siyuan
A privacy-first, self-hosted, fully open source personal knowledge management software, written in typescript and golang.
Project mention: SiYuan, Privacy First, Affero GPL, self-hosted PKMS written in ts and go | news.ycombinator.com | 2025-05-18I came across this project a while back and adopted it for my personal Personal Knowledge Management System/PKMS.
I've bounced around a few PKMS in the past, eventually settling on Obsidian but later moving to Logseq in an effort to avoid relying on closed source tooling. Then recently I discovered this project and I've been beyond impressed.
The desktop and mobile apps work very well and to be entirely honest are way more polished than I've come to expect from a FOSS PKMS, it's full featured with more or less everything I could want. It has a built in git-like VCS, it has integrated rendering for Mermaid, Plantuml, etc, and what I've personally found most interesting is it supports representing your notes as structured data that you can query with SQL.
My one gripe is the english docs are pretty sparse but otherwise I've had a phenominal time with SiYuan and I thought HN might find it interesting.

Currently editing in Cursor, using agents heavily as I'm a solo dev with limited time. Been exploring running models locally and looking into Zed & Void (https://voideditor.com/). Anyone have opinions on these? Downloading both to try but wondering if the free plan on Zed is doable for full time software engineering, mostly working on next.js sites & native mobile apps in Swift/Kotlin

📦 Repomix is a powerful tool that packs your entire repository into a single, AI-friendly file. Perfect for when you need to feed your codebase to Large Language Models (LLMs) or other AI tools like Claude, ChatGPT, DeepSeek, Perplexity, Gemini, Gemma, Llama, Grok, and more.
I created a script to pack it into a markdown file. Later I found this which does a better job, so I use it now.

Here's the thing. I want a personalized AI. Full stop.
There's no arguing back and forth.
Tech is here someone needs to put it together.
I'm so busy with other things, but I really want to see this thing come through and happy to work on it.
To me, its insane Apple didn't figure it out.
The goal: Build a truly personalized AI.
- Single threaded conversation with an index about everything.
- Bot should be accessible via WhatsApp, Insta, Email, or a phone call through an app (WebRTC connection).
(https://botpress.com/ is a really good starting point).
- Operator at the back that has login access to almost all tools I use, but critical actions must have HITL.
- Bot should be accessible via a call on the app or Apple Watch.
https://sesame.com/ type model and this is very doable with https://docs.pipecat.ai especially their new release that allows for long running function calls.
Speech detection (VAD) is still a problem, but I think its more of systems engineering problem than ML problem. Interruptions need to feel smooth.
But this is not a blocker. What exists is good enough.
- It can should be able to digest images, voice notes, etc.
- everything should fall into a single personal index (vector db).
One of the things could be, sharing 4 amazon links of some books I want to read and sending those links over WhatsApp to this agent.
It finds the PDFs for the books from https://libgen.is and indexes it.
I phone call the AI and I can have an intelligent conversation about the subject matter with my AI about the topic.
I do this a lot with xAI's Grok and its a surprisingly effective tool.
I give zero fucks about issues like piracy at the moment.
I want to later add more capable agents as tools to this AI.

langfuse
🪢 Open source LLM engineering platform: LLM Observability, metrics, evals, prompt management, playground, datasets. Integrates with OpenTelemetry, Langchain, OpenAI SDK, LiteLLM, and more. 🍊YC W23
I have been spending a lot of time exploring AI Coding Assistants like Amazon Q Developer to see how they can help open source developers, and Ricardo Tasso came up with a great example in how he is using Q Developer to generate deployment configurations for Kubernetes. He has written this up in his post, Creating Deployment Configurations for EKS with Amazon Q so go check it out (you can get started with Amazon Q Developer for free by registering your Builder ID here). Langfuse is an open source LLM engineering platform that helps teams collaboratively develop, monitor, evaluate, and debug AI applications. AWS Community Builder Matsuda shows you how you can deploy this, using CDK to make it simple. If this sounds like something you are interested in, go read the post Self-Hosting Langfuse v3 on AWS Using CDK.
