The Internet and its implications for your privacy and security

Dr Giovanni Moretti, School of Engineering and Advanced Technology, Massey University

RSNZ Manawatu Branch 2013 AGM

7.30 pm Tuesday, 19 November, Te Manawa – Art Gallery, 326 Main Street, Palmerston North

It’s easy to think of our connection to the Internet as “one way”, simply a means of accessing online services; however our online activity can provide a particularly detailed view into our lives. Imagine that your computer screen is actually a one-way window through to a room which is permanently staffed: they see every email, every Google search, every holiday plan, every online transaction, Skype conversation … store and share this data, and this goes on for years.

Beyond a vague unease about hackers and viruses, most computer users don’t give online security much thought; besides they think “there’s nothing on my computer I care about”. However, even if this is the case, there are unexpected and significant risks to your privacy and security.

This talk will introduce you to how data are moved around the Internet, why the information you freely provide online is valuable and how it’s being used, how your online communication can be intercepted by both official and unofficial means, and what you can do to help protect your data and keep your online activities private.

Giovanni Moretti is in the Computer Science Section of the School of Engineering and Advanced Technology at Massey University.

All warmly welcome

Biochar in New Zealand

Associate Professor Marta Camps, Massey University

RSNZ Manawatu Branch October 2014 meeting

7.30 pm Tuesday, 15 October 2013, Te Manawa – Art Gallery, 326 Main Street, Palmerston North

Plants store carbon temporarily while they are alive, but release it back to the atmosphere as CO2 when they die and decay. If instead plants are carbonised to charcoal, almost half of the carbon in the plant matter is converted to a stable form that can last in the environment for centuries. This long-term storage is called sequestration. To be called biochar, the charcoal must be put into soils with the intention to also benefit soil fertility. This practice has occurred in many pre-modern societies, including New Zealand Māori, and, particularly in poor soils, has been shown to improve fertility. This lecture outlines the opportunities and challenges for biochar in New Zealand.

Marta Camps is a soil scientist with a main interest in soil chemistry and carbon sequestration. She researches and teaches in the Institute of Agriculture and Environment at Massey University.
