Demand paging is the ability for the operating system to copy a disk page into physical memory only if an attempt is made to access that page. To accommodate demand paging the DLLs and EXEs should be mapped into memory (MapViewOfFile, mmap) allowing the operating system to do the magic. IO Request Caches. Demand Paging.

So the thrust of this paper is to shift our thinking from programming / software development / software engineering as the process by which we create a point-in-time program to implement a given procedure, and instead start to focus on a program (software system) as an evolving entity over time.

Browser vendors fund their industrial-scale software engineering projects through integrations. Search engines pay browser makers for default placement within their products. From this data, we can assume a baseline cost to build and maintain a competitive, cross-platform browser at $450 million per year.

On the other hand we have good old-fashioned native apps that you install on your operating system (a dying breed? On the one-hand we have ‘cloud apps’ which make it easy to access our work from multiple devices and to collaborate online with others (e.g. Google Docs, Trello, …). See e.g. Brendan Burns’ recent tweet ).

SQL works with the operating system to detect the non-volatile storage devices and leverage them for the tail of the log. Bob Dorr – Principal SQL Server Software Engineer. SQL Server will detect the request on the DAX based volume and create the non-volatile, tail of log cache of fixed size for the database.
