10 Principles for Software Estimation : It Does not have to be that hard!
As developers we dread when management requests a project estimate. Typically, you do not have the opportunity to understand all the requirements, the team composition is unknown, and you have been given until tomorrow end of day to produce an estimate. Several months later everyone is yelling at you about the software estimation errors encountered during the project.
10 Things you should know about Software Risk Management
Once you leave academic “hello world” projects, software development is full of unknowns which result in the high rate of project failure we see too often in industry. This presentation will cover 10 principles of software risk management necessary for project success.
Groovy Closures - The way to cleaner code
The factory patterns and callbacks have been around for a long time as a technique to provide flavor specific code variations. But they are awkward and hard to update. Enter Groovy closures. Imagine having the ability to inject different coding flavors using code closures. If you need a different flavor, then just pass a different code block. Now imagine that all of this works on the JVM!
Promoted to Technical Lead - Now what do I do?
When you think about technical leadership positions do you empathize with Peter Pan?
“..I won't grow up,
(I won't grow up)
I don't want to wear a tie.
(I don't want to wear a tie)
And a serious expression
(And a serious expression)
In the middle of July.
(In the middle of July)
And if it means I must prepare
To shoulder burdens with a worried air
Fear not..Development is fun for sure…but technical leadership has many more interesting challenges to keep you learning and challenged. Technical Leadership positions are not just about telling people what do! The role also includes; sharing your technical experiences with others, learning new technologies from your team members, working with stakeholders to help ensure that the right product is developed.
Developing Web Services Quickly using GroovyWS

The Software Manager's Dashboard: Getting the information you really need
When we start a project, our management hands us a copy of MS Project and using this tool we are expected to accurately track the project to completion. What often ends up happening is many of the project tasks are listed as 90% complete and you don't have a clear understanding of the blocking reasons. This presentation will explore various vendor independent time efficient dashboard options you can pursue to properly track your project.
