Likewise, I'm sorry you've had a bad standup experience. A standup should absolutely not be an interrogation, and perhaps I dwelt too much on the "competitive pressure" aspect. That competitive pressure should come entirely from within a developer, just from the normal psychological desire to achieve and do a good job and to know that someone cares about what you're doing. The manager actively needs to counteract the competitive part, to ensure that it's okay in the standup to say "I'm stuck" or "I fucked up" or "I need help".
