  Version Control Concepts Greater Control of Development  Makes it easy to keep track of incremental progress  Allows project to revert to any stage in its development  How Changes are Stored  “Snapshots”  “Deltas”  Branching and Merging  Multiple people can work on same project simultaneously  Branches can be merged into main line  Can result in conflicts  Must be solved through human interaction!  Tagging  Label particular set of versions as belonging together 7/9/2015 3LinQuest Proprietary Information

  Servers  Applications whichprovide content over a network  CM Servers  Web Servers  FTP Servers  SVNServe  Fully capable server packaged with Subversion  No web browsing capability  Apache  Free, open source, multi-purpose server  Initial setup can be arduous  Robust security  Django Development Server  Not for production purposes  Comes with Django Web Framework 7/9/2015 4LinQuest Proprietary Information

  Web Applications  Separationof Capabilities  In the beginning, everything was mashed together  Languages have divided responsibilities  HTML = Content  CSS = Presentation  Javascript = Behavior  HTML  The “backbone” of a website  Provides the raw materials  CSS  Controls layout of the web page  Font styles, colors, line breaks, etc.  Javascript  Decides how elements interact to user input  Ex. Drop-down menues, buttons, pointer clicks… 7/9/2015 5LinQuest Proprietary Information

  Django Web Framework Python Application  Intended to facilitate rapid web development  Origins in a Midwest newspaper company  Enforces Separation of Capabilities  Models interact with server-side databases  Views are responsible for data processing  Forms are extensions, more or less  Generate templates, handle HTTP requests  Templates = presentation  Written in HTML  Plug in CSS references, Javascript, etc.  Basically the typical web site  Servers  Comes with development server  Upload to Apache once finished 7/9/2015 6LinQuest Proprietary Information Urls.py HTTP Request Views Template Form Template Template Form Model Database Request Request

  Linux (Fedora 17) Open Source Operating System  Open to public through GNU general public license  Can sell new distributions as long as distribution is open source  Hmmm…no tech support?  Online community is HUGE  Distributions  Approximately 350 recorded distributions  Fedora 17  Maintained an updated by open community  Best features are included in Red Hat distributions  Look out! Updates are frequent and hefty. 7/9/2015 7LinQuest Proprietary Information

  Bash Scripting  Shells Act as fronts for the operating system  Accept commands from user, passes to kernel  Ex. Windows Explorer  Contains the desktop, start menu, task bar, file browser.  Bash  Type of shell made for Linux  Provides a command prompt for the user  Bash Scripting  Commands saved in a file make a script  Contains many basic programming functions  Control flow loops/statements  Arithmetic operators  Assignment operators  Boolean expressions 7/9/2015 9LinQuest Proprietary Information

  Virtual Machines  Alsoknown as VM’s  Definition  A completely isolated guest operating system installed within a host operating system  Ex. Fedora running in Windows  Hardware Virtualization /Software Emulation  Software techniques to overcome differences in hardware/software  Can be extremely difficult, and sacrifices performance  Separate from host OS all the while… 7/9/2015 10LinQuest Proprietary Information

  VirtualBox  VM Applicationfor Windows  Inserts itself below the kernel to intercept requests from the guest OS  Monitors guest OS to prevent damage  Completely isolated from host OS  How it Works (Basically)  XML settings file  Runs guest OS off of disk image  All hard disk requests from guest go to disk image  Everything stored in a directory in host OS  Routing HTTP requests was tricky 7/9/2015 11LinQuest Proprietary Information
