| - | * Software platform | + | |
| - | * Added extension which can simulate writing log entries | + | |
| - | * For testing Write Flush; W.F. needed log entries to write | + | |
| - | * Allows us to turn off all other extensions | + | |
| - | * Spent alot of time restructuring for easy scripting | + | |
| - | * XML config files | + | |
| - | * Purpose is towards management research | + | |
| - | * Scripts what the experiment will do | + | |
| - | * Downloads XML config from https server | + | |
| - | * Phone rejects CS's TLS cert, coded a white list for certs | + | |
| - | * Phone ID's itself, can be given a personal XML config | + | |
| - | * Very easy format (see below) | + | |
| - | * Improved stability & error handling | + | |
