A list of the Open Source Titles I've used over the last many years. This is a dynamic list that will keep growing as I add more titles and discover other great free tools. They will appear in no particular order.
Libreoffice is a free suite of tools very similar to Microsoft Office. I've used LibreOffice and it's predecessors OpenOffice, StarOffice and the Mac NeoOffice for many years now. I've always found them to be great tools and superb alternatives to the more expensive MS Office line. I've even used the drawing tools in LibreOffice (Draw) to produce some very accurate scaled CAD drawings.
LibreOffice is the free power-packed open source personal productivity suite for Windows, Macintosh and Linux, that gives you six feature-rich applications for all your document production and data processing needs.
Inkscape is a great, FREE professional-grade vector drawing program much like the powerful industry standard Adobe Illustrator. I use it quite extensively in my technical writing work to produce annotated graphics, scaled drawings, logos and misc graphics. Inkscape is vector-based so drawings can be easily re-scaled without losing quality and can be exported in PDF and any number of different bitmap formats.
GIMP is perhaps the second most used software in my personal toolkit. Many years ago I took a course in Photoshop, but could never afford the software, then I came across GIMP that does probably 85% of what PS can do and there are many plug-ins to bring it even closer. Give it a try, here is the GIMP official description from their website.
GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software for such tasks as photo retouching, image composition and image authoring. It works on many operating systems, in many languages. ( more...) This is the official GIMP web site. It contains information about downloading, installing, using, and enhancing it.
Although not as powerful as Visio, but a heck of a lot less expensive Dia allows users to create flowcharts and org charts with relative ease. I've used it with some success to create structured diagrams for some technical writing projects.
Dia is free (open source) drawing software. Sketch your favorite structured diagrams! Windows version available as a free download.
Another one of those tools that are almost always with me Greenshot is a very versatile screencapture program with the ability to grab a portion of a screen, a window or the entire desktop much like any other screen grabber. What sets Greenshot apart for me are the annotation tools and also the fact that it can instantly send images to one of many social networks.
What is Greenshot? Greenshot is a light-weight screenshot software tool for Windows with the following key features: Quickly create screenshots of a selected region, window or fullscreen; you can even capture complete (scrolling) web pages from Internet Explorer. Easily annotate, highlight or obfuscate parts of the screenshot.
Need to create a brochure, business cards, a newsletter for your local neighbourhood club or perhaps your department or even company, Scribus can do all that and more. I have personally used Scrubus to successfully create a very complex Newsletter for a Writer's association.
Underneath a modern and user-friendly interface, Scribus supports professional publishing features, such as color separations, CMYK and spot colors, ICC color management, and versatile PDF creation.
Wink is a tutorial and presentation creation software.
Need to create on-line tutorials and explain how software works or would like a way to create an immersive experience while explaining a concepts, then Wink may be for you. Wink allows a user to do a screencast while recording mouse movements and even adding voiceovers. The post-recording editor also allows annotations of the screens. Very versatile software
KompoZer is designed to be extremely easy to use, making it ideal for non-technical computer users who want to create an attractive, professional-looking web site without needing to know HTML or web coding.
OK, perhaps not strictly really an application in the traditional sense, it is however open source and I do run several blogs and websites using this infamous CMS. If you haven't tried it, give it a go, there's plenty of great information out there to help you along as well.
Developers love to use open source tools for making their development task easy. Generally, open source development tools are available for free-of-cost and can be modified the way developer sees robust.
