'Coding' is currently in the news, with a push to have more young people learn how to code to empower them to create sites, programs and apps. Our July session considered an earlier period in which coding - and code breaking - became an imperative, the period in which the impact of the coding based 'enigma' machine and the development of a machine to counter this by Dr Alan Turing and his team at Bletchley Park during World War II. Instead of a talk we watched the movie 'The Imitation Game' based on the Enigma machine and Dr Alan Turing's involvement with it. We all felt it was worth viewing, It is available on loan from the Benalla Library. Some reading: 'The Enigma Machine - How Alan Turing Helped to Break the Unbreakable Nazi Code'.

This month's talk moved back to IT, but this time with a family history focus. A TED talk by Al Jacobs on a major geneological project set the scene for the day's topic 'Family History, A Tech Savvy Perspective'. Before beginning her own presentation, Bev asked class members who had worked on their family trees to talk about the ways in which they conducted their research and for a highlight in their quest. Methods varied from the use of telephones and postal services 30 years ago to state of the art internet based programs today. High points included finding out the true story behind an 'unknown' grandfather and a range of exciting break throughs. Bev then presented on using the internet in her quest to resolve family mysteries and secrets. Lots of contributions were made by class members well versed in family history research, their was further sharing of experiences over the coffee break, and a number of people commented that they felt inspired to begin or resume work on their family tree. We finished with Les leading a short activity on the untangling the mystery of how shoelaces come untied which was thoughtprovoking & engaging - and of particular appeal to our engineers The Rustik discussion group made the transition to the new time to avoid a clash with Wine Appreciation, meeting on the fourth Thursday at 3 pm for coffee and discussion of topics of interest. Topics included the Grattan report into the difficulties facing the National Energy Marketing Organisation with the currently unworkable arrangements of state governments doing their own thing and the commonwealth making ad hoc decisions about building more taxpayer funded generating capacity all with no coherent policy. Peter shared an interesting article on tyre pressure monitoring which would be very useful for those with expensive tyres as Les found out recently. (You can also check out their reports on the 'Tech Savvies' page) Funding has been approved for two short courses 'Facebook for Mentors'. The first two session court course targets the mentors for Tech Savvy Beginners, but there is to be a second group which interested Tech Savvy Talks and Plus participants who are not mentors can put their names down for.
The Tech Savvy Talks group has been working through our list of topics for Semester I, moving on in May to looking at ‘alternatives to baseload energy’. Brian demonstrated his models of Sterling engines to start the conversation and Richard Morton from Sunreal has been booked for a future session.
We considered news of an educational initiative in our region introducing children to technological innovations including 3D printing, following this by viewing a Ted Talk by Mitch Resnick of ‘Scratch’ titled ‘Let’s Teach Kids to Code’.
Les Rodgers then provided an informative update on the rolling out of the NBN in Benalla. Les could give us some indication from the NBN website as to whether we might receive NBN to the kerb. It appears seems some areas of Benalla will receive this (preferable) option because of the age of existing conduits. Les did stress that the information appears to be changing.
Clare, Peter, David and Les met for coffee and conversation at Rustik on Wednesday 26th April. Les facilitated a discussion about LTE Broadcasting which early adopter Telstra has been trialling and which will be rolled out nation wide next year. It is basically aimed at high quality video or multimedia services for mobile devices capable of receiving 4G LTE-B transmissions although obviously the content could be cast to a TV receiver from mobiles using a Chromecast or similar device. The content to be provided is not fully decided but could range from sporting events to first release movies. Both Telstra and Optus appear to be looking ahead for new products and services to replace existing ones in life after NBN. Please note - The coffee catch up date has changed from the fourth Wednesday to 10.30 am on the fourth Thursday at 3 pm at Rustik to enable tech savvy wine afficionados to attend Wine Appreciation activities as a less cerebral endeavour!
Peter Simpson began our April session introducing an article on DRED (Demand Response Enable Device). DRED is an energy demand management device which enables energy suppliers to switch off or reduce the amount of power drawn by devices such as domestic air conditioners at times of peak demand in summer. Brent Bailey then spoke about a visit to Canberra during which he attended a thought provoking seminar on Solar Energy on behalf of Cathy McGowan. Bev raised the ABC’s Law report about legal dilemmas arising from 3D printing and news of 94 year old inventor of the lithium battery John Goodenough's recent release of a new battery. Our TED talk for the month explored the ongoing development of ‘a plane you can drive’ - the ‘Terrafugia Transition’- a ‘light sport roadable aeroplane’. The theme of alternative vehicles continued, with Brent introducing us to the electric paddock vehicle he and Pauline researched, imported, assembled and now use on their 170 acre farm. We ventured to the car park behind Aldi to inspect and discuss Brent’s vehicle, some of us taking up Brent’s offer of a test drive (see photos in previous post). It proved quite zippy and responsive to drive – it’s also quiet, which Brent described as a great advantage as it doesn’t disturb the animals on the farm. Next coffee meeting will be at 10.30 am at Rustik Cafe on Wednesday 26th April. For more information, contact Les Rodgers on 5762 7600
A Plane You Can Drive? Ted Talk for Tech Savvy Talks this morning! We're also going to chat about legal dilemmas arising from 3D printing from a recent 'Law Report' and 94 year old inventor of the lithium battery John Goodenough's recent release of a new battery. And then - our guest speaker, class member Brent, is going to introduce and demonstrate his electric farm vehicle! This month Les Rodgers presented another informative on session on the Internet of Things (Iota), commencing with the Ted Talk ‘How Arduino is open-sourcing imagination’ by Massimo Baozi (Refer post below). Following the coffee break, the group headed to Terry Dillon’s home where Terry demonstrated lots of examples of connectivity, including Chrome casting. At least one person has borrowed a Chromecast to try. Terry, Brent, Brian, Wende, Jan. Les and Peter exploring examples of connectivity at Terry’s.
The alternate fortnight discussion group at Rustic Café facilitated by Les grew this month from three to five members. Les reports that he, David, Len, Peter and Brent “talked about the requirement of the NBN for a VDSL2 modem which would likely be provided by an ISP, who may also provide a wifi router as part of that. Experience suggests the wifi router provided by the ISP may not meet everyone’s needs for speed and security. We explored some of the offerings available and found the Google wifi particularly interesting in terms of security and adequate speed (throughput around 100 mb/s) as well as ease of setup. Google wifi was released overseas late last year and is much in demand. It is not yet available in Australia. Another interesting one not yet available is the F-Secure SENSE. It is to be released around the middle of this year. Both Google and the SENSE need to be continuously on line for updating of security patches and offer protection against a wide range of possible intrusions. Google updating is free while SENSE will cost $8 per month. Both of these claim to protect home networks including any IoT things which are very vulnerable in some cases”. At our next regular session on the Wednesday 12th April at 10 am in W4 Brent will be discussing and demonstrating the electric farm vehicle which he assembled, powers with solar power and uses on his farm – perhaps you’ll see us trialling it in the car park behind Aldi! Our February session began with a Ted Talk by inspirational lawyer and academic Professor Ron McCallum ‘How Technology Taught Me to Read’ . Ron’s presentation particularly resonated with class member Peter Simpson. Because Peter is legally blind, Peter has utilized many of the computer based adaptive technologies described by Ron. Peter shared memories of playing ‘blind cricket’ with Ron as a teenager using a cane ball which contained bottle tops and metal wickets which resounded loundly when hit. This discussion was followed by a most informative presentation by Les Rodgers on ‘The Internet of Things’(IoT). The group agreed to continue our practice of commencing with a TED talk on a stimulating topic followed by a guest presentation and suggested future talks on topics including Brent’s Electric Paddock Vehicle; an Update on the NBN Rollout; Facebook and Security; and Options for Baseload and Renewables. Towards the end of the month Les piloted our (optional) discussion group at Rustik café . Les reported that discussion ranged across many topics including high frequency radio and ‘ham’ radio. “We also learned something about life on Willis Island. A pleasant hour quickly passed by three people with similar interests”.
Our next meeting on Wednesday 8th February will incorporate a visit to the home of Terry Dillon to see examples of IoT connectivity, including the use of Chromecasting. Our presentation this morning is by Les Rodgers - the topic, the Internet of Things. We decided to start with a TED talk, not on the internet of things, but on a topic relating strongly to the themes of 'accessibility' and 'inclusion' by inspirational lawyer and academic, Ron McCallum. Post script: During the session it was agreed that the alternate fortnight 'Tech Savvies' discussion group led by Les Rodgers would be held at Rustik cafe on Wednesday 22nd February (4th Wednesday) from 10.30 to 12 midday.
More news about the meeting and planning for upcoming meetings in the next Newsletter and web page report. Photographs: Terry Dillon Our November session featured Bill Parris’s collection of watches. Bill began to buy quirky, inexpensive watches after a valuable watch he received for 30 years of service disappeared. We had great fun looking at Bill’s Rolex, Gucci and other brand-named imitations. Bill also provided an overview of changing watch making technology over time and intrigued us with his collection of watch maker’s repair tools bought inexpensively over the internet. Next step for Bill – a presentation at ‘Collectors’!
Tech Savvy has been renamed ‘Tech Savvy Talks’ in 2017 to distinguish it from other Tech Savvy groups. Monthly sessions will continue to commence with a TED talk on a topic of interest followed by a guest presentation and then time for our ‘Mentors’ and ‘Tech Savvies’ working groups to meet. In 2017 ‘Mentors’ will support the Tech Savvy Beginners course, while the ‘Tech Savvies’ reading group will meet at a local cafe on the alternative fortnight to discuss the Internet of things (IoT) and other developments in computer and communications technology . Dramatic film taken from the cockpit of a competing glider racing another at up to 250km/hr during a gliding competition in Chile began our October session, fitting in well with ‘The Sky’s the Limit’ theme of this year’s Benalla Festival in the lead up to the World Gliding Championships in January. Guest speaker, glider pilot Tim Shirley, gave a fascinating presentation on changes over time in the devices used to track the position and performance of gliders, particularly during competitions. Since the advent of GPS it seems that the capacity for occasionally corrupt practices during competitions has been virtually eliminated!
Certainly the gliders coming to Benalla in January - which carry price tags from about $150,000 to $500,000 - will have the latest tracking equipment. Perhaps more importantly they are much lighter than previously because they are made of kevlar and carbon fibre and travel 50 metres forward while only descending one metre. Tim’s session clearly provided rich ground for reminiscing by those with past experience of gliding. It also provided us all with a more informed base on which to understand the experiences of those who will be flying over Benalla in January. During question time Tim, an experienced competitor, was asked if he would be gliding during the competition. He jokingly set us straight saying there are teams of six pilots from each country, and he’s not exactly the Michael Schumacher of Australian Gliding. An intriguing answer resulted from the question ‘Why have so many of the advances in gliding technology taken place in Germany’? It seems that after World War I the Treaty of Versailles contained provisions restricting the production of powered aircraft in Germany. The result - the attention of German aviators changed direction - to gliding. Our final session will be on November 9th when Bill Parris will introduce his extensive watch collection as part of a ‘Show and Tell’ session in which we will all bring along an item or two which demonstrate changes in technology over time. This will be followed by time for working groups ‘Tech Savvies’ to discuss incorporating the Internet of Things in next year’s sessions and ‘Mentors’ to begin planning the Tech Savvy Drop In for 2017. Another thought provoking TED talk, this time ‘What can save the rainforest? Your used cell phone’, set the scene for our September session. Class member Les Rodgers followed with a presentation highlighting the main changes in communications technologies (including broadcasting) and their impact during his career as an engineer. Originally from Queensland, Les spent most of his working life with Telstra and its forebears, apart from a period with the Weapons Research Establishment in South Australia. His working life began at the time of switchboard technology and included time in New Guinea; involvement with rocket launches at Woomera; dealing with governments at high levels while national manager of projects including the spread of television transmission to country areas and broadband to rural Queensland ; the replacement of the television transmitter in Hobart; and speaking at a Senate Estimates Committee leading to a mention in Hansard. What a rich career – thank you for sharing your journey with us Les. Next month, IT specialist Tim Shirley will continue the theme of changes over time in technology, presenting on changes over time in the Gliding Industry, a very pertinent topic with the World Gliding Championships being held in Benalla in just a few months.
At our final meeting in November, Bill Parris will lead a ‘Show and Tell’ session in which we will all bring along an item or two which demonstrate changes in the technology over time. Bill is going to bring along his extensive watch collection, while the rest of us are thinking deeply about just what we might bring along. Just a reminder about our meeting on Wednesday morning and to let you know that we have a change of speaker. Tim Shirley, who was to present on changes in IT over time in the gliding industry, will now present in October. Les Rodgers, who was to present in October, has agreed to present a month earlier. Thanks Les!
Les, originally from Queensland, spent most of his working life with Telstra and its forebears, apart from a period with the Weapons Research Establishment in South Australia. He has worked across a wide range of communications technologies, including broadcasting. Les is to talk about his journey through the communications world, highlighting the main changes in technology and their impact. See you on Wednesday morning! We met on the morning of August 10th, so the apparent problems with suspected hacking and inability to cope of the computers at the ABS on census night the night before were hot topics. It seemed relevant to choose another TED talk to begin the session, this time The Economist’s Kenneth Cukier’s consideration of whether ‘Big Data is Better Data’, selected from Computer World’s 10 TED talks for Techies. Tech Savvy member Peter Simpson then engaged us in a fascinating presentation on changing technology in the television industry, drawing upon his extremely rich working life as a television engineer. Peter’s informative presentation also provided an unexpected and memorable opportunity for us to reminisce as we had all been players, if at the other end of the television screen, in these changes over time. A collector and afficionado of television clips from the past, Peter’s presentation included clips from the Mickey Mouse Club, Happy Hammond’s theme ‘Happy Days are here again’ and more! After a late coffee break we broke into groups, with the Mentors checking out the latest handout on the ‘Google Apps’ course while the ‘Tech Savvies’ working group talked about topics for further investigation.
Our September meeting will continue the theme of changes over time in technology, with IT specialist Tim Shirley presenting on changes over time in the Gliding Industry. Our August session will feature a presentation by Peter Simpson drawing on his experience and understanding of changes over time in technology in the world of the television engineer. With last night Census night, the debate about impacts on privacy of including our names on the census form, and the hacking attacks on the ABS computer system, the following video from the Computer World series we started last year seems pertinent. "Kenneth Cukier: Big data is better data As data editor for The Economist and coauthor of Big Data: A Revolution That Will Transform How We Live, Work, and Think, Kenneth Cukier has spent years immersed in big data, machine learning and the impact both have had on society. "More data doesn't just let us see more," he says in his talk. "More data allows us to see new. It allows us to see better. It allows us to see different."The heart of Cukier's talk focuses on machine learning algorithms, from voice recognition and self-driving cars to identifying the most common signs of breast cancer, all of which are made possible by a mind-boggling amount of data. But along with his clear enthusiasm for big data and intelligent machines, he sounds a note of caution: "In the big data age, the challenge will be safeguarding free will, moral choice, human volition, human agency." Like fire, he says, big data is a powerful tool -- one that, if we're not careful, will burn us." http://www.computerworld.com/article/2975866/emerging-technology/10-ted-talks-for-techies.html#slide7 There have been some changes to dates for the Google Apps class which will allow our members who attend Let's Talk Books to participate. Here is the revised timetable, just in case you don't get it in class.
Our July meeting began with a challenge for more members of the group to set up Twitter accounts and follow up news concerning recent set backs to the Google Glass project. Rich discussion followed viewing of a thought provoking and pertinent TED talk titled ‘How to upgrade democracy for the internet era’. Last month’s theme of digital photography then continued with Terry updating us on new applications, including Photosynth.
After the coffee break we broke into groups. The Mentors working group tabled a spreadsheet prepared by Bev and Marg W reviewing the Tech Savvy Drop In group participation during first Semester, then allocated themes to presenters for Drop In sessions to mid September. The Tech Savvies group talked about topics including malware; developments in virtual reality; downloading YouTube files (Firefox does this easily but Peter is going to put an alternative in the Dropbox Techsavvies folder) and discussed the news that Microsoft are no longer forcing Windows 10 on people after losing a court case costing $10,000 in the small claims court. Les has been following up Ian’s suggestion of using ‘Malwarebytes’ to resolve malware problems and will report back about this at a future Tech Savvy Meeting. At our August meeting Peter Simpson will explore technological changes over time in the television industry, drawing upon his rich and extensive working life as a television engineer. A video based catch up on the development of ‘Google Glass’ set the scene for our June session. Terry Dillon then discussed Windows 10 (which he considers it among Microsoft’s best releases to date) and the possibilities offered by free and accessible programs/apps to produce a high quality photographs.
After the coffee break we broke into ‘Tech Savvies’ and ‘Mentors’ working groups. ‘Tech Savvies’ continued to share news and reading on current issues in IT – with Les later adding three articles to our Dropbox folder – “The Death of Firefox”, “Aging at Home 2 – Some Tech to Watch Over Me” and an article which led to discussion about Samsung’s decision not to install Windows 10. ‘Mentors’ had a productive catch up about the ‘Drop In’ and discussed mid year as an appropriate time to review the program, either by questionnaire or personal contact. Areas suggested for review include attendance patterns and the level of understanding and ‘IT context’ at home (eg. with/without WiFi, in ‘blackspot’) of people who begin the Drop In. Geraldine demonstrated a WiFi Network-ing device that sits beside her iPad which has increased her capacity to use her iPad at home, which is in a ‘blackspot’. Margaret’s report on these discussions has been added to the Mentors working group’s web page. At our next session Terry Dillon will conclude his presentation on features of Windows 10 and programs/apps which produce high quality digital photography. Windows 10 has now been installed on the W4 computer! The worldwide U3A movement incorporates the concept of reciprocal lifelong learning, with members as far as possible being both teachers and learners. This was very positively demonstrated at Tech Savvy’s May session when photography buff Ken Jenkins gave a most informative presentation on developing the understanding required to make an informed choice when buying a camera. Ken drew upon on his extensive collection of cameras and accessories when discussing cameras from today's mobile phone cameras through to the cameras, lenses and accessories used by keen amateur and professional photographer After the break the ‘Techsavvies’ working group discussed topics including 'screens and sleep deprivation' and the recurring question of whether to install Windows 10. Apart from behavioural changes required to restore healthy sleep patterns, there are apps for shifting the colour temperature of screens away from the blue end towards a warmer colour and reducing the intensity of the blue light. One manufacturer produces a ‘low blue light monitor’ for pcs. Things to watch out for with Windows 10 include making sure whether you need a 32 bit version or 64 bit version. A group of 'Mentors' and others worked with Terry Dillon on further developing understanding & skills in using Drop Box.
During the session Bev presented a ‘quarterly briefing’ on the development of the Tech Savvy Drop In program and the Google Apps ten session course commencing in mid September. Terry Dillon will present on photography related computer skills as part of our June session. Tech Savvy will continue its monthly sessions as planned in Semester II. Our April session began with a thought provoking video segment ‘The Death of the ATM?’ followed by an informative presentation on Smart Devices by group member Terry Dillon. Terry focused on ‘ICE’, Dropbox and the Dashlane password manager and is now planning practical sessions in using Dropbox and printing from the Cloud. Terry’s website page on ‘Smart Devices’ can be found at http://teedee.com.au/devices/.
Mingling and shared problem solving during the coffee break was followed by Bev’s progress report on the Tech Savvy Drop In & the Tech Savvies working group. During our end of session ‘Q&A’ we learnt that a successful outcome when using USB and cigarette lighter connections in cars for recharging devices depends on matching the power available through the USB connection with the power requirements of the device being charged. Another Q&A question concerned the current advisability of installing Windows 10. Most group members who have installed Windows 10 reported positively. Older versions of Office programs such as Excel may need to be updated for files to open. While updatable subscriptions to Office 365 are available, concern was expressed that taking up such subscriptions may be problematic for older people on limited incomes. Upcoming sessions will feature a presentation by tech savvy photography buff Ken Jenkins on cameras and the photography related programs he uses, to be followed up later by a complementary session on digital photography by Terry Dillon. Our guest spot for March featured Tech Savvy member Ian McLeod who presented an overview of freely available entertainment sites on the internet.
From www.radiotunes.com we listened to country and classical guitar music; later comparing this site to the music play lists available on YouTube. Ian explained that streamed audio files such as those from radiotunes.com use less memory than youtube files which feature both video and audio files. Ian then demonstrated links on www.tunein.com using Edinburgh radio stations amongst others, adding that listening to Scottish radio helps him to keep his accent! Ian explained that YouTube has effectively replaced Wikipedia as his online encyclopedia, using examples drawn from the class to demonstrate its versatility in resolving problems. ‘Free Movies’ and ‘Streamed Movies’ on YouTube; the SBS On Demand movie site and the free trial version of NetFlix were all demonstrated and the use of VPN for downloading of movies briefly discussed. Class member ‘entertainment’ suggestions included ‘Spotify’, which has scope for creating playlists; watching full length classic movies such as ‘Grapes of Wrath’ or historic film footage such as Rachmaninoff playing Rachmaninoff on YouTube; subscribing to BigPond movies and entertainment packages such as ‘Stan’ and i-View. After the break the ‘Mentors’ working group shared ideas for upcoming Tech Savvy Drop In sessions; while ‘Bloggers’ and the ‘Tech Savvies’ discussed aims and directions for their activities for the rest of the year. April’s presenter, Terry Dillon, will be discussing extending our phone/tablet skills. Topics which Terry will be discussing are accessible for preview on http://teedee.com.au/devices. 27 ‘Tech Savvy’members met on Wednesday 10th February in W4. Guest speaker David Gipp from the Telstra Shop at Stolz spoke of the services they provide and responded to a wide range of questions from class members. Of particular interest - the 2G and 3G networks will be phased out and replaced with a new 4G network by the 1st December this year and the NBN should be through Benalla in 2017. The problem of blackspots around and out of town was raised with David by a number of class members. Ringing Cathy McGowan’s office to complain was discussed as a strategy which could assist evidence gathering which may lead to change.
Before the coffee break members introduced themselves and spoke of their interest in coming to Tech Savvy, providing a fertile base for connecting up with others during the break. After the break the group was briefed about planning for the new Tech Savvy Drop In. Dilemmas facing the planning group in managing the disparate learning needs of over 50 enrollees were discussed. A second time slot was considered and recommended as was dividing the Drop In group timeslots between Apple and Microsoft/Android users. Input was also sought on the idea of using targeted ‘packages’ to provide a theme for part of each Drop In session and for individual/small group mentoring. It was noted that with the high demand for the Tech Savvy Drop In sessions there will be a greater than expected demand for mentors - and that the mentors are likely to need mentoring too! Next Tech Savvy session Ian McLeod will present ‘Entertainment II’ (an entertainment related ‘package’ for the reasonably confident internet user) followed up by ‘bloggers’, ‘mentors’ and ‘tech heads’ working group meetings. 2016 – The Year of Digital Inclusion’ – in Victoria and for our Tech Savvy group.
Guest Speaker – David from Telstra Shop at Stolz, has taken up our invitation to speak about the services they offer and to give us some insight into the sorts of issues which older people come to see them about. Digital Inclusion: In late 2015 the Mentors working group of ‘Tech Savvy’ developed the idea of offering a ‘Tech Savvy Drop In’ to support members with e-learning needs. The mentors group has met a number of times over the break, developing skills in using iPads (See ‘Take that Siri! in last post), an assessment process for incoming Drop In members, a Tech Savvy Drop In website (under construction); and locating and trialling user friendly resources to draw upon in mentoring others. The Mentors group suspected there would be a large unment demand for support. This was confirmed during the enrolment process, with 50+ enrolments. We suspect, and ‘early polling’ indicates, there is a also wide variation in needs, so we have had to come up with some ways of managing both numbers & needs. Tech Savvy Suggested Response 1 –builds upon wisdom gained from our Tech Savvy group – there are Microsoft/Android Users and Apple Users! Early polling of Tech Savvy Drop In enrollees suggests there is a roughly a half in half division. Suggestion: to timetable two Drop In groups instead of one – one for Microsoft/Android users/mentors; another for Apple users/mentors. |
