Descrambling Parallel Build Logs

One of GNU make's many features allows you to shorten build times by running more than one command at a time. If your dependencies are all correct, or nearly correct, this can give you a significant improvement, and since it's built into the tool you get it "for free." But GNU make's parallel build feature—often called "dash j mode," after the command-line option that is used to enable it—is not without drawbacks. The worst of these is that GNU make parallel builds can produce incorrect results if the build dependencies are not sufficiently correct.

Thinking About People, Process, and Product: A Principle that Works at Work

All projects involve the three P's: people, process, and product. People includes everyone who influences the project. Process is the steps taken to produce and maintain software. Product is the final outcome of the project. To keep these three in harmony, you must observe who is trying to do what to deliver what. Usually, two of the three P's are mandated, and the third one is chosen appropriately. Although this is common sense, it is not common practice. Dwayne Phillips discusses the issues and challenges that affect us all on every project. Learn about the ideas and questions to consider to help you work through these issues.
