Below is a whole bunch of information to help you prepare mashups!
# [Hosted Developer Tools](#hosted-developer-tools)
### Sourceforge
Subversion, Git, Mercurial, Bazaar, CVS, issue tracker, wiki, release file downloads. Unlimited free use for open source projects.
You can create your own Sourceforge project at [http://sourceforge.net/](http://sourceforge.net/)
### Google Code Project Hosting
Git, Mercurial, and Subversion code. Issue tracker, wiki, release file downloads. Unlimited free use for open source projects.
You can host your Google Code project and get access to developer tools, APIs and documentation at [http://code.google.com/](http://code.google.com/)
# The basics of being a data scientist
* Find the people and tools you need to prove/show/find. This rest of this page will help with the latter.
Please note, there are a combination of Analysis and Visualisation tools in each of the major categories below.
# [API Development](#api-development)
So an API isn’t just an XML file 
A good web based data API:
* Is logically organised
* Can filter returned data
* Can return results in different open formats (CSV/JSON etc.)
* Is efficient and responsive by using caching and databases appropriately
* Handles errors gracefully
* Monitors and controls access (to show benefit realised of API and prevent abuse)
* Provides appropriate documentation with examples
Some people like sensis [http://](http://developers.sensis.com.au/)[developers.sensis.com.<wbr>au</wbr>](http://developers.sensis.com.au/)[/](http://developers.sensis.com.au/) use a provider like[http://](http://mashery.com/)[mashery.com](http://mashery.com/)[/](http://mashery.com/) or [https](https://apigee.com/)[://](https://apigee.com/)[apigee.com](https://apigee.com/) or [http://](http://apiaxle.com/)[apiaxle.com](http://apiaxle.com/)[/](http://apiaxle.com/) or [http://www.3scale.net/](http://www.3scale.net/) which handles making a good API for them.
Atlassian have a great page on what makes a good API [https](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[://](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[developer.atlassian.<wbr>com</wbr>](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[/display/REST/](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[Atlassian](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[+<wbr>REST+API+Design+Guidelines+<wbr>version+1</wbr></wbr>](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)
# [Data Visualisation](#data-visualisation)
Most of the categories to follow have visualisation tools specific to their purpose.
You can find some data visualisation “essential”\. tools below:
[http://www.visualisingdata.com/index.php/2011/07/part-6-the-essential-collection-of-visualisation-resources/](http://www.visualisingdata.com/index.php/2011/07/part-6-the-essential-collection-of-visualisation-resources/)
Also check out [http://thejit.org](http://thejit.org/) & [http://www.senchalabs.org/<wbr>philogl/</wbr>](http://www.senchalabs.org/philogl/) (contributed by Matt Adcock)
# [Augmented Reality Tools](#augmented-reality-tools)
### buildAR
buildAR was the world’s first AR Content Management System with the first early version launched back in 200\. as a bit of a test to see if people were interested in being able to create their own augmented experiences. MOB Labs officially launched the new improved buildAR at the Augmented Reality event in Silicon Valley in May 2011.
[http://buildAR.com](http://buildar.com/) (normally a 1\. day free trial but GovHack attendees on the day will get a fully activated account for a month. If you are a GovHack attendee want full access now to play, just sign up for a trial and then forward your GovHack Eventbrite registration email to govhack [at] buildar.com and they’ll set you up for the free month fully activated account within a couple of days.

## Analysis
### PostGIS
[](http://www.govhack.org/wp-content/uploads/postgisexample.jpg)PostGIS is an extension for the PostgreSQL database server that allows you to store and manipulate geospatial data on a large scale. For example finding which points are in an area or what points are closest . It is also very useful for storing geospatial data because it can convert between all major formats including ESRI Shape files and Google Earth/Maps KML.
### Quantum GIS
[](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_m50afbe88.jpg)QGIS is a graphical desktop application that allows viewing and editing of geospatial data. Some good base maps are available by adding the WMS layer/server [http://irs.gis-lab.info/](http://irs.gis-lab.info/)
## Visualisation
### Google Fusion Tables/ChartsBin/[OpenHeatMap](http://www.openheatmap.com/)
[](http://www.govhack.org/wp-content/uploads/fusiontablesscreenshot.jpg)Input a numerical values and areas to a spreadsheet and maps are produced
### [Cartographer.js](http://cartographer.visualmotive.com/)
[](http://www.govhack.org/wp-content/uploads/cartographerjs.png)Input data as JSON and maps are produced.
### OpenLayers/Google Maps/[Leaflet](http://leaflet.cloudmade.com/)
[](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_512fcbe1.jpg)Display points and different layers. Leaflet is the easiest to use if you just want to show points with popups when clicked on.
### NASA World Wind/Google Earth
[](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_4dda24a4.jpg)Google Earth provides 3\. viewing of KML/GML files which represent points and shapes, both through a desktop application and a web plugin. These can be extended with interactive features that allow you to view by timeline or have animated tours between different points. You can also develop and customise your own viewer with the open source [NASA World Wind toolkit.](http://goworldwind.org/demos/)
###
Tabular Data Tools](#tabular-data-tools)
## Analysis
### Excel / Calc
Great basic analysis and viewing. Older versions can be limited to 6500\. or so rows. Eg [http://www.tcij.org/training-material/car/data-mining/3474](http://www.tcij.org/training-material/car/data-mining/3474)
### [DataWrangler](http://vis.stanford.edu/wrangler/)/[Google Refine](http://code.google.com/p/google-refine/)

### PostgreSQL/MySQL
[](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_209ee972.jpg)Next step up, large datasets can be manipulated/extracted efficiently for example [http://www.postgresql.org/docs/8.4/static/tutorial-window.html](http://www.postgresql.org/docs/8.4/static/tutorial-window.html) , no built-in data visualisation though.
[Miso Dataset](http://misoproject.com/dataset/)
### R Statistical Language
[](http://www.govhack.org/wp-content/uploads/rstudio-windows.png)Advanced data analysis, can find and visualise trends in large datasets. Some reference resources to learn the language [http://cran.r-project.org/doc/manuals/R-intro.html ](http://cran.r-project.org/doc/manuals/R-intro.html)There are also some addons that provide graphical interfaces that make it easier to use such as Rattle [http://rattle.togaware.com/](http://rattle.togaware.com/) , RStudio [http://rstudio.org/](http://rstudio.org/) or Deducer [http://www.deducer.org/pmwiki/pmwiki.php?n=Main.DeducerManual](http://www.deducer.org/pmwiki/pmwiki.php?n=Main.DeducerManual)
## Visualisation
### [Tableau Desktop](http://www.tableausoftware.com/)

### D3.js (Data-Driven Documents)
[](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_m90d8020.jpg)Javascript visualisations that are more interactive or intricate than charts. Can be hard to learn but there are examples and easier to use premade visualisations such as [word clouds](http://www.jasondavies.com/wordcloud/), [realtime filtering of barcharts](http://square.github.com/crossfilter/), or [bubble trees for comparing amount sizes](https://github.com/okfn/bubbletree).
### Processing.js
Graph (relationships and networks) Data Tools](#graph-relationships-and-networks-data-tools)
## Analysis
### Neo4j
can be done using a preexisting tool like Gremlin or by writing a simple Java/Python/Ruby application. Queries can be tested in the built in data browser.
### [NetworkX](http://networkx.lanl.gov/index.html)
[](http://www.govhack.org/wp-content/uploads/chess_masters.png)
NetworkX is a social network analysis library for python. Many advanced analyses built in like finding communities within a graph. Also good for converting data into graphs.
### Palantir
