Contrast with commercial solutions Commercial (Tim’s NATO Mini-SSE setup): Contract, support, vendor relationship Integration challenges: vertical tendency License management: conflicts Best practice oss tools: Open source support Integration challenges: ongoing evolution DIY configuration and tailoring Which is more TCOS cost-effective? Which is easier to support? Lifecycle and evolution?

Learning curve New MDS user Establish server access MDS project approval Sysadmin action Obtain Securable web browser Java environment’t that supports CVS NetBeans Eclipse GNU Emacs etc. New TB Server Create new server zone Lesser security: Share a separate server High security: Dedicate a new server system Transport existing assets Code base into CVS Wiki and webpage information User database Server capabilities Adapt build templates to the project

Trajectory Ongoing evolution of established tools CVS: Subversion, et al. Bugzilla: Scarab, et al. Wiki:many active backend projects Apache/Jakarta: security Overall portal: full content management systems Eclipse and NetBeans: plugins Trend Increased integration among tools SourceForge less effective Natural limits on forking Continuing discussion Can co-located teams use open-source-style server tools? Out-of-band communication How to assist in expressing & sharing of software information? Accuracy, consistency, timeliness
