What do you do?
I'm a programmer by trade. I write code, and I write articles.
Why xusansi?
It's a homophone for xu sansi — "need to think thrice." A reminder to think before I act.
What do you write about?
Technology, product work, and ideas from work and everyday life.
Your articles use a dialogue format. Are these real conversations?
They're pseudo-dialogues. The person asking could be a friend, myself, or AI.
You say "concrete, no filler." How do you pull that off?
The dialogue format helps. When you're talking to someone, you can't ramble. It forces me to be direct and to the point.
How do you decide whether to publish something?
I ask: is the question worth asking? If the question has value, the article is worth publishing.
Why not make videos?
Video production is too time-consuming. Even with AI help, it's a lot of work, and my free time is limited.
