So, this morning I was having a retro moment and wondered about the original Xbox, the classic one from 2001 which was so popular. It was build on a pseudo Windows system with an Intel processor. Then I remembered the PS2 slim which was reintroduced long after the PS3 had taken over as Sony’s flagship and how Sega have also licensed their technology to create retro clones.

If we look at the Xbox1’s original specification:

CPU: 700MHz Pentium III Coppermine
RAM: 64MB DDR1 @ 200MHz
GPU: Custom NVidia ASIC @ 233MHz
Audio: NVidia custom Surround Processor
Storage: 8GB IDE HDD
Optical: DVD-ROM
Security: Secure BIOS
Extras: 100Mbit Ethernet, Analogue Component HD, USB1.1, and other AV connectors

So, when you compare this to the CE 3100 from Intel, which is being used by set-top box vendors to build the next generation of multimedia products, you find some interesting parallels:

CPU: +800MHz Pentium-M
RAM: Up to 3GB DDR2
GPU: Intel GMA500 (PowerVR SGX 535)
Audio: Dual core 337MHz DSP processors
Storage: Flash or SATA
Optical: DVD via SATA
Security: Crypto-processor
Extras: GBit Ethernet, HDMI, USB2, and other AV connectors

So, Dear Microsoft, why not ‘Reload’ the old XBox classic as a new product and get some revenue from that old architecture? The CE range supports DirectX 9, so there should be legacy support for the graphics calls. I don’t know how the GMA 500 compares to the Xbox1’s custom ASIC but they are 8-9 years apart in development so they can’t be too different. If there are differences they might be resolved with a bucket of faster DDR2 RAM and the better CPU clock.

I would imagine an XBox Reloaded spec would look something like this:

SoC: Intel CE3100
RAM: 256MB of DDR2 @ 800MHz (a bucket extra useful for other things)
Storage: 8GB of Flash (shouldn’t need more, but can utilise USB 2 flash or HDD)
Optical: Slimline DVD-ROM
AV: HDMI, TOSLink, Composite
Networking: 100Mbit ethernet (GBit might increase power/cost)

The whole thing should be able to emulate the Xbox’s original design without much special assistance, just the addition of SATA support to the microkernel, modification of the security mechanism and replacement of the graphics drivers (the highest risk element). If there was any problem with this it might even be possible to use a microkernel bootloader or BIOS to emulate the IDE on SATA in legacy mode and possibly even map the GPU calls. I would put a bootloader on the box which booted a version of MeeGo Linux stored in Flash as an alternative media player tool and possible DVD player alternative function.

Thus you would have a decent media player, a TV browser and a most importantly of all: a very cool retro-games console capable of playing games like Halo, Project Gotham Racing, MotoGP and Splinter Cell. All for under £100 retail! I know you can get a new Xbox 360 for £160 but there is always a market for the retro and a lower end product. The return on investment could be good and it could reach new markets as a “computer for all” in developing markets!

So, I was reading an article which described how a penetration testing company managed to get past a firewall by posting an employee a specially 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 Service and the 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…

OK, I had this idea a wile back and I finally got round to designing the concept, I don’t know if it would fly, but I think it is quite neat. Fundamentally the principle is that people in rural areas are pretty much excluded from the e-Cash revolution on the basis that they don’t have the infrastructure. By rural I am most interested in the way in which people in small villages or remote locations interact, especially in developing countries. We don’t have a means by which we could eliminate currency in their domains, we only have solutions for client server architecture in rich urban settings. Also the proposal for NFC is being built around expensive smart-phones which also doesn’t help the poorer in society. So I designed a device which should be cheap (~$10) and which can be used without being dependent on infrastructure.

I did a PDF to illustrate the Portable Currency Device concept.

More than a month ago now I announced my departure from Humax as their Chief Technologist. I have since been working for nice company doing some productisation work and while that has been interesting I have missed my colleagues at Humax. Recently I was called by my former Director, we had some discussions and after some careful negotiations I am returning to Humax. I am now to be a member of the development team and as part of this I will now be working more in Korea than before. It is a nice step-up for me and I hope I can input some valuable effort to the Humax development process. My departure from Humax was part of my personal development and I think it also gave a number of parties opportunities to consider approaches. This year is, so far, not only a good one for me but also I think this will be an important year for the companies I work with. The development of the YouView set-top boxes in partnership with the TV industry will be a minor revolution for the market place and Humax is well placed to take advantage of that through foresight and determination to lead the UK TV market. Furthermore I am also looking forward to working with freesat to bring their ambitions to fruition and I think that working together with them Humax can help their platform really evolve.

Here’s to the next step!

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 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.

Today I saw on Facebook a campaign for “European Revolution” on 29th May 2011 seemingly started by some Greeks, I saw this and thought how stupid this is. Thus here is my response, I thought about posting it on their wall but realised they would probably just divert some of their negative energies at me causing me grief, but I trust it is safer to put it on a website that almost no one reads (mine):

Clearly a group of people with too much time on your hands. The power for real change isn’t in protesting, it is in acting in a positive way: it is about producing, it is about helping your country to recover. You are the government, the people have the power already. You blame the economic and political forces? What have you been doing that lets these forces control your lives? The answer is: Nothing. Politics is of the people, you and your families vote for the politicians. If there is corruption then you let it happen by not paying enough attention to your representatives. If the economic forces have controlled your life then you have forgotten that by earning money you, as the people, are in control. The way you spend your money determines the fate of the economy and the nation. You might think that your money is less important than the money of big business but then you are underselling your own importance. If you campaign for a positive change in spending, and if you are in the right, then you *can* make a difference.

 

Of course some will attack me for saying this, but I have seen what these protests achieve: Nothing. Because they are nothing but a forum for violence by anarchists who want to feel ‘something’ in their lives through this violence.

The Greek people in particular need to take responsibility for their national situation.  You are not victims, you are complicit in the situation.

 

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 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.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:

If you’ve ever seen full frame uncompress 625line SD with component 10-bit colour then you will know that sometimes resolution doesn’t matter. At a previous employer of mine we could show normal people pictures on a Barco Grade 1 monitor and they would swear it was HD. Freeview just has poor quality because the cost of carriage is so high, especially when there are a dozen versions of BBC One or ITV1 and they have to compress everything down to the n-th degree. The reason that regionalisation costs money is that we must have a cellular transmitter design, each region has it’s own frequency (or more than one because of relays), adjacent regions can’t use these frequencies because otherwise that would affect coverage. The UK design has many “guard” frequencies to protect adjacent transmitters in this way. If every region had the same channels they we could uses a system called an “SFN”, or Single Frequency Network, in this configuration the transmitters all transmit exactly the same thing at exactly the same time at exactly the same frequency. When transmitting in an SFN if you are between two transmitters you get the signal from both transmitters, but instead of causing a problem for you it actually helps because the two transmitters actually re-enforce each other.
