I wrote a simple program that generates a random word 10,000,000 times.
I wrote it in python, then in C++ and compared the two completion times. The python script was faster! Is that normal? Why would the python script be faster? I was under the impression that C++ was faster. What are some of... (2 Replies)

INTRO(9) BSD Kernel Developer's Manual INTRO(9) NAME
intro -- introduction to system kernel interfaces DESCRIPTION
This section contains information about the interfaces and subroutines in the kernel. PROTOTYPES ANSI-C AND ALL THAT Yes please. We would like all code to be fully prototyped. If your code compiles cleanly with cc -Wall we would feel happy about it. It is important to understand that this is not a question of just shutting up cc, it is a question about avoiding the things it complains about. To put it bluntly, do not hide the problem by casting and other obfuscating practices, solve the problem. INDENTATION AND STYLE
Believe it or not, there actually exists a guide for indentation and style. It is not generally applied though. We would appreciate if people would pay attention to it, and at least not violate it blatantly. We do not mind it too badly if you have your own style, but please make sure we can read it too. Please take time to read style(9) for more information. NAMING THINGS
Some general rules exist: 1. If a function is meant as a debugging aid in DDB, it should be enclosed in #ifdef DDB #endif /* DDB */ And the name of the procedure should start with the prefix DDB_ to clearly identify the procedure as a debugger routine. SCOPE OF SYMBOLS
It is important to carefully consider the scope of symbols in the kernel. The default is to make everything static, unless some reason requires the opposite. There are several reasons for this policy, the main one is that the kernel is one monolithic name-space, and pollution is not a good idea here either. For device drivers and other modules that do not add new internal interfaces to the kernel, the entire source should be in one file if possi- ble. That way all symbols can be made static. If for some reason a module is split over multiple source files, then try to split the module along some major fault-line and consider using the number of global symbols as your guide. The fewer the better. SEE ALSO
