Michael Yuan's Java Blog: "Is Ruby Replacing Java? – Not So Fast"

"I do not think [RoR] will replace Java in web applications."

Is Ruby Replacing Java? – Not So Fast

Okay, I have heard it all: Ruby On Rails (RoR) is so much cooler and simpler than Java EE. It allows you to write web applications 10X faster. And Ruby has nifty language features we can only dream of in Java. So, Ruby must be replacing Java to become the "next" programming language just as Java "replaced" C++/COBOL and C++ "replaced" Fortran.

Well, in my opinion, this kind of talk has some serious logical problems. First of all, as the short history of high technology has proven again and again, the "superior" solution does not always win over "inferior" ones. In fact, the opposite is more likely to be true. The question regarding to Ruby versus Java is NOT how much more advanced RoR is compared with Java EE -- the real question is whether Java EE is good enough for most developers.

The reason, in economics terms, is that the choice of a technically "better" programming language does not bring you competitive advantage in terms of overall cost and productivity. Instead, it matters far more to have better requirement gathering, better customer feedback, better development process, better trained developers, and better development tools (e.g., IDEs). In software engineering speak, the actual implementation of a system using a specific programming language has the lowest value in the value chain, and can be easily outsourced.

Okay, now you may ask: "If that is true and programming language does not matter, how come Java became so successful and replaced an array of older languages?" Well, did Java really "replace" any other language? I have recently been in graduate school for a science PhD program, and all the new bleeding-edge number crunching software we wrote was still Fortran. It is not being replaced by C++ or Java. Fortran is good enough and switching to a cooler language does not make scientific computing better / faster -- and the re-training cost for the entire team eliminates any potential productivity gain. Another example: for rich UI application developers, the dominant languages are still C / C++ / VB. Even heavily marketed languages like C# and VB.Net have little traction -- let alone Java.

So, my observation is that one language does NOT replace another one. The rise of a new programming language always comes with the opening of a new application area and an influx of new developers who are willing to try out a new language -- since there is simply no incumbent language in this brand new area. That is, you need to grow the big pie to make room for new languages. Fortran rises with scientific computing; Cobol rises with business computing; and Java rises with web applications. Is there a brand new computational field opening up for mass Ruby and RoR adoption? No. The software industry is not on the verge of another big expansion.

Now, Ruby is good at simplifying the development task for an already simple problem -- build simple database driven web applications. I firmly believe that Java is already good enough in this area. There is nothing a RoR web site can do that a Java web site cannot (Granted, there are things the Ruby language can do but Java cannot. But that does not concern web users in front of a browser). Java just takes a little more time for *beginners* to get started, and it scales to the high end and legacy applications. The cost to re-train the developers for RoR (language, framework and IDE tools) would not really justify the productivity gain. And work-arounds to scale RoR applications could be very costly.

Having said that, of course, Ruby and RoR are important technologies to learn in two aspects:

  • The most important impact Ruby/RoR will have is to drive the innovation in Java EE -- much the same way C# drives the Java 1.5 innovation. We are already seeing this happening.
  • For people who need to build many web sites quickly, e.g., consultants and startups, Ruby/RoR is a great tool to try out the ideas and get a quick beta/prototype to the market.
  • So, while I encourage every Java developers to learn Ruby / RoR, I do not think it will replace Java in web applications. Anyway, just my 2c.

    There will be 50 billion Internet connected devices by 2020. Today, every manufacturer has a propriety protocol and an app. How do we securely integrate these "things" into our lives and businesses in a way that we can easily control and manage? Even better, how do we integrate these "things" so that they control and manage each other so our lives become more convenient or our businesses become more profitable and/or safe? We have heard that the best interface is no interface. In his session at Internet of @ThingsExpo, Chris Matthieu, Co-Founder & CTO at Octoblu, Inc., will discuss how these devices generate enough data to learn our behaviors and simplify/improve our lives.

    Last week, while in San Francisco, I used the Uber app and service four times. All four experiences were great, although one of the drivers stopped for 30 seconds and then left as I was walking up to the car. He must have realized I was a blogger. None the less, the next car was just a minute away and I suffered no pain. In this article, my colleague, Ved Sen, Global Head, Advisory Services Social, Mobile and Sensors at Cognizant shares his experiences and insights.
    We are reaching the end of the beginning with WebRTC and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) irreversibly encoded. In his session at Internet of @ThingsExpo, Peter Dunkley, Technical Director at Acision, will look at how this identity problem can be solved and discuss ways to use existing web identities for real-time communication.
    Can call centers hang up the phones for good? Intuitive Solutions did.

What business, social and practical implications will this phenomenon bring? That's the subject of "Monetizing the Internet of Things: Perspectives from the Front Lines," an e-book released today and available free of charge from Aria Systems, the leading innovator in recurring revenue management.
    The Internet of Things will put IT to its ultimate test by creating infinite new opportunities to digitize products and services, generate and analyze new data to improve customer satisfaction, and discover new ways to gain a competitive advantage across nearly every industry. In order to help corporate business units to capitalize on the rapidly evolving IoT opportunities, IT must stand up to a new set of challenges.
    There’s Big Data, then there’s really Big Data from the Internet of Things. IoT is evolving to include many data possibilities like new types of event, log and network data. The volumes are enormous, generating tens of billions of logs per day, which raise data challenges. Early IoT deployments are relying heavily on both the cloud and managed service providers to navigate these challenges. In her session at 6th Big Data Expo®, Hannah Smalltree, Director at Treasure Data, to discuss how IoT, Big Data and deployments are processing massive data volumes from wearables, utilities and other machines.
    All major researchers estimate there will be tens of billions devices – computers, smartphones, tablets, and sensors – connected to the Internet by 2020. This number will continue to grow at a rapid pace for the next several decades. With major technology companies and startups seriously embracing IoT strategies, now is the perfect time to attend @ThingsExpo in Silicon Valley. Learn what is going on, contribute to the discussions, and ensure that your enterprise is as "IoT-Ready" as it can be!

The P2P shift will impact many areas of our lives, from mobile communication, human interactive web services, RTC and telephony infrastructure, user federation, security and privacy implications, business costs, and scalability. In his session at Internet of @ThingsExpo, Erik Lagerway, Co-founder of Hookflash, will walk through the shifting landscape of traditional telephone and voice services to the modern P2P RTC era of OTT cloud assisted services.
    While great strides have been made relative to the video aspects of remote collaboration, audio technology has basically stagnated. Typically all audio is mixed to a single monaural stream and emanates from a single point, such as a speakerphone or a speaker associated with a video monitor. This leads to confusion and lack of understanding among participants especially regarding who is actually speaking. Spatial teleconferencing introduces the concept of acoustic spatial separation between conference participants in three dimensional space. This has been shown to significantly improve comprehension and conference efficiency.
    The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, will discuss single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example to explain some of these concepts including when to use different storage models.
