I agree. But I think for that to be a substitute for thorough testing isn't good. >>In the past, John kept bugs low such that a release could be made at almost >>any time and in fact John created versions quite often. > > > Unfortunately, it seems John now has less time than in the past. > > >>But if we are switching to a mode where code moves in fast and bugs are left >>for others to find, then that release schedule/policy that John has followed >>will result in what Carlos suggests.

Probably not anyone on this list, because these are all the people looking for new features. But the rudimentary user who finds bugs in a program s/he tries gets a first impression and then dismisses the product. It's hard to get people back from that. Case in point? Windows. A few blue screens and one becomes a linux user and doesn't look back. > When I > find a bug, I fix it (or someone else does), update code, rebuild and > the bug is gone. You have to remember that there are many users out there who aren't like you or me. They don't have the confidence that if a program they decide to use has a bug, they can notify a discussion list, get a development version and compile it. >>>>Once this happens, it could be quite tedious (and not much fun at all) >>>>to clean it up again.

But John does have a higher level of patience... most days. It's a matter of hastiness. If the premise is, as Thomas suggests, "bugs happen" but someone will find them, it seems to me programmers are more inclined to be sloppy, which I'm not saying anyone is. > I assure you I don't intentionally leave bugs in my patches.

Yes, easy. But maintaining quality is more of a process issue. If one looks at industry programming and the way it has been moving, the process includes report bug, assign programmer, fix bug, someone else confirm bug fixed. There are usually two components to software development: source control and bug tracking tool. The bug tracking tool is the procedural part of the development.
