Probably the most painful thing for software developers is to be restricted in technology choice which they want to use in a development. You pay for a conference ticket, listen about new cool frameworks, development approaches or tools... Then you return to office with huge enthusiasm and desire to try at least something on real project. Unfortunately such initiative very frequently meets resistance from different sides: team members don't want to learn something new, a manager thinks it is risky, a product owner hurries with a next release, etc.

How often do you need to write or read files? This is pretty common task in any more or less not trivial project. Image upload process, CSV or XML parsing, XLS report generation etc. All these operations imply input or output processing. So I'm going to make an overview of the most powerful library for work with files in Scala.

JVM is too small for two leaders. That’s how I want to start a post about Java vs Scala. By the way, I had used Java for a long time, but then switched to Scala and wasn’t happy with that decision. Luckily I have understood how to use its features in order to be more productive developer. Make yourself comfortable, it's going to be a very interesting conversation about marketing in a programming languages world. Yes-yes, exactly conversation, because I encourage my readers to write comments with their thoughts about the topic.

Hello, dear Reader! I apologize for a such loud title of the article, but you should know how it's important for me to engage the readers to discussion. Not so long time ago, I decided to systemize my knowledge of object oriented programming in Scala. That was awesome idea! And now I want to share with you all mini-topics which I underlined as important, but many developers forget about them.

Today I want to write about a dream of every Java developer - pattern matching. While a switch statement works only with limited number of types, including primitive values, strings and enums, the pattern matching feels confident with almost any argument type. I'm going to demonstrate a batch of examples where pattern matching is useful.

I enrolled to Functional Programming in Scala specialization on Coursera. It consists of 5 courses which will take around 180 days. First course in the specialization is Functional Programming Principles in Scala. I already completed the first week and learned some stuff about recursive functions. So It's time to share some knowledge.

That's not a secret that Scala is very popular programming language in BigData industry. And you may heard before that Scala is a data-centric programming language. This means not more, that with its help you can work with a data more easier comparing with other languages. Important roles in this play two Scala features: case classes and case objects.
