• Firefox and Chrome slow on localhost; known fix doesn't work on Windows 7

  - by Herb Caudill

  Firefox and Chrome are known to be slow on localhost when IP6 is enabled. In previous versions of Windows, the simplest fix is to comment out this line from the hosts file, as explained in the answer to this question. ::1 localhost However, as noted in this question, in Windows 7 this line is already commented out: # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost Is there an alternative way to disable the ::1 localhost reference in Windows 7?

• Implementing prototypes OR instantiating class objects

  - by intuited

  I'm wondering how to implement prototypal inheritance in Python. It seems like the way to do this would be to either use a metaclass to cause instantiations to actually be classes, rather than objects, or use some magical powers to transform an existing object into a class. The second method would seem to be more flexible, in that it could be applied to existing objects of varied types, while the first would likely be more convenient for typical use cases. Insights on the practicality of these two approaches, as well as alternative suggestions, are hereby requested.

• Is there a preferred approach for Roles aware links in MVC 2

  - by Ralph Shillington

  If an action has been decorated with [Authorize(Roles="Administrators")] is there a way to not display the link for the currently logged in user who is not in the declared role? It seems to me that baking a lot of if statements into the view to give this kind of "selective disclosure" is contrary to the MVC way, but I'm not sure what the alternative is?

• Is prefixing Windows Forms control names with their type OK?

  - by name

  I have seen many responses that say that prefixing variables with their type is bad, since C# is statically typed and we have Intellisense, but I find that prefixing the names of the controls is useful because I don't need to remember the name of the controls or switch to the designer frequently. For example: btnLoad // Button tbFilePath // TextBox tvFileSystem // TreeView Is this considered bad? If it is, what's the alternative?

• Centralizing / Abstracting MSSQL Data from Multiple Tables / Databases

  - by davemackey

  If one has a number of databases (due to separate application front-ends) that provide a complete picture - for example a CRM, accounting, and product database - what methods are available to centralize/abstract this data for easy reporting? Essentially, I'm wondering if there is a way to automatically pull data from multiple databases into a central repository that is continuously updated from the three databases and which can be used for reporting? I'm also open to alternative best practice suggestions?
