wonderful academic papers about compilers. I'll illustrate how our view of compilers is really monolithic, and how compilers through time, and still today, are actually a continuum.Papers in this talk implementations of these abstractions is inappropriate for three main reasons: 1. it denies applications the advantages of domain-specific optimizations, 2. it discourages changes to the implementations the world’s fastest processors, many applications, especially those requiring high processor performance, have been ported to it. However, ☹ many other applications are available only under the x86 architecture

documentation • easy and comprehensive integration into existing projects - django CMS isn’t a monolithic application • a healthy, active and supportive developer community • a strong culture of good code statically hooked into the project’s urls.py. This is allright, but we can do more, by attaching applications to django CMS pages. We do this with an Apphook, created using a CMSApp subclass, which tells INSTALLED_APPS. This includes django CMS itself as well as its dependencies and other highly recommended applications/libraries: 'cms', # django CMS itself 'mptt', # utilities for implementing a tree 'menus', # helper
