Problem

As a Linuxer, being proficient with the terminal is an essential skill. But in the terminal, downloading and installing things can sometimes be very slow, which is frustrating. I naturally wondered whether I could add a proxy to improve the speed. I had been using Shadowsocks before, and the browser used SwitchyProxy, which achieved basic proxy-based internet access. So, is there a similar tool in the terminal? The answer is yes. Through targeted searching, I successfully solved the proxy problem in the terminal. I summarize it here and hope it can help everyone.

Motivation, Placed First

I used to have a blog on CNBlogs, but I did not maintain it often. Even now, counting everything, it only had three essays and one follower. The main reason was that I did not have the habit of writing. In high school, I kept a diary for a while and wrote more than half a notebook in total. It was all motivational, self-deceiving, content written for myself.

[Abstract] Recently, while working on a C language problem, I needed to split a string. I originally wanted to write it by hand, which would not be too troublesome, but then I thought: other languages all have library functions for splitting strings, so how could C not have one? I searched online, and sure enough, such a function exists and is quite useful. I summarize it here. In the C language manual, it is easy to find the usage of strtok. One thing to note is that, except for the first call, the first argument should be passed… Read more

[Abstract] Recently, while helping senior schoolmates with some projects in the lab, I encountered various timestamps I had never seen before, so I summarize them here. Unix time: everyone is generally familiar with this time, which records the total number of seconds from 00:00:00 on January 1, 1970 to now. This article discusses the relationship between Unix time and various commonly used times, and I share it here. Windows NT time: the 18-digit Ac… Read more

This summer, I was fortunate to participate in the UK exchange camp jointly organized by Beihang’s Advanced Engineering School and the Cambridge Eastern Education and Development Society. The exchange camp lasted two weeks, with rich content and diverse formats. It gave me a deep understanding of British humanities and culture, as well as the situation of Chinese students studying abroad, and successfully fulfilled my pre-trip goals. Next, I will organize the whole trip and share it with everyone, hoping it will be helpful.

There is only a month and a half left before I leave Shahe, this “broken” place. Unexpectedly, I have already stayed here for almost two years, so now is the most suitable time to write my Shahe-Beihang story.

Looking back, I have gone from fresh meat to old cured meat. The initial freshness I felt toward college life has long disappeared, turning into day after day of busyness with coursework. Sometimes I really want to change my state and live the college life I once imagined. But when facing the larger system, I feel my own smallness and helplessness, and can only comfort myself with “for the interests of the country and the nation.” Here I do not want to complain too much. I only want to share my two years of experience at Shahe-Beihang, to give later students a reference and leave myself a log for future review.

June 7, 2013 was the last day of the Gaokao for the senior students one grade above me in high school.
From that day on, I was the one closest to the Gaokao, although I would not officially enter senior year until September.
At the time, I was studying at Xiangfen High School in Shanxi Province. I was not yet 17, and I wrote this “My Dream” to state my ambition and encourage myself. Now ten years have passed. In June 2023, while organizing files on my hard drive, I was pleasantly surprised to discover this “document.” Looking back, I did not realize my Tsinghua dream back then. After being beaten by society, my ideals, including my literary talent, are far from as excellent as they were then. But the words from that year still move me. I thank my former self.
I was once a young man.

Main Text Begins

At fifteen, Confucius set his heart upon learning, thus establishing the life ideal he would pursue for the next several decades without wavering. Although I am not a sage, only an ordinary middle school student, I also have my own life ideal: that the world changes because of me. When later generations hear my name, they will raise their thumbs and offer sincere praise, just as I do now when I hear the names of great people like Einstein.
