In this event, we will dive deeper into the stack components, and we’re bringing some familiar Node.js faces into the mix. Up first will be a tag-team presentation by Isaac Schlueter and Charlie Robbins, who each provide us with an update on 0.10 and also review the future of Node.js. We are also bringing back some fan favorites including both Aaron Heckman from 10Gen and Nuno Job from Nodejitsu, to keep diving into MongoDB, Node.js and SmartOS.
Date: Tuesday, June 18, 2013 10:00 AM – 11:00 AM PDT
In this event, we will go beyond the theory and talk about production use of Nodestack from various angles of the stack. Up first will be Jason Hoffman, CTO at Joyent, who will talk about the long history of using Node.js in production at Joyent. From there, we will have Paul Serby from Clock talk about bringing the front and backends together for the optimal production user experience. Last but not least will be Will Shulman, CEO of MongoLab, reviewing their deep experience running MondoDB in the cloud.
Bruning Questions: What is ipdadm(1M) Used For? – “a tool that he wrote that allows one to simulate network problems. The tool is ipdadm(1M), the internet packet disturber. The tool allows you to specify as a percentage: packet drops, packet corruption, and delays. This can be very useful when you want to test the effect of these on the behavior of a networked application.” – Max Bruning
Eric Saxby of Wanelo at ChefConf: ”Why should I care? Because lower latency = less cost.”

Bruning Questions: Why Take Joyent Training? “About training that Joyent offers, and how we do training differently from what a lot of people have come to expect from corporate training.” – Max Bruning

Bruning Questions: Why Use SmartOS? – In which Max Bruning answers: “So, why would you want to use SmartMachines or SmartOS as opposed to Linux?”
the #zfs / #illumos / #smartos community is truly awesome … had wondered about weird dedup behaviour and they came right to my rescue

A New Versioning Scheme for SmartOS Images and an Updated Base Image – “Our old versioning scheme for SmartOS images was a bit confusing, and it wasn’t obvious what pkgsrc version a given image was built on.” – Christopher Horrell, Joyent

A Smarter OS - video: Joyent’s Ben Rockwood and Blake Irvin and Eric Saxby of Wanelo talk SmartOS on the Foodfight show. With special guest appearance by Bryan Horstmann-Allen of SourceFire. Why do these folks love and use SmartOS? DTrace, SMF, ZFS…? Let them count the ways!
Technical Videos – “An up-to-date listing of nearly 400 technical videos I have been involved in, one way or another, in the six years I’ve been working with Solaris, illumos, SmartOS, and related people, technologies, and companies. They are listed in reverse chron order by date of the event…” Deirdré Straughan

“Startup Pluribus Networks is proposing a top-of-rack server/switch combination that can run applications, provide storage and provision services like DNS, DHCP, load balancing, firewalls, analytics and packet capture. Through the company’s operating system and hypervisor software, two or more of these server/switch combinations can create a large, virtual data center fabric with network virtualization and software-based control with a variety of proprietary and standard APIs.” – Jim Duffy, Network World. Why is this on the SmartOS blog? Because one of the company’s founders is Sunay Tripathi, the father of the Crossbow network virtualization technology that’s in SmartOS.

Bruning Questions: ZFS Record Size - “”I thought ZFS record size is variable: by default it’s 128K, but write 2KB of data (assuming nothing else writes), then only 2KB writes to disk (excluding metadata). What does record size actually enforce?” – Max Bruning answers this question!

This course introduces DTrace and teaches common performance analysis techniques. It is intended for system support staff, system administrators, developers, and anyone who would like to quickly learn DTrace and some practical methods for applying it. This course teaches core features of DTrace that are available in many enterprise and cloud computing environments, and is taught from a Joyent SmartMachine, a restricted environment that provides these features. Kernel internal analysis is not covered. (An advanced course for kernel-level DTrace is planned in the future.)
This course makes extensive use of labs, where performance issues based on real-world cases are simulated in isolation for the students to solve, with help from the instructor. For some this is the highlight of the course, putting the methodologies learned into practice and seeing how they work first-hand.
cost: $2,250

Why SmartOS in my lab? – “I want an uncomplicated and fast route from CPU to storage with as few storage widgets between them as necessary. I want a compute/storage server that is as fast to set up as an iPhone. I want computational capability as close to my data as possible.” – Christopher Hogue
