The project focuses on youth, and will culminate at Willamette University for three days in June and July. There, the input of youth throughout the state will be synthesized into the Oregon Blueprint, which will be delivered to the legislature and monitored for years to come by the Oregon Progress Board.

Many people see project management as the art of trying to please everyone and pleasing no one, while trying not to go too far over deadline and too far over budget. It doesn't have to be that way. Good project management can be so predictable and reliable that it's almost boring. Here's what works in real projects.

One of the best ways in which to coerce the needs out of a user is to use an iterative prototype development methodology which is flexible enough to allow us developers to quickly build functional prototypes that can be changed to meet users newly defined or changing needs in an agile manner. When working with data this can be a complex process as data may not exist, we may not know what the back-end technologies will be, and we might not want to get locked into any particular schema. Still we would like to interpret a user’s needs and develop a prototype which gives the user the ability to ‘play’ with the application and manipulate some data, getting some feedback from the application along the way. In return, most users seem to be able to better define their needs using functional prototypes and can provide better needs information to developers. So the question arises, ‘How can I develop a functional data-driven application prototype in Flex without needing to know, well, anything about the back-end?’ The answer may be found within the Cairngorm Microarchitecture.

Scala is a functional/object-oriented hybrid language that runs on the JVM or the CLR. Scala is fully compatible with Java and brings many powerful features to the JVM, features such as: the ability to easily create DSL's due to Scala's ability to define methods for most operators, easily target multi-core hardware as Scala's types are immutable by default, access to the Actor based concurrency model, and expressive and concise code due to Scala's type inference and expressive syntax. All this without much of the boilerplate and cruft code that is so common in Java.

Why spend all that time fighting/writing code in FORTRAN/C/C++ when you could enjoy writing it in Perl instead?

Many startups underestimate the importance of a systems administrator very early on in the company's development. But maybe you're just not there yet. If you don't have a sysadmin, what is the minimum you should know to squeeze by in the meantime?

The open source ecosystem operates at human scale, and yet the most popular social networks today are mammoths, where an open source citizen has limited agency with little to no ability to change her environment. Furthermore, efforts like OpenSocial serve to further limit what independents can build outside of the major networks, culminating in a threat the very essence of what makes the open/open source community thrive: choice and marketplace competition guaranteed through the ability to fork.

The problem: you're using a modern dynamic language not known for speed, and you've identified a bottleneck. Write it in C? Does that give you the shakes? There are other language options available...

Maybe the edge isn’t as close as we thought it was. Maybe you can do some really funky things with your language without accidentally summoning eldritch spirits. Or maybe not. The only way to find out is to try it—or, if you are of the more prudent proclivities, to watch someone else try it.

Given that the database, as the canonical repository of data, is the most important part of many applications, why is it that we don't write database unit tests? This talk promotes the practice of implementing tests to directly test the schema, storage, and functionality of databases.

First, we have to understand the structure of a Joomla Core site. Joomla's content management is broken down into two basic units, the Category and the Section. (show diagram of Joomla Core) The idea here is to take as large of an advantage as we can from Joomla Core, before we move to creating anything custom. The power of Joomla is in our ability to create a website quickly and without a huge software development effort. We're going to take these navigation trees (diagrams) from a failed web development effort and quickly align them into the Joomla structure, to take advantage of what is available in Core. As we'll see, not everything will fit into this structure, and we'll have to define some custom modules which will take care of the rest. ...
