I'm transitioning to Youtube! Don't worry, the podcast is not over :) I'll be making more and more screencast style videos instead of just audio podcast format. I'll still be having guest over and have conversations with them about the code and I'll be cross posting screencast episodes on the podcast as well. This new direction will allow me to explain the concepts and showcase the code examples better as the audio format can only do so much. Please hop on over to Youtube. You can find the channel here https://www.youtube.com/channel/UC6zcA3dAMUWN8E2_dlg_WyQ Please share, like, and subscribe to it as it will greatly help me get this channel up and running. Hope to see and hear your feedback and have better content quality there. Let me know what you think and I'm looking forward to hearing from you!…
