Grails without Hibernate

by Kenneth Kousen

The Grails framework is a set of Groovy domain specific languages (DSLs) on top of two classic Java frameworks Hibernate and the Spring Framework. Grails makes it easy to work with Spring and Hibernate together, using Spring to manage back-end services and Hibernate to handle object-relational mapping (ORM). Sometimes, though, you want to do database operations in Grails that don't come naturally to Hibernate, like calling stored procedures or executing your own SQL. This article discusses ways to work directly with a datasource inside Grails without going through the Hibernate abstraction layer.

Functional SOLID, Part 2

by Matt Stine

In this issue we continue our short series on the intersection of the SOLID principles of object-oriented design and programming with the functional programming paradigm. First we'll focus on the Open-Closed Principle, which tells us that modules should be open for extension, but closed for modification. We achieve open-closed designs through the use of abstraction, which in object-oriented languages is typically achieved through the use of inheritance. While inheritance can be a very powerful tool, it can also be a very dangerous one if used inappropriately. We'll learn some of the characteristics of good inheritance hierarchies from the OCP's sister principle, the Liskov Substitution Principle. Finally, we’ll examine how the use of functional composition will allow us to create modules which comply with the OCP without flirting with the dangers of inheritance hierarchies and violations of the Liskov Substitution Principle.

Demystifying Scala Extractors

by Daniel Hinojosa

At this year's NFJS Tour, I have a new presentation that I am excited to talk about — "Scala, Demystifying the Funky Stuff". The presentation distills many of the more complicated topics that can pose an issue for the new and interested Scala programmer. The presentation covers partial functions vs. partially applied functions, the Predef, type variables, implicit parameters, implicit converters, implicit wrappers, infix types, the Manifest, abstract types, type projections and type bounds. One topic that did not make it into the live presentation is Scala extractors, so for now, it will have to be housed as an article in this venerable magazine.

Greetings!

First, let me take this opportunity to thank you for your continued support of No Fluff Just Stuff. The emphasis of this magazine is all about quality content just like our software conference series. For those of you not familiar with the No Fluff Just Stuff Symposium series let me share a little history. I started NFJS in 2002 to offer high quality technical content in a conference format and offered in over 30 cities throughout the U.S. and Canada. The credo of NFJS is simply: Local Venue, World Class Conference. NFJS offers individuals the opportunity to attend an outstanding conference right in your own backyard whether you live in Milwaukee, or Denver, just to name a few. The NFJS conference series is focused on great technical content(stuff) and little to no fluff - advertising, vendors, etc...

NFJS, the Magazine is an eclectic mix of articles centered on software development and all that entails. Whether you are a developer, architect or manager, you should find all of the articles in NFJS interesting and enlightening. All of the article authors are speakers on the No Fluff Just Stuff Tour and published thereby insuring a great read. We want this magazine to be time efficient for the reader. To me, NFJS the Magazine is all about outstanding content that is easily consumable. The other great thing about the format of this magazine is that you can easily read articles out of sequence over the months and refer back to something anytime. Unlike traditional magazines, NFJS has a much longer shelf life and makes a great reference source.

We are very excited to bring you NFJS, the Magazine ten times a year. I hope you find NFJS, the Magazine to be a great informational resource. Drop me an email and let me know your thoughts.
