I occasionally start small projects for friends or family. I intentionally use technology I have not used before in order to learn new things. The client gets something, I learn something new. It's nice also, because it forces me to finish the projects.
Last year, I started writing a small application using the Adobe Flex SDK, (version 4, even though it was just beta when I started). The app simply streams audio and flips slide images, a Flex/AS3 component, or a customizable automatically-generated questionnaire/quiz at defined timestamps. All of this is configured through a reasonably small XML file, all via the network.
The first problem I ran into was finding a decent development environment. Adobe's Flex Builder, (based on Eclipse, now called Flash Builder), had few nice features but also some things I couldn't live with. For what it provided on top of basic Eclipse, which was almost nothing, the price was robbery.
Problems with Flash Builder 4
- It hid some of the build details too much. Flash Builder provided almost no help in writing an appropriate build/ant file. Since I wanted to be able to build from the command-line, it was not very useful to me. Lesson: Don't expect Flash Builder to jumpstart you if you are a power user. Once you leave the dock, you'll need to paddle.
- Flash Builder had no source code formatting for ActionScript, other than automatic indentation as you enter it. I don't want to spend my time formatting all of the code. I found several options, the best of which was a plugin for Eclipse/Flex Builder. However, they were all based on older versions of Flex and ActionScript 2, which had significant changes in Flex 4 and could not be used. Lesson: I am sure they will support this, if Flash Builder 4 doesn't already support it in the current build, because without source formatting (i.e. you just refactored and indentation is no longer consistent), development is annoying.
I was pretty surprised that IntelliJ was the best option, for Flex 4, at the time. I could debug, build, format source, run tests. I had more functionality from a third party, for a fraction of the price, than from the vendor alone.
Problems with Flex 4, ActionScript 3
- Many calls in ActionScript are asynchronous and have to be designed with concurrency in mind. The problem is that it's not always completely clear which calls are async. You can safely say that IO calls, such as HTTP and File requests, are async. Many things that I expected to be synchronous, (next line of code doesn't execute until the current line is done), were async, due to one or more of their dependencies being async. Lesson: Just use events (callbacks would be better) as much as possible. I got much better at this, but even examples in Adobe's live docs, (the main cause for my headaches), were only applicable in certain cases and very misleading.
- I hit a few bugs, where certain features I was using could only be called in certain ways, not in all of the ways shown in the docs. And that was fine when I was using the beta SDK. But in the fall of 2010, when I finished up, Flex 4 was released, I expected less issues. Lesson: Stay glued to the forums. Unit Test your code.
As simple as my app was, I think it had a few aspects that forced me out of my shell and it didn't give me a server backend to depend on as much, as the client is (capable of) doing more. It's quite possible that I was a tad ambitious for a first app.
Unfortunately, I waited months to finish this post so I'll have to come back with the specific bugs/issues with the language, after reviewing my notebook.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.

Developing software for the Internet of Things (IoT) comes with its own set of challenges. Security, privacy, and unified standards are a few key issues. In addition, each IoT product is comprised of at least three separate application components: the software embedded in the device, the backend big-data service, and the mobile application for the end user's controls. Each component is developed by a different team, using different technologies and practices, and deployed to a different stack/target - this makes the integration of these separate pipelines and the coordination of software upd...

The IoT market is on track to hit $7.1 trillion in 2020. The reality is that only a handful of companies are ready for this massive demand. There are a lot of barriers, paint points, traps, and hidden roadblocks. How can we deal with these issues and challenges? The paradigm has changed. Old-style ad-hoc trial-and-error ways will certainly lead you to the dead end. What is mandatory is an overarching and adaptive approach to effectively handle the rapid changes and exponential growth.

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...

The buzz continues for cloud, data analytics and the Internet of Things (IoT) and their collective impact across all industries. But a new conversation is emerging - how do companies use industry disruption and technology enablers to lead in markets undergoing change, uncertainty and ambiguity? Organizations of all sizes need to evolve and transform, often under massive pressure, as industry lines blur and merge and traditional business models are assaulted and turned upside down. In this new data-driven world, marketplaces reign supreme while interoperability, APIs and applications deliver un...

WebRTC services have already permeated corporate communications in the form of videoconferencing solutions. However, WebRTC has the potential of going beyond and catalyzing a new class of services providing more than calls with capabilities such as mass-scale real-time media broadcasting, enriched and augmented video, person-to-machine and machine-to-machine communications. In his session at @ThingsExpo, Luis Lopez, CEO of Kurento, will introduce the technologies required for implementing these ideas and some early experiments performed in the Kurento open source software community in areas ...
