• High speed Internet access has changed the world immeasurably. A dazzling array of divides have been bridged – from educational and political to cultural and linguistic. Some gaps have not been narrowed, however, and some have been widened. This is particularly true for rural communities in developing countries, where building Internet infrastructures is not economically attractive due to the high cost of reaching users with low purchasing power.

    AirJaldi is a social enterprise established in Dharamsala, India with aim of narrowing these gaps. Early in 2005, following the deregulation for outdoor use of WiFi in India , we began our work by helping to create the Dharamsala Community Wireless-Mesh Network in cooperation with the Tibetan Technology Center.

  • Over the last few years we witnessed a change in the development world. Not only did products become more social in themselves, but the whole process of development became much more transparent. Companies offer open source versions of their products and give access to their data via Application Programming Interfaces or short APIs. Software is being hosted on repositories with social aspects, training material is spread across the social web, people leverage existing social graphs and build products live in the cloud.

  • GeoWebCache is a Java web application used to cache map tiles coming from a variety of sources such as OGC Web Map Service (WMS). It implements various service interfaces (such as WMS-C, WMTS, TMS, Google Maps KML, Virtual Earth) in order to accelerate and optimize map image delivery. It can also recombine tiles to work with regular WMS clients.

  • rackview is a tool for visualizing the layout of rack-mounted equipment. It can load data either from database tables or from a flatfile
  • mplementing a MapType to act as a base map type can be a time-consuming and laborious task. The API provides a special class that implements the MapType interface for the most common map types: map types that consist of tiles made up of single image files.
    This class, the ImageMapType class, is constructed using an ImageMapTypeOptions object specification defining the following required properties:
    tileSize (required) specifies the size of the tile (of type google.maps.Size). Sizes must be rectangular though they need not be square.
    getTileUrl (required) specifies the function, usually provided as an inline function literal, to handle selection of the proper image tile based on supplied world coordinates and zoom level.
    The following code implements a basic ImageMapType using Google's traffic tiles. Note that the map type is inserted into the map's overlayMapTypes array:
  • Sensorly gives you free access to 100% community-powered hyper-local coverage maps. Our crowd of mappers is collecting data around the clock using regular phones and producing a true picture of carriers' current coverage.

  • openBmap is a free and open map of wireless communicating objects (e.g. cellular antenna, Wi-Fi, Bluetooth). It provides tools to mutualize data, create and access this map.

    Help us build a free database ! Open source logging applications are available for Android2 phones, WindowsPhone6 and the openmoko freerunner freesmartphone.org phones.

  • Coverage Mapper is a crowd sourced cellular coverage mapper. The Coverage Mapper application runs on your mobile device (currently only available for Android), collects signal strength data, tied to your location, and submits it to our server. With the data from many people, accurate coverage maps are generated, to give you a better idea of the coverage in areas you care about.
  • But what is a CellID?: a CellID is the unique number of a GSM cell for a given operator. Your phone is always connected to a Cell, and by nowing this number, you know the Cell, and by knowing the position of the cell, you know where you are. There is some accuracy issue, as the cell can cover from several hundreds of meters to several kilometers, but this could be a very good starting point to locate yourself.
