Are there any good resources to get started with Scala web development? Any good tutorials, blogs or books?
I have checked https://www.scala-lang.org/ and it is a not good starting point for scala web development.
When it comes to backend, you could start from learning some frameworks like play or akka on which play is actually based(there are plenty of books about them), but if you mean frontend by "web development", there is also scala.js, but I would not recommend it to you since it has rather poor community and there is no many people that actually use it. If you are interested in some database connection then I recommend reading smth about slick.

I'm writing a uber-like mobile app for an academic project. This app is only a front-end for a system running on a server. This system, the backend is responsible for the user database, a search engine, messaging system and a location service (tracking system as in uber). I'm totally new to server development. My problems are:
How scala can be used to implement a backend?
How to handle concurrency, user authorizations, messaging and GPS data?
Additionally, In what cases should I use Kafka and Spark?
I would suggest you to go with play-framework. It has some learning curve, but once you start learning it seems quite interesting and is quite powerful too.
You must be familiar with scala, concurrency terms like future, actor and some database knowledge would be enough to start.
You can start by doing the examples provided in the documentation.

All the best with your learning:)

I am reading Programming in Scala 2nd edition which is based on Scala 2.8
I have read on Scala release notes that many concepts like Actors that are explained in the above book have been phased out.
Can you suggest which chapters I can skip from that book and read from other sources?
Edit 1: I have checked the change log which gave me good idea of new features which have been added.
Any good resources for learning
Akka Actors
Parrallel collections
Macros

I need to build a very scalable REST web service that will be consumed both by mobile apps, clients surfing the web, servers, etc...
Now as you can imagine this is a rather large task and I have no idea where to start, so I wonder if there are any good tutorials or books to help me on my way?
Thanks in advance!
A good starting point would be reading the "REST API - Design Rulebook" by "Mark Masse" published by O'Reilly Media, Inc.

I have been trying to follow mgwt and gwt-phonegap through code.google.com. It feels like a pain for me, because I can't find something properly described there for a beginner to follow.
Can any one plz suggest me a good tutorial site or examples for mgwt/gwtphonegap?
if you have questions on how to get started the mgwt user group ( https://groups.google.com/forum/?fromgroups#!forum/mgwt ) is a very good place to ask questions and there have been already a tremendous amount of questions about it on the group.
We are very friendly (especially to inexperienced users)
Check out the wiki:

http://code.google.com/p/mgwt/wiki/SetupProject
Check out the blog:

Also there are a couple of videos out there:

We did not document the basics of GWT MVP. This is done very nicely in the GWT docs.
