MDAnalysis的线性密度模块有bug：模拟一盒Lammps模拟的均匀的水分子，计算出来的线性密度有一些向上突起的尖峰。
There is a bug in the MDAnalysis linear density module：when calculating the linear density of a uniformly simulated box of water molecules using LAMMPS, the result includes some sharp upward spikes.

推荐一个听歌识别曲风的网站：cyanite。
Here I recommend a website for identifying music genres：cyanite.

在coursera上试听了《IBM Data Science Professional Certificate》这一系列，一共有10门数据处理课。

MDAnalysis包是一个用于分析MD的数据结果的python包，其内有丰富的分析工具，包括分析氢键的自相关函数（Hydrogen bond autocorelation function，hbacf）。但是其只支持分析连续的氢键自相关函数（continuous hbacf），不支持分析间断的（intermittent hbacf）。而其内部支持的intermittency参数也不完全符合间断的hbacf的定义。所以，我打算手动修改源代码。
The MDAnalysis package is a Python package for analyzing molecular dynamics (MD) data results, equipped with a rich set of analysis tools, including a function for analyzing Hydrogen bond autocorrelation function (hbacf). However, it only supports the analysis of continuous hbacf and not intermittent hbacf. The intermittency parameter included does not fully comply with the definition of intermittent hbacf either. Therefore, I plan to manually modify the source code.

可以使用ChatGPT做客观的政治倾向分析。因为ChatGPT学习过大量的文本数据，其中自然包括政治方面的知识。事实上，ChatGPT对政治的理解相当深刻，并且十分博学。

Gromacs是一个开源的软件，用c++开发。如果对Gromacs的某个功能不满意，大可以直接去修改其源代码，然后编译，安装。
Gromacs is an open-source software developed in C++. If you are dissatisfied with a particular feature of Gromacs, you can directly modify its source code, then compile and install it.

组里的人要分析一个系统的氢键数量和氢键自相关函数（Hbond autocorrelation function，hbacf）。
A colleague in our group is tasked with analyzing the number of hydrogen bonds and the hydrogen bond autocorrelation function (hbacf) in a system.

约翰霍普金斯大学有新冠期间的确诊人数和死亡人数的数据文件。利用这些文件，可以分析各国的新冠死亡率。
Johns Hopkins University provides data files on confirmed cases and deaths during the COVID-19 pandemic. Using these files, one can analyze the COVID-19 mortality rates of different countries.

写了一个脚本，将Gromacs产生的xvg文件绘制成png图片。
Wrote a script that converts xvg files generated by Gromacs into png images.

推荐一个AI生成歌曲的网站：suno.ai。你提供一些风格提示词，以及歌词。它会据此生成歌曲，生成的质量相当不错。
Here I recommend an AI-powered music creation website：suno.ai. You can provide some style prompts and lyrics, and it will generate songs based on these. The quality of the generated songs is quite good.
