hbus is back

hbus_shot

After a month long hiatus, I finally had a chance to get hbus.ca back into a working state. The big difference is that we’re now using the official HRM transit data. Lots more remains to be done to make this site competitive for 2010 (most of the recent work has been back-end infrastructure stuff), but at least it’s usable again.


I can has Edmonton transit iPhone app?

iphone Transit to Go

Transit to Go Edmonton take 1

With yesterday’s work out of the way, there weren’t too many extra steps required before I got a basic version of Transit to Go running for Edmonton. There are definitely bugs and rough edges (the bus names could definitely be better described/formatted, and there’s some serious geocoder issues), but I think the heavy lifting is out of the way. I guess now would be a good time to open up an invitations to anyone in Edmonton with an iPhone to become part of our free private beta. We’d love to hear what you think! Just send an email to wrlach@gmail.com.


Oh, the lines! And some help for Edmonton.

A productive day on the transit development front. Finished up a few big features related to hbus.ca and Transit to Go:


Fun with WifiDog

Mar 23rd, 2010

Île Sans Fil Usability WifiDog

Because I don’t have enough spare time projects (this is a joke), I decided to take on the task of adding a must-requested special iPhone/iPod-touch friendly view for the WifiDog authentication server (used by the infamous Île Sans Fil) after being inspired by the WifiDog camp held a few weeks ago at Station C. I finally finally finished up a prototype today. It’s a bit of a hack, but a relatively clean one– hopefully some version of it can be integrated into trunk, and users with mobile devices will have a better experience when they’re on the go in Montréal (or any other area with a community-oriented wifidog deployment: I hear there’s lots).

For those interested in grubby details, you can track the progress of this work on the WifiDog ticket tracker.


Nexus One

Mar 16th, 2010

Oh glorious day, the Nexus One is now available for purchase in Canada!

I’ve been feeling less and less enthusiastic about the iPhone lately, in particular after the ridiculous lawsuit against HTC. It’s no secret that we at Navarra have been doing quite a bit of work on that platform, as have my associates at Mindsea. As long as there’s demand from our clients, that won’t change, but as an individual I’m feeling less and less enthusiastic about supporting a company that (through its actions) demonstrates hostility to the ideals of autonomy and innovation that I hold dear. Now that an attractive alternative is available on reasonable terms, I’m seriously considering switching horses in the not-too-distant future.


Adventures in processing with prender

Data Visualization

First, I’m overdue in announcing Transit to Go a.k.a. “the iPhone transit map that’s demonstrably more useful than a paper schedule” a.k.a. “your bus departure in 15 seconds or less, no matter where you are”. I wrote up a blog post about it for Mindsea‘s site, if you’re interested in finding out more.

Second, all this transit excitement has made me start thinking about better routing and geometry algorithms again. I’ve been experimenting a bit with Brandon Martin Anderson’s prender framework, used by the infamous Graphserver, and have been pretty happy with the results. It basically lets you do processing visualizations in python (i.e. no Java coding required). Here’s a quick picture of it in action, rendering the Nova Scotian road network, as distributed by geobase.

The neat thing about this framework is that you can render quickly to an arbitrary level of detail, which should prove very useful when troubleshooting the behavior of some of the code I’m working on. If anyone is interested in running the framework on MacOS X (like I was), my fork of the project has the appropriate patches.

Projects for 2010

Jan 2nd, 2010

hbus

Hurrah, 2010 is upon us!

One new years resolution I have set for myself is to blog more about what I’m working on. I’ve learned over the last year that the audience of people who care about your projects in development is vanishingly small. Thus, the need for secrecy in order to make a “PR splash” is rather small– announce far and wide when you have something that people can use by all means, but don’t worry too much about talking about what you’re working on with the internets.

In this spirit, some projects I’m 99% certain I’ll be releasing publicly in 2010:

Besides this, I have a few more irons in the fire… however, I’m hesistant to talk about them just yet. Just getting the above done in the midst of my work with Navarra (to say nothing of having a life in there somewhere) is going to be challenging.

Thoughts? Would be particularly interested in hearing from people working on similar projects to neocoder and routez. Despite how it may some times appear, I don’t have a NotInventedHere mentality: I’ve done as an exhaustive survey of the field as I could before deciding to work on my own projects, and what I’ve found just hasn’t been the right fit for what I’m trying to accomplish. However, the world’s gotten so damn big that I’m not sure if I’m missing something…

So I haven’t been blogging much lately. Story of my life, I’ll try to be a bit more active in the new year.

I’m now back living in Montréal, which has been great. Very sad to leave Halifax and all the goings on, but I’ll be back to visit. And I’m not done with disruptive transit-related apps for that city. Au contraire. More news on that soon.



Icon metaphor fail

GNOME Usability

Started to use a new piece of hardware at the Navarra office today, which resulted in the following gem being added to the GNOME notification area. Would anyone care to guess what the following icon is supposed to represent?
