Can anyone suggest me an open source data warehouse for Data Engineering Tasks where i can store data through ETL ingestion and train the model and save results.
you might want to check out caosdb (caosdb.org). it's a tool kit to put different data sources together and the ETL part should be covered well. the part regarding training the model, you might have to integrate another open source software into the tool.

Is sourceforge really the only host to let me see the countries from which my code is being downloaded and the OS they are using?
Is there a way on github, or other open-source hosts, to do the same?
I don't think so, considering the kind of data GitHub offered to be analyzed with Google BigQuery (and its GitHub Data Challenge)
You can see here an example of the kind of visualization you can produce from those data (no data bout countries in there):
GitHub data analysis
For instance:
The analysis of creation of new repository shows, that the pattern of busy or calm hours remains over the years.
For all those who are looking for Google Analytics for Github statistics maybe GA-Beacon could be a solution.

I am looking for a software to analyze survey data online.
My input should be SPSS file or anything similar (I don't mind writing a small tool to format the input, we enter the data using a proprietary software).
The idea is that the administrator should be able to upload the survey data to the website, and the users should be able to do simple analysis/data extraction.
The analysis should mostly be creating targets and generating cross tab reports.
I prefer open source software so I can write customized reports within the software.
It turns out there is a wikipedia article that answers my question:

I am looking for a tool, service, or framework that would allow us to expose our database to management. I have looked, although briefly, at JasperSoft and Crystal Reports. They looked "OK".
We are not afraid of writing our own queries so long as we can save them somewhere for later use by the business crowd. Ideally, the interface would be web based and reports could be emailed in a professional format.
I've never tried it but I read great things about Pentaho. Take a look at it.

Our project is based on J2EE and we would like to know if there is a open source maven-plugin which either integrates with cloc (Refer How can I measure source code statistics?) or other tools?
Use Sonar for that!
As you can see in the demo site, when this tool analyses your project, it provides a lot of statistics (using their internal tool, Sonar Squid which is a replacement of the old JavaNCSS) :
