C Code On GitHub Has the Most "Ugly Hacks"
itwbennett writes: An analysis of GitHub data shows that C developers are creating the most ugly hacks — or are at least the most willing to admit to it. To answer the question of which programming language produces the most ugly hacks, ITworld's Phil Johnson first used the search feature on GitHub, looking for code files that contained the string 'ugly hack'. In that case, C comes up first by a wide margin, with over 181,000 code files containing that string. The rest of the top ten languages were PHP (79k files), JavaScript (38k), C++ (22k), Python (19k), Text (11k), Makefile (11k), HTML, (10k), Java (7k), and Perl (4k). Even when controlling for the number of repositories, C wins the ugly-hack-athon by a landslide, Johnson found.
It doesn't take into account that with Perl and PHP, "ugly hack" is implied.
