I spent most of the morning writing block 142 which was related to learning LangChain. 

It took a little of an hour to complete the beta DeepLearning.AI LangChain for LLM Application Development short course [1]. It was a pretty good course and it included a mix of both notebooks and video. The nice part of the notebooks was that they were already set up and ready to run in sync with the video.
