http://250bpm.com/blog:4 and http://250bpm.com/blog:8 give some reasons.

For doing GUI or anything not time critical, hey, you can use Java or Javascript or whatever language you want, but if performance is the primary goal (without CPU dependency), then C is clearly the answer. If CPU dependency is ok, then assembler

Last I checked, mining fell into the "performance is everything" category

please no C++ is gods gift to programming stuff and I know c++ can compile C code and has all sorts of wonderful classes for everything. I just never liked classes.

If anybody seriously believes that an optimized C miner wont be faster than a C++ one, then let us make some wager
