Scala doesn’t offer many DB access libraries. Slick and Anorm seem to be the most popular – both being available in the Play framework. Despite both serving the same purpose, they present completely different approaches. In this post I’d like to present some arguments that might help when choosing between these two.
Few weeks ago when I was working on my pet project, I wanted to make it an SBT plugin. Since I had to spend some time studying SBT docs, I decided to write a short tutorial explaining how to write and deploy a SBT plugin.
Building servers with non-blocking IO has been quite popular these days. Tests have shown that it does actually improve scalability of web applications. However, my experience show that it comes at a cost. In this post I am going to discuss some negative aspects of writing asynchronous code based on Scala’s Futures.
Scalatra is an awesome, lightweight web framework for Scala. It’s perfect for building REST APIs. One of its less known features is support for asynchronous programming using Scala’s Futures.
I’m back from a rather lenghty break and would like to continue the Scala for C# developers series. So far I have covered the syntax, the basics of OO in Scala and functions. In this post I will look at the
Option type and pattern matching.
This is the second post in the series. Click here to see the previous part.
Recently, after three years of focusing mainly on the .NET platform, I’ve changed jobs. My current company uses Scala for server-side programming in their projects. I was very happy for this transition. Both Scala and C# can be considered hybrid functional and object-oriented programming languages. However, Scala seemed to feel more functional than C# – more built-in functional constructs, tighter syntax, default immutability, etc. While this is true, I was surprised how many similarities these languages. I concluded that as long as you have already seen the more functional side of C#, it is really easy to transition to Scala. This post series will discuss some of the similarities and differences between Scala and C#.
This post is a continuation of Is array of Dogs an array of Animals? Covariance, contravariance and invariance explained – part 1.
Welcome to the first post on my blog. I would like to dedicate it to a topic that sounds quite intimidating but is in fact quite simple to understand. There are already good explanations of type variance to be found on other blogs or Stack Overflow but I would like to take a broader approach and look at how different programming languages deal with it.
