The challenge with Postfix, or with any piece of software, is to update software without introducing problems.

This will surprise some of your readers, but my primary interest is not with computer security. I am primarily interested in writing software that works as intended.

However, writing software without defects is not sufficient. In my experience, it is at least as difficult to write software that is safe - that is, software that behaves reasonably under adverse conditions.

In a previous life I wrote the software that controlled my physics experiments. That software had to deal with all kinds of possible failures in equipment. That is probably where I learned to rely on multiple safety nets inside and around my systems.

In my country, Gabon, entry into the digital age, which is the future, can be seen in numerous sectors - from telecommunications to security, finance, and hospitality.

I am a huge fan of using social media to connect with people because I think there was this 'ivory tower' aspect of journalism where people might read a byline for years but have no idea about the person who was behind it and never get to communicate with them or ask them a question.

By being able to write a genome and plug it into an organism, the software, if you will, changes the hardware.

Straight-up digital delivery will be the way the future works.
