Montags and Clarisse's realtionship is weird. If she had not died I think they would have become a lot closer throughout the book. Clarisse seemed to bring out a different side of Montag. They way she would ask him questions and make things for him.
JKS stands for Java KeyStore. It is a repository of certificates (signed public keys) and [private] keys. You can export a certificate stored in a JKS file into a certificate file. You can use the keytool utility found in Java distributions to maintain your JKS trust and key repositories.
JavaScript Object Notation (aka JSON) is a very popular alternative to XML for transmitting data to the web browser. Flexjson is a lightweight library for serializing and deserializing Java objects into and from JSON. What's different about Flexjson is it's control over what gets serialized allowing both deep and shallow copies of objects. Most JSON serializers mimic object serialization libraries and try to serialize the entire object graph from the object being turned into JSON.
