No One is Moving from Flex to HTML5

Very, very few Flex developers have shifted, moved, changed over, or whatever you want to call it

The fear, uncertainty and doubt (FUD) is been slung around by profiteers like folding chairs at a WWE event. The haters are still being haters. Nothing new there. But now I see JavaScript companies’ desperate pleas for Flex developers to start using their HTML5 software.

The context is all wrong here.  Very, very few Flex developers have shifted, moved, changed over, or whatever you want to call it… to HTML5 (or anything else JS-based.)

There is not a move to HTML5

I will go as far as to say that there is not a move to HTML5. The simple fact is that, developers are being developers. No matter the background, we are always trying to broadening our skill sets. This includes HTML5 since it started showing up a few years ago. For anyone to imply, or state outright, that there is some mass exodus from Flex is completely false!

The reality is still the same, Flash Player is still the most consistent cross-browser, cross-OS, and cross-device platform for software development.

It doesn’t matter if you are building business software or games, with one technology you are able to build for the desktop, Internet Explorer, Chrome, Firefox, Safari, Android, iPad, iPhone, Blackberry and Internet TVs.

What most haters fail to realize is how nice it is to go through your bug list and not find ANY bugs that are browser/platform specific. The only bugs I have, are actual bugs that I can fix. Not browser support related issues that you have no control over. For the first time in years I had to deal with browser specific issue when our On3 client embedded the application in a JSF, JSTL, ADF container. It reminded me of how good I have it. I don’t have to deal with this headache on a daily basis. In fact, it was one of the complete joys that drove me from building DHMTL development to Flex development.

So, the next time someone says, “Flex is dead” or “Everyone is moving to <insert tech here>.” Take it with a grain of salt. In all likelihood, they have a hidden agenda.

Speaking as someone who knows what's going on in more than one company :) .. some of the world's largest organizations have made strong, company-wide policy changes that they need to move off of Flex. Others don't get it yet, as you point out.

What is more telling, there is major brain drain in the Flex team at Adobe - Adobe's own people understand that Flex has no future. They are seeking greener pastures.

Organizations already struggle with the simple collection of data resulting from the proliferation of IoT, lacking the right infrastructure to manage it. They can't only rely on the cloud to collect and utilize this data because many applications still require dedicated infrastructure for security, redundancy, performance, etc. In his session at 17th Cloud Expo, Emil Sayegh, CEO of Codero Hosting, will discuss how in order to resolve the inherent issues, companies need to combine dedicated and cloud solutions through hybrid hosting – a sustainable solution for the data required to manage I...
As enterprises capture more and more data of all types – structured, semi-structured, and unstructured – data discovery requirements for business intelligence (BI), Big Data, and predictive analytics initiatives grow more complex. A company’s ability to become data-driven and compete on analytics depends on the speed with which it can provision their analytics applications with all relevant information. The task of finding data has traditionally resided with IT, but now organizations increasingly turn towards data source discovery tools to find the right data, in context, for business users, d...
Apps and devices shouldn't stop working when there's limited or no network connectivity. Learn how to bring data stored in a cloud database to the edge of the network (and back again) whenever an Internet connection is available. In his session at 17th Cloud Expo, Bradley Holt, Developer Advocate at IBM Cloud Data Services, will demonstrate techniques for replicating cloud databases with devices in order to build offline-first mobile or Internet of Things (IoT) apps that can provide a better, faster user experience, both offline and online. The focus of this talk will be on IBM Cloudant, Apa...

The broad selection of hardware, the rapid evolution of operating systems and the time-to-market for mobile apps has been so rapid that new challenges for developers and engineers arise every day. Security, testing, hosting, and other metrics have to be considered through the process. In his session at Big Data Expo, Walter Maguire, Chief Field Technologist, HP Big Data Group, at Hewlett-Packard, will discuss the challenges faced by developers and a composite Big Data applications builder, focusing on how to help solve the problems that developers are continuously battling.
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud without worrying about any lock-in fears. In fact by having standard APIs for IaaS would help PaaS expl...

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...

This has been enabled by recent advances in IoT device capabilities, messaging frameworks, presence and collaboration services, where devices can share information and make independent and human assisted decisions based upon social status from other entities. In his session at @ThingsExpo, Michael Heydt, founder of Seamless Thingies, will discuss and demonstrate how devices and humans can be integrated from a simple clust...
Who are you? How do you introduce yourself? Do you use a name, or do you greet a friend by the last four digits of his social security number? Assuming you don’t, why are we content to associate our identity with 10 random digits assigned by our phone company? Identity is an issue that affects everyone, but as individuals we don’t spend a lot of time thinking about it. In his session at @ThingsExpo, Ben Klang, Founder & President of Mojo Lingo, will discuss the impact of technology on identity. Should we federate, or not? How should identity be secured? Who owns the identity? How is identity ...
You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
