In the age of LLMs, what is the point of learning programming languages?

I think there is still a reason to learn programming languages even when LLMs can write a lot of code: it gives you the foundational knowledge needed to have better discussions with an LLM, evaluate its output, and ask better questions.

But honestly, that doesn’t make it very motivating to study syntax and language details. Does anyone else feel this way? What keeps you motivated to learn programming deeply instead of relying on LLMs?

I had been considering majoring in computer science, but lately I’ve started wondering whether it still makes sense and am thinking about choosing a different major. I’m curious how people already working or studying in the field see this.

I just started learning Rust, but &, !, str, and String are melting my brain

I’ve just started learning Rust, and I keep getting lost in all the little distinctions: when to use `&` and when not to, why some things end in `!`, `str` vs `String`, and so on.

I understand these probably fit together once ownership and borrowing click, but right now it feels like too many separate rules at once. Is there a clear beginner-friendly cheat sheet or visual summary that explains the common symbols and core types together?

I let Opus 5 loose in Blender and asked it to render a wizard. This is what I got.

Not quite the wizard I had in mind, but honestly… I kind of love it.

A remote MCP for Japanese LuaLaTeX notes and handouts

I built TeX64 to give Claude and Codex the styles, scaffolds and checks needed to create Japanese lecture notes, exam summaries and reports locally. After connecting it, you can describe what you want in plain language and let the client handle the files, compilation and visual checks.

The server is read-only and stateless; it doesn't receive or store the document itself.

Claude Code:

claude mcp add --transport http tex64 https://mcp.tex64.com

Codex:

codex mcp add tex64 --url https://mcp.tex64.com

GitHub: https://github.com/Fermion-company/texmcp

It's Japanese-first and fairly opinionated. Feedback on the tool split or document types would be useful.

I made a small macOS app for typing LaTeX next to the cursor

I got tired of switching windows just to type a formula, so I built MathHover. Hit a shortcut, type with a live preview, press Enter, and it pastes the LaTeX back into the app you were using.

It is free, runs locally, and does not need an account or AI. macOS for now.

Would this fit your workflow, or do you already have a faster way?

I made a compact chemfig toolkit for classroom chemistry

I kept repeating the same bond lengths, benzene substitutions, reaction arrows, and annotations in worksheets, so I wrapped the patterns into a small set of LaTeX commands called KKchemstruct.

The samples show substituted benzene rings, condensed structural formulas, reaction schemes, leaving-group marks, hydrogen bonds, and local sizing. It still uses chemfig underneath, so unusual structures can fall back to raw syntax.

Which part would be most useful in your own documents?

How Classical Chinese is traditionally annotated in Japan - and typeset with LaTeX

In Japanese kanbun kundoku, the original Classical Chinese text is retained while small reading marks are added:

  • Furigana - small kana showing the Japanese pronunciation
  • Okurigana - small kana that add Japanese verb endings and grammatical particles
  • Kaeriten ("return marks") - symbols telling the reader when to reverse the order of characters

Together, these annotations let a Japanese reading emerge without rewriting the original text.

I maintain gckanbun, a CTAN package for typesetting this with LuaLaTeX or (u)pLaTeX.

What is the most unusual writing system you have typeset with TeX?

한국 학생들은 AI를 어떤 용도로 가장 많이 쓰나요?

일본에서는 제 주변 학생들이 ChatGPT나 Gemini의 무료 버전을 많이 사용합니다. Claude나 Cursor는 코딩을 하는 학생이 아니면 아직 잘 모르는 경우가 많습니다.

한국의 중·고등학생이나 대학생들은 어떤 AI 도구를 가장 자주 쓰나요? 과제, 번역, 정보 검색, 코딩 중에서는 어디에 가장 많이 활용하는지도 궁금합니다.

단순히 서비스 이름만 나열하기보다, 실제 학교생활에서 어떻게 사용하는지 일본과 비교해 보고 싶습니다.

한국 학생들은 이런 풀이 정리 앱을 실제로 쓰나요?

한국 학생들은 보통 수학 문제의 풀이와 오답을 어떻게 정리하나요?

문제를 사진이나 스크린샷으로 올리면 AI가 풀이 과정과 해설을 정리해서 참고서처럼 읽기 좋은 PDF로 만들어 주는 방식입니다. 일본에서는 시험 공부나 오답 노트에 이런 형태를 활용할 수 있을지 관심이 생기고 있습니다.

한국에서는 직접 손으로 정리하는 편인가요? 아니면 비슷한 앱이나 AI 도구를 사용하나요? 한국의 입시 공부 방식에서도 이런 형태가 유용할지 궁금합니다.

저도 일본 대학 입시 수학을 대상으로 이런 도구를 만들고 있습니다. 현재는 일본어 중심이라, 한국 학생들에게도 쓸 만한지 솔직한 의견을 듣고 싶습니다.

中国的学生现在最常用哪些 AI 工具?

在日本,我身边很多学生主要使用免费版的 Gemini 或 ChatGPT。Claude 和 Cursor 在学生中还不算普及,至少我周围是这样。

中国这边呢?中学生和大学生通常使用哪些 AI 工具?是 DeepSeek、豆包、Kimi、通义千问,还是别的?

大家主要用它们来查资料、做作业、翻译,还是编程?免费版够用吗?

中国的数学教辅也会使用这样的视觉提示吗?

我想比较日本学习参考书与中国数学教辅的版式文化。日本的数学参考书常用小型视觉标签,在学生读题之前就提示“接下来该怎样思考”。常见的有:

• 要点:必须记住的核心内容

• 例题:典型的应用方式

• 解题方针:看完整答案之前的思考方向

• 星级:题目的难度

为了便于比较,我用 LaTeX 重新设计了三种原创示例:

  1. 带斜切标题的“要点”框

  2. 在一行中显示题号、主题和难度星级的例题框

  3. 使用浅色大编号的章节标题

我尤其想了解中国的中学教辅、高考复习资料或培训机构讲义:是否也会通过固定的框线、标签、颜色和星级来引导阅读?这些视觉元素通常分别表示什么?

三张图中,哪一种最像中国教辅,哪一种最不像?如果方便,也欢迎描述你见过的典型版式。

说明:图片是我用 LaTeX 制作的原创示例,没有复制任何具体出版社或学校的教材。中文由 AI 协助润色,我已核对内容。
