Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers


This issue includes: Headlines, Poll Results, Feature: Wine Architecture, Keeping Track of Wine and Discussions on wine-devel.

"Feature: Wine Architecture
With the fundamental architecture of Wine stabilizing, and people starting to think that we might soon be ready to actually release this thing, it may be time to take a look at how Wine actually works and operates...."

"Wine is often used as a recursive acronym, standing for "Wine Is Not an Emulator". Sometimes it is also known to be used for "Windows Emulator". In a way, both meanings are correct, only seen from different perspectives. The first meaning says that Wine is not a virtual machine, it does not emulate a CPU, and you are not supposed to install neither Windows nor any Windows device drivers on top of it; rather, Wine is an implementation of the Windows API, and can be used as a library to port Windows applications to Unix. The second meaning, obviously, is that to Windows binaries (.exe files), Wine does look like Windows, and emulates its behaviour and quirks rather closely."

"Note: The "Emulator" perspective should not be thought of as if Wine is a typical inefficient emulation layer that means Wine can't be anything but slow - the faithfulness to the badly designed Windows API may of course impose a minor overhead in some cases, but this is both balanced out by the higher efficiency of the Unix platforms Wine runs on, and that other possible abstraction libraries (like Motif, GTK+, CORBA, etc) has a runtime overhead typically comparable to Wine's."
