Basic Knowledge of Cygwin

Posted on May 6, 2009 by Icyfish

Cygwin is a Linux-like environment for Windows. It is something like a Linux simulator, but actually it is NOT. Cygwin is not a way to run native linux apps on Windows. You have to rebuild your application from source if you want it to run on Windows. Cygwin is not a way to magically make native Windows apps aware of UNIX ® functionality, like signals, ptys, etc. Again, you need to build your apps from source if you want to take advantage of Cygwin functionality.

Because it is simple to use and you don’t need to install a real Linux on your computer, it is widely used for Windows user. The most common situation to use Cygwin is when you want to use g++ in Windows. Continue reading →

Further study on duplicate elements of HashSet

Posted on April 22, 2009 by Icyfish

In mathematics, it is trivial to check duplicate elements because the properties of an element are simple. It may just contain numbers, letters, and colors and so on. However, it is complicated to check whether two elements (objects) are the “same” in computer programming.
In Java language, the Set interface is defined as “A collection that contains no duplicate elements. More formally, sets contain no pair of elements e1 and e2 such that e1.equals(e2), and at most one null element”. The HashSet class implements the Set interface. How does it check? Does it really use equals method? Let’s have a look. Continue reading →

Build up C/C++ environment on eclipse using CDT + cygwin

Posted on April 20, 2009 by Icyfish

More and more people want to use open source IDE instead of Visual Studio to writing C/C++ because it’s clean and free. Here, we introduce eclipse to writing C/C++ program. Eclipse is an excellent IDE for Java programming. Due to its open source platform, we may use it for C/C++ programming as well. CDT(C/C++ Development Tool) is a plugin that allows eclipse to support C/C++. Cygwin is a Linux-like environment for Windows and it allows you to use gcc/g++ compiler. There’re just several steps to build up your own eclipse. Now, let’s go. Continue reading →
