So, I was reading an articlearticle which described how a penetration testing company managed to get past a firewall by posting an employee a specially rigged mousespecially rigged mouse! The idea was that my embedding a micro-controller in the mouse which could be programmed to disable the virus protection on a computer and then load some Trojan vector. The real difference in this design was that it didn't depend on a USB memory stick and autoload, it used HID keyboard commands instead.

One of the comments in The Register article made me think, the suggestion was basically this could be more than just a mouse. That had me thinking:

Why not put a 2G modem embedded in the keyboard!? Not just a dumb one, but one programmed to accept an incoming connection or create a reverse connection to the hacker. An mbed processor could act as the infection vector controller, or perhaps even one of the modems with embedded python-on-a-chip just to make it neat?

Then wow, that is a really big security risk and not that difficult to achieve. OK hackers, you have your next project, get going!

There have been a number of articles about the National Health Service's IT over the past 24 hours, most of them are about the LulzSec security breach (some of them mention how helpful LulzSec have been but most focus on the negative). But there have also been articles about the NAO report on the Ambulance ServiceNAO report on the Ambulance Service and the Socitm reportthe Socitm report as well. The Soctim article got me to I thinking that the NHS should follow the example of nebula.nasa.gov, they are building a cloud infrastructure specifically for NASA and it's dependencies. Then NHS departments could just bid for server time and be charged appropriately. Here is my proposal, it is probably poorly informed and politically impossible, but that has never stopped anyone writing a blog before! Read more bellow...

The State of Education and Authority PDF Print E-mail

Having previously worked in education and still maintaining an interest in life-long learning I find it interesting to read what people have to say about the state of modern education. Regularly I see tweets and blog posts from the likes of @Euan and @MMetcalfe about teaching and learning. Not specifically from the aforementioned people, but one thing I often hear maligned is lecturing, the process by which teaching is done from the front and experience is shared, essentially lecturing to the audience. This is in compliment to the Socratic Method, in which lecturing is used with questioning to establish a pattern of feedback to measure student understanding and pace.

Recently The London Evening Standard has been doing a series of articles about literacy in Londonarticles about literacy in London and how it affects us. Apparently four in ten job applications are now rejected on the basis of poor grammar and spelling and I saw this in action when I was lecturing because I would mark reports that I could barely understand. I was occasionally told that I shouldn't mark a student down because of their ability with English but I never respected that view, if you can't communicate then you deserve a lower mark people need to be driven to success. I've often discussed this with friends and family, and it seems to me, and a few others, that one of the biggest problems that we are having today is discipline and respect. I don't mean in a Victorian punishment kind of way, but in terms of the way those in authority are respected, or not as it seems now. No longer are teachers and the police given the veneration that they need to do their jobs. Parents and guardians no longer tell their children that they must respect and obey teachers and policemen.

Now, I know there have always been disruptive students, there have been since the beginning of time, but once upon a time students knew who the boss was and these days it is politically incorrect to have a boss. I am not the most disciplined person in the world, but I know who is in charge and I like to think I also know how to take some authority when needed. Learning the basics of language really takes routine and practice, boring repartition and positive re-enforcement. Sometimes children need to sit down and try, and fail, and then try again because if at first we don't succeed... Looking from a far there is a great deal of effort going into finding 'alternative' ways to teach children, when actually if that effort was spent doing boring stuff then the children might learn the virtue of doing mundane tasks. Because there are virtues in learning to do mundane tasks that a person in authority requires you to do and you shouldn't always question authority.

Of course children need to be educated in critical thought, analysis and debate, I feel this more now than I have ever done, but they must also learn about self-discipline and motivation. In school my Design and Technology (metal and woodwork) teacher, who was very much old school, insisted that we couldn't leave the class at the end until we had correctly answered a multiplication-table question. This forced us to look it up and learn them, otherwise we wouldn't be able to leave and we would be a little embarrassed. Some might see this as bullying, I don't, I think it was a cleaver way of motivating us and remember this man wasn't a maths teacher he was just a man passionate about ensuring we had the right level of numeracy, which is more than I can say about some mathematics teachers I have known.

Perhaps I am getting more conservative in my old age (;-) but I look at society and the way that the suitability of employment candidates has fallen in recent years and I think it is a shame. I want the world to thrive and I don't want the Western states to become the new third-world. Remember that in many third world countries children can't all go to school but a child will do as much as they can just for the chance to be educated, yet in Europe they children will happily commit crime just to avoid going to school! So, I believe parents need to take an active role in ensuring that children respect teachers and uniformed authorities, this is quite controversial in itself and then I think teachers need to start concentrating on getting the basics sorted through routine not through time-wasting creativity. I feel teachers should be inspiring through their leadership and enthusiasm, not so much through dressing up and entertaining students, after all teaching should be engaging but it doesn't have to be entertaining. It would take years to get back into some sense of order in schools, but perhaps then students would start turning up at higher education who can actually write something which makes sense and companies wouldn't have to do remedial education for their students.

Also, testing and exams might not be pleasant and they don't represent everyone's abilities, but when combined with practical work and essays I think they are effective measures of students. The idea of not being competitive at schools is ridiculous, I want people to be acknowledged as being a bit thick so they can be motivated to succeed. I wasn't much use at sports, but discipline forced me to participate more than I would have done of my own free will and I even found some things I was good at in sports. Everyone has something they are good at, I believe this, but some people are better than others. This doesn't have to be a Plutocracy in which success is dictated by wealth, but it doesn't have to exclude people from doing well and it seems to me that it is unacceptable to push one group ahead because it might offend those who are less able.

That is my rant, you are welcome to it.

OK, any posting with religion in it is probably an unwise and dangerous thing to do but it occurred to me this morning that the computer market is much like organised religion and here I will lay out my reasons:

1) Microsoft = Christianity

Penitent religion that once dominated the social and political map of the world.  Increasingly depreciating in it's followers enthusiasm although many continue to attend the ministrations more out of habit than out of true faith. Many evangelical sects still exist, some have fractured from the core authority but they still believe in what it stands for. Some orthodox groups exist aside from the mainstream followers and still experience great attendance but without too much wider attention. Not nearly as influential as it once was and has made some serious mistakes in the past.

2) IBM (AIX or OS/2?) = Judaism

Some view them as the originator of a later much more popular group, others avoid the comparisons and associations. Still has a great many fundamental followers but that number is diminishing. Some followers only practice behind closed doors and outwardly show no signs of an allegiance. Others proudly show their support in the window at key points in the year. Well represented in the finance sector.

3) Apple OS = Islam

Often failing to recognise the origins of their group actually stems from a common route with other mainstream groups. There are a core of fundamentalists who insist their way is the only way and all other systems should come to their view or die. More moderate members of the group are satisfied with their choice in life, continue to worship with blind faith. It is the duty of followers to encourage those not following their path to join them.

4) Linux = Hinduism

A group with many deities and various ways of expressing a following. Often peaceful but occasionally a little dysfunctional, with some areas which maintain a legacy in a modern environment but functional most of the time as long as you don't try to take it in a direction it isn't prepared for. Having a style which occasionally mixes with other groups but to the casual observer from the outside looks intimidatingly different.

5) Embedded RTOS'es = Various native religions

Quite functional in their own environment and supporting the people with their needs. Often looks very different to the mainstream groups and can be incompatible. Smaller followings but often works well, in harmony with the environment.

6) RISC OS = Paganism

May have pre-dated origins within an unconnected population but was pretty much wiped out as travel and needs of users grew. Of little relevance in modern society but still practised by small groups. These small groups occasionally put on public displays in public spaces, to which some from other groups take offence and others look on with mixed feelings.

I've been following the growth of interest in Thorium as a source of energy, it seems to me to be one of the best ways of producing large quantities of energy in a consistent way with a balanced ecological impact. Baroness Worthington was Raised to the House of Lords in February 2011 and as an ecological campaigner she brings something interesting to the mix. She made her maiden speechher maiden speech in the House recently and having seen it I thought I should send her a message sharing my views. Don't know how it will be received by her (I used http://www.writetothem.comhttp://www.writetothem.com to do it) and if she will accept what I have to say, but without input Politicians can't be representing the people. Bellow is my correspondence for your consideration and yes I am terrible at finishing correspondence:
