Anybody know how to find more of his videos? I have already used google but failed. In particular on http://www.objectmentor.com/ I found nothing. Thankfully to Ilja I watched http://www.infoq.com/presentations/principles-agile-oo-design and want more. I have also bought and start reading his book Agile Software Development and for me videos would be a nice supplement to the book.
I don't think it's available. Remember that he makes his money by people paying for visiting his tutorials (besides other things, of course).
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
The video on InfoQ stopped rather abruptly, didn't it? Too bad.
The Principles Patterns and Practices book, as Uncle Bob calls it, covers the same material but not with his inimitable presentation style.
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
