Yesterday I had the pleasure of speaking at the superb European Ruby Conference in Barcelona.   It was fascinating seeing the enthusiasm of the audience for Ruby and the technologies presented.  I also got to talk to several attendees about their own Ruby efforts.   The most interesting chats that I had were reminders of how device capabilities on mobile are constantly expanding.  This will be a constant thread and area of continued development and innovation for Rhomobile. For example, I talked to Bart ten Brinke and other developers from Nedap Healthcare about their mobile home healthcare monitoring and timekeeping software.  It runs via the builtin RFID on the nurse’s mobile. They swipe the patients card over the phone to check in and check out during their visit.   Right now it’s only J2ME based for Nokia’s Series 40 RFID-embedded featurephones.  But the forthc...

UDDI as an Extended Web Services Registry

As enterprises build a critical mass of Web services, they need some way of keeping track of those services. UDDI is an ideal store for such information. Using UDDI's built-in abstractions of business services, binding templates, and tModels referring to interface specifications, UDDI can be used to manage all of the addresses and protocols and formats of those services. This information can be used for several purposes, including providing location independence and identification of common supported interfaces among those services. But the amount of information tracked on each W... (more)

Beyond Point to Point

Web services have emerged as an excellent method of integrating pairs of applications. Free and cheap Web services development tools from many different vendors make it easy to expose one application's capabilities to other applications that wish to invoke them. But, given recent trends and innovations in Web service standards for more complex integrations of multiple applications from many parties, integrating applications two-by-two with tightly coupled simple Web services may not be the best approach. In this article, I'll take a look at a reasonably complex integration scena... (more)

RhoHub: GPL and Dual Licensing

We’ve had over a thousand customers sign up to the RhoHub service over the last month since we launched on November 4th at the iPhone Developer Summit. They are now asking “ok I’ve built my app really quickly. Now what do I need to do to distribute it on the App Store or elsewhere?” We ask that you either open source your app by making the source public and putting a GPLv3 license on it (we’ll automate this latter step soon). Or purchase a commercial license if you want to keep your source private. Some people say “oh, you’re dual licensing like MySQL. So does that mean that I g... (more)

“but isn’t HTML5 enough?” – why mobile usage will always be about native, not web, apps

I’m here at RailsConf 2010. What a great place to talk to current and prospective Rhodes developers! Rails developers all get why its important to have a full Model View Controller framework. They also get pretty excited about the presence of the first mobile Ruby on every smartphone device. Rails developers get the value of Rhodes deeper than any audience I’ve encountered. A couple of the other talks, from otherwise insightful web framework developers, who apparently have “smartphone envy”, were disturbing. One speaker talked about his efforts to make Rails a little better for ... (more)
