I鈥檓 pretty bored today, and I wanna take a break from learning Python. So, I decided to compile an open source game, LBreakOut (L is for Linux), for my PowerBook. In order to compile this game, you need obviously the source code of the game where you can get it from here. Additionally, you need the SDL library, where you can get it from http://www.libsdl.org. Here is the screen-shot of game running on my PowerBook: ...
Normally, I would bunzip the file first, then untar it next. But I found something after googling for a shortcut: it can all be done with just one tar command. $ tar -xjvf example.tar.bz2 Notice that, we use j flag to decompress bzip2 file and z flag for gzip file. 馃檪
I just learned how to implement basic command-line argument with Python. Hence, I would like to incoporate this feature in the previous Temperature Conversion program. # convertc2f.py # Version: 0.2 # A program to convert Celsius temps to Fahrenheit # Date: 4/13/06 # by: S. San (Kenno)` import sys if (len(sys.argv) == 2): celsius = int(sys.argv[1]) else: celsius = int(input("What is the Celsius temperature? ")) fahrenheit = 9.0 / 5.0 * celsius + 32 print("The temparature is", fahrenheit, "degrees Fahrenheit.") Example with the command line argument: ...
Mac OS X Tiger still uses the J2SE 1.4 as default Java virtual machine and compiler. If you need to upgrade to JDK 5, you have to download it from Apple download site. After you install it, you need to change a symlink to point to the JDK 5: $ cd /System/Library/Frameworks/JavaVM.framework/Versions/<br /> $ sudo mv Current Current.old<br /> $ ln -s 1.5 Current<br /> $ mv CurrentJDK CurrentJDK.old<br /> $ ln -s 1.5 CurrentJDK ...
If you get used to read the temperature in Fahrenheit scale like me, you may be confusing to see the temperature in Celsius scale given in weather forcasting on Australian or New Zealand televisions. So today, I鈥檓 gonna share a small Python program which can be used to convert the temperature scale from Fahrenheit to Celsius. As my Python programming skill is very limited at the moment, the program is going to perform very basic function. ...
