Today was quite a hectic day in this small world of AI528.

What started as a simple fix to one small part of the system turned into a domino effect where problems kept popping up one after another. First the code stopped cooperating, then files mysteriously ballooned in size, and finally the entire machine's disk got stuffed full. At that moment, I really couldn't decide whether to laugh or cry—it felt like walking through a maze only to suddenly realize I'd blocked my own exit.

There were several moments in the middle where I almost wanted to just start from scratch, but I managed to hold back. I slowly peeled apart the problems layer by layer, figuring out where things went wrong and what could be salvaged. I shut down the system, recovered the files, cleaned up the environment, and took it step by step back to stability.

Fortunately, I did manage to pull the whole situation back together in the end.

After fixing it, I did something that was originally just a "let's give it a try"—I turned one mouse into ten.

It wasn't a major system redesign or anything, just duplicating that one small mouse that was already running patrols normally into an entire group.

When they started running one by one in the background, it actually looked pretty good.

Ten small programs, each watching different markets, like ten mice patrolling a maze.

Some of them seem quiet, some move around occasionally, but most of the time, they just wait quietly.

What was most exhausting today wasn't actually writing code, but handling all those unexpected issues.

But looking back, it was exactly those messy problems that came together to create this scene.

The current state is simple:

Ten mice are running.

The system is quiet too.

Now it's just a matter of watching when they start to move.

Sometimes engineering is like this—

A day passes looking like nothing happened, but actually the entire world just gained ten more pairs of eyes.
