    I've been using git-svn for OpenLayers development for some time now. Although git-svn isn't so easy to work with, I'm quite happy with it for OpenLayers.

    So I have a git-svn clone of http://svn.openlayers.org/trunk/openlayers on my development machine. I use this git repository for "trunk …

  2. Server-side OpenLayers

    I've been interested in server-side JavaScript lately. As a proof of feasibility (to myself) I've put together a node.js-based web service that gets geographic objects from PostGIS and provides a GeoJSON representation of these objects.

    For this I've used node.js, postgres-js and OpenLayers.

    node.js is a lib …

  3. Y Combinator

    I've been reading "The Little Schemer" from Daniel P. Friedman and Matthias Felleisen. Very interesting reading.

    The nineth chapter introduces the Y Combinator function, a pretty interesting beast! Quoting Crockford: "one of the most strange and wonderful artifacts of Computer Science". As a primer, here's how the Y Combinator looks …

    From my reading and understanding there are three types of tests:

    • Unit tests: a unit test tests a single function (e.g. an object method). A unit test must take care of isolating the tested …

  5. MapFish and GeoExt

    Matt Priour recently asked about the future of the client part of MapFish, and more specifically whether it will be replaced by GeoExt. This is actually a question that every MapFish user should be asking :-). Anyway I thought an answer to that question could make a post on my blog …

  6. Additions to the MapFish Protocol

    We recently added new stuff to the MapFish Protocol.

    As a refresher, let's first take a look at what the MapFish Protocol had before the new additions.

    (Note that you'd need the JSONovich FireFox extension to see the output of the examples given below in your web browser.)

    This post shows how one can secure TileCache with Pylons and Repoze.

    In a Pylons application one can run a WSGI application from within a controller action. Here is a simple example:

    class MainController(BaseController)
    
        def action(self, environ, start_response):
            return wsgiApp(environ, start_response)
    

    TileCache is commonly run from within …

  8. FeatureServer Versus MapFish Server

    In Misc.

    I thought I could say a few words on the differences between FeatureServer and MapFish Server.

    First, FeatureServer and MapFish Server have similarities. They share a similar, REST-based protocol, for creating, reading, updating and deleting features.

    The main difference between the two: FeatureServer is a standalone application, MapFish Server is …

    The things I really like in MapFish 1.0:

    • The PDF Printing Library. Everyone wants to print maps, Patrick has turned everyone's dream into reality. The PDF Printing Library is great, it supports fancy stuff like vector rendering, map rotation, legend, etc. See this page …
