New maintenance version of GemDev 0.2.2 is available. This release is backward compatible with existing server side scripts (from 0.2.0 release). Please check GemDev page for details on installation/upgrade instructions and links.
Programming and System Administration Guides (which you may want to check when watching videos) are available for example from GemStone/S Documentation site.
UPDATE: added link to summary of all parts of Scaling Objects presentation
During my research on libraries for visualization of large bodies of source code I came over two interesting projects. These projects focus on visualization of whole repositories and results seems more like an art than just pure technical thing…
code_swarm
code_swarm is “organic software visualization of project repositories” for SVN, CVS, Git and other VCS. Examples for different open source projects can be found here.
Below is a year old video presenting GemDev features in real time. Video was recorded for internal presentation of previous version (0.1.9), but it covers most features of recently released 0.2.0. Recording was done with free GLASS version of GemStone/S running in VMware Appliance and Eclipse 3.4.
It should be noted that if you will use GemDev for example with big remote DB you will not always be able to reach same quick response as is on video. This video uses very small DB (coming with free version) and is running locally in VMware. With bigger remote DBs it can take longer time mainly when connecting to DB or searching for references/implementors/senders. Usual browsing/editing is not affected so much and overall speed is still very acceptable.
