Have you ever gotten this error with Visual Studio 2008?  This is a very frustrating error because it will not allow you to build your project unless you shut down studio and restart it, but this should not be so.  I have tried lots of things to make this go away but to no avail.  If anybody has a solution to make this go away for good I am all ears because from my understanding, this problem has been around for quite some time with Visual Studio.

Database Replication vs. Message-Based system

January 9th, 2012 by admin No comments »

Replication is a topic I have been keenly interested in the past month or so.  I have been studying various NoSQL database engines including RavenDB, MongoDB, CouchDB to name them in particular.  Each one of the technologies have their strengths and weaknesses but when it comes to replication in particular, CouchDB seems to be way ahead of the game with their implementation of selective, or filtered replication.  I wonder what are the benefits of using a message-based system to get your json documents to your database vs just letting the database handle them via replication.  Any thoughts or comments are welcome.

Example of CouchDB Replication Document

January 7th, 2012 by admin No comments »

Welcome to my blog about my various adventures in software development. I like many others figured that if you are doing this stuff as a career you might as well write about it every once in a while. In the coming weeks I plan on writing about my discoveries in the CouchDB world as I am investigating its use in an upcoming project at my current job. To begin I have just placed an example of a JSON document to perform replication in your couchdb instance. I will clean this up in the coming weeks.

{
          "_id":"by_clientId",
          "source": "http://localhost:5984/test_couch",
          "target": "http://localhost:5984/test_couch2",
          "continuous": true,
          "create_target": true,
          "filter": "replicateFilter/clientFilter",
          "query_params": {
              "clientId": 1
      }
 }
