Discover gists

Summary

Random set of notes and links that have helped me in the saga to get Ubuntu 22.04 up and running on my 2017 MacBook Pro These notes are mainly for myself in the event that I have to do this again some day. But if you find them helpful, that's great.

Important update

Unfortunately the MacBookPro that I bought second hand turned out to be a dud with some serious hardware flaws that didn't show up until a couple of months after I'd bought it.

I've since purhcased another laptop so I'm not going to be able to maintain this GIST.

I'll leave it here for now in case others want to contribute updates, or clone it. If you feel it's out of date or misleading or a waste of time, let me know in the comments and I'll remove it.

Solveit Reference

What is Solveit?

Solveit is a "Dialog Engineering" web application for interactive development. Unlike ChatGPT (pure chat) or Jupyter (pure code), Solveit combines three message types in one workspace: code execution, markdown notes, and AI prompts. Users build solutions incrementally—writing a few lines, understanding them, then continuing—rather than generating large code blocks.

The AI sees the full dialog context (code, outputs, notes, prompts) when responding -- but only those ABOVE the current message. Users can edit any message at any time, including AI responses—the dialog is a living document, not an append-only log.

The dialog is a running ipykernel instance. A "dialog" is like a "Jupyter notebook", and uses a compatible ipynb file format, but provides a superset of functionality (in particular, "prompt messages"). A "message" is like a "Jupyter cell", with additional attributes stored as ipynb cell metadata. Most standard jupyter functionality is supported (including cell

[공통] 마크다운 markdown 작성법

영어지만, 조금 더 상세하게 마크다운 사용법을 안내하고 있는
"Markdown Guide (https://www.markdownguide.org/)" 를 보시는 것을 추천합니다. ^^

아, 그리고 마크다운만으로 표현이 부족하다고 느끼신다면, HTML 태그를 활용하시는 것도 좋습니다.
