Machine intelligence is real intelligence
AI or artificial human intelligence (AHI) is was originally conceived to develop methods to help machines exhibit human-like thinking processes. However, we have far from achieved this objective. Instead a discipline of real machine intelligence (RMI) matured from these researches. Why deal with something that is artificial when machines have some form of real smarts [...]

Disappearing Nested User Controls in VS2005
When trying to nest usercontrols, the child usercontrol sometimes disappears off the parent usercontrol. This is a commonly reported bug on the internet, and there’s a hotfix FIX:#842706 for vs2003 but not for vs2005, and its extremely annoying. What happens is that after placing the MyControl on your MyForm.designer.cs, it just disappears when you save MyParentControl in wysiwyg mode.
For me, the problem occurs because the Component Designer auto-validates & re-generates your MyParentControl.designer.cs code again. And, if your MyControl constructor requires initializing parameters, vs2005 will just delete that instantiation in MyParentControl.designer.cs.
