Similar to GitHub, Bitbucket makes it very easy to host your code. We all know that GitHub works great for open-source. However, you have to pay if you want to create private repositories. On the other hand, Bitbucket enables you to create unlimited free private repositories. This is an important reason why more and more people are using Bitbucket nowadays. In this post, I will show how to use Bitbucket to easily host your code (over TortoiseHg specifically).

A text file can be encoded in many different character encodings. There are many encoding variations even just for Windows system. Special attention has to be given when handling text files with different character encodings, e.g. if we use fstream‘s getline() to read from a text file (contains Chinese) in UTF-8, we will get gibberish characters, while will be correct if the text file is in ANSI.

In this post, given a text file, I will show how to get its character encoding and how to convert it from one character encoding to another.

Boost is a set of libraries for the C++ programming language that provide support for tasks and structures such as linear algebra, pseudorandom number generation, multithreading, image processing, regular expressions, and unit testing. Steps to build Boost for x32/x64 VC++ compilers on Windows are as follows:

Weird things often occur in programming. We can tell so-called reasons to some of them. For others, the only thing we can do is, how the hell could these be? We have to pay extra attention to avoid these in order not to fall into debugging nightmares.

In previous post, I talked about how to use Libxml2 library to read/write xml files. Actually, there are many Free C or C++ XML Parser Libraries. From now no, I will turn to MSXML instead because of Libxml2’s poor support for Windows-x64 systems.

In the followings, I will show how to use MSXML to read/write xml files.

Libxml2 is the XML C parser and toolkit developed for the Gnome project (but usable outside of the Gnome platform), it is free software available under the MIT License. We can use it to read/write data from XML data file.
