as the title suggests, I am trying to determine which language would better suit for the task at hand. I am probably going to include a GUI for the program. Am I okay to proceed with Java for this task or is another language recommended? Thanks

I can't speak on the pros or cons of writing such a program in C++. However, Java seems well suited to accomplish your task.

I understand that Chisel is a HDL/HCL language to overcome some of Verilog/SystemVerilog restrictions by using higher abstraction level.
And it is open source as well.
It might be a bit naive and presumptuous, but still I would like to ask.
My question is that why do so many similar efforts are working in parallel, e.g. Blusspec, spinalHDL, Pyha etc?
I mean, is there any reason why the development community may not choose one of these and concentrate efforts on stabilizing or enhancing one of these.
That's exactly what is happening now, it just takes a while to choose.
Although the past does not show that the best technology wins, let us hope it does this time.

I am currently working on a project where a Classical Music Generator is set to be built. A lecturer who is pretty much a expert in sound processing suggested that I could construct a Hidden Markov Model which will generate and return compositions.
There are already 80+ MIDI files from various renowned composers (Mozart, Bach, Beethoven...) in my computer ready for training. I just wonder will Pure Data be a suitable language for constructing HHM(s) which will finally return a generated music piece, from some MIDI inputs?
And if yes, any advice on how to utilise those MIDIs and put them into pieces for the HHM?
Thanks in advance.
Take a look at this library. It has HMM and a number of other machine learning algorithms that you could use.

You can also use HMM for signal related tasks. There is a paper here that you may find informative:

I need to parse html pages. As far as I know BeautifulSoap is most popular library for parsing html pages in Python. How about Haskell? I found a few of them such as tagsoup, http-conduit and xml-conduit, HXT
And I'm hesitating which one to choose. Your suggestions?
HXT is very complex platform and needed for specific tasks.
Very nice overview of HXT and its extension HandsomeSoup

I prefer html-conduit, described here https://www.fpcomplete.com/school/starting-with-haskell/libraries-and-frameworks/text-manipulation/tagsoup

I am developing web applications on asp.net with c#, is it good practice to keep comments on HTML(.aspx) pages?
Thank You in advance.
Yes, using comments always make good sense to a programmer.
Not only the developers, others who view the code can also understands the functionality of that particular function.
Adding comments is always like sharing your knowledge.
I think it's uselessness. You can insert comments text, autor, date etc. to MySQL and then print it by SELECT query

I want to create a new rails application and I'm not sure whether to use MySQL or Postgres. Which one is best and what is the difference between them?
UPDATE:
The project is a health-care project. It may contain more than 500 tables.
postgres is secure, fast, and full of features but comparatively tricky to use.
MySql has its own benefits along with large user community and vast materials. Immensely helpful if you ever get stuck.
But ultimately it all comes to your preference and framework (apart from rails if your app requires any) support.
