Re:Tutor app can now teach you YouTube videos on Friday October 23, 2026 @08:46AM (#50208141)
Our local, open source app, that teaches you all the concepts from source materials like books and online documentation, can now do it directly from YouTube videos or playlists.

Show HN: Tutor, a self-hosted LLM tutor that teaches you your books or docs

Reading does not always guarantee retention, especially for complex materials. So I created this tool that extracts the concepts and teaches them back to you (and then tests you as much as you need) so you can really learn the study material. This is a local project (hosted option coming soon) and it works for EPUB, PDF books or online HTML pages. AI API key needed (Luna or Haiku makes this...

This needs a way to manually set the location. Browser location is so off sometimes. Without that is useless for me.
Here is another perspective:

- the first one (branchless) use the condition to SAVE the correct value (< 500): it temporarily writes any current value to the same index i, always overwriting the previous value, effectively saving it (by moving forward to i+1) only when the value is right (small number). Downside of this simple function: the last value may be bigger than 500

- the second one use the condition to ADD the value, when it is 100% sure it is a correct small number

I don't know, I am quite a power user of some stuff he removed. Especially Services! that is a gem in itself if you know how to use it.
I built this script to monitor OpenRouter's models launch and it works very well so far (it will sent me a Slack message every time a new model drops). It was vibe coded as a throwaway project to test some models, but it eventually stuck and became a useful tool. So I though to share it, in case somebody else may find it useful.
Re:Ask HN: What browser extensions are a must-have in 2021? on Tuesday November 23, 2021 @06:31PM (#29324968)
I am looking and I don't see my preferred extensions without which I cannot live (I won't repeat the already mentioned ones):

- Selection Context Search - very extensible addon which will allows you to select in page and use that for opening an URL: search in any engine, add to search strings in Wikipedia, IMDB, torrents, almost anything

- Ant Video Downloader - downloads any video from page

- Bookmark Tab Here - bookmark by right clicking directly on bookmark folder

- HistoryBlock - blocklists sites from history (for example google.com, your search history)
