Another day another free ebook from Packt. Today's feature title is Drupal 8 Development Cookbook. Given the limited take up of Drupal 8 this title probably only has a niche audience.
There are other titles that are always free on the same page. Topics include Big Data & Data Management, Machine Learning / AI, Python, Mobile and Web App development.
The quality of Packt books varies wildly. I have picked up almost 500 free ebooks from them over the years. Most I've never read.Some were so bad I wished I didn't waste the bits downloading them.
