Sabbatical Week

Filed under: Uncategorized — ajlopez @ 3:21 pm

Yesterday, Friday September 14th, I started my second sabbatical week of the year. During this “long” week (it ended at Monday September 24th), I’ll be dedicated to study, investigate, read, write, think, organize and create. I’m interested in work on some points:

– Add functionality to my project AjGenesis (code generation), write more examples, and post about its features

– Study about frameworks and technologies, from Java, .NET to Smalltalk, from EJB 3x to Windows Presentation Foundation, from Enterprise Service Bus to Architecture and Patterns

– Write posts about my progress (if it doesn’t written, it doesn’t exist… 😉

– Review other open source projects that I have started

– Read a pile of books about software development, business of software, and technology.

This is an ambitious plan, but I hope it will be interesing and full of fun.

You can see my other activities for this week (not related with software development) in my personal blog (Spanish).

LINQ in Orcas Beta 1

Filed under: Uncategorized — ajlopez @ 5:51 pm

I’m using a virtual machine with Orcas installed Beta 1, the version to come of Visual Studio 9. In another one “post” I’ll enumerate the main new features, but now, I want to concentrate in showing a small great step to me, that brings built-in code generation for LINQ. (code of this example in Dbml1.zip)

Those that saw LINQ, the Microsoft technology, in some way, an object relational mapping, remembered that there was a command line tool named SQLMetal, that generated code to make that mapping. Now, the SQLMetal is still alive, but, following with the idea of to do everything from the Visual Studio, the Orcas version provides a new type with item: Linq to SQL.

In the example, I dragged tables from a connection of data SQL Server, and soon they appeared in the new designer (in this case, using a datasbase from a Hands On Lab Orcas Beta 1, on a database similar to the one of DinnerNow, with restaurants, menus, and items of menus):

In a file of code produced automatically by “designer” (Redmond boys saw the light, the generation of code… for years that people have been adding more code generation utilities in Visual Studio versions, e.g., software factories… ), in this example, a DinnerNowDataContext:

public partial class DinnerNowDataContext : global::System.Data.Linq.DataContext { [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] public DinnerNowDataContext(string connection) : base(connection) { } [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] public DinnerNowDataContext(global::System.Data.IDbConnection connection) : base(connection) { } [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] public DinnerNowDataContext() : base(global::DbmlLibrary1.Properties.Settings.Default.DinnerNowOrcasLabsConnectionString) { } public global::System.Data.Linq.Table<Menu> Menus { get { return this.GetTable<Menu>(); } }

in a similar way as the code generated by SQLMetal tool. As before, it defines “business entities” that are the classes that correspond to the database tables:

[global::System.Data.Linq.Table(Name="dbo.Menu")] public partial class Menu : global::System.Data.Linq.INotifyPropertyChanging, global::System.ComponentModel.INotifyPropertyChanged { private global::System.Guid _MenuId; private global::System.Nullable<global::System.Guid> _MenuTypeId; private global::System.Guid _RestaurantId; private global::System.DateTime _StartDate; private global::System.DateTime _EndDate; private global::System.Data.Linq.EntitySet<MenuItem> _MenuItems; private global::System.Data.Linq.EntityRef<MenuType> _MenuType; private global::System.Data.Linq.EntityRef<Restaurant> _Restaurant; [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] public Menu() { this._MenuItems = new global::System.Data.Linq.EntitySet<MenuItem>(new global::System.Action<MenuItem>(this.Attach_MenuItems), new global::System.Action<MenuItem>(this.Detach_MenuItems)); this._MenuType = default(global::System.Data.Linq.EntityRef<MenuType>); this._Restaurant = default(global::System.Data.Linq.EntityRef<Restaurant>); } [global::System.Data.Linq.Column(Storage="_MenuId", Name="MenuId", DBType="UniqueIdentifier NOT NULL", IsPrimaryKey=true, CanBeNull=false)] public global::System.Guid MenuId { get { return this._MenuId; } set { if ((this._MenuId != value)) { this.OnPropertyChanging("MenuId"); this._MenuId = value; this.OnPropertyChanged("MenuId"); } } }

Thanks to the people of Southworks by the virtual machine with Orcas Beta 1.

Security, SOA, WCF and SaaS: all in one

Filed under: Uncategorized — ajlopez @ 3:16 pm

Matias Woloski has posted an article about the security implementation on a Software as a Service .NET demo application LitwareHR. It’s very interesting to see in action the declarative capabilities of Windows Communication Foundation, the use of Federated security, SAML tokens, and authorization policies. The post is here:

Enjoy and learn!

CoRank opening

Filed under: Uncategorized — ajlopez @ 9:03 am

There is a new site, from Rogelio Bernal Andreo, founder of www.egrupos.com , www.elistas.com and www.zoomblog.com

It’s www.corank.com, with a Spanish version http://es.corank.com/

According with its home page:

coRank is a site where you can share whatever you find interesting on the web with people who value your opinion, and where you can also find what’s interesting for people whose opinion are important to you – your sources – whether they know who you are or not.

In coRank, your Front Page is yours only, and likely different than any other, as it is based on how the-people-you-select react to upcoming stories and submitted websites.

You can read about its features at Take a tour

Great job, Rogelio!

Sabbatical Week

Filed under: Uncategorized — ajlopez @ 9:38 am

Today is the first day of my sabbatical week, a week dedicated to think, read, write, create and put order in my life. In my opinion, a “free” week is a must, twice a year: you can put all effort in one subject or you can explore new possibilities, without links to daily activities.

This time, during these days I’ll write down some ideas. I want to write some code that is in my mind, and rearrange some open source projects. I hope to publish any advance, here, my technical English blog, and at:

http://www.msmvps.com/lopez (technical Spanish blog)
http://ajlopez.zoomblog.com (personal Spanish blog)

The last month was very exciting for me, full of ideas and challenges, and now, it’s time to put order on all that stuff.

A software architect

Filed under: Uncategorized — ajlopez @ 11:39 pm

 The architect concerns himself with the depth and not the surface, with the fruit and not the flower.
