关于About
比起一串固定标签，我更愿意用“我长期在做什么”来介绍自己。
I would rather introduce myself by what I keep doing than by a fixed list of titles.
我是郝春霖。做科研，也做一些有趣的东西；写技术文章、记笔记，也记录自己的思考。
I’m Chunlin Hao. I do research, build things I find interesting, write technical articles, keep notes, and record my thoughts.
我做原子力显微镜相关科研，也喜欢自己做工具和网站。比起把个人主页做成一份静态简历，我更想让它成为一个能跟着我一起长大的地方：研究、项目、笔记、写作，以及对科技和生活的长期观察，都可以慢慢留在这里。
I work on atomic force microscopy and also like building tools and websites. Rather than a frozen résumé, I want this to be a place that can grow with me — research, projects, notes, writing, and long-term observations about technology and life.
SomeUseful
SomeUseful 对我来说不只是一个“网站项目”。它更接近我长期做事方式的缩影：从大量信息里筛出真正有用的东西，再把它整理得更清楚、更容易被别人使用。
SomeUseful is more than a website project to me. It reflects how I like to work: filter large amounts of information down to what is genuinely useful, then make it clearer and easier to use.

我关心的不只是“拍出一张图”，而是图里的信号到底意味着什么、哪些是样品性质、哪些可能来自测量过程本身。
I care not only about producing an image, but about what the signal actually means — what belongs to the sample and what may come from the measurement process.
把值得留下的东西慢慢写下来Keeping what feels worth remembering
我喜欢技术写作，也喜欢记笔记、写随笔和故事。它们不一定都需要立刻成为“作品”，但值得在个人网站里有自己的位置。
I enjoy technical writing, notes, essays and stories. Not all of them need to become finished “works” immediately, but they deserve a place here.
在知乎、小红书和 Bilibili，我使用「字符序列」这个名字。
On Zhihu, Xiaohongshu and Bilibili, I use the name “字符序列”.
