Techniques to interact with an application via messaging are described. Cell extracts that provide enhanced yields of soluble proteins using in vitro protein synthesis methods are provided. The chip includes a bonding layer. A CRC hash operation is performed to the MAC address by using the m-bit CRC function to obtain a hash value. The detection, preferably by tuned coils, of one or more electromagnetically-induced resonant frequencies at shifted locations indicates the presence of one or more flaws in the metallic structure under test. The receiving side of the message system can be scaled across multiple machines andor across available resources of any given machine.
