Hello Scott,

I am using terraform already and keep state in terraform cloud. I've heard that there are also another options i.e. keeping state in azure blob. Does your book covers that stuff too?

Thanks,
Krystian

Hello and welcome to the ranch.
I have a question - I read java 8, and some of scala from "for the Impatient" series, can i expect that it will be the same style? I liked that
Hello and welcome to the ranch!

Does this book covers a lot of same things in the same way compared to previos edition?
Second question, do you think that other jvm language have a chance to gain more popularity than java in the feature?

John, welcome to the ranch!

I Have a question. What do you think about feature of spring and lagom? Spring is really popular for microservices. There arÄ™ other frameworks that are non blocking and reactive but spring 5 also gonna provide writing in such a manner. But there are also other important aspects that spring has support and easier to achieve. I've got a feeling that it is more mature.

A lot of java developers don't want to learn scala, because they find that syntax is weird and too hard to understand. I have found out that it happens to people that are developing in Java for many many years. Do you have any idea why is that?

Hello and welcome to the ranch!

I would like to ask you few questions. What's your experience of using akka with java, because i saw one chapter in the book about it? I've heard, that it's way easier and nicer with scala, because of the syntax and akka api that can provide?

What do you think about future of java? Do you think that it's possible someday to see pattern matching, case classes(I think they will come in java 9, heard somewhere about it), implicits objects and others?
Now we have only Optional, we don' t have a Some, None, Nothing and I think even, if we would have we have so many code already written in old style and using null to represent no value is normal for most projects and libs.
I know Javas Lang provide some features but it's not "it".
Hello and welcome to the ranch!

I have some questions
1. Are there some solid and lots of advices how to really apply FRP to legacy, about some traps etc? Back-end and front-end.
2. Is FRP explained really well, on examples and how it really differs from 'traditional' synchronous model? From the back-end size - when it really does matter on performance and can serve more (thread pools)?
3. Is it building an app for a whole book or it's more like short examples exactly to the point?
4. tips for debugging

Thanks!

Thanks for your answer !

I will begin with Java Performance and then look on The Java Performance Companion I am Java developer but got some Scala developer friends who are also interested in this topic That's why I've asked. Both are JVM languages so that knowledge looks really useful

Hello and welcome to the ranch!

I was thinking about reading a book "Java Performance" and i have a question to you Charlie How does this new book differs from "Jave performance"? I know, that new book includes jdk 1.8. Which one would you advise to read first?
And one more question to all:
All of the advices that you provide in this book is mostly about JVM so it's also gonna be useful for scala developer, am i right ?

I don't have any experience with docker, mesos etc. Is this book a good place to start?

Hello and welcome to the ranch!

Will software engineer(backend) will find something usefull in this book? Let's say, he is cooperating with UX people but he is not making UX decisions.

Hello and welcome to the ranch!

Have you worked a lot with legacy systems ?
Thanks for your answer
I got your point, those tests are much more readable, easier to maintain and parameterized tests... it looks really good. Maybe example with data creation in Java is too exaggerated to show how java can be verbose, because you can use static factory methods or builder.
Anyway, i will give it a try for sure!

One more question: what about mocks in spock? Are they all "Nice"?
