Software diseases: memset
Andrey Karpov7/23/2012 7:58 AM EDT
While analyzing the source codes of various programs I can't help creating associations that each program has a tendency to certain diseases. In many projects you can easily make out patterns of incorrect code that can be found in different project files. In some programs these are Copy-Paste errors, while in others it's "unsigned_integer less 0"-like checks. Each project has its own disease. The sore of the next project (called MAME) we have checked is the memset() function.

Great article, and wonder if any future code analysis can be embeded in IDEs or compilers to assist for improved programming results from begineer and itermediate skilled programmers.
Although, bad programming can be generated by abscent minded individuals, as well as automation directed by the wrong person.

Bad code is generated by lazy (and arguably incompetent) coders who fail to read and understand the manual page(s) for the library routines they misuse. The article appears to complain about the routines, not the coders inability to use the functions correctly.

For those lucky enough to have access to a Unix/Linux/POSIX environment,
man 3 memset
man 3 memcpy
