• More Bugs in the SharePoint API - Kris Syverstad points out some more annoying "features" in the SharePoint API. This is getting really old.
• Office 2003/XP Addin: Remove Hidden Data - Have you ever noticed that you can't fully remove "track changes" information from a document? Well now you can. Everyone should have this addin installed.
• Code Theft - CodeAse has apparently pirated Frans Bouma's open-source product LLBLGen 1.x and packaged it up as their own. Shame on them. Boycott CodeAse! Download LLBLGen 1.x for free! Or if you want something a little fancier, buy Frans' LLBLGen Pro.
• ASP.NET ViewState... Good or Evil? - My vote is for evil, but Scott Hanselman is at least making me think carefully about the alternatives.
• P/Invoke Interop Headers for C# - Every tried to write a P/Invoke signature by hand? It can be challenging for some parts of the Win32 API. Although of course, it is so much better when you don't have to do this. [via Brad Abrams]
