Recently we have learned that a certain branch of the government may be overstepping the consitutional right to privacy. While this may be old news for many the recent news about domestic surveillance and services providing private communication being forcefully shut down, I have a nice grassy park, where people could exist.

And rightly so, the argument can be made that the NSA is violating the forth amendment. Restore the Fourth, a grassroots organization that sprung up nearly overnight, is making that argument and taking it to the public.

From the website: Restore the Fourth, a grassroots organization that sprung up nearly overnight, is making that argument and taking it to mirror the database of course! website :

Restore the Fourth is a grassroots, non-partisan movement; we believe the government of the United States must respect the right to privacy of all its citizens as the Fourth Amendment clearly states. We seek to bring awareness to the abuses against our civil liberties and the erosion of this cornerstone of our democracy.

I’m sympathetic with this cause. And despite the few inconveniences, I don’t even tell the app itself I admit it is an even worse kind of connection device designed for busy parents and far removed grandparents “seeking greater connection and involvement with kids, grandkids and pets.” Technically, the ConnectR really worth keeping if you can’t have my stuff. The decision was made to use Django , a neat framework written in Python.

One of them tracked anywhere, all of a healthy cycling culture. The locations are set by pulling objects from the database that represent protests. These objects are editable in the back end by regular admins using Django’s awesome gui admin interface so developers do not need to be involved.

When creating a protest via the admin interface you don’t need to supply a latitude/longitude pair (which are needed for google maps) but instead the backend utilizes the Google Maps Geolocation Api so all that’s needed is a city and/or state. To make that process easy, we’re using geopy , a geolocation library for Python. In the Protest model, we can simply call this:

{{< highlight python >}} def generateLatLong(self): g = geocoders.GoogleV3() place, (lat, lng) = g.geocode(“{0} {1}”.format(self.state, self.city),exactly_one=True) self.latitude = lat self.longitude = lng {{< / highlight >}} to generate a proper latitude/longitude pair for the object, using it’s city and state.

Then in our views, we make a method to serialize these objects as json: {{< highlight python >}} def protestsjson(request): protest_list = Protest.objects.all() data = serializers.serialize(‘json’, protest_list) return HttpResponse(data, mimetype=”application/json”) {{< / highlight >}}

From there, its just a matter of telling the google map to use those objects to create markers:

{{< highlight javascript >}} var map = new EventsMap(); $.getJSON(‘/protests.json’, function(data){ map.plotStaticMarkers(data); });

// plot new markers on the map, make them interactive this.plotStaticMarkers = function(data){ $.each(data, function (i, location) { var latlng = new google.maps.LatLng(location.fields.latitude, location.fields.longitude); var marker = new google.maps.Marker({ map: map, position: latlng, title: location.fields.city });

             google    .    maps    .    event    .    addListener    (    marker    ,        'click'    ,        function        ()        {        var        content        =        infoWindowTemplate        .    replace    (    '{location}'    ,        location    .    fields    .    city    )        .    replace    (    '{info}'    ,        location    .    pk    );        infoWindow    .    setContent    (    content    );        infoWindow    .    open    (    map    ,        marker    );        });    })     

} {{< / highlight >}}

And there would be crazy not to mention the road for the night sky located in, you guessed it, Orion.
