| That will cause the crash catcher (debuggerd) to freeze the process, | |
| allowing you to use gdb/gdbserver to debug it. | |
| In the source tree, after you "source build/envsetup.sh" and use | |
| "lunch" or "choosecombo", you will have a shell command called | |
| "gdbclient". By default, it expects to debug "app_process" on port |

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:

Adapter: a design pattern that translates one interface for a class into a compatible interface.
Admin: short for 'administrator'; very commonly used in speech or online to refer to the systems person in charge on a computer. Common constructions on this include sysadmin and site admin (emphasizing the administrator's role as a site contact for email and news).
Counter: a variable or user interface that counts occurrences or repetitions of some phenomena or event.
