Gnome, KDE & Mono A11y

Wednesday, November 26th, 2008

Congrats Mono A11y

Many congratulations to Mono Accessibility, team for getting their first release out into the open.  The Mono A11y team must be one of the largest open-source A11y groups out there and I’m really excited about the work they are doing. WinForms and Moonlight are not yet my thing, but if Silverlight takes off the UIA provider they have created will undoubtedly form an essential part of Linux accessibility.

I don’t believe that it will be in the first release, but I’m really keen to see work start on the UIA client library for Mono. C# and Mono sound like a great place for developing new ATs.

AT-SPI D-Bus on freedesktop.org

For people who don’t know about Gnome accessibility or AT-SPI D-Bus:

AT-SPI D-Bus is a project which aims to use D-Bus instead of ORBit/CORBA as the IPC mechanism for Linux accessibility. For anyone interested in finding out about the Gnome accessibility architecture the developers page has some good information. Oddly enough KDE has a very good Gnome A11y overview, and Sun has a good diagram. Long story short the AT-SPI D-Bus aims to write a new, D-Bus based adapter for ATK, a registry daemon, and client libraries that are API compatible with the existing cspi and pyatspi.

The project has a new home on the freedesktop.org servers.

The code-base exists at:  git://anongit.freedesktop.org/git/at-spi2/at-spi2-core.git.

We are keeping a page on the linux-foundation wiki updated with all our progress. Unfortunately I’d say that the code is not yet ready for a first release. For reasons soon evident the code isn’t currently getting the love it deserves. (Help MUCH appreciated)

The reason we chose freedesktop.org and the Linux Foundation instead of Gnome hosting is that we wanted to emphasize the cross-desktop possibilities of a D-Bus based accessibility architecture.

Gnome, KDE & Mono: How it all fits together

The Mono A11y architecture diagram is missing something important that the AT-SPI D-Bus project can add – QT accessibility.

The drive to D-Bus accessibility came from ORBit deprecation, the embedded community and an ideal of cross-desktop accessibility. Its the last motive that has me most excited right now. QT currently has a D-Bus framework based heavily off AT-SPI, but unfortunately it has never been taken far enough to be compatible with existing AT-SPI ATs. The reason that the ATK, cspi and pyatspi libraries are not getting my attention right now is that I really want to get started on bringing QT into the mix.

A QT adapter for AT-SPI D-Bus will certainly round-out the Accessibility infrastructure on Linux. Not being involved in the KDE community I don’t have much say on how they do A11y, but I hope to make it as easy as possible for them to choose AT-SPI D-Bus. Along with the Mono work this could mean that QT, GTK, ATK, Winforms & Swing apps are accessible, using the same ATs, in both KDE and Gnome. I think that would be a fantastic achievement. If we work hard enough accessibility could be one of the big success stories of a joint Akademy/Guadec next year.

The book meme

Thursday, November 13th, 2008

I like this meme, its a fantastic window into how depressingly geeky we all are.

  • Grab the nearest book.
  • Open it to page 56.
  • Find the fifth sentence.
  • Post the text of the sentence in your journal along with these instructions.
  • Don’t dig for your favorite book, the cool book, or the intellectual one: pick the CLOSEST.

“Some learned people are intelligent.”

From “Mathematics for the Nonmathematician” by Morris Kline. This is actually an excellent book supposedly for non-science majors to learn about mathematics. In reality its a very nice read on the history of mathematics, with some problems thrown in.

The choice of this book was a grey area according to the rules. The closest was a copy of Nature Genetics, but this is published in volumes and so started at page 700. The next closest was a stack of books, the top one being the latest Buffy comic. I’m not sure comics count. Can anyone make a firm decision about that?

Thoughts on the US elections

Friday, November 7th, 2008

This is the first time I have been in the USA during national elections and its been a big eye-opener. During my life I’ve spent a-lot of time here, so I didn’t expect to learn as much as I did. All genuine Americans can tell me whether I stumbled upon a rather unusual election.

Presidential campaign

I met people with genuine enthusiasm for Obama, which was great to see.  People I’ve met here in Minnesota were really exited about him as a candidate, and very involved. No republicans as far as my eyes can see. Perhaps they were hiding behind a tree?

Hopefully the next UK elections in 2010 will get everyone ranting, raving and blogging just as much, but somehow I doubt it.

The only downer was his half hour political documentary. It offended my English sensibilities in so many ways. Fairness – Why does Obama get a half hour slot when Mcain doesn’t? Aloofness – I couldn’t stand the biscuit and gravy stories of real Americans. I want straight policy talk goddamit.

Al vs Norm

Here in Minnesota there was a pretty disgusting senatorial campaign between Al Franken and the incumbent Norm Coleman. Al Franken was, in his pre-political life, a comedian and writer, whose credits include SNL. The main thrust of Norm’s campaign seemed to be making Al out to be an angry, sexist, crazy man. Al on the other hand wanted to make us belive that Norm was a bribe taking crook.

Apparently this was the most expensive senatorial campaign in the country. At $30 million its getting close to an entire UK general election budget. Split that across a population of about 5 million and you get an Idea of how bombarded we were with negative advertisement. Its a relief to be watching “New connectionless light bulb” and “Conquer the neck” infomercials again.

The race isn’t over yet either. Both candidates are stuck at 42% with a recount to take place soon. I can only hope that someone in Washington just forgets about it and neither of them get the job.
