It comes with a built-in benchmarking script. Please try running ... |
I have the following solution structure. This is a business domain (for an amount transfer operation in bank account) which will be called by a WCF service. Is the solution structuring correct?
Data Acess Layer does not create domain objects. It just pass database record wrapped in another simple object (DataEntities... |
This is the first piece of code I wrote on my own. I tried to use everything I know, like functions, loops and variables. Is it good or could it be simpler?
Please be hard as you can be with me because I feel my programming knowledge is quite poor and I end up using Google for solving my problems.

I'm working on some code that deals with mangled C++ function names. I'm displaying these to the user, so to help with readability of some of the really long C++ template class/function names, I'm removing some of the template arguments based on how deeply nested the template argument is.
The code below works fine, but... |
I have two more methods the same as this except that they query a different table. Is there another way to know if the result of the query is null? The hasher.CompareStringToHash() method is not allowed to have a null value.
If it's not null, it proceeds to an else condition, and inside that it checks if the encrypted ... |
I'd like to get input on a F# actor that coordinates receives around a blocking message buffer. The actor is a piece of code that continuously tries to fetch messages from Azure Service Bus.

As I thought about this question on SO, I realized that I wanted to implement either a string trimmer or a trimmed string inputter.
This is what I came up with, but I have a nagging feeling I could have done better.
Would you critique this, please?

I'm building a GWT application for GAE, using JDO for Datastore access. I use and Entity class for data mapping, so it contains lots of Persistence annotations:

My goal in the method is to write a simple clustering program that determines if a clustering document is valid based on these rules:
All clusterings start with < and end with >.
Every start clustering <something> must be followed (eventually) by an end clustering </something>.
Clusterings must be properly nested as f... |
