Replace New Year's Eve Fireworks with an App

There have been some calls for new year's eve fireworks to be cancelled in Australia, due to bush-fires. Perhaps they could be replaced, at least in part, by spectators' smart phones. The idea would be to have each person hold up their phone, which would display part of a coordinated pattern. This would be similar top the effect where those in a stadium hold up colored cards on cue, but could form a much faster changing, more vibrant pattern. This could supplement laser light shows and displays projected on buildings. This would also turn people from spectators, into active participants in the show, as well as avoiding setting off pyrotechnics during a total fire ban.

Carryon Backpack for Travel

Caribee Sky-Master
Carry On Bag
For a recent trip to Singapore and Indonesia, I purchased a Caribee Sky-Master 40L Carry On Bag, which worked very well. I had booked some budget airline flights, which did not include checked baggage. My old wheeled bag was heavy, and took up a considerable part of the carry-on allowance. So I looked for a light bag, carry-on size, which also had backpack straps. 

There is a bewildering rage of carry-on bags. I wanted one which did not have wheels, or a frame, to save weight, and  looked more like a bag, than a backpack. Also I wanted one which opened up flat, and ideally, had compartments. With many backpacks you have to stuff clothes in through a narrow opening in the top.

First  I purchased a Cotton On Foldable Cabin Bag. This zipps down the middle and opes to reveal two zipped mesh compartments, making it easy to pack. It weighs very little, however it had no backpack straps (just a shoulder strap). Also it is made entirely of fabric, so does not retain its shape, making it more difficult to carry.

Shorty before my trip I purchased the Caribee Sky-Master. Like the Cotton On bag, this zips open and has two mesh covered compartments. One compartment is slightly larger and has compression straps. It also has backpack straps, and a foam plastic back-plate which keeps it in shape. The backpack straps can be concealed in a zippered compartment, and are very comfortable in use. There is a carry handle on one end and on the side, allowing it to be carried as a small suitcase. There is an outer zippered compartment for small items, but I found that I tended to open it too far and they fell out.

While luggage sellers make much of conforming to airline carry-on bag restrictions, when I cam to pack my bag I found that weight, was the limiting factor. My first flight, from Sydney to Singapore, had a limit of 10 kg, which I was able to meet, but the second flight, to Yogyakarta, was limited to 7kg. If you fill a carry-on size bag it is very difficult to get it under 7 kg. At this stage of my travel, my bag had increased to 12 kg, so I purchased extra checked luggage allowance. By the time of my third flight, the bag had got to 20 kg (with all the shopping, and fortunately I had checked baggage with the last ticket. 

In the dining car
Even if you do not carry your bag on the aircraft, a carry-on size bag has advantages, in terms of freedom of movement. I was easily able to meet the Yogyakarta to Jakarta Train limit of 20 kg. Also one relatively small bag is much easier to get on and off ground transport, such as a Yogyakarta local bus. The extreme test of this was on a commuter train at rush hour in Jakarta.

ps: Caribee might consider making this bag simpler and lighter. The backpack straps could be made removable (as the shoulder strap is). There would then be no need for a zipped compartment on the back to hold the straps. The smaller compartment on the front could be given a lip, so items don't fall out when it is opened, or this could be omitted (this would make security much easier, as the bag with then have just one zip).

Wireless Active Noise-Cancelling Headphones for Travelling

Audio-Technica ATH-ANC500BT
Noise-Cancelling Headphones
For a recent trip, to Singapore and Indonesia, I purchased Audio-Technica ATH-ANC500BT Wireless Active Noise-Cancelling Headphones. These are reasonably priced, over the ear headphones, which cut down the roar of an aircraft's engines. They worked well on three planes and a long distance train. 

This is my first pair of cordless headphones and I found it a relief not to wake up on an aircraft entangled in wires. The batteries last long enough for the flight from Sydney to Singapore. The controls are simple: one switch turns on both Bluetooth and the noise reduction function (you don't have a choice of one or the other). There are volume up, down and pause buttons.

On the Yogyakarta
to Jakarta Train
The audio cable with 3.5mm plugs (provided) worked fine plugged into the aircraft system. With the cable the headphones will worked without power, but then without noise reduction. The Bluetooth function worked well.

I did wish the headphones were a little more compact. The ear-cups rotate so they can be laid flat, but they do not hinge in, so are still quite large. I bought the blue, rather than black model, so they would be easier to see in a dark aircraft, but they could do with some bright highlights as they are still hard to see (but does makes them unobtrusive). That said, I have no regrets with this purchase.

Mount Merapi

Mount Merapi is an active volcano near the Indonesian city of Yogyakarta. This photo was taken from the balcony of a hotel downtown, during the TALE 2019 conference. In 2006 I arranged for the Australian Computer Society to fund Indonesia students to work on adapting the Sahana open source disaster management software if needed for an expected eruption of Merapi. Fortunately this did not happen.

Skytrain Jakarta Airport

Skytrain (from Wikipedia)
Arrived at the new Terminal 3 of Soekarno–Hatta International Airport's new Terminal 3, after a ride on the free Skytrain, from the Railink station. This is a small rubber tired shuttle on an elevated track between the three terminals. It is designed to be automated, but there was a driver perched on a stool at front, with just a tape separating them from passengers.This was my fourth, and hopefully last, train ride for the day.

Terminal 3 is very new and very large: the shuttle stopped in front of what I thought was the front of the building, but when I looked up there was a roof high above us. Facilities are still be installed: the "street food" so far consists of burgers and pizza. There are free showers, but I was not offered a towel, or soap.

On the Jakarta Airport Train

Greetings from the Jakarta airport train ("Railink") to Soekarno–Hatta International Airport. I took the train from Yogyakarta after the IEEE TALE 2019 engineering education conference, then one stop on a crowded commuter train to transfer to the airport express at Manggarai. The only difficulty was that the station is being rebuilt, so to get from the old commuter platform to the shiny new airport one, I had to balance along the edge of the platform, with busy commuters coming the other way, then walk cross the tracks. I then went up an escalator into a different world of space, and helpful staff. The train appears to have more staff than passengers, the conductor explaining Friday is the peak time. Also the warned me that at Duri the train changes direction. One improvement would be to have the train display the next destination: currently the display tells you the temperature and the speed of the train, which are not as important as where to get off.

Bright lights of Yogyakarta

Bright lights of Yogyakarta
I took this photo from a pedestrian overpass in Yogyakarta, last night. It was late and so the street was now as busy as during the day. I am here for the IEEE TALE 2019 engineering education conference. I arrived during a downpour, and foolishly decided to catch the local bus from the airport, rather than take a taxi, or wait for the rain to stop. Just finished drying out.

Gov 2.0 Taskforce: Annual "unparliament" at Old Parliament House?

Asia Pacific Hall at the SFU Morris J. Wosk Centre for Dialogue
SFU Asia Pacific Hall
At Gov 2.0 Taskforce: Ten Years On,  we are back from work-shopping actions to progress. Mine was to propose an annual "unparliament" be held at Old Parliament House.

The Simon Fraser University  Centre for Dialogue has a purpose designed circular room, the Asia Pacific Hall, for fostering constructive discussion.

OPH Senate Chamber
In contrast, Australia's Old Parliament House has two chambers with rows of seats facing each other, designed for an adversarial approach where there is a government, and opposition (with a small amount of room for others on the "cross bench). However, the old building hardware could be updated, with some mobile devices and applicaions, to allow for techniques such as deliberative democracy. In effect we would be upgrading democracy with some teach.

Gov 2.0 Taskforce: Open is Expensive, Not Just Free

At Gov 2.0 Taskforce: Ten Years On, one of the un-conference presentations was on "Open is Expensive, Not Just Free". The essence of this seemed to be pointing out that open access initiatives are usually supported by unpaid volunteers. The implication is that these initiatives can't be maintain, because we can't expect people to keep working for free. I suggest the start-up community has an answer to this. There are models by which people can work on free open products, but still make money from them. One example is "social enterprises". Also start-up centers, such as the Canberra Innovation Network (CBRIN), train people how to build a business case, which includes who is going to pay, and also trains people to ask for money. Also there is The Mill House, which specializes in social enterprises.

There is a live stream and online questions are accepted. From the

Gov 2.0 Taskforce: Recommendations

Minister's Office, Old Parliament House
At Gov 2.0 Taskforce: Ten Years On, we broke into groups to look at the "Engage: getting on with Government 2.0" report recommendations.  There is a live stream and online questions are accepted. From the two groups I talked to Recommendation 4: Encourage public servants to engage online , has had mixed results. There are now many ways for government to collect citizens views online. However, public servants are, if anything, more constrained in doing anything with the results of the consultation. The digital public facing system is not well interfaced to the old analogue public service hierarchy. There is then a widening air-gap between the public service and the political level of government. 

To me this problem of getting anything done in government sounded an old problem. As a public servant,I had to occasionally work around the official processes to get anything done. This was usually with official approval. For these purposes links to academia and the professions are useful. Unfortunately in the Internet age it is very much more difficult to have an off the record, or "other hat" discussion. To that end I have added "Teaching Gov 2.0 to Government" to the list of topics for discussion.

A recent example is that ANU will run the Cyber Bootcamp Project for the Department of Foreign Affairs and Trade. Such courses provide a way for government employees from across governments to have a relatively free discussion. Students can explore ideas as students, then work out how the outcomes can be put to their organizations as initiatives. This also happens in professional bodies, and standards committees.

Gov 2.0 Taskforce: Ten Years Done

Pia Andrews
At Gov 2.0 Taskforce: Ten Years On, Pia Andrews gave an upbeat summary of achievements.Pia  pointed out that, for example, the Australian Federal Government adopted an open access creative commons license for its documents, and state agencies adopted more online engagement. However, she suggested more recently this engagement has changed to consultation, rather than encouraging more active citizens participation. I have noticed this, being invited to what are characterized as "co-design" workshops with government, but which are really old fashioned, customer focus groups, dressed up with some hashtags. There is a live stream and online questions are accepted.

Nicholas Gruen,
CEO, Lateral Economics
At Gov 2.0 Taskforce: Ten Years On, Nicholas Gruen is reflecting on the original intent of the Taskforce and what happened. There is a live stream and online questions are accepted. He showed some "historical artifacts" slides, which showed the excitement and potential of Gov 2.0 ten years ago. One aspect was how outsiders, not from government, could have input. The widespread interest in the report "Engage: getting on with Government 2.0", was its translation into Korean. However DR. Gruen's summary was "We got our recommendations accepted, but then they were not implemented".

Gov 2.0 Taskforce: Ten Years On

Greetings from Old Parliament House in Canberra, where the Director is opening Gov 2.0 Taskforce: Ten Years On. I will be blogging on it throughout the day. There is a live stream and online questions are accepted. My old posts from ten years ago are at gov2taskforce. Here is the official announcement of the event:
"It has been 10 years since the Gov 2.0 Taskforce handed down it's report. Those were optimistic days, so let's review & plan next steps. ...

About this Event

A few folk who were involved or contributors to the Gov 2.0 Taskforce (2009) thought it might be useful to reflect on the 10 years since the Report was delivered. Those were optimistic days and a strong community formed around the activities and engagement from the Taskforce. The Report recommendations were accepted almost entirely by the Government Response, so 10 years on, how well was the intent and vision of the Report realised, and what do we need to do next?
Our sincere thanks to the Museum for Australian Democracy (and Democracy 2025) for being the venue sponsor and supporter for the event. The event will be hosted at Old Parliament House, the perfect setting!
Thanks also to Cordelta for coming on board as a corporate sponsor and The Mandarin as media sponsor.
The goal of this event is threefold and would involve a diverse crowd that broadly reflects the communities and sectors of Australia:
  1. To reflect on 10 years since the Gov 2.0 Taskforce Report, progress made or not.
  2. To identify and articulate the barriers to progress, and consider the old, new and emerging opportunities and threats.
  3. To (re}energise and activate a diverse community around the goal of better public sectors for a better society, both through reconnecting in this event, and through creating and committing to actions over the coming year.
The event will be in Canberra, where the Taskforce was launched, but people are welcome to create satellite events to connect local communities using the live stream and online tools to contribute to the day.
Please note this event is being run by volunteers, and any feedback, volunteering or support is welcome.
We hope this event helps contribute some momentum to a range of community and cross sector activities. We believe this needs to happen if we are to get the public sector we need. One that is collaborative, resilient, trustworthy, fair and which provides a stable foundation upon which all people can thrive.
Please also book a place in the kids creche if you need it, noting that teenagers are welcome in the event on a normal ticket.
We also have an anonymous survey running to get pre-event feedback to help inform the day, so if you can spare about 10-15 mins, please get a cuppa and participate in the Gov 2.0 Taskforce Recommendations Report Card survey.
The rough agenda is:
  • 09.30 - Welcome to Country
  • 09:40 - Introductions and outline for the day
  • 09:45 - Nicholas Gruen reflects on the original intent and hopes/fears of the Taskforce and observations from the last decade.
  • 10:00 - What was implemented at the time?
  • 10:05 - Government 2.0 as an enabler of citizen led initiatives
  • 10:15 - Gov 2.0 Taskforce Report Card - survey result overview 
  • 10:30 - Report card group session: To reflect on the survey results of progress made on Report recommendations, where we went backwards and what we wouldn’t do. Fully participatory session for attendees to discuss, review and identify what success might look like today..
  •  11:00 - Break - BarCamp signups
  • 11.20 - Primer talks for barcamp session (10 mins each):
  • Gov innovation trends: Alex Roberts reflects on global trends in public sector innovation and his observations of progress in Australia since the Gov 2.0 Taskforce (including with Design Gov).
  • Emerging tech and government - what technology trends have or could have the greatest impact for public sectors from the last 10 years?
  • 11:40 - BarCamp session: short self-nominated sessions for participants to present ideas about the barriers to progress, new threats and opportunities facing us, and to draw out the hopes and fears for the future.
  • 13:00 - Lunch
  • 14:00 - Action stations: After participants vote for the topics/themes they want to action, they each go to the “action station” of greatest interest around topics or themes to identify and commit to practical actions and experimentation over the coming year to improve public sectors, to further realise the original intent from the Gov 2.0 Taskforce, and to bring about a better future for all. Teams report their actions into the online tool.
  • 15:30 - Reflections from the day and report from action stations.
  • 16:00 - Close"

Greetings from Rottnest Island, just off the coast of Western Australia, near Perth, where I am with a couple of dozen lawyers, discussing how to digitize the law.

Autonomous Kei Car Highway
Nissan Dayz kei car
On Friday I attended the Spatial Futures Forum  on Intelligent Cities and Transport hosted by University of Sydney. One topic was autonomous vehicles. It was pointed out that these would not help those who do not own a car, and are outside the cities which have autonomous public transport. However, it it occurred to me that a form of miniature autonomous public/private transport system could be built for the zone just outside cities.

Nissan has announced its Dayz Wider Kei car will be equipped with semi-autonomous assistance with acceleration, steering and braking on the highway.

If such Kei Cars are used, then the width of a standard Australian traffic lane (3.5 m) could carry two lanes of oncoming traffic. Conventional vehicles, such as fire appliances, could use this road, with the oncoming traffic diverted to a passing loop (as is done with railways).

This would greatly reduce the cost of building a highway, as it would only need to be 3.5 m wide for most of its length. Where cost and space are at a premium, and conventional vehicle access is not needed, an even narrower single lane roadway could be used. This would allow bridges and elevated roadways to be quickly built from shipping container sized modules. Tunnels would only need to be about 3 m in diameter.

Design of computerized system contributed to the death of ten USN sailors

On 21 August 2017 the US Navy destroyer John S McCain collided with a civilian tanker near Singapore, resulting in the deaths of ten US sailors, and $100M in damage. The US National Transportation Safety Board report found the probable cause of the collision was "... a lack of effective operational oversight of the destroyer by the US Navy ...". However, also contributing to the accident was the computerized steering system: "Also contributing to the accident was the operation of the steering system in backup manual mode, which allowed for an unintentional, unilateral transfer of steering control.". This would be a useful report for students of safety critical systems to study.

John S McCain Bridge Control Station.
Drawing from IBNS technical manual;
color added by NTSB. Figure 4 of
NTSB/MAR-19/01 PB2019-100970.
The destroyer was equipped with bridge control stations with flat-panel touch screens, and a graphical user interface (GUI), in additional to a conventional steering wheel. The stations had an "emergency override to manual" function activated by what the crew referred to as the "big red button". This was intended to provide manual control in the event of a computer malfunction, and the designers no doubt thought it was foolproof: press the red button and steer the ship with the wheel.

However, as the NTSB detailed, the crew unintentionally
transferred control of steering from one station to another, but interpreted this as a failure of steering. This confusion may have been because the crew were uncomfortable with the automated mode of the system, and preferred to use the backup manual mode. However the backup mode was not intended for normal use, and allowed the control to be transferred without the operator noticing.

The  NTSB recommended crew being instructed to only operate the system in manual mode during an emergency. However, the underlying problem appears to be that the crew did not trust the automated system. This would require training the crew so they felt they could rely on the system, or to redesign the system to provide more intuitive feedback. Part of the intuitive feedback, I suggest, could be via manual controls.

The Bridge Control Stations have a ship's wheel, but this is an input only device, and there are no physical engine throttles, just a GUI display. One way aircraft cockpit interfaces display the operation of the autopilot is by physically moving the throttle levers. Similarly, in aircraft with a control yoke  the control moves in response to auto-pilot commands, and also provides tactile and visual feedback of the control responses put in by the co-pilot. The autopilot can be overridden simply by moving the yoke. If implemented on the ships bridge control, this would provide intuitive feedback as to who is in control, and an intuitive way to take control. The operator would be able to see, and feel, inputs through the wheel and throttles. If they wanted to override the automated system, or another operator, they just need to move the controls.

Some modern aircraft lack the visual and tactile feedback in controls, particularly those using side-stick controllers, rather than a yoke. However, in aircraft pilots receive intensive training in the use of these systems, and are sitting close to each other in the cockpit, so are usually able to see and hear what each other are doing. Even so, conflicting inputs have lead to aircraft accidents.  On a ship the operators are much further apart, which makes coordination much more difficult.

Walgett, Brewarrina, Bourke, Wilcannia and Menindee Lakes

Yaama Ngunna Baaka Corroboree
Tour 2019, Wilcannia.

I attended the Yaama Ngunna Baaka Corroboree Festival, from 28 September to 2 October, in western NSW. This was by bus from Sydney to Walgett, Brewarrina, Bourke, Wilcannia and Menindee Lakes, then train from Dubbo to Sydney. Mat Ward produced a detailed blog of the trip, there is the Water for the Rivers Facebook Page,
so I will just provide a few reflections of my own.

Sometimes you see a photo, and think: that is not real: it was staged: they added the smoke and colored lights.  Well
Mark Merritt's photo of the Corroboree at Wilcannia looks too magical to be real, but I am one of those dots around the circle: that is what it looked like. Leaving early, crossing the old lift bridge over the river to the campsite, I looked back and the moon had risen directly over the ring, the smoke hung low.

While I have written about the problems of telecommunications, and e-learning in regional Australia, this was an academic exercise conducted at a distance. There were two buses, two trucks for supplies, and a convoy of cars. It is rare for me to travel long distances with a large party, and at times voices were raised. But mostly it all worked out.

One highlight were the Brewarrina Fish Traps (Baiame’s Ngunnhu), with a tour by staff from the Brewarrina Aboriginal Cultural Museum. The fist traps may be the oldest existing human made structure.

Grapes of Wrath in the Pacific

On Friday I attended a performance of The Grapes of Wrath at the New Theatre, Sydney. This play is adapted by Frank Galati from John Steinbeck’s novel. As someone in the row behind me kept loudly telling their companion: this play is relentlessly depressing. 

This is a relatively straightforward adaption of the book, about  tenant farmers driven from the US Midwest by drought and economic depression. The promised land of California, proved not to be paradise with labor contractors conspiring with authorities to exploit itinerant workers.

While well directed, acted and with imaginative set design, I wondered how relevant this story of exploitation in the USA was to Australia today.  Then I recalled an Australian politician saying that pacific islanders should not complain about being driven from their land by rising sea levels, as they could always get work picking fruit in Australia.

Greetings from the National Gallery of Australia, where I am taking part in "Australia 360", a conference on regional security hosted by the Australian National University. The morning had conventional panels of security experts. The afternoon started with Professor Hugh White's provocative views, in his new book "How to Defend Australia". To make it more interactive we are being polled on questions to do with China, Australia, and the region, with the results displayed on a large screen, and Associate Professor Nicholas Farrelly, as the MC, walking around the floor getting the views of delegates. Professor Rory Medcalf quipped the MC could host a game show called "Geopolitical Survivor". My contribution was to suggest a 360 view should also include the role of India.
"Panel 3: How to defend Australia

This session is an interactive, hands-on component delving into the hard choices Australia has to make about its defence as the world rapidly changes.

Memoir from Programmer of the Apollo 11 Lunar Module

The book "Sunburst and Luminary: An Apollo Memoir" by
Don Eyles relates his experience programming the computer on the Apollo Lunar Module. This is a relatively modest first person recounting of someone who fell into computer programming, and ended up on the Apollo program as their first assignment. It would be useful for students who have ambitions of a career in computing to read.
"In 1966 the author, newly graduated from college, went to work for the MIT laboratory where the Apollo guidance system was designed. His assignment was to program the complex lunar landing phase in the Lunar Module's onboard computer. As Apollo 11 approaches, the author flies lunar landings in simulators and meets the astronauts who will fly the LM for real. He explains the computer alarms that almost prevented Neil Armstrong from landing and describes a narrow escape from another dangerous problem. On Apollo 14 he devises a workaround when a faulty pushbutton threatens Alan Shepard's mission, earning a NASA award, a story in Rolling Stone, and a few lines in the history books.  This memoir is a new kind of book about Apollo. It tells a story never told before by an insider the development of the onboard software for the Apollo spacecraft. It makes a vertical connection between technical details and historic events, but by broadening the story using his own experiences as he grows into adulthood in the 1960s the author draws a parallel between that era of successful space exploration, and the exploration, inner and outer, that was taking place in the culture."

ps: I read the copy in Libraries ACT.

Australia Post Digital Identity Service Rescued by Chinese Shoppers After Failure 20 Years Ago?

Australia Post Digital Identity
announcement from 1998
Stuart Robert, Minister for Government Services, announced 24 July 2019 that Australia Post’s Digital iD service had been accredited as a trusted identity service provider under the Trusted Digital Identity Framework (TDIF). What the Minister did not mention, was Australia Post's previous digital identity service failed 20 years ago. But Daigou might provide the use case for the new service.

In 1998 I applied for an Australia Post "KeyPOST" digital certificate, at a cost of $20. Here is the text from the Australia Post web page of the time:
"Australia Post plays a role in introducing security and trust into transactions performed over the internet. It does this by providing the public (individuals and organisations) with a convenient access point to acquire a digital certificates. KeyPOST is an identity check performed on behalf Certification Authorities.
Digital certificates are now available via the KeyPOST Registration Service, from SecureNet Certificates (SNC). Information and application details for Certification Services provided by SNC are available on the SecureNet Certificates website:"
From "KeyPost",  Australia Post, in the Internet Archive, 20 May 2000
There were a few glitches with the process, but eventually the certificate was issued. However, Australia Post ceased the service the following year. There appeared to have been very few certificates issued and the manual processing required to issue them was unlikely to have covered the cost.
"Australia Post has decided to cease its KeyPOST(tm) operations concerning the generation of private keys and certificates from 1 August 1999. Unfortunately, the service has not met expectations and its growth and take up rate have been less than what we expected.  I would like to thank you for your support and interest in the service, but >it has become increasingly clear that the service is not commercially  viable."

Chinese Daigou Use Case

The daigou channel, by Bang Xiao  &
Sean Mantesso, ABC News, 31 Jul 2019

Hopefully, those at Australia Post planning the new digital identity service have learned from the previous failed service. A use case which might make the new service a success is the multi-billion dollar personal shopper business. Chinese consumers contract 150,000 personal shoppers in Australia (daigou), who are mostly Chinese students, to buy products for them. The Australia Post Digital iD could be used to authenticate the personal shoppers, perhaps in combination with a blockchain. The consumers could be assured who is doing the buying, and they were getting the correct product. The governments could be assured all taxes and duty were being paid.
