[AI-translated] Tonight I finished watching 3Blue1Brown's video “There Has Never Been a Better Time to Devote Yourself to Mathematics,” and it stirred up some feelings that I record briefly here.

[AI-translated] Picking up where the previous post left off, this one focuses on why we no longer use www today, and on how we actually handle it now.

[AI-translated] I always assumed the www in the address bar was just something the browser hid from us. The more I looked into it, the more I found that it connects to the division of services on the early Internet, the constraints of DNS, and the way websites are deployed today.

[AI-translated] A chance update notice from a hand-tracking library gave me the idea, and a day and a half later I had a simple rhythm game demo.

[AI-translated] A record of how the RSS feed on my personal site evolved: working, beautified, suddenly broken, and finally fixed.

[AI-translated] I have never been bullish on humanoid robots becoming the next generation of general-purpose productivity. I want to put my current judgment on the record: if I end up being proven wrong, I will at least be able to look back and see exactly which of my concerns the industry managed to overcome.

[AI-translated] While reviewing data structures, I realized I keep choosing the wrong way to implement a queue, so I built a decision tree to lay out the factors involved and summarize them.

[AI-translated] While preparing in Wuhan for a second attempt at the postgraduate entrance examination, I took a day off on the weekend, followed a local creator's route around the city, visited the Hubei Provincial Museum at last, and ate plenty of good food.

[AI-translated] TCP slow start is often simplified as “the congestion window doubles every RTT,” but textbooks, RFCs, and the Linux kernel describe the same mechanism from different layers. I compare the three views to clarify whether cwnd grows by ACKs, bytes, or complete segments.

[AI-translated] Does localhost really pass through the network protocol stack when we use it during development? How many layers of the network are involved?

[AI-translated] As I left university, I wanted to record both my memories of those four years and how my choices gradually taught me not to treat grades, rankings, and a résumé as life's only objectives.

[AI-translated] With only a few days left before graduation, I was reluctant to leave Xiamen, so a classmate and I visited several interesting eateries around the city—some delightful, others disappointing.

[AI-translated] For anyone who wants to know what a computer science and technology major actually studies: it is not just writing code, and not just fixing computers, but a whole course of training built around computation, systems, software, and engineering practice.

Although the idea of writing blogs already feels a little outdated, I still recommend it. It helps you clarify your thoughts, record the process of growing up, and maybe even meet like-minded people along the way.

[AI-translated] A running record of the browser extensions I use and the other small web tools I recommend.

After finishing the story of Death Stranding 2, I began to understand MEME as a way for the genes of human culture to keep growing. AI can reuse these cultural genes, but new cultural genes may still have to grow out of human experience.

From a student innovation project and a medical management system to reproducing and improving a pelvic fracture CT segmentation algorithm, this post records my graduation project and how I slowly learned to find the real problem inside failure.

[AI-translated] I have always had a habit of collecting interesting sources of information, so I wanted to write down the few that I remember as high quality, frequently updated, and genuinely fun to read—for my future self, and to share with everyone else.

My old terminal was packed with oh-my-zsh and plugins I could barely remember, and it looked ugly enough that I did not even want to use it. So I decided to rebuild my terminal from scratch.

I recently found a GitHub project called voice-input-src, a voice input app for Mac. The surprising part is that the repository contains only one detailed prompt for AI.

This is the literal first blog post on my personal site, sharing my thoughts and experiences.

This is my travel note in Guangzhou. (translated by ai)

[AI-translated] I happened to find the travel diary I wrote after visiting Xi'an. It is still a simple day-by-day record, but it brings the trip back to me, so I am publishing it here before finding it by accident all over again.

This is my travel note in Chaoshan. Tracked my first experience of travelling by myself. (translated by ai)
