Last week I wrote a couple of tools to keep track of subversion checkins:

The Subversion Log Viewer is a master-detail list of recent subversion revisions. It’s based on the OpenLaszlo contactlist example. The nicest feature is really an afterthought: at the last moment, I added faces for authors; I think this makes projects a lot friendlier. Right now it only adds the faces to the OpenLaszlo log; let me know if you’re interested in using this for your own project, and I’ll make a public API for adding faces to a repository.

The Subversion iCalendar Gateway transcodes subversion logs into iCalendar files, that you can subscribe to with Apple iCal or Mozilla Sunbird. I find it useful for a projects that I want to check in on occasionally. Unlike an RSS feed, it gives you a sense of the activity level and the change frequency, at least if you’re a spatial person like me.

Both of these point at the OpenLaszlo log by default, but they’ve got a UI for putting in any subversion repository (http: or svn: protocol only), and generating a permalink for that repository.

One caveat: It takes a long time to request a complete subversion log, so the iCalendar gateway only requests the first 500 revisions the first time you (or anyone) view a given calendar, and then the next time anyone or refreshes the same calendar, it catches up to the present 500 revisions at time.

Google for "unfortunately, yournamehere":

Lots of fun hits for "unfortunately, jim":

I’ve turned this into a web page here.

I prototyped it with a screen scraper for Google, but I didn’t want to deploy a screen scraper.

Fortunately, Google has a Search API.

Unfortunately, Google’s API uses SOAP.

Fortunately, Ruby has a SOAP library.

Unfortunately, the Ruby SOAP library doesn’t work on Dreamhost.

Fortunately, the Yahoo Web Search API uses REST.

Unfortunately, Yahoo’s summaries don’t include enough right-hand context, so it’s harder to extract decent sentences from them.

Maybe I’ll go back to screen-scraping after all.

Update: Jim tells me he got the idea from Jorg Brown at Google.

Expialidocio.us is a tool for visualizing your del.icio.us posting activity. It displays a graph of your posting activity over time. You can select a timespan from this graph, and it will show you a tag cloud weighted by just those dates.

Expialidocio.us was inspired by a posting by Jon Udell. Coming full circle, Udell has posted since posted about this application. Since then, I’ve published the sources.

openlaszlo.rb is a Ruby library for compiling OpenLaszlo programs. I use it to build this, this, and the toolbar here. This article describes how to use it with Rake.

Update: This is now available as a gem. The rdocs are here.
