Windows 7 systems have more powerful features than XP systems

Windows 7 has a very strong compatibility. If it is win7 just out of the time to say this will be sprayed dead, but now windows 7 compatibility has almost exploded XP. In another 1 years, it may be really over. These are more powerful features of Windows 7 systems than XP systems. Win7 system replaces XP system I believe the coming soon, the main reason is that the XP system does not update the patch. Al

All software systems are legacy systems

different teams open the codebase, it's easy to see what's going on, and that's the foundation of a good architecture. There is no need to over-simplify or prepare exhaustive documentation for the architecture; Good design describes itself in many ways. The system behavior in the production environment also illustrates its design, for example, a structure with a very ugly dependency, whose behavior often looks like a caged beast and is restricted everywhere. Think about the developers who are g
