Bruce bought two pieces of DataTraveler USB 3.0 128GB (DT101G3) yesterday and found out that it is actually a USB 2.0 equivalent product in terms of data transfer rate (but it is equipped with a USB 3.0 interface indeed).
Kingston lures consumers with the USB 3.0 interface but sidesteps the issue of poor data transfer rate. In terms of this, DataTraveler USB 3.0 (DT101G3) is a fake USB 3.0.
Don’t buy it. I was really disappointed with these sneaky marketing tricks from Kinston.
I started a new custom domain service from wordpress.com and screwed up nlabs.wentzwu.com with the wrong domain, wentzwu.com.
I called for the online support tonight and received immediate and effective support.
Teams from wordpress.com did a good job, thanks!
I evaluated some tools, say PHP tools for Visual Studio, Ghost Doc and .NET obfuscators, on my box with Visual Studio 2012 update 3 and it caused the Visual Studio debugger to stop functioning just with any breakpoint set in the source. It takes me a whole day to fix it.
I don’t know why this works but it just works. Just have the IntelliTrace to collect both events and call information as the following picture shows:
After installing MySQL Connector/NET 6.7.4 today, my web app failed to start. It is because some MySQL membership providers were added to C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.config and the MySql.Web.dll assembly (MySql.Web, Version=220.127.116.11, Culture=neutral, PublicKeyToken=c5687fc88969c44d) could not be loaded.
Uninstalling the Connector/NET 6.7.4 makes my web app work normally again. Refer to http://bugs.mysql.com/bug.php?id=69808 for details.
As a .NET programmer, how do you define the following terms?
- Problem Domain and Domain Model
- Class and Object
- Object and Entity
- Business Object and POCO (Plain Old CLR Object)
- POCO and DTO (Data Transfer Object)
- Anemic Domain Model
- A domain model defines the scope of the problem domain, helps to the understanding of the problem domain among various stakeholders and facilitates communications between the technical and business teams through a shared vocabulary.
- A class is a structure of data and its manipulation logics or codes.
- An object is created on the basis of a class. A collection of objects contains one or more object instances.
- An entity is an object that has its own identity to distinguish one object from another.
- A business object, also known as domain object, is a regular object modeled after the real-world things. A business object separates domain model from implementation details.
- A POCO, also known as persistence-ignorant objects, is a business object without persistence methods. A POCO may implement properties (or data members), validation rules and/or any other business logics but methods related to persistence.
- A DTO is an object designed to move data between layers or tiers. In terms of the costly process to move data across boundaries, a DTO usually implements properties or data members only.
- Anemic domain model is the use of a software domain model where the domain objects contain little or no business logic (validations, calculations, business rules etc).
