Just like other creative endeavors, software developers can experience periods of great productivity or find themselves in a rut. After contemplating the alternating periods in my own career I've noticed several factors that have effected my own professional growth and happiness, including: mentorship, structure, community, teamwork, environment, formal education, etc. Not all of the factors need to be present at all times; but some mixture of them is critical for continued growth. In this talk, I will articulate these factors, discuss how they can effect a developer's career, and how they can be sought out when missing. This talk is aimed at both new developers looking to strike their own path as well as the veterans that lead or mentor them.
== Developing a Fedora 4.0 Content Model for Disk Images ==

As the acquisition of born-digital materials grows, institutions are seeking methods to facilitate easy ingest into their repositories and provide access to disk images and files derived or extracted from disk images. In this session, we describe our development of a Fedora 4.0 Content model for disk images, including acceptable image file formats and the rationale behind those choices. We will also discuss efforts to integrate the disk image content model into the BitCurator Access environment. Unlike generalized, format-agnostic content models which might treat the disk image as a generic bitstream, a content model designed for disk images enables expression of relationships among associated content in the collection such as files extracted from images and other born-digital and digitized material associated with the same creator. It also enables capture of file-system attributes such as file paths, timestamps, whether files are allocated/deleted, etc. Further, a disk image content model suggests further steps repositories can take in order to transform and re-use associated metadata generated during the creation and forensic analysis of the disk image.
