TeachBack: You don't know it, until you can teach it back!

Two new tools, LastFix and TeachBack, address specific learning and technical challenges. LastFix serves as a personal troubleshooting memory system for users like Tilak and Saumya, preventing repetitive searches for previously solved technical issues such as Git conflicts or Wi-Fi problems. Meanwhile, TeachBack helps a friend at an electricity distribution company escape tutorial hell while learning Python. It moves beyond passive video watching and synthetic projects to ensure knowledge is mastered through the act of teaching.
