The situation of excess males shouldn't be a problem.
Someone has already suggested same sex marriage.
What about polygamy? A woman could engage with two or more male partners. I believe that Mongolian society pratices this arrangement, why couldn't the Chinese? I also believe that polygamy exists within Australian society already as well. In the past history of China, polygamy was an accepted practice.

Australia and the west in general face the opposite issue. Due to endocrine disrupting chemicals (EDC) (for more information google "tedx" or "our stolen future"). EDC's in pregnant females cause male foetus not to survive full term. We can already see this in the national stats, births. In the future for at least the next 2 generations there will be declining numbers of healthy fertile males.
Why do you think Governments in the West are pushing females so hard? Perhaps because our Governments are really nice people. Lets get real.

My understanding is that the DOS attacks that are called
by the Botnet can come from everywhere in the world as the program
gets installed on any computer user who clicked on an unidentified link
in an email. Then when its master calls them up they all come to life
and attempt to connect to the specified URL address.

As far as Chinese policies, perhaps their 9 dash seizure in the Sth China Sea
is more related to their peak in coal production that has already
occurred together with the state of world wide oil production, means
that they are concerned to ensure oil supply in the future.
It is known that there are likely prospects in the area.
The well they drilled a couple of years ago in Vietnamese economic
zone against Vietnamese objection is said to have been dry.
However it may not have been and has prompted the current seizure of open ocean.

Yep, both your paras possible Bazza.

Hi Bazza

I've thought more about the Census Denial-of-Service (DoS) of 9 Aug 2016. Basically how would a US Intel Agency view it...

DoS doesn't have to be intentional. It can happen merely because too many people, through their PCs, try to access a site all at once.

If the equivalent of short-term Random Access Memory (RAM) is so configured for a "Mainframe" that is not programed to accept so many users all at once, then the Mainframe "Denies" to "Serve" any of the users. It is perceived to "crash".

Users in locations all over Australia automatically go through US-based servers (eg. at *) to access sites back in Australia. That is why people at internet security agencies in Canberra would have perceived a spike in traffic (around 7.30pm #) from the US to the Census site in Australia.

# A particular problem I saw on the night was that after the 7pm TV news reminded poeple to fill out their internet Census a high simultaneous number of Aussies tried.

I saw that the Census site was not simply Crashing at my first attempt (first 10 seconds or so) which would have "cleeared the deck" for more lucky users. Instead the site was allowing 10 to 20 automatic "redials" every 10 seconds or so.

If there was millions of Aussies trying around 7.30pm then that would therefore register as up to 1,000,000s x 20 near simultaneous attempts - which would Crash almost any poorly planned Mainframe RAM.

* many US servers eg. Google and Microsoft, are at Mountain View, Sunnyvale, California http://en.wikipedia.org/wiki/Mountain_View,_California#Top_employers serve internet users from all over the world

So the ABS Census Mainframe couldn't handle what was perceived to be 5,000,000 x 20 = One Hundred Million near simultaneous users at 7.30pm on 9 Aug 2016.

Shows how a Technical Problem becomes a Political Problem for Malcolm, already governing on a knife-edge.

Centrelink and Census with crashes? I demand that the next Census asks "how many Gov dept nets have crashed under your keyboard in the preceding 6 months"
