I like to (re)invent wheels. I am starting to like Unicode. Despite what others might say, I am not a Unicode expert. I have a personal website.

When I quote the C++ standard, I do it from a relatively up-to-date build of the sources at http://github.com/cplusplus/draft. (last build August 29th, 2012¹)

Trying to contact me? I usually hang out by the C++ Lounge. If you prefer e-mail, I sometimes check this mailinator mailbox: M8R-gt1qwe@mailinator.com.

¹ it will remain a bit out-of-date until I get my build machine set up again; meanwhile, you can get a more recent official draft, N3485.

Feb 6	comment	C++ vs D - Algorithm Optimization/Conversion (Using vectors/arrays) @Dr.Kameleon sorry, I only know C++ :) I would probably get rid of log2, but from there I have no idea.
Feb 6	comment	C++ vs D - Algorithm Optimization/Conversion (Using vectors/arrays) @Dr.Kameleon optimisations in the code are a pointless exercise if you request of the compiler to make a slow program.
Feb 6	comment	C++ vs D - Algorithm Optimization/Conversion (Using vectors/arrays) What further optimisations? What about... `-O3`?
Jan 26	comment	Naive C++ Matrix Multiplication 100 times slower than BLAS? And two threads.
Jan 26	comment	Naive C++ Matrix Multiplication 100 times slower than BLAS? "I believe both are using only a single core." There is no way the BLAS version is using only one core: note how CPU time is about twice as much as wall clock time.

Aug 19	comment	C++ My matrix class Yeah, that looks good.
Aug 17	comment	C++ My matrix class @R.M. obviously feel free to disregard the parts about iterators right until you start understanding them. If you decide to get on with and have trouble I'll be happy to help you with it on Stack Overflow or giving advice here :)

Aug 8	comment	C++ shared_singleton Konrad mentioned that someone in the C++ chat had some other solution. That was me: gist.github.com/3284629. However that solution doesn't allow for reinitialization, which you seem to desire. To be honest, the way it is now, this looks like a nice question for StackOverflow instead.

Jun 26	comment	Thread-safe singleton class using std::shared_ptr in C++(11) This is off-topic. codereview.SE is for working code. This doesn't even compile.

Jun 22	comment	Checking if a string is a number with STL It's not elegant if it has code for special cases (that's part of my definition of elegant).
Apr 20	comment	Edit Distance Between Two Strings @user1131467 No, it's not only a problem when you do that. It's also a problem when you forget to `using namespace phoronix` and now you're inadvertedly using `std::ref` when you meant `phoronix::ref`, but the compiler doesn't help you in the slightest there. It's also a problem when ADL picks up the wrong things because you never intended for ADL to be doing anything here. Wrapping an `#include` in a namespace is also a bad idea that will probably lead to linker errors down the line.
