Best Software architecture & design Videos
The 177 Software architecture & design videos here were recommended by different people across different months. Choose by who it is for: 8 introductory, 132 intermediate, 20 for a general viewer, and 17 for someone who wants the harder derivation. Most of them are a talk. What they share is that one speaker finishes a claim, and the examples exist to hold that claim up. Channels you will keep seeing include ClojureTV, Confreaks, Strange Loop Conference.
