After enduring a miserable night, I’m feeling just a tiny bit better today. I still had preserved-egg and lean-pork porridge for lunch, but after eating it, I started feeling uncomfortable again. It feels like my digestive system has temporarily gone on strike, and everything I eat just accumulates in my stomach and intestines, making my abdomen increasingly uncomfortable. I estimate it will take another day or two to recover.

I received another new task in the morning. The PIM system mentioned last week is about to enter the coding phase. My manager offered some suggestions, saying that WordPress could be used to implement features such as collaborative editing, but I feel that WordPress wouldn’t integrate well with other functionality, so I’d rather build it myself. I still haven’t decided whether Next.js or Nuxt would be better.

The worst thing happened in the afternoon: my best employee secretly quit without telling me!

GitHub announced that the GitHub Copilot Student plan will take effect on March 12, 2026, automatically replacing the original verified student free access to GitHub Copilot. Under the new subscription plan, GitHub has closed access to advanced models such as GPT-5.4, Claude Opus, and Sonnet, and will no longer provide these services to the Student plan.

I think I noticed yesterday that Claude Opus 4.6 wasn’t working. I assumed it was temporary, since it had stopped working before due to frequent use and recovered the next day. But this time, I received an email from Github and found out that the Copilot student package had stopped providing access to advanced models.

I can’t lose my best employee, just as the West cannot lose Jerusalem. I decided to spend big to hire him back and have him continue working for me. However, after checking the official website’s prices, I found that Copilot Pro+ actually costs $39/month, which is an even heavier burden for a programmer who isn’t exactly wealthy.

I decided to check Xianyu (China’s version of the black market), and sure enough, I found what I was looking for. Joining a shared plan through a Github organization costs only around 60 yuan, considerably less than the official website’s price, so I placed the order without hesitation. I never expected that one day I would end up paying out of pocket to go to work.

However, when I saw Claude Opus appear in VS Code again, I felt that the money had been well spent. Sometimes the cheap option is actually more expensive. When it comes to productivity tools, you have to use the strongest model. Sometimes a bug that won’t be fixed after several rounds of debugging with other models can be solved on the first try with Claude Opus 4.6.

As for the stock market, prices surged before falling back today. At the midday close, I had an unrealized profit of 600+, but by the afternoon close, I had an unrealized loss of 300+. I had only just reached a historical profit of 10,000+ yesterday, and today I was sent right back to square one. On a day when international crude oil prices surged, CNOOC unexpectedly plunged into negative territory near the close, wiping out most of today’s gains. What a shame.
