·4 views

Want a WhatsApp chatbot without going through Meta's business verification, template approvals, and per-conversation pricing? Combine n8n (the open-source workflow automation tool) with WaSphere — an open-source (MIT), self-hosted WhatsApp API — and you get a fully self-hosted chatbot stack on your own server. WaSphere connects to WhatsApp (scan a QR code once) and exposes a local REST API plus HMAC-signed webhooks. n8n receives inbound messages via a Webhook trigger, runs your bot logic, and calls WaSphere's API to send replies.

When do AI agents actually matter? Benchmarking RAG vs GraphRAG vs Agentic GraphRAG on TigerGraph

Everyone's building agents right now. But a better question than "can an agent do this?" is "when does an agent actually beat something simpler?" For the TigerGraph Agentic GraphRAG Hackathon, I built three question-answering pipelines side by side to find out. The dataset was ~2,900 Wikipedia articles about Olympic events, plus 100 evaluation questions with answers and 50 hidden ones.

Driftnet: one box that catches everything I would otherwise forget

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend I built Driftnet for my friend Samuel. Before I wrote any code I asked him one question: what is actually going wrong for you? Samuel is always busy and always building something, and ideas, links and opportunities reach him from everywhere. He did not give me a feature list. He told me a story.

I built a private offline journaling tool for my group of friends. Powered by Local Gemma

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend My friends and I are trying to spend less time mindlessly scrolling through social media. We noticed how easily scrolling can become a way to avoid sitting with our feelings, so we encourage each other to write about what we are experiencing. But writing by hand does not work for everyone. Some friends told me they often turn to ChatGPT to vent about their feelings. I wanted to give them a digital place to journal, with a little help when they cannot find the words or untangle a feeling on their own.
