How easy is to switch from Rabbit to Kafka in existing solution, to replace one implementation (Rabbit) with other (Kafka)? We are about to use Rabbit in our implementation but we want to see if it is possible in the future to replace it with Kafka.

It is possible, and I've seen people do it - but it is a big project.
Not only the APIs are different, but the semantics are different. So you need to rethink your data model, scaling model, error handling, etc. And then there's testing.
If you don't have tons of code to update, and the code is localized and you have both RabbitMQ and Kafka experts on the team you may be able to get it done in a month or two.

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 fairly new to golang, and trying to identify the best tools for the job. Currently I am evaluating the following packages:
https://github.com/mattes/migrate
https://github.com/DavidHuie/gomigrate
https://bitbucket.org/liamstask/goose/
I was wondering if anyone had any experience with these (or other packages) and could provide some comments.
We use mattes/migrate at work and are very happy with it. It works with plain SQL files, handles file naming by itself and can easily be automated via CLI. It doesn't do anything Go specific.
With gomigrate you need to create the files yourself and write code for executing the migrations.
Take a look at https://github.com/pressly/goose, a maintained fork of https://bitbucket.org/liamstask/goose/.

Anything similar to MySQL Proxy for PostgreSQL? [closed]

I am looking for something similar to MySQL Proxy. The purpose is to modify incoming queries on the server. I am not looking for alternative ways to achieve the same. My best guess at the moment is to modify GridSQL, but this adds complexity and it takes time. I have asked this question before in a vastly different way and got no relevant results, so I deleted that question and added this one.
Edit: It is important that the client can continue to utilize the PostgreSQL protocol, so the package I am looking for needs to communicate using it.
You might take a look at sqlrelay which has the ability to route and filter queries.
http://sqlrelay.sourceforge.net/sqlrelay/router.html
If you want to rewrite the queries I think sqlrelay falls short.
You might otherwise look into PostgreSQL's rules, which can be used to substitute or rewrite queries:
http://www.postgresql.org/docs/8.4/interactive/rules.html
You can refer to the following postgresql-aync driver project.
