Hello Marcello,

Do you cover in your book big data search optimization techniques?

Hello Dean,

In your opinion, with deprecation of implicit conversions in Scala 3, do you think it better for newcomers to learn 'extension methods and givens' or one should still start with learning implicit conversions in order to work with Spark (I don't think Spark will migrate to Scala 3 quickly enough) and later move to Scala 3?
Do you compare the two (implicit conversion and givens) in your book?

Hi Dean,
thank you for answering my previous question. Here is another one.
While '_' symbol in Scala was certainly overloaded (imports and placeholders), in Scala 3 to be replaced with *.

What is the main reason for the replacement of '_' with '*'?

To me - this makes Scala more Java-like

Hello Dean.

Do you think positional formatting is going to be widely adopted with version 3 of Scala?
Is this an attempt to lure Python programmers into the world of Scala?

Thank you for answering my previous question.
I have another one:

If pandas library is single threaded, working partitioned data would not bring any benefits; the data would still be accessed sequentially and not in parallel manner, right?

Basically I am trying to find a good use case to use pandas vs Spark.

Hello Ana,
I am very new to pandas library, but not new to Spark. Here is my question:
Since Spark is written (mostly) in Scala, does an application performance written in Python suffer from having to convert Scala datatypes to Python and back?

Hello Paul,

I have been always wondering if to be truly successful in programming one needs to have a CS (Computer Science) degree.
What is your opinion regarding this?

Hello Yehonathan,
Could you provide a good example where Data-Oriented programming would NOT be a good choice for a coding style?

Hello Samer,
Could you describe a use case where GraphQL API would NOT be a good choice?

Hello Amy and Mark,
I looked in the TOC of the book. Does the 'platform' you are using in the book (Spark and Neo4j) require a certain version of Spark (let's ay >2.0) or any (1.6, for example) could be used? Do you have a 'platform' - a VM stored somewhere or a Docker we can download?

Alex
Hello Ben,

What (text) editor would you recommend to use while crafting and testing regular expressions?
Currently I am using Notepad++ - it has pretty good support for RegEx although somewhat limited.

Thank you,

Hello Daniela,

I have another question.
How does your book compare to Scala for the Impatient by Cay Horstmann (of course if you are familiar with that book)?

Hello Daniela,

I have another question.
Do you cover Promises and Futures composition? (mainly: for-comprehensions)
