MacOS Update Printer Hangup

Has upgrading your Apple Mac to MacOS Sierra 10.12.2 resulted in your printer hanging up? It seems that the upgrade includes a printer driver and or firmware update that causes an attempt to print failing with an error message:
stopped – filter failed
To fix this you need to get into System Preferences | Printers and Scanners.
The panel listing your printers has + and – buttons at its foot that let you add and remove printer drivers. Remove the existing one that is now misbehaving or simply reset the printer system to do so – a right click option. Then use the + to see the drivers available to you. Hopefully you will see one for your printer but it may have a different or longer name than it had before to make clear that it is a new version. Try it out – it worked for me. Other computers connected to the same wi-fi network and hence the same printer but that did not yet get the MacOS update may also have a problem that can be fixed the same way. I am assuming that the update on the first computer actually downloaded new firmware to the printer unbidden so the same fix up driver protocol works on the other mac computers!

Beware of statewide pet control in South Australia

South Australian legislation on dog and cat ownership obligations apparently comes into force at the beginning of the financial year on July 1st. It includes requirements for such pets to be both desexed and microchipped on a state-wide basis.

While for a limited time, desexed rescue pets will of course be available from animal welfare organizations but, within a generation of each respective species, people will be limited to very expensive registered breeds for pets for their kids. Given that exposure to pets (and dirt) in your formative years has benefits for your immune system and long term mental stability, this limitation is hardly of public benefit. Nor is it fair that the benefit and joy of new puppies and kittens be only available to the wealthy who can afford exclusive breeds.

Furthermore, every second old home in our leafy suburbs tends to have fruit rats unnoticed in their ceiling or underfloor spaces that harvest and store fallen fruit and kernels. They are mostly unnoticed because numbers are kept in check by people’s own or their neighbor’s pet cats without the attendant risks from baits and poisons. In country areas, whenever there has been a program to cull wild cats, a massive rodent plague has inevitably followed a year or so later, so the lesson is you meddle with established balances between species at some peril. My main point however is not about consequences to do with vermin. It is that vigorous implementation of the new law will have serious unintended consequences on the health and happiness of numerous young families with no way back – so seriously reconsider and moderate its trajectory.

Plastic Bags Ban

The ban on free plastic bags from shops, especially supermarkets, has had massive adverse consequences for the environment. Whereasbefore they offered biodegradable ones that mostly went to landfill, now they issue robust reusable versions that last forever and are often taken to beaches, parks, camping areas etc so easily migrate to streams and the sea. In the USA, supermarkets (like Kroger in Texas) offer either plastic or heavy duty brown paper bags that are strong, biodegradable, made with responsible materials, water-based inks and water-soluble adhesives from ethical sources.

I notice and commend the Kathmandu outdoor activities oriented chain of stores for now utilising the same style of bag!


An election is imminent in South Australia – which political party might offer to fix this here?

Vehicle Refuel Contingency Idea

Adelaide South Australia experiences all too frequent electric power interruptions that have  knock on effects to important logistics such as traffic light operations, petrol pump operation at service stations, mobile and NBN dependant  fixed line phone operability, and life critical medical devices. I would like to see some key service stations on important routes in or out of both urban Andy  regional centres provided with state subsidised standby generators connected to some pumps and even recharge points for electric cars & scooters. Battery backed traffic lights are needed on intersections on key routes too. RAA and like organisations could provide an online resource to tell the public location and current operability of such resources – particularly important as growing such resilience would take time. Uninterruptible Power Supples (UPS) for small devices and even wall mounted domestic battery banks fed by private solar & wind generators are increasingly popular – albeit still rather expensive and they have their own risks that must be managed. We do not want these things to themselves be starting fires during heatwaves! The Government needs to take an inventory of power critical private & public infrastructure and systematically plan mitigation paths for them. Prioritised funding contributions through the Emergency Service Levy mechanism would, if carefully modulated, also be in the public interest.

The recently opened new Royal Adelaide Hospital had a power failure crisis during an operation caused when a test of their UPS system did not revert to mains supply for an inordinate time after the test ended. Why did they even test the system while surgeries were in progress? Such tests ought only happen before the day’s surgeries are scheduled.

That lesson ought be taken account of for any UPS context!

2018 Adelaide South Australia Election Issues

These are the issues that most matter to me for the forthcoming state election in March 2018.

1. Street Lights in avenues need an extra lamp illuminating below tree canopies with especially dark often uneven footpaths. New lamps near street entrances could even incorporate recorded high resolution CCTV.

2. Ban taxpayer funded political ads unless opposing Side equally funded.

3. Stop scheduling roadworks in an area at the same time – no alternative route!

4. Retracting & Fixed Bollards in public spaces especially North Terrace and the new broad War Memorial footpath leading up to the War Memorial on North Terrace as well as at the forecourt for the new Oval and prominent churches such as St Peter’s Cathedral Church.

5. Prices of these bollards reported in the media seem exorbitant (threefold) compared to what is cited online – make sure public is not ripped off with current fervour about this.

6. State Government should stop selling off our infrastructure such as ownership of electricity distribution and conveyancing – makes consumer prices higher over the longer term! Why else would anybody buy them? Many people I talk to are increasingly angry about this! Our taxes built them over many years so it is not right that one generation of politicians sell them for a short term purpose!

7. Essential service resources ought be underwritten with a level of strategic reserve! The USA does this with fuel etc but we bet mere weeks supply will always be enough. Disruption of World Trade or Supplies for any unforeseen reason would have catastrophic consequences! Need to gradually build up reserves of petrol, natural & liquid petroleum gas, even fresh water in State!

8. Major routes out of the city need UPS backed traffic lights and clearly flagged generator backed petrol stations to facilitate logistic support in major emergencies and even evacuations.

Dual Citizenship MP Issue

Australian Citizenship & Eligibility as MP

When the Constitution was instituted, by an act of the Westminster Parliament, there was no concept of an Australian citizen – all Australians were deemed to be British Subjects and indeed even in 1947 this was true. How then could anybody born in Australia then or earlier have their eligibility to serve in the Australian federal parliament questioned? To serve even in the Australian Public Service one had to swear allegiance to the Queen so it defies common sense that potential UK allegiance disqualifies anybody!

Biometric Security Initiatives in Australia

The new Australian Federal Government security initiatives give rise to some disquiet as to whether or not they are both technologically premature and also too heavily weighted against citizen’s civil right to liberty guaranteed by the judiciary.

The use of currently primitive 2D photographic biometric database has far too high a risk of false positive matching that could unjustifiably land subjects in detention for two weeks with no notification to their families or legal representatives. Notification is forbidden even retrospectively under current national security legislation! We have thrown the baby out with the bath water!

Even more advanced biometric technology in the newer mobile phones and tablets frequently makes mistakes locking the user out – even without the influence of eventual degradation owing to appearance ageing or injury in accidents. A nose broken in a car crash can prevent you phone recognising you when you want to call for help!

Detention without judicial review ought not be allowed for longer than a weekend and even then without multiple independent methods of recognition and the involvement of human judgement and the application of criteria of reasonable cause.

Energy Crisis in Australia

Energy Crisis in AustraliaThe news networks are reporting a looming petroleum gas price rise of 60 % in the coming financial year. Electricity prices may double in consequence too. The Treasurer is warning the industry to not sell overseas at World Market Priced unless they reserve enough for domestic needs or he will block that trade. Is that even possible given that the Australian Constitution apparently prohibits nationalization or confiscation without fair compensation? Maybe the industry has legal advice to that effect that emboldens them to foreshadow big price rises? 

The USA, the great bastion of unfettered capitalism, have a strategic reserve for oil & gasoline that gives them a year’s worth of supply while Australia would be lucky to hold two weeks worth of petrol! Successive Governments exhibiting negligence on a monumental scale!
For a start they need to start incrementally, year by year, to build petrol and gas reserves in this great land so we too hold a year’s worth – within say five years. In particular, gas-powered electricity generation plants ought have dedicated gas storage facilities in reasonable proximity to their plants. The long distance electricity transmission lines are not only inherently inefficient with the losses ending up, as does all waste energy, as planet warming heat but they plan to build even more rather than locating small scale generation in proximity to consumption sites – perhaps even on moveable floating platforms that could be flexibly located. Any energy- resources export duty to mitigate the drain of reasonably priced domestic supplies needs to be balanced by some investment in developing our energy supply and deployment infrastructure too. Naturally a mix of electricity storage technologies should be incentivized too but all such steps really need to be incremental because shock therapies always have unintended consequences and technologies continue to evolve.
