I would like to intercept, inspect, and rewrite every packet that goes in and out from the Internet to this subnetwork. The reason I need to do this is that I want to create a transparent (to both...
Hi, I'm developing a site in PHP which has some complex SQL queries and I would like to implement a caching feature to reduce the load on the database.

I'm am currently developing an ASP.NET intranet application. One of the features of this application allows users to search for items in order to manage them (edit, delete etc).

I ask because I have a situation where I am populating a generic List with multiple objects of the same custom type. The custom type is a POCO, there is nothing special about it. All of ...

I'm having a lot of elements which are generated and referenced (mouseover, clicks, position changes) a lot of times. I have the ID's of those elements at hand. Is it wise to store the document.getElementById(ID) calls in a variable, or is it faster/just as fast/slower to call document.getElementById() everytime? var app = []; var app....

For example, user has a node attached to his profile, menu item is "Create blabla" (link node/add/blabla) User doesn't have the node, menu item is "Create no...
I'm implementing object caching in a PHP application using APC. The issue is, that sometimes I will select something from the database based on different criteria. For instance, when a user logs into the web site, all I have is his username and password, so I'm going to select from the database based on the username. In other situatio...
