Create and Manage Gantt Charts with GanttProject

GanttProject is an open-source cross-platform Java application that can be used to generate Gantt charts for the management of projects. Different components of GanttProject have been released under the GPL and Apache licenses. The project is described:

The learn about document explains more of the project's features and some screen shots show some examples of what an older version of GanttProject looks like. Version 2.0.8 of GanttProject was recently announced:

Installation of GanttProject 2.0.8 on an Ubuntu 8.04 system was fairly straightforward. The software was downloaded and unzipped. The prerequisite Sun Java Runtime Environment was downloaded and installed. The ganttproject.sh startup file was given execute status and run, the application started up as expected.

GanttProject is easy to figure out. There are top-level tabs for creating charts and resources (people). Tasks can be added, assigned date ranges and a variety of other attributes. Tasks can be tied to other prececessor tasks and assigned to people. It only took a few minutes of poking around the software to create a new project, produce a simple Gantt chart and output a PostScript file that was suitable for printing.

GanttProject is not alone in its ability to generate Gantt charts under Linux. Planner is a project management tool for the GNOME desktop environment and TaskJuggler is yet another project management tool. Both of these applications have a broader project management scope. If your needs only require generating Gantt charts, GanttProject is a straightforward application that can be used to easily produce professional looking results.

Project Jigsaw (Mark Reinhold’s Blog)

Java developer Mark Reinhold blogs about the idea of modularizing JDK and other Java components. "The JDK is big—and hence it ought to be modularized. Doing so would enable significant improvements to the key performance metrics of download size, startup time, and memory footprint. Java libraries and applications can also benefit from modularization. Truly modular Java components could leverage the performance-improvement techniques applicable to the JDK and also be easy to publish in the form of familiar native packages for many operating systems. Finally, in order to realize the full potential of a modularized JDK and of modularized applications the Java Platform itself should also be modularized." (Thanks to Nicolas Mailhot).

Let's talk about Python 3.0

For those who are questioning the value of Python 3.0: James Bennett has posted an interesting discussion on why it is worthwhile. "It's rare that any large/established software project manages to overcome this inertia and actually take stock, figure out whether 'the way we've always done it' is still a good way to do it, and then make changes in response. This week Python 3.0 was released, and it represents one of those rare instances: Python 3.0 was designed to clear up a lot of now-inertial legacy issues with the Python language and figure out good ways to do things now instead of unquestioningly sticking with what seemed like good ways (or, more often, the least painful ways) to do things five or ten years ago."
