Rubberduck – refactoring in VBA

Hi all, recently came across an interesting Rubberduck project. Did you think that VBA is dead and buried? It looks like it’s not going down that easily! Rubberduck is a COM Add-In for the VBA IDE that makes VBA development even more enjoyable, by extending the Visual Basic Editor (VBE) with menus, toolbars and toolwindows that enable things we didn’t even think were possible when we first started this project. If you’re learning VBA, Rubberduck can help you avoid a few common beginner mistakes, and can probably show you a trick or two – even if you’re only ever writing macros. If you’re a more …

Hans Rosling and data visualisation

Just a wonderful example of data visualization, and what can be done with diagramming. I first encountered Professor Hans Rosling talks on TED – really exciting. For example, see the recent talk about Religions and Babies where he shows what the world population will be, or the talk “washing machines” (“Even the Hard Core of the Green Movement Use Washing Machine”). I wish I had him as a professor when I studied in Uni =) PS. Now the technology was acquired by Google, and is is available as part of the the project Google Public Data.
