Hey! Looks like you are familiar with Scala. And I believe you even develop some apps locally using it. A main mission of the code is to help people to solve their problems. But how your apps can do this, if they are running locally on the laptop? In this post I want to show the easiest way to deploy a Scala application.
Have you ever heard about a median? I'm talking about that thing from mathematician statistics, which represents a "middle" value of a data set. If you are reading this, I bet you hear about it. Moreover you want to know how to implement a median function in Scala. So I'll show you how it can be done.
So as you already know, I've enrolled to Functional Programming in Scala Specialization on Coursera. Currently I'm passing through the 4th course of the series "Big Data Analysis with Scala and Spark". If to be more precise, two days ago I completed an assignment for weeks #2 and #3. As usually I'm going to share my experience.
So this week is an official start of 4th course from Scala Specialization on Coursera. I mean Spark course. This is an outstanding event, because so many students have been waited for this almost 1 year :) What does it mean for me? Firstly I need to keep focused on video lectures and assignments. Secondly, I decided to share my impressions about the course here.
In this article I want to show a real difference between curried functions and partially applied functions in Scala. This question is pretty common for those developers who started learning Scala without previous experience in functional programming. Moreover, this blog post may be useful, even for experienced Scala developers, because based on my experience I have had incorrect understanding of the difference between the curried functions and partially applied functions.
When I work with Scala collections, I always keep in mind that there are two types of operations which I can perform: transformation operations and actions or like someone call it aggregation operations. The first type transforms a collection into some another collection. The second one type returns some value.
I want to share with you a small piece of my project. It's about Scala programming language. If to be more precise it's about the most simple way of Scala studying. Why I said the most simple? Well, because I have a solid knowledge of mainstream problems which occur during Scala studying. So I invite you to discuss my job.
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.
