Financial Risk Management Mind Maps

An asset class (finance) agnostic mind map of risk mgmt pathways taken by Sell side firms.. Recently drew on paper.. Every single node in this tree deserves a sepaarte detailed explanation or another mindmap, I'd keep extending in future. Following is just a starting point..

C++11 std::thread Construction and Assignment Tricks

C++11 arrived with std::thread and related classes built within the standard. With the move semantics in place, the construction and assignment practices of 'std threads' deserve a small write up. Let's define a 'Runnable' first: class Runnable { public: virtual void operator ()() = 0; virtual ~Runnable(){} }; class Task : Runnable { public: void operator ()() { //do sth here.. } }; //later.. #include <thread> Task runnable; std::thread t1; //not attached to any thread std::thread t2 ( runnable ); //attached and running Copy Construction of std::thread is not allowed std::thread t3 ( t2 ); // compilation error std::thread t4 = t2; // compilation error error : use of deleted function std::thread (const std::th

C++ logging using Apache Log4cxx on Linux

I'd demonstrate the set up of Apache log4cxx on Ubuntu 12.x in following steps: 1. Download all required packages 2. Build Log4cxx via Apache Maven 3. Use the libraries in a NetBeans C++ project on Ubuntu Linux. Reference URL: http://www.yolinux.com/TUTORIALS/Log4cxx.html This URL is quite detailed and explains things for other *nix operating systems as well. I wanted to start with minimum steps required, hence this post. I have a Windows 7 desktop and have Ubuntu 12.x 64-bit running on it via Oracle Virtualbox. So Ubuntu is running as a guest on my Windows 7 host. [The reference URL mentions different versions of 'libaprXX' libs but we have to use 'libapr1-dev' and 'libaprutil-dev', will see that later.] Prerequisites (install all of the following one by one) autoconf and automake --> sudo apt-get install autoconf automake libxml2 and libxml2-devel ( http://xmlsoft.org/ ) --> sudo apt-get install libxml2 libxml2-dev gmp (

..Where Apache Camel meets Spring JMS

This post is relevant for developers who are aware of Apache Camel and use its JMS component to consume from a JMS broker. We are only discussing the message consumption part here. I'm assuming you are conversant with Camel's terminology of routes, endpoints, processors and EIPs. If not, following is a good place to start: Link ---> Apache Camel Home Ever wondered what happens underneath when a Camel consumer route is defined to take messages from a JMS endpoint ? This post is an attempt to explain how Camel integrates with JMS via Spring APIs and how the business logic defined in a Camel route is invoked ? Following is a simplified sequence diagram showing the set-up process which will eventually lead to message consumption from JMS broker. . Creation of JMS endpoints in a camel context is initiated by definition (via Java/XML DSL). A JMS endpoint takes a number of configurable attributes as seen here Camel JMS Component . As soon as context is bootstrappe
