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.

Mocks are mocking at you?

Apr 13, 2016

Enjoy the following series of interviews with the speakers, top-notch software crafters from across Europe, joining  I T.A.K.E Unconference, Bucharest, 19-20 May. Discover the lessons learned and what drives them to challenge the known path in their field. 

 

Andreas Leidig, Developer & Agile Mentor MsgGillardon AG, and Robin Danziger, Software Developer, will join I T.A.K.E Unconference 2016 as speakers. They will share in their talk more about mocks and prototypical library for solving this problem in JavaScript: chadojs.

#1. SHARE TOP 5 THINGS YOU DID THAT HELPED YOU GROW & BECOME THE PROFESSIONAL YOU ARE TODAY

Robin:

  • Regular participant and speaker at conferences & local user groups
  • Coaching teams and organizing internal meetups about software development
  • Working with different teams and companies (I’m a freelancer)
  • Ask professionals how they would solve a problem
  • Try to read the whole internet 😉

Andreas:

  • Initiating a conference (SoCraTes)
  • Visiting and speaking at conferences
  • Listening and questioning my own views
  • Working with different teams (during my previous job)
  • Thinking outside the box

 

#2. What challenges will the participants find solutions to during your session at I T.A.K.E Unconference 2016?

Participants will learn about the possible pitfalls and gaps when using mock objects blindly. They will understand that this may lead to decreased safety for refactoring and this weakend trust initiates the need for creating more and more integration tests.
They will see the underlying principles and learn about ways and techniques to escape this trap.

 

3. What else would you like to share with participants

Robin:
I like to talk about different software development approaches. How can we use and maintain software tests from specifications and end-to-end-tests to unit-tests. And I would like to know how other teams share their knowledge and improve the collaboration inside the team.

Andreas:
Don’t be shy. Open your ears and eyes. Listen and ask.

Rebecca Wirfs-Brock: Maintaining Your Code Clint Eastwood Style 

Dec 01, 2016

Rebecca Wirfs-Brock is the object design pioneer who invented the set of design practices known as Responsibility-Driven Design (RDD), the first behavioral approach to object design. She is the lead author of two software design books and design columnist for IEEE Software. By accident, she started the x-Driven Design meme (TDD, DDD, BDD…). Although best known for software design, she is has a passion simply expressing complex requirements and effectively communicating software architecture.

Rebecca shared with the audience how to maintain your code in the keynote address from the first edition of I T.A.K.E Unconference. Watch below her remarks!

Crafted Design with Sandro Mancuso

Feb 19, 2015

Sandro Mancuso, the initiator of the London Software Craftsmanship Community, wondered how to structure the code so that it reveals not only the architecture but also its features. In this talk, he shows how to better organize namespaces and domain entities, something he called Interaction Driven Design.

Enjoy his presentation @ I T.A.K.E. Unconference 2014 edition. Curious about 2015 edition?
