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 ...

Dynamic Semantic Publishing for any Blog (Part 2: Linked ReadWriteWeb)

The previous post described a generic approach to BBC-style "Dynamic Semantic Publishing", where I wondered if it could be applied to basically any weblog. During the last days I spent some time on a test evaluation and demo system using data from the popular ReadWriteWeb tech blog . The application is not public (I don't want to upset the content owners and don't have any spare server anyway), but you can watch a screencast (embedded below). The application I created is a semantic dashboard which generates dynamic entity hubs and allows you to explore RWW data via multiple dimensions. To ...

Want to hire me?

I have been happily working as a self-employed semantic web developer for the last seven years. With steady progress, I dare to say, but the market is still evolving a little bit too slowly for me (well, at least here in Germany) and I can't invest any longer. So I am looking for new challenges and an employer who would like to utilize my web technology experience (semantic or not). I have created a new personal online profile with detailed information about me, my skills, and my work. My dream job would be in the social and/or data web area, ...

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 ...
