Significant Software Development Developments of 2012

I have written before (2007, 2008, 2009, 2010, 2011) on my biased perspective of the most significant developments in software development for that year. This post is the 2012 version with all my biases and skewed perspectives freely admitted.

10. Groovy 2.0

Groovy 2.0 have been an important version for Groovy. Groovy 2‘s arguably most notable new features are its static type checking and static compilation capabilities.

9. Perl Turns 25

Perl celebrated its 25th anniversary in 2012. Love it or loathe it, Perl has definitely become the predominant scripting language, especially in the non-Windows environments. Perl is not my favorite (I’d rather use Groovy, Python, or Ruby), but I find myself needing to use it at times, usually because I’m modifying or using an existing script or set of scripts already written in Perl. Happy Birthday, Perl!

8. Git and GitHub

Git is the trendy choice now in version control and GitHub is equally trendy for hosting code. The post Why Would Anyone use Git in their Enterprise? states, ‘Git has a cult-like following in the development community.’ The book Pro Git (2009) is freely available for reading online and can be downloaded as a PDF, mobi, or ePub electronic book.

7. NoSQL and Polyglot Persistence

The NoSQL concept seems to be maturing and moving from unabated hype and hyperbole to understanding when it works well and when it doesn’t. In 7 hard truths about the NoSQL revolution, Peter Wayner writes: NoSQL systems are far from a perfect fit and often rub the wrong way. The smartest developers knew this from the beginning. … the smart NoSQL developers simply noted that NoSQL stood for ‘Not Only SQL.’ If the masses misinterpreted the acronym, that was their problem.

Martin Fowler‘s nosql page states: ‘The rise of NoSQL databases marks the end of the era of relational database dominance. But NoSQL databases will not become the new dominators. Relational will still be popular, and used in the majority of situations. They, however, will no longer be the automatic choice.’ With this, Fowler introduced the concept of polyglot persistence (which he mentions was previously coined by Scott Leberknight in 2008) and explicitly compared this to the concept of polyglot programming. If we as a software development community believe that the advantages of using multiple languages in the same application (polyglot programming) are worth the costs, then it follows that we might also determine that the advantages of using multiple data stores within the same application (polyglot persistence) are also worth the costs of doing so.

6. Mobile Development

Mobile development continues to rapidly rise in 2012. The December 2012 write-up on the Tiobe Index states that Objective-C is likely to be the language of the year again in 2012 due to its rapid rise (third in December 2012 behind only C and Java and ahead of C++ and C#). The writers of that summary conclude about language ratings on this index, ‘In fact it seems that if you are not in the mobile phone market you are losing ground.’

Suzanne Kattau‘s post Mobile development in the year 2012 succinctly summarizes the changes in popular mobile device platforms and operating systems in 2012.

5. Scala (and Typesafe Stack 2.0 with Play and Akka)

I have highlighted Scala multiple times in these year-end review posts, but this is my highest rating of Scala because Scala has seen a tremendous year in 2012. On 23 August 2012, Cameron McKenzie asked, ‘Is Scala the new Spring framework?‘ An answer to that question might be implied by the 1 October 2012 announcement that Spring founder Rod Johnson had joined Typesafe’s Board of Directors (Johnson left SpringSource in July). Scala provides the intersection of again-trendy functional programming with widely popular and proven object-oriented programming and is part of the increasingly popular movement to languages other than Java on the JVM. It’s not difficult to see why it had a big year in 2012.

The Typesafe Blog features a post called Why Learn Scala in 2013? that begins with the statement, ‘2012 was a big year for the Scala programming language – with monumental releases, adoption by major enterprises and social sites alike and a Scala Days conference that knocked the socks off years past.’ The post then goes on to list reasons to learn Scala in 2013 with liberal references to other recent positive posts regarding Scala.

Ted Neward has predicted that in 2013 ‘Typesafe (and their Scala/Akka/Play! stack) will begin to make some serious inroads into the enterprise space, and start to give Groovy/Grails a serious run for their money.’ I am not calling Play and Akka out in this post as separate significant developments in 2012, but instead lump them together with Scala as part of justifying Scala taking the #5 spot for 2012. There is no question, however, that 2012 was a big year for Akka and Play. The year 2012 saw the release of Typesafe Stack 2.0 along with Play 2.0 and Akka 2.0.

4. Big Data

Big Data was big in 2012. AOL Government has named Big Data its Best of 2012 for the technology category. Geoff Nunberg argues that ‘‘Big Data’ Should Be The Word Of The Year.’ Interest in the statistical computing language R has (not surprisingly) risen along with the surging interest in Big Data.

3. HTML5

2012 was another big year for HTML5. Although HTML5 continued to be evangelized as a standards-friendly favorite of developers, some hard truths (such as performance versus native code) about the current state of HTML5 also became more readily obvious.

That being stated, I think HTML5 still has a very positive future ahead of it. Although it has certainly been over-hyped with emphasis on what it might one day become rather than what it is today, it would also be foolhardy to ignore it or underestimate its usefulness. Two articles that remind us of this are FT exec: HTML5 is not dead and HTML5 myth busting. The article ‘HTML5 is ready’ say creators of mobile HTML5 Facebook clone talks about attempts to prove HTML5 is ready today from a performance standpoint.

2. Security

Awareness of security holes, risks, and vulnerabilities has been increasing for the past several years largely due to high-profile incidents of lost sensitive data and new legal requirements. However, 2012 seemed to be a bigger year than most in terms of increasing awareness of security requirements and expectations in software architecture and design.

Java seemed to be particularly hard hit by bad security news in 2012. Articles and posts that provide examples of this include 1 Billion computers at risk from Java exploit, Oracle’s Java Security Woes Mount As Researchers Spot A Bug In Its Critical Bug Fix, Java Vulnerability Affects 1 Billion Plug-ins, Another Week, Another Java Security Issue Found, Oracle and Apple Struggle to Deal with Java Security Issues, and Java still has a crucial role to play—despite security risks.

The article Oracle to stop patching Java 6 in February 2013 suggests that users of Java should upgrade to Java 7 before February 2013 when Oracle will supply the last publicly available security patch to Java SE 6 outside of an Oracle support plan. Another article is called Oracle’s Java security update lacking, experts say.

1. Cloud Computing

It seemed like everybody wanted a cloud in 2012 even if they didn’t really need one. Archana Venkatraman put it this way, ‘2012 was the year cloud computing hit the mainstream.’ Steve Cerocke stated, ‘2012 will go down as the year of cloud computing.’ Other articles and posts on the biggest cloud stories of 2012 include The 10 Biggest Cloud Stories Of 2012 and Top five cloud computing news stories in 2012.

Cloud Computing is in the sweet spot many trendy technologies and approaches go through when enthusiasm is much greater than negativism. Charles Babcock‘s Cloud Computing: Best And Worst News Of 2012 is more interesting to me than many cloud-focused publications because it highlights the good and the bad of cloud computing in 2012.

Honorable Mention

I couldn’t fit everything that interested me about software development in 2012 into the Top Ten. Here are some others that barely missed my cut.


As mentioned earlier, the C programming language appears headed for #1 on the Tiobe Index for 2012. One of programming’s most senior languages is also one of its most popular. When one considers that numerous other languages are themselves built on C and when one considers that many languages strive for C-like syntax, the power and influence of C is better appreciated. C’s popularity has remained strong for years and 2012 was another very strong year for C.

Another piece of evidence arguing C’s case is the late 2012 O’Reilly publication of Ben Klemens‘s book 21st Century C: C Tips from the New School. The author discusses this book and C today in the O’Reilly post New school C.

Although I have not written C code for several years now, I’ve always had a fondness for the language. It was the language I used predominately in college (with Pascal and C++ being the other languages I used to a less degree) and I wrote the code for my electrical engineering capstone project in C. I remember (now fondly) spending almost an entire Saturday on one of my first C assignments fighting a bug to only realize that it was not working because I was using the assignment operator (=) rather than the equality operator (==). This lesson served me well as I learned other languages in terms of both what it important to differentiate and in terms of how to better debug programs even when a debugger is not readily available. I think my C experience grounded me well for later professional development with C++ and Java.

Gradle 1.x

Using an expressive programming language rather than XML or archaic make syntax to build software seems like an obviously beneficial thing to do. However, make, Ant, and Maven have continued to dominate in this area, but Groovy-based Gradle shows early signs of providing the alternative we’ve all been looking for. Gradle still has a long way to go in terms of acceptance and popularity and there are many other build systems with some of Gradle’s ideals that have failed, but Gradle did seem to capture significant attention in 2012 and can hopefully build upon that in future years. Gradle 1.0 was formally released in June 2012 and Gradle 1.3 was released in November 2012.


Among others, Scott Ambler predicted that ‘DevOps will become the new IT buzzword’ in 2012. If it is not ‘the’ buzzword of 2012, it is not for a lack of trying on the DevOps evangelists’ part. The DevOps movement continued to gain momentum in 2012. The DZone DevOps Zone sees one or more posts on the subject added each day. The only reason this did not make it into my Top Ten is that I still don’t see ‘Typical Everyday Coder’ talking about it when I am away from the blogosphere talking to in-the-trenches developers.

Amber’s concluding paragraph begins with this prediction, ‘Granted, there’s likely going to be a lot of talk and little action within most organizations due to the actual scope of DevOps, but a few years from now, we’ll look back on 2012 as the year when DevOps really started to take off.’ Only time will tell. There continue to be posts trying to explain what exactly DevOps is.

Departures of Noteworthy Development Personnel

There were some separations of key developers from their long-time organizations in 2012. As mentioned previously, Spring Framework founder Rod Johnson left VMWare/SpringSource (and ultimately ended up on the Board of Directors for Scala company Typesafe). Josh Bloch, perhaps still best known for his work at Sun on the JDK and for writing Effective Java, left Google in 2012 after working there for eight years.

Resurgence of Widely Popular but Aged Java Frameworks

Two very popular long-in-the-tooth Java-based frameworks saw a resurgence in 2012. Tomek Kaczanowski recently posted JUnit Strikes Back, in which he cites several pieces of evidence indicating a resurgence in JUnit, arguably the most commonly used testing framework in Java (and, in many ways, the inspiration for numerous other nUnit-based unit testing frameworks). Christian Grobmeier‘s recent post The new log4j 2.0 talks about many benefits of Log4j2 and how it can be used with more recently popular logging frameworks such as SLF4J and even Apache Commons Logging.

Electronic Books (E-books)

Electronic books (ebooks) are becoming widely popular in general, but also specifically within software development books. This is not surprising because e-books provide many general benefits, but also have benefits particular to software development. In particular, it is nice to be able to electronically search for terms (overcoming the poor index problem common to many printed programming books). Other advantages include the ability to have the book on laptops, mobile devices, e-readers, and other portable devices. This not only makes a particular book readily available, but makes it easy to carry many books on many different technical subjects with one on travel. It is also less likely for the electronic book to be ‘borrowed’ unknowingly by others or turn up missing.

Perhaps the biggest advantage of electronic books is cost. It is fairly well known that technical books are generally not big profit makers for publishers. However, with printing and distribution costs being a significant portion of traditional publication costs, e-books make it easier to publishers to price these books at a lower cost than the printed equivalent.

The reduced cost to the publisher for an electronic book can be passed onto the consumer. I recently took advantage of an offer from Packt Publishing to purchase a total of eight of their books as electronic books for a total price of $40. Given that a single printed programming book can cost $40 or more, this was a bargain. I have also blogged on other good deals on e-books provided by other technical publishers such as O’Reilly and Manning.

I have especially appreciated the Manning Early Access Program (MEAP). This program is only viable thanks to electronic books and allows readers to read a book as it is developed. Because technologies change so quickly, it is often helpful to get access to even portions of these books as quickly as possible.

Finally, another advantage of e-books is their ultimate disposal. In reality, they take up such a small portion of even an old-fashioned CD or DVD, that I can usually dig up a copy if I want to. However, I can remove them from my electronic devices when I no longer need them and need the space. There are no environmental or logistic concerns about their disposal. This is important because these books do tend to get outdated quickly and sometimes an outdated programming book is worse than having no book at all because it can be very misleading.

PhoneGap / Cordova

Given the popularity of mobile development and HTML5 in 2012, it’s not surprising that PhoneGap and Cordova had big years in 2011/2012. In the web versus native debate, one of the advantages of web is the portability of web apps across multiple devices. The PhoneGap/Cordova approach brings some of this benefit for writing code but maintains some of the performance advantages of running native applications.


Objective-C looks to win the Tiobe Index language of the year again in 2012. This is yet another indicator of mobile development prevalence as Objective-C’s popularity is almost exclusively tied to iPhone/iPad development, though Objective-C’s history is closely coupled with the NeXT workstations and even has been called an inspiration for Java (advertised as quoted by Patrick Naughton) instead of C++.


For several years now, it has been trendy for the ‘cool kids’ to post feedback messages on articles or blogs about Java features proclaiming that Groovy or Scala does anything covered in that blog post or article better than Java does it. Many of the ‘cool kids’ (or maybe different ‘cool kids’ with the same modus operandi) now seem to be doing the same on Scala blog posts and articles, advocating the advantages of Kotlin over Scala.

As Scala and Groovy still lag Java in terms of overall popularity and usage, Kotlin lags both Groovy and Scala in terms of adoption at this point. However, there are definitely some characteristics of Kotlin in its favor. First, the Kotlin web page describes the language as, ‘a statically typed programming language that compiles to JVM byte codes and JavaScript.’ I could definitely see how ‘statically typed’ and ‘compiles … to JavaScript’ would be endearing to developers who must write JavaScript but prefer static compilation. Andrey Breslav, Kotlin Project Lead, believes that static languages compiling to ‘typed JavaScript’ will be a major development of 2013 and he cites Dart and TypeScript as other examples of this. Being able to run on the JVM can also be an advantage, though this is no different than Groovy or Scala.

One major positive for Kotlin is its sponsor: JetBrains. It is likely that their IDE, IntelliJ IDEA, will provide elegant support for the Kotlin language. This is also a sponsor/owner with the resources (monetary and people) to improve chances for success. Because JetBrains is ‘planning to roll out a beta of Kotlin and start using it extensively in production,’ they are more likely to continue investing resources in this new language.

There was no way I could justify to myself putting Kotlin in my top ten for 2012, but once it is released for production use, it is possible that Kotlin may make another year’s Top Ten list if it is widely adopted.


Kotlin isn’t the only up-and-coming static language for the JVM; Ceylon is also relatively young in this space. I wrote about the JavaOne 2012 presentation Introduction to Ceylon and that post provides brief overview and description information.

The first milestone of Ceylon IDE (Eclipse plug-in) was released in early 2012 and was followed in March with the release of Ceylon M2 (‘Minitel’). This was followed by the Ceylon M3 (‘V2000’) release in June and Ceylon M4 (‘Analytical Engine’) in October.

The newer JVM-friendly languages with the seeming best chances of long-term viability are those with strong sponsors: Groovy has SpringSource, Scala has TypeSafe, Kotlin has JetBrains, and Ceylon has RedHat.

End of Oracle/Google Android Lawsuit

The lawsuit between Oracle and Google over Android seems to have, for the most part, concluded in 2012. There still seems to be bad blood between the two companies, but the settlement of this probably allows for continued success of the Android platform and potentially for collaboration at some future point between the two companies on Java. It will be interesting to see if Google allows its employees to submit abstracts to JavaOne 2013.

Everyone a Programmer

When HTML first started to expand across the universities and colleges in the early-to-mid 1990s, it seemed that everyone I knew was learning HTML. Most of us were ‘learning’ it by copying other peoples’ HTML source and editing it for our own use. Of course, everything then was static and fairly easy to pick up. It probably also skewed my perspective that I was majoring in electrical engineering with an emphasis in computer science and so was around people who had a tendency to adopt and use new technology. Perhaps for the first time since then, I have felt that there is an ever-growing interest in pushing everyone to learn how to program at a certain level. I don’t need to provide any supporting points for this because I can instead reference Joab Jackson‘s 2012: The year that coding became de rigueur. Not only does this post enumerate several examples of the debate about whether everyone should learn programming, but it also makes cool use of ‘de rigueur‘ in its title.


I did not include Java itself in my Top Ten in 2012. Perhaps this is an indication that I too felt that 2012 was a slow year for Java (and agree that this is not necessarily a bad thing). That being stated, Martijn Verburg has listed some ‘personal highlights of the year’ in the world of Java in 2012 in What will 2013 bring? Developers place their bets. These include the JVM’s entry into the cloud, Java/JVM community growth, OpenJDK, Java EE 7, and Mechanical Sympathy.

It’s a small thing in many ways, but I think James Gosling returning to JavaOne and throwing out t-shirts was symbolic of a strengthening resurgence among an already strong Java development community.


Java on the cloud in general had a big year in 2012. Jelastic had a particularly big year. The screen snapshot below is from an e-mail sent out by Jelastic COO Dmitry Sotnikov.

Jelastic was prominently mentioned at JavaOne 2012 multiple times. Some of these mentions were due to winning the Duke’s Choice Award for 2012. Other mentions resulted from James Gosling‘s positive review of his use of Jelastic. As I blogged on earlier, Gosling described himself as ‘a real Jelastic fan’ at the JavaOne 2012 Community Keynote.

Linux-based ARM Devices

Oracle announced release of a Linux ARM JDK in 2012. The ability to run even JavaFX on Linux ARM devices provides evidence of Oracle’s interest in supporting Linux ARM devices. Given that Oracle is well-known for investing in areas where returns are often great, it follows that perhaps Oracle sees great potential for the Linux ARM devices in the future. An interesting article that looks into this is Java 8 on ARM: Oracle’s new shot against Android?

One couldn’t go to a keynote presentation at JavaOne 2012 without hearing about one very trendy Linux ARM Device, the Rasperry Pi. Similarly, the BeagleBoard and PandaBoard have also become very popular.

Improving Job Market for Software Developers

2012 seemed to be a good year for those with careers in software development and this seems likely to continue. CNN Money ranked software developer as #9 in its Best Jobs in America story (software architect was #3). For example, Lauren Hepler has written that Software developers top 2013 job projection and cites a Forbes slides-based presentation.

Perhaps more importantly than these stories are my anecdotal observations of a surging market for software developers. I have seen an uptake in number of unsolicited employment queries from potential employers and clients. I am also seeing an increase in billboard advertising for developers, especially in areas of the United States with high concentrations of software development. This improving job market might be one of many reasons for increasing interest in programming in general.

Other Resources

There are other posts of potential interest. Katherine Slattery’s Takeaways from the Top Development News Stories of 2012 talks about the Node.js ‘hype cycle,’ open source hardware, native apps versus HTML5 apps, and the ”learn to code’ craze.’

Ted Neward‘s annual predictions (for 2013 in this case) and review of his prior year (2012 in this) predictions is an interesting read.


2012 was another big year in software development across many different areas and types of development. Many of the themes discussed in this post overlap and are somehow associated with mobile development, cloud computing, and greater availability of data.
