Letting Defects Coalesce

The quick-fix solution. An approach to bug-fixing that should be reserved for those critical problems impacting production systems. Or where you're in a high-pressure scenario where the software must ship. We all do it. Or at least, we should be hammering out these quick-fix solutions all the time. Because if we didn't, it'd mean we're waiting till we figure out what the perfect program looks like. The problem at hand takes a back seat to our own misgivings about the code we've put together. Quick-fix solutions enable us put software in the hands of users. Period. But that doesn't restrict us from thinking about defects over a longer period of time in an attempt to really understand their causes and effects. Are they just symptomatic of a deeper issue within the system's design?

ArgoUML doesn't support abstraction dependencies.

In the UML, an abstraction relationship shows that one element is an abstraction on another. This is rendered as a dependency relationship stereotyped as abstraction. This is not an available stereotype for dependency elements in ArgoUML 2.6. The abstraction dependency doesn't necessarily need to be attached to the dependency directly.

The UML defines three predefined stereotypes in which the abstraction stereotype is attached to. These are derive, refine, and trace. However, when modeling dependencies, these stereotypes aren't available either.

So, if you have a need to specify these types of dependencies in your models, I wouldn't recommend ArgoUML (although I would recommend it for other UML modeling purposes). In fact, I don't even think Umbrello or Gaphor will get this right.

Strange Gnome screenshot behaviour

I noticed some strange Gnome behaviour when attempting to take a screenshot. This only seems to happen in firefox. If I want to take a shot of an expanded menu on a form, Gnome wont let me. I assume that this has to do with the window focusing. It seems to me that this would be, well, not a common requirement but it is a failed use case nonetheless.
