All: there was a big thread about this yesterday (https://news.ycombinator.com/item?id=23285249) but because it didn't focus on the technical content, and because there were glitches with a previous submission of this report (described at https://news.ycombinator.com/item?id=23288120 and https://news.ycombinator.com/item?id=23287763 if anyone cares), we invited aphyr to repost this. Normally we downweight follow-up posts that have such close overlap with a recent discussion (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...), so the exception is probably worth explaining.
