A blog of my programming experience
In the past, about the years I was in sixth-form and first-year university, I used KOrganizer for my calendars, which is the first calendar software that I use, in conjunction with Kontact. I love KOrganizer. It is feature-rich. It allows me to…
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…

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…
The size of an item in computer displays or printouts depends on a lot of configurations. Font size, DPI/PPI, screen resolution, page zooming, etc. all contribute to the output size. Font sizes are traditionally measured in points, which are used in typography…
I have just realised that I haven’t written a post yet since I successfully entered HKU to study BBA(IS). I’m very happy that I can finally study computer science in university! The subject that I love most! Although I haven’t made much…
After setting up IPv6 for nearly two months, I’m now interested in testing an IPv6 only LAN. In order to access the IPv4 Internet from an IPv6 only network, a method called NAT64 is used. It is an address only translation method…
I’ve just set up a free tunnel from Hurricane Electric. I can now visit the IPv6 Google site http://ipv6.google.com/
