A free offering for World Choi Kwang Do week

This week is, for our martial art, Choi Kwang Do, starting to be known as World CKD week. Primarily that is because March 2nd is the anniversary of Grandmaster Choi founding the art, originally in 1987. The week is being themed with the tag line Science meets Martial Arts. This is one of the main reasons Choi Kwang Do works for me. In class we learn, practice and teach things based on the reason they work.

I have written about our family’s martial art of choice many times and my exploration of technology in the art and how I arrived at the art via technology and serendipity too. There is also the more formal article in my writing portfolio about Virtual athletes
All this has led to Choi Kwang Do being a huge part of our family life and we have made so many good friends through it. There is a bond we all feel in the positive spirit of the art. It was shown this weekend as we celebrated with Master Scrimshaw the 5th Anniversary of BasingstokeCKD Our dohjang was full on Saturday with fellow students from Basingstoke, but also some good friends, old and new from other schools. We had black belt tag grading, colour belt grading, an incredible set of routines to go through in class and then a great social event with food and cakes. It was incredibly uplifting, and an ideal lead into World CKD week too!
To celebrate this World CKD week I have made Cont3xt free to download. It has an awful lot in it, pivotal to the story inspired by Choi Kwang Do as an art and a state of mind. It fits with the Science (Fiction) meets Martial Arts tagline for the week. Whilst I am doing this to encourage my fellow practitioners to see ways we can introduce Choi Kwang Do in many different ways, and as a way of saying thank you to them all there will of course be other people able to download and experience the books for free. All my author bio’s mention Choi Kwang Do.
We pledge Humility and Integrity, amongst other things, in the art. So promotion of one’s own work like this could feel a little uncomfortable. However I really want to share how CKD inspired elements fit into a science fiction techno thriller in a very positive way. It was the just getting on with it unbreakable spirit that we learn, that even got me to write these two books.
As Cont3xt is the follow up book I have also made Reconfigure free for the week too. The martial arts arrives in Cont3xt but not in the way you might think to start off with, in Reconfigure (book 1) Roisin has no such skills, but the book is there for free too for completeness.
I hope a few people get a chance to take a look, maybe even pop a few stars of reviews on Amazon. I would also love for someone to have read the Cont3xt, who doesn’t do CKD yet, and to look up the art , find their nearest school and start to train. It’s a long shot, but every person in the World is a potential student to join us, have some fun and learn something really useful about themselves.
Choi Kwang Do is practical self defence, but we aim to never need to use it, and we also don’t fight and hurt our fellow students via competition and sparring. I believe the quote is “It is better to be a warrior in a garden than a gardener in a war.”
So there we have it, the books are available free on Amazon, to be used in whatever way works for whom so ever needs it. Cont3xt and Reconfigure here.
Pil Seung! (Certain victory)

Lucky 7 years – Feeding Edge birthday

Wow. It is seven years since I started Feeding Edge Ltd. That is quite a long while isn’t it? The past year has been a more difficult one with less work in the pipeline for most of it. It has meant I have had to take stock and look to do other things, whilst the World catches up. It does seem strange given the dawn of the new wave of Virtual Reality, and Augmented Reality that I have not managed to find the right people to engage my expertise and background in both regular technology and virtual worlds. In part that was because I was focussing on one major contract, when that dried up suddenly there was no where to go. It is starting from zero again to build up and sell who I am and what I do.
My other startup work has always been ticking along under the covers, as we try and work the system to find the right person with the right vision to fund what we have in mind. It is a big a glorious project, but it all takes time. Lots of no, yes but and even a few lets do it, followed by oh hang can’t now other stuff has come up.
On the summer holiday, I had a good long think about whether to give this all up and try and find a regular position back in corporate life, I was hit with a flash of inspiration for the science fiction concept. It was so obvious that I just had to give it a go. That is not to say I would not accept a well paid job with slightly more structure to help pay my way. However, the books flowed out of me. It was an incredibly exciting end to the year. Learning how to write and structure Reconfigure, how to package and build the ebook and the print version. How to release and then try and promote it. I have learned so much doing it that helps me personally, helps my business and also will help in any consulting work I do in the future. I realised too that the products of both Reconfigure and Cont3xt are like a CV for me. They represent a state of the virtual world, virtual reality, augmented reality and Internet of Things industry, combined with the coding and use of game tech that comes directly from my experiences, extrapolated for the purpose of story telling.
Write what you know, and that appears to be the future, in this case the near future.
This year I have also been continuing my journey in Choi Kwang Do. This time with a black suit on as a head instructor. It has led me to give talks to schools on science and why it is important, with a backdrop of Choi Kwang Do as a hook for them. I am constantly trying to evolve as a teacher and a student. Once again the reflective nature of the art was woven into the second book Cont3xt. I did not brand any of the martial arts action in the book as Choi Kwang Do as that may mis-represent the art and I don’t want to do that, but it did influence the start of the story with its more reflective elements, later on a degree of poetic licence kicked in, but the feelings of performing the moves is very real.
I have continued my pursuit of the unusual throughout the year. The books as a product provide, rather like the Feeding Edge logo has in the past, a vehicle to explore ideas.
I still really like my Forza 6 book branded Lambo, demonstrating the concept of digital in world product placement.

If you have read the books, and if not why not? they are only 99p, you will know that Roisin like Marmite. Why not ? I like Marmite, again write what you know. It became a vehicle and an ongoing thread in the stories, and even a bit of a calling card. It is a real world brand, so that can be tricky, but I think I use it in a positive way, as well as showing that not everyone is a fan. So the it is just another real world hook to make the science fiction elements believable. So I was really pleased when i saw that Marmite had a print your own label customisation. It is print on demand Marmite, just as my books are print on demand. It uses the web and the internet to accept the order and the then there is physical delivery. I know its a bit meta but thats the same pattern Roisin uses, just the physical movement of things is a little more quirky 🙂

I have another two jars on the way. One for Reconfigure and one for Roisin herself.
I am sure she will change her own twitter icon from the regular jar to one of these later as @axelweight Yes she does have a Twitter account, she had to otherwise she would not have been able to accidentally Tweet “ls -l” and get introduced to the World changing device @RayKonfigure would she?
All this interweaving of tech and experience, in this case related to the books, is what I do and have always done. I hope my ideas are inspirational to some, and one day obvious to others. I will keep trying to do the right thing, be positive and share as much as possible.
I am available to talk through any opportunities you have, anytime. epredator at feedingedge.co.uk or @epredator
Finally, last but not least, I have to say a huge thank you to my wife Jan @elemming She has the pressure of the corporate role, one that she enjoys but still it is the pressure. She is the major breadwinner. You can imagine how many 99p books you have to sell make any money to pay anything. She puts up with the downs whilst we at for the ups. Those ups will re-emerge, this year has shown that too me. No matter how bleak it looks, something happens to offer hope. I have some new projects in the pipeline, mostly speculative, but with all these crazy ideas buzzing around something will pop one day.
As we say in Choi Kwang Do – Pil Seung! which means certain victory. Happy lucky 7th birthday Feeding Edge 🙂

Using the Real World – IoT, WebGL, MQTT, Marmite, Unity3d and CKD

All the technology and projects I have worked on in my career take what we currently have at the moment and create or push something further. Development projects of any kind will enhance or replace existing systems or create brand new ones. A regular systems update will tweak and fix older code and operations and make them fresher and new. This happens even in legacy systems. In both studying and living some of the history of our current wave of technology, powered by the presence of the Internet, I find it interesting to reflect of certain technology trajectories. Not least to try and find a way to help and grow this industries, and with a bit of luck actually get paid to do that. I find that things finding out about other things is fascinating. With Predlet 2.0 birthday party we took them all Karting. There was a spare seat going so I joined in. The Karts are all instrumented enough that the lap times are automatically grabbed as you pass the line. Just that one piece of data for each Kart is then formulated and aggregated. Not just with your group, but with the “ProSkill” ongoing tracking of your performance. The track knows who I am now I have registered. So if I turn up and rice again it will show me more metrics and information about my performance, just from that single tag crossing the end of lap sensor. Yes that IoT in action, and we have had that for a while.
Great fun karting. Yay for being faster than 9 year olds :)
The area of Web services is an interesting one to look at. Back in 1997, whilst working on very early website for a car manufacturer, we had a process to get to some data about skiing conditions. It required a regular CRON job to be scheduled and perform a secure FTP to grab the current text file containing all the ski resorts snowfall, so that we could parse it and push it into a form that could be viewed on the Web. i.e. it had a nice set of graphics around it. That is nearly 20 years ago, and it was a pioneering application. It was not really a service or an API to talk to. It used the available automation we had, but it started as a manual process. Pulling the file and running a few scripts to try and parse the comma delimited data. The data, of course, came from both human observation and sensors. It was collated into one place for us to use. It was a real World set of measurements, pulled together and then adjusted and presented in a different form over the Internet via the Web. I think we can legitimately call that an Internet of Things (IoT) application?
We had a lot of fancy and interesting projects then, well before their time, but that are templates for what we do today. Hence I am heavily influenced by those, and having absorbed what may seem new today, a few years ago, I like to look to the next steps.
Another element of technology that features in my work is the ways we write code and deploy it. In particular the richer, dynamic game style environments that I build for training people in. I use Unity3d mostly. It has stood the test of time and moved on with the underlying technology. In the development environment I can place 3D objects and interact with them, sometimes stand alone, sometimes as networked objects. I tend to write in C# rather than Javascript, but it can cope with both. Any object can have code associated with it. It understands the virtual environment, where something is, what it is made of etc. A common piece of code I use picks one of the objects in the view and then using the mouse, the virtual camera view can orbit that object. It is an interesting feeling still to be able to spin around something that initial looks flat and 2D. It is like a drones eye view. Hovering or passing over objects.
Increasingly I have had to get the Unity applications to talk to the rest of the Web. They need to integrate with existing services, or with databases and API’s that I create. User logons, question data sets, training logs etc. In many ways it is the same as back in 1997. The pattern is the same, yet we have a lot more technology to help us as programmers. We have self defining data sets now. XML used to be the one everyone raved about. Basically web like take around data to start and stop a particular data element. It was always a little to heavy on payload though. When I interacted with the XML dat from the tennis ball locations for Wimbledon the XML was too big for Second Life to cope with at the time. The data had to be mashed down a little, removing the long descriptions of each field. Now we have JSON a much tighter description of data. It is all pretty much the same of course. An implied comma delimited file, such as the ski resort weather worked really well, if the export didn’t corrupt it. XML version would be able to be tightly controlled and parsed in a more formal language style way, JSON is between the two. In JSON the data is just name:value, as opposed to XML value. It is the sort of data format that I used to end up creating anyway, before we had the formality off this as a standard.
Unity3d copes well with JSON natively now. It used to need a few extra bits of code, but as I found out recently it is very easy to parse a web based API using code and extra those pieces of information and adjust the contents of the 3d Environment accordingly. By easy, I mean easy if you are a techie. I am sure I could help most people get to the point of understanding how to do this. I appreciate too that having done this sort of thing for years there is a different definition of easy.
It is this grounding in real World pulling info data and manipulating it, from the Internet and serving it to the Web that seems to be a constant pattern. It is the pattern of IoT and of Big Data.
As part of the ongoing promotion of the science fiction books I have written I created a version of the view Roisin has of the World in the first novel Reconfigure. In that she discovers and API that can transcribed and described the World around her.
This video shows a simulation of the FMM v1.0 (Roisin’s application) working as it would for her. A live WebGL version that just lets you move the camera around to get a feel for it is here.

WebGL is a new target that Unity3d can publish too. Unity used to be really good because it had a web plugin that let us deploy applications, rich 3d ones, to any web browser not just build for PC, mac and tablets. Every application I have done over the past 7 years has generally had the web plugin version at its core to make life easier for the users. Plugins are dying and no longer supported on many browsers. Instead the browser has functions to draw things, move things about on screen etc. So Unity3d now generates the same thing as the plugin, which was common code, but creates a mini version for each application that is published. It is still very early days for WebGl, but it is interesting to be using it for this purpose as a test and for some other API interactions with sensors across the Web.
In the story, the interaction Roisin starts as a basic command line ( but over Twitter DM), almost like the skiing FTP of 1997. She interrogates the API and figures out the syntax, which she then builds a user interface for. Using Unity3d of course. The API only provides names and positions of objects, hence the cube view of the World. Roisin is able to move virtual objects and the API then, using some Quantum theory, is able to move the real World objects. In the follow up, this basic interface gets massively enhanced, with more IoT style ways of interacting with the data, such as with MQTT for messaging instead of Twitter DM’s as in the first book. All real World stuff, except the moving things around. All evolved through long experience in the industry to explain it in relatively simple terms and then let the adventure fly.
I hope you can see the lineage of the technology in the books. I think the story and the twists and turns are the key though. The base tech makes it real enough to start to accept the storyline on top. When I wrote the tech parts, and built the storyboard they were the easy bits. How to weave some intrigue danger and peril in was something else. From what I have been told, and what I feel, this has worked. I would love to know what more people think about it though. It may work as a teaching aid for how the internet works, what IoT is etc for any age group, from schools to boardroom? The history and the feelings of awe and anger at the technology are something we all feel at some point with some element of out lives too.
Whilst I am on real World though. One of the biggest constants in Roisin’s life is the like it or love it taste of Marmite. It has become, through the course of the stories, almost a muse like character. When writing you have to be careful with real life brands. I believe I have used the ones I have in these books as proper grounding with the real World. I try to be positive about everyone else products, brands and efforts.
In Cont3xt I also added in some martial arts, from my own personal experience again, but adjusted a little her and there. The initial use of it in Cont3xt is not what you might think when you hear martial art. I am a practitioner of Choi Kwang Do, though I do not specially call any of the arts used in the book by that name as there are times it is used aggressively, not purely for defence. The element of self improvement is in there, but with a twist.
Without the background in technology over the years and the seeing it evolve and without my own personal gradual journey in Choi Kwang Do, I would not have had the base material to draw upon, to evolve the story on top of.
I hope you get a chance to read them, it’s just a quick download. Please let me know what you think, if you have not already. Thank you 🙂

It’s alive – Cont3xt – The follow up to Reconfigure

On Friday I pressed the publish button on Cont3xt. It whisked its way onto Amazon and the KDP select processes. The text box suggested it might be 72 hours before it was life, in reality it was only about 2 hours, followed by a few hours of links getting sorted across the stores. I was really planning to release it today, but, well, it’s there and live.
I did of course have to mention it in a few tweets, but I am not intending to go overboard. I recorded a new promo video, and played around with some of the card features on YouTube now to provide links. I am just pushing a directors cut version. The version here is a 3 minute promo. The other version is 10 minutes explaining the current state of VR and AR activity in the real industry.


As you can see I am continuing the 0.99 price point. I hope that encourages a few more readers to take a punt and then get immersed in Roisin’s world.
Cont3xt is full of VR, AR and her new Blended Reality kit. It has some new locations and even some martial arts fight scenes. Peril, excitement and adventure, with a load of real World and future technology. Whats not to like?
I hope you give it a download and get to enjoy it as much as everyone else who has read it seems to.
This next stage in the journey has been incredibly interesting and I will share some of that later. For now I just cast the book out there to see whether people will be interested now there is the start of a series 🙂

Forza 6 – 10 years in the making

Today Forza 6 arrived on the Xbox One. I have been a long time fan of Forza. It is now in its 10th year. A decade of what, at the time it came out, was considered to be a poor mans Gran Turismo. It has, in my opinion, surpassed all expectations and been a fantastic franchise. The driving feel and the exhilaration is always spot on. I have also been a big fan of their decal customisation. It was little annoying moving to the xbox one and not having my various logos I had created for forza 5 a few year ago. I still carried on and re-created most of my ‘art’ work on the cars in 5. I had a nice cool stuff collective TV logo back on the 360 and forza 4. However instead I created A Choi Kwang Do logo.
I was very pleased, once I got back to the main menu on Forza 6 to see the custom decals and the layouts for specific cars were available to import from Forza 5 now.
I did my first races in a very old impreza using one of the community designs
Forza 6
Now though I am back in a 2005 Impreza WRX complete with some feeding edge words and a logo on the back long with a bright CKD logo. So thankyou Turn 10 🙂 It now means my drivatar will be appearing random races advertising CKD across the world. Also any network race I am in I can show off the logo for my martial art of choice and also advertise feeding egde at the same time. It is an odd concept that there is still a lot of mileage in (Excuse the pun)
Forza 6 CKD scooby
It was also quite amusing to hear James May and Richard Hammond’s voices, albeit labelled at “Automative Journalist” as opposed to Top Gear presenters. I guess all the voice work was done before the demise of Top Gear as it previously existed.
**Update here is some video of one of the cars in action. It looks better in the flesh as this has been Xbox DVR captured, sent onedrive then uploaded to youtube 🙂

***Update
A longer video using the Forza vista, some driving and a photo of a newer scooby, with a black spoiler to represent a belt and orange wing mirrors to represent a belt tag 🙂

**Update 21/9 I noticed during night races another level of detail that impressed me. I have not noticed headlights behave quite so headlighty before. These my car had different bulbs and cast a different light to the other car on the track with me.
Forza6 headlights
I am going to reward myself with a massive driving session this weekend after I complete writing this #reonfigure novel first draft. Near there, the chequered flag is waving and I can see the finish line.
**Update I just finished the novel !

Emotiv Insight – Be the borg

Many years ago a few of us had early access, or nearly early access, to some interesting brain wave reading equipment from Emotiv. This was back in 2005. I had a unity arrive at the office but then it got locked up in a cupboard until the company lawyers said it was OK to use. It was still there when I left but did make its way out of the cupboard by 2010. It even helped some old colleagues get a bit of TV action
It was not such a problem with my US colleagues who at least got to try using it.
I got to experience and show similar brain controlling toys on the TV with the NeuroSky mindflex gym. This allows the player to try to relax or concentrate to control air fans that blow a small foam ball around a course.
So in 2013 when Emotiv announced a kickstarter for the new headsets, in this case the insight I signed right up.
We (in one of our many virtual world jam sessions) had talked about interesting uses of the device to detect user emotions in virtual worlds. One such use was if your avatar and how you chose to dress or decorate yourself caused discomfort or shock to another person (wearing a headset), their own display of you could be tailored to make them happy. It’s a modern take on the emperors new clothes, but one that can work. People see what they need to see. It could have worked at Wimbledon this year when Lewis Hamilton turned up to the royal box without a jacket and tie. In a virtual environment that “shock” would mean any viewers of his avatar would indeed see a jacket and tie.
It has taken 2 years but the Emotiv Insight headset has finally arrived. As with all early adopter kit though there are some hiccups. Michael Rowe, one of my fellow conspirators from back in the virtual world hey day, has blogged about his unit arriving
Well here is my shiny boxed up version complete with t-shirt and badge 🙂
Emotiv insight has arrived
The unit itself feels very slick and modern. Several contact sensors spread out over your scalp and an important reference on the bone behind the ear (avoid your glasses) needs to be in place.
Though you do look a bit odd wearing it 🙂 But we have to suffer for the tech art.
Emotiv headset
I charged the unity up via the USB cable waited for the light to go green. Unplugged the device and hit the on switch (near the green light). Here I then thought it was broken. It is something very simple but I assumed, never assume, that the same light near the switch would be the power light. That was not the case. The “on” light is a small blue/white LED above the logo on the side. It was right under where I was holding the unit. Silly me.
Emotiv insight power light
I then set about figuring out what could be done, if it worked (once I saw the power light).
This got much trickier. With a lot of Kickstarters they all have their own way of communicating. When you have not seen something appear for 2 years you tend not to be reading it everyday, following every link and nuance.
So the unit connected with Bluetooth, but not any bluetooth, it is the new Bluetooth (BTLE). This is some low power upgrade to bluetooth that many older devices do not support. I checked my Macbook Pro and it seemed to have the right stack. (How on earth did NASA manage to get the probe to Pluto over 9 years without the comms tech all breaking !)
I logged into the Emotiv store and saw a control panel application. I tried to download it, but having selected Mac it bounced me to my user profile saying I needed to be logged on. It is worrying that the simplest of web applications is not working when you have this brain reading device strapped to your head which is extremely complex! It seems the windows one would download, but that was no good.
I found some SDK code via another link but a lot of that seemed to be emulation. It also turns out that the iPhone 8 updates mashed up the Bluetooth LTE versions of any apps they had so it doesn’t work on those now. Still some android apps seem to be operational.
I left it a few days, slightly disappointed but figured it would get sorted.
Then today I found a comment on joining the google plus group (another flashback to the past) and a helpdesk post saying go to https://cpanel.emotivinsight.com/BTLE/
As soon as I did that, it downloaded a plugin, and then I saw the bluetooth pair with the device with no fuss. A setup screen flickerd into life and it showed sensors were firing on the unit.
The webpage looked like it should then link somewhere but it turns out there is a menu option hidden in the top left hand corner, with a submenu “detections”. That let me get to a few web based applications that atlas responded. I did not have much luck training and using it yet as often the apps would lockup, throw a warning message and the bluetooth would drop. I did however get a trace, my brain is in there and working. I was starting to think it was not!
Emotiv Insight Brain trace
So I now have a working brain interface, I am Borg, it’s 2015. Time to dig up those ideas from 10 years ago!
I am very interested in what happens when I mix this with the headsets like Oculus Rift. Though it is a pity that Emotiv seem to want to charge loyal backers $70 for an Emotiv unity plugin, that apparently doesn’t work in Unity 5.0 yet ? I think they may need some software engineering and architecture help. Call me, I am available at the moment!
I am alos interested, give how light the unit is, to trace what happens in Choi Kwang Do training and if getting and aiming for a particular mind set trace, i.e. we always try and relax to generate more speed and power from things that instinct tells you to tense up for. Of course that will have to wait a few weeks for my hip to recover. The physical world is a dangerous place and I sprained my left hip tripping over the fence around the predpets. So it’s been a good time to ponder interesting things to do whilst not sitting too long at this keyboard.
As ever, I am open for business. If you need an understand what is going on out here in the world of new technology and where it fits, that what feeding edge ltd does, takes a bit out of technology so you don’t have to.

Internet Of Things – Choi Kwang Do – Fitbit

This may be a bit late to one of the party but @elemming and I have got ourselves Fitbit Flex HR wearables. This little devices track all sorts of walking movement, sleep patterns and most importantly heart rate. The idea is you wear them all the time and aim to do 10,000 steps a day. I was more interested in the heart rate monitor though and what it meant to my Choi Kwang Do training. Whilst this may stray into exercise bore territory I though it worth showing our martial art in internet of things (IOT) terms with some nice graphs.
It is easy when devices and numbers are in place to over fixate on the numbers, but it makes sense to use instrumentation as a check and balance for your own personal experience.
The last few weeks I have ramped up my training at home, having practiced this art for 3 1/2 years I am still very much learning, but I do have a body of experience to draw upon and some degree of consistent feeling to how particular techniques are going to how much extra I can put into a pattern or speed drill. I have used heart rate monitors before. I used a chest strap one about 18 years ago when I had a little burst of getting fit. (That’s part of the article in may portfolio piece virtual athletes – Sports Technology and games). It was where I came to understand it the different heart rate zones based on age.
I had considered other sports wearables, the Apple Watch was a little to expensive, and other people we knew had fitbits so it added to the game side of things with leaderboard and comparing data.
Yesterday was the first half of a day with it, I had already done 1 hour of Choi in the morning so missed that session. Just before our full class at Basingstoke I did a 17 minute warmup and PACE drill at home.
This involved around 5-6 minutes of stretch. Then 2 minutes of moderate pace punching and kicking on BOB, 2 minutes rest, 1 minute faster harder pace kicking only, 1 minute rest and then 30 seconds flat out with everything. I then warmed down a little with my current combination.
Home Choi Kwang Do Session” alt=”” />
The trace of the heart rate certainly fits the level of work and where I felt I was with my heart rate. PACE drills (Progressive Accelerated Cardio Exertion) is a high intensity short burst training method gradually extending and layering your range. We train for speed and power in short bursts as part CKD rather than long repetitive exercise.
The class session ended up as a very intense one too. We have a number of soon to be black belt students in their run up to a grading. So for the lesson I joined them to do our entire set of patterns. This is around 8-10 minutes of going through each coloured belt curriculum pattern. The pattern is a defined set of movements that build techniques up and up. We can all do this at a good steady pace to maintain the form and technique. After that we had a specific blackbelt recap and evaluation of our current belt. That involved current hand techniques, current kicks, combination and pattern. This then ended with a very high intensity PACE version of the speed drills. This are what they say, fast defined sets of moves. We each had a slightly different set but performed them at the same time. We did inaccessibly fast and multiple sets with a final full on blast at the end of one set flat out (when already feeling flat out). The class then went on with both shield drills and focus mits.
Intense CKD class session
As you can see the initial ramp up is the start of the patterns with almost no heart rate increase, then as it progresses the heart rate starts to climb. The trough after 15 minutes is the rest period before the black belt sets. The plateau at 125 from just before 45 minutes is when the speed is and power are still the same but the body seems to accept this is going to happen. This is when techniques flow the best. It is also when the effort is in holding the equipment for others and encouraging them. It shows the benefit of an intense PACE session soothing into learning mode and technique efficiency.
My resting heart rate is showing at 64bpm after the exercise and sleep which is not too bad.
By contrast, and in not was worse is the walk to school and back
School Walk
It shows how a nice steady activity, not over doing gets the heart rate in a comfortable fat but position.
So armed with this information, and now with a reference point I can use the device to reflect on various elements of training and hopefully make my techniques better and more effective.
With some improvements in the sensors that detect out body movement we should be abel to make some great strides in how specific body movements are delivered with great effectiveness but being mindful of the more pure nature of a martial art in just doing it and being in the moment.
Pil Seung!

Martial Arts, Science and Tech for Secondary School

Having returned for a great snowboarding and skiing holiday with the family,

I dived straight back into presenting and explaining science and tech. This was a slightly different request through STEMnet though. A local secondary school teacher asked if I could come and take about biomechanics and martial arts to try and help her students see why science is still an important subject to stick with.

I ran two sessions but built a new presentation specifically for this audience and reason.
Usually I am explaining tech, the future, metaverses etc but putting things like Choi Kwang Do and learning guitar into the mix to make things a little more human.
This time though the hook was martial arts. As Martial arts are not generally taught in school (though the should ideally be part of the curriculum) they are something that has a degree of intrigue to people. Choi Kwang Do in particular is based around a lot of ground up application of scientific principles. It is also not a combat sport, but a defence art aimed at improving your overall mental and physical well being. i.e. it’s idea; for this sort of talk.
I am not going to post the presentation as it featured a lot of video, very few words on slides and a lot of talking and demonstration.

The format though was….
1. Intro to who I am, what I do. I was wearing my Dobok and belt as part of the impact, but indicating my background and work as a techie. I also showed some custard pie throwing from The Cool Stuff Collective. My aim was to show that breadth of knowledge and experience is important and the ability to change is key.
2. I gave a potted history of CKD and showed some of the variety of people performing CKD. I showed predlet 1.0 in a video at a showcase event. It had all ages, sizes and abilities of people in it. The aim to remove the macho, teenage boys only, type of image and engage the entire class. I explained the classes that Master Scrimshaw runs in basingstoke too. I also had the values and pledge on screen to mention.
3. Next up was to talk about Psychology. In part this was about mental states. Dealing with the transition from relaxed, to wary to fight or flight. How the fight or flight state causes massive physical and chemical changes. How being aware of those changes, finding ways to avoid or positively use those is a fundamental part of any martial art. How being in the red and stressed when you don’t need to be will make you ill etc.

4. Physics was next. I pointed out that in a martial art Force = Mass x Acceleration is key. Learning ways to project as much of your mass as possible, as fast as possible is what the techniques are designed to do. Understanding forces and what they are apply to any sport, golf, football, tennis. However I also broke out into showing how we need to understand forces like gravity and cohesion in game development and animations. Here I was aiming to jump subjects to show that the same science and understanding is needing in something very physical and in something, like games development, that is more sat at a desk. The same science.
Also here I played a little trick. Whilst talking about the forces I suddenly jumped into stance and gave a very loud guttural kihap (Martial art shout). This made pretty much everyone jump. A fairly drastic pace change but the aim was to then remind everyone of the conversation about fight of flight earlier on. I pointed out that for me as the shouter, I had gained control, I had positive vibes and chemicals flowing and I was ready. For the class they were for a fraction of a second confused. Their body will have gone straight to code red, in fact jumping was part of fight or flight but almost taking them into tonic immobility, frozen in fear. A simple loud noise, out of context had caused metabolic changes in all of them. i.e. make the science personal and relevant.
Those that already did martial arts, there were a few in each class, were less bothered, seemed more relaxed as they were subconsciously dealing with the threat assessment.
5. I continued to talk about physics and relate that to biomechanics and anatomy. Understanding how to flow movements across your body to generate the acceleration.
6. This led to the neuroscience part. I shared how we learn patterns and sequential movement fits with the way the brain likes to absorb information. Moving from short to long term memory and able to operate when in flow mode works better if the thing you are learning has a completeness to it and a known pattern. In CKD we start and finish in the same place in most moves, we also follow a rounded non stressful sequence. Again I related this to video games and how we learn patterns to deal with situations in games. Discovering the pattern is the joy of play, followed by the mastery of that pattern, getting faster and better scores. Good games need to layer new patterns on old to avoid boredom. Likewise in CKD training we layer onto of mastered moves and patterns with new ones. At its root it all goes back to basics.
I also discussed contralateral movement, working the whole body on both sides for both parts of the brain to create cross hemisphere pathways as the brains neuroplasticity is exercised.
I used the example from Heston Blumenthal of the cinnamon and vanilla ice cream too. Again this was to break the subject, change the mental senses used by the group. With the ice cream made from both vanilla and cinnamon if you sniff cinnamon before tasting the ice cream you will only taste vanilla, like wise with vanilla sniffed first you will only taste cinnamon. This illustrates how you brain and neurochemistry is rigged to look for large changes. You brain filters things out to avoid overloading. The familiar is relegated in favour of the new.
I also discussed how the brain goes into an intense learning mode after a burst of exercise. This seems to be related to reflecting on what a situation was that caused you you be stressed and to escape, how you did it and how you won’t get eaten/killed/caught next time. So we can use our naturally evolved mechanism to increase out learning ability by piggy backing on that fight or flight calm down state.
7.Last up was metabolism. A basic example of the Krebbs cycle, the production and use of ATP as a mini fast access energy source in cells. I did not major on this but used it as a framework to discuss the 15 second bursts of exercise versus the 30 minute aerobic ones. In a defence situation you need to be explosive and able to release the ATP energy, quickly and efficiently and then get away. (Or not be there in the first place which is much better!)
Before heading into the last section I also shared the amazing journey of Sabunim Robbie Close. He went from a very quiet and shy teenage to an assistant instructor then a blackbelt and was then picked to go to Hanseo University in Korea to study a Degree in Choi Kwang Do. This martial art had transformed his outlook, and his life. We had the pleasure of him popping along to Basingstoke for a visit. As the class I was talking to was the age he was when he started it was great to have such a positive role model to share.

8.My final section moved more into the normal territory of discussion using the kinect to see how the body works. I related this again to biomechanics and then also to how we animate game characters and rig bones and joints. I ended up showing Microsoft HoloLens as a mandatory virtual world/metaverse, look here is the future and you can be part of it… the of conversation.
It was a very productive session I think on both occasions, and I hope to run some more. It covers all sorts of science and tech and it may help a few people see the relevance of science in life, or even better see the relevance of a martial art such as Choi Kwang Do.

Learning to teach – CKD and suppressing ego.

This weekend both @elemming and I, along with 140+ fellow Choi Kwang Do practitioners in the UK met for the annual instructors course led by Master Nigel Brophy (6th Dan Black Belt). @elemming has been promoted, along with her fellow cohort of willing students to an assistant instructor at Basingstoke CKD and so now wears a blue dobok. I along with 2 other fellow blackbelts were promoted to Chief Instructors and now wear black and gold.

We are all volunteers, but are willing to forego some of our personal training in order to help and explain Choi Kwang Do to others in the class. I think we all generally find that teaching, having to explain how something works, responding to questions and helping others is as rewarding as just getting on with your own techniques. IT is what makes CKD such a friendly and interesting environment to learn in.
Different people have different approaches to teaching, but everything we do is done in a positive way. This is about a journey, and meandering turns and detours are all part of it. We do have discipline, but it is more of a positive re-enforcement of the good. Who ever is out front guiding, teaching, calling etc is in charge.
One of the hardest things to work on, is not the punching and kicking, but the removal of ego. Watching and listening to Master Brophy I noticed it is possible to be a highly passionate speaker and presenter, an expert in an art form and yet not do it for the applause or the instant buzz of being the ‘star’. To motivate and educate a large body of people they have to believe in you. To do this you have to show your credentials, give them something to say, aha! they know what they are doing. If you truly have the skills, time served, awards etc that is really the easy bit. However it is so easy to tip over the top and let your brain, and mostly your ego, slip into a comfort mode of adoration, or celebrity.
When I do presentations, or evangelise about things, such as the metaverse or STEM in schools I have to switch to a more amplified version of me. If you are put in front of a camera on a TV show, standing on stage with a conference hall full of people, in a classroom full of pupils, you have to enthuse, you have to say look at this and look at me, otherwise it won’t be very interesting. I remember when I used to not want to stand up in front of people and talk. Thinking, well everyone must know what I know, I will just be boring them with the obvious. I also know the feeling of election that people do want to hear what you have to say. When what you are saying is getting a lot of traction and you are very much in demand. It is there you have to check yourself. Unless the thing you sell, enthuse etc is just your own fame and celebrity, in which case just carry on 🙂
So I came to CKD at a time when I had felt a lot of demand for me presenting, but the classes gave me a chance to empty the mental cup and just learn, just be part of a group with no specific responsibilty. It gave me time to practice the off switch.
The problem is, when I get something, when I believe in something and enjoy something so much I have to share it with others. I have forever been told I should be a teacher, but I prefer to not lecture but bring people along with me, help them discover their own path. Luckily, that is precisely what working as an instructor in CKD has enabled me to do. In class I get to both be part of the class, to switch off and focus, I get to teach individually or small groups and I also get to stand up front and do the whole thing. I feel the balance of expectations to please others, or duty to get it right and that little good part of the ego that gets fed by helping others and seeing them progress.
Master Brophy put it well, he mentioned the more you know the more you realise how much you don’t. That is the experts dilemma. He also tempered that with pointing out than when you stand in front of a new student in your blue suit or black suit to teach them something they have never done before, they may well look at you and think you are Bruce Lee.
I think the trick here is to use the fact your are Bruce Lee to them, without deluding yourself you are in fact Bruce Lee.
As with all aspects of CKD other than the physicality of the martial art it is a constant learning experience and evaluation of how we work as humans. The technology, in this case, is our bodies and minds. We explore what we can do with them, for ourselves and others. We deal with scary situations all the time. It may be not being able to remember a pattern, counting out load in Korean in front of others, wondering how to reach a distracted fellow student or holding a shield for a powerful kick. All these prepare the brain to deal with adversity. Teaching and instructing gives the scary part of ego to deal with.
So it seems to me the sooner we get people to experience this sort of thing, in schools and offices, the better. We have a cult of celebrity. This feeds directly to the ego, to the wow I want to be famous feeling. Either wanting to be a premiership footballer or a big brother winner seems to be many a kids ambition. The trappings of fame at a major level can be experienced and felt in a much simpler way, in a safe environment. Stand out in front of class and have everyone follow your every word, then stand back in the class with everyone, whilst the next person takes the stage. That I think teaches a little humility. Having felt that, the next time up front starts, just a little, to become more about the audience.
Whether you believe me or not, that is how I feel about all my evangelising, the TV show was that. I wanted to everyone to know how cool all this tech was, to feel it, to take it and do something with it. I had dabbled with the “fame” thing as one of the corporate poster children for virtual worlds. I had seen the jealousy that created in others. I felt the pressure of the spotlight. I also felt the waning of the “fame”. I dabbled with various ways of exploring my outward persona, trying very publicly to keep aligned with my private persona too, whilst also dealing with these conflicting pressures. It was a a feedback loop though, the more I had done the more I had to do to keep it going. That is not a bad thing though.
I see in Master Brophy a fellow evangelist, though one with much more experience!. Evangelists believe in something, know that its the right thing and the right way forward and want to help, really help, people to see that for themselves. What I hope to do is take my still fledgling knowledge of this martial art and make it as much a part of my willingness to share and enthuse as any of the other cool technologies. The tech I talk about has always been about how people can benefit from it, get some fun or productivity from it. Obviously I have written and blended a few time with the two like here and here. CKD is a scientific based martial art, from the neuroplasticity or the brain, to the biomechanics of the human form to the psychology of teaching and inspiring.
In all that, trying to keep that ego in check too 🙂 (though here is a picture look at me!)

Happy 6th Birthday Feeding Edge Ltd

It is now 6 years ago this month that I started Feeding Edge Ltd! 6, six, VI, Tasset, 3×2 etc etc. However you do the numbers the time has flown by. I like to look back at all the things that would not have happened, or would have been very unlikely if I had not left my then job of 20 years back in 2009. Of course I still do what I did then, with a lot more freedom to operate and explore. Of course it has downsides too. A corporate guaranteed regular high end salary pays for a lot of things, though you have no time to do them. A larger company has people able to cover you, to add to projects and to find other interesting projects. It does of course also have the chance to middle management to act in odd ways and for project scopes to be messed about by sales people.

So as a single person company I have to tread a balance between not over tendering or getting involved in too many projects, but also lay the foundations and seeds for other longer term chances. It is, as the photo about shows of my WWE wrestler a fight, with the chance of some scars 🙂
Right at the moment I am waiting on a multi year development project to kick off. Unity3d and lots of other stuff, it’s more of this. However, external organisations interacting, and being the end of the chain this process has dragged on since before christmas. It is my decision to stay with it, but commercially in the short term it is painful. It is a gamble as I could be spending time waiting for something that doesn’t happen. The previous phase of the project meant I had to technically leave Feeding Edge for a few months as the project did not accommodate “sub contracting”. This ended up just costing me personally as I got enrolled in a pension for a few months and I had left by the time I got any paperwork and never had a chance to reject the pension. Just one of those things.
However the worst feeling was not working for Feeding Edge. I was really, its still my company but officially on the tax books etc I was employed elsewhere on a sort of zero hours contract. I don’t think I will be doing that again. It just means more paperwork and less income 🙂
So while I am waiting I try and not go off selling my services or getting wrapped up in projects. I know full well if I do I will end up not being able to deliver either. There is no such thing as a short term piece of work for me usually as I get embroiled in the whole project very quickly. Quick contract coding no strings attached is not really my style.
So downtime between paying work is spent exploring, learning. I try to do something interesting and learn something everyday.
I am of course available to do other things like TV, Radio, Writing etc. In many ways they make the ideal counter balance for development work. When you are building things you tend to have to block time out to code. I gathered together all my Flush Magazine articles into a portfolio book recently. It was really interesting to see it as an entire body of work

That is only from a few years or writing, so maybe, just maybe I need to write a book after all? A different book to the one I expected to be writing about leaving corporate life 6 years again and telling all, and one that instead focuses on the style of writing I have arrived at with Flush, looking at past patterns and experiences and projecting them forward as a sort of Historic Futurism.
After an interesting twitter discussion with friends old and new today I was still as evangelical as ever about the metaverse and the exiting times ahead as VR and AR headsets demand virtual environments and it starts to become even more normal to expect that sort of interaction. It’s not going away, and neither am I!
Right time to go and get ready to learn and teach my chosen martial art Choi Kwang Do. For over 3 years now this has been a major part of my life and my families life. I have to share this picture as Sabunim Close came to visit Basingstoke CKD this week. He, at 17 was accepted to a Korean university to pursue a degree in Choi Kwang Do. He upped sticks and went there knowing full well it was the right path for him, as there rest of us did 🙂 It was great to see him return on holiday and come and visit us all. Pil Seung (certain victory)

CKD has provided the social contact that working at home and in isolation (despite lots of digital contacts) as well as re-enforcing my own guiding principles of trying to do the right thing and help people.
So, on top of. spending more quality family time, the freedom to operate, the chance to have done 3 series of kids TV, presenting to lots of groups of interesting people, exploring startup life, learning, exploring and building virtual environments I have achieved a life time ambition of a black belt (a life changing experience) and I also get to teach and mentor. Not a bad move was it in 2009 🙂
