN: Am I holding it wrong?

I've been steadfastly trying my best to incorporate the latest-and-greatest models into my workflow. I've been primarily using Codex recently. But I'm still having difficulties.For example: no matter what I do, I can't prevent Codex from introducing linter errors.I use tabs instead of spaces for indentation. It seems like the model is massively weighted on code written using spaces (duh). Despite having a very well articulated styleguide (that Codex helped me write after exam

Forget chatbots. This is about building an "AI Being" (AIB)

After spending weeks analyzing the Moltbook leaks and the systemic failures of unaccountable AI agents (as warned in I Am Your AIB), I thought we were headed straight for a black-box catastrophe.I was wrong. I just stumbled upon something that changes everything.There is an open initiative that isn't just talking about "AI safety" in abstract terms. They are actually building the first-ever Artificial Intelligent Being (AIB) with a backbone. This is the "Genesis Moment"

Show HN: Microagentic Stacking – Manifesto for Reliable Agentic AI Architecture

I’ve spent the last couple of years deploying LLM agents in production environments, and I’ve consistently hit the same wall: the 'Cognitive Monolith' (or what I call the Big Ball of Mud AI).We are currently seeing a lot of hype around 'autonomous agents' that are essentially 3,000-word prompts with access to 20 tools. In my experience, this doesn't scale. It’s impossible to unit test, observability is a nightmare, and the 'vibe-based' engineering makes it a li

Ask HN: Best practices for AI agent safety and privacy

tl;dr looking for any links, resources or tips around best practices for data security, privacy, and agent guardrails when using Claude (or others).My journey over the past few years has been one of borderline AI skeptic for its use in coding to having tried Claude Code a month ago and being unlikely to ever go back to coding big changes without it. Most queries I would have used search for in the past are now done in AI models as a first step.However, one thing that concerns me is whether I am

Camera based true random number generator Beta

I’m an electromechanical engineer who usually tinkers with RPis and Arduinos more than software, but a few weeks ago I went down the rabbit hole of randomness. I read about Cloudflare’s lava lamp wall and thought: if they’re ultimately using cameras, why not use the image sensor noise directly?Modern CMOS sensors produce a lot of grainy, unstable pixels—even when pointed at a static scene. You can film the same white wall at 30 fps and never get an identical frame. That felt like a decent physic

Show HN: Software Design – ADRs, arch tests, patterns

I kept collecting software design bookmarks for years — repos, articles, books — but never organized them. Most "awesome" lists for architecture cover the "monolith vs microservices" debate. I wanted something focused on the code-level side: how to actually structure modules, enforce design rules in CI, and document decisions. I went through ~300 resources and kept 106 across 9 categories. A few sections I haven't seen elsewhere:Architecture Decision Records — 14 real-wo

Edit and delete messages without rewriting your history layer

Editing or removing a message after it’s been published sounds simple. In realtime systems, it usually isn’t.Once a message has been delivered to multiple clients, cached locally, and written into history, changing it safely becomes a coordination problem. Clients need to agree on what’s current. History needs to stay consistent. Reconnects and refreshes can’t bring back stale content.That’s why many systems treat messages as immutable by default.Today, Ably Pub/Sub adds support for editing and

Show HN: Live architecture docs using AST parsing + LLM

I am working on a tool called MaiMap which combines static code parsing with LLM-based analyses to generate architectural docs and diagrams for microservices.The link I have posted here is to a demo of what the generated docs look like. My plan is to provide this knowledge to user's LLMs so you can ask it questions about your distributed system. I would also like to have this read documentation and incorporate that into its knowledge base. Any feedback here would be much appreciated - would

Show HN: A Distribution Framework for founders who can build but can't sell

6 months ago I launched my AI customer support widget on Product Hunt and other directories. Got some traction but ended up with 5 free users and 0 paying customers.I'm a software engineer with 10+ years of experience, building on the side after my 9-5 in Romania. I could ship a full product in a weekend with Claude Code. But I had zero idea how to get it in front of people who'd pay for it.I didn't even know what an ICP was at the time. Didn't know if SEO was worth doing or

Show HN: Agent framework that generates its own topology and evolves at runtime

Hi HN,I’m Vincent from Aden. We spent 4 years building ERP automation for construction (PO/invoice reconciliation). We had real enterprise customers but hit a technical wall: Chatbots aren't for real work. Accountants don't want to chat; they want the ledger reconciled while they sleep. They want services, not tools.Existing agent frameworks (LangChain, AutoGPT) failed in production - brittle, looping, and unable to handle messy data. General Computer Use (GCU) frameworks were eve

Show HN: Double blind entropy using Drand for verifiably fair randomness

The only way to get a trust-less random value is to have it distributed and time-locked three ways, player, server and a future-entropy.In the demo above, the moment you commit (Roll-Dice) a commit with the hash of a player secret is sent to the server and the server accepts that and sends back the hash of its secret back and the "future" drand round number at which the randomness will resolve. The future used in the demo is 10 secsWhen the reveal happens (after drand's particular

Show HN: DevProof – Verified developer portfolios using Code Complexity and AI

Hi HN,I'm Dhruv. I built DevProof because I was tired of guessing which "Senior Engineer" actually understood distributed (or complex) systems versus who just pasted code from tutorials. GitHub activity charts (green squares) measure effort, not engineering depth.What it is: DevProof is a portfolio generator that audits your actual code. It follows a "Proof of Work" model: it pulls your source code, runs it through a 2-step verification pipeline (AI + Static Analysis), a

Securing A Multi-Agent AI Solution Focused on User Context & the Complexities of On-Behalf-Of.

How we built an enterprise-grade multi-agent system that preserves user identity across AI agents and DatabricksIntroductionWhen building AI-powered applications for the enterprise, a common challenge emerges: how do you maintain user identity and access controls when an AI agent queries backend services on behalf of a user?In many implementations, AI agents authenticate to backend systems using a shared service account or with PAT (Personal Access Token) tokens, effectively bypassing row-level

Show HN: Open-source Liquid sections for Shopify themes

Hi HN, I've put together a collection of open-source Shopify sections (Liquid, CSS, JS) that can be added to themes. I built this because I found that while Shopify is great, standard themes often lack specific sections, and custom development can be expensive for small merchants. I wanted to create a repository of high-quality, copy-pasteable sections that developers can use to speed up their workflow or merchants can use to enhance their stores without apps. I’d love to hear your feedback

Show HN: SpecOps – Spec-Driven Development for Infrastructure as Code

Hi HN,I built SpecOps, an open-source CLI framework inspired by GitHub's Spec Kit approach, that brings Spec-Driven Development to Infrastructure as Code.The problem: Most IaC projects start with ad-hoc scripting — jumping straight into Terraform/Ansible without clear specs.SpecOps enforces a structured workflow:Idea → Specification → Plan → Tasks → ImplementationIt works with AI coding agents (Claude Code, GitHub Copilot, Cursor, Gemini CLI, Windsurf, and 12+ others) to guide you thro
