REACTION PAPER (PAY CHECK)

A computer engineer named Jennings awakens one day to discover that the last three years of his life and the work he did for a man named Rethrick during that time has been erased from his memory. He also learns that he agreed to the three years secret work and erasure in exchange for a huge sum of money.

Using the strange trinkets he previously left for himself, he goes on a journey in search of Rethrick, for whom he used to work, and how he knew that these worthless items would save his life.

On the movie Jennings reverse engineer software that already created and improve it. Nowadays Reverse-engineering is used for many purposes as a learning tool as a way to make new, and higher level of abstraction. Which is normally cheaper than currently released software in the market sale. And any efforts towards discovering one possible source code for the software are regarded as reverse engineering, Reverse engineering can make use of the clean room design technique to avoid copyright infringement. And it include security auditing, removal of copy protection "cracking", circumvention of access restrictions often present in consumer electronics, customization of embedded systems such as engine management systems, in-house repairs or retrofits, enabling of additional features on low-cost "crippled" hardware such as some graphics card chip-sets, or even mere satisfaction of curiosity.

On the other hand reverse engineering can also expose security flaws and questionable privacy practices which prohibit the creation or dissemination of tools or information that could be used to break technological...
