. How they hack your passwords

Recording of “How they hack your passwords”

Presented by U3A Technology Corner, Helen Smith (U3A Nunawading) - 20th July 2022

Think your passwords are safe? Find out how the ‘bad guys’ get your passwords without you knowing. Explore ways of protecting yourself, even if your passwords have been ‘stolen’. This session will help you appreciate the risks involved with poor passwords and give you some strategies for keeping your account logins safe.

What is hacking and why should you care? Do you really need to worry about your U3APP login or just your bank account? How can you check if your email address has been stolen? Are your passwords following a common pattern? What are the best ways of generating and ‘remembering’ your passwords? These are just some of the questions answered in this riveting session.

The 2-hour recording of the presentation is available by clicking on the link below.

. Vaccination Requirements at U3APP

As was reported to the last E-Bulletin, the Victorian DHHS and the City of Port Phillip have changed the COVID restrictions, effective as of 11.59pm Friday 22 April 2022. The following requirements will no longer apply for Community Centres:

  • All staff, vendors and attendees are fully vaccinated.
  • Electronic QR Code Check-in is completed on arrival.
  • Covid Marshal is appointed.

The new COVID restrictions mean vaccinations are no longer mandated for Community Centres, like U3APP. Therefore the Committee of Management has decided, unanimously, that the current U3APP policy that requires members to be vaccinated to attend face to face classes or events is no longer necessary. This is in line with both the current Victorian DHHS and CoPP restrictions.

Department of Health and Human Services currently recommends a 4th dose for those over 65 years which they are calling the Winter dose.

The Committee of Management recommend members keep their vaccinations up to date for their own safety but there is no longer the need to send proof of vaccination to U3APP.

Entry to Mary Kehoe Centre and the other U3APP venues no longer requires QR code check-in or a COVID Marshal. U3APP thanks all the office volunteers and face to face tutors for their hard work associated with the COVID Marshal process over recent months.

Keep Safe.

. Changes to COVID Restrictions


The Victorian DHHS and the City of Port Phillip have changed the COVID restrictions, effective as of 11.59pm Friday 22 April 2022. The following requirements will no longer apply for Community Centres: 

  • All staff, vendors and attendees are fully vaccinated.
  • Electronic QR Code Check-in is completed on arrival.
  • Covid Marshal is appointed.

For U3A Port Phillip, this means that:

  • Members entering a U3APP venue are no longer required to do the QR check-in or have their check-in and vaccination status checked before entering the venue.
  • There is no requirement for a check-in marshal at the entrance to the venues.
  • At the Mary Kehoe Centre, the front door no longer needs to be locked.
  • At the other Community Centres, entry remains through the locked doors.

The requirement for members to be vaccinated in order to attend face to face classes or events is under consideration by the U3APP Community of Management, and remains in effect until further advice.

To maximise the safety of our members, ventilation and contact tracing remain important.  

  • Everyone is asked to increase the ventilation of the rooms by opening the doors and windows during classes. The windows in Room 3 at Mary Kehoe are scheduled to be replaced on 6th June, such that they can be opened.
  • Any member who is diagnosed with COVID is asked to advise the Health & Safety Office by email on hso@u3app.org.au, to enable contact tracing of inadvertent exposures to COVID in the U3APP venues.

Keep Safe.

. The Role of Seaweed in Mitigating Climate Change

Robyn Walters, of the newly formed Climate Champions group, writes this introduction for their topic of the month, written by David Sonenberg, The Role of Seaweed in Mitigating Climate Change.

"Thanks to our enterprising tutor, Hannah Len, the Climate Change U3APP Class has created a follow-on group called Climate Champions.  We connect to continue investigating, sharing ideas and being proactive about Climate awareness. Hannah stimulated us to educate ourselves about topics we had not known about before such as:-

  • Carbon Capture
  • Green Hydrogen
  • Climate aware farming practices
  • Activities in our area
  • The role of clouds
  • The usefulness of kelp.

When we gather, there are lots of questions raised. Maybe you'll have some too."

The Role of Seaweed in Mitigating Climate Change


Seaweed and moo noos (Cattle)

Did you know – methane emissions from livestock make up about 15% of global greenhouse gas emissions.

Did you know – that a cow produces on average as much gas emissions as one car.

Did you know – that CSIRO in Australia claims that methane stays in the atmosphere for about nine years, a far shorter period than carbon dioxide, however methane's global warming potential is “86 times higher than carbon dioxide when averaged over 20 years….”.

Did you know – the CSIRO has developed a seaweed product that reduces greenhouse gases produced by cattle and has won a $1M international prize for doing so.

Did you know – that this seaweed product slashes the amount of greenhouse gases cattle ‘burp’ and ‘fart’ (mainly burping) into the atmosphere.

It is claimed that when this product is added to cattle feed, the product, which contains Australian “super seaweed” Asparagopsis, virtually eliminates methane from the animals bodily emissions. Also it is claimed that the potential for the product to reduce the world’s greenhouse gas footprint, if commercialised, was massive.

Watch this space for developments in the cattle industry.

Some other seaweed benefits

We are all familiar with the role forests play when it comes to providing a sustainable source of food, energy and raw materials, and locking away CO2 emissions. But perhaps we are less knowledgeable about the potential of forests of seaweed growing in the oceans.

Did you know – seaweed plays a crucial role in the ocean’s ability to absorb greenhouse gases and is grown around the world.

Did you know – seaweed is better at absorbing CO2 than trees are.

Did you know – seaweed is considered a high valued source of protein for humans and livestock.

A type of seaweed known as kelp, is being developed for its nutritional value and its ability to absorb and knock away huge quantities of carbon dioxide (CO2). Seaweed, in the oceans, helps to de-acidify the water and absorb CO2 more effectively than trees. It also improves water quality by extracting harmful nutrients such as nitrogen from the sea.

Seaweed / Kelp - what’s the difference?

Seaweed is a plant growing in the sea, especially marine algae; unlike land plants, it does not have roots, stems, leaves and flowers; and may be green, brown or red; it grows on the seashore, in salt-marshes, in brackish water or submerged in the ocean.

Kelp is any large, brown, cold water seaweed of the family Laminariaceae, used as a food and in various manufacturing processes, a bed or mass of such seaweeds.

. How do things get done at U3A Port Phillip?

U3A Port Phillip is run totally by Volunteers.  Have you ever wondered what do they do behind the scenes?

In this article, we take you into the amazing world of how your Courses are scheduled.

To schedule a Course, we need two things: a Tutor to present a Course and a place to run the Course, either physical or virtual.

For Courses that run all year, Tutors propose the Course they wish to run in October/November of the preceding year.  For Courses that run for a specific period such as one or two Terms, Tutors propose their Course approximately one month in advance.

In their proposals, Tutors also request a place to run their Course, for example:

  • Online
  • A City of Port Phillip venue, such as Mary Kehoe Hall, South Melbourne Community Centre Hall 1, Sol Green Community Centre Hall, Middle Park Community Centre Hall
  • If a Tutor is organising the venue in which the Course will run, the Tutor advises the location such as a private home or a bowling club or a park

For Online Courses, the U3APP IT group purchases the appropriate number of Zoom accounts to enable multiple concurrent Online Courses each day, including suitable gaps between Courses using the same account.

For City of Port Phillip venues, U3APP must apply to CoPP on an annual basis to hire specific rooms for specific dates over the financial year July to June.  In 2021, applications for room hire are submitted during a 2 week time period at the start of May.  After the application period closes, CoPP evaluates the applications, determines the successful applicants and advises the results in June.  Due to the reduction of venues available for hire and capacity limits imposed by COVID requirements, CoPP cannot guarantee that requested days, times and venues will be available.

Once we know the Courses which Tutors wish to give and the venues we can use, then the Course Coordination team, in particular Ann Gibson, can start scheduling.  Face to face Courses requirements, such as a particular venue, a particular day and time, a particular room size, are matched against the specific rooms available.   COVID requirements impose additional restrictions on scheduling face to face Courses, such as longer gaps between Courses in the same room and staggered start times between courses in different rooms in the same venue.  To achieve a workable Course Schedule requires cooperative consultations and a team effort between the Tutors and Course Coordination.  In practice, the fluidity of available face to face rooms caused by COVID restrictions has necessitated continuous consultations since October 2020.
