Introducing Apache Mahout

Once the exclusive domain of academics and corporations with large research budgets, intelligent applications that learn from data and user input are becoming more common. The need for machine-learning techniques like clustering, collaborative filtering, and categorization has never been greater, be it for finding commonalities among large groups of people or automatically tagging large volumes of Web content. The Apache Mahout project aims to make building intelligent applications easier and faster. Mahout co-founder Grant Ingersoll introduces the basic concepts of machine learning and then demonstrates how to use Mahout to cluster documents, make recommendations, and organize content.

heise Developer - 21.04.2009 - 10:24 - Identity Management: Authentifizierungsdienste mit OpenID

Single-Sign-on (SSO) wartet immer noch auf den Durchbruch im Internet. Wer kennt nicht das komplizierte Hantieren mit der Verwaltung von Benutzernamen und Passwörtern für unterschiedliche Webanwendungen? Folgendes Szenario wäre traumhaft: Man stelle sich vor, man hätte einen Benutzername und ein Passwort und könne sich damit überall in diversen Webanwendungen einloggen. Vielleicht müsste man noch nicht mal ein Passwort besitzen, da die Authentifizierung anders funktioniert – beispielsweise mithilfe von Biometrieverfahren. Was sich attraktiv anhört, bleibt zunächst ein Traum. Was allerdings im Internet mit dem SSO-Protokoll OpenID Realität ist, zeigt dieser Auftaktartikel der Artikelserie "Internet-Identität und Datenaustausch heute – Nutzung und Möglichkeiten von OpenID und OAuth".
