A 20-Year Linux Veteran’s Obsession: Why I Built an "OS-Style" AI Agent System with One-Click Rollback

I’ve spent the last 20 years living and breathing open source, contributing to the Linux ecosystem and serving as a core creator of Linux deepin. If those decades have taught me anything, it’s this: the success of any system isn't in its flashy UI—it’s in the "plumbing." Lately, I’ve been diving deep into the AI Agent space. While frameworks like OpenClaw and Hermes are brilliant, I found myself f...

Why I built a local terminal workspace instead of using tmux

Why I built a local terminal workspace instead of using tmux

I wanted a terminal workspace that behaves more like a normal desktop app. Something that: keeps tabs and splits restores layout and working directories after restart uses normal Ctrl+C / Ctrl+V with the system clipboard I tried tmux for a while and realized it solves a different problem. It’s great for remote sessions, long-lived processes, and connection resilience. But my workflow is st...

How I Built an MCP Server for Media & Entertainment Intelligence

Give your AI agent real-time knowledge about Netflix, Disney, and 30+ media companies. If you work in media and entertainment — or invest in it — you know the information landscape is brutal. Earnings calls, streaming data, box office reports, executive moves, regulatory shifts. It's scattered across Variety, Deadline, THR, SEC filings, and a dozen other sources. I built Studio Signal to solve t...

Subqueries vs CTEs in SQL: A Practical Guide for Data Analysts

💡 How I Finally Understood Subqueries vs CTEs When I first started learning SQL, I remember feeling confident—until I ran into subqueries. At first, they seemed simple. “Just a query inside another query,” I told myself. But the moment I started working with more complex datasets, my queries became harder to read, harder to debug, and honestly… frustrating. Then I discovered CTEs. I ...

Cache-Aside and the Null Sentinel Pattern

There is a class of bugs that are worse than crashes. Crashes are loud, they page someone and they get fixed. This one is quiet. Your cache is running, your hit rate looks fine. But your database is being hit on every single request for data that has not changed at all. I hit this while implementing cache-aside in a side project. A Quick Recap of How Cache-Aside Works Before getting i...

Stop Manually Fixing Your Agent’s Output: How We Built a Custom Skill for Monday.com

I'm using my AI agent to create Monday.com tasks. I ask Claude Code to create a task with a proper description, and it does - except when I open the task, the description field is empty. The text I wanted is sitting in the updates thread. Like a comment. Not a description. The reason I'm doing this from Claude Code at all: context. When you're mid-task - debugging something, writing a spec, revie...
