Karate Journal Webapp Has Been Released

I finished cleaning up the Karate Journal code, and it is now available here. Two down, one to go. I hope to have the Addressbook webapp code on the site by the end of the year.

Diners Club Webapp Has Been Released

I finally got around to cleaning up and publishing the code for the Diners Club web application. Like everything else I release, I’m not sure who will actually use it. But, I find that the whole exercise of releasing your code is beneficial to you and your code. So, it’s worth the effort. It’s available via the MIT license, so have at it.

Kind of a funny side note about this project. I recently found out that a couple of co-workers of mine spend some of their spare time working on Planypus, which is a site for making plans with your friends. Sounds familiar! I was talking to them, and it turns out that Planypus started the exact same way that the Diners Club webapp started, as just a way to organize dinner outings with friends. They however took it to the next level and threw a business plan around it. I’m just not that business savvy I guess :)

TravelAgent Gnome Do plugin in the wild

I’ve just completed the initial release of my second Gnome Do plugin. It’s called TravelAgent. TravelAgent allows you to kick off searches for flights, rental cars, and hotel rooms on select travel agency websites right from Do. To use TravelAgent, you tell Do what you want to search for (flights, cars, or hotels), provide Do a simple search query string (see the plugin’s wiki page for details), and specify which of the supported travel agencies you’d like to use to conduct the search. Do will then open up a web browser, bringing you to the search results page on the travel agency’s website.

Let me just state this right from the start. I have no idea who will use this plugin, or who, if anybody, will find it useful. This is just something I wanted to do. If others find it useful, then that’s great. But, that was not my main motivation. Searching for travel can be complicated, as there are many options to consider. Take flights for example. The number of passengers you’re looking to book a flight for, and the “types” of those passengers (adults, children, seniors, etc) can vary from search to search. The departure time, arrival time, and flight time is often very important to people. Some people only fly certain airlines or certain cabin classes (coach, first class, etc). Trying to sum all of this up into a Do plugin is difficult. Do’s interface is simple…it needs to be. That’s one of the reasons why Do rocks so much. So, using the plugin had to be just as simple. To do that, many assumptions were made about the search being conducted, greatly reducing the flexibility of the search as compared to doing the search right on the travel agency’s website.

So, what is it useful for then? Well, it’s a quick an easy way to do a price check. And if you’re interested in purchasing some travel, then you can always tweak the search right from the search results page, to get it just the way you want it, before continuing down the purchase path.

As for the list of agencies supported, they are all Orbitz Worldwide agencies. All of the agencies are also running our global travel platform, which means I can interact with all of them the same way. The plugin currently works by building a URL, which contains all of the necessary search criteria, and feeding that URL to the web browser. It was the simplest way to get up and running. So, where is Orbitz you ask? Well, Orbitz is still running the classic platform. It does not have pretty URLs, or any other type of publicly available web services that I could use to conduct a search. I could write a screen scraper to get the job done, but that was beyond the scope of this initial 0.1 release. Cheaptickets suffers from the same issue. Soon, we will be rolling some of the other Ebookers agencies onto the new platform. When those sites go on, I will add support for them in the plugin. Orbitz and Cheaptickets are still a ways out, so I may look into scraping those sites for the time being.

So, what’s next for the plugin? Here’s a short list of stuff I’d like to do:

• Add support for additional OWW agencies
• Add support for searching packages (flight + car rental, flight + hotel, flight + car rental + hotel)
• Change the plugin to display the search results in Do, instead of on the agency’s search results page (but still giving the user the option to see the full search results page)
• Add support for pre-configured search options, like cabin class, preferred airline, etc. This would give the user more control over the search, while keeping the search query string simple.

I’m sure more features will come up as time goes on. We’ll see where this heads. If you have any ideas for what you’d like this plugin to be able to do, I’m all ears.

My first Gnome Do plugin

I just pushed the code for my first Gnome Do plugin. It is a plugin for Confluence, a popular wiki package, and allows you to search your wiki from within Gnome Do. Do will present you with the results, and selecting one of the results will open that page in a web browser.

I want to give a shout out to the Do developers. Because of their very powerful and flexible plugin architecture, writing the plugin was a snap. Very little code was required. I probably spent no more than 10 hours total on this plugin, and the majority of that time was spent learning the plugin architecture, and learning how to install and test my plugin.

The code is currently on its own branch, waiting to be merged with the Gnome Do community plugins branch. If interested, you can currently find the code at https://code.launchpad.net/~john-p-wood/do-plugins/confluence. Eventually, it will be merged to https://code.launchpad.net/~do-plugins/do-plugins/community.

Next up, I’m working on a Do plugin that will interact with the many Orbitz Worldwide travel websites. Stay tuned!

Release your code!

You know that piece of code that you wrote a while back? That webapp that you wrote to help organize some aspect of your life? That library you wrote to abstract away some details of a specific task? Release it! That’s right. Set it free!

One of the reasons I set up this website was to give me a way to “showcase” and release some of the code I had written over the last couple of years. I guess some part of me thought it would be as simple as tarring up the code and throwing it on the site. Well, it turns out it’s not that simple (at least for me), and that’s a good thing.

I’ve found that releasing code forces you to make it better! Over the last couple of days, I’ve found myself adding more test cases, fixing bugs, removing assumptions, bulking up the documentation, and cleaning up the code. In general, now that the code will be out there in the public eye, I want to make sure it represents my best effort. When I write code for my own use, I generally focus on keeping it clean, and making it work. I don’t usually write doc outside of the code. I sometimes make assumptions in the code based on the box that I know will be running the code. I put up with small bugs that don’t really cause that big of a problem. But at the same time, when I use somebody else’s code, I expect more. I expect good doc. I expect that the code doesn’t assume to be running in any specific environment or on any specific setup. I expect those small bugs to be fixed. So, I’ve found myself cleaning up the code to meet my own standards. And, this is great for the code.

Releasing code also engages the community. You never know who may be out there looking for something like what you have created. You could be helping your fellow man by providing a solution to a problem they could be experiencing, perhaps the same problem that prompted you to write the code in the first place. Engaging the community has several other benefits. In true open source fashion, if users feel that your code is missing something, they will often add it. If there are bugs in the code that you missed, sometimes they will get fixed. An increased user base will sometimes serve as a source of innovation. All of these end up making your code better.

So, in short, I’ve found that releasing your code makes it better! So, release that code!
