Running A Code Club, Not A One Way Educational Street

You'd think that running a Code Club was a one way educational street, with the volunteer enthusing the children about what they could make these things called computers do, but after 5 years I've found the street to be very different with traffic flowing in both directions! You see by day I'm a software developer who once a week goes to a local primary school to run an after school coding club. You'd think that after 20+ years in the IT industry there would be nothing that the children could teach me, but every week I'm learning and being reminded of things!

Today primary school children are taught coding and computational thinking through environments like Scratch, a fantastic, welcoming and friendly place to start that firmly puts fun and creativity front and central. Individual commands are replaced with colourful blocks which can be snapped together to make programs that animate characters or control a robot. For developers who live in Microsoft's Visual Studio world, these definitely aren't fully fledged development environments! With a limited instruction set, few variable types and not the smallest hint of objects you are constantly having to go back to basics. And this is the thing that I am constantly reminded, "Keep it simple". At a time where new frameworks and developer tools are being thrown at us on a daily basis it's all too easy to get swept along with using them. Now I'm not saying that all these technological advances should be thrown away but a happy medium between the two should be striven for. Throwing in a "clever solutions" just for the sake of it while might seem like a good idea, could lead to others wondering how something works. Remember you’re not always the developer who will be doing the next change! If working as part of a team, code produced should not only do what is asked of it but also be easily manageable!

A child's head being full of ideas is the next thing I constantly face. Once they start seeing what they can create, ideas start tripping over each other. I want to create a game, a car driving game, through a maze, with monsters, and can shoot lasers! All this after they managed to make Felix the cat (Scratch's introductory character) bounce around the screen. This is the next skill the children constantly bring out in me, one of listening to someone's requirements. Then after listening, feeding back to them in achievable chunks and letting they know when something is impossible to do. Personally I want the children to leave each week feeling happy with what they have created and if they have some grand plan that they can see progression towards their goal. All of this isn't just applicable to the children's requests, as developers we can face these sort of challenges on a daily basis and if not handled properly can result in others not being happy with what is delivered and more stress on yourself.

Next is the children's level of creativity, it constantly reminds me to keep searching for new ways of doing things and to never accept the status quo. It's all too easy to just do something because it's the way it's always been done. But this doesn't mean it’s the right or best way. The children's creativity is never constrained by a box of what has gone before and neither should ours. Yes we may have been bitten by failures in the past and we bring these experiences to the table but that doesn't necessarily mean the same will happen now! Technologies change, advancements are made, so re-evaluate before casting an idea on the scrap heap.

Finally we have the children's boundless energy and enthusiasm. Sometimes it's all too easy to forget why you got into the IT industry, for me it was the love of coding, problem solving and logical thinking. Sometimes a job can end up being a mundane routine, something you do Monday to Friday, 9 till 5. Then every week the children's energy and enthusiasm remind me that I love to code too. Their attitude to all this coding lark is infectious. They remind me of my younger self, without the pressures of everyday life, where I was coding my own ideas, without deadlines. They remind me that within the confines of an IT job there are still places for everything they hold dear, keeping things simple, listening, realism, creativity, energy & enthusiasm. These kids aren't being forced to attend Code Club, they want to be there, they want to learn, they want to express themselves, they want to have FUN!

This blog post was written off the back of a lightning talk that I gave at a developers conference.

Code Club, Making a Difference

For the last 4 years, once a week, during term time I have run an after school Code Club at a local primary school. If you haven't heard of Code Club before it's a nationwide network of volunteer-led after school coding clubs for children aged 9-11. In the 4 years since it's launch there are now more than 4,500 clubs being run each week across the country reaching over 64,000 children, and all this for free!

Now you may ask why I do this, well it's simple, to make a difference. Children are so open to ideas and to be able to show them what they can do with computers is a fantastic opportunity, it opens their eyes to a whole new world of possibilities. Many children are happy playing computer games but never once think how the games were created, how pressing left on the controller moves their character on the screen. Through Code Club I get to show them how to create simple animations and games and introduce them to coding concepts.

It doesn't just stop at coding though, it's also "Computational Thinking". For example we introduce to the children the idea of breaking big problems down into manageable chunks (decomposition) and developing steps to find a solution to a problem (algorithms). These aren't just applicable to coding either, they can be used across the whole school curriculum and provide a valuable life skill. So even if the children decide that coding isn't for them, they'll still take away something very useful. All of this is done under the overriding umbrella of just having fun, we don't force them to stick to the projects, if they want to add their own creativity, just go for it. The more they enjoy what they are doing the more they are learning.

Recently Code Club uploaded a post to their blog (https://blog.codeclub.org.uk/2016/06/28/the-benefits-of-code-club-for-schools-teachers/) that was written by Matt Warne, the teacher that I had run my club at Malvern Wells Primary School with until summer 2015. He moved onto a new school and I continued running my club with his replacement. The position he took at a large primary school in Worcester was as head of computing and IT. In his blog post he kindly finished off by saying;

“Code Club was a big factor in my journey as a teacher and also the impact of a volunteer Robert Bilsland was enormous. He was a fabulous role model and continues to inspire pupils and teachers to ‘have a go’ in this enormously rewarding subject.”

I find the fact that someone took the time to write such kind words humbling. The "Code Club Effect" is being felt by more than just the children in the club. By teachers helping at a club they are able to gain more confidence in the subject which in turn leads to better inclusion in other subject areas and sharing what they are learning with colleagues. This results in even more children (that don't even attend a Code Club themselves) benefiting indirectly.

Earlier in the year Code Club also named me as one of their "Champions". This recognised my continued support of Code Club, sharing my volunteer experiences with others, supporting activities like science fairs and presenting at meetings. I find the opportunities that I am given to help enthuse children about computing and share my enthusiasm for what Code Club is trying to achieve very rewarding. It is moments like these that mean so much to me as it shows I am truly making a difference.

Why now is a great time for VR and digital planetariums

We are at the beginning of a fantastic period for Virtual Reality, the latest of many waves going back as far as I can remember. With a whole field of VR headsets (Oculus Rift, Microsoft Hololens & Google Cardboard to name but 3) all vying to be the next big thing, focus is switching from the devices themselves to what they are going to be used for. After all without content they are nothing more than items that collect dust on a shelf.

Up to now a lot of developers have been focusing on virtual worlds to explore and play in, but now with advances in technology and falling costs the opportunity to shoot 360° video is now within the reach of more people. Everything from multi-camera solutions (360Heros & Google Jump), through single camera / multi lens devices (Giroptic 360Cam & SpheriCam) to single camera / single lens devices (Kodak SP360 & Eye Mirror 360º). None of these devices are perfect, each having their own pro and cons, but all having the ability to shoot 360° video.

Now some of these devices, in my option, have reached a quality / cost / complexity tipping point. Before this if you wanted reasonable quality it came at a cost and required a certain amount of technological know how. But now there are devices that are  affordable, produce reasonable quality content and don't require an in-depth knowledge on the subject. This in turn is resulting in a whole swath of film makers getting access to the format for the first time.

This is where things are getting great for digital planetariums too. You see in most cases the 360° content that is being produced for VR headsets just needs a bit of tweaking to be able to be projected into a dome (something most content creators hadn't even considered as an option). Unfortunately not all content is suitable, especially where the viewer is required to look down! Most domes only covers a 360° x 90° view (the top half of a sphere) so you can look from straight up to the horizon in all directions, but with a bit of adjustment it is possible to extend what is projected to an amount below the horizon as well.

Over the past couple of years I have been experimenting with re-projecting 360° content from a wide list of genre's (artistic, music, action, scenic) with great success. It has provided a fantastic learning experience as to what works / doesn't work in a dome and how people experience the format. It has shown me that digital planetariums aren't just one trick ponies that only show journeys into space. They can just as easily show an immersive environments as VR headsets, placing the viewer in the middle of an all round view.

Some people may question if its worth bothering with digital planetariums as the number of people who have access to one is lower than VR headset ownership and the domes that are out there are already fully booked showing their own content. Well things have changed, there is now a whole new breed of portable digital planetariums that can sit up to 40 adults (or even more children) where ever there is enough space. You don't even have to own one yourself as there are companies that will bring a dome and show your content for you (here in the UK there is a company called Immersive Theatres).

Finally one of the biggest advantages of domes over VR headsets in my eyes is a social one. If what you are looking for is the ability to be immersed in a virtual environment by yourself then maybe a VR headset is for you, but the experience doesn't always have to be like this. The experience could be one that you share with others.

Another Code Club Year Comes To An End

Another amazing Code Club year complete, my 3rd and I'm still having so much fun. Of course all this is mixed in with feelings of sadness as I said goodbye to some of my children as they move onto secondary school. But as I saw them for the last time I was proud at what Code Club had enabled me to do. I'm sure either with or without the club they would all love using computers (they're a fantastic bunch), but I hope I have been able to open their eyes to a whole new world of possibilities and help fill their heads with ideas of what they could achieve. In the 3 short terms we had gone from coding Scratch, through to soldering Technology Will Save Us's DIY Gamer Kits and finally ending up coding Arudino's.

Everything I threw at them they handled with confidence, enthusiasm and creativity. I was concerned that the soldering was going to be too much, but how wrong I was, the level of concentration during those weeks was off the scale. Every single switch, resister, light dependent resister and buzzer on those kits was 100% soldered by the children. It would have been a lot quicker (and safer) to allow each child to solder a single switch and then do the rest myself, but it was achievement I wanted the children to feel for themselves. For them to be able to hold a piece of technology in their hands and feel proud at what they had put together, after all computers are nothing without hardware.

They also took their knowledge (and creativity) of Scratch and mapped those skills onto Arduino sketches with ease, it really showed that they were learning skills that they could transfer from one area to another.

Earlier in the year we were also lucky enough to be visited by BBC Midlands Today. They were looking for a school that used computers in their lessons and Malvern Wells was able to be that school. The kids loved seeing themselves on TV and I managed to get a small mention for Code Club in too.

The other good news, tinged with a note of sadness was that the teacher I had worked with for the last two years, Matt Warne, had got himself a new Job as the head of computing at the much larger school in Worcester. He said that I had inspired him to push his teaching career further into computing and after becoming a CAS Master Teacher he applied for the position of head of department and got it. I find his words very humbling and kind and wish him all the success that he deserves. I'm sure with our common interest our paths will cross again and I look forward it. Good luck Matt.

So now I'll spend my summer months making sure I'm up to date with all the new Code Club worksheets, reading up as much as I can on the BBC micro:bit (it looks like it could be so much fun, for everyone involved!), thinking about what to start the new Autumn term with and looking forward to meeting new children and a class teacher, all hopefully as eager to find out what this coding thing is all about.

Adventures in Sonic Pi

Well what a fun few weeks this has been getting to this point. I had been aware of Sonic Pi for quite a while, but not having a Mac or easy access to my Raspberry Pi I hadn't been able to play much. This all changed with the release of the PC edition. With easy access to desktop PC's and laptops around the house I could play to my hearts content.

Like everyone else I started by looking at examples and what others had already done, there was so much creativity out there. One of the first things I came across was Robin Newman's blog and his posts about using a limited set of samples of a Grand Piano to create an instrument that could play a much wider range of notes (here). I liked the technical aspect of this but wondered if the concept could be made more accessible.

I set about attempting to create a Ruby class that would provide the same functionality. After plenty of reading up on Ruby (its not a language I usually develop in) and a few coding dead ends, I ended up with a couple of Ruby classes that did the job. Of course just releasing this code would have been no fun at all, people want to hear Sonic Pi playing music. So I set about putting what I had just created to use and coded a version of "The Entertainer".

If you want to jump direct to the code then I've dropped it on a Gist here and the required Grand Piano and Clarinet samples taken from the fantastic Sonatina Symphony Orchestra resource are in a zip file here (Google Drive has a download link at the top of the page). Once downloaded remember to change the use_sample_pack (line 143) to point at the location you have extracted the samples to.

If you just want to enjoy this rendition of  "The Entertainer" then the mp3 file can be found here (again Google Drive has a download link at the top of the page if required).


So you want a bit more of a breakdown of what I created?

First I created a class that all it does is play a specific note from a given sample (line 5). Each instance of the class contains the name of the sample to be played and amp, attack, rate, release and sustain settings. When the play method is called a duration is passed and is combined with the attack, release and sustain settings. These three settings are more reflecting how much of the duration should be spent doing each and in total should add up to 1. If they don't this will shorten or lengthen the requested duration. This feature can be turned to our advantage by allowing the note to carry on longer than the requested duration. This is done by the three settings totalling up to a number greater than 1. This would allowing, for example, piano strings to ring for slightly longer.

Next I created a class that contained all the samples for an instrument (line 55). Each of the 128 midi notes is mapped to their nearest sample and appropriate playback rate calculated. Every time a new sample is added it first inserts itself at the correct position before making sure that neighbouring notes use the nearest sample. For each of the notes an instance of the note playing class is created and held in an array.

Now how are these two classes put to use. Well everything is done through the second, instrument bank class. First a new instance of the class is created (line 146) passing in a reference to Sonic Pi itself. Next all the samples are loaded (line 147 - 153) each defining which base note the sample is for (in either midi number or note symbol) and what sample to use (either as file name in the sample pack folder or by sample symbol). Finally you can amend any required settings (line 154) from the internal defaults provided. At this point your new instrument bank is ready to go. All you have to do to play a note is call the play method passing in a note (again in either midi number of note symbol) and a duration. Also if you want to play a chord just pass in an array of notes.

The Entertainer (line 140) is played by creating three arrays of notes and durations (one for clarinet, one for grand piano right hand and one for grand piano left hand). A synchronisation thread is started whose only task is to provide the cues for the threads playing each of the arrays. As these threads receive the cues they count them and play the appropriate note for the required duration.

This is my first Sonic Pi project and I'm not even sure I've finished it yet. But as I thought that it was at a good point I thought it was worth sharing. It would be great to hear what you think of it or if you have any questions then please ask away.

Playing in a Dome

I love going out and creating spherical panoramas of the places I visit, its a fantastic way to capture some amazing sights. But after I've created them I'm left with the same ways to visualize them, either using some sort of interactive viewer or a flat static view which sort of removes the immersive 360° experience. Well luckily for me I've recently had the offer of a third way of viewing my work, in a 180° dome.

Last October (2013) I visited an Art event in Birmingham called Illuminate and as the name suggests it was all to do with light. The bit that I was interested in experiencing was the 360° Panoramic Cinema, not a full dome projection but a cylindrical slice all around the walls. It was here I met Toby Norman-Wright and Mario Di Maggio and got discussing my panoramas with them. I was told by Mario about another event he runs in Birmingham on a regular basis called Dome Club and I was invited to bring along some of my content to be shown.

Now we fast forward to today. After some initial experiments with preparing content for a dome, only showing an 180° view meant that you would only experience the world from the horizon up (or maybe slightly tilted forward). I started thinking about showing more, seeing a bit of the floor too. This presented it's own problem. The projection that the dome required was circular fisheye so expanding the view to 250° was not a problem. What was a problem is that the view would be distorted making buildings tower in above you and to correct this I would need to re-map my images. After a bit of scribbling ideas on paper, some Maths and a Python script to do the work my images were re-mapped and ready for projection.

I visited Dome Club being held at the Q Club Complex in Birmingham on Friday 13th June and there I was able to experience my work being projected in a 7 meter dome. I had given Mario both original and re-mapped 250° views so that comparisons could be made to judge if the re-mapping was a success and in my eyes it was. Vertical edges now appeared vertical (again) and the ceiling didn't seem so distant. It's truly a great way to re-live the immersive experience of the original panoramic image.

My static panoramas wasn't the only content that I took to Dome Club, I also took Giroptic's demo panoramic video from Times Square in New York shot on their amazing 360Cam. I converted the original 360° x 180° equirectangular projection to a re-mapped 250° fisheye. This was a bit of an experiment for me as I hadn't worked with panoramic video before and the 360Cam is still only a kickstarter project (over $1.1 million funded project at the time of writing!). The immersive experience was outstanding and from such a small handheld device. It really did show what will be possible for content creation that is then shared with a mass audience. Truly interesting times for spherical panoramic video and an area that I want to carry on experimenting with.

For anyone interested in seeing what a re-mapped 250° fisheye video looks like you can see the Time Square demo video over on my YouTube channel here http://youtu.be/VUZKKxP1DYA.

An MP Came Visiting

Back at the end of March I was lucky enough to be invited by Code Club to attend Parliament and be part of a drop in session for MPs. I was 1 of 5 volunteers who got to talk to MPs about what a great thing Code Club was and what the children were learning from it. Along with the volunteers being invited, the volunteers local MPs were also invited to find out what was being taught in their constituencies, for me this was Harriett Baldwin MP. I had a fantastic meeting with her in Portcullis House where she showed interest in the whole subject area and could see the benefits the children were getting. Before she left she asked if it would be possible to visit my Code Club back in Malvern and meet the children herself. After checking with the school that it was ok a visit was scheduled for Friday 16th May.

On the day of the visit there was much excitement within the club with everyone waiting for our guest to arrive, some having stories to recall about them or another family member meeting Harriett. She arrived with her Senior Parliamentary Assistant Edward Davies and was soon being introduced to everyone. I quickly showed her the progression the children had made during this academic year, showing her examples projects first from scratch, then HTML & CSS before finishing on the Python project that they were working on that week. She was amazed by the creativity shown by the children, all starting on the same project but including their own interpretations by the end. She was also pleased to see girls learning to coding too and was eager to encourage more girls to learn theses skills. She talked to everyone and really engaged with the children finding out what each of them was doing and how they were finding the club.

All too quickly we were at the end of the club. She thanked the children for showing her their club and they thanked her for visiting too. Before Harriett had even arrived she had already got 2 more Malvern schools interested in running a Code Club and she asked me what else was needed. I replied with Code Club providing all the required projects and support for free all the was needed was more me's! Other volunteers with IT backgrounds that are enthusiastic about wanting to teach Computational Thinking and coding to the next generation of children. So to help towards this she said that she would talk to other IT companies on the Malvern Hills Science Park (where she has her constituency office) and also other companies that she came in contact with. In the days after the visit a press release was written to publicize the visit and the benefits the children were get from the club. Hopefully the local press will pick this up and even more people will hear about Code Club.

Keeping the Code Club Projects With You

Having a copy of the Code Club projects to hand can be really useful. Sometime you might want to look something up while another time you might want to show a potential volunteer how great the resources are. Originally I had a copy of all the project PDFs on my Nexus 7 and could access them via a shortcut on my home screen that would take me to the top folder. This method was ok but with all the projects getting refreshed and being hosted on GitHub I thought that there must be a better way.

With the ability to download a zip file containing the projects area of the Code Club website from GitHub (https://github.com/CodeClub/CodeClubUK-Projects) I decided that this was what I wanted loaded on my tablet. After expanding the zip file I place a shortcut to the top webpage page on my home screen using ES File Explorer (as I had done with my previous solution). Again this was ok but  but I wasn't quite happy with the result. While previously I was left with a folder structure to navigate through this time I was given a generic html icon that I thought could look better.

After a bit of investigation I came across an interesting feature that was released with build 31 of the Chrome browser for Android (https://developer.chrome.com/multidevice/android/installtohomescreen). When you view a webpage through Chrome you can choose to place a shortcut on your home page that when clicked takes you directly to that page. Even better than that was you could have the page opened in full screen (like an application) and have a personalised image used for the shortcut icon on your home screen. All this is controlled by three extra lines in the head section of the page your interested in linking to.

So I edited the top index.html file in projects zip file downloaded from GitHub. Just below the existing meta tags in the header section I added the following;

<meta name="mobile-web-app-capable" content="yes">

This would open the page in full screen. For the personalised icon I had to provide an image at two sizes (128x128 pixels and 196x196 pixels). This would allow the best icon to be used dependant on what the screen resolution of the device being used was. Copies of my images can be found at the following links;

ccuk_logo_128x128.png
ccuk_logo_196x196.png

I placed copies of these images in the img folder found along with the index.html file. Next I inserted references to the images in the index.html file. Just below the existing link tags in the header section I added the following;

<link rel="icon" size="128x128" href="./img/ccuk_logo_128x128.png">
<link rel="icon" size="196x196" href="./img/ccuk_logo_196x196.png">

Next I had to open the index.html file in Chrome, not as easy as it sounds. The method I used was to open ES File Explorer, select the file, chose to open as, when presented with a list of what to open it as to choose other and finally when presented with a list of applications to choose Chrome. Now this will open the page like normal, not full screen just yet. Next from the drop down menu I chose to Add to home screen and from the dialogue that appeared I named it UK Projects. After clicking add I got a Code Club logo on my home screen that when clicked launches like application. Unfortunately it is slightly spoilt by a line appearing at the top showing that page is being loaded directly from the internal memory. You can get rid of it but you have to load the pages through a local HTTP daemon and I'm not that bothered by the text.

Code Club, between terms

Well one term finished and a new one not too far off at Malvern Wells Primary school. Looking back it's amazing to think what the children have covered at Code Club since the beginning of the year and how well they picked everything up. Not all the children learn at the same speed, but with a few nudges in the right direction everyone gets there. The Autumn term was all Scratch, and what a fantastic place to start. We covered everything from a cat chasing a mouse to fish chomping and racing across a desert to a simple drawing package. The children took everything in their stride, like giant knowledge sponges.

For the spring term, we changed direction a bit, looking at HTML & CSS. Gone was the wonderful drag and drop interface, replaced with a keyboard and commands to type. Would this put the children off? Would it not be as fun any more? I needn't have worried, they picked everything up at the same break neck speed and were soon coding HTML tags and CSS styles without an issue.

First they created their own "Lost Cat" web page, that definitely weren't identical pages. Each child brought their own creative skills to the task, interpreting it in their own way. For some colours and styles were important, expanding on what they had learnt while others brought their own flare to the text, expanding on their story of the lost cat. A real moment of achievement came when they found out that the pages they had created would be uploaded to the Internet using TeePee.io for the world to see. For such a small task the ability to have a URL they could take home to show their parents what they had created was a real reward for the children.

After this we moved onto hiding Ninjas around a town using positional CSS. This time there was different units of measure to get to grips with and after a bit of trial and error the concepts were grasped. Some of the children repeatedly tweaked their Ninjas positions to make sure that the smallest piece of hand or foot couldn't be seen while others placed all theirs in the same place resulting in a squash of Shinobis behind a skip!

Finally they got to use their creative skills to build their own website on any subject they wanted. Some took a topic areas that they had already covered in class while others embedded YouTube videos that they wanted to share. It really showed what they had learnt in such a short time.

I'm now looking forward to the Summer term and teaching the children Python, but this required a bit more planning. For the first term the school already had Scratch installed and for the second term we used notepad and the Chrome browser, but Python was something different. Luckily the school has a technician on rota and I got my request in for Python to be installed early enough so that by the end of the Spring term we were ready to go. It'll be an exciting time getting the children to put together what they have learnt in the first two terms. From Scratch they will be able to take all the programming concepts, loops, conditions and logic flow and combine that with the art of typing syntax (and making sure its right) that they learnt with HTML & CSS. Maybe even for the final lesson I might let them have play with Python and Minecraft on my Raspberry Pi, but this will be a surprise, so keep it under your hat.

Playing with Google Map Views

If you just want to get straight to the tour, follow the following link:
https://www.google.co.uk/maps/place/Great+Malvern/@52.110278,-2.330287,3a,90y,240.55h,90.68t/data=!3m5!1e1!3m3!1s8VPHNkPUB-QAAAGuqllMng!2e0!3e11!4m2!3m1!1s0x4870f8ee8ec8d3fb:0xad5d1163a51c6fd


After reading about the launch of Google Map Views (http://maps.google.com/views) I thought that I would give it a go and add my own spherical panoramas to Google's Street View eco-system. There seemed to be plenty of people uploading single panoramas but I wanted to give their tour builder a try. Not wanting to start too big I chose Rose Bank Gardens in Malvern as a location to photograph. It's a small park in the centre of Malvern with a little network of paths and few entrance / exit points.

Now here is where I hit my first problem, Rose Bank Gardens wasn't mapped on Google Maps. Without this I would be dropping my panoramas into the middle of no-where. Luckily Google already had this covered with Map Maker (http://www.google.co.uk/mapmaker). It allows anyone to update Google's maps with new or corrected content. Unfortunately updates made to any of these systems aren't instantaneous and each application comes with its own learning curve. The major thing that slows down map updates is the fact that they are peer reviewed. Now in an area where there is lots of activity this might be quite a swift but here in the UK and more importantly the Malvern area it took a while. But after a few revisions I had completed the basic network of paths (I say basic because there are a few that at the time of writing I haven't yet created) and this then allowed me to move onto the next step, Google Map Views.

First I needed to shoot the panoramas. Luckily I had already shot a view by of Walenty Pytel's Buzzards sculpture so that was one down straight away. I picked a bright and sunny Sunday morning to visit Rose Bank Gardens, camera and tripod in hand. As I walked through the park I stopped at key points to shoot panoramas and by the end I had shot 23 new panoramic views. After a bit of processing at home I had 24 jpeg images ready to upload (I had to shrink my original images to meet Google's requirements). Now comes the convoluted bit, first I had to insert some metadata into my jpeg images to get Google to recognise them as panoramas. Luckily Google came to the rescue again providing a web application to do this (http://photo-sphere.appspot.com/).

Next I needed to upload my panoramas to somewhere. Now everything you do with Google is authorised through your Google account and this is no different. I had to upload my 24 panoramas to my Google Plus photo library from where I could finally add them to Google Map Views. Now all this might sound a bit long winded but some of it is being caused by the fact I shoot with my DSLR. Google's preferred route is to use an Android phone which would automatically do a lot of the steps for you.

With all 24 of my panoramas being shown on a map it was a process of placing each panorama in it's correct position, making sure north was pointing north and linking each panorama to each other. Now here is where the next delay came in, to make your panoramas visible to the public they have to be processed by Google. This time it's an automated system that looks at each panoramas to see if it is going to be accepted. Most of mine were accepted first time but a few were rejected due to my copyright notice being outside an acceptable area (not that I could find this area defined anywhere) and one which was rejected for an unknown reason that I had to take up with their support staff. Once they were all accepted the tour was visible for the world to see. To take a virtual wander around Rose Bank Gardens yourself you can follow the following link which will place you at the Belle Vue Terrace entrance:

https://www.google.co.uk/maps/place/Great+Malvern/@52.110278,-2.330287,3a,90y,240.55h,90.68t/data=!3m5!1e1!3m3!1s8VPHNkPUB-QAAAGuqllMng!2e0!3e11!4m2!3m1!1s0x4870f8ee8ec8d3fb:0xad5d1163a51c6fd

So what have I learnt through this process? Well with everything being for free don't expect things to happen at the drop of a hat and expect to have to jump through other peoples hoops not ones created by yourself. As for my tour, it uses a method of navigation that people are becoming more and more familiar with all the time which hopefully means less people being stuck on the first view not knowing what to do next. The only warning I give is that if you navigate from one of my panoramic views to a Street View view then currently there's no way back! Outside my tour I've done my small bit to improve the mapping of Malvern by defining Rose Bank Gardens.

Finally what next? Well I want to complete the Rose Bank Gardens tour but I'm going to wait until a fallen stone wall has been fixed (you can see it from the Wells Road entrance). After that who knows, there are plenty of other places to create tours for in Malvern that the Street View Car can't get to, maybe Priory Park?

10 years of panoramic imaging

Ten years of doing anything nowadays is an achievement and I can hardly believe it myself. I started created spherical panoramic images (that's the kind where you can look all the way round as well as up and down, just like Google Streetview) during the August bank holiday weekend 1999 but it wasn't until the beginning of 2004 that the World Wide Panorama project started. Up to this point there had been other panoramic photography events on the Internet but these were organised in a more ad-hoc style. This project brought a structure detailing 4 time periods each years (the solstices and equinoxes) and a clearly defined theme for each event.

During this time I have submitted 62 panoramas across a wide range of themes. From Bridges to Decade and Culture to Gardens. But the one thing I have tried to stick to is to stay local, to the extent that two thirds of my panoramas have been shot within 12 miles from home (and quite a few not too much over this either). Here in Malvern I am spoilt for choice for locations. There is everything from old and historic to new and modern and the Malvern hills form a fantastic divide between the more populated Worcestershire from rural Herefordshire.

Another thing that the event has provided me with is a fantastic snap shot of my last 10 years, with each panoramic image bringing back memories. Some I shot by myself, others with the family, but I remember them all. The winter solstice events always has a theme of best of the year which has allowed me to show views from further afield like the Eden Project at night, a small red phonebox being used as a gallery and the bomb bay of a Vulcan bomber.

The World Wide Panorama project is something I enjoy doing and I look forward to each theme being announced. Now I'm looking forward to the next event the Summer solstice on the theme of Work.

Code Clubs 2nd Birthday Party

Just where have the 2 years gone. When the party was announced I knew I wanted to be there, but it was no simple hop across London for me. Trying to get there from Worcestershire means leaving early afternoon. Luckily I have relatives in Surrey so that gives me a place to stay overnight that isn't too far from London. So after a quick pit stop I was on a train London bound. An hour and a quarter later I was outside the Seven Dials Club, Earlham Street.

To chat with people I have met before and others I hadn't was great, such a wonderful melting pot of ideas. We all had experiences to share and some fantastic ideas were discussed. I know I chatted with loads of people but names have never been my strong point. It was also good to be reminded what Code Club had achieved in the last 12 months and see what they were planning for the next, it's definitely not going to be a year of standing still. With the new primary computing curriculum this autumn it's definitely going to be a very interesting time ahead.

But the evening wasn't all chat. There was some delicious large chocolate discs that contained popping candy sent over by Code Club Luxembourg, sandwiches, plenty of sweets, cupcakes and a free bar. Being projected on a screen there was a huge multi-ball game of pong written by a volunteer and controlled using a makey makey board and some playdough (I just love these boards, so many possibilities). Thanks go to Twilio who sponsored the event.

By the end of the evening I was darting back across London to get my train to Surrey, cupcake and sweets in hand, happy that I had been able to chat with so many people. A really enjoyable night.

A Visit to Parliament!

All blogs have to start somewhere and mine starts here. Recently I was invited by Code Club to be part of a small group to visit Parliament, an honor in my eyes to be asked. On the 25th March I headed down to London and Portcullis house for a 2 hour drop in session where MPs could come along and find out more about Code Club and what the children are being taught in these after school clubs.

I arrived at my destination with plenty of time and was soon clear of the airport style security and armed police. The setting up of the room was frantic with laptops and flat panel TVs being unpacked and set-up. My job along with the other volunteers who were was to give the MPs a real hands on experience of the Scratch environment and the projects that we teach.

The whole event was being sponsored by Samsung and the shadow minister for employment, a Stephen Timms MP (someone who I wouldn't recognise, but more about that later). The order of things was that each MP would be greeted on arrival by representatives from Samsung and Code Code before being passed over to a volunteer. After we had finished being enthusiastic they would then be asked to nominate a local public venue where a Code Club could be run in their constituency. The reason for this was that Samsung were going to help set-up 5 clubs around the UK (from the suggestions provided) providing hardware and resources.

Well the 2 hours soon passed which during I spoke to at least 5 people at length. Each MP seemed interested in the subject and what we were trying to achieve and all providing me with a good level of questioning.

Out of these 2 MPs stuck in my mind. The first was a male MP who presented me with his business card on arrival. I gave him the full tour of Scratch and what we are doing and even challenged him to an game of desert race (of course I let him win) and he went away seeming happy with what he had learnt. Afterwards a Samsung representative asked me if I minded appearing press releases and I replied that I didn't (its good for my ego). It was only afterwards, when press releases appeared, that I realised that this was Stephen Timms MP!

The other MP was my local MP, Harriett Baldwin. All of the invited volunteers had their local MPs invited so that they could find out what was happening in their constituency. On top of this I had tweeted Harriett personally on the Sunday with a gentle reminder which she swiftly replied to confirming her attendance and the fact she was looking forward to finding out more.

On her arrival we recognised each other and I was soon showing her everything about Scratch, what we were teaching to the children and why what we were doing was so important for the children's futures. She could see the potential benefits and was interested in visiting my club and seeing the children at work herself. She hoped that her visit would help drum up some additional local interest too. After my time with her she moved on and nominated the Malvern Cube as a public venue that could run a Code Club in Malvern. It was real pleasure to meet Harriett.

So now I'm in discussion with Harrietts office arranging dates as to when she could visit. My school is on board too thinking it would be a great thing for the school. With Malvern containing such a hub of technology companies it would be great for more Malvern schools to have their own Code Clubs. This year holds some great possibilities for Malvern and Code Club.
