Mobile broadband from Three


I’ve grown tired of the restrictive filtering at work (a necessary evil of working in a school I guess!). I can easily bypass the filtering using ssh-tunnelling (especially as no-one else at work has a clue how all this works 🙂 ) but the tunnel isn’t very stable and the connection is often slow. Incidentally I was able to use the same technique to bypass the filtering imposed by the government in China.

I saw an offer on the Three website for mobile-broadband for half-price mobile broadband for existing customers. The catch was the 18-month contract but at prices from £5 a month it seemed reasonable. I signed up (using the Quidco referral site which earned me £37.50 cashback in the process) for the 1Gb broadband lite package. I guessed that I would be using close to 1Gb a month using the connection for up to 8hrs a day so I upgraded to the 3Gb package for £7.50 a month instead.

Good points of Three mobile broadband:
Fast, fairly reliable, no problems with streaming data, all Internet apps work with it.

Bad points of Three mobile broadband:
Occasionally the connection drops out and you need to disconnect and reconnect.
Sometimes the latency is high so the connection doesn’t feel responsive.
The latency makes it impossible to play online games like World of Warcraft (to be playable).

My impressions of Beijing School for the Blind

This is the unabridged version of an article I co-wrote for the SSAT Inet newsletter with my headteacher. I know it’s a bit wordy but it was hard to cut down and not lose what I wanted to say.

Martin Sutton on visiting the I-Net conference Sept 2007
Rob and I arrived at the lavishly appointed China World Hotel just before midnight on the Sunday before the I-Net Conference and had our first introduction to the wonderful hospitality that we received throughout the conference week.
The presentations, seminars and workshops were of a high quality and the opportunity to listen to and speak with internationally recognised experts and practitioners was invaluable. The mix of delegates from over a dozen countries proved stimulating and the experience enabled me to look at my own school with a fresh perspective.
The rigour of the conference was balanced with opportunities to tour a part of the Great Wall, Forbidden City, Temple of Heaven and Tiananmen Square. Just as interesting, if less organised was the life on the streets around our hotel; the restaurants, shops and the Silk Market.
Our Chinese hosts were keen to show us the best of their provision. I was quite ignorant of the Chinese system of education before the conference and did not know really what to expect. My impressions were almost entirely favourable. The schools we visited appear to benefit from very healthy investment… Teaching staff are hardworking, talented and committed. The pupils and students were universally polite and welcoming and thoroughly enjoyed their opportunities to show their work and their school demonstrating enormous pride in their system. Language was not a barrier; teachers and pupils alike were eager to speak English with us.
On the morning of the first day we met other delegates and some colleagues from a special education background including Professor Barry Carpenter. With Barry’s help Rob and I were able to fit in a visit for a day to the Beijing School for the Blind. My impression of this school is of a highly organised well managed and well resourced school which supports the education of visually impaired young people and also youngsters with other special educational needs including autism and communication difficulties. We were particularly impressed with the commercial opportunities afforded to pupils by the school’s vocational initiatives for older pupils. Rob and I came away from school feeling impressed with the school’s commitment to CPD and feeling very much that our school would benefit immensely from a link with Beijing School for the Blind.
We decided that Rob and another colleague Margaret Stonier our MFL teacher should visit Beijing in April 2008with ssatrust in order to share awareness of the Chinese education and to further our aim of developing CPD and curriculum links with Beijing School for the Blind.

Rob Butler on returning to Beijing in April 2008
When I arrived at Beijing International Airport I was reminded how quick the rate of change is in China. We passed speedily and efficiently through the new terminal 3 building (including a ride on the monorail) which opened in February of this year. As we were driven to our hotel passing the familiar landmarks on the way into Beijing centre, it felt as though I was on the way to visit an old friend. Our scheduled tour of the Hutongs not far from Tiananmen square serves to remind of how far China has come in a relatively short time. The old narrow streets, lined by traditional dwellings around a courtyard, are in marked contrast to the towers and office blocks that dominate the skyline of Beijing. The friendliness and openness of the Chinese people also becomes apparent when you get the opportunity to share their culture with you.
The first full day in Beijing was to be our visit to Beijing School for the Blind. We did eventually make it to the school – traffic in Beijing has to be seen to be believed and the rain only added to the plight of the city’s drivers. We arrived at the school and were immediately made very welcome and, as is tradition, given Chinese tea. The first thing I noticed was how the school seemed so much more “finished” than last time I visited. Although the school is still in the middle of a major rebuilding project the staff had worked hard to make sure the pupils were settled and it showed.
The school had made efforts to accommodate our requests and we were taken to an infant class learning about pizza, tasting a variety of potential toppings and describing the tastes. What became immediately obvious was the similarity between the pupils of our two schools and the challenges faced by all teachers of children with special needs. The lesson was well staffed with a good pupil to teacher ratio and all pupils were engaged with the lesson. Our next lesson was a group of older pupils who had a range of visual impairments. We observed the teacher working with the pupils for a literature lesson. Pupils using their Braille typewriters and were able to enter text with amazing speed. The Braille text books were very thick but served as a good illustration of the investment the school has made in the support structures of the school. When the lesson had finished we were given the opportunity to interact with the class, who had many interesting questions to ask. Cultural differences became apparent in the questions the pupils asked, which all revolved around school and our pupils’ experiences of school. Perhaps the most fascinating part of the interaction was watching the faces of the pupils as my responses were translated. The questions of the pupils and their focus on education were in stark contrast to the priorities of English pupils. Mention of class visits to my house and some of the lessons resulted in gasps and rapid chattering between pupils. I had taken a selection of English sweets for the pupils to try. Tasting the Pontefract cakes led to some interesting expressions on their faces as did the sherbet lemons. The pupils were genuinely interested in what I had to say and thanked me for both my time and for fetching presents.
I wasn’t sure what to expect for lunch but the management of the school had made a huge effort to share with us some of their culture. We were taken to a private room in a restaurant that served authentic Beijing dishes. As well a selection of local dishes, we drank Chinese tea (to which I am now addicted) and toasted our future collaborations with Chinese wine. To a Westerner, one of the biggest differences between cuisines from the two cultures is bones. Smaller animals like fish and chicken are often cooked on the bone which can take a little getting used to. Beggar’s chicken and Squirrel fish were two of the more memorable dishes, both of which were bursting with flavour. Meal times in China are very social, with plenty of conversation and sharing of dishes – something we have lost over in the West.
Our visit to Beijing also gave us the opportunity to showcase our school and how we work with pupils. The courses we offer and the way we work with pupils were watched carefully but the photographs of the school prompted the staff to ask questions and probe the way we work. By the time we were showing the photographs of the sensory room the questions were in full flow. Staff were keen to learn how the multisensory equipment worked and how it would be used with pupils. The teachers were also keen to learn more about the TEACCH approach used with our special autistic group. The presentation concluded with video clips showing our pupils on a fund raising day for Sport Relief, and doing a science experiment for Healthy Eating Day. The staff were very interested in how we organised these days and were keen to replicate the process in their own school.
Day two at Beijing School for the Blind consisted of a tour of the vocational classes. We saw pupils taking an anatomy lesson (as a part of the massage courses) which was delivered using models and a data projector. The pupils were encouraged to work independently and were all able to identify parts of the heart by end of the lesson. We also saw massage classes where pupils were learning about the shoulder and techniques that could be used. Piano tuning is another course pioneered by the school and we were given the opportunity to see how the class learned their new trade. We were also shown the multiple needs group who were very similar in ability and behaviours to pupils in English specials schools. Lunchtime consisted of different local dishes in another restaurant but the atmosphere was much more relaxed with the staff treating us as friends rather than business colleagues. It was interesting that the staff raised the issue of Tibet and were very keen to make us understand the issues through their eyes. Speaking to the staff honestly and frankly made me realise that despite our difference, we are all the same underneath and have the same hopes and aspirations for our children. Whilst I appreciate that Chinese politics aren’t perfect, Western activists and campaigners who want to change the system would do well to visit China and spend some time talking to the people to find out how they feel about it. After lunch we visited the vocational site where some graduates from massage school are employed to provide massage to the public. An impressive range of techniques is offered and the quality of provision was evidenced by the number of members of the public in there.
The last day of school visits saw us visit another special school (with pupils of similar ability to our own) and a mainstream school – The Center School for the Mental Retarded in HaiDian District. The special school had been through a rebuilding programme and had a state of the art building to house its pupils. Seeing my second new build school made me realise the significance that the Chinese place in Education, in a city where space is scarce the new build schools have plenty of room relative to the high rise accommodation that surrounds them. The school well resourced and used a variety of techniques (such as rice play) that compare well to English special schools. Life skills were taught with facilities many English schools would be envious of, including a four lane road with crossing and traffic lights! As with Beijing School for the Blind, the dedication of the staff was one of lasting impressions I took away from the school.
The mainstream school made an interesting contrast to the two special schools, with much larger classes and a more academic and businesslike approach. The school we visited (Beijing no. 57 High School) hadn’t yet been rebuilt and so space was tighter than at other schools. One of the most striking sights was the number of bicycles in their sheds, which is a far greener alternative to the school run done by English parents in their petrol-guzzling cars. Many of the pupils were sitting mid-term exams so we didn’t get to see lessons, only a brief look at some Art, Music and Applied Science (flight simulator) lessons.
Perhaps the most important thing to take away from our visit is that despite the differences between our cultures, we are much more alike than first appearances would suggest. Only by regular contact and exchanges between our two countries can we unpick these differences and understand each other better.

Beijing School for the Blind


Our primary reason for visiting China was to establish a link with a Chinese School to share good practice and cultural information. Having visited Beijing School for the Blind on a previous visit, we had seen plenty that impressed us and areas that we could work together.

Beijing school for Blind takes in blind and partially-sighted children from their catchment area, having a pupil population of around 200. Beijing School for the Blind also has an impressive vocational programme, training their pupils to do Chinese Massage and piano tuning. The school is also doing some pioneering work providing mobility training for pupils, and providing tuition in a variety of subjects. Some of the pupils have multiple special needs, a common occurrence in UK special schools but less so in Chinese schools.

We were fortunate enough to see a range of classes and lessons, and to meet some of the pupils first hand. One thing that immediately struck us was the dedication and professionalism of the staff who truly are a credit to the school. We were made to feel very welcome by the staff and felt like old friends by the time we left.

I hope that as we work together, we can share some of the good practice that exists in both of our institutions and also put to rest some of the misconceptions that people in the UK have about China and the people that live there.

Hutongs of Beijing

Have spent a fascinating afternoon visiting first the Beijing Bell and Drum towers, then the hutongs of the area.

The Bell and Drum towers were ancient time keeping devices, so that workers could keep time before watches/timepieces were common. More information here.

The hutongs are narrow alleyways between lines of traditional courtyard residences. We toured the streets of these hutongs by pedal rickshaw (pedicab) – and stopped several times to visit the homes of Beijing residents who lived in some of these hutongs. As a preserved area, homes in the hutongs are highly sought after, especially with their historical connection to the Feng-Shui of the Ming dynasty. We saw several occupied hutongs, and were grateful to the Beijing citizens who allowed us into their homes.

Arrival in Beijing

We arrived safe and sound in Beijing after a pleasant journey. We were very privileged to have the use of the BA Club class lounge in Heathrow, and then to receive an upgrade to business class! If only I could always travel like this – a reclining seat that turns into a bed seems like an essential part of a long haul flight!

We arrived at the new Terminal 3 building, which only opened in February this year. Last time I came to Beijing I used the old terminal so using the new, shiny and extremely modern terminal (with monorail from arrivals to baggage claim) came as a surprise. Although I couldn’t take any pictures in the airport, this wikipedia entry shows terminal 3.

The pickup and transport to the airport was without incident and seemed relatively sedate by Beijing standards – perhaps that’s due to the rain. Did I mention it is raining here? Check out the picture from my hotel room window! I’m hoping the rain doesn’t spoil our Hutong tour booked in an hour.

Youtube for a nostalgia trip…

Don’t ask me why but when I was sat at my desktop pc I suddenly wondered if Youtube would have any of the favourite videos from when I was a teenager many years ago. Sure enough I found an amazing collection of Debbie Gibson videos including the one linked below. It also inspired me to find out what she was up to now – which led to her website and her myspace site.Unfortunately Youtube is blocked across my educational institutions across the UK, but it is a massive video archive of popular culture and well worth a look. Youtube isn’t just for silly clips recorded on mobile phones!

Nokia N95


I have to say I’m loving my Nokia N95. I wanted a phone with a decent camera (since most of the photos I take are on my phone). The wifi and gps tagging of photos were also features I liked. I’ve added mobile broadband to (I’m on Three – the add-on is X series silver). I’ve also added a software service called Shozu which can automatically upload my images to the internet. I’ve set it to send to Flickr as a default – so I get an instant backup on the web – which others can see too! Check out my flickr photos here.

The only drawback I’ve found is that I turned on geotagging, and of course it geotags pictures that you upload from MMS. Not a huge drawback though. (And it only tags one out of ten pictures!)

I’m also loving the new google maps – with cell tower location finding and the gps, it is pretty powerful. I’d recommend the N95 to anyone who needs a fancy feature-filled phone (and doesn’t need long battery life)

Hosting from home for free – loads of bandwidth and space

Whilst the price of shared hosting is falling, trusting your website to an unknown company is always a risk. Even some of the largest sellers oversell bandwidth and space, so who do you trust your website to? I decided to host my site on my own server at home – since I pay for a 24/7 internet connection.

When I set up my server, I was new to DNS and hosting, and decided to move my domain to who provide a dynamic DNS service. They offer free accounts with popular names like or you can go for your own top level .com domain.

What they don’t say is that you can use their free account and register your domain name with a cheap provider like godaddy. This saves you around $30 per domain – worth it if you have a lot of domains.

All you do is set up your free account with your dynamic provider (and install the update client which tells their servers if your ip address changes). You register your domain with your preferred provider and set up a cname record which points to your free domain name. This means that any traffic going to your registered address is redirected to your free dynamic dns account.

All you then need to do is set up your web server to recognise the new sites you have added and bingo – you can run dozens of sites from one machine. This is the guide I followed.

There are downsides to hosting your own server. First of all you have to pay for your own internet and electricity which is not an insignificant cost. My cable modem offers 400k/s incoming and 40 k/s outgoing (with peak time traffic shaping) for the equivalent of $50 a month. Electricity in the UK is also rapidly rising in price thanks to the lack of freedom in the European energy market – my Dell server costs the equivalent of $10 – $12 a month. Another downside is technical knowledge. Your server is continually exposed to the internet and you need to make sure you only open ports you need, and that you keep the server patched and up to date.

With energy prices rising so rapidly, I regularly review my decision to host from home. Using an older more energy friendly PC will help keep the costs down but there is no short cut to gaining technical knowledge (although you could run a preconfigured server on a virtual machine!).

Do you host from home? Are you looking for free hosting for a blog? Leave me a comment below.

Edit: 15/09/08 Since I posted this originally my workload has increased and I just didn’t have time to maintain my installations (updating the ubuntu server was easy, updating joomla/wordpress a bit more time consuming).  I decided to move my blog back to blogger and rely on Google Analytics for my visitor information.  (That and I also needed to turn the ‘office room’ back into a guest bedroom and the server was too noisy for someone to get any sleep!).

Find out where your spam comes from….

Ever wondered where spammers get your email address from? This is how you can find out – it only works when you start with a new domain or new googlemail account.

Method 1

If you have a custom domain you registered e.g. you own all the email addresses at that domain. If you set all the emails to forward to your current email address you will get all the email that comes to every address. Then all you need to do is when you sign up for a site, you include the site name in the email address you give for that site. For example if you were shopping on Amazon, you would give your email address as where you swap for your own. When you start getting spam email you can see where they have come from.

Method 2

This is very similar but uses Googlemail (Gmail). Google mail has a set of features only recently documented. Because of the way Google parses the email addresses, you can change your email address in 2 different ways and still receive your email. Googlemail takes no notice of where the dots are before the @ sign so you can change these when you give out your email address – although this is not as useful as the next feature. You can also add a plus sign (+) and extra characters after your username and before the @ sign. This has been confirmed to work with regular googlemail and googlemail for domains. This can be used now in the same way as method 1. When you sign up for a new site, add +sitename before the @ sign. For example if you were shopping at Amazon. You could also do this when you give out your email address to friends. When you start to get spam email – have a look and see who sold you out! I’ve started using this method so it will be interesting to see if the email addresses of my incoming spam change!

Playing Warcraft over an SSH tunnel


Scenario: I want to play World of Warcraft at work or behind a firewall. Most ports are blocked although I am able to get a tunnel out (eg on port 443). Of course you need a PC left on around the clock to connect to (or a router running dd-wrt) – to see my other SSH related articles click ‘Technology talk’ on the menu to the left.

Solution: Use a commercial piece of software called proxifier which routes traffic from any piece of software over your ssh tunnel. (Update: There is a new version of proxifier which can be run from a usb key in addition to the standard version)

Open your ssh tunnel using putty (be sure to make sure you have the dynamic/socks tunnel enabled). Opening a tunnel on port 443 is usually possible. I am usually able to open a tunnel on port 443 from where I work (an educational broadband consortium) but on the few occasions when I can’t open one, I can force one if I know the proxy server name by putting the proxy details in the proxy tab. (This link may tell you if you are behind a proxy server – click on ‘Proxy test’)

In the options for proxifier tell it which port your tunnel is on (proxy settings).

You can set it to route all traffic (apart from exclusions) over the tunnel, or to only route traffic from certain applications over your tunnel. I did the latter.

When I started warcraft up I was able to log on from work over my tunnel. Ping times were usually playable (120ms upwards) but this depended on the quality of the connection between your computer and your server.

And there you have it – World of Warcraft over an ssh tunnel from work! Easy when you know how!! (and much simpler than setting up a VPN!).

Of course you need a piece of hardware permanently powered up at the other end but buying the right router or running a low power Linux box like a Linksys NSLU2 is a brilliant way around this (and can also host networked storage, web pages and even torrents whilst drawing very little power).
