#23are there any other big company relying on scala for their core infra ?
Twitter, Etsy rely on Scala as their main tech stack.
You can probably list a large chunk of the big banks. I know quite of few of City of London's big investment banks all continually look for scala developers. In the same breath I would probably list the gambling companies which seems to be on scala bandwagon as well...
In the UK the public sector (GDS) are investing in scala based projects. E.g The HMRC have about 200 scala developers (me included).

http://www.squants.com/ seems like a great library for studying, since it's inherently intuitive, self contained, well documented, and exposes a terrific api.

#25Learning Scala is such a pain. Either you follow a large book completely and master it across several months/years or go through overly complicated online guides and get discouraged. I understand it's a large, advanced language, but the community has to seriously work on making things a bit easier for beginners like me. Just look at how easy it is to learn Go or Rust, their official tutorials are amazing and free on…
This might be true, but I don't think it is hard as the general opinion is. I think it's mostly about the technique and patience. You can't expect miracles at once or a wow factor. I generally started using it for smaller projects or parts where I could experiment a bit, and started using it as a better Java. I also played CodinGame with Scala. As things caught pace I started evolving it a bit and looking into refactoring and so on. Too be honest, I'm not too advanced, but I kinda like the pace. Word of warning: Java is still my main language at work, but the language choice is not my decision. However, whatever happens with Scala or me in the future, one thing stays, I became a better Java developer because of Scala. Also, the colleagues got interested after looking into some Akka Streaming apps :D .

#27Earlier quoted context omitted.
I agree about painful learning curve for Scala. Problem I think in very divergent community and in different approaches for a every single problem (unlike for example Python or Go): OOP vs FP, Typesafe vs Typelevel, scalaz vs cats, Cake Pattern vs sanity. There's a also a problem that most powerful Scala techniques are there "by accident" [1] and unlikely will (or should) appear in official guides. Also I disagree th…
I'm aware it's probably not intentional, but you describe Scala as being eclectic, and then immediately criticize Scala For The Impatient for presenting it as eclectic! However, I do feel like you're right. For instance, the section on XML literals probably should have been avoided, since that feature doesn't fit nicely with the rest of the language and most of the time isn't necessary to know.
I think that's totally consistent. It's bad that Scala is so eclectic. It's also bad that introductory books present Scala as eclectic instead of selecting the "best" subset of Scala to teach.

The real question: is it worth it? Up to now I could successfully avoid learning Scala. My problem with it is the complexity that the language by itself introduces and the readability of code that comes out at the end. Maybe I am just valuing simplicity too much when it comes to programming languages. Anyways thanks for the impatient guide!
Tons of companies make big bucks out of making stuff more complex then selling training and consultancy services. Lightbend is one of them.

twitter/util is very well written, and useful.
After that you could look into the spray.io source: it is quite complex, but the API it exposes and how extensible it is is amazing... They also coined the _magnet pattern_ which is pretty cool, and probably less abused than the cake pattern.

Impressive list.
Most of those companies use a bunch of technologies, Scala being only a small part of their stack. Only a few of those companies use Scala as their main language.
