A blog of my programming experience
I started building my own website in 2008 when I was still in secondary school using PHP and (X)HTML. At that time, the PHP version was only 5.2, without modern features like namespaces, late static bindings, closures, type safety, etc. There was…
After my previous post about static members in various programming language, I decide to write a post about the word static in depth. static is a key word in multiple programming languages, with multiple distinct but related meanings. The history The static…

As my programming experience begins to diverse, from traditional command-line programs to web and app development, I have used many programming languages, some of which I like, and some I don’t like. One particular aspect of programming languages, type system, contributes to…
I completed the he.net IPv6 Sage certification in January this year and have just received the T-shirt. I started the certification programme in 2011 when I upgraded my network infrastructure to properly support IPv6. I did all the way through guru, but…
Mobile computing is the trend, but due to the very different nature between a traditional desktop computer and a mobile device, the process models of desktop OSes and mobile OSes are also different. Traditional desktops are operated through a keyboard and a…

In C++, polymorphism does not take place within constructors: #include <iostream> using namespace std; struct Base { Base() { foo(); } virtual ~Base() {} virtual void foo() { cout << “Base::foo()\n”; } }; struct Derived : Base { void foo() { cout…
