Today I want to talk about a few design ideas in bub that have endured to this day, along with some of my thoughts on interaction between humans and agents.

This post is dedicated to bub, an agent that lives in group chats.

This is a short post about human-agent collaboration in instant messaging, and why we need socialized evaluation more than more benchmarks.

This piece is dedicated to bub, and to my friends.

Hi, I'm PsiACE.

If I had not sprained my ankle on Labor Day in 2021, I might not have walked the path from lakehouse cloud-native to vector multimodal AI native.

In the long process of building software systems that others can rely on, I gradually realized that testing is not merely a QA tool.

A Gambler's City Chronicle This piece is 2021–2025, the years when most overlaps with friends began. 2021 was a database boom, 2024 an AI frenzy.

When I first started working on the Agent Client Protocol Python SDK, it was a small side project born out of curiosity.

Bub's first milestone: automatically fixing type annotations.

Single LLM providers are fragile.

AI agents that execute code are powerful but terrifying.

Programming can be tough.

Last year, I had to leave the database infrastructure field (if you remember some of my previous voices) and dive into RAG application development.

Over the past few weeks, Model Context Protocol (MCP) has sparked significant discussion and attention within the tech community.

This work has been contributed to upstream llama_index as McpToolSpec in the llama-index-tools-mcp package.

This post demonstrates a straightforward approach to using VLMs for parsing unstructured data from images.

Ah, DevRel – the tech world's equivalent of sticking a megaphone in the hands of a mime: everyone sees the gestures, but no one knows what the hell they're trying to say.

Recently, I have been trying to read papers.

Inspired by Databend - set swap to 10G, I checked the swap on my laptop and found only about 8G of zram.

It is called an annual review, but I am only writing a few hurried lines on the first night of 2022, just to leave a marker.

The steps in this article were only verified on Alibaba Cloud, but they should also apply to other cloud service providers.

When using assembly on Linux, NASM or GNU AS is undoubtedly much more convenient.
