Setting up Geowave and integrating it with GeoServer for the development environment

by viggy — Categories: FSMK, project, Uncategorized — Tags: , , , , , , , — Leave a comment

Geowave is a library used to store, index and analyze geospatial data on top of Accumulo which is a free software implementation of Google’s Big Table. Accumulo in turn makes use of Zookeeper to handle distributed synchronization and uses Hadoop FileSystem for distributed and scalable storage of the data. Geowave decomposes multi-dimensional data to single dimensional data using a transformation called as Space Filling Curves. GeoServer is a java based server which provides a platform to view and edit geospatial data. Hence at an abstract level, we can summarize that the data which is transformed by goewave and stored(ingested) in Accumulo can be extracted and viewed from geoserver.
Following article will explain how we can setup the system to have Geowave and Geoserver working with Accumulo for a development environment.

Project Idea: harddisk search engine

by viggy — Categories: FSMK, project — Tags: , , , , , — 2 Comments

I do have loads of media files in my two external harddisks, one of 3TB and another of 1TB. And overtime the data is all over the place, in some cases, there are duplicates also and there is currently no way, I can easily remember if I have a particular data or not. Over all its a mess. Hence I need a good way to arrange all of this data and have a cache of its metadata in my laptop, so that it becomes very easy for me to search whether I have a particular media file available with me or not. Media can be anything from movies, documentaries, songs, iso images, series, etc.

So this are the requirements of such a software:

  •  Do full scan of HDD connected and collect all data available in it.
    • User should be able to give a minimum/maximum size of interest(files less than say 1MB may not be of importance)
    • User should be able to give formats of interest(User may just want video files to be listed/searched)
  • Should be able to update an existing scan so that only new files are added to it again
  • Using the collected data, user should be able to search a particular file based on filename/filetype/size etc

Project Idea: Hacker of the week through github and gitorious performance

by viggy — Categories: FSMK, linux, project, tech — Tags: , , , , — Leave a comment

Technology Required: Php/Python web frameworks like Django/RoR, Git, Mysql/MongoDB/Any other database.
FSMK has many students who have started using github and gitorious and keep working on their own projects or contribute to any existing free and open source projects hosted there. The idea is to have a web portal which keeps tracking the contribution/activity of various FSMK students on gitorious and github and rank them based on various factors. Ultimately, every week, Hacker of the week will automatically be announced. The project is to have a web portal to do this automatically every week without needing any manual intervention. There should be one way for students to register to this portal along with their github/gitorious id and the admin of the portal will approve the student’s registration. Similarly College of the week can be announced. The portal should also maintain a record of all the previous week results.

In Version 2, When a new user is registering, certain criteria needs to be met like number of active days on github/gitorious, number of times contributed to projects, minimum score based on various other criteria. Also whenever the coder of the week is announced, it needs to send email to fsmk-discuss mailing list and also update in FSMK Facebook group.
