数据处理原则

当今的前沿实验物理研究中,数据量越来越大,数据处理的复杂性越来越高。数据处理正在成为实验核心的步骤。黑客精神中对软件工程的原则非常适用于将这一步骤系统化。
“复现”原则
以人类语言和计算机语言的形式,详细记录每一步计算。这是科学的基本精神,与可证伪性一起,是区分科学与伪科学的标志。
“透明”原则
每一步的数据都应尽量可以被人类直接阅读,比如 JSON, CSV。如果不得不用二进制模式,一定是使用最普遍最开放的格式,比如 HDF5。
“一次”原则
Single Point of Truth, Don't Repeat Yourself. 不可在分析做任何重复,任何有意义的信息都应该被共享。
“最佳工具”原则
尽量使用高级语言和语法糖,为每个子任务选择合适的工具。只有在性能分析之后,才在必要时使用低级语言进行性能加速。

Dreams

A Man

I dream to be a true man without procrastination and nice guy syndrome.

I could not become anything: neither bad nor good, neither a scoundrel nor an honest man, neither a hero nor an insect. And now I am eking out my days in my corner, taunting myself with the bitter and entirely useless consolation that an intelligent man cannot seriously become anything; that only a fool can become something.

Smart Guy of Physics

I dream to be a smart guy like Enrico Fermi

Fermi was well-known for his simplicity in solving problems. He began his inquiries with the simplest lines of mathematical reasoning, then later produced complete solutions to the problems he deemed worth pursuing. His abilities as a great scientist, combining theoretical and applied nuclear physics, were acknowledged by all. He influenced many physicists who worked with him, such as Hans Bethe, who spent two semesters working with Fermi in the early 1930s. From the time he was a boy, Fermi meticulously recorded his calculations in notebooks, and later used to solve many new problems that he encountered based on these earlier known problems.

and Richard Feynman

Feynman gained a reputation for taking great care when giving explanations to his students and for assigning himself a moral duty to make the topic accessible. His guiding principle was that if a topic could not be explained in a freshman lecture it was not yet fully understood. Feynman gained great pleasure from coming up with such a "freshman-level" explanation, for example, of the connection between spin and statistics. What he said was that groups of particles with spin 1/2 "repel", whereas groups with integer spin "clump". This was a brilliantly simplified way of demonstrating how Fermi-Dirac statistics and Bose-Einstein statistics evolved as a consequence of studying how fermions and bosons behave under a rotation of 360°. This was also a question he pondered in his more advanced lectures and to which he demonstrated the solution in the 1986 Dirac memorial lecture. In the same lecture he further explained that antiparticles must exist since if particles only had positive energies they would not be restricted to a so-called "light cone". He opposed rote learning or unthinking memorization and other teaching methods that emphasized form over function. He put these opinions into action whenever he could, from a conference on education in Brazil to a State Commission on school textbook selection. Clear thinking and clear presentation were fundamental prerequisites for his attention. It could be perilous even to approach him when unprepared, and he did not forget the fools or pretenders.

Debian Developper

I dream to be a Debian Developper who contributes to the community and fight for the intellectual freedom. The dream came true after 18 years of intimacy with Debian on 2020-09-11.
