Today I had my first chance to give a talk about TDD. as this was my first talk ever . it felt weired and before the start of the talk, I tried to focus and some colleagues gave me some hints before the start and gave me guidance and some material to help me prepare for the talk. it took me full day to be able to get an idea on what I will include in my slides and how to keep the attendees awaken and interested as much as I can throughout the time of the session. anyway, it went well and had good feedback from the attendees. here you can see the slides and leave me your comments to enhance this talk in the future.
