Do you know where your variables are? | |

I can easily think of two situations where those have driven me MAD.
I need to connect to a different dateabase than I used to for party of an application. I have to change which variable names I'm using to use the right database. I wrote one app, where it had a kernel so to speak, w/ a logger attached. Creating a new kernel would create a second running copy of everything, 'cept the logger, 'cause it was a singleton. Grrr! Don't privatize your constructors! If I want a shared object, good, if not, it's just as good. The only thing I ever want globals are things like, numbers. 1 only has one value. 1!
