Learn how to do some simple queries to extract data from the Hadoop/HDFS based HBase database using its REST API. Are you getting stuck trying to figure out HBase query via the REST API? Me too. The main HBase docs are pretty limited in terms of examples but I guess it’s all there, just not […]

I spent the last 6 months undergoing some dramatic health changes (ping me for details), primarily diet, and now I’m getting around to refactoring my fitness. Naturally, I want to try some apps that both collect lots of sensor data but that also present it back to me in a meaningful (and hopefully motivating) way. While I’m […]
I came across a couple interesting packages recently for both system and app monitoring scenarios. AppFirst Their “Beautiful Dashboards” slogan says it all – they have a free version of their DevOps Dashboard system for monitoring up to 3 servers. Among lots of cool stuff, I especially like how they show historic ranges in the […]
