The PostgreSQL Server Info panel in DataCollie is ready too! It's a v1, so features are a bit lean, but it covers all the essential metrics. #PostgreSQL #BuildInPublic

PostgreSQL's privilege management is much more complex than MySQL's. Still, I'm making a little progress every day. #DataCollie #BuildInPublic #JavaFX

Built a MySQL server status dashboard from the limited metadata available. #DataCollie #MySQL

Max Xiong • DataCollie @maxiong.bsky.social · 26/09/2026

Spent the past few days building user and privilege management for MySQL in DataCollie. It’s a surprisingly complex module, with many layers of inheritance. MySQL 8 adds even more moving parts: dynamic privileges, role-based access control, and privilege inheritance. #buildinpublic #mysql

Max Xiong • DataCollie @maxiong.bsky.social · 24/09/2026

Designing new DBA modules to make database management less of a chore. What’s missing in your current stack?

Max Xiong • DataCollie @maxiong.bsky.social · 13/09/2026

I’m working to make DataCollie ’s ER diagram experience the best in its class — both in capability and in how it feels to use. #BuildInPublic #JavaFX

Max Xiong • DataCollie @maxiong.bsky.social · 12/09/2026

I’ve been working on ER diagrams for DataCollie, and it’s making real progress. #JavaFX #BuildInPublic #Database

Max Xiong • DataCollie @maxiong.bsky.social · 02/09/2026

Finished the last two pieces of DataCollie’s SQLite support today: Query Console integration and Stella, my Data Agent. Both are now done. DataCollie has reached another milestone. 🚀 #DataCollie #SQLite #AI #BuildInPublic

Max Xiong • DataCollie @maxiong.bsky.social · 01/09/2026

Spent tonight wrapping up DataCollie’s SQLite support, filling in the last pieces for table design: CHECK constraints and triggers. SQLite support is almost done. 🚀 #DataCollie #SQLite #BuildInPublic #JavaFX

130

Max Xiong • DataCollie @maxiong.bsky.social · 31/08/2026

Tonight, I finished DataCollie’s SQLite index metadata support and management features. One step closer to completing SQLite support. 🚀 #JavaFX #SQLite #BuildInPublic

Max Xiong • DataCollie @maxiong.bsky.social · 30/08/2026

Working on SQLite support for DataCollie. About 80% of the compatibility work is done, and I’m still pushing forward. 🚀 #DataCollie #SQLite #BuildInPublic

140

Max Xiong • DataCollie @maxiong.bsky.social · 26/08/2026

DataCollie’s PostgreSQL support is basically done. Tomorrow, I’ll start working on SQLite support.

110

Max Xiong • DataCollie @maxiong.bsky.social · 16/08/2026

Meanwhile, MySQL’s native routine debugging capability is basically zero, unless you build your own SQL-level instrumentation. @DataCollie will define a unified debugger abstraction and interaction protocol, making it easier to implement Routine Debugging consistently across different databases.

020

Max Xiong • DataCollie @maxiong.bsky.social · 16/08/2026

Tonight, I was impressed once again by #PostgreSQL, a database that truly represents advanced engineering. Its `pldbgapi` extension provides a complete debugging API for Functions and Procedures: breakpoints, Step Into, Step Over, Continue, variable inspection — everything you’d expect.

Max Xiong • DataCollie @maxiong.bsky.social · 16/08/2026

Recently, I completed DataCollie’s PostgreSQL compatibility work. DataCollie now supports both MySQL and PostgreSQL as relational databases. But this is only the beginning.

120

Max Xiong • DataCollie @maxiong.bsky.social · 03/08/2026

DataCollie has officially begun its PostgreSQL integration.

120

Max Xiong • DataCollie @maxiong.bsky.social · 01/08/2026

Implemented a new feature in Stella Agent that lets users manually add executed SQL code blocks to the Query Console whenever needed. #DataCollie #JavaFX

110

Max Xiong • DataCollie @maxiong.bsky.social · 28/07/2026

When designing permissions for an AI agent, we should follow two principles: 1. Strategically, make sure the agent does the right things. 2. Tactically, stop it from doing the wrong things. These two principles correspond to two different layers of permission control. #DataCollie #JavaFX

110

Max Xiong • DataCollie @maxiong.bsky.social · 26/07/2026

And the ability to harness AI is itself an engineering skill that must be continuously refined. Craftsmanship still matters in the AI era. Without it, we’ll only end up producing pile after pile of electronic junk.

Max Xiong • DataCollie @maxiong.bsky.social · 26/07/2026

AI is a racehorse, not a guide. It needs direction, reins, and someone who knows how to handle it.

100

Max Xiong • DataCollie @maxiong.bsky.social · 26/07/2026

Most of my work over the past few days has been about making sure users know what the agent is thinking, where it is, and what it is doing—while giving them clear ways to set boundaries, interrupt it, and steer it in a different direction.

110

Max Xiong • DataCollie @maxiong.bsky.social · 26/07/2026

Real-world lessons from building AI agents: My biggest concern isn’t that they aren’t smart enough. It’s that I constantly have to find ways to rein them in and deliberately make them “less smart” before they run too far in the wrong direction.

440

Max Xiong • DataCollie @maxiong.bsky.social · 25/07/2026

I also exposed DataCollie’s data access capabilities to the Agent as internal tools, seamlessly integrating Stella Agent into DataCollie as a truly native part of the product.

010

Max Xiong • DataCollie @maxiong.bsky.social · 25/07/2026

Today, I implemented UI-based conversation context selection and the corresponding backend logic for #DataCollie ’s built-in Stella Agent. #BuildInPublic #JavaFX

250

Max Xiong • DataCollie @maxiong.bsky.social · 23/07/2026

#DataCollie 日々一歩ずつ。今夜実装したのはひとつだけ。AI Chat Pane が、最も安定かつ軽量な方法で Markdown の表データを認識し、レンダリングできるようになりました。明日はもう金曜日。うれしい。この週末はフルスロットルで、Stella Agent の Tool Call に対する手動承認機能を実装する予定です。 MySQL の対応が終わったら、できるだけ早く他のデータベースにも対応しようと思っていました。ですが、よく考えた結果、まずは Agent の開発を優先することにしました。 #BuildInPublic #JavaFX

Max Xiong • DataCollie @maxiong.bsky.social · 22/07/2026

My local MySQL instance has no password, and she somehow found and used the MySQL client to complete the task. Damn, this is getting out of hand. I need to put her on a leash and make sure she only works within the boundaries and workflows I define.

000

Max Xiong • DataCollie @maxiong.bsky.social · 22/07/2026

#DataCollie’s built-in Stella Agent is running wild on my computer like a horse with no reins. I only gave her the ability to execute shell commands, then casually asked her to do something. What she did went far beyond my expectations.

210

Max Xiong • DataCollie @maxiong.bsky.social · 21/07/2026

My Stella Agent can finally do more than just chat—it can actually get things done. I’ve completed Tool Call support in OpenAI API-compatible mode, allowing Stella to autonomously execute commands based on its reasoning.

120

Max Xiong • DataCollie @maxiong.bsky.social · 20/07/2026

#DataCollie — one small step every day. Spent two hours pixel-polishing the UI for selecting Stella Agent’s Tool Call permission mode in DataCollie. Pretty happy with it now. Calling it a day. #BuildInPublic

170

Max Xiong • DataCollie @maxiong.bsky.social · 19/07/2026

Today I added ChatGPT support to my Agent and discovered something interesting: ChatGPT Plus doesn't include API access. Plus works for ChatGPT, the apps, and OpenAI products like Codex. Third-party apps still need a separate API key, with separate pay-as-you-go billing.

010

Max Xiong • DataCollie @maxiong.bsky.social · 18/07/2026

#DataCollie Day by Day Tonight I completed another major refactor of connection state synchronization, connection switching, active database switching, and the execution flow.

010

Max Xiong • DataCollie @maxiong.bsky.social · 18/07/2026

Dear MySQL, It's 2026. We have AI agents writing SQL. But I still can't: Rename a Procedure Rename a Function Alter a Procedure body Alter a Function body Every edit is still: DROP -> CREATE Sincerely, Every database tool developer.

120

Max Xiong • DataCollie @maxiong.bsky.social · 17/07/2026

Implemented MySQL Event management of DataCollie tonight. #JavaFX #BuildInPublic

140

Max Xiong • DataCollie @maxiong.bsky.social · 15/07/2026

Vector databases, here I come. Qdrant will be the first one supported by #DataCollie. The moment I saw its dashboard, I smiled—so much room for improvement. 😄 Milvus was originally first, but after a closer look... not my style. Sorry, Milvus. You’ll have to wait.

110

Max Xiong • DataCollie @maxiong.bsky.social · 12/07/2026

This weekend, I implemented Project Management mode and added support for managing Query File scripts. With the project-based architecture in place, future feature expansion will be much easier. #DataCollie #BuildInPublic

280

Max Xiong • DataCollie @maxiong.bsky.social · 09/07/2026

Implemented flexible multi-level grouping for Connection nodes in the data object navigation tree. #BuildInPublic #DataCollie #JavaFX

150

Max Xiong • DataCollie @maxiong.bsky.social · 03/07/2026

Tonight I added a new context menu item to the Table node in the navigation tree: “Query Data in Console.” A little progress every day. #BuildInPublic #DataCollie #JavaFX

170

Max Xiong • DataCollie @maxiong.bsky.social · 30/06/2026

Continuing to polish the creation and execution flow for MySQL Procedures and Functions. #DataCollie #BuildInPublic #JavaFX

170

Max Xiong • DataCollie @maxiong.bsky.social · 29/06/2026

Spent the past few days working on the Procedure / Function editor and executor. DataCollie keeps moving forward, one piece at a time. #BuildInPublic #DataCollie #JavaFX

160

Max Xiong • DataCollie @maxiong.bsky.social · 20/06/2026

#DataCollie day by day I reworked the main layout and moved the execution log output from the Query Console tab to the top-level layout. This makes it easier to capture logs from all kinds of operations, instead of limiting them to a single Query Console. #BuildInPublic #JavaFX

Max Xiong • DataCollie @maxiong.bsky.social · 13/06/2026

In 2000, Linus said: “Talk is cheap. Show me the code.” That line shaped a generation of programmers. In 2026, Max Xiong says: “Code is cheap. Show me the product.” The real test is whether you can turn code into a product, ship it to real users, and make them willing to pay for it.

120

Max Xiong • DataCollie @maxiong.bsky.social · 12/06/2026

#DataCollie day by day Tonight I made some tweaks to the “New MySQL Connection” window. Really happy with how it looks now. JavaFX CSS gives me the freedom to shape the UI exactly the way I want. #BuildInPublic #DataCollie #JavaFX

Anthropic calling for a global pause on frontier AI is interesting. My simple read: you got to the table first, now you want to raise the entry barrier? AI safety matters. But if “safety” means closed-source giants move forward while open-source builders pause, that’s comedy.

140

Max Xiong • DataCollie @maxiong.bsky.social · 05/06/2026

Implemented a cross-platform custom title bar for Mac and Windows. The UI just got a little more polished. #BuildInPublic #DataCollie

Max Xiong • DataCollie @maxiong.bsky.social · 31/05/2026

Spent today polishing the #DataCollie's AI Chat Pane with some tiny pixel-level refinements. #buildinpublic #JavaFX
