Some Pitfalls of Inheritance
In "Some Pitfalls of Inheritance," Steven Black explores common mistakes developers make when applying inheritance in object-oriented programming, emphasizing its static and inflexible nature. He advocates cautious use, stressing that subclasses should truly be specialized types of their parents and highlighting the need to separate interface from implementation. Black also warns against deep inheritance hierarchies, improper behavioral overrides, and overly visible members when extending classes. He recommends combining inheritance with composition for flexibility, proper method call-ups to preserve general behavior, and thoughtful interface design to create maintainable, robust systems.

The Bottleneck in Modern Software Projects
Markus Egger argues that while Windows DNA, .NET, and component-based, distributed development offer major benefits, a critical bottleneck is the developer mindset and training: the broad community has embraced elegant new technologies in fits and starts, but many still cling to monolithic, familiar approaches. He notes a gap between enterprise needs and developer enthusiasm, with customers increasingly eager for distributed, flexible solutions even as the supply of capable DNA developers lags. Egger urges serious adoption and growth of a new generation of DNA-skilled programmers.
