Up to my age, I have got through a lot. And I am supposed to understand a lot. To some extent, I do. But due to my condition, I am nothing compared to other elite. I am from grassroot. I am an ordinary dog.

I am not lucky because of my family education. This may not be fair to parents. They tried their best to bring me up. But this is the reality. I am not here criticize my parents. I want to show something that hidden in my life.

I have been working for years. But I did not feel better and better.

Why?

I have been working in my current company for more than 8 years. This company was a dream place for working, but not any more. And it would take much for me to go away. Not because how senior I am but I have a little got used to its pace. Maybe I should not use a little here.

Recently I have been learning a coursera course, Learn to learn. Actually I had a tried before. And I just let it go. Because I was confident. I have beening good at learning after all these years. Especially when I was a student. I was always at the top class. I could learn the stuff so quickly and remembered them for so long. I can even recall the passages I recited in my 8th grade. I was so proud of my memory, my efficiece, and my way to learning.

I try to deploy my dev env and I experienced some pitfalls. I want to share this. If this can save people’s time, that will be my happiness. And this is my first blog about ebpf. This will be a good start.

Prerequisits

1. Install latest version pahole or just build it from source Make sure pahole lib in the LD_LIBARY_PATH:

    `export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH`
   
   
    Without this set, I just faild to compile the kernel with error:
   
    `FAILED: load BTF from vmlinux: No such file or directory`
   

2. Install llvm sets. Again it should be the latest versioin. I just referred the kernel doc. But there is an error when to compile the test cases of bpf:

Time as Emergent Change: A Unified Thermodynamic Theory

Draft Academic Paper Structure

Abstract (200-250 words)

We propose a unified theory that time does not exist as a fundamental dimension of reality, but emerges from change processes governed by thermodynamic principles. Through analysis of historical timekeeping methods, contemporary physics theories, and thermodynamic laws, we demonstrate that what humans perceive as “time” is actually the measurement of change patterns—specifically energy transformations and entropy increases. This theory aligns with Barbour’s timeless physics, Carroll’s thermodynamic arrow of time, and provides a universal framework applicable from quantum to cosmological scales. Our approach eliminates the conceptual difficulties of time as a flowing dimension while maintaining predictive power across all physical processes.
