questions about leaky-abstraction

Fluent interfaces and leaky abstractions

What is a fluent interface? I can't find a good definition of this, but all I get are long code examples in a language I am not very familiar with (e.g. C++). Also, what is a leaky abstraction? Thanks ...

leaky-abstraction

Python: an iteration over a non-empty list with no if-clause comes up empty. Why?

How can an iterator over a non-empty sequence, with no filtering and no aggregation (sum(), etc.), yield nothing? Consider a simple example: sequence = ['a', 'b', 'c'] list((el, ord(el)) for el in sequence) This yields [('a', 97), ('b', 98), ('c', 99)] as expected. Now, just swap the ord(el) out for an expression that takes the firs...

jQuery subtleties

Community wiki. At least I think it's worthy of that. I've always been interested in some of the inner workings of jQuery, and a great question prompted this. I'm not talking about cool stuff you can do with jQuery but more subtleties of how it works. Maybe links to helpful posts could come in here. One example is that $() is interc...

Does MVC Contrib fulfill its promise of increasing productivity in ASP.NET MVC

I am knee deep in starting a new ASP.NET MVC project. Several tutorials have recommended the use of MVC Contrib. I wanted to get the opinion of the Stack Overflow community if it fulfilled its promise of increasing productivity with ASP.NET MVC. Basically are the benefits of MVC Contrib worth adding another leaky abstraction to my applic...

N-layered database application without using an ORM, how does the UI specify what it needs of data to display?

I'm looking for pointers and information here, I'll make this CW since I suspect it has no single one correct answer. This is for C#, hence I'll make some references to Linq below. I also apologize for the long post. Let me summarize the question here, and then the full question follows. Summary: In a UI/BLL/DAL/DB 4-layered application...

Design issue: RMI needs explicit exporting of objects

I have two applications communicating via RMI, a slave server (of which there will be multiple) and a master server. Following good abstract design, I'd like to implement the slave in a way that it doesn't know that when talking to the master, it's using RMI (so that the two apps can also be run inside the same JVM, for instance): publ...
