JavaLand 2015 Wrap Up After months of preparation, it all came down to three days of intense execution, and I was just one speaker. I can only marvel at the logistical acumen that was on display from the JavaLand and DOAG team. I had an action packed agenda: two conference sessions, two Early Adopter's Area (EAA) session, and one training day session. Thrown into the mix were a couple 1:1...

Programming

I thought some of you might be interested in hearing about Java and the Java dev team at a startup that's grown beyond the initial stage. Nexmo is a four year old startup headquartered in San Francisco but with the engineering team based out of techhub London; and is already one of the worlds largest cloud communications companies (cloud communications provides any application with the ability to...

Imagine if, for example, the hypervisors that run EC2 were compromised - imagine almost every business you deal with online compromised, all at once. This is the never-talked-about problem with the cloud - over on my timboudreau.com blog.

Bunyan is a NodeJS library that rethinks logging in some really useful ways. I wrote a Java port you can use in your applications. In particular, with Bunyan, logs are JSON - and Bunyan comes with a great filtering and analysis tool. The Java port uses some innovative techniques to make logging simple and foolproof - in particular, a use of AutoCloseable to make a logging code simple and...

EJB

I've just finished tuning a client's application where one of the items on the table was to find the source of calls to System.gc(). Using Censum made easy work of understanding the source of the calls. The team I was working with not only missed that these calls to System.gc() where creating havoc with their end users experience, they didn't even realize that something, some where was messing...

JSP

Validating Oracle Java Cloud Service HA One of my favorite applications from my Sun Java System Application Server days was the Cluster JSP Sample Application. In a cluster configuration fronted by a load balancer, this simple JSP provides a nice summary of which cluster node handled the request as well as the ability to test session failover. Therefore, why not try it on the Oracle Java Cloud...

I had the pleasure to review JavaServer Faces: Introduction by Example by Josh Juneau which has been published by Apress in December 2014. The highlight of the book was the simplicity with which Josh has covered some of the most complicated topics related to JavaServer Faces (JSF). I like how smoothly and seamlessly he can transition from the simple recipes to the more involved and detailed...

Distributed

Redis is good for prototyping, shared memory, messaging, caching and maximum performance. It might be used orthogonally and/or complementary to your SQL relational store, and/or NoSQL document store. For example, Redis might be used to cache dimensional aggregates of relational data for analytical purposes. It's use-case as "persistent shared memory" is important especially for microservices and...
