Another day another free ebook from Packt. Today's feature title is Perl 6 Deep Dive. Given the steady decline in the use of Perl over the last decade I'm not sure if this will appeal to anyone.
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.
