In a special guest post Anders Eriksen from the #bord4editorial development and data journalism team at Norwegian news website Bergens Tidende talks about how they manage large data projects.
Do you really know how you ended up with those results after analyzing the data from Public Source?
Well, often we did not. This is what we knew:
We had downloaded some data in Excel format.
We did some magic cleaning of the data in Excel.
We did some manual alterations of wrong or wrongly formatted data.
We sorted, grouped, pivoted, and eureka! We had a story!
Then we got a new and updated batch of the same data. Or the editor wanted to check how we ended up with those numbers, that story.
…And so the problems start to appear.
How could we do the exact same analysis over and over again on different batches of data?
And how could we explain to curious readers and editors exactly how we ended up with those numbers or that graph?
We needed a way to structure our data analysis and make it traceable, reusable and documented. This post will show you how. We will not teach you how to code, but maybe inspire you to learn that in the process. Continue reading →
A few weeks ago I announced that I was launching a new MA in Data Journalism, and promised that I would write more about the thinking behind it. Here, then, are some of the key ideas underpinning the new course — from coding and storytelling to security and relationships with industry — and how they have informed its development.

Si vous envisagez de vous mettre à la programmation, il y a de fortes chances que vous butiez sur une série de termes techniques, un jargon qui peut être particulièrement rébarbatif, notamment dans les tutoriels, dont les auteurs ont tendance à oublier que vous êtes inexpérimentés en programmation.
Les sections qui suivent décrivent et indiquent dix concepts que vous êtes susceptible de – non, que vous allez – rencontrer.Continue reading →
If you’re looking to get into coding chances are you’ll stumble across a raft of jargon which can be off-putting, especially in tutorials which are oblivious to your lack of previous programming experience. Here, then, are 10 concepts you’re likely to come across – and what they mean.
Variables are like boxes which can hold different things at different times. Image by Wolfgang Lonien.
A variable is one of the most basic elements of programming. It is, in a nutshell, a way of referring to something so that you can use it in a line of code. To give some examples:
You might create a variable to store a person’s age and call it ‘age’
You might create a variable to store the user’s name and call it ‘username’
You might create a variable to count how many times something has happened and call it ‘counter’
You might create a variable to store something’s position and call it ‘index’
Variables can be changed, which is their real power. A user’s name will likely be different every time one piece of code runs. An age can be added to at a particular time of year. A counter can increase by one every time something happens. A list of items can have other items added to it, or removed. Continue reading →
Journalists rely on two sources of competitive advantage: being able to work faster than others, and being able to get more information than others. For both of these reasons, I love scraping: it is both a great time-saver, and a great source of stories no one else has. Continue reading →
