I have two small structs (might change to classes later) that get loaded into Generic lists. The loading of the lists is what I'm asking about. Can it be done better or more object-oriented?
You'll notice I'm using MS Enterprise library for data access to a SqlCe database.
I'm just looking for some opinions on this cod... |
In his KnockoutJs 1.3 beta post, Steve Sanderson has an example of using Binding providers ("5. Binding providers (and hence external bindings)") where he makes a comment in the JSFiddle JavaScript tab that says "// This syntax would be way more succinct with CoffeeScript".
How would this actually be accomplished?

I have been tasked with implementing a secure account login system for a website's content management system. I have built a solution around an access masterpage that handles all account access functions. Here is the Page_Load

I just made this sort method. It runs fine and the code looks okay in my eyes.
Is is possible to optimize it so it runs faster? If it's \$O(n^3)\$ now, it would be interesting changing it to \$O(n^2)\$ or something like that.
Side question: This is \$O(n^3)\$, right (I only like \$O(n^2)\$ and below)?

I would like some advice to shorten down this snippet, give it more efficient flow and look. Review should focus on keeping it as a compact single method (except the two public props). The DataType and MeasureStatus is an enum. Readability is of course more important than compactness.

As part of our sprints, we do peer review each others code.
Here is the code that I am reviewing.

string emailAddress = string.Empty;

I'm currently looking at this Boost::CRC example code which I have also inserted below.
I always try to look for suggestions for improving my own coding style when I encounter well-written and well-formatted code.
This code definitely looks like good code, but two things puzzle me about this:
is it good practice to co... |
Here it is the best I can do (I am a noob using Haskell):
map (\(y, z) -> y + z) (zip x (tail x))
I'm looking for a point-free solution.

After checking some incoming coding competitions, I feel I may want to develop a little bit more on my coding skills and style using some basic algorithms/data structures.
The following two pieces of Java code are about some LinkedList operation. Can you take a quick look and give me some feedback about the accuracy, e... |
I'm trying to convert from random bytes to integers within a range. Basically converting as such:
byte[] GetRandomBytes(int count) -> int NextInteger(int min, int max)
Another way to think about it would be: I have a RNGCryptoServiceProvider but would rather have the interface to Random.
My current algorithm works out... |
