naming

Why do some websites I see have a URL in the form a.b.example , and others are in the form of b.example/a ? For example, why is it gist.github.com instead of github.com/gist ? unor These are different components . See section 3 of the URI standard for a list of components and their definitions. https://gist.github.com/ The authority (or more specifically, the host ) is gist.github.com . The path is / . https://github.com/gist The authority (or more specifically, the host ) is github.com . The path is /gist . As https://gist.github.com/ would typically also have paths like the second URI (e.g.,

Of course I could name the objects in my list all manually like this: #create dfs df1<-data.frame(a=sample(1:50,10),b=sample(1:50,10),c=sample(1:50,10)) df2<-data.frame(a=sample(1:50,9),b=sample(1:50,9),c=sample(1:50,9)) df3<-data.frame(a=sample(1:50,8),b=sample(1:50,8),c=sample(1:50,8)) #make them a list list.1<-list(df1=df1,df2=df2,df3=df3) But it makes a lot of work if I have let's say 50 objects with long names. So is there any way to automate this and make the names inside the list the same as the outside objects? Find the names, then call mget . If there is a pattern to the names of each

I see many people talking about the term SUT, but do not understand why they use that term. SUT is what you want to test? Where does this term come from and what does it mean? For example in this test, what is my SUT? [TestMethod] public void UsersAction_should_return_IndexAction() { const long id = 1; UsersViewModel viewModel = new UsersViewModel() { SelectedUsers = new long[] { 1, 2, 3, 4 } }; ActionResult result = _controller.Users(id, viewModel); result.AssertActionRedirect().ToAction("Index"); } The System Under Test (SUT) from a Unit Testing perspective represents all of the actors (i.e

Which is your preference? Let's say we have a generic Product table that has an ID, a name, and a foreign key reference to a category. Would you prefer to name your table like: CREATE TABLE Products ( ProductID int NOT NULL IDENTITY(1,1) PRIMARY KEY, CategoryID int NOT NULL FOREIGN KEY REFERENCES Categories(CategoryID), ProductName varchar(200) NOT NULL ) using explicit naming for the columns (e.g. Product Name, Product ID), or something like: CREATE TABLE Products ( ID int NOT NULL IDENTITY(1,1) PRIMARY KEY, CategoryID int NOT NULL FOREIGN KEY REFERENCES Categories(ID), Name varchar(200) NOT

There's one thing I haven't found in rfc 2616 and that's a "canonical" name for a request/response pair. Is there such thing? 4.1 Message Types HTTP messages consist of requests from client to server and responses from server to client. HTTP-message = Request | Response ; HTTP/1.1 messages Taking this as a template, which word would you put in the following sentence? A single complete HTTP ... consists of one HTTP Request and one HTTP Response HTTP-... = Request Response roundtrip? cycle? The spec calls them "exchanges" (or "request/response exchanges"), In HTTP/1.0, most implementations used

I have component which needs to update the database for the customer and customer address (via JDBC). Is it appropriate to call the CustomerAddressDAO from the CustomerDAO? Or create a separate "CustomerDataManager" component which calls them separately? You can do it, but that doesn't mean you should. In these cases, I like to use a Service ( CustomerService in this case) that has a method call that uses both DAOs. You can define the transaction around the service method, so if one call fails, they both roll back. The problem with DAOs that call other DAOs is you will quite quickly end up
