The building blocks of data infrastructure – Part 2

This is the second part of a two part post looking at the building blocks of data infrastructure. In part one we looked at definitions of data infrastructure, and the first set of building blocks: identifiers, standards and registers . You should read part one first and then jump back in here. We're using the example of weather data to help us think through the different elements of a data infrastructure. In our fictional system we have a network of weather stations installed around the world. The stations are feeding weather observations into a common database. We've looked at why its ...

The building blocks of data infrastructure – Part 1

Data is a vital form of infrastructure for our societies and our economies . When we think about infrastructure we usually think of physical things like roads and railways. But there are broader definitions of infrastructure that include less tangible things. Like ideas or the internet. It is important to recognise that there is more to "infrastructure" than just roads and railways. Otherwise there is a risk that we, as a society, won't invest the necessary time or effort in building, maintaining and governing that infrastructure. The decisions we make about Infrastructure are important because infrastructure helps to shape our ...

Mon intervention lors de l’inauguration du Retour à la Terre Rive Gauche

En attendant la publication des photos et vidéos sur le site du Retour à la Terre , voici le texte que j’avais préparé pour mon intervention lors de l’inauguration officielle du magasin de la Rive Gauche le 18 janvier. Catherine est inquiète parce qu’elle ne sait pas ce que je veux vous dire ce soir… Elle me connaît pourtant bien puisque cela fait plus de trente ans que nous vivons ensemble ! Nous avons la chance d’avoir étudié dans une grande école (l’École Centrale) où nous nous sommes rencontrés mais avons toujours eu du mal à nous intégrer au monde des ...

Yak shaving

If your brain works the way mine does, you often find yourself doing a variety of related but not necessary tasks along the way to fulfilling a larger goal. For some reason, the history of which I’m not entirely sure, this is called “yak shaving.” Some of my finest work has been done that way, so I’m happy to embrace it, even if I do add hours to the job at hand. This week’s yak shaving has neared epic proportions, but proved eminently satisfying. I’ve been working on collecting together an overview of big data products. It’s early days yet ...

HttpURLConnection’s Dark Secrets

If you’re programming in the Java language and want to talk to a Web server, there are several libraries you can choose from. HttpURLConnection is one popular choice, and for Android programming, the engineering team has now officially suggested that you use it where possible. Since there are irritating orthographical and Web-Architecture issues with the name “HttpURLConnection”, let’s just say HUC. HUC is reasonably well documented, if by “reasonably well” you mean “omits any discussion of the relationship between method calls and underlying HTTP traffic”. Let me fill that in. Who knows, maybe some JavaDocs maintainer somewhere will feel inspired ...
