Last week, eWeek ran a story listing the top open source applications of all time. Fun article.The list is pretty comprehensive, and includes a lot of projects you’d expect to see- Apache, Firefox, MySQL. I’m also pleased to say two of the projects that I talk about frequently, Nagios and Eclipse, were among those chosen. I think a few other projects not listed deserve a little recognition. Though they’re not headline grabbers, they are powerful tools that are found within a lot of software solutions, both open source and proprietary. RRDtool is a good multi-function tool that is useful for data analysis as well as clear and sophisticated reporting and data presentation. It has strong graphing capabilities and allows the user to write custom monitoring shell scripts or even create whole applications. Can’t forget about Ganglia, either. Leveraging proven technologies (including XML and RRDtool), Ganglia is a scalable monitoring tool designed to function in high-performance computing systems.Also on my own personal list of the top open source projects is Subversion, an open source version control system, Red 5, the open source flash server, and the widely-known network file transfer tool, BitTorrent. We’re all attracted to “Best Of” lists. Any other open source applications you think should have made the list? Technology Industry
