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

Starting my own business, leaving the comfort of a company where you get a certain sense of security by deriving a regular salary, and having to deal with the hidden iceberg of new skills  I had to learn but hadn’t realized I didn’t even know about.
Joining my first start up, which wasn’t the same as a usual job, nor with the degree of control of just running my own business, was a great learning experience on how to deal with uncertainty while still aiming to provide a measure of direction.
Realizing that, as a developer, your job is not to deliver code. Your job is to keep the user happy, and delivering code is only a part of that. It requires a mental shift from the technology-focused mentality one tends to have as an engineer.
Working with distributed teams, and learning to adapt to the different work and communication styles of people from different countries, has made a huge difference in adaptability, and has taught me to not assume the message is always getting across.
Going through several technology trends and epochs, seeing language and platform flame wars rage and abate, trying a bit of everything, helps come to grips with the idea that a language or a platform is just a tool, and it’s what you do with it that matters.

 

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

The idea that being unable to modify your data can bring more flexibility is unintuitive.
However, the bigger our codebases grow, the harder it becomes to find out if a refactoring process, or even a seemingly small change, will have a negative impact. Test suites can reduce this uncertainty, but normally only inform us of a problem *after* we’ve made a change.  There’s usually no way to know, in advance, how time consuming the side effects of a modification will be.
A shift in mentality towards data immutability, whatever the language we are using, will help structure the code and functionality in a way that makes it easier to grow and change down the road.

 

#3. What else would you like to share with participants ?

I assemble and lead project-specific teams to tackle challenges involving interaction design, data and open source. I’ve been working on software for over 20 years, across multiple industries – from desktop tools, to banking and financial institutions, to healthcare, to gaming.
I usually work with distributed teams, as I’d rather take the expertise where I find it than expect it to be around the corner, and it leads to interesting, varied teams with different perspectives.
A voracious reader, of both technical and non-technical books, it would be strange to find me without one or two tomes in progress.  This extends to platforms and languages – I very much enjoy kicking the tires on both, always looking for something new to learn.

Mutation testing

Apr 28, 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. 

Nicolas Fränkel, Software Architect with 15 years of experience in a wide range of contexts, University teacher, experienced trainer and book author will join as speaker I T.A.K.E Unconference 2016. In his talk, he will explain how Code Coverage is computed and what its inherent flaw is. Afterwards, he will describe how Mutation Testing works and how it helps pointing out code that is tested but leave out corner cases.

#1. SHARE TOP 3 THINGS YOU DID THAT HELPED YOU GROW & BECOME THE PROFESSIONAL YOU ARE TODAY

  • I chose to become a programmer, because during my architectural studies, there was a course on POV-Ray, a ray-tracing software where scenes are described with a language
  • I now avoid not well-understood bash commands after trying to execute a find with exec rm command on a production server and starting deleting the server’s filesystem
  • I value knowledge sharing since I started teaching a very long time ago

#2. WHAT CHALLENGES WILL THE PARTICIPANTS FIND SOLUTIONS TO DURING YOUR SESSIONS @ I T.A.K.E UNCONFERENCE 2016?

During my talk, Mutation testing to the rescue of your tests, ​I will not provide a solution but challenge attendees beliefs. Code coverage is the most talked about metric when we speak about quality, but it​s only quality is that it’s easy to compute. In my code, I will show it means nothing, and provide you something more reliable to work with.

#3. WHAT ELSE WOULD YOU LIKE TO SHARE WITH PARTICIPANTS?

​I’m a Java geek, through and through, but also ski in winter, run, play squash, sketch nudes, write books, and am currently learning Russian and Kotlin.​

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

 

There might be a fortunate series of events, which fit nicely with my personality and abilities.

One of the things that helped me a great deal, was the fact that I changed the contexts and projects often. Even if I worked for the same company and the same technologies for about 10 years, I have changed the projects, the clients and my role at least once in two years. It wasn’t something that I had planned, but I always wanted to learn and experience new things.

Change is always challenging and creates opportunity for learning and for professional growth.

Another important thing for me, I think it was the fact that I always look for professional models. First, I discovered Uncle Bob, then there were Martin Fowler, J.B. Rainsberger, Roy Osherove, Kent Beck, Juval Lowe, Jurgen Appelo, Richard Campbel, and many others (I remember having a slide with some of these guy’s pictures in one of my first talks I’ve given at a conference ☺ ). Reading their books and articles, and then trying to apply their ideas in my day to day work, inspired and helped me.

Attending to training and conferences is another important thing. The TDD workshop with J.B. Rainsberger, which I attended back in 2010 was a few years jump ahead in my career. After, there were many other high-quality training I had the opportunity to attend, like the IDesign Master Class with Richard Campbel, a workshop with Dan North, or a Requirements course with Kay and Tom Gilb.

Coding just to practice is another thing that makes a difference. I learned this at the Code Retreats and I’ve kept this good habit. From time to time I take a few hours and I just write code with the purpose of learning or practicing. It always pays back.

 

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

 

In large enterprise applications, there is always the challenge of decomposing the system. From performance considerations we may end up loading all the services in one or two processes, ending up with a monolith, which doesn’t scale and it is costly to maintain. At the other end, we have one process for each service resulting in too many inter-process call hops to handle one user request, which is bad for performance and it may be costly to maintain.

I’ll show a way, which I’ve applied in some projects I’ve architected, on how to separate this communication concern from implementing the business functionality.

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

  • My blog of course ☺ onCodeDesign.com . There, it is more about me and my thoughts
  • .NET Rocks (https://www.dotnetrocks.com/) is a podcast I recommend especially to .NET developers, and also to any geeks
  • As a hobby, I recommend learning and playing GO. Even if it a time-consuming game, it is a very good exercise for the mind.
