Hortonworks has quietly made available the DataFlow platform which is based on Apache NiFi and attempts to solve the processing needs of the IoAT.
Ratpack, a high performance Java web framework, has reached 1.0 status. The 1.0 release is API-stable and can be considered production ready. The main thing that makes Ratpack interesting is the execution model, which aims to make asynchronous programming on the JVM easier.
Pivotal announced a complete re-design of Spring XD, its big data offering, during last week’s SpringOne2GX conference, with a corresponding re-brand from Spring XD to Spring Cloud Data Flow. The new product is focussed on orchestration.
At the combined Agile Alliance and Agile Open Northwest Open Space event in Portland Declan Whelan and Diana Larsen led two sessions in which they explored the application of the Agile Fluency model for understanding and addressing technical debt and showed a game based on the model which teams can use to help them identify practices and principles they want to adopt based on their fluency goals
An agile workplace is one that is constantly changing, adjusting and responding to organizational needs. How to create an Agile workplace and what are the benefits.
ARIN, the resource registry that hands out allocations for IPv4 addresses, has announced that it has no more IPv4 addresses to give out. Although this doesn't mean no more IPv4 addresses will be allocated, it has brought to an end the question of when such addresses will run out. Meanwhile, IPv6 usage continues to climb with the release of iOS 9.
In theory the operations team determines what the thresholds for warnings and alerts should be. But in practice, the operations team often have no idea what these values should be. Using machine learning techniques such as adaptive thresholds, Splunk ITSI solves this problem.
The DBA’s primary job is to ensure that the business’s information is always available, with performance coming in at close second. We’ve already talked about optimizing distributed queries in Splunk and map-reduce queries in Hunk. In this report we expand upon that with more information that a DBA needs to know about Splunk databases.
Swiss Postal Services has used scaled Scrum with seven teams to replace a legacy system.

Optimizing queries in Splunk’s Search Processing Language is similar to optimizing queries in SQL. The two core tenants are the same: Change the physics and reduce the amount of work done. Added to that are two precepts that apply to any distributed query.
A surprisingly common theme at the Splunk Conference is the architectural question, “Should I push, pull, or search in place?”
If you could handle all of the data you need to work with on one machine, then there is no reason to use big data techniques. So clustering is pretty much assumed for any installation larger than a basic proof of concept. In Splunk Enterprise, the most common type of cluster you’ll be dealing with is the Indexer Cluster.
During the second technical keynote at SpringOne2GX last week Guillaume Laforge talked about plans for Groovy 2.4.x and 2.5. Perhaps the most significant is improved compiler performance with a new Abstract Syntax Tree (AST) class reader in place of using class loading tricks.
