A brief overview of C++ Type conversion and RTTI

There have always been confusion around C++ explicit type casting, particularly when dealing with polymorphic pointers and references. In this post I am trying to explain uses of C++ specific type conversion functions when dealing with user defined classes.

Using Xcode to develop on your remote Linux systems

 November 03, 2013

Developing code on remote Linux systems slows down development process therefore using a local IDE such as Xcode on mac and mounting the file system locally make significant difference in file editing and developing. Besides once could compile and test code simultaneously on two systems.

SSH config - permission denial while accessing remote system

 January 05, 2013

Nowadays most developers work remotely or somehow connect remotely by running remote connections. These connection are mostly linked to remote compute clusters, remote desktops and remote servers also including cloud computing servers such as Amazon EC2. Accordingly its equally difficult to remember intricate IP addresses also it becomes worse when you list of different computers to connect. In this post I will try to explain and guide you through the process of making password less ssh connections.
