OSGi

December 16, 2008 – OSGi

Description

OSGi is a Java-based component architecture that has gained a lot of traction recently. It is simple, provides dynamic updates of components and supports working with different versions of the same JAR or component. OSGi is used to build complex applications like Eclipse, application servers (GlassFish, IBM Websphere, OpenEJB, Oracle/BEA Weblogic, Jonas, JBoss), application frameworks (Spring, Guice), and more. We will discuss the following topics:

• The basic OSGi architecture (bundles, manifests and services)
• OSGi Implementations (Equinox, Felix, Knopflerfish)
• Concrete Uses of OSGi (Eclipse, …)
• Developing OSGi Bundles (Eclipse PDE, Maven, PAX-tools, …)
• OSGi Examples

Using Redis and BloomFilters to fail fast

Sept. 16 2014

From redis.io: “Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets”.

In this talk I will introduce Redis and go over some common uses. I will then introduce the concept of BloomFilter (a space-efficient probabilistic data structure) and show examples of how combining Redis and BloomFilters opens a very interesting set of uses cases typically requiring expensive RDBMS queries.
