Gamasutra is a great resource for stories and tips from developers in the industry. It focuses on future trends and breakdowns of development cycle's successes and failures. Although Gamasutra is more industry focused, and doesn't focus on low level implementation details, it provides a good high level overview of practices to adopt and avoid, as well as providing updates on what's new in the gaming industry.
