This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.
Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.
I have collected and moderated these ideas from various public sources and put into one place so that problem solvers and solution developers may find inspirations. Because I wish to update it regularly, I have setup as a single page wiki. You may try these ideas on hackathons/competitions/research; some are quite intense problems and some are not. Many of the problems were prepared keeping Dhaka/Bangladesh in mind, but of course can be applied to just about any underdeveloped/developing and sometimes developed countries.

| Convert YouTube subtitles(vtt) to human readable text. | |
| Download only subtitles from YouTube with youtube-dl: | |
| youtube-dl --skip-download --convert-subs vtt <video_url> | |
| Note that default subtitle format provided by YouTube is ass, which is hard | |
| to process with simple regex. Luckily youtube-dl can convert ass to vtt, which | |
| is easier to process. |
Short (72 chars or less) summary
More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).
Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages
