F# - Fluent NHibernate RTM

Well, I finally got the courage to download the RTM version of Fluent NHibernate. I wrote about using Fluent NHibernate in an earlier post (June 28, 2009), so a lot of this is repetitive and some is new. I have highlighted in yellow the important stuff. First, I create a simple class ------------------------------------------------------------------ using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace StockPrices {     public class COMPANY {         public virtual int Id { get; set; }         public virtual string COMPANY_NAME { get; set; }         public virtual string COMPANY_TICKER { get; set; }         public virtual int ASSET_TYPE_ID { get; set; }         public virtual int IS_ACTIVE { get; set; }     } } ------------------------------------------------------------------ The COMPANY class has...

Excuse Me?

Well, now I have definite evidence that there is no intelligent life on earth. Last week an appeals court  threw out Lucent's $358 million award against Microsoft for infringing on a patent allowing MS Outlook users to enter a date by clicking on a calendar.  Go here Does anyone else think this is galactically stupid? I have have just three questions. (1)  What idiots on a jury think clicking on a calendar is worth $358 Million? (2)  Does Lucent think that because they're such a failure they have to resort to frivolous lawsuits to make money? (3)  What on earth is the patent office thinking...

F# - Classes (In progress)

So, today I decided I would try to figure out how classes work in F#. I have decided to make a Bank object.  The first thing I tried is this: #light type Bank() = class     nCustomers : int     nEmployees : int end This does not work!  I get the error: Program.fs(6,5): error FS0010: Unexpected identifier in member definition. Who knows what that means. So, I start poking around and find that I need to use the 'val' key word to create a public property.  So the next thing I tried is this: type Bank() = class     val nCustomers : int     val nEmployees : int end This also does not work!  I...

Railroad Traffic Data - WE 8/29/2009

Well, I just got a look at the rail traffic data for the week ending 8/29/2009. We actually see a fairly sizable increase -- all non-intermodal traffic increased by 2.1% over the previous week: Two percent may not sound like a lot, but in the world of railroads it is a fairly big deal.  Total carloads are now 285,580, well off their low of around 250,000 just a few weeks ago. Let's look at coal: Coal loads were up just about the same 2.1 percent.  This stands to reason as coal makes up nearly half of all carloads. Chemicals also showed a fairly good sized...
