Dare Obasanjo aka Carnage4Life - ASP.NET Caching vs. memcached: Seeking Efficient Data Partitioning, Lookup, and Retrieval
by brianwaustin (via)I recently discovered memcached which is a distributed, object caching system originally developed by Brad Fitzpatrick of LiveJournal fame. You can think of memcached as a giant hash table that can run on multiple servers which automatically handles maintaining the balance of objects hashed to each server and transparently fetches/removes objects from over the network if they aren't on the same machine that is accessing an object in the hash table. Although this sounds fairly simple, there is a lot of grunt work in building a distributed object cache which handles data partitioning across multiple servers and hides the distributed nature of the application from the developer. memcached is a well integrated into the typical LAMP stack and is used by a surprising number of high traffic websites including Slashdot, Facebook, Digg, Flickr and Wikipedia. Below is what C# code that utilizes memcached would look like sans exception handling code

Instrumentation: Powerful Instrumentation Options in .NET Let You Build Manageable Apps with Confidence
by brianwaustin (via)Instrumentation allows you to determine the running state of a system once it has been deployed. This is crucially important today since the people supporting systems are unlikely to be the same people who developed them. Like good error handling, instrumentation is best done at development time. A sound instrumentation policy must be established at the beginning of the development process to determine what should be instrumented, why, where, and how.

Overview to the Windows Server 2003 Security Guide
by brianwaustin (via)The Windows Server 2003 Security Guide provides specific recommendations about how to harden computers that run Microsoft® Windows Server™ 2003 with Service Pack 1 (SP1) in three distinct enterprise environments—one in which older operating systems such as Windows NT® 4.0 and Windows® 98 must be supported, one in which Windows 2000 is the earliest version of the Windows operating system in use, and one in which concern about security is so great that significant loss of client functionality and manageability is considered an acceptable tradeoff to achieve maximum security. These three environments are respectively referred to as the Legacy Client (LC), Enterprise Client (EC), and Specialized Security – Limited Functionality (SSLF) environments throughout this guide.
