CryptHook is a modular implementation for securing existing applications with symmetrical block cipher encryption. It works by hooking the base system calls for network communication send/sendto and recv/recvfrom. CryptHook will work with existing applications that rely on these system calls.

In this tutorial we are going to see how to use Sockets in Android Applications. In Android, sockets work exactly as they do in Java SE. In this example we are going to see how to run an Server and a Client android Application in two different emulators. This requires some special configuration regarding port forwarding, but we are going to discuss this later on.

This article focuses on network issues and techniques for making fast-action video games playable via modem on the Internet. Although there are some definite benefits to working with a specialized online game service (particularly in the administrative areas of player rendezvous, billing, tournament organizing, ranking, distribution, and maintenance, and in the technical areas of richer APIs and better network performance), the discussion here will apply to designing games for the Internet in general.

With the surge in popularity of multiplayer games such as Halo, Worlds of Warcraft, and Counter-Strike, it is becoming increasingly important for game developers to support multiple players. Unfortunately information on how to write multiplayer on-line games is lacking -- you can find the occasional article that discusses one aspect, but no single resource exists that touches on all the relevant areas and how they relate to each other.

This is a investigation of a pattern for event-driven applications. The REACTOR pattern decouples different responsibilities and allows applications to demultiplex and dispatch events from potentially many clients.

The Reactor design pattern handles service requests that are delivered concurrently to an application by one or more clients. Each service in an application may consist of serveral methods and is represented by a separate event handler that is responsible for dispatching service-specific requests. Dispatching of event handlers is performed by an initiation dispatcher, which manages the registered event handlers. Demultiplexing of service requests is performed by asynchronous event demultiplexer

Here are a few notes on how to configure operating systems and write code to support thousands of clients. The discussion centers around Unix-like operating systems, as that's my personal area of interest, but Windows is also covered a bit.

A simple IRC-powered botnet, allows you to control an arbitrary number of machines via simple IRC commands. The remote-workers communicate with and report back to the control program via an IRC backchannel, while the operator of the Botnet issues commands directly to the control program.

What bottlenecks are there and how do you avoid them?

This FAQ answers the most commonly-asked questions about Winsock. The bulk of it was written back when mailing lists and news groups were the best ways to find people who knew Winsock deeply, and so drew heavily from those resources.
