Jealott's Hill Walk 'n' Wassail

Another good day at the Land Share with the Morris men.

I have scanned the sheet provided on the day - It got a bit crumpled and wet, but I think you can get the gist of the proceedings.


Some dancing outside the barn and then a procession over to the apple orchard to ensure that the trees remain fertile.





The Wren and Robin are symbols of the end of winter and the start of a new season.
A Morris man in a ragged jacket held up the Robin for all to see him still alive.


The Robin having been dispatched, a Queen is chosen. A cake with a hidden bean is distributed.
The lady discovering the bean becomes the Queen of the Bean.


Amazing! Bracknell's Deputy Mayor Tina McKensie-Boyle found the bean, and was lead out to receive the crown and select the King.



The King received his adornments too.


A devil is added, just to even things up.


All now proceeded to the tree where the King and Queen buried the robin and a refrain was sung.














A few links to information and news from the land share.

Car Technology Moves on the UK

Driverless cars.



There as an allusion to this technology in my book Cold Suspenders. The technology mentioned there is more about “safety” control, and would could happen if the authorities could override the control of your car (more than just speed limiting).


Britain is leading the way globally in the adoption of driverless vehicles on national roads. While countries including the United States, Japan and Germany are all competing to accelerate the commercial acceptance of autonomous transport, Britain has developed a national consensus and regulatory roadmap that others lack completely.


http://www.telegraph.co.uk/technology/2016/04/10/britain-is-head-and-shoulders-above-rivals-in-putting-driverless/?cid=sf24100241&sf24100241=1

Autonomous driving features, including automatic braking and lane-departure sensors, are becoming common. A recent study shows that British motorists choose to buy cars which have that technology as an optional extra Probably people are willing to pay more to gain access to enhanced safety benefits.


58% of new cars sold in the UK have some form of autonomous driving system in place, collision warning being the most common. 39% of cars now have emergency braking capabilities, and 32% have adaptive cruise control.

SMMT last year found that serious accidents could fall by more than 25,000, saving 2,500 lives every year by 2030, as a result of driverless vehicle technology.

How tax can be seen to work in terms of Beer.

I was reminded of this by a similar post on Facebook.
I decided to record it here, so that I can find it again.

Suppose that every day, ten men go out for beer and the bill for all ten comes to £100. If they paid their bill the way we pay our taxes, it would go something like this…
The first four men (the poorest) would pay nothing
The fifth would pay £1
The sixth would pay £3
The seventh would pay £7
The eighth would pay £12
The ninth would pay £18
The tenth man (the richest) would pay £59

So, that’s what they decided to do.

The ten men drank in the bar every day and seemed quite happy with the arrangement, until one day, the owner threw them a curve ball.

“Since you are all such good customers,” he said, “I’m going to reduce the cost of your daily beer by £20″. Drinks for the ten men would now cost just £80.

The group still wanted to pay their bill the way we pay our taxes. So the first four men were unaffected. They would still drink for free. But what about the other six men ? How could they divide the £20 windfall so that everyone would get his fair share?

The bar owner suggested that it would be fair to reduce each man’s bill by a higher percentage the poorer he was, to follow the principle of the tax system they had been using, and he proceeded to work out the amounts he suggested that each should now pay.
And so the fifth man, like the first four, now paid nothing (100% saving).
The sixth now paid £2 instead of £3 (33% saving).
The seventh now paid £5 instead of £7 (28% saving).
The eighth now paid £9 instead of £12 (25% saving).
The ninth now paid £14 instead of £18 (22% saving).
The tenth now paid £49 instead of £59 (16% saving).

Each of the six was better off than before. And the first four continued to drink for free. But, once outside the bar, the men began to compare their savings.

“I only got a pound out of the £20 saving,” declared the sixth man. He pointed to the tenth man,”but he got £10!”

“Yeah, that’s right,” exclaimed the fifth man. “I only saved a pound too. It’s unfair that he got ten times more benefit than me!”

“That’s true!” shouted the seventh man. “Why should he get £10 back, when I got only £2? The wealthy get all the breaks!”

“Wait a minute,” yelled the first four men in unison, “we didn’t get anything at all. This new tax system exploits the poor!”

The nine men surrounded the tenth and beat him up.

The next night the tenth man didn’t show up for drinks so the nine sat down and had their beers without him. But when it came time to pay the bill, they discovered something important. They didn’t have enough money between all of them for even half of the bill!

And that, people, journalists and government ministers, is how our tax system works. The people who already pay the highest taxes will naturally get the most benefit from a tax reduction. Tax them too much, attack them for being wealthy, and they just may not show up anymore. In fact, they might start drinking overseas, where the atmosphere is somewhat friendlier.

Priestwood and Garth, Facebook page.

Again; it is such a long time since I blogged. I suppose the coming of the next election has reminded me of keeping connected with people. I am a member of several Facebook sites, and have joined The Priestwood & Garth page at https://www.facebook.com/priestwoodandgarth . I expect to contributing there soon.
Priestwood and Garth Conservative team members.
 Graham, Alvin, Tina, aided by Jessica and Oliver.
The Priestwood & Garth Conservative Team have had regular walkabouts. The amount of walking about will be increasing soon when the election starts. We have already been out delivering good news about your Conservative run council. During the election period we along with the other parties will be delivering more literature.

Please read the literature that you get from Parliamentary, Borough and  Town candidates. This will help make your mind up as to how to vote.

Post Mayor Posting

It has been a long time since I last blogged. Partly because I have the duties of Bracknell Town Mayor to attend to. So; Here is the report; well most of the report that I gave at the end of my year as Mayor.

This year has gone much quicker that I expected
When I sat down to compose a report, I wondered where to start.
I thought, let’s have a look in the website; ….. what do we tell people that the Town council does? It says…. Our mission is:

To be the guardian of Bracknell Town’s parks, play areas and public spaces,
and to safeguard them from possible future development.
To be responsible to the needs of all sections of our community to build upon
our achievements and provide high quality services at minimum cost.

This is evidenced by our recent commitment to helping the community in creating a Neighbourhood Plan. More will be talked about that later……
Later this evening, the new mayor will be presenting this years grant cheques to various deserving organisations. It gave me much pleasure to meet, as Mayor, with a great number of the recipients of last years grants, and to see the hard work and dedication of their many unsung volunteers.

It has been my pleasure to support the repair of Holy Trinity Church Roof and Youth Rugby this past year.
A member of the Mosaic Church, that is affiliated to Holy Trinity, gave an excellent speech at my Civic Service earlier this year about the values imbued in sports that can overflow into our lives. Through discipline, control and mutual self-respect, a fellowship and sense of fair play are forged, …..this is a set of laws that fit well with everyday life.

That brings me to the facilities provided by the Town Council; recreational facilities that can be accessed by all. My thoughts are first drawn to Calfridus way in Bracknell, where Rugby youth practices, and where many improvements have been put in place by the Town Council.
Recent projects have enabled us to provide improved play and exercise equipment for Town residents. The Sports Legacy Zone at Mill Park applied the latest thinking in social fitness and multi-use sports area design.

There have been other improvements to the Town Councils Recreation and Woodland areas. These facilities have benefited from the attendance of our environment wardens. Two of The Town Council Parks have gained Green flag awards, signifying that they are among the top in the country.
Numerous events have been held by the Town Council over the year, one I much enjoyed was the Teddy Bears Picnic.

During my Mayoral Year I have enjoyed many events, and visits, and as I started to mention above, it has been humbling to meet so many enthusiastic volunteers in the Town Area, these are people that serve us every day. My thanks go out to all those voluntary organisations that help us all.

I much enjoyed the progress of Bracknell in Bloom last year; meeting the contenders; meeting the Judges; and helping to hand out awards to winners. I am especially proud of the Towns children, in Schools and at Scouts, and youth clubs, who contributed, and passed on their enthusiasm to their parents. I hope next year that with everyone’s help that we will yet again be in the top, if not top of the winners nationally.
I would encourage everyone to look at the BTC website to see the range of things that we do. And please do sign up to the Facebook page to keep in touch with news and activities of the Council.

I have not held that many fund raising events this year, for one reason or another,  but am grateful to the Grange Hotel for their handling of the Tea Party, and The Old Manor for providing at a huge discount the hosting of the gathering after the Civic Service.
I would also thank the staff at the Town Council, who have been most supportive, under the guidance of our Town Clerk Russell Reeve.

Back to more blogging soon...

Mobile Phones and Virus Issues

Antivirus programs are quite familiar to us on our desktops. As mobile operating systems have grown in
popularity, desktop type security concerns have followed. So trained are users that when Android antivirus apps began appearing, users saw them as a must-have. Given that there have been various bit of news about Android malware; users can’t really be blamed for making assumptions.
The trouble with apps is that they all run in the same sandboxed Java environment, which  includes the AV apps as well.  Most AV apps lack the ability to gain low-level system access on mobile that desktop antivirus would. This currently means that the best way to avoid malware is to understand how Android apps work.

When an app is installed, the system will always display permissions requested. See here  for an example. You can also find these permissions in the android settings for installed apps. These permissions are shown on a tab in Google Play) Some antivirus apps such as Zoner can display a list of apps and the number of permissions granted.
If a simple app asks for permission to send and receive SMS messages; that should be checked out by the user. Recent malware has been designed in such a way that by gaining rights to the phone, it can send text messages to premium rate numbers and also allow other attackers to carry out fraudulent activities. PC World reports that when first executed, Obad.a prompts users for device administrator privilege. Applications that gain this privilege can no longer be uninstalled through the regular apps menu until they are removed from the administrators list on the infected device. Indeed security researchers at Kaspersky’s lab have come across a Trojan virus, which is so strong that it might be almost impossible to remove.

The same problem exists for apps that allow phone calling permissions, potentially allowing them to call premium rate numbers without the user’s knowledge.

Another permission to check for is access to the contact list, and Google accounts. If you believe that the App should not be accessing this data, there is a chance that it is malware designed to collect user data for spamming or phishing. You might expect to see this permission is in apps that autocomplete contact names, or handle messaging actions.

The location permission could be used it for location-aware ads (might be useful), but a more questionable app could pick up a user’s location, and store it over time to sell that to advertisers.

The best way to stay safe on Android is to just stick to established apps from the likes of the official Android Market or the Amazon Appstore. While bad apps do occasionally show up in the Market, Google removes them swiftly and can also remotely kill the apps on phones.

There has been good evidence that a lot of free Android antivirus apps just don’t work, and could even cause people to believe they are protected when they are not. This might mean people taking take more risks with downloading dodgy software. There is a useful review here

Perhaps even worse is the latest scam imported from the PC platform, a form of which was recently identified by Symantec. Android Fakedefender locks people out of using other applications and can also change the settings of the OS, making it tricky for people to uninstall the malware.

Juniper networks says that the Mobile Threats Report, conducted by the Juniper Networks Mobile Threat Center, is one of the largest first-hand quantitative research studies of its kind. The report is based on analysis of more than 1.85 million mobile applications and vulnerabilities, up more than 133 percent from the last report released in February 2012.
Juniper says it's clear that cybercriminals are now rather than trying to crack into every system, are going after the most popular: Android which dominates nearly 60 percent of the smartphone market share. (Apple has slightly more than 19 percent and Microsoft has 18 percent.)

An interesting feature of Zoner mentioned above is the theft protection, which if enabled allows you to remotely control and locate your device via SMS messages. If you have lost it somewhere you can get a location or sound an alarm for people to notice it. (useful if you have left it on silent) If it has been stolen you will be notified when SIM is changed. It might also be used by your partner or others to track your location...

Yet more hackers?

In the Daily Mail Littlejohn says:
 "Law firms, telecoms giants and insurance companies all hired criminals to harvest sensitive, confidential information. One of the country’s most prolific hackers, a private investigator, admitted that 80 per cent of his work was carried out on behalf of lawyers, wealthy individuals and insurers.
Other clients of hackers included a household name who broadcasts to millions of people every week; another celebrity who paid a firm to hack into an employee’s computer; and a businessman who wanted to obtain intelligence on rivals involved in a £500 million takeover bid.
Investigators routinely obtained everything from bank and credit card statements to itemised mobile phone bills"

This was following on from a report in the Independent that alleges that a suppressed official report accuses respected industries of hiring criminals to steal rivals’ secrets. Yet an official report into their practices has been suppressed.

An interesting part of the hacking process in the operation "Blaggers" who obtain key information that may be used in itself or facilitate the hacking of another system. This is referred to on the Information Commissioners Office website - Reports to Parliament. the May  report bring up an interesting list.

"Following the report the Information Commissioner received a request under the Freedom of Information Act 2000 for further information about the publications that the 305 journalists were employed by and a breakdown of their activity. After considering the relevant exemptions information which did not identify the journalists or the publications was provided to the requester. Having considered the matter further the Information Commissioner has decided that a further disclosure is in the public interest and in the context of a special report to Parliament is consistent with the discharge of his functions under the Data Protection Act 1998. The following table shows the publications identified from documentation seized during the Operation Motorman investigation, how many transactions each publication was positively identified as being involved in and how many of their journalists (or clients acting on their behalf) were using these services".

Interestingly on the top of the list was the Daily Mail, with a reported 952 transactions and 58 journalists/clients.

It seems that illegal practices identified by Soca investigators went beyond the simple crime of voicemail hacking (see previous blog - Phone "Hacking" or Opportunistic Access? ) and included live phone interceptions, police corruption, computer hacking and perverting the course of justice.

GCHQ may gather 39 billion separate pieces of information, but how do you find the bit you might want? One should probably concerned about who could access that data.  

The trouble with access points is that once they are there, unless there is some kind of physical switch to isolate them, they may be vulnerable to unwanted access. Who also might be able to access the probes that GCHQ has placed on more than 200 transatlantic cables?

The other problem with people owning .com names is that the USA could claim that any traffic must be routed by way of the USA. See Extradition .com ‘wire fraud’ - Who next for extradition? 

The problem has been around for some time though - See Hackers’ ancient and modern blog post. There is a bit more about this sort of stuff in my book "Cold Suspenders". There are different types of suspender, and none of them hold stockings up.

Phone "Hacking" or Opportunistic Access?


A lot of mobile phone owners may have been worried by all the talk of “'phone hacking”. Customers often ask me what they can do to protect their phones, and what it’s all about anyway. In effect there is no actual phone hacking involved, it’s more of people taking advantage of lax security.

What we are talking about is opportunistic illegitimate access to voicemail messages. These could be mobile phone messages, or messages on a home answering machine.  Since the police inquiry into the News of the World scandal, mobile network have operators greatly improved their security mechanisms to increase protection of users.

A big problem with voicemails arose from the use of well-known default PINs for voicemail access. Most customers will probably have never have used their PIN code to access voicemail. On most mobile phones, the network recognises that it is your phone calling and makes life easy for you by recognising that it is you and replaying the messages.

Operators often provide an external number through which you can call to access your voicemail remotely, but the easiest way to pick up your voicemail remotely is to call your own number. Usually when in starts the voicemail message you can enter a PIN number to access the voicemail. On O2 the default used to be 8701. (You key a star first). I remember a friend of mine being horrified when I demonstrated to him how easy it was for anyone to listen to his voicemail.

As with computer passwords people who do set up PIN numbers often use their birthday or some other well known number that someone else could easily guess at. That makes it a bit too easy for someone to access your stuff.

Sadly there are now newer methods that do verge on hacking - These methods involve faking a phone’s Caller Line Identity so it can spoof access into voicemail. To block this type attack, you need to set-up a PIN to access your voicemail. By doing this you prevent automatic access to your voicemail. A bit of a pain to have to use it every time, but at least it make thing more secure.

I touched on home answering machines earlier – If you look at the operating instructions here. (See page 36 – remote access) They are much like the mobile phone set-up. Many people would leave the pin as the default 000 – a bit too easy for someone else to guess!

Soon I intend to blog about what the real hackers can do.

3D Printing a Revolution or an aid to Revolution?


Could we soon see governments licensing the use of 3D printers?

The printing of physical 3D objects from digital templates is becoming cheaper and more sophisticated. 3D printing uses an additive manufacturing technique to build up layer by layer from the bottom up.
3D Printing allows designers to create both everyday and complicated objects that in some instances would be impossible to make.  There is currently a limited range of objects that can be printed, but already cars, bikes, houses, prosthetic limbs, keys and guns have all been printed. As a backup you can have 3D printers to print more 3D printers.

http://usa.chinadaily.com.cn says that “One example of how 3D printing has influenced the arms industry is that, after the technology was used to make guns, they became more easily available. So countries have to take every possible measure to ensure that criminal gangs don't get access to the technology, because they can wreak havoc in society. Though China has a strict gun-control policy, the fact is that implementing the policy would become very difficult if it is easy for people to download gun designs and forge them with the help of 3D printing technology.”

The New Scientist talks of the US army's Rapid Equipping Force (REF). It has put together three mobile laboratories in 6-metre-long shipping containers. Each lab comes with tools such as plasma cutters and jigsaws, a 3D printer that prints in plastic or metal and a scientist and engineer to run them. The labs, which cost about $2.8 million, can be picked up by helicopter and set down just about anywhere. When the 54 °C heat in Afghanistan was playing havoc with the batteries in a ground-penetrating radar system used to search for mines, soldiers used a 3D printer to make a shielding case to protect them. Interestingly, printing weapons is not on the agenda, although fixing them might be.

In another issue of the New Scientist "HaveBlue", a member of the AR15.com gun enthusiast forum, which is named after a common semi-automatic rifle, claims to have carried out the first successful test-firing of a 3D-printed gun.
HaveBlue did not print an entire gun but only a part called the lower receiver, which serves as a frame for the other components of the gun. This component is the only gun part regulated for sale under US law and as such must carry a serial number - unless it's made by a private individual for their personal use, so HaveBlue is not breaking any laws. See also 3-D Printed Gun Only Lasts 6 Shots. (Also video here) at Wired.com Danger Room.

In a further article it is shown how High-security police handcuffs can be opened with keys made by 3D printing.

What other items could be made by 3D printing and what could the consequences be? I did touch on 3D printing in my book Cold Suspenders, but in the story the printer can only be purchased with a specific government ID card. Could this become a reality?

On a lighter note, an IET journalist sampled some printed food, and she says we might find ourselves traipsing into our kitchen, turning on our 3D food printer, and printing out our favourite dinner.

Weather or not


Whether you believe it is man-made or natural, some sort of Climate Change is happening, and probably always has.  It may or may not have a bearing on this having been a very wet year.

But anyway; in a recent IET article it is reported that the IPCC declares that climate extremes, or even a series of non-extreme events, combined with social vulnerabilities and exposure to risks, can produce climate-related disasters. Another IET article points out that recent terrorist attacks on infrastructure have highlighted the vulnerability of our rail and road networks, reinforcing the importance of good risk assessments to protect some of our biggest assets.

One could imagine that if Terrorists can predict disasters that they could then seek to exacerbate the problem. This is something that I explore in my book Cold Suspenders.

Extreme events can have a direct effect on people’s lives, potentially disrupting commodity prices, supply chains, markets, and economies. The recent wet weather makes the possibility of the events in Cold Suspenders look even more likely.

Following some links from the articles I came across the Startrans project “Trains, cars, buses, trucks, metros… are interconnected to create a network of transportation systems. This network, at the heart of our daily lives, fosters social cohesion and needs to be protected as a crucial asset. Terrorist attacks and security related incidents on transportation systems in major European cities have shown that the protection of transport infrastructure is long overdue. This is where the STAR-TRANS project acts: to understand how one incident localised in one single transportation system may affect the whole transportation network: the network of transportation networks. STAR-TRANS will produce tools analyzing how risk propagates and affects interconnected transportation systems in Europe.”

It would seem that some-one is looking into it, although the results from a similar project (DEMASST) are a long time coming.

There was an interesting short story contained in the November issue of E&T.  The year is 2050, the city is London. The landscape of the capital has changed radically after the decision-making process over the effects of climate change was taken out of the hands of engineers and put into the hands of bureaucrats.A London landscape altered by climate change.

Carers UK

I have just been downloading some pictures from my camera. It was pleasant to find pictures of the Carers UK event in October this year.

The event brought together carers present and former who have been with the organisation a long time. My mother has been a member of this organisation for some time. She did some quite heroic work looking after my father who developed Alzheimer's disease. 

The event paid tribute to the late Mary Webster, founder of Carers UK, and was held at Lambeth Palace, home of Carers UK’s vice president the Archbishop of Canterbury; Dr Rowan Williams.

Caring can take its toll on finances, health, career and family and social life. Carers can fall out of paid work and many rely on low-level benefits, forcing them into poverty. Without unpaid carers our NHS would collapse and the country would face an £119 billion care bill it cannot afford. More at  http://www.carersuk.org/ 

Data from the 2011 census shows a substantial rise in those caring for a relative or friend. There are now 5.8 million carers in England & Wales compared to 5.2 in 2001.

Baroness Jill Pitkeathley  trained originally as a social worker and led the carers movement for twelve years, creating Carers National Association (now Carers UK) and turning what had been a private, hidden trouble, the needs of Great Britain’s six million carers, into a public issue. She remains a Vice President of CarersUK. 




Amy Cook is a carer to her mum and sister as well a model and an active voice for carers across the UK.
Amy helped Carers UK get out the message on the ITV Text Santa appeal about how caring has touched her and her family and what help would make a difference.

Dual Cyber and Conventional Infrastructure Attacks Understood?


The Guardian says that for the first time the government  have admitted that firms providing "the essential services upon which daily life depends" have been subjected to attacks from abroad.

See also Power in Whose hands?

British officials will not comment who is responsible for attacks on UK, but earlier this year Guardian revealed the US was also worried about foreign powers mapping America's infrastructure ; The Pentagon pints a finger at "reconnaissance" work by China and Russia.

The BCS reports that the UK’s cyber security strategy has been criticised by a former US cyber intelligence officer for its lack of leadership and direction.

Bob Ayers, formerly of the US army and Defence Intelligence Agency, has questioned the structure of Britain’s cyber security program. He describes it  as “a collective of independent entities’ rather than a streamlined unit.”
A key criticism came from former GCHQ and CESG head Nick Hopkinson, who told Computing that the UK lagged behind the US, France and Germany in its ability to respond to cyber-attacks because of a "lack of cohesion" between the various organisations set up to work towards the strategy.
Comparing the UK's cyber programs to that of the US, Ayers suggests that Britain is decades behind and lacks the ability to produce ‘professionalised’ cyber security personnel.

The UK police now provide a central point of contact for information about fraud and financially motivated internet crime. If you've been scammed, ripped off or conned go to http://www.actionfraud.police.uk/

There should be an announcement by the Cabinet Office minister, Francis Maude, of new measures to protect people and companies from a daily bombardment of cyberscams and attempts to steal the nation's trade secrets.
Maude has suggested that cyber security capacity needs to grow globally, and cited the UK's centre of excellence on cyber security as an example of how Britain wants to help other countries by offering independent advice on building a secure and resilient cyberspace.

According to the Intelligence Security Committee the government does not understand the nature and extent of cyber-attacks from other nation states such as Russia and China, which are focused on espionage and the acquisition of information. This suggests that nations may never fully open themselves up to each other, as they are still some distance from being able to trust one another.

Are the implications of both dual cyber and conventional infrastructure fully understood?

Green energy held up by magnets and environmentalists?

Could the rising tide of wind farms be held up by green concerns.

Could it also be that Global warming will enable the magnets needed to be won from the ground?





What makes a good magnet?


Iron-based / ferrite magnets are cheapness abundant – But; you need an awful lot of ferrite to create a large magnetic field.

Better magnets have been produced by metallurgists mixing up promising elements and putting them in magnetic fields and seeing what happens.
Aluminium-cobalt-nickel or "Alnico" magnets in the 1930s produced  more than doubled the energy density of the best ferrites.
In 1970s the discovery of the magnetic potential of the lanthanide / rare earth led to Magnets made from a mixture of cobalt and the rare earth element samarium that can store more than twice the energy of Alnico magnets.
In the 1990 magnets made of the rare earth element neodymium plus iron and boron produced a magnet the size of a fingertip that could create a magnetic field several thousand times stronger than that of Earth's iron core.
When the likes of Neo was invented It drove up demand to the extent that the availability of rare earths is now a big problem.

Why do we need good magnets?

Huge quantities are being used in green energy technologies; Such as motors/generators for wind turbines, electric cars and bicycles. These have to be both powerful and lightweight. It is only Neo magnets give the performance needed.

Every motor in an electric car needs about 2 kilograms. A wind turbine capable of producing a megawatt of power needs about two-thirds of a tonne.

The demand for Neo magnets for wind turbines is projected to increase more than seven times by 2015.

How can we get more?

The US Department of Energy has a project called REACT Rare Earth Alternatives in Critical Technologies". Its aim is to come up with magnets that use less of rare earth elements or perhaps none at all.

Up until now most of the world supply of rare earths has come from China. Increasing though China wants the elements to use for itself.

In Canada Quest Rare Minerals Ltd holds one of the largest heavy rare earth element deposits in the world but it is located in an unforgiving northern part of Québec where, oddly enough, Global warming may allow access through the permafrost.

The possibility of mining in Malaysia has been dogged by criticism from environmentalists and residents; Opposition that has galvanized a "green" movement in Malaysia.

Money - decus et tutamen - how do you wrap it up?


Some time back I was Blogging about “Money without Banks” I was prompted to look at this again by some one calling about the vagaries of the current banking system and Governments.

One line in the editorial of the New Scientist from June 2011 says “While fraud is still a concern, the financial collapse of 2008 has called into question the competence of the central banks that are supposed to manage national currencies.”

 In November 2012 the editorial is again discussing something similar in the form of Bitcoins. This time there is another interesting line: “Like all truly disruptive technologies, Bitcoin is hard to conceptualise at first. But "fiat" money - the kind we use today, based on pieces of metal and paper whose material and face value have long since drifted apart - was once baffling, too.

We have yet to see whether governments and banks will step in to stifle the possible evolution of new peer to peer currency. But one way or the other things could be changing.

In an article on the Bitcoin the New Scientist says that the European Central Bank has taken interest, last month publishing 
a report on virtual currencies. It says such currencies will have little impact on real-world financial stability for now, but if the popularity of Bitcoin and its ilk increase, central banks may have to start regulating them. One wonders what form this “regulation” would take.

Where will the smart money go? Can (over) regulation be avoided?
