A prisoner developed a software to manage the jail staff

In 2014 he also had written a 368-page novel 'Four Friends'.

He says he had little knowledge in software development. So he taught himself more than 12 hours initially.

I wonder what made him to be so focused and creative, given that he is convicted for life.

I find hard to settle for more than 4 hours.

Cool! I think it's great that he has access to computers and is able to better himself and others even while he's in prison.

Besides the benefits of doing something productive, I wonder if it also provided him with additional comforts in prison?
