After Tim Harford Tweeted the link to it, I spent a fair bit of time yesterday wrestling with what XKCD reckon to be
The Hardest Logic Puzzle in the World
Here’s how it runs:
‘A group of people with assorted eye colors live on an island. They are all perfect logicians — if a conclusion can be logically deduced, they will do it instantly. No one knows the color of their eyes. Every night at midnight, a ferry stops at the island. Any islanders who have figured out the color of their own eyes then leave the island, and the rest stay. Everyone can see everyone else at all times and keeps a count of the number of people they see with each eye color (excluding themselves), but they cannot otherwise communicate. Everyone on the island knows all the rules in this paragraph.
On this island there are 100 blue-eyed people, 100 brown-eyed people, and the Guru (she happens to have green eyes). So any given blue-eyed person can see 100 people with brown eyes and 99 people with blue eyes (and one with green), but that does not tell him his own eye color; as far as he knows the totals could be 101 brown and 99 blue. Or 100 brown, 99 blue, and he could have red eyes.
The Guru is allowed to speak once (let’s say at noon), on one day in all their endless years on the island. Standing before the islanders, she says the following:
“I can see someone who has blue eyes.”
Who leaves the island, and on what night?’
Now, it’s possible to Google the answer but I thought it would be interesting the explain how I worked it out.Continue reading
Back in June I had the pleasure of helping out at Interactivos Birmingham. This was a fortnight-long workshop for people to develop projects that used?new technologies such as Raspberry Pi and Arduino to make art. In particular, these were pieces of art that responded to the world and people around them. The workshop was hosted and supported by Midland Arts Centre and run in partnership by Birmingham City University, Sampad, the BBC and Medialab Prado.
Nearly all of the projects that took part were using free and open software, and were also making the code that they wrote openly available for other people to see, contribute to and reuse. There is a set of repositories on Github for anybody who is interested in getting into the technical details of the projects.
What I really enjoyed about the workshop was the energy and enthusiasm that all of the participants brought with them. At the start of the fortnight I sat down with some of the project leads who, quite frankly, scared me with the scale of the projects they were hoping to deliver. While not everybody achieved all?they set out to do, each project achieved?lots in the relatively short time scales they had.
You can read all about the individual projects over at the Interactivos Birmingham website, which has loads of different content courtesy of Tim Wilson and BCU social media students.Continue reading
This Saturday is Open Data Day.
The Day Today BBC ? 2014
Data describe the places where we live, work and play and it helps us to understand the world around us. You could be interested in local transport, health or education, our public services create data about all of them. Data can help you hold politicians to account, or it can tell you where the nearest public loo is.
In Birmingham we are holding an event at Birmingham City University where we are going to set up a West Midlands “Open DataStore In A Day”. The idea is quite simple. Over the day we will set up a website that can hold open datasets and publish what we can find to it.?You don’t have to be a technical whizz to take part. Enthusiasm and curiosity are enough to make it worth your while coming along.
We’ll spend the day finding and collecting the data that people are interested in and we’ll put it all together in one place online, in the West Midlands Open Datastore. Once we’ve done that, it makes it all a lot easier to do something useful with.
If somebody can’t find the data that they are interested in then we will help them to write a Freedom Of Information request to ask for it. When those are answered we will add them to the Open Datastore.
I’m really pleased that Data Unlocked, the co-operative venture that I’ve recently helped to co-found, are providing the website for people to work on during the day, and that we will continue supporting it afterwards. We’ve helped to organise the day along with Open Mercia and RnROrganisation.
In?Emer Coleman’s recent post about the City as a Platform?she says that she has seen quotes of up to ?200,000 for Data Platforms. We think that we can do a lot with some free open source software and the goodwill of people volunteering their time and skills.
We are using?Ckan?to host the West Midlands Open Datastore and are thankful to the Open Knowledge Foundation for providing this free, open source software for us to use.?Thanks also to Birmingham City University, who are providing us with a room in their sparky new offices at Parkside.
This Wednesday Nesta are hosting the Pitch and Celebration Event for the Open Data Institute’s first challenge series, which focused on Crime and Justice. I’ll be going down to see which of the three finalists have won the grand prize of ?40,000 and to hear a little more about the next two challenge areas: Education and Energy & The Environment.
Open Data Institute – Challenge Series – Crime and Justice
I had a really enjoyable time working as Series Lead on the Crime and Justice series and am really thankful for the opportunity to work with both Nesta and the Open Data Institute. I think we did a good job of attracting a range of entries and the shortlisting, although difficult, resulted in the strongest projects going forward to the final.Continue reading

I made a couple of Freedom Of Information requests towards the end of last year, using What Do They Know.
My first request asked?Staffordshire and West Midlands Probation Trust for
any reports you have created or commissioned?measuring the effectiveness of programmes you support to reduce?re-offending
They very helpfully responded by placing a number of reports on their website and sending me the link to the page. There are some useful and intriguing reports on there. The reoffending analysis on the Anawin Project, who support “vulnerable women” ?in Balsall Heath is particularly impressive, showing a statistically significant impact on reducing re-offending rates.
However, my second request for individual organisations’ data behind Arts Council England‘s
Regularly Funded Organisations: key data from the 2011/12?annual submission report
has been refused. This data provides information on the benefits brought through millions of pounds of funding to arts and cultural organisations around the country. It’s money that is derived through taxation and so I was a bit surprised when my request was refused, although?Arts Council England were able to provide me with a list of the organisations that either didn’t complete their return, or sent it in late.
I asked for an internal review and although the reasoning was amended, the original refusal has been upheld.
The West Midlands Open Data Forum is an idea that has been initiated by Digital Birmingham. It has a mission
“To promote the release, re-use and integration of open data to benefit communities, businesses and public services in the West Midlands area.”
I was asked to join its steering group a few months ago and have attended three of its meetings so far. Here we have mostly been discussing the Terms of Reference for the group, commenting upon proposals for a Birmingham Open Data Platform and planning how the current steering group will support the new forum to host quarterly events that “bring together developer, activist, public authority, university, third sector and business communities over open data”

Myself and Mike Cummins have been doing some work looking at the Birmingham School Admissions procedure. Over the past year we’ve developed a tool that helps people find out more about the local authority’s schools, including showing the annual cut off distances.
Currently, these school cut off distances are typically provided by local authorities in paper documents or on the web in text formats such as pdf. This doesn’t make it easy for parents to get an overall view of the preferences they might choose. We hope our school finder tool, which allows you to put in a postcode and shows you the schools around you, is a step in the right direction.
Birmingham wide school cut off areas
With the applications for Birmingham Secondary Schools due in at the end of the month we think that now is the ideal time to make an alpha version of the tool available, which we’ve done today. This is a work in progress and the usual caveats apply. Please don’t use it as the only thing you base your decisions on, if you’re looking for a school place for your child.
There’s a feedback forum on UserEcho that we’ve set up for people to comment on the tool and suggest how we might develop it further.
We’re indebted to Caroline Beavon who worked very hard with us at the start of the project, had many of the good ideas and did a lot of the early data work.
There have been a lot of unpublished datasets appearing on the government’s open data portal over the past couple of months. This is part of the response to Stephan Shakespeare’s review of Public Sector Information.
In his review, Shakespeare recommended that the government identify what he referred to as National Core Reference Data. He defined this as being the high quality core data that the public sector maintains already and said that he would “expect to find the connective tissue of place and location, the administrative building blocks of registered legal entities, the details of land and property ownership” in this collection.
The government’s response has been to rename?National Core Reference Data to the National Information Infrastructure. Rather than deciding which datasets should be part of that infrastructure themselves they have been releasing the details of unpublished datasets held within government on to data.gov.uk.Continue reading
Bookings are open for people to attend the Crime and Justice Series hack weekend, known as the Creation and Innovation Weekend, which is being held at Nesta in London over the 12th-13th October. This is the competition weekend for the Crime and Justice Series part of the Open Data Challenge Series.
We’ve created a number of different tickets. People who want to participate can sign up for Individual Team Member tickets. This is for people who want to tackle one of the challenges set for the Crime and Justice Series, which are:
How can open data projects be constructed that achieve one of the following:
– increase community involvement with the criminal justice system?
– create further evidence for what are effective interventions for rehabilitation?
– address the rise in personal crime?Continue reading
Changes are being made to how people convicted of criminal offences are given help towards their rehabilitation. Some of these changes are going to mean that data, and in particular open government data, have an important role to play. In this post I’m going to outline three of these opportunities, all of which could be addressed by projects that participate in the Open Data Challenge Series?challenge:
How can an open data project create further evidence for what are effective interventions for rehabilitation?
The government’s Transforming Rehabilitation agenda proposes to extend rehabilitation services to a wider number of people. For example, from next year everybody?sentenced to fewer than 12 months in custody will receive supervision and rehabilitation. It also seeks to open up a market in the provision of rehabilitation services.
The voluntary, community, social enterprise and private sectors provide services already but the intention is that they will provide more of them and also that they will be able to decide how they provide these, based on their ability to prove their success.
This means there will be an element of payment by results in the new system and I believe there are opportunities for open data projects here.Continue reading
