• We'd need a vendor neutral repo
• But maybe also are to add vendor repo (like ubuntu one, chef one) where every owns their set/part of the template, like plugins you can load
• I imagine the templates writing in a coding-neutral way (think moustache based templates)
• have them shared as gems, npm, etc.. packages for usage in each ecosystem
• provide a library that can generate (using vars/context) the templates you need (much like erb templates)
• these libraries can be easily written in each language ecosystem to generate templates
• so f.i. bento can use a gem to generate the templates specific with chef only in their repo
• besides the use as a library it should have a cli tool that can create these templates
• we can consider something like the homebrew system to store the templates in
• I think templates could benefit from meta-info that describe the vars that someone is able to set when generating a template

@datadoghq - Overall well done! Here's some feedback:

Signup/User process

• when someone invites you to their datadog/team, you get an email but because you are already registered you can't join their team. Especially annoying for freelancers that work for multiple customers but don't have an email account at the customer site
• disable a user is scary (will this delete it, can I re-create it?); a warning or ? next to it would help for fast understanding
• if the user you invite does not have it's gmail activated yet (google for apps), when the email is added it's send out (but doesn't reach it of course). There is no way of re-sending the invite from the admin side
• the forcing of registering at least one agent/integration is really annoying. if you signup through an ipad or the person signing up (like billing) does not have any way to go past that screen. So you wonder , am I registered or not? In our case the person installed the mac agent from it's laptop to get it going. No need for that imho

Dysfunctional organizations are often associated with being experts at the game of 'ping-pong': pushing work to the other, passing the blame to others...

In the heat of the 'battle' there is often high-volume of exchange of information. But what makes this an unpleasant experience vs. the high-volume exchange of ideas?

Given the same feedback , with a different level of trust , the context changes. Game-theory shows that it can be applied to Politics, Organizational change or Personal things: Even when we know things are good for us, we might not do them because we don't trust our peers.

This presentation will show how both Trust and Feedback are embedded in many of the #devops related concepts, both at the process, cultural level but also at the tools level. What makes a 'good' devops tool, process? How they drive the building of Trust and how they depend on trust? How this affect your daily life as a developer, operations , qa , security or any other part of the company.

Understanding this relationship

• Ask the Ignite presenters to send the slides upfront

  • An option is to use a Dropbox shared directory

• Be prepared to run around with USB stick to get the 'on the spot' deciders.

• PDF is the easiest format

• You can run either :

  • impress -a 15 http://impressive.sourceforge.net/
  • adobe acrobat reader in autoadavance mode http://malektips.com/adobe_reader_7_0019.html

• Don't let them run on their own laptops

• Use a dedicated laptop (avoid any popups etc...)

Title:

How to make operations love Nodejs Apps

One little typo for Dev-kind, one big failure for Ops

(or vice versa if that makes more sense)

Abstract:

One little typo, is all what it takes to break a nodejs program. From an operational side, this doesn't give you much confidence.

Much of the documentation on nodejs out there is focused on building websites with Express and the Secret Sauce 'Socket.IO' and friends. Documentation on non-functional aspects, is sparse and more fragmented.

Clustering: The basics

The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)

It does not balance, it leaves it to the kernel.

In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)

• http://nodejs.org/api/cluster.html
• Simple cluster example:
