• Are there any StatusNet toolkits for .NET?

  - by Broam

  There are plenty of projects out there that assist developers in posting things to Twitter; the one I can think of off the top of my head is Twitterizer. Are there any projects for posting to StatusNet? Given that StatusNet implements an API very similar to Twitter, I could probably modify/extend Twitterizer to do just that. However, I'd like to avoid reinventing the wheel if at all possible if something exists already.

• How significant are JPA lazy loading performance benefits?

  - by Robert

  I understand that this is highly specific to the concrete application, but I'm just wondering what's the general opinion, or at least some personal experiences on the issue. I have an aversion towards the 'open session in view' pattern, so to avoid it, I'm thinking about simply fetching everything small eagerly, and using queries in the service layer to fetch larger stuff. Has anyone used this and regretted it? And is there maybe some elegant solution to lazy loading in the view layer that I'm not aware of?

• Is it true that one should not use NSLog() on production code?

  - by jpm

  I was told this a few times in this very site, but I wanted to make sure this is really the case. I was expecting to be able to sprinkle NSLog function calls throughout my code, and that Xcode/gcc would automatically strip those calls out when building my Release/Distribution builds. Should I avoid using this? If so, what alternatives are most common between experienced Objective-C programmers?

• Problem with skipping login validation for authlogic

What must be done to avoid username validation without renaming the field?
