Note to Self Blog

Posted by jive May 24, 2012
One of the Open Source Geospatial Foundation (OSGeo) email lists is reviewing relationship between OS and IP. Again. I am a big fan of matching license to community. While I recognise that open source and intellectual property can be considered as opposites - I find myself lumping them both together. Rather then recycling this viewpoint, here is a note to self (allowing me to supply a link):

Note to Self: Open Source / IP

Open source is a part of the intellectual property conversation. Open Source and IP deliberately go together; indeed it is what the license part of open source is about. Open Source provide a range of licenses which provide guidance around the use (and reuse) of code. These licenses facilitate, by defining the terms under which, which we can reuse / recycle code with the permissions of the authors (i.e. copyright holders). Since OSGeo is an open source community we often have direct contact with these authors; in a few cases they have signed over copyright to a neutral organisation - such as the OSGeo foundation itself. It would be nice if software worked like the fashion industry and did not make use of copyright protection. Since our industry does make use of these provisions - it is great that open source allows us an "out". The specific nature of the open source license used by a project lets you know what has been negotiated with the authors with respect to IP. Depending the different aspects of the IP spectrum you agree with you may react strongly (or indifferently) to the options available. You can even use this as a measure of what you care about (either from the case of trying to protect; or from the case of trying to access). For myself I try protect the freedom of developers to get the job done. Open source is one of my best tools to protect this freedom. Another valuable tool is the different foundations. You can tell a lot from the a foundation and its members by what makes their hit list when accepting new projects. OSGeo is very much about transparency; but not so much on the protecting developers from IP issues. Eclipse foundation suffers on transparency a bit; but is very responsive to protecting developers from IP issues. Aside: The uDig community is looking at joining the Eclipse "location working group". It is a good fit of technology, open source spatial outreach, and access to a pool of developers we do not normally interact with. Perhaps when this process is done (or even started) we can provide further feedback on the experience.

ObjectAid Blog

Posted by jive Apr 11, 2011

ObjectAID is the first UML tool you may actually use; I know I should talk about its features or something - but the real reason you may actually use this application is that it is Fast.

1. Run the wizard to create a new diagram

2. Drag and Drop your classes into the diagram

3. I have found the "auto image" setting helpful so it writes out an image (PNG,GIF,etc..) every time you make a change.

Here is one of the many diagrams pulled together for the GeoTools User Guide I have been rewriting.

You can install ObjectAID from the eclipse marketplace (in the help menu).


FindBugz Community Review Blog

Posted by jive Mar 13, 2010

I am very fond of FindBugz (indeed it has found its way into the QA process of most projects I work on....). When visiting the site to check Eclispe 3.5.2 compatibility I found they were working on a new tool.

Indeed a very interesting tool.

Looks like they have a specific tool for browsing the output of a findbugz; and sifting through the results in order to mark each issue. They have an example for Eclipse 3.5 listed.

Now I think I get this result when I run FindBugz direct in eclipse (it produces a bunch of warnings for me to sift through). What is interesting is the Classify and First seen fields. It is my hope that this tool can be hooked into the bug tracker for each project allowing people to raise an issue directly for review.



How 2 Map Blog

Posted by jive Apr 8, 2008
I will be using this blog a little less; it seems the vast majority of my postings are of interest to those involved in open source spatial (and Java is just the canvas I enjoy working with). As such I will be making use of the following blog: http://how2map.blogspot.com/. I would like to thank Java.net for hosting, and hope the spam comments problem abates.

The code always knows Blog

Posted by jive Feb 20, 2007
I have had to field this question a couple times in the last week; most recently from a old GeoTools buddy by the name of Cameron. Apparently I am working on Open Location Services and he knows a buddy who is working on the same thing. How would you answer a question like that? We all know the default answers, they form mantras for the open source movement. Things like many eyeballs just don
