I can (and sometimes do) argue the benefits of Delphi all day long, but if you're just starting out or aren't using it for paid development, the price can be a barrier to entry.
So I was glad to see Embarcadero offering the Starter edition for free (until Sept 9th) and a Delphi Boot Camp, a free five day training webinar beginning on September 5th. Replays will be available afterwards. If you don't want to go looking for the replays, then sign up for the event, even if you can't watch it live. A notice is emailed to everyone who is registered when the replays are published.
All registered Delphi users, including users of the Starter edition, have access to an electronic copy of the Object Pascal Handbook written by Marco Cantu. This is the definitive writeup of the Object Pascal language as it exists in Delphi today and has been updated to cover 10.1 Berlin.
Embarcadero also had a C++ Boot Camp not long ago. The replays and Q&A are online, now. The promotion for a free license of C++ Builder Starter has expired, but there is a new promotion offering a heavy discount.
