Generic programming is an effective methodology for developing reusable software libraries. Many programming languages provide generics and have features for describing interfaces, but none completely support the idioms used in generic programming. To address this need the language G was developed . The central feature of G is the concept, a mechanism for organizing constraints on generics that is inspired by the needs of modern C++ libraries.

Foundation is a preservation system for users’ personal, digital artifacts. Foundation preserves all of a user’s data and its dependencies—fonts, programs, plugins, kernel, and configuration state—by archiving nightly snapshots of the user’s entire hard disk. Users can browse through these images to view old data or recover accidentally deleted files. To access data that a user’s current environment can no longer interpret, Foundation boots the disk image in which that data resides under an emulator, allowing the user to view and modify the data with the same programs with which the user originally accessed it.

The microcontroller is widely used in many devices, which works in environment. The microcontroller has to face the challenges from EMI, voltage stability, crystal failure and much other interference. If the interferences are strong enough to disturb the operation, the system design should be secure enough to deal with these matters, one good practice is to reset and go on with previous normal operation state . However, a simple reset is not enough at all. I will demonstrate the basic principle for the system reset and state restore. Please keep in mind that the terminologies used in this article may come from different microcontrollers.

If an application is useful, then the network of users will grow crazily fast at some point. As more and more mission-critical applications are now running on Java EE, many Java developers are caring about scalability issues. However, most of popular Web 2.0 sites are built with script languages, and there are a lot of voices to doubt the scalability of Java Applications. In this article, Wang Yu takes real world cases as examples to explain ways on how to scale Java applications based on his experiences on the laboratory projects, and at the same time, bring together practice, science, algorithms, frameworks, and experience on failed projects, to help readers on building high scalable Java applications.
