Cloud Cipher Capabilities

… or, the lack of it. A recent discussion at a customer made me having a closer look around support for encryption in the context of XaaS cloud service offerings as well as concerning Hadoop. In general, this can be broken down into over-the-wire (cf. SSL/ TLS ) and back-end encryption. While the former is widely used, the latter is rather seldom to find. Different reasons might exits why one wants to encrypt her data, ranging from preserving a competitive advantage to end-user privacy issues. No matter why someone wants to encrypt the data, the question is do systems support ...

Common Tag semantic tagging format released today

The Common Tag format for semantic tagging has been finally released today after almost a year of intense work on it by a group of Web companies active in the semantic technologies area, among them Yahoo. It's been great fun working on this and I'm proud to have been involved: while there have been vocabularies before for representing tags in RDF, this effort is different in at least two respects. First, a significant effort of time has been spent on making sure the specification meets the needs of all partners involved. The support of these companies for the specification will ...

Simplified RDF

I propose that we designate a certain subset of the RDF model as "Simplified RDF" and standardize a method of encoding full RDF in Simplified RDF. The subset I have in mind is exactly the subset used by Facebook's Open Graph Protocol (OGP) , and my proposed encoding technique is relatively straightforward. I've been mulling over this approach for a few months, and I'm fairly confident it will work, but I don't claim to have all the details perfect yet. Comments and discussion are quite welcome, on this posting or on the semantic-web@w3.org mailing list. This discussion, I'm afraid, is ...

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 ...
