Living Code

[Update: Thanks to Blake Winton for pointing out that the project page link to the Pastels download was broken, fixed now. Also added a link to the project page.]

Pastels is an example project for creating an OS X screensaver in Python using PyObjC. By extension it could be used as an example for building nearly any plugin or bundle for OS X. It started when I had an idea for drawing a simple squiggle, over and over, while cycling the colours and moving the squiggle around. I was very pleased with how it turned out.

It’s also my first attempt at hosting an open-source project at Google with their new hosting program. If it works out well I will add more of my projects there, which will save me trying to set up and configure Subversion on Dreamhost for public access (probably not difficult, but one more thing I don’t have to do means more time for writing example code and tutorials).

I’m working on the tutorial text to go along with this project, so ask any questions you have and I’ll try to get to them in the tutorial.

If you are seeing this on my site (as opposed to the Atom feed), there are some changes I’m making to the site that I’d like to point out. I’ve added pages for projects and mini-projects which use the same stylesheet and includes as the rest of the site. I know the stylesheet is uglyless than completely attractive right now–the first thing was to get everything factored and consistent, then to make it pretty. The projects page only has one item on it (Pastels), but that should be changing now that I have the infrastructure set up the way I want it. Nearly all the projects I mentioned in my presentation at the Vancouver Python Workshop will get their own pages soon. More about that in my next post.

My latest article for David Mertz’s column XML Matters is up at IBM developerWorks: Lighter than microformats: Picoformats Ajax without X, Microformats without angle brackets went live a couple of days ago. It isn’t so much about XML as how to avoid XML. My feelings towards XML are that it is useful and good, but overused and not a panacea. By providing some alternatives, maybe some of the backlash against the “XML everywhere for everything” meme can be averted.

I’ve been meaning to post about the article, but I keep getting caught up preparing my presentation for the Vancouver Python Workshop on Saturday (the workshop starts Friday August 3rd and goes through Sunday August 5th). My talk this year is on using [PyObjC] to create applications and plugins for OS X using Python. I’ll get the slides up after, as soon as I can. I’m also planning on doing a shorter version of this talk at Bar Camp Vancouver which is 6 pm Friday, August 25 to 6 pm Saturday, August 26.

And I should have mentioned the Google talk at the Vancouver High Performance Computing User Group before it happened on July 27th. Narayanan ‘Shiva’ Shivakumar came up from their Seattle office to present mostly old information from their published papers such as The Google File System, MapReduce, and BigTable (video). The talk over beers after was fun, and it was good to see my friend Mark and find out he has a blog, even if it’s over my head much of the time.

Well, that’s my update dump. More stuff on actually using PyObjC coming Real Soon Now.
