+# Programming Skills
+
+This presentation covers the basic skills required to be a programmer...
+
+ ...that **don't** involve actually writing code.
+
+# Files and Directories
+
+* The House/Rooms/Drawers Metaphor
+  * directories store files and keep everything in your ‘house’ organized
+
+# The Command Line
+
+    ls
+    cd
+    pwd
+    echo
+    touch
+    cat
+    mv
+    cp
+    rm
+
+# Special Directories
+
+* Current directory 
+  * `.` ("dot")
+* Parent directory
+  * `..` ("dot dot")
+* Home directory
+  * `~` ("tilde")
+
+# More about directories
+
+* Explain where home and root are located in relation to all directories.
+* Explain difference between absolute paths (starting with a /) and relative paths.
+
+# Text Editing
+
+* text editor vs. word processor
+  * similarities and differences
+* Have group open editor, create and save file with explanation of how and where files are stored.
+  * after change, go to command line and `cat` the file to see 
+* Explain file extensions and file types. 
+  * File types tell the editor how to color the special words in each language. 
+* Explain difference between the buffer (in the editor’s memory) and the file (stored on disk).  
+  * Emphasize the importance of saving the buffer to a file before trying to run it with ruby.
+  * "Save" makes things unsafe
+
+# Compilers, Interpreters and Programming Languages
+
+* Use metaphor of programming language as an agreed set of rules about syntax for writing source code that is sent to the interpreter and translated into byte code.
+* Explain that byte code is the binary that machines understand and use for executing instructions.
+* Use metaphor that CPU is like a guy in a factory executing commands that it is handled, and the source code are those instructions.
+* Explain differences between compiled vs. dynamic languages.
+* Tie everything together by explaining that source code are instructions that are translated into language that machines understand and can execute.
+
+# Memory, CPU, Hard Disk
+
+* Very briefly explain how a computer works and all the moving parts (literally) starting with hard drive, memory, and CPU.
+* Give the group basic understanding of where the source code is stored and how and where it is executed.
+
+# Operating System
+
+![](img/os_x_logo.jpg)
+![](img/windows_logo.gif)
+![](img/linux_logo.gif)
+
+* The OS is a program that runs other programs
+  * the term "multitasking" actually started with computers and migrated to common usage
+* It also helps programs communicate with hardware (video, memory, disk, network...)
