What are applications where search techniques or more specifically planning techniques are used? I am most interested in examples in use.
I know that A* is used for path planning in Robotics, that planning is used in logistics (details would be great) but what other usages are there?
For Search in general Google, etc come to mind with their inverted indices. Again, where else is it used?
For planning examples, including logistics challenges, take a look at this list. Each use case comes with multiple datasets and a problem definition.

Which one among the following NLP topics will be easier to work with?
Question answering
Paraphrase detection
Short text conversation
Author identification
The final one, Author identification. You don't need to have any understanding of the language you are dealing with, which the first three presuppose.
There is already a lot of literature on the topic; generally you identify features in texts, and map these onto a set of authors' known features. This can easily be done with cluster analysis or Machine Learning. So, it's not actually as NLP-heavy as the others.

I have a legacy Ruby on Rails API project, I notice that the project uses both active_model_serializer and Jbuilder. There are app/serializers diretory for active_model_serializer, and app/view/api/ for Jbuilder.
I'm new to Ruby on Rails API. From what I have read from the internet it seems active_model_serializer and Jbuilder are both used to deal with JSON data, there's even an article arguing which one is better.
I don't know which one is better, but is it a good practice to use both?
There's no problem in using both, but it's definitely not a good practice. It can be confusing for new people coming to the project. I'd say it's ok to use both if you transition from one to the other (most often from Jbuilder to AMS), but it's good to eventually stick with one of them.

Is there any list/source/dictionary with examples of a good class names somewhere over the Internet? I'm not looking for naming conventions, but rather for some resource with names and explanations when is proper to use them. I'm finding it somewhat difficult to came up with good names when I'm naming my classes so something like this will be helpfull:
SomethingBuilder - use in such cases...
SomethingRequest - use in such cases...
I suggest to look for repositories of frameworks or projects. They have plenty of classes with some really good names. Examples are symfony, kohana, cakephp, codeigniter, drupal etc... You can search for them on github to reach their repositories.
I know it is not a straight answer to your question but it still may be of help.

I am wondering how you would code an image vectorization program, al la vectormagic.com? Where would you even begin and would it be possible to create in any web based programming languages?
Behind vectorization programs are complex algorithms (for basic outline look on quite nice paper depixelizing pixel art by guys at Microsoft).
Anyway, it's possible to write almost in any language, that can process images, but those complex algorithms are pretty system resources expensive. So web based languages are quite inappropriate for that type of task.

What are the effects of multiplication of two different sound? An neither of them are constant, like two different songs, or one track of instrumental and one of vocals.
A simple Google search came up with this:
http://crca.ucsd.edu/~msp/techniques/v0.11/book-html/node77.html
Did you search for it at all?
But basically what happens is you end up creating an envelope where the second acts as a "coefficient" of sorts.
You also end up with a reduction of sound levels (since a decimal times a decimal is less both of them), so you'll need to amplify the signal a bit to retain volume.
The page I linked gives a lot more explanation and has a lot of the algebra needed to write up a code to implement it. Look there if you have any more questions.
