## One-liner

Sunday was the department team building, Saturday was the company annual gala, and Friday was the IPO day.

Yeah, the whole weekend was taken.

Since this is the fourth week of writing the report, the things I can really recall are probably the important ones.

## What I did

- **Work**
  - [ ] <What did I move forward? (project/collaboration/delivery)>
    - [ ] No extra notable progress in project collaboration/communication.
  - [ ] <What problem did I solve? (context/action/result)>
    - [x] Fixed an internal system Excel template import issue. The interesting part was borrowing the NetBox template import approach and making the system easy to use during design.
  - [ ] <One blocker/risk and my plan>
    - [ ] **The incident handoff system is still risky overall. I need to map out every logic step clearly.**
  - [ ] <Chore: company odds and ends>
    The company annual gala happened this week. Congrats on the IPO, and I hope the company keeps growing. Hope my boss is doing well, and the team too.

    Night view of the World Reception Hall by the Huangpu River. Neon everywhere.

- **Tech**
  - [ ] <What did I learn? (concept/tool/source/paper)>
    **A bit embarrassing — I did not read any of the papers I planned. I will do it in week four.**
  - [ ] <What did I build/fix? (PR/refactor/debug/perf/automation)>
    Not really.
  - [ ] <One reusable takeaway in a single sentence>
    When designing systems, reference well-known open-source projects more.

- **Life**
  - [ ] <Health: training/diet/sleep — what mattered most?>
    This was the first week after New Year, but technically the second week of 2026.

    Played badminton once on Friday.
  - [ ] <Social/family: one high-quality interaction>
    I was too involved in company work and lacked high-quality time with family.
  - [ ] <Fun: one moment that recharged me>
    This was the final week of Honor of Kings Season 40. On the last night I earned the top marksman title — my first time getting it. Worth celebrating. 🎉

- **Thinking**
  - [ ] <One recurring question>
    The recurring question is how to understand the new era "kernel": the relationships between vLLM, LLMs, and AI models, and their relationships with the world and reality. I am hungry to learn.
  - [ ] <One belief I strengthened (and why)>
    The big boss (OI) keeps saying we should try long-term holding. OK, then I will try buying some company stock.
  - [ ] <One decision: what I will change next week>
    Exercise more.
