Covariance and contra variance. Say what ?!

May 09, 2017 by Madalina Botez in  Announcements

Enjoy the following series of interviews with the speakers, top-notch software crafters from across Europe, joining  I T.A.K.E Unconference, Bucharest, 11-12 May. Discover the lessons learned and what drives them to challenge the known path in their field.

Alin Pandichi, Software Developer at MozaicLabs and facilitator of the monthly Coding Dojo meeting that is part of the largerBucharest Agile Sofware Meetup Group, will share during his talk at I T.A.K.E Unconference more about Covariance and contravariance.

 

#1. Please share with us 5 things you did that helped you grow & become the professional you are today

I’ll answer this with a little bit of story telling about how I became a software developer. The first two things that helped me were attending the computer science oriented high school and college. There, I learned the basics of computers and programming languages. I also noticed how effortlessly I was solving CS related problems, so maybe I was onto something.

Number three: I got my first job straight out of college, developing a Swing rich client application saving data with JPA. This put me face to face with real world problems. I was faced with the fact that continuous learning is a must in this industry.

Therefore, number four on the list is learning. For the first few couple of years, I kept devouring every Java-related article I could find on DZone. With each one, I found out something new: a useful tool, a Linux terminal command, a development methodology, etc.

Last, but not least, is getting involved with local software development communities. I started attending meetups such as The Bucharest Agile Software Meetup Group and the Bucharest Java User Group. Gradually, I became an active member of both, giving a helping hand in organizing their events. On top of that, I also got involved in the wider community of Global Day of Coderetreat. My talk at I TAKE 2017 is one of the occasional opportunities I get to share what I know.

 

#2. What challenges will the participants find solutions to during your session at I T.A.K.E Unconference 2017?

They will find it easier to understand the concepts of covariance and contravariance, and how they are applied in the world of programming. In my experience, it was very easy to forget what these two words meant. Not anymore.

 

#3. Recommend for the participants 3 sources you find inspiration from and would help them better understand you

I dream big, so my biggest source of inspiration is science fiction. My first serious SF encounter was with Frank Herbert’s Dune series. Out of the contemporary authors, I enjoy Neil Gaiman’s work very much.

Whenever I get a chance, I tune into Nick Francis’ podcast called Quiet Music. It is a blend of low beat music of various genres: electronic, jazz, instrumental, folk, light rock, and so on.

Cinema is one of my other hobbies. I am very much interested in following every film festival happening in Bucharest. Also, the Romanian cinema of the past two decades has offered many gems so far, and it continues to do so.

#1. Please share with us 5 things you did that helped you grow & become the professional you are today

 

It all started when I was posting answers for the Stackoverflow community and the reputation started to grow over 100k. I realized that being a professional is a constant effort and never ending learning of new cool stuff. To be up to speed you need to constantly shift to emerging technologies. You see the merit when your answer voted and uncounted millions of people also learn.
We need to be open-minded and have a mentor around us to grow. As you might not have a mentor close to you in person, you can leverage online communities such as Stackoverflow, a community that helps you grow. It helped me.
Then when you take it offline and be supportive & active in local communities, participate in Startup Weekends, community projects you believe in – you will be able to work on fun stuff. Also being part of an IT company such as REEA, it helped me become a professional by all the great startup projects I had to work on, the colleagues, the clients, and also the conference participations.
In 2016, I was nominated and accepted into the Google Developers Experts program. Having my exemplary work recognized by the greatest company in the IT industry and pointing me as an expert and outstanding professional, it gives me new goals to achieve even more.

#2. What challenges will the participants find solutions to during your session at I T.A.K.E Unconference 2017?

Nowadays there are dozens of options to choose how you architect your project for next level of data analytics. We will cover how Google BigQuery helps to solve the petabyte scale data warehousing, and ability to write complex queries for your dashboards.

#3. Recommend for the participants 3 sources you find inspiration from and would help them better understand you

My inspiration inbox is Feedly, there I consume all sorts of content I really enjoy reading: High Scalability, Percona Blogs, Codrops, Medium, SIMB.

Show your coding skills while competing with peers like you

May 14, 2015
Do you know how to test systems? Can you point coding issues? Are you open to learning from other people? And, best of all, can you safely clean up existing code and improve its design? These are all core developer skills nowadays, and you’ll greatly benefit from mastering them. Here’s just one more opportunity to do so during I T.A.K.E. Unconference – The Programming Contest. We think you’re going to enjoy it.

 

Take a set of challenges that will put your skills to the test, overcome them and get the most points to win the contest. Oh, we almost forgot: those getting the most points win gadgets like a drone or an iPad. They are still small rewards compared to the learning, but we’re sure they help :).

How the Programming Contest works?

Well, this is simple. We try to automate the process as much as possible. For the moment the instructions are as simple as:
  • Register for THE contest on May 28
  • Solve the challenges
  • Submit the solutions until May 29, 2 pm
Really cool: you can use ANY of the following programming languages: Java, C#, PHP, C++.

Who will review your code?

The Jury is built of Software Craftsman Fellows from Europe – names soon to be announced. They will grade each challenge you took. There will be just a few challenges, and taking all of them may lead you to the highest score. So the more you solve the closer to win.

Compete with passionate coders at I T.A.K.E. Unconference

Join the crew, compete with developers like you, gain recognition and take the drone home, offered by Mozaic Works. Or the iPad offered by Accenture.
Don’t miss the Programming Contest as well as many other hands-on sessions at I T.A.K.E. Unconference happening in Bucharest on 28-29 May 2015.
