Show HN: Powering React with Python (WASM)

Hacker News - Tue, 04/22/2025 - 12:58pm

A few weeks ago, Theo T3 posted a read-through of a Medium article showing how to augment an AngularJS website with WebAssembly in order to compute a factorial.

I've been building a general(-ish) purpose Python compiler, mainly focused on numerical computing and AI inference. I figured it would make a good exercise to create something similar, this time with a bit more number crunching.

I vibe-coded a Lightroom-esque image editor UI (thanks Claude!) then wrote a tiny Python function that does a contrast adjustment using PyTorch. It gets compiled to wasm with what I'm building, and runs blazing fast thanks to vectorized 128-bit wasm intrinsics (I wonder if we'll get 256-bit anytime soon).

Play with it here: https://github.com/olokobayusuf/photo-editor . I'm exploring building a WebGPU-powered tensor framework to go even faster. Let me know what you think!

Anyone scaling ArgoCD across multiple clusters?

Hacker News - Tue, 04/22/2025 - 12:57pm

I’ve been using ArgoCD with GitHub Actions for GitOps, and it worked well in the beginning. But once I started managing multiple clusters, it got more complicated:

- Syncs slowed down

- Had to spin up separate ArgoCD instances

- CI/CD felt disconnected from the GitOps flow

Would like to hear how others have approached GitOps at scale. Did you stick with Argo and layer on tooling? Or move to something like Flux or a custom setup? Any lessons learned are welcome.

Show HN: I built a Ruby gem that handles memoization with a ttl

Hacker News - Tue, 04/22/2025 - 12:51pm

I built a Ruby gem for memoization with TTL + LRU cache. It’s thread-safe, and has been helpful in my own apps. Would love to get some feedback: https://github.com/mishalzaman/memo_ttl

Show HN: I replaced my devs with AI agents – and it worked

Hacker News - Tue, 04/22/2025 - 12:40pm

I run a small AI company in Luxembourg. We started out as a consulting studio, building custom tools for clients — mostly boring things like dashboards, reporting modules, and CRUD backends.

At some point I realized we were building the same things over and over again. Not in a copy-paste way, but in a “we could generate 80% of this” kind of way. So last year, I ran a live-fire experiment: I asked Claude 3.5 and DeepSeek to build a small admin panel, with tests and API docs, from a plain-language spec.

The result: not great, but usable. It gave us the idea to stop typing code altogether.

Now, at Easylab AI, we don’t write code manually anymore. We use a stack of LLM-powered agents (Claude, DeepSeek, GPT-4) with structured task roles: • an orchestrator agent breaks down the spec • one agent builds back-end logic • another generates test coverage • another checks for security risks • another synthesizes OpenAPI docs • and humans only intervene for review & deployment

Agents talk via a shared context layer we built, and we introduced our own protocol (we call it MCP — Model Context Protocol) to define context flow and fallback behavior.

It’s not perfect. Agents hallucinate. Chaining multiple models can fail in weird ways. Debugging LLM logic isn’t always fun. But…

We’re faster. We ship more. Our team spends more time on logic and less on syntax. And the devs? They’re still here — but they’ve become prompt architects, QA strategists, and AI trainers.

We built Linkeme.ai entirely this way — an AI SaaS for generating social media content for SMEs. It would’ve taken us 3 months before. It took 3 weeks.

Happy to share more details if anyone’s curious. AMA.
