Yipp. Nothing changed since you left :D

Its something like a backup tool that saves the last 5 versions of a class/table/routine made by my colleague some years ago.

• Do you use an issue tracking / collaboration system? If so which one. Any you would recommend or immediately dismiss based on personal experience?

We have outlook tasks

• How do you keep track of large code bases? Thousdands of folders named backup1, backups2, ..., SVN, git?

a homemade tool

• Do you have a development server to which you commit and test features there, or do you rather run a local copy of caché and implement features locally first, then push to the server?

we develop everywhere (dev/test/prod) and mixtures.
