Docker Secure Deployment Guidelines — deployment checklist for securely deploying Docker.
The Devops Identity Crisis (Baron Schwartz) — I saw one framework-retailing bozo saying that devops was the art of ensuring there were no flaws in software. I didn’t know whether to cry or keep firing until the gun clicked.
Apache Giraph — an iterative graph processing system built for high scalability. For example, it is currently used at Facebook to analyze the social graph formed by users and their connections.
Apache Flink — a data processing system and an alternative to Hadoop’s MapReduce component. It comes with its own runtime, rather than building on top of MapReduce. As such, it can work completely independently of the Hadoop ecosystem. However, Flink can also access Hadoop’s distributed file system (HDFS) to read and write data, and Hadoop’s next-generation resource manager (YARN) to provision cluster resources. Since most Flink users are using Hadoop HDFS to store their data, we ship already the required libraries to access HDFS.
