I don't have a reduced test case.

I used dmd. i sometimes got the feeling that you underestimate the sheer power of todays clang or gcc optimizers - so partly what gdc/ldc can do with your code reminds me of brian schotts exmaple of his sse2 optimized version of his lexer - the dmd generated was much faster then the normal version, but gdc/ldc results of the unoptimized versions are still 50% faster i understand your focus on dmd - but talking about fast code and optimizing WITHOUT even trying to compare with other compiler results is just a little bit strange for someone who stated speed = money I think this somewhat misses the point of the example, which I would say was - in academia-speak - purely illustrative. The point still stands, which is "unless you understand the compiler and the architecture, stop trying to second guess performance on the micro-level"

I've added an indirect link to my awesome-d github page where your book is listed: https://github.com/zhaopuming/awesome-d#books But don't know whether that would be filtered also.

I think reddit's silent spam filter dislikes the link. I can tell them to search the web for it though. i don't know how many times you tried but when i searched the url on reddit it found 3 results. one of them was http://www.reddit.com/r/programming/comments/26pn00/d_cookbook_officially_published_consists_of_d/ which is a post by you.

Yeah, the top level post seems to work, but comments on other posts, including this one, don't show up. The indirect link plan appears to work though.

Re: DConf 2014: Adam D Ruppe's amazing slideless talk on x86 Bare Metal and Custom Runtime Programming
Plain text transcript of the video (typed up by me, so there may be some errors but the bulk of it should be readable) http://arsdnet.net/dconf-transcript.txt I'll do an annotated HTML version when my schedule permits but for now you can look at the plain text file there (if you don't see it all, try refreshing because you might have last night's version cached) if you want something searchable or don't like videos. I randomly made notes of the timestamp as I typed it up so you can jump to it in the vid too. But, since for the most part it was just me pacing and talking, except for a few points where I used my fingers to illustrate points, you aren't really missing that much sticking to plain text (except for transcription errors). I'll post the annotated version when it is done here too.
