Puppet Dashboard 1.2 Manual
Puppet Dashboard Manual (Generated on July 01, 2013, from git revision 46784ac1656bd7b57fcfb51d0865ec7ff65533d9) Puppet Dashboard 1.2 Manual This is the manual for Puppet Dashboard 1.2. Overview Puppet Dashboard is a web interface for Puppet. It can view and analyze Puppet reports, assign Puppet classes and parameters to nodes, and view inventory data and backed-up file contents. Chapters Installing Dashboard Upgrading Dashboard Configuring Dashboard Maintaining Dashboard Using Dashboard Rake API Installing Puppet Dashboard This is a chapter of the Puppet Dashboard 1.2 manual. NAVIGATION Installing Dashboard Upgrading Dashboard Configuring Dashboard Maintaining Dashboard Using Dashboard Rake API Overview Puppet Dashboard is a Ruby on Rails web app that interfaces with Puppet. It will run on most modern Unix-like OSes (including Mac OS X and most Linux distributions), requires a certain amount of supporting infrastructure, and can be deployed and served in a variety of ways. Dashboardʼs web interface supports the following browsers: Chrome (current versions) Firefox 3.5 and higher Puppet Dashboard Manual • Puppet Dashboard 1.2 Manual 2/27 Safari 4 and higher Internet Explorer 8 and higher Installing, in Summary In outline, the steps to get Dashboard running are: Installing the external dependencies Installing the Dashboard code Configuring Dashboard Creating and configuring a MySQL database Testing that Dashboard is working Configuring Puppet Starting the delayed job worker processes Running Dashboard in a production-quality server After completing these tasks, Dashboardʼs main functionality will be on-line and working smoothly. You can then configure Dashboard further and enable optional features If you are trying to upgrade Puppet Dashboard instead of installing it from scratch, see the chapter of this manual on upgrading instead of reading further in this chapter. -

Ruby Performance. Tips, Tricks & Hacks Who am I? • Ezra Zygmuntowicz (zig-mun-tuv-itch) • Rubyist for 4 years • Engine Yard Founder and Architect • Blog: http://brainspl.at Ruby is Slow Ruby is Slow?!? Well, yes and no. The Ruby Performance Dichotomy Framework Code VS Application Code Benchmarking: The only way to really know performance characteristics Profiling: Measure don’t guess. ruby-prof What is all this good for in real life? Merb Merb Like most useful code it started as a hack, Merb == Mongrel + Erb • No cgi.rb !! • Clean room implementation of ActionPack • Thread Safe with configurable Mutex Locks • Rails compatible REST routing • No Magic( well less anyway ;) • Did I mention no cgi.rb? • Fast! On average 2-4 times faster than rails Design Goals • Small core framework for the VC in MVC • ORM agnostic, use ActiveRecord, Sequel, DataMapper or roll your own db access. • Prefer simple code over magic code • Keep the stack traces short( I’m looking at you alias_method_chain) • Thread safe, reentrant code Merb Hello World No code is faster then no code • Simplicity and clarity trumps magic every time. • When in doubt leave it out. • Core framework to stay small and simple and easy to extend without gross hacks • Prefer plugins for non core functionality • Plugins can be gems Key Differences • No auto-render. The return value of your controller actions is what gets returned to client • Merb’s render method just returns a string, allowing for multiple renders and more flexibility • PartController’s allow for encapsualted applets without big performance cost Why not work on Rails instead of making a new framework? • Originally I was trying to optimize Rails and make it more thread safe. -

It is framework agnostic Three key technologies that are used for A custom HTTP 1.1 parser (based on RFC Mongrel's internals standard, written using Ragel in C and Java as a Rby extension) Simple server that uses the parser and URIClassifier to process requests, find the right handlers, then pass the results to the handler for processing Handlers are responsible for using HttpRequet and HttpResponse objects to "do their thing and then return results" Component of Mongrel responsible for Handlers dealing with HttpRequest and HttpResponse How does Mongrel support threading one thread per request, but it will start closing connections when it gets "overloaded"while Mongrel is processing HTTP requests and sending responses it uses Ruby's threading system What platforms that already work with Camping and Og+Nitro Mongrel are throught to be "thread-safe" Have not been heavily tested Is Ruby on Rails thread safe? no How does Mongrel handle Rails" " Ruby on Rails is not thread safe so there is a synchronized block around the calls to Dispatcher.dispatch. -
Rubabel: Wrapping Open Babel with Ruby Rob Smith1*, Ryan Williamson1, Dan Ventura1 and John T Prince2*
Smith et al. Journal of Cheminformatics 2013, 5:35 http://www.jcheminf.com/content/5/1/35 SOFTWARE Open Access Rubabel: wrapping open Babel with Ruby Rob Smith1*, Ryan Williamson1, Dan Ventura1 and John T Prince2* Abstract Background: The number and diversity of wrappers for chemoinformatic toolkits suggests the diverse needs of the chemoinformatic community. While existing chemoinformatics libraries provide a broad range of utilities, many chemoinformaticians find compiled language libraries intimidating, time-consuming, arcane, and verbose. Although high-level language wrappers have been implemented, more can be done to leverage the intuitiveness of object-orientation, the paradigms of high-level languages, and the extensibility of languages such as Ruby. We introduce Rubabel, an intuitive, object-oriented suite of functionality that substantially increases the accessibily of the tools in the Open Babel chemoinformatics library. Results: Rubabel requires fewer lines of code than any other actively developed wrapper, providing better object organization and navigation, and more intuitive object behavior than extant solutions. Moreover, Rubabel provides a convenient interface to the many extensions currently available in Ruby, greatly streamlining otherwise onerous tasks such as creating web applications that serve up Rubabel functionality. Conclusions: Rubabel is powerful, intuitive, concise, freely available, cross-platform, and easy to install. We expect it to be a platform of choice for new users, Ruby users, and some users of current solutions. Keywords: Chemoinformatics, Open Babel, Ruby Background tasks. Though it allows the user to access the functionality Despite the fact that chemoinformatics tools have been of the component libraries from one Python script, Cin- developed since the late 1990s [1], the field has yet to fony does not automatically manage underlying data types rally in support of a single library. -
