cMySQL_DB is a class that handles MySQL database connections and queries. It can select the database to access, escape literal text values to use in queries, execute arbitrary SQL queries, retrieve query results as arrays or objects, retrieve the count of query result rows, retrieve the number of affected rows, and retrieve the last inserted table record identifier. Errors can also be logged.
pingspray is a tool that generates network traffic for EMC (electromagnetic compatibility) tests. It can generate both random and periodic patterns of data as suggested in some EMC standards. It uses ICMP echo requests (ping) to generate traffic, and when it works as intended, it will generate traffic in both directions.
