For example for the pidigits bench:
The PHP version use the GM extension http://shootout.alioth.debian.org/u64q/program.php?test=pidi...
And Ruby do it in pure Ruby http://shootout.alioth.debian.org/u64q/program.php?test=pidi...
So basically it's a C vs Ruby benchmark. Many peoples complained on the forum, take a look.
The Debian shootout is interesting, but don't take it as an absolute truth.
Please show where I said that, or admit that you are putting words into my mouth.

If you believe the shootout results can reliably show that one language is faster than another, say so. Otherwise, de facto you are saying you cant rely on the results.

Your words -- not mine.
I'm stopping this dance here. Feel free to make a claim about the reliability of the results, and whether you can use them to say that one language is faster than another. Then we can dance some more, but otherwise I'm out.
> Feel free to make a claim...
The only point of "this dance" was to help people understand that you are putting words into my mouth.
Please say what you mean by "a language is faster than another".
Please say what in The Java™ Language Specification tells us that "language is faster than another."
(That's the context of the conversation, see http://news.ycombinator.com/item?id=4851781)
That's a different claim.
>> It doesn't even make sense <<
That depends on what `notJim` meant by "to compare speeds of programming languages".
`notJim` might have thought that everyone would understand he was talking about particular language implementations and particular tasks and particular programs.
The pi-digits page also shows a PHP program which does not use the GMP extension.
Why do you think no one has contributed a Ruby program that uses GMP? Is that too hard to do using Ruby?
The benchmarks game is the absolute truth about the reported measurements.
