Climate mitigation and adaptation in the ACT

Greetings from the Canberra Renewables Innovation Hub, where the ACT Government is holding a workshop on the Climate mitigation and adaptation in the ACT: costs, benefits and implications report (22 February 2018). It is going to be a difficult exercise, as this is a sixty eight page technical economic report, presented to a general audience.

ps: It turned out to go well, but this wasn't really a general audience, but a self selected group of experts and enthusiasts.  

My suggestions were:
  1. Public-private pocket parks: These would be modeled on the private part at the center of the City-edge development at O'Connor. This looks like a public park but is owned by the bodies corporate of the surrounding apartments. 
  2. Pop-up Community Groups: ACT Government would provide a website where a group of residents could register a community group. When enough people had joined, this would be a legally constituted group and receive government support to run a community garden and the like.

Federal Regulation Needed to Stop Financial Institutions Placing Customers at Risk of Scammers

Had a call from someone claiming to be from NIB Health Insurance. They wanted to discuss my policy and asked me for personal details to verify who I was. However, when I asked the caller to verify who they were, they could not. They provided a telephone number and suggested I call. I explained that as they gave me the number, I could not use it for verification. They then gave me a web address to check the number, but again, as they gave me that I could not rely on it being genuine.

The caller did not seem to grasp the fact that because I get so many scam calls, I have to assume anyone calling is a scammer, until they can prove otherwise. Assuming this caller really was from NIB, the company appears to not understand that they should not call customers in this way. By doing so they make it easier for scammers. I suggest a mandatory code of conduct needs to be put in place for insurance companies, and other financial institutions, to stop this practice.

4th Age of War with 3D Printed Pizza Drone Delivered to Battlefield

Greetings from the Australian National University in Canberra, where Dr Albert Palazzo, Director of War Studies at the Australian Army Research Centre is speaking on "Transition Point: Embracing the 4th Age of War". He started with 3D printing (additive manufacturing), which is already being used to produce replacement parts on-board US warships at sea. A more amusing example was the US Army experimenting with 3D printed pizza drone delivered to the battlefield.

Dr Palazzo then drew a contrast between a traditional trade route map of the world and a data transmission map. Current main routes are trans-Atlantic and he suggests this is where wealth will be created.

Dr Palazzo suggested that we don't know who makes the rules about trans-national data communications. This clearly is not true. There was a well established international governance framework for telecommunications before the Internet. This was supplemented with new bodies and rules with the advent of the Internet. I helped establish this structure and stumbled into one of the meetings of the people who ran the Internet one day in Stockholm.

Dr Palazzo then claimed that AI can't come up with quirky original actions and may result in predictability on the battlefield. My experience is that AI comes up with anticipated results, as it is not possible for the human, even the one who programmed it, to anticipate how the data will interact.

One area not addressed by Dr Palazzo were information warfare and irregular warfare techniques enhanced by the Internet. Examples of this are the use of sophisticated social media by terrorists, high quality videos by the Russian military in Syria and "Little green men" deployed in the Ukraine. Western military forces have had difficulty in countering these due in part to a lack of suitable training and doctrine.

That these new forms of warfare are now here was brought home to me when ANU started offering a course in "Offensive Cyber Security Operations" (COMP3702).

One point I agreed with Dr Palazzo on was that the barriers to entry with some new technologies is low. This just needs engineers.

ps: My nephew, Sam Worthington, is an engineer and just set up Rapid 3d Printing.

ACT Virtual Big Battery Proposed

Greetings from the Renewables Innovation Hub, in Canberra, where I have been attended a workshop on the Energy Efficiency Improvement Scheme (EEIS). This is a suite of measures to reduce energy and greenhouse gas emissions. One proposal is to provide incentives for  Demand Response (DRM) capable air-conditioners. Some participants pointed out that while there were many DRM capable units already installed, few were activated. So I suggested the ACT implement a DRM controller and require all units under the scheme to be connected to it, unless they were connected to an alternative DRM controller. This would provide the ACT with a virtual (and much cheaper) alternative to South Australia's big battery.

Upgrade Your Computer with Stuff from the Tip

I was amused to read in John Davidson's "Three gadgets to give your computer the facelift you so richly deserve" (AFR, 18 February), that I could upgrade my computer with a new keyboard and mouse for less than $450. My computer only cost $298, so it would seem a false economy to upgrade it with peripherals costing 50% more than the computer. I did upgrade my computer with a wide-screen LCD desktop display. This cost nothing at all, as I found it on the roadside on rubbish collection day. For those not willing to try a road-side upgrade, I recommend the tip-shop or charity. There are peripherals in abundance for a few dollars. If you want to refresh a very old computer, then an upgrade to Linux will breath new life into it. I am reluctant to but a second hand laptop, but even a new one is not going to cost around $500.

Love Letter to the Libraries of Canberra

I walked into the UNSW Canberra Library at the Australian Defence Force Academy (ADFA), as I have done every few weeks for many years. But this is the first time someone has rushed up, handed me two heart-shaped chocolates and asked me to write them a love letter. Well, not to them, but to the library. So here it is, to Canberra's academic libraries.

Libraries Like Airport Business Lounges

This love of libraries was not one which started early. At school, the library was more of a chore, than a pleasure (except for the forbidden books locked away). The local public library was too far away and intimidating to enter (looking like a courthouse). Recently I visited where I grew up, and there is a new "Wynnum Library", very welcoming and accessible. I spent an hour browsing and recharging my laptop. It was controversial, being built on top of a supermarket, but I like it, because it looked like an airport business lounge, not a courthouse.

My love of libraries came later in life, first as somewhere to sleep at university, before the next party. Then much, much, later, somewhere to find knowledge.

One of the wonders of Canberra's (and most of Australia's) public and academic libraries is that they are open for anyone to walk in. In some countries, you have to show your ID to enter a public library and the public is not admitted to university libraries at all.

NLA and the Internet Revolution

Canberra's libraries give generously of their facilities. This does not involve just keeping copies of other people's books. Along with having an excellent cafe and bookstore, the National Library of Australia (NLA) had a central role in getting the Australian Government on the web. In the 1990s a cabal of politicians, public servants, academics and industry people were working on making government information freely available online. At the time this was contrary to government policy: the government sold information, on paper, in its bookstores. It was decided each government agency would create a website. But there would need to be a central index and none of the central agencies wanted to do it. So the National Library of Australia stepped in and created the Australian Government's first home page. This was so successful that government policy was changed.

ANU and the Innovation Revolution

In my closing address for the 1998 Information Industry Outlook Conference in Canberra, I argued that Australia could emulate Cambridge (England) as a high technology industry center. I could put this confidently, not only because I had been and talked to the people doing it in Cambridge, but because I had read a book. Not really read the book, so much as devoured it. In the ANU's Hancock Library I found Segal Quince & Partners 1985 report on "The Cambridge phenomenon: the growth of high technology industry in a university town" (still in the ANU library). Over several days I made notes, appropriately, on a Cambridge Computer Z88. I included that Summary in a book, which is mentioned occasionally by Cambridge scholars (who apparently had difficulty finding a copy of their report). Technology companies are now springing up in Canberra, next to the ANU campus.

UNSW Canberra and the Education Revolution

Two decades later, I became almost by accident a mature age graduate university student. My studies were in online education and mostly conducted online, at institutions 1,000 km and 13,000 km away. But I found e-books not ideal for intensive study and was delighted to discover that all of Canberra's university libraries would let me borrow books. Most useful for education studies were the small and friendly Australian Catholic University library and UNSW Canberra. UNSW Canberra had a collection of books published decades ago by Open University UK (OUUK) on how to design, plan, budget and deliver distance education. These books had been overlooked in a rush to MOOCs as a new form of education, but many of the problems and solutions discovered with MOOCs has already been addressed decades ago by OUUK.

I left the Department of Defence in 1999, but DoD have now followed me to the ANU (paying for an extra floor in the new ANU Computer Science building). So its back to UNSW Library to brush up on cybersecurity.

Global Financial Crisis Risk from Renewable Power Technology

Greetings from the ANU Climate Update 2018 at the Australian National University in Canberra. Professor John Hewson from the ANU Crawford School of Public Policy warned that advances in renewable power technology could precipitate a global financial crisis. The concern, as I understand it, was that wind turbines, photovoltaic panels and batteries are dropping in cost. The problem then existing fossil fuel investments could become suddenly financial nonviable, disrupting financial markets.

I was reminded about sudden changes in technology yesterday, with the successful launch of the SpaceX Falcon Heavy reusable launch vehicle. This has been under development for at least ten years, but the success makes it a viable option for launching satellites at about one third the current cost.

It is similarly easy to overlook incremental improvements in renewable energy technology, until it is packaged in an understandable form. An example South Australia's 100MW battery and batteries for 50,000 homes.

ANU Climate Update 2018

Greetings from the ANU Climate Update 2018 at the Australian National University in Canberra. The opening address was by Shane Rattenbury, MLA, Minister for Climate Change and Sustainability, ACT Legislative Assembly. He invited community comment on the ACT Climate Strategy to a Net Zero Emissions Territory.

The Minister surprisingly admitted that the Australian Capital Territory (where Canberra is) was easily able to become carbon neutral. This could be done as the ACT doesn't have a lot of coal fired power stations to replace.

ps: I am just finishing updating the notes for my course "ICT Sustainability" being offered by ANU in First Semester, starting online 19 February.

U.S. Tsunami Warning System Problem

Tsunami Warning after an earthquake
near Alaska at 01-23-2018 09:35:57 UTC
The U.S. Tsunami Warning System issued a warning after an earthquake near Alaska at 01-23-2018 09:35:57 UTC.

However, when I checked the home page at 11:15 UTC the map did not show the earthquake location and instead said "Earthquake Layer failed to load" and "Alerts/Threats Layer failed to load". This would appear to be because the system was overloaded. I then canceled the page request, not wishing to make the situation worse.

The NWS Tsunami Alerts Twitter feed was working at the time. However, the twitter alerts contained a link to the same non-functioning web page:
    NWS Tsunami Alerts

    TSUNAMI WARNING 4: See  for alert areas.
    M7.9 175mi SE Kodiak City, Alaska 0032AKST Jan 23:
There were some maps provided direct in the twitter feed, which did display:

    1m1 minute ago

    Tue Jan 23 11:18:49 UTC 2018  event picture
However, these maps are difficult to interpret, as they showed a series of predicted arrival times as colored lines, with no scale as to the size of the wave. The waves were shown reaching Australia in 11 hours, although no warning had been issued by the Joint Australian Tsunami Warning Centre. 

Colored dots on the map indicated the location of tidal gauges and "DART". Not explained on the map, DART is a system of "Deep-ocean Assessment and Reporting of Tsunamis" detectors. 

Fortunately in this case the tsunami was only 6 inches high (as reported at Old Harbor Alaska 0256  PST Jan 23). However, I suggest revising the design to use simple static map images on the web site, using a few colors, so the file is small. Also the use of extensive JavaScript should be avoided to allow the page to load quickly. At present the HTML file is only 61 kBytes, but the other files are 3.4 Mbytes, including a 1.2 Mbyte JavaScript file.

The tidal gauge and DART locations are not of use to someone who wants to know when, when and how large a tsunami to expect. These should be omitted from the map, unless they show a reading. The predicted arrival time should be limited to a few hours, until the existence of a significantly sized tsunami is confirmed.

Fix for Blank Screen at Grub/Linux Login: VGA Dummy Plug

VGA Dummy PlugMy a Leader Companion 220 has been running well since 2014 with Linux Mint. However, it has developed the annoying habit of displaying a black screen when booting, unless a VGA (or HDMI) external monitor is plugged in. The LCD screen then works fine (even when the computer is suspended and resumed without the external monitor), but a cold boot with an external monitor gives a blank screen.

I found hundreds of queries on the web about this problem, with any conclusive software fix. What solved the problem was a "VGA Dummy Plug". When inserted in the computer's VGA socket this tricks the system into thinking a monitor is installed and allows the boot.

Apparently such plugs were used in some bitcoin mining computers. A PC chassis was used with multiple graphics cards. But to for Microsoft Windows to recognize the graphics card , each required either a monitor plugged in, or a dummy. Thus there are many VGA Dummy Plugs offered on

However, I made my own using the instructions provided by . I used 86 Ohm resistors soldered to a DB15HD plug (as used for VGA) for about AU$5.
