I make software and sometimes other things.

 

Due to Blogger's termination of support for FTP, this blog is no longer active.

It is possible that some links from here, particularly those within the site, are now broken. If you encounter one of those, your best bet is to go to the new front page and hunt for it from there.

Most, but not all, of the blog's posts are on this page; the archives are here.

 
Recently I wrote some code in which a templatized class declared one of its template parameters a friend. This worked fine in Visual C++, and I was surprised to find that GCC gave the rather unambiguous error, Template parameters cannot be friends. I was even more surprised to find that, indeed, this is not GCC being overly picky - it is not legal C++! There are extremely crufty workarounds, but in general it's clearly a bad idea to rely on platform-specific violations of the C++ standard in production code.
