In my experience, the only people who weigh in on these debates are those who do not live in Silicon Valley -- like any epicenter for anything, those of us who have made our careers here hardly give a damn how the rest of the world compares

My blog entry explains some of the technical background of this launch, with links to much more in depth material from both me and other Joyent engineers: http://dtrace.org/blogs/bmc/2011/09/15/standing-up-smartdatacenter/

The definition of a derived work is actually much more crisp than you are making it out to be -- and it is simple fact (and not opinion) that illumos is not a derived work of our KVM module. Indeed, this issue is so clear-cut and your objec

Actually, our port does not use these hooks -- there were zero mods to the illumos kernel to support KVM per se.

No; the KVM kernel module is in its own repo: https://github.com/joyent/illumos-kvm

There is not a licensing issue here: both KVM and our KVM port remain licensed under the GPL.

Could you be more specific? It's there, it works, it's in shipping illumos-based products (from Joyent and others) and it's supported by those who ship it or stand it up. In that regard, it's like any other aspect of the system...

KVM was ported to illumos by Max Bruning, Robert Mustacchi and me. Details are here: http://t.co/knW1UIJ

Agreed, and I've piled on here: http://bit.ly/plxCb1 . Or have we both been trolled?

I don't indulge in the SUNW autopsy parlor game often, but coincidentally, I've already played it twice today (for the first time in many months), and I'm waiting on a build -- so perhaps the third time's a charm... Disclaimer: I was one of

Were it only that simple! No, "engaging with the ACM" means becoming involved via either local chapters or with the national organization -- and it starts with becoming a member. If you're curious about other ways to get involved, I'm happ

So, some disclaimers: I sit on the ACM's Professions Board, and am a member of the CACM Editorial Board, where I sit on the board for the Practice section of CACM, also known as ACM Queue. That said, I speak only for myself here, not for

More accurately, we (for there are many of us) realized that we could go solve much more interesting problems elsewhere -- and in a much better environment besides. Why would anyone wish to suffer at a technically mediocre company when the

Why is this news -- or even interesting? Perhaps assembly feels exotic to a dilettante, but to anyone with a computer science degree this was simply a part (and an early and basic part) of their education...

Loved having you guys in the competition! I could always rely on you to light up Alaska on the NodeKO leaderboard at http://leaderboard.no.de !

DTrace is in fine shape -- Oracle has monopoly over neither DTrace talent nor implementation. (And the significant patent portfolio around DTrace is licensed to anyone who abides by the CDDL -- and the name itself is not trademarked.) ZFS

You are missing an important motivator of great engineers: we seek out hard, commercially-relevant problems of course, but these problems must also be societally relevant and responsible. While our actions may often reflect it only implic
