Without knowing the platform I can't give a direct answer. However, since you don't care about abandoned carts, then I would differ from my colleagues here and suggest storing it on the client. Why store it in the database if you don't care if it's abandoned? <br/>

Internationalised labels in Facelets |
|internationalization|facelets|java| |
Does [Facelets][1] have any features for neater or more readable internationalised user interface text labels that what you can otherwise do using JSF?
For example, with plain JSF, using h:outputFormat is a very verbose way to interpolate variables in messages.

You can use the provided system views to do this:
eg
select * from INFORMATION_SCHEMA.COLUMNS
where table_name = '[table name]'
alternatively, you can use the system proc **sp_help**
eg
sp_help '[table name]'

You can use the Any< T>(T=>bool) operator instead of SingleOrDefault< T>(T => bool). And it should probably be Expression< Func< bool>>. You can also make it an extension method on the DataContext.
if (!table.Any(where))
{ db.InsertOnSubmit(record);
db.SubmitChanges();
}

The list that Dori posted is pretty comprehensive, and I don't think that its possible to list all the libraries out there since there might be one being written even as I type (it seems to be a passion for some people).

On top of the fact that the member function can modify global data, it is possible for the member function to modify explicitly declared mutable members of the object in question. |
I think you're very right on both bullet points. If they're storing the passwords hashed, as they should, then password length doesn't affect their DB schema whatsoever. Having an open-ended password length throws in one more variable that a brute-force attacker has to account for.

Should I inject things into my entities? |

When using an IoC container, is it considered good design to inject other classes into them? i.e. a persistence class |
First, do not assume that banks have good IT security professionals working for them. [Plenty don't][1].
That said, maximum password length is worthless. It often requires users to create a new password (arguments about the value of using different passwords on every site aside for the moment), which increases the... |
The keyword [mutable][1] on member variables allows for const functions to alter the state of the object at hand.
And no, it doesn't cache data (at least not all calls) since the following code is a valid const function that changes over time:

Corey is correct, but bear in mind that any member variables that are marked as **mutable** *can* be modified in const member functions.
It also means that these functions can be called from other const functions, or via other const references.

Different situations require different approaches. Personally I perfer refactoring to a better design whenever possible. Refactoring leads to less bugs than a rewrite.

WCF is the best choice. It supports a number of different communication mechanisms (including Named Pipes) and can be completely configuration driven. I would highly recommend that you take a look at WCF.

One way to handle this might be to extend the XmlHTTPRequest object with an explicit timeout method, then use that to determine if you're working in offline mode (that is, for browsers that don't support navigator.onLine).

There are two varients of UNION. 'UNION' and 'UNION ALL'

At the basis there is no guarantee that such a thing will ever work perfectly. As long as the browser developers find ways to do their own thing rather than the 'standard' way of doing things, you will have differences.

You can run the web server on any port. 80 is just convention as are 8080 (web server on unprivileged port) and 443 (web server + ssl). However if you're looking to see some web site by pointing your browser to a different port you're probably out of luck. Unless the web server is being run on that port explicitly yo... |
Perhaps this is obvious, but FWIW this will only work if the web server is serving requests for that website on the alternate port. It's not at all uncommon for a webserver to only serve a site on port 80. |
You can only access a website throught the port that is bind with the http server.
Example: i hava a web server and it is listening for connections on port 123, the you only can get my pages connecting to my 123 port. |

You might want to give this a go:
