On Bruno’s Concern About the Current Coupling of node.js and V8

Bruno Fernandez-Ruiz (Yahoo! Fellow, VP and Platform Architect) wrote about his concerns around the current tight coupling between node.js and V8. Feel free to take a moment and read the original article: “NodeJS: To V8 or not to V8”.

A reply doesn’t fit into a twitter response, and an update mentioning my reply would be great.

Overall, it’s a valid concern, partially enforced by the fact that we’ve left the github page titled “Evented I/O for V8 javascript”. We have debated this internally and have intended to correct it. It is also currently true: Node.js is only implemented on V8 but that’s only because we’re going to focus on making node.js awesome first.

I haven’t had a chance to meet Bruno, we’ve only exchanged a couple of emails in the past. Bruno forgot or doesn’t know a couple of key things about node.js and Joyent. I’m always happy to talk about development process at Joyent.

Because I actually have answers to his questions, comments and concerns, I’m going to reply below. They are trimmed down and if I’ve missed one in particular, please let me know in the comments.

Update: Bruno took the time to follow-up with responses to my queries, while former Yahoo Principal Engineer (and current “Desperado at Facebook“) Peter Greiss has waded into the debate as well.

Oracle and OpenSolaris: A Kernel of Truth

@nevali on Twitter asked a question that we’ve heard from many customers, so I’m writing a response to everyone, though none of you need to worry. His question is, “As a long time Open Solaris stalwart, I do wonder what @Joyent’s perspective on the post-Oracle-takeover world is.”

In many ways, we’re happy to have seen Oracle and Sun combine. Sun was a great company for technologists and Oracle is tremendously good at operating a business. Oracle may prove to be the management team that can turn around Sun’s fortunes. And I think they’re completely committed to the Solaris kernel.

A lot of people think of OpenSolaris™ when they think of Joyent, and that’s reasonable — since it’s the most well known open source distribution of the Solaris Kernel. But in truth, Joyent has never used OpenSolaris™. OpenSolaris™ is a full operating system, a “distribution” containing both a kernel and a userland (along with packaging tools), the name a marketing term used to refer to this full distribution. There are a number of features in there that we’ve simply never cared about: For instance, we have no need to allow laptops to sleep. Since 2005, Joyent has been using the open source Solaris 11 kernel, a couple of binary bits and combining it with a Solaris build (that we maintain) of NetBSD’s pkgsrc. Combining a BSD set of tools with the rock solid Solaris gave us a foundation that contained the best of both worlds and allowed us to have a functional userland while having access to DTrace, ZFS and Zones.

So given Oracle’s commitment to the Solaris kernel, and the way we’re using it in SmartOS, we’re actually very well aligned with Oracle. Also, we’ve been working and will continue to work to make our base operating system a completely open operating system, and we are aligned with and believe in the vision behind the Illumos project.

If you have any particular questions, comments or concerns in this area, please feel free to let me know directly at jason@joyent.com and I’ll make sure they get addressed.
