Often when vetting software for acquisition or venture investment certain questions go unanswered. Typically in these situations buyers and investors focus on market share, gross revenues, projected earnings and other financial data. While focusing on capital debt, many will ignore technical debt. Some key questions are left unanswered. What is the state of the code? What is the quality of implementation? How easy will it be to fix and to add new capabilities? Robert L. Glass talks about the... + continue reading

Mastering Complexity is a new Dependency Structure Matrix (DSM) book by Stephen Denker. Steve is a management consultant who has worked with DSMs for many decades and his vast experience is reflected in the book. This is easily one of the most approachable books that I have come across. The early chapters were easy to read, well-illustrated, and explained the concepts well. However, what comes as a surprise was when the simple concepts of the early chapters give way to much deeper... + continue reading

We decided to take a look at the architecture of the Android Kernel. We selected the panda configuration for no particular reason - any other configuration would have worked just as well. The kernel code is written in C and it is derived from the Linux kernel. So, our approach will work on any configuration of the generic Linux kernel, as well. Now we all know that C/C++ is a complex language and so we expect the analysis to be hard. But that difficulty just refers to the parser. Armed with... + continue reading

Johan van den Muijsenberg just published (in Dutch) his analysis of ArgoUML in a magazine published by the Java User Group in Netherlands. The brilliance of Johan's analysis is in how logically straightforward it is and how that analysis yields clearly identifiable architectural issues and fixes. It is yet another example of how easily architecture erodes from its intended design. If more teams were to focus on fixing "bugs" in architecture, they would reap rich dividends in improved quality... + continue reading
What Star Trek Can Teach Us About Software Architecture

The writers of Star Trek Voyager envisioned a game that was worthy of challenging the superior mind and intellect of a Vulcan. They called it Kal-toh. To the human eye, Kal-toh looks to be a high-tech fusion of Jenga and chess. Lieutenant Tuvok of the starship Voyager would be quick to tell you "Kal-toh is to chess as chess is to tic-tac-toe.” In Kal-toh, the players are presented with rod like game pieces that are in total chaos. This could be compared to legacy code with no discernable... + continue reading
