The humble log has largely been thought of as a data source that is there “just in case” there is a problem. Generally logs have only ever been accessible by the chosen few, who sit in the engine room of the system looking at at log events flying past all day long. However, there is a wealth of information contained in your log data which is useful for use cases beyond debugging or security. Find...
The infamous Oscar selfie of Ellen and other celebs broke a record of 2 million retweets before midnight, March 2, and Twitter came crashing down for a record 20 minutes.

Yoav Landmand, CTO of Jfrog - the creators of open source repository manager Artifactory and software distribution platform Bintray - shares his expert analysis of Java 8, and how he thinks the next generation of software from Oracle will impact the Javasphere as a whole.
The complexity of companies’ software solutions are increasing, with developers having less and less insight into all the corners of an application. Even simple applications these days utilize a raft of tools, open-source libraries and frameworks that aid in rapid building. The disadvantage of this high velocity development, though, is the loss of visibility into what is actually happening behind...
