Bryan Cantrill seems to have some personal interest in denigrating OS research (defined as virtually everything post-Unix) as all being part of a misguided &quot;anti-Unix Dark Ages of Operating Systems&quot;. He has expressed this sentiment multiple times before, and places a great deal of faith on Unix being a timeless edifice which needs only renovation. Naturally, he regards DTrace and MDB to be the pinnacles of OS design in the past 20 years and never stops yapping on about them, this article being no exception. It&#x27;s his thought-terminating cliche.<p>He voiced all this here [1], and so I countered by listing stuck paradigms in traditional monolithic Unixes, as well as reopening my inquiry on Sun&#x27;s Spring research system, which he seems to scoff at, but over which I am impressed by the academic research it yielded. He has yet to respond to my challenge.<p>[1] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10324211" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10324211</a>
