This last couple of months has been characterized by random bursts of productivity. After I reached all of the deliverables from my last Mozilla Foundation grant, I decided to give it another liberal reinterpretation, and have just been picking up different bits and pieces of Orca, and found stuff that interested me to work on.
Contracted Braille
This work has mostly been completed in early march. Since we are depending on an external library, liblouis, one of the most important tasks was to get liblouis into a shape that could allow it to be shipped in major distros. All sorts of distros arose, from packaging to licensing. Luckily, John Boyer has been extremely helpful, and thanks to the ViewPlus folks, we were able to get liblouis re-licensed as LGPL 3. I am maintaining liblouis and liblouisxml “forks” that are autotooled and easy to install and package for distributions. Hopefully the main development and releases will be on these autotooled versions, making users lives easier, and getting distributions to package it.
Firefox Braille Support
When I was working on the contracted braille bit, I noticed that cursor routing was not yet implemented in our Firefox support. I got basic braille display cursor routing support to work in Firefox, and also link following support. A braille display user does not have to take her fingers off the braille display to surf the web. This is neat.
Mouse Review
When I was playing with a friend’s Wii, I noticed how cool and easy it is to point and click with the controller to type in your name on an on-screen keyboard from across the room. It was easy because of the “resistance” the controller’s motor emitted. This made me think of how we could apply that in Orca: with one of those vibrating gaming mice, and with speaking the current component we could allow low-vision (maybe even blind?) users get a better picture of the graphical interface, and allow folks to use the mouse for those tasks that have no keyboard access. I thought I deserved a Nobel prize.
When I got to CSUN, I discovered that this is actually not a new idea at all. Some products already do that. Even NVDA does it by default. Mike said it would be a useful feature, so I hacked away during CSUN, and had something to show in the final days. Mouse review mode is available in development versions of Orca today, and will be in our 2.24 release.
Script Support Refactor
One of the stuff that I have been thinking about since I got involved in Orca is how do we add support for non-application customizations. For example, today it is possible for core or third party developers to extend Orca and override the default behavior and allow better access for specific applications like Evolution. We needed a way to support similar scripts, but for web applications like GMail too. When I took a look at how the source tree looked, I realized that there is an opportunity for a refactor. Last July just before GUADEC I got so excited about refactoring Orca’s codebase, that I even drew up pretty UML diagrams and attached them to a bug report. I met Willie Walker for the first time in GUADEC. He apologized for dousing my enthusiasm, but there were bigger tasks at the time than large-scale cleanups. Before CSUN we re-targeted web application scripting as a certain priority, and my refactor ideas were finally heard! The entire team stayed supportive and kept an open mind while I spliced files and created a lot of new directories. The diagram below is the UML I made last year.
About a week back I downloaded an app for my iPhone called Twinkle. It’s a Twitter client with two catches: It allows you to geotag posts, and it allows you to take attach photo snaphots of whatever it is you are doing. Both of these features make Twinkle a real great toy. It is a lot of fun browsing the twitters within a one mile radius, and trying to make out from the photos where the picture was taken. It really puts a whole new dimension to social networking.
The downside is that there is no way to relay this experience to non-iPhone users. So I made a few Yahoo pipes that mash up the photo with the proper twitters. This is my personal feed.
You could create new feeds from my pipes page.
{“pipe_id”:”67c7356101ecda7e4c351a810ee6dea8″,”_btype”:”list”,”pipe_params”:{“twitter_name”:”eeejay”,”img_width”:”320″,”img_height”:”480″}}
It used to be that when you used the Planet GNOME feed, you would get the faces and and names of the folks who were posting. For some reason this hasn’t been the case lately. Sometimes I see posts with no author names at all, and I have to click through to see who’s post it is.
This is unfortunate, because I rarely remember names, but I always remember faces. And there are a bunch of faces on the planet that I love reading.
Does anyone know why the hakergotchi and author names dissapeared from the Atom and RSS2 feeds?
