2020 election campaign

Today (Sunday) National had its (virtual) campaign launch. This, the day after the election was due to take place. It also took place in the wake of an embarrassing error in its economic plan announced yesterday. They also have a completely different leadership than what was in place when the original election date was announced. To be fair to National this year has not been kind to anyone in NZ, but they seem to have been hit particularly hard.

New Zealand National Party

It is in exceptional circumstances that people can get caught out. David Clark would probably have expected to still be Minister of Health and would have looked forward to implementing the recommendations of the Health and Disability System Review. In all probability he would have been remembered as a very good minister. However, he was not equipped for the circumstances of the pandemic, and had to resign to be replaced by a better communicator. So Labour has also changed in response to the crisis.

The news media also got found out somewhat. They expected to cover the different points of view, and hold the authorities to account. What the majority of people wanted though was them to be a channel for sharing information. People didn’t want to be confused by questions, and muddying the water. Up until this year covering politics had become a game, and politicians were praised for clever politics, whether it was good for the country or not. It changed this year as people no longer wanted politics, they wanted to be part of a team.

The referenda (End of life choice & Cannabis) were set to be a big part of the election. For some people they were more important than who would form the government. Both questions are complicated and there are good arguments for and against, but there would be a danger of misinformation dominating the debates. This has got lost in all the conspiracy theories about the virus, 5G, Qanon etc. Even parties like Advance NZ and the New Conservatives who can be expected to be concerned with euthanasia, are getting involved in lockdown protests.

New Zealand Protesters Rally Against Lockdown - The New York Times

When the election date (yesterday) was announced in January the virus had not yet been given its name, and was something that affected people elsewhere. We had just started to see an effect on tourist numbers, but it looked like the election would be about economics and competence. The government was vulnerable due its failure to build as many affordable (kiwi build) houses as it had promised. On the other hand the National party leader (Simon Bridges) had failed to build any popularity.

By February it was clear that the virus effects were going to be more significant, and the government restricted inbound travel and started offering support to affected businesses. So covid-19 and the government response became the focus for politics. The general concern for health and approval of the lockdown process has carried over to popularity for the government. Ardern’s open style, her passion for kindness and her calm demeanour have helped to align people for the health response, and also to attract voters to the party.

Polls gave the government an unheard of lead. Where the election was looking close in January, by May it was looking anything but. The smaller parties were struggling for oxygen and everybody was rushing to find something different to make them stand out.

An election like no other: with 100 days to go, can Jacinda Ardern maintain  her extraordinary popularity?

National found it hard to find the right message. When they had seemed hard on the government they had been punished. In the end (after 2 changes of leadership) they have settled on that they would do the same only better. New Zealand First have distanced themselves from the government saying that they disagreed with many decisions, and have been a handbrake on (what they deem to be ) bad decisions. The Greens have tried to pitch themselves as more progressive than Labour (without actually saying that Labour have been ineffective). The only smaller party that is looking to have gained is ACT which can openly criticise the government without actually offering anything.

With the second outbreak in August, and alert level 2/3 controls, campaigning became difficult. Delaying the election seemed prudent. The government might have had to pass legislation to help the health response, and needed parliament to be sitting a bit longer. So we still have 4 weeks to go. Many people will be voting based on the government’s response so far, but the next government will be in charge for 3 years. There is still more to come from the virus, and we can’t go back to normal, but increasingly the focus needs to be on what comes next.

Both major parties seem to be too keen to get things back to what they were before. The opportunity for real change seems to be missing. What do we really want NZ to look like in the future. When travel is freed up, do we really need to do so much of it? We know it is unsustainable. We have low productivity in NZ because a large portion of our economy is devoted to tourism and hospitality, which are bedevilled by low pay. We need a lot of seasonal workers from overseas to help with agricultural workloads. Nobody is talking about solving these problems and making the future better.

So if you come across politicians out campaigning, make sure you ask them the hard questions. If they say they can do things better ask them to prove it. Ask them to show why their vision of the future for NZ is the right one.

Your vote is valuable. Make them earn it.

the PARTY party – Preparing to Speak Professionally

a longer toastmasters speech: 18 – 22 minutes.

delivered on 17 September 2020

No I am not going to speak professionally. That would take a lot of promotion and time. It would be good for my ego, but that is not how I see myself. But this was a fun speech. I pretended to be a party leader, firing up the membership to go out and get us votes for the election.

The speech had 5 parts with times as planned

  1. 3 minutes: Welcome and thanks. Who are we? what is our schedule? I got some members to stand up and take bows for their work: Duncan for putting up the billboards, and Cassie for making the TV ad.
  2. 5 minutes: policy platform number 1. The Great Leap Backwards. This is borrowed from the McGillcuddy Serious Party. The idea is that the peak of civilisation was reached at the beginning of the 19th century at the time when European settlers arrived in NZ. It has been all downhill (a blind alley of progress) ever since. We should go back to a simpler time without burning fossil fuels and forcing people to slave over a computer all day. More people will work on the land and craftsmen will support them by making tools and bread etc. Entertainment can be provided by minstrels and story-tellers, and people can rediscover community.
  3. 5 minutes: policy platform number 2. Happyness. It would be everyone’s right to be happy. In fact everyone would be obliged to be happy. We wouldn’t copy the Americans and enshrine the pursuit of happiness in the constitution, which doesn’t seem to lead to much happiness itself. We would change the Bill of Rights to add the right to be happy, and any laws that make people unhappy would have to be changed. We would make it a crime to not be happy, but instead of punishing unhappiness people would get treatment. This would have the effect of emptying our prisons and stopping the use of psychoactive drugs as crime and dependency stem from unhappiness.
  4. 5 minutes: policy platform number 3. Abolish money. The use of money encourages the accumulation of wealth, which causes the vast mal-distribution of resources that causes deprivation and misery. Without money people will only produce what they need and what they can trade with their neighbours. Where wider trade is necessary we would go back to using pounamu (greenstone). This has the advantage that it would be very hard to hoard and can be made into jewelry even if it is not needed for tools.
  5. 3 minutes: summary. What do we still have to do before the election? How do we go out and sell the party and the platform? Why is it our time? How we are going to double our support every day?

How did it go?

I lost my train of thought a couple of times, and missed out on some material, so the times ended up being a little short (17:55). In general it went well. Nobody fell asleep. Some found it amusing. There was some audience engagement. Maybe I should have asked the audience some questions, or got them to repeat the slogans.

Rana did the evaluation. he was quite complementary. He recommended I use a cheat sheet so that I don’t forget what I was going to say. Useful, but if I prepare properly I shouldn’t forget. His challenge was to use more time, as this is the point of the project.

The timekeeper (Mitch) also commented that I could have added a little more detail to eke out a little more time from the speech.

So I learned a lot from the exercise. I would have to do more work if I was to speak professionally, but can have confidence to give longer speeches. I look forward to hearing other members attempting the project.

Information, Misinformation and Theatre

We all know where to get the best information about the pandemic: from the government, Ministry of Health, and the World Health Organisation. But what about when that seems to contradict our own experience, or when our friends on Facebook are telling us something else, or when we simply don’t like what we are hearing?


Throughout the course of the pandemic the (almost) daily 1 o’clock briefings with the prime minister (PM) and director general of health (DG) have been compelling viewing. When we were stuck at home they provided us with an update in case numbers, a view of how successful we were as a country, and simple instructions for behaving and coping with the extraordinary situation. On the days when Jacinda Ardern or Ashley Bloomfield were unavailable, or when no briefing was given, we felt like we were missing something. The message was calming, but also stressing the importance of us all playing our part. We all felt part of “the team of 5 million”. They gave NZ (and the world) the concept of a “bubble” of people we could freely associate with without risking aggravating the outbreak.

The briefings have been incredibly open and honest. After the news and message, the reporters have been able to ask questions. The opposition was also given a forum for questioning ministers, officials, business people and anyone else affected by the fight against the virus. They held the government to account, and questioned the veracity of some of the statements. To most people listening it seems that the PM and DG were being badgered, and disrespected. Some of the reporters received abusive messages. The opposition had to change leader. people really wanted to believe what we were being told.

Covid-19 live updates, April 19: Nine new cases in NZ, level four exit  criteria outlined | The Spinoff
The daily briefings were unmissable and were very important for compliance

So why do we have large lockdown protests? Why did someone ignore the requirement to self-isolate, sparking the latest sub-sub-cluster and probably extending restrictions another week or more?

Cognitive Dissonance

One concern is when what people are hearing doesn’t match their personal experience.

During level 4 Bloomfield would often say that there was plenty of masks, testing supplies and flu vaccines in NZ even though they were in short supply all over the world. However GPs and aged care workers were finding it difficult to get enough. It wasn’t like New York, where intensive care nurses were using rubbish bags, and re-using masks, but it also wasn’t good enough. The poblem arises because the Ministry of Health is not a doing organisation, it is a policy organisation. GPs get their supplies from the DHBs. One DHB found that their stock of masks was unusable, another had different policies for who should get masks. People didn’t hear the reasons, or even how complicated it is, they just heard that the information they were given is not completely honest.

Official recommendations have changed over the course of the pandemic. This does not mean that the MoH & WHO are incompetent. It is they are working with very incomplete information, and as time goes on the science becomes clearer. Initially they were not recommending general use of masks, because it was not clear whether there was a net benefit (and masks were needed for medical workers). It was thought that transmission was mostly by contact. After a while the evidence came in that the virus was transmitted through the air and so mask use could be helpful. Some people felt that the changed advice made the MoH look incompetent.

NZ COVID Tracer app
The covid tracer app was not given sufficient importance initially, which mean that usage was low in level 1

Most people didn’t know any body who had the virus. This is a reflection on how successful we were in eliminating it, but it meant that people didn’t experience its seriousness. On the other hand people did experience the difficulties associated with the counter-virus measures. Some people lost their jobs. Some couldn’t get medical or dental treatment. Concerts were cancelled. Restaurant meals were unavailable. Over time the balance became hard to appreciate.


Politicians from non-government parties (even NZ First) wanted to disparage the government response. News media wanted to increase their readership and show their independence. That meant that stories where things didn’t go perfectly became highlighted.

There were an endless series of stories from people complaining about conditions in Managed Isolation facilities. Some stories would say that things were too severe, some not strict enough. National party MPs leaked stories to the media, even to the point of releasing a list of names & addresses.

In general, scientific opinion was very strongly in favour of NZ’s response, but there will always be contrarian scientists. A group of academics and business people started a campaign (plan B) pushing for a different response where we allow people to get infected, but protect the elderly and vulnerable. It is based on very questionable science and dodgy statistics, but got a lot of airtime every so often.

To some these had an effect. Any loss of confidence in the competence of the government response had the effect of reducing compliance.

Conspiracy Theories

There are people in NZ who do not trust the government (any government). Some with good reason. Campaigns against things such as child uplifts by Oranga Tamariki, unjust convictions, over aggressive policing, 5G, 1080 poison, vaccination, etc have significant and vocal (if small in number) support. This is not to mention the anti-immigrant, anti-muslim “great replacement” groups.

Material about these are often broadcast on social media. If people see an article shared by someone they know and trust, then they are more inclined to take it seriously. Some people no longer believe anything they see on TV news, or read in the newspaper, because it is at variance from the information that they are reading on Facebook. People who get paid for clicks are incentivised to create material that gets shared like that, so it gets more and more outrageous.

5G and COVID-19: the luddites are back!
In the early days of the pandemic a link was made between the centres with outbreaks and 5G networks. There was a worldwide spate of attacks on cellphone towers.

Then the focus shifted to the origin of the virus. Many slick videos pointed to an engineered virus. Some claimed it was China, some the US “deep state”. Others claimed it was a trick by Bill Gates to get us all vaccinated so that he could control us.

In NZ the practical upshot of this is that some of the people infected in the latest outbreak did not believe the official narrative. There was a reluctance to get tested and a reluctance to isolate properly. Because of this there have been more infections and it has taken longer to control the spread. Probably this will delay our return to level 1 throughout NZ.


There are a number of actions which are scientifically known to control the spread of the virus. Hand washing, masks on public transport, distancing, avoiding unventilated indoor spaces are all known to reduce the chances of getting infected. Testing, contact tracing and self-isolation are effective at controlling the spread. In combination these can reduce the reproductive rate below 1 so that an outbreak will die out.

There are some measures that are applied even though they seem to have little or no effect. These include temperature measurement, “deep cleaning” where an infected person has been, wearing masks outdoors. These (very public) measures are often a case of being seen to do something. It may be that they are necessary to reinforce the messages about the effective interventions.

If I wear a mask while walking down the street, I may not be changing the odds of my catching or spreading the virus, but I am helping to normalise mask wearing, and reminding people who see me that we still are in the middle of a pandemic. In our last period at level 1 we seemed to forget.

The year so far part 2 – Lockdown and freedom

By the end of March lockdown had become inevitable. There were multiple clusters of virus from Auckland to Bluff. Our health system was not in a state to cope with large numbers of patients. There were questions about supplies of PPE and reagents and laboratory space for testing. Our public health systems and contact tracing were woefully short of capability.

We knew what lockdown looked like from Wuhan and Northern Italy. The two experiences were quite different. They showed that people could survive and that essential supplies could be maintained. They differed in the degree of control of people’s movements. In Wuhan some residential buildings barricaded all doors leaving only one entry/exit and people had only short times they were allowed out for shopping.

The NZ lockdown was going to be a bit kinder. We were to be allowed out for unlimited local exercise. The definition of “local” was fluid, and some pushed the boundaries (including the Health Minister). Generally people understood the conditions and behaved well. The number of people walking and cycling in cities increased dramatically. DOC closed all tramping tracks, including cancelling my booking for a hut over Easter.

Wellington with few cars moving under level 4

It was quiet. Car traffic dropped away and the air was cleaner. Cycling was more pleasant. ACC claims dropped to 20% of normal and over Easter nobody died on the roads. Overall people were healthier and safer (and some even happier) while locked down.

The number of people with flu-like symptoms dropped away dramatically to almost zero during lockdown

We discovered who were essential workers. Cleaners and supermarket workers gained in status and some even got paid extra. They were the people that were out risking infection to make sure that the rest of us could survive. Many of us could work from home and were largely unaffected, but a number of people were unable to work. The government became very generous, giving subsidies to companies to pay workers when they had no revenue. There has been some abuse, but overall it has avoided some company collapses and large unemployment. The bill is still to be paid.

The number of daily cases dropped quickly soon after lockdown started.

Initially the lockdown was set for 4 weeks. Then the tail of some of the clusters kept producing cases and level 4 was extended for a bit. When level 3 started everyone held their breath to see if the number of cases would rise again. Luckily they continued to decline and we soon dropped down through the levels to 2.5, 2 and then 1 about 12 weeks after we had first gone to level 2 in March.

First longer ride to Remutaka Forest Park past Wainuiomata at level 3.

At level 1 we had freedom. The only restrictions were on international travel. Nobody can enter the country without quarantine (managed isolation) for 2 weeks. Professional rugby played in front of crowds in the tens of thousands. The NZSO gave a free concert at the Michael Fowler centre. We were the envy of the world. Toastmasters went back to in-person meetings. We had no active cases in NZ, being one of the largest countries in the world to say that.

But it was a nervous time too, and (perhaps inevitably) it didn’t last. In June we had 2 more cases. People had come from the UK and had been given leave to exit quarantine early to drive from Auckland to Lower Hutt to support their father after their mother died. After arriving at Lower Hutt they tested positive. Everyone was surprised that they were allowed out without testing. A new testing regime was instituted in quarantine. The testing picked up more cases which may have been partly because the countries where people were coming from were getting worse. Luckily the 2 cases didn’t seem to infect anyone else, so we could breathe again.

Complacency kicked in again, and the number of people presenting for testing dropped to very low levels. People didn’t use the app much. The health minister started trying to talk up testing. The evidence around the world was showing that wearing masks had real benefit, and could reduce the need for movement restrictions. Changing the message is always difficult, and the parliamentary opposition started intimating that there was something sinister behind it.

Then on August 11th the first community case was found again in Auckland. The family was tested and 4 were positive. Auckland went back to level 3 and the rest of the country to level 2. It turned out that the first case had left work sick 9 days earlier. It is not clear why they weren’t tested at the time, but complacency probably led to it. By the time they were detected they had infected 2 work places and several people on buses. Members of a church also got infected. Genomic analysis linked all the cases together even when there was no direct link found.

So now we are at level 2 (level 2.5 in Auckland). When will we get back to level 1? Do we have confidence in our health systems to cope with another outbreak? How do we get to where travel is more available? When do we get back to normal? What is “normal” anyway?

The year so far – part 1 – how did we get to lockdown?

I think I should have revived this blog at the beginning of the year or last year to have documented the course of the pandemic. It is an exceptional event (some say the most significant event worldwide since World Wide II). There are examples of personal diaries that incidentally documented world events. The diary of Samuel Pepys is interesting as it was written in London over the period of plague and fire as well as political change. The best example so far from this pandemic is Fang Fang’s diary from Wuhan (here in chinese – or available as a book in English).

Let me try to reconstruct it. It will exclude lot of personal stuff, but also miss some interesting things which look trivial in hindsight. It is hard to remember when the world ran out of masks, hand sanitiser and toilet paper.

2 December 2019: I decided to ride to work every day in Summer. I used my old (very old) road bike. It was slow (lots of people passed me), but I managed to get to work with all the showering gear and clothes I needed. As the days went on I got better at it but the limitations of my old bike became apparent. I broke a lot of spokes in my back wheel. I repaired it enough to get home.

24 December: Christmas eve – I left work early. In Petone I ran into the back of a car and broke a brake cable. I don’t know whether the cable broke causing me to hit the car, or broke after hitting the car. I bought a new cable and fixed it, but it really is time to get a new bike.

30 December: After coming back from holiday in Palmerston North. I ordered a new bike. of course I would not get it immediately due to holidays. Australian bush fires are starting to affect NZ. The air smells of smoke.

1 January 2020: I read a report that SARS was back in China. Someone (later named as Li Wenliang) posted a message on Wechat, and was admonished for spreading rumours. An outbreak of unexplained pneumonia was reported to WHO. Smoke from bush files more noticeable.

3 January: A lovely still day – I paddled down the river and across to Matiu/Soames Island. No camera to take a photo to prove it. Tension overseas as the US murder an Iranian leader in Iraq.

6 January: Back to work (on my son’s mountain bike). Not many people around town as a lot of people don’t start again until 13th. Lots of cafes and lunch places still closed. Generally I get my lunches from the New World supermarket.

8 January: My new bike arrived. I had to buy pedals and shoes, so it was not until the 10th that I could ride to work. It was much more enjoyable to ride, and I was much faster. I also ordered some more gear (lights, clothes bag etc) from Aliexpress in China.

16 January: Japan reported its first case of the virus. Suddenly it looks closer to my son, studying in Kobe.

20 January: the fish and chip shop across the road from work has a note saying that they have come back from China (Guangzhou), but will stay closed for another week as they didn’t want to risk spreading the virus – as cases had been reported in Guangzhou.

23 January: the world watched in amazement as China locked down Wuhan, and restricted travel elsewhere.

28 January: New Zealand banned travel from China (against the advice of WHO). WHO didn’t appreciate how poorly prepared NZ was for such a disease. My bike accessories are going to take longer to arrive from China.

3 February: Share prices down in NZ due to worries about tourism and education markets.

4 February: Mercy flight bringing 158 New Zealanders from Wuhan arrived. The passengers go to quarantine in Whangaparaoa for 2 weeks.

17 February: memorial for cyclist killed on SH2 a few weeks ago.

25 February: Big drop in share price all over the world as Chinese production dries up and recession looks inevitable.

28 February: first confirmed case of the virus in NZ in a woman who traveled from Iran.

2 March: Travelers from Northern Italy and South Korea are required to self-isolate for 2 week.

16 March: I bought a freezer to stock up on meat. Who knows what is going to happen, but NZ is not immune to what is happening overseas. Time to start hoarding flour, rice, canned food etc.

18 March: the government warns NZers overseas to come home while they still can.

21 March: The PM announces the 4 level alert system and says that NZ will immediately go to level 2.

23 March: With confirmed infections growing the PM announces that NZ will move to level 3 and that level 4 will start in 2 days time for 4 weeks. I go home early to get my home office set up.

24 March: I return to the office (by bike) to pick up some more possessions, and to reset my password in anticipation that it might be difficult from home. Lots of people were taking chairs desks, screens etc home so that they could set up. Nobody knew how long before we could return.

26 March: Working from home: At lunchtime I went out for a bike ride around the Hutt valley. There were almost no cars. It was quiet, and the smells had gone. I could enjoy lockdown I think.

Back to the blog

The toastmaster’s project “Write a compelling blog”.

The project requires me to write a minimum of 8 blog posts in a month. That means that I will be adding a post every 2-3 days to this blog during September. I will probably write about the things that occupy my thoughts:

  • toastmasters
  • cycling
  • work (technology)
  • politics
  • covid-19

I might also throw in something else just to confuse people.

So lots have happened since I last picked up my pen keyboard. In response to the pandemic, NZ has settled on a strategy of elimination and we experienced 5 weeks of stringent lockdown, followed by slowly freeing up until we had 2 months of almost normality. Now that we are in the second phase of a second wave it might be another 2 weeks of level 2 before we can breathe again.

So yesterday, I decided I needed to go back to the office and toastmasters. It was great to get back on the bike, and as a bonus the days have lengthened to the point that it was light at 7am when I left home. Traffic seemed as heavy as ever, and my legs seemed sluggish after days of inactivity.

My bike – I have acquired more lights since this photo was taken.
The sort of hazards I encounter cycling to work
A more scenic part of the commute

The office was mostly empty with only 3 others on my part of the floor. It was nice to visit a cafe for lunch and have some real conversations. Work meetings were online and I could have done everything from home just as easily. This is our new normal – we are allowed to go to the office but no more than half of us can be there at once. No more than 2 people in a lift at a time, and the stairs are marked, one set for up and the other for down. Most people are happy to stay at home.

Toastmasters at level 2 is much the same without the handshakes. We space the chairs out and probably our capacity is not much more than 10.

More people are scanning the QR codes, but still not enough. The only way we can avoid lockdowns is to know quickly who we are in contact with so tracing is quick. We will continue to get outbreaks. People and goods are coming and going and although we make the odds of infection form each interaction low, over time it adds up. NZ’s situation of many weeks of level 1 freedom interspersed with 2-4 weeks of restrictions when some gets through, is probably the best we can get. It would be nice to think we can share travel bubbles with the islands (without putting them at risk) or other countries (without putting us at risk), but that seems far off.

I wrote a speech (below) 3 years ago about voting and the election. I pondered how the chosen government would react to a war, a recession or earthquake. I didn’t think about a terrorist attack, a volcano or a pandemic, but I am happy with our choice, as I think the leadership we have experienced has been exemplary.

…and just as I write this, I learn that someone has died from covid-19 in Middlemore. It seems he has been in ICU on a ventilator for some time. It is very sad, and underlines how much we need to control the virus until we have effective medicines and/or a vaccine.

Security & Networking for cloud integration – SDP

It is increasingly necessary to integrate applications across multiple datacentres and cloud environments.  To further complicate matters BYOD and home access need to be provided as well.  This problem transcends integration, and a solution for integration can be extended to secure web apps and mobile device management.

PaaS, SaaS and IaaS provide different secure networking solutions.   They all work well in the simple case where you have one *aaS solution connected to your secure network.  But these days people need to have multiple solutions connected with any number of interconnections.

An example I have to work with has integration provided in an AWS VPC which has a VPN connection into 2 datacentres, peering with another AWS VPC, a VPN to another SaaS provider and a VPN to another VPC in Azure.  The IP addressing ran out in the VPC and it had to be moved to another (larger) IP range.  This meant duplicating all those VPNs.  Each VPN required engaging with a different network provider in turn and it took several months to finish the whole project.

Adding DR doubles the number of connections required for each Datacentre duplicated.  So in the above situation a full DR solution could require 25 VPNs.

Each connection into a component in a datacentre requires a firewall rule to open up the port, and routing can get complicated.  It can be improved by adding a gateway component in the datacentre.  The gateway component handles all the traffic internal to the datacentre and can do simple protocol conversion.  This simplifies routing and keeps all the connection rules in one place.  The gateway component can be just as secure as a firewall and is a lot more flexible.  The gateway component can refuse non-SSL traffic and then it removes the need for VPNs.

This gives a pointer to what a more comprehensive solution might look like.

There are a number of rules that apply to cloud networking

  1. TCP/IP is flexible and scales well but provides poor security.
  2. Any *aaS provided networking security option reduces flexibility to integrate with other providers.
  3. VPNs do NOT scale.
  4. Firewalls are very good at blocking agile delivery processes.
  5. Any security solution needs to provide/utilise Identity and Access Management.
  6. One layer of (state of the art) encryption is sufficient for most purposes (no need for SSL across VPNs).
  7. A solution that combines IAM with encryption and firewalls across the internet gives the security of VPNs & firewalls without many of the downsides.

The answer is provided by some sort of Software Defined Perimeter solution.  This is an emerging standard with some players providing good tools.  Access is managed by user or device, with all configuration in one place (e.g. LDAP).  There is no need to manage devices separately from applications.

SDP uses identity to control network access.  A controller provides a grant token to a specific user.  The network denies access to clients without a valid and applicable token.  An existing network can be brought into SDP with an SDP-aware gateway device.  Cloud providers (e.g. Azure) can offer SDP built into platform.

One advantage of SDP is you can have overlapping security zones and use standard internet protocols to provide infinite flexibility and scale.  An individual component can incorporate its own SDP controller or an SDP controller can control access to all nodes within a secure network segment.  An SDP controller can be part of several perimeters simultaneously.

Single Sign On (SSO) can be baked into the solution for no extra cost.  The access token identifies the user and the same claims that provide network access can also authorise individual services.  On the other hand legacy services with their own identity solutions will still work in an SDP without using SSO.

It may be some time before enough *aaS providers provide compatible solutions.  An SDP can be built from existing components, but an integrated solution is easier to manage.

I haven’t managed to implement this for any of my clients yet.  It is not just a question of putting in the infrastructure, but it is also a change of mindset.  The network providers have to let go of the idea that they can control security with firewalls and IP-based whitelists.  Identity management becomes central to security as it should be.

Time Travel

My humorous speech this year.  Good enough to win the club contest, but not placed at area contest.  (At least I won the area Table Topics contest as consolation)


I am a time-traveller.  To prove it I will go forward in time and see who will have won the upcoming election.  The process will take about 2 days.

One thing I cannot do is come back afterwards to this present and tell you the result.  You will have to travel through time along with me and learn it at the same time as everyone else.  In other words, you will have to wait.

Contest chair, Fellow toastmasters and especially the esteemed judges.

Time travel, also known as chronomotion, is real. We all travel in time and all only in one direction.  Sometimes we may seem to be travelling faster than others and sometimes we have a temporal head wind and the transport from one time to another seems very slow. We go through time faster as we get older.

We are sometimes happy about the passage through time. We say “time heals all wounds” or ”in the goodness of time”. Mostly we seem to resent it.  We talk about “saving time”, “the race against time” or even “the ravages of time”.  Some of us dream of being able to “turn back the clock”.

To really turn back the clock would require a time machine like that envisaged by HG Wells,   or the Tardis of Doctor Who, or Harry Potter’s time-turner. If you do go back in time you have to be careful of changing your own history. In “Back to the future”, Marty McFly almost prevents his parents’ marriage which would have had existential implications for him.

One possible complication of time travel is a man could travel back in time and father a child who grows up to be him.  In that case he is his own father and grandfather and great-grandfather,… and so on.  Robert Heinlein wrote a story where the hero was father AND mother to himself.  Work that one out!

Fictional time travel tends to get complicated but in fiction, the paradoxes all seem to be resolved by the time traveller not changing the past, but actually enabling the present.  They act as they need to act to make the past line up with their experience.  Harry Potter went back in the past and summoned the patronus that he had seen before at the same time.  Nothing actually changed.  This is because fiction has to make sense.  We all know that reality is not so constrained.

So! what if we really could control time?  We could read next week’s newspaper to see the election result. Or would we look at the stock prices, or lotto numbers to make wise investments.  We could travel back in time to significant moments in history to meet the heroes or villains.  Or we could rescue extinct animals from the past.  Imagine having Moa in the Zealandia sanctuary.

Many of us would like to go back to fix some mistakes we have made.  Think of all the embarrassing moments that could just disappear.

At least it would be nice to be able to skip the boring bits.  Imagine going to an airport 2 hours before your flight, checking in and then immediately getting onto the plane as it is about to take off.  No wandering aimlessly among the shops, staring out the window at other people’s planes taking off, or drinking endless cups of coffee.  It would of course, not be welcomed by the duty free shop owners, which rely on a captive audience to attract our money.

But! Is it possible to change the flow of time?  Physics says the answer is a definite maybe.   There is nothing in the laws of physics that says time has to travel only in one direction.  It is possible that somewhere in the universe time runs backwards and all we have to do is travel there.

Wormholes are tunnels that connect two parts of the universe together, Like the Mt Victoria tunnel, the two ends might be in different places, but they could also be in different times.  We could travel through the tunnel and instead of finding an airport, we could see a swamp with Moa running around. Wormholes seem to be possible, but they would require enormous energy which could only be provided by harnessing the gravity of black holes. Unfortunately there are no black holes in New Zealand, apart from perhaps the airports’ duty free shops.

The possibility of time travel does interesting things to the language.  How do we talk about an event that occurred in a past time, but later in our personal time line? Did it happen, or will it happen, or will it have happened, or has it will have happened?

After coming back from a trip to the future do you tell people about the things you have seen will happen?

Can we we say we saw something next week, or promise we will do it yesterday?

If you meet yourself in another time what form of address do you use?  Is it appropriate to address yourself as “you”?  Or is it “Hey me”?

I can’t rule out the possibility of time travel, but I can confidently say that humans will never master the ability to travel backwards in time.  I know that humans will never control time because I know that humans cannot be relied on to control ourselves.  If we ever will have developed the ability to travel backwards in time then someone has will have misused it and travelled backwards and sold the technology to the future past.  That means that if time-machines ever exist then they will always have existed. You couldn’t hush that sort of thing up!

So now my time is up and I should teleport back to my seat one step at a time.  We have all travelled 7 minutes during the course of my speech. Isn’t the future a wonderful place? I hope that I have used my time wisely and that you will not think that I have wasted yours.

Toastmasters speech on voting

“Democracy is the worst form of government,…  except for all those other forms that have been tried from time to time”

Fellow toastmasters and welcome guests

This quote from Winston Churchill evinces our love/hate relationship with voting and government.  There are many forms of governance with various levels of participation from Anarchy to Dictatorship.  Our form of representative democracy gives us very little control over decision making but it has one big advantage.  The possibility, probability and perhaps even certainty of regular and orderly changes of government.  Because there is nothing that keeps a government in check more than knowing that sooner or later they will become the opposition.

Over the next 7 weeks we will have the chance to decide who we want to govern us for the next 3 years.  This is our only chance to have our say, because after the voting is finished we go back to being passive recipients of government decision making – good or bad, competent or incompetent, benevolent or malevolent.  So how can we decide?  Are we hard-headed rational actors, or do we decide based on feelings?  Do we like a party’s policies or do we even trust them to follow through?  Do we know who is on a party’s list, or do we just vote for the leader?

Restructuring has hit parliament and the MPs are having to re-apply for their jobs.  The roles are open to anyone.  Now the parties and MPs are presenting their CVs and turning up for job interviews.  It is a 3 year contract with likely extension if they show competence.  The unsuccessful candidates will have to wait another 3 years to apply.  Anyone who has served on an interview panel will know what to look for in a candidate, and what can go wrong if you choose the wrong person.

Democracy is hard!  It is up to us to put some effort into the choice.  If we go into the ballot box with no idea how we will vote then we are failing in our duty.  We have not prepared enough and are likely to make an ill-considered choice. If we don’t bother to vote because we can’t put any attention to considering the options then we deserve any negative consequences.  We have seen overseas with Brexit, Duterte, and Trump that elections can make a big difference.  We have also seen elections where there is no real difference as the ruling party doesn’t allow it.  Luckily in New Zealand none of the choices are likely to lead to disasters, but the parties vary enough that voting does make a difference.  So it is worth our while putting some effort into the choice.

As toastmasters we should be listening to politicians’ speeches and evaluating them.  We want to know how they are trying to manipulate us.  What rhetorical devices are they using?  Any awkward alliterations? Advertorial style metaphors? Hyperbole, puffery and exaggeration? Do they repeat themselves again and again and again and again? Is understatement likely?  I think not!

Are they appealing to our minds, our hearts, our souls or our stomachs?  Or do they appeal to baser emotions: fear, envy, greed or hatred? Are they concealing something?  Are they trying to fire us up?  Or put us to sleep? We should also be thinking about our listening skills. Are we hearing what they are saying, what they are implying, or what they are keeping silent about?

Do we remember what the government promised 3 years ago?  Have they delivered?  What are they promising for the next 3 years.  What are the other parties promising?  Do we trust them to deliver?  What happens if circumstances change? (a war, a recession, an earthquake perhaps), who do we trust to be capable, flexible and honest?

I urge you to go out and listen to the candidates, read their manifestos, read the commentaries in the newspapers and talk to people you trust.  You should have the opportunity to meet your local candidates.  Go out and engage them in conversation.  Most of them will be quite different in person to what you see on TV.  Ask them the hard questions.  Listen carefully and respectfully.  No matter whether you like their policies, pretty much all MPs go into parliament wanting to make things better.

You might choose to stay away from political blogs.  They will typically be biased in favour of or against some parties.  The comments could make you want to give up the thought of voting.  The newspapers, radio and TV DO have some bias.  Try to recognise bias, and think around it, but also remember that it might be you that is out of step!  There are good objective and well researched commentary sites, but really you should go to the sources (the candidates and the parties) and make up your own mind.

If you find someone or some party that you really want to be elected then think how you might help them.  Consider joining the party or donating.  Volunteer to help them with mailing or door knocking.  Put up a sign on your front lawn and be prepared to talk to your neighbours about your choice.  As a member of a party you get to do some work, but you also get to have some say in what gets done.  Use your toastmasters’ leadership skills and join the local committee.  Or better still use the speechmaking skills and become a candidate.

Most of us will not display that level of commitment to any one party or candidate.  But still we can carefully weigh up the differences.  Is it tax cuts or welfare?  Business or environment? Regulation or deregulation?  The differences are not always clear,  but we should be clear about what we are looking for to be able to choose the best representative for us.

How do the promises of the various parties match our own morals and philosophies?  What have they done in the past that has gone well or badly?  All of us will have our own core concerns.  Do we value honesty or are we prepared to accept being lied to for the sake of getting things done?  Do we value openness in government or do we accept that the government knows best and doesn’t need to share the details.

Some people will say that it doesn’t matter who we vote for, because they are all liars, and they all put themselves first.  “Don’t vote it only encourages them” some might say.  But I think this is cynicism and just encourages the worst practices.  While none are perfect, there are differences and you can choose to vote for the ones that best match your values.  Competence and ability are required, as also are passion and respect.

In New Zealand we get two boxes to tick.  One vote for the local candidate should go to the best candidate, regardless of what party they come from.  Feel free to split your vote if you want!  The second tick is for the party.  Remember that the party vote determines who is the government, so be careful who you give that to.

You may decide that no party or candidate is worthy of your vote.  Think carefully about this.  We don’t expect politicians to be perfect.  They are human after all.  If you object to them all then perhaps you may choose not to vote.  I would recommend going into the voting booth and writing “no confidence” on the paper.  It will be recorded as an “informal” vote.  It doesn’t count.  It will go into the same box as those who intend to vote, but make some mistake.  However it is recorded, and is not the same as just not bothering.

In other countries, in other times people have had to fight for democracy.  In other countries, in other times ballots are accompanied by bullets and voting is dangerous, yet still people risk turning out to vote.  In other countries, in other times people have carelessly given up the right to vote and then suffered the consequences.  We are lucky.  We can vote for the candidate of our choice without any risk to our safety or employment.  Not voting would be disrespectful to our predecessors who fought for our rights and to those in other countries who would love to have our power.

The election is not really for the candidates.  It is about us and our chance to influence the next few years in New Zealand.  This is our chance to make a difference.  The candidates are working hard to be noticed by us.  The promises, the candidate meetings, the debates, the hoardings, the pamphlets, the kilometers of travel, the door knocking is all for us.  They may ignore us for the rest of the 3 years, but now is our time.

Remember! We each have one vote, so use it and use it wisely.
