Abstract of the Talk – Hands on overview of Kotlin programming language

This session will cover an introduction to the Kotlin programming language and lots of hands on examples of how Kotlin helps write concise, safe and expressive code. It will also refer to how naturally Kotlin interoperates with existing Java libraries and frameworks and how Java and Kotlin frameworks and libraries can work smoothly with each other. The session will focus on core programming rather than any specific areas such as Android or Web or other specialised types of programming.

The audience is presumed to be reasonably aware of Java programming.

About Kotlin

Kotlin is one of the hottest new programming languages in recent times. One of the fast growing languages of 2017, it has the potential to become the preferred language for Android app development, for backend development on the JVM, and even has to potential for use in the frontend (browser). It is a concise and modern language with many advanced features like null safety, extension functions, infix notation. It has full Java compatibility (so you can use all Java libraries without any significant impedence mismatch), good IDE support (Android Studio, and IntelliJ), improves code readability, reusability, and development speed.

Kotlin has been announced as an official Android Development language by Google, and it has been adopted by a number of high-profile companies like Amazon Web Services, Pinterest, Coursera, Netflix, Uber, Square, Trello, Basecamp, and others.

Opportunities in Cleantech (IT/analytics/internet-of-things) – with Infuse Ventures (Cleantech VC)

  • Date: Fri, 18 Jul 5:30pm – 7:30pm
  • Location: 5th Floor, A-Wing, MCCIA, ICC Towers, SB Road

Infuse Ventures, India’s largest early-stage cleantech VC fund, in partnership with MCCIA, TiE-Pune and POCC, would like to invite you for a unique event on Friday, 18 July 2014 at the MCCIA Trade Tower, Pune. The event will focus on the ‘breadth of entrepreneurial opportunities in cleantech’. While we will outline the ever-expanding boundaries of cleantech, we will also specifically focus on ‘the role of IT, data analytics and internet of things (IoT) in cleantech’.

Traditionally, the cleantech sector has been equated with extensive R&D, technology-heavy and project businesses that require huge capital investment. However, things have been changing. In the west, many different businesses have come up in the clean technology space that rely heavily on data capture, data sharing and analytics to enable energy and resource efficiency and promote sustainability in homes and across commercial and industrial set-ups. The importance of data and the ability to learn and act based on it is changing the paradigm of looking at the clean technology space.

We hope this session will throw open a new area of potential growth for entrepreneurs who are already in either the cleantech space or IT, data analytics and IoT space. Additionally, we hope this session will help you take a fresh look at your (or your company’s) current capabilities from a fast-evolving cleantech perspective. We believe that the cleantech opportunity is as immense as the web itself, since it increasingly touches every aspect of how we live, work and play.

At the event, you will also get an opportunity to listen to a few exemplary entrepreneurs who re-purposed or applied their non-cleantech capabilities to the cleantech field.

The event is free and open to everyone. No registration is necessary. The seating is on a first-come-first-seated basis. The Infuse team will be on hand on the following day, 19 July, for 1-on-1 meetings with any current or aspiring cleantech entrepreneurs.

Fees and Registration

Pune Robotics Meetup: Robots/Raspberry Pi/Arduino Home Projects Demo

  • Date: Sat, 19 Jul 11:00am – 2:00pm
  • Location: Robofun, 205, Vision Galleria, Opp G-Mart, Pimple Saudagar

Bring your own Robot or any other project (on Raspberry Pi/ Arduino platforms) you might have developed and share your story with the group!!

This meet-up is for people who have built something interesting at home and are interested in displaying/ demo their product to a smaller audience first before going big for a quick and constructive feedback and share their experience/ knowledge with others who share similar interest.

I believe kids who are pursuing or want to pursue Robotics as their hobby can also benefit from such opportunities and so they are welcome to join too along with heir parents!!

About the Pune Robotics Meetup

This group is about giving a platform to all robotic enthusiasts and jointly find ways to promote this hobby across Pune. We often receive enquiries from parents about how to get their children started in robotics. ‘Does my child have to know a lot about programming in order to engage in robotics?’ ‘My child is only 6 years old. Is it too early for him to start doing robotics?’ The answer to these questions is ‘NO’. In fact, the appeal of robotics lies precisely in the fact that it is a sport for everyone, regardless of experience and age. One can find like-minded people across the world, ranging from young hobbyist in primary school extra-curriculum clubs to professional researchers in NASA robotics research lab. Perhaps, to many children, the world of robotics may seem to be complicated and mysterious. After all, the daily newspaper is filled with breaking discoveries in the world of robotics. Yet, robotics, at fundamental level, can be very simple. Do not hesitate to take your very first step into robotics—for it promises a journey of unending fun and discoveries!

Fees and Registration

Event Report of @GhoseB’s 2-Day Clojure workshop – by @SwaroopCH

Event Reports, , , , ,

Last weekend BG aka @ghoseb conducted a 2-day free Clojure workshop – which was “sold out” and many people had to be disappointed.

Swaroop C H (who is famous for many things, one of which is A Byte of Python a free online book that has helped many people learn Python), was apparently in town, and attended the two sessions.

He has written a detailed and insightful event report. Here is his report of day 1 and report of day 2.

BG has promised to conduct another workshop for the people who couldn’t be accommodated in the first one due to space constraints.

Event Report: IndicThreads Java Conference 2011

Event Report, , ,

(This article about the IndicThreads Java Conference 2011 was written by Abhay Bakshi for DZone. It has been re-published here with permission for the benefit of PuneTech readers.)

Attending a conference (probably as renowned and as recognized as the Java conference by IndicThreads) adds to your muscle – Period. By the way, I have picked up from the same thread — same tone and similar spirit — from March 2011. IndicThreads held the Q11 conference then, which I had a chance to attend and then write a short report on for DZone. If you attended IndicThreads conferences before, your feedback is also welcome — through your blogs or through places like this report hosting page.

Now, you may ask – How Was the Environment This Time?

First and foremost, I would like to say this — you could feel the thought process from Harshad Oak (Owner – IndicThreads – Conference Organizer) all throughout the conference. When I attended the conference sessions, I could see that one presentation simply led to another one. And somehow I could also relate this fact to the earlier Q11 conference; and could see the passion that Harshad has when he arranges these events.

Just as a side note – Harshad is the first Java champion in India and he continues to serve the IT community. He is ably supported by his wife Sangeeta Oak in these endeavors. This young couple gives a lot of attention to detail for the events!

The Conference Agenda in short

The conference agenda included the following topics (Friday/Saturday — Dec 02/03):

  • The Java Report (Harshad Oak)
  • Scalability Considerations (Yogesh Deshpande)
  • PaaSing a Java EE 6 Application (Kshitiz Saxena)
  • Solr as your Search and Suggest Engine (Karan Nangru)
  • Testing Concurrent Java Programs (Sameer Arora)
  • Scala Collections: Expressivity and Brevity upgrade from Java (Dhananjay Nene)
  • REST Style Web Services – Google Protocol Buffers (Prasad Nirantar)
  • Java EE 7 Platform: Developing for the Cloud (Kshitiz Saxena – yes again! He has awesome topic coverage.)
  • Building Massively Scalable Applications with Akka (Vikas Hazrati)
  • Simplifying builds with Gradle (Saager Mhatre)
  • Using Scala for Building DSLs (Abhijit Sharma)

The presentation slides are hosted at http://j11.indicthreads.com/slides

My Thoughts on the Agenda

On the first day of the conference, I noticed that there are 7 sessions to attend on Friday and 4 more sessions on Saturday. Frankly, I thought there was some kind of mismatch in arranging these sessions. But my opinion changed as the conference went on from Friday into Saturday. The next day was intentionally kept lighter. As an attendee, I now think that your mind probably absorbs and retains more information during the initial parts of a conference. I believe that IndicThreads is getting better overall conference after conference.

What I Wanted to Get from Each Session

I planned on getting 3 things from the sessions (that was my ROI!) — first, how the knowledge earned will apply towards the business domain at my work place; second, my personal interactions with the speaker(s) from networking perspectives; and third, how I can help Harshad and his team and provide helpful feedback. Even with events like NFJS, TSSS in USA, I always received and offered my best to organizers Jay Zimmerman, Floyd Marinescu et al.

I should also mention, I still remember Rick Ross’ keynote speech at TSSS and how it was inspirational to many of us there. Point is that industry leaders like Harshad, Rick, Floyd (and of course some more) are doing everything to lead developers all across the world to be better IT professionals. Sometimes they pay from their own pockets to see results.

The Actual Sessions

I am not going to cover all the details from all the talks, well, it’s not possible. The slides are available for entire content.

The Java Report

In the keynote speech, Harshad mentioned that things moved very rapidly after Sun was purchased by Oracle. He later encouraged participants to have a look at topics such as Java EE 6 Web Profile, Java FX 2.0 (all Java), Java EE 7 and a few more. Harshad raised a point – do you as a Java expert look the same “sexy” today as you did when Java started? The answer is “less sexy”. He also said that Java ME was not offering many new things for quite a while now.

Scalability Considerations

Yogesh covered Vertical Scaling and Horizontal Scaling, and principles behind both techniques. He backed up his presentation with a helpful case study.

PaaSing a Java EE 6 Application

Kshitiz works at Sun/Oracle for last 10 years. He explained PaaS in simpler terms. It was very important to keep things simple. The speech was well accepted by the audience. Just as I was putting this article together, I saw that Javalobby had published a fresh article on PaaS 2.0 — it looks quite relevant to our discussion.

Solr as Your Search and Suggest Engine

It was very good to learn from Karan about Embedded Solr Server versus Commons Http Solr Server, and the various “search” and “suggestion” cases. Karan is quite passionate about Solr.

Testing Concurrent Java Programs

I don’t develop as much concurrent Java code at work as I do some other pieces; but learning from Sameer clicked a few ideas in my mind for a business case that we have at work. We (AEGIS) do some case executions in our workflow, and ideas from concurrency can be applied to what we do. By the way, for the intense session that we had with Sameer, fortunately, there was a coffee break after the session. Hats off to Sameer for how much he knows about this topic.

Scala Collections – Expressivity and Brevity upgrade from Java

Although Dhananjay knew a lot, he was addressing a very specific topic “Collections”. To me, the topic could have been broader (or be split in two sessions). Scala is a powerful language and initial learning curve looks longer for a beginner. I should mention that Dhananjay preferred IntelliJ for Scala-based development — rightfully so.

REST Style Web Services – Google Protocol Buffers

Prasad (speaker) has a background from Akron, Ohio (M.S.). He compared content negotiation techniques (JSON, XML, and Portable Binary Content) with focus on Google Protocol Buffers. His comparison of Google Protocol Buffers with Apache Avro was very apt.

Java EE 7 Platform: Developing for the Cloud

Kshitiz explained the terms IaaS, PaaS and SaaS. There are vendors other than Sun that offer PaaS support — but standards are lacking. He explained Java EE 7 focus on PaaS – Elasticity which has progressed from single node implementation to multi-node multi-instance clustering to SLA driven Elasticity. Refer the slides for more details.

Building Massively Scalable Applications with Akka

Vikas writes for InfoQ. He said that if you wanted to learn Akka, then you needed to keep in mind that Akka was designed to make developer’s life easier by addressing concurrency, scalability and fault-tolerance in applications. The founder of Akka is Jonas Boner, and I find Jonas’ article on Akka hosted by Javalobby at this page. As per Vikas, Akka is good for event-based systems, whereas Hadoop for batch-based systems.

Simplifying Builds (Build Scripts) with Gradle

An excellent slide presentation and visual illustrations by Saager. He corrected the name of the topic to “Simplifying build scripts..”. He compared Gradle with Ant and Maven, and mentioned that Gradle describes builds with only as much text as is absolutely necessary.

Using Scala for Building DSLs

This was the only session where there were no questions from the audience! From Abhijit’s (speaker) angle, it was a bit uncomfortable feeling; but I later mentioned to him that the presentation was so straight-forward (note – not an easy compilation) and neatly arranged, the questions were answered even before they were asked. I recommend – just download the presentation, and you will get to see what I mean. Good to learn about Scala in this domain.

Every session was little over an hour. And all speakers covered their sessions very well.

Past Reviews of IndicThreads Conference on Java

Some of the celebrity authors and speakers like Arun Gupta and Vikas Hazrati have reviewed their prior Java IndicThreads conference experiences by writing articles on their respective blogs (you may access the reviews: Arun, Vikas). It is rewarding to learn from such experts in the field.

Lastly, about the Food and Quizzes and Prizes!

I believe, Sangeeta made awesome choices for food at lunch and the breaks! As well as, she put up short quizzes and announced prizes in different categories. IndicThreads have maintained the “Green” theme and I won a prize in that category.

My Top Three Take-away Points

My top three take away points from J11 are – rejuvenating yourself by looking at technical topics from speakers’/attendees’ eyes and adding to your knowledge, networking with experts so that you can offer your best and receive the best from them, and just knowing where the Java industry stands today.

Conclusion

There was an “Unconference” session, where everybody who participated voiced a need for the Java groups in the city to come together. I get a feel that awareness in the industry about such conferences is increasing, and demand for such speakers and quality offered by these conferences is going to increase in few more short years.

Harshad encourages local speakers to come out and respond to the RFPs (and participate). For those who only want to attend can also win a FREE pass to the conference! All in all, it was worth attending the Java conference by IndicThreads.

Event Report: Java 7 Launch Event in Pune

Event Report, Featured, , ,

(This article by guest writer Amit Naik, an architect at BMC Software, Pune, is a report of the Java 7 Launch event that happened in Pune last weekend.)

Harshad Oak started things off by pointing out that Java has a bit of ups & downs in the past couple of years. Hopefully Java 7 will reverse the trend. He also encouraged people to join the Pune Java User Group to stay connected with other Java users in Pune.

Then, we moved on to the main speaker: Chuk-Munn Lee (chuk-munn.lee@oracle.com). Fun fact – Chuk-Munn is a fan of Futurama and called out the fact that he is wearing a “Bender the Robot” T-Shirt.

These are the highlights of Chuk-Munn’s presentation:

The last Major release of Java – Java 6 was in 2006-7 and no major releases since then. JavaSE7 has a lot of gestation period. The big release of 7 is now broken down into 2 incremental releases Java 7 and Java 8 to get something out of the door faster and make it more manageable.

Reading is more important than writing for Programming Languages. Programs should be a Joy to read. Counter example PERL a Write-Only Language, or Looks Same Before and After AES Encryption. A Camel is a horse designed by committee. Very difficult to read and maintain. So very difficult to collaborate in large teams or large codebases where readability is important. This is where Java shines but it has sometimes got too much boilerplate code needed.

Applications in the commercial world compete on the basis of features – same should not apply to programming languages. In languages you want fewer features but they should work consistently. So it is difficult to add new features to Java consistently.

The main features new in Java 7 can be grouped into these categories:

Small Language Changes (Project Coin)

  • Binary Literals with underscores for clarity
  • Strings in Switch statements
  • Inferring types with <>
  • Varargs Warnings @SafeVarargs fixes problem of Heap Pollutions JLSv3 4.12.2.1
  • Multi-Catch – very useful in reducing boilerplate code if used properly!
  • Copying Streams – try-with-resources

NIO2

  • NIO2 (JSR -203) java.io.File does not work consistently across platforms, missing basic operations like copy, move, etc.
  • Path Class (Async I/O)
  • Features – Filesystem and Filestore support
  • Symlink support
  • Basic File operations
  • File attributes and Permissions support enhanced
  • Other interesting features
    • Watch files directories

Invokedynamic

Java may or may not be the first choice of everybody but JVM is massively popular and many, many languages are adopting it. The VM spec is from 1997 – fairly generic and not specifically wired to Java except for the 4 key bytecode instructions – invokespecial (constructor invocation), invokestatic (statics), invokeinterface (interface), invokevirtual (methods)

Java 7 is introducing a new instruction for Java 7 invokedynamic that will allow for late binding in languages such as JavaScript to be natively supported on the JVM.

Other Features

  • New Fork-Join framework
    • ForkJoinPool and ForkJoinTask along with fork keyword to natively support fork-join semantics
      natively on the VM
  • New decorators for Swing – Jlayer and LayerUI
  • Infiniband support – using a sockets direct protocol (SDP) over the wire
  • Utility methods for java.util.Objects

That was end of the main presentation.

Time for Audience Q/A

(All Questions/Answers paraphrased to best of my recollection)

  • Java 7 seems like an underwhelming release. Why?
    • There was a very long gap between Java 6 and Java 7 because of the inability to move things thru to conclusions fast enough in the JCP. All the big features were not done yet so it would have taken a lot longer to get everything finished. Oracle polled the community and the result was two releases – one with all the finished features and one with all the big features -Java 8- to follow shortly thereafter.
  • Will Oracle make Java more “restrictive” in terms of licensing etc.?, What is Oracle’s commitment to Java?
    • A very large part of Oracle’s internal codebase is on Java so Oracle has excellent commitment to Java and will move it forward Will it make it more restrictive license wise – this question has been comin up over the years and the answer is always NO. Most of Java is under a GPL-like license anyway so cannot be really made more restrictive.
  • With the departure of Apache Software Foundation from the JCP and the Lawsuit over Android against Goolge what is the future of JCP and the Java community?
    • Cannot comment on the lawsuit. If the situation with the ASF worries you personally then you should consult a lawyer. I (Chuk-Munn) ask myself this question – does it personally affect me in any manner? If not then I do not worry about it.
  • Is the support for dynamic languages increasing or decreasing with Java 7?
    • Increasing with the introduction of invokedynamic etc.

The PPT that was used by Chuk-Munn Lee is available from here (see attachment at the end of that page)
