Do not get gentle into your CS major

I used to believe I was the one on earth who loved this field the most. Now I suspect I care the least. I cannot see the future, sprinting toward a horizon that keeps receding into darkness. Part of this text was written one year ago, originally meant to be the script for a video. I found it too clumsy and in constant need of revision, so I reformed it into an essay.

Before I begin, let me summarize a remark of one brilliant peer. Variance is enormous in the field. Joining the frontier requires a résumé that is outlandishly perfect. It is never too much to repeat this. However, since anyone actually aiming for that perfection is unlikely to read a post like this, I only deal with the question how large the the gap/residual will be if you fall short.

‘My Path’ after twenty years

Goliath was pelted with ten million stones every June. It must be painful.
— Me, commenting elsewhere

After the faith fades, the ritual remains.
We still carry stones — not for victory,
but to remember our past goals.
— ChatGPT, mimicking a contemporary

Twenty-two years ago, a college fresher penned an essay titled My Path. She began with a modest line: 'I don't consider myself a winner. I am just an ordinary person who keeps growing and thinking.'

My linguistic history

Before the FSF40 gathering, William Goodspeed checked my blog when receiving my inquiry email. When I opened the same website in person, he asked: 'Are you into linguistics?' I wasn't sure what expectations an English major might have by 'into linguistics', so I awkwardly avoided answering.

The other day, I read a reflection on their linguistic journey from a linguistics guru. This guru's encounter with language began with academic competitions and has since woven a marvelous double helix of career and language, an achievement I can hardly imagine. Their article, however, debunked my 'single-origin hypothesis of the linguistics community', as I had assumed the entire language circle stemmed from discussions on a BBS forum in the early 2000s. This prompted me to reflect on the role language and linguistics have played in my life.

A slice of Bash programmable completion

During the process of migrating a Conda environment and mitigating confliction, I noticed Bash programmable completion was experiencing an issue when the environment was not yet incomplete. I seemingly showed no curiousity, proceeding to enter the command despite STDERR for the rest of migration. This post was created after that since there are no Marginalia search engine-style sources on Bash programmable completion.…

Enhypen Alphabet

Enhypen Alphabet is a language-neutral spelling system for Chinese characters, specifically for Chinese-derived proper names. It bears less prejudice from Mandarin, as compared to Yuen Ren Chao’s General Chinese and Professor Gu Qian’s Common Sound Systems of Chinese Dialects, where the bias is more or less dedicated.

It serves as a startpoint to ‘Sinicize’ respective for tacit perceptions of characters, which is barely possible for natural languages, stubborn for previous works, and Shidinn leads to the other extreme.

Richard Stallman 不想改变世界。他不想和风车战斗。他不想再造轮子。Richard Stallman 只想寻回他的朋友，他的社群。

这个蓄须的胖乎乎的年轻人，社交关系一直不简单。他总是沈浸在书里，爱解逻辑谜题，总是找不到自己的位置。他喜欢与人交往、长谈和跳舞，可他对数学的兴趣似乎总有些格格不入，尤其是他的幽默常被误解，使人惊愕或害怕。…

‘If need be, I will leave w/o looking back…’

You may have perceived the title as another clickbait, and the post as a mere '2024 review'. The title is the exact word I repeatedly told myself, however, ever since the outcome of my incorrigible decisions this year. I will remember the train returning to Lanzhou, where I stared at the dim wooden bulkhead, sitting huddled and feeling as if fevered. Following the should-have-been-memorable graduation, I viewed no exhibition, applied for no internship, and pushed further no personal projects that is even less viable in the new circumstances.

This should not hinder that the title line is an excuse. I have been giving up giving up all the time. I am conned to believe that I am not facing a choice. Dare call it no choice; that escape to Zion is the only choice.
