Nikolay Ryzhkov

RailsClub

Biggest Russian Ruby on Rails event

Health Samurai CTO, Saint Petersburg Ruby & Clojure, Piter-united communitites activist, speaker of RailsClub 2016.

At the conference, Nikolay talked about functional paradigm for Ruby coders.

After the conference, we've managed to talk with Nikolay.

How have you became a Ruby developer? 

I came to coding late, when I was 25 years old, from radiopharmacy. For several years I was coding on php, java, C #. And then there was a project on ruby on rails, it was about 8-9 years ago.

What are you working on right now? 

Developing a medical platform. Also, our team in engaged in developing international standard called FHIR and open source tools for it. 

What's last interesting thing that you have learned? 

ClojureScript * React is an interesting unite, that allows you to develop frontend easily and comfy.

In your opinion, how will Ruby and Rails develop in the nearest future? 

RoR is a tool for fast web development, and it is good at it. I don't think that it's vector will change somehow. A lot of different good and helpful features will be created.

What's the main problem that RoR community faces at the moment? 

That main Ruby activists migrate to other technologies, like rust, go, erlang, clojure and so on.

What is missing in Rails, in your opinion?

Simplicity and elegance are present outside, but not inside.

What’s your favorite programming language besides Ruby? 

Clojure, definitely. For me, the transition from ruby ​​to clojure can be comparate as java to ruby. Clojure is a functional language that allows to solve most of my tasks easier and more rigorous. Next comes a long list: dynamism and metaprogramming, interactive development, support for competitiveness, the ability to use java libraries, etc.

What technology, in your opinion, will be the most promising in the near future?

A big explosion in the frontend, I think there will still be a lot of discoveries. The containers grow (docker, rkt). Distributed and reactive systems (databases, processing of large data streams, queues, consensus). Renaissance of functional programming.

What is Open Source for you? In which projects are you involved and why?

We put in the open source a significant part of our work related to the FHIR standard (fhirbase, fhir.js etc). In general, if something can be opened, we open it. Because practical all our stack is built on open solutions, and we are part of this ecosystem.

What’s your favorite books about programming? 

  • Structure & Interpretation of Computer Programs (H. Abbelson)
  • Domain Drive Design (E. Evans)
  • The Design of Design (F. Brooks)

What advice would you give to developers who want to achieve great success?

Never stop at what has been achieved. If in a year your professional worldview has not turned 180 degrees, then it's over. Speak / organize for meetings and conferences, do not neglect live communication with colleagues - it gives a serious motivation that you will not get from books and the Internet.

Who you wanted to became in childhood?

I don't remember anymore.

Not tired of programming?

No, it's only beginning.

What would you do if you had 2 months of free paid time?

I would read books on the beach, I think about life. At leisure, I would rewrite a couple of open-source projects. Generally a good idea.

RailsClub conference on which we managed to communicate with Nikolay will take place this year in Moscow 23th of September.

A software engineer with over 10 years of experience, working as Tech Lead at Icelab. Active OSS contributor and maintainer of various projects for over 5 years. Former DataMapper core team member, creator of the popular Virtus gem, lead developer of Ruby Object Mapper project, and dryrb core developer.

On the RailsClub 2017, we've managed to talk with Piotr about his work, dry stack and future of IT.

Please, tell me about yourself. Where do you work? What do you do?

I’m a software developer from Poland. I worked mainly with web apps for last 14 years. I’ve graduated as bachelor in computer science. I’ve studied a bunch of languages and found a job as PHP developer, then I’ve switched to Ruby in 2007. That was my life for almost 11 years. Mostly doing Ruby and worked a little bit with functional languages for few months and now I’m back with Ruby as my main language.

Is it your first time in Russia? How do you like it? How do you like RailsClub?

It’s my first time in Russia. I really like Moscow, it’s really nice city. I like that it’s big. There’s a lot of space. I live in Krakow, so, it has crowded, narrow streets, lots of buildings close to each other. We’ve got nice weather in Moscow! And it’s always raining in Krakow. I really like. People are nice, the conference is awesome. I’m really enjoying it. I also like that people have a lot of questions. I’ve been talking for less than three hours with like 20+ people. That’s really encouraging for me.

Can you give us keynotes from your report?

I’ve talked about the project with which I was working since 2011. I’m basically trying to build a new set of tools to work with databases in Ruby. To shift people to alternative approach, not a typical object-oriented approach, when it comes to working with databases. The talk was about upcoming version 3.0, which is expected to be realized in October. The main thing is to show that this library, despite it is much more advanced than existing solutions, it’s finally as easy to use as this existing solutions.

As far as I understand, your library is designed to replace Active Record. What is main advantage and disadvantage of your product?

The main advantage that it is much more flexible than active record because you don’t have to module your app domain in the same way as your module database tables. You can have different sets of attributes for certain modules and certain modules don’t have to be one-to-one mapping between the tables and their representation in Ruby. This means that when your application growing and you starting to see more and more domain specific concepts you will be able to module them just by using API that we have. It’s also easier to make changes in databases because you have chainset API that we introduced recently. We can use it transfer data from representation that your application receives into a structure that is compatible with your database. We don’t have it in Active Record - concept of data transformation. And, second advantage - it’s kinda lightweight, because the data structures that we load, the objects, that we load, they are smaller than Active Record objects. They take less memory and they are faster. As a result , Rom is faster, it can work with different databases. people are using Rom with data that they pull from YAMA files or csv files or HTTP API and then they combine these data and with what they have in their database, maybe store in their database after some transformation. It’s just much more flexible and support.
Disadvantages are mostly related to the fact that it’s still young project. First few years of my work was mostly experimentation and project started at 2013 and 1.0 version was released in November. That’s not a lot for open source project. 3 years for open source is like 3 months in case for a normal project. As a result, we’re lacking the documentation, which is in big priority right now, our community is much smaller, we use less 3rd party tools and extensions than in case of Active Record. We don’t have 3rd party solutions for stuff like file uploads or authorization.  We are on our own in a lot of common cases. That’s the biggest disadvantage. If you don’t feel like build a plugin for a file upload, it’s not gonna be good fit for you.

How do you see the world of programming in 10 and 50 years and will Ruby and Rails have place in it?

I have no idea, really. That’s hard question. I don’t know. I can't see the future. I think Ruby is doing well. I’m excited about alternative Ruby implementations like Truffle Ruby, which is getting more and more attention. I’m also looking forward to Ruby 3. I think it’s gonna be easier to predict the future once Ruby 3 is realized. But I think that we have a strong community. Language is not everything, ecosystem built around language is also important. And I think we have very strong community which is evolving very fast these days. We see more and more new projects. It’s doing well. There are other languages, such as Elixir, which is getting a lot of attention these days. But it’s a young language with very young ecosystem so it’s gonna take a while for younger languages to get where we are already in terms of our experience and our knowledge and how we work together. I think Ruby is doing fine and it’s gonna be quite good for next few years.

In your opinion, what is the hypest technology in programming these days?

I don’t know. To be honest, I’m not really following hype. It’s to distracting. I would like to check out everything. But I think Elixir is a big hype. In a good way.

What advice can you give to “average programmer” to stand out the crowd?

Write and read a lot of code. That’s my advice for many years. I think people spend too much time discussing code and reading books instead of sitting together and coding. You can learn a lot from just this and discussing it afterwards. The more write and read - the better you become. For me, the fact that i’ve started contributing to open source helped me to learn so much. I’m sure that I’ve spend 10 times more if I was just relying on my job. So, contributing to open source is also a great way to learn not just how to write code, but also - how to work with people. You learn how to communicate, you meet a lot of different people, you work how to work in team, it helps you a lot. These two things are very important.

What makes you excited about your daily work?

I really enjoy using things that I’ve written. It’s because it motivates me to continue working on them and improving them and it’s such a joy for me to build them and use in a project as a tool. I also really like just working with people. I hate to be lone wolf, just writing stuff that nobody will see. Writing stuff that other people can use gives me a lot of joy and fun.

Do you have any plans to write a book?

I have a plan to write a book about my project - rom rb. This will be not too detailed book. It will explain rom rb in very basic way. Short introduction without going too much in the details because it’s big project. I don’t have time to write a big book and I want people to be able to quickly learn the basics and understand how it works. The cool part is it is possible to understand how rom works. It’s good to understand how tools that you use works.

Do you have nightmares related to your job?

I don’t remember any nightmares related to my work. I’m a happy man!
