  • Allan Kelly: Introducing the Agile Basics video series
    Doubts because so much of what I do is interactive, exercises, following questions and I don’t know how to translate that into pre-recorded videos or other online material. If my courses were just me talking to the audience then maybe, but thats not what I do in my Agile training courses. don’t know how to approach videos, how much work is required? How much editing? So I decided the best thing to do was to experiment. To find out for myself. ve even heard stories that some people can make good money doing this.

  • EF 6.x Code-First and Model-First with Trackable Entities 2.1
    'Until now Trackable Entities has required the Entity Framework Power Tools to reverse engineer Code-First model classes from an existing database. Tools for Visual Studio 2012 and 2013 , so that you can use the same Entity Data Model wizard to generate context and entity classes using either the Code First or Model first approaches. When the tools were first released, the ability to customize the T4 templates used for generating Code First classes was undocumented. From there you can select which database objects to include. Trackable Entities v2.1 DataMember].

  • Converting the RavenDB Northwind database to a more denormalized form
    'In a previous blog post I demonstrated how to denormalize the RavenDB sample database and use the DenormalizedReference and INamedDocument types from the RavenDB documentation to make life really sweet. Updating the database on the server Instead of downloading each document, updating the structure and saving it back to the server it is much better to do these sort of actions on the server itself. Fortunately RavenDB has the capability to execute database commands on the server. So lets look at a better solution fixing the database. Why JavaScript?

  • Denormalizing data in RavenDB
    'One of the things with RavenDB, or NoSQL document databases in general, is that you don’t do joins to combine data. Normally you try to model the documents you store in such a way that the data you need for most common actions is stored in the document itself. When you first get started with document databases that feels strange, after all with relational databases we are taught to normalize data as much as possible and not repeat the same values. The result is that for most operations a single IDocumentSession.Load() is enough to work with a document. 13: }. 16: {.

  • Do you know the way to Falmouth? (Agile on the Beach)
    Which means, in the days and weeks before the conference I’m going to have several people asking me for my advice on how to get to Falmouth. So here is some advice on getting to Falmouth and the conference, not everything you could know, but the main points I tell people when they ask. If you want a quick summary skip to the end.) Firstly even some English people are stumped when they stop and consider how to get to Falmouth. And if you are coming from outside the UK its even more likely that you need to stop and think.

  • Duplication and Cohesion
    There is a hidden, often forgotten, label that belongs on this scale: Cohesion The rule you want to follow is this: Choose the lowest duplication for the natural cohesion Examples of low cohesion My last name is ''Falco''. Examples of high cohesion An advantage of working in many PHP systems is that no matter what I do to a page the worst I can do is mess up that single page. PHP systems tend to have high duplication. The down side of this is when something changes, for example: how sales tax is calculated on a page. Unfortunately, this is only half the story.

  • Real-World MVVM with Entity Framework and ASP.NET Web API
    'I just completed a sample application using Simple MVVM Toolkit together with Trackable Entities to build a real-world N-Tier solution with a WPF client and portable POCO entities that are automatically change-tracked and sent to an ASP.NET Web API service that uses Entity Framework to perform asynchronous CRUD operations (Create, Retrieve, Update, Delete). The nice thing about this sample is that it demonstrates how to build a complete end-to-end solution. CancelEdit simply points Model to the original and discards the edited version. Enjoy!

  • False Projects
    For example: There is no end date to the work, it goes on and on, rightly or wrongly. Some might think I’m playing word games here but I think its important, I think we need to be clear about our terms. If the this is a new idea to you see my Why Projects Don’t Make Sense post.) PRINCE 2 (the UK project management standard) offers the following definition of “a project” “A temporary organization that is needed to produce a unique and predefined outcome or result at a pre-specified time using predetermined resources.” Please, hear me out. We create confusion.
