There are some facts:

  1. The notes are not tutorials!
  2. The notes are not written by a pro but a bookworm.
  3. The notes are not complete!
  4. The notes are always updated without notice!
  5. The notes always indicate the sources if ideas are not mine!
  6. The notes sometimes contain mistakes, that’s why I need your help to fix them.
  7. The notes have new brothers day by day.
  8. The notes with small dot () at the end of the title are not good enough!

Thanks and welcome to my world of notes.
