Permalink Problem

The previously mentioned problem with attachment posts is related to a permalink bug in WordPress. Permalinks containing categories (e.g., /archives/%category%/%postname%/) will pose problems for any attachment posts. This is due to the fact WordPress does not allow category management for these posts and thus they end up in the uncategorized category. If this category is not the primary category of the parent post, then the resulting permalink will break. A fix may already exist for 2.2. Regardless, I’ll keep digging into this so that 2.3 will not contain this problem.

Gentoo Blue Wave

Posted by John Havlik in Art

A while back while reading a tutorial by Nick La of N.Design Studio, I thought the concept of what his tutorial covered in Adobe Illustrator was cool. Of course, using Illustrator is not an option when running in a GNU/Linux environment. This is where Inkscape comes into play.

Much like the GIMP, Inkscape does not do everything that its Adobe competitor does. Thus, abiding strictly to Nick’s tutorial is impossible, but getting to the same end result is possible. In the coming weeks I will post a supplement to Nick’s tutorial for the use in Inkscape. However, right now I’m introducing the end result of my Inkscape experimentation, Gentoo Blue Wave. This is a 1080p resolution wallpaper that abides to the Tango pallet. This is released under the Creative Commons Attribution-Noncommercial 3.0 License.

Developing WP Trainer

Posted by John Havlik in WordPress > Plugins

The rather unfriendly weather this weekend provided a rather good opportunity to begin coding WP Trainer. Contrary to previous thoughts, my previous experience with RSS has helped little in working with the XML parser in PHP. Thus, getting the Garmin output XML file into a nice array of objects in PHP took a bit of time, but now that part is done. Now comes the learning of the Google Maps API, which has excellent documentation and looks like it will be easy to do. After that I’ll need to select a graphing API. Mootools does not have graphing capabilities so using that is out besides AJAX and effects stuff. If anyone knows of a good, fast, and lightweight javascript/SVG API for doing all sorts of graphs let me know.

Expect a beta for WP Trainer sometime near the end of this month, with a preview available on this blog in the coming weeks. Corresponding to this release I will rework moo.wp and the available download will correspond to the featured description. At the time of release API documentation for moo.wp will be available for theme and plug-in writers. Features described in the API documentation are guaranteed to remain the same for three WordPress major releases (e.g., 2.0.0, 2.1.0, 2.2.0, etc.) and will remain available for at least one year.

Breadcrumb NavXT is starting to get hits, Micheal did get a forward link going which has spurred that traffic. All of the various WordPress plug-in sites need to be updated, which means I probably have some e-mails to write. Anyways other that WordPress 2.3 support for 1.9, which includes the new tagging system, some more advanced length limiting techniques will be available. These include maximum total breadcrumb length and options on where and what to trim.

One last thing, I do realize that Internet Explorer 6 (and maybe 7) messes up the header on this blog, the simple solution to this is to at least upgrade to IE7, and think about switching to Firefox. Opera users will see that the footer is messed up, I am working on this but it may not be resolved for a week or so. I can not test for KHTML based browsers (e.g., Konqueror and Safari) right now so their status is unknown, but assumed to work.

Breadcrumb Navigation XT Version 1.8.0

Posted by John Havlik in WordPress > Plugins

Since the original author of Breadcrumb Navigation XT ran out of time for further development of the WordPress plug-in, I have picked it up. After a few days of coding and working on setting up the code section of this blog, the new version is ready for release. This new version, 1.8.0, includes support for author pages, and limiting the number of categories displayed in the breadcrumb.

Note that beginning with this release the version numbering scheme is to follow the same as WordPress uses, the first digit changes for major changes and as the second runs past 9. The second digit changes with the addition of features, internal structure of the class will not change in with a change in this digit. Finally, the third digit signifies a bugfix to features previously introduced without any added features. The next version, 1.9, is planned for the release of WordPress 2.3 due to the addition of tags into WordPress.

Check out the Breadcrumb NavXT project page to get the latest version.

Happy Summer Solstice

Posted by John Havlik in General

Yep, the current season for the northern hemisphere is now summer. It would not be summer with out the sun, our local star.

And speaking of stars, the star Eta Carinae made its way on to the front page of Digg twice today. Eta Carinae resides at about 7500 light years away from Earth. Back in the 1840s the light from a supernova like explosion on Eta Carinae reached Earth. Now with composite pictures from NASA excitement over this star is increasing. According to Phil Plait, from Bad Astronomy, Eta Carinae should produce a gamma ray burst in its supernova event. A steady diet of these high-energy rays will kill all living inhabitants of Earth. Don’t panic, according to Phil the most likely directions for the gamma rays to be emitted during the event are not aimed directly at us.
