Hackety Hack begins by introducing kids to Ruby, _why’s programming language of choice. Then it explains that programming is nothing more than giving a stupid, unthinking computer your commands. You are its boss. It answers to you. And you can make it do nearly anything with simple keystrokes and enough practice.

A long paper trail of software engineering studies has shown that many internal code metrics (such as methods per class, depth of inheritance tree, coupling among classes etc.) are correlated with external attributes, the most important of which is bugs. What the authors of this paper show is that when they introduce a second variable, namely, the total size of the program, into the statistical analysis and control for it, the correlation between all these code metrics and bugs disappears.

Hearing that Windows 8 would use HTML5 and JavaScript for its new immersive applications was, therefore, more than a little disturbing to Windows developers. Such a switch means discarding two decades of knowledge and expertise of Windows development—and countless hours spent learning Microsoft’s latest-and-greatest technology—and perhaps just as importantly, it means discarding rich, capable frameworks and the powerful, enormously popular Visual Studio development environment, in favor of a far more primitive, rudimentary system with substantially inferior tools.
