The following test:

        // 20081211 this test fails on purpose, fix in model engine.
        [Test]
        [Category("Integration")]
        [Ignore("test crashes test server.")]
        public void ImportVanCouverNetworkAndRunCalcGridAtFixedInterval()
        {
            ImportVanCouverNetworkAndRun(true);
        }

must be written as

        [Test]
        [Category("Integration")]
        public void ImportVanCouverNetworkAndRunCalcGridAtFixedInterval()
        {
            Assert.Fail("test crashes test server, update model dll to a stable one and remove this line.");
            ImportVanCouverNetworkAndRun(true);
        }

Then test will always fail on the build server.

Quantum GIShas a decent properties dialog. It is possible to create a user defined coordinate system. (EPSG CRS style).

Adding symbology to layers.

The Attibute table has a nifty feature of querying the data.

Issues discussed:

• Focus on One Team-Member At a Time
• Pair Switching
• Who Should Drive
• Pair Mentor
• Pair Learner
• Uninterested & Distracted Pair
• Spellchecking Pair
• When Not to Pair
• Core Pairing Hours
• The Simplest Thing That Could Possibly Work
• Mandate Code Review

Interesting project, maybe we can switch to it from hbm.xml. The advantages are obvious:

• Easier refactoring
• Automapping
• Smaller

Traditional HBM XML mapping

<?xml version="1.0" encoding="utf-8" ?>  
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"  
  namespace="QuickStart" assembly="QuickStart">  
  
  <class name="Cat" table="Cat">  
    <id name="Id">  
      <generator class="identity" />  
    </id>  
  
    <property name="Name">  
      <column name="Name" length="16" not-null="true" />  
    </property>  
    <property name="Sex" />  
    <many-to-one name="Mate" />  
    <bag name="Kittens">  
      <key column="mother_id"/>  
        <one-to-many class="Cat"/>  
      </bag>  
  </class>  
</hibernate-mapping>  

Fluent NHibernate equivalent

public class CatMap : ClassMap<Cat>  
{  
  public CatMap()  
  {  
    Id(x => x.Id);  
    Map(x => x.Name)  
      .WithLengthOf(16)  
      .Not.Nullable();  
    Map(x => x.Sex);  
    References(x => x.Mate);  
    HasMany(x => x.Kittens);  
  }  
}
