This repository contains my personal notes and interpretations based on third-party resources (such as online courses, YouTube videos, books, and mock interviews).
These summaries are:
- Not official material,
- Not endorsed by the original creators, and
- Not intended to be a replacement for the original courses, books, or videos.
All rights to the original source content remain with their respective creators.
If you are the owner of a work and you are unhappy about the presence of a summary related to your material in this repository, please contact me at alisolphp@gmail.com. I will review it and remove it if necessary as soon as possible.
LearnHub is a curated collection of concise, high-signal summaries for courses, YouTube videos, books, and mock interviews.
It is designed to help you:
- learn faster,
- review smarter (for example before interviews),
- and use your favourite programming language and natural language when drilling into details with an AI assistant.
For the full story and philosophy, see VISION.md.
You can combine these summaries with an AI assistant to:
- Ask follow-up questions about any section of a summary.
- Turn flashcards into interactive Q&A practice.
- Translate explanations into your preferred tone and natural language.
- See examples in the programming language you are most comfortable with.
- Get freshness notes after each explanation (useful for older books and videos).
- Simulate interview-style discussions using the mock interview summaries.
- Go deeper into the topic with advanced AI hints at the end.
Typical workflow:
- Open a
summary.*.mdfile for the topic you are studying. - Use the AI buttons at the top (teach / flashcards / quiz / projects / …), or:
- Highlight a section and ask your AI assistant to go deeper, ask “why?”, or request code examples.
See AI_FEATURES.md for detailed routes and prompts.
This is an opinionated, curated project. Summaries are not crowd-sourced – they are maintained by the project owner (and maybe a small trusted core team later).
You can still help a lot by:
- requesting new topics / resources,
- reporting broken links or AI buttons,
- suggesting better prompts and workflows,
- improving docs, and
- sending small, focused code improvements.
Read CONTRIBUTING.md for:
- what kinds of contributions are welcome right now,
- what is out of scope (e.g. editing summaries),
- and how to open good issues / PRs.
