Understanding Job-Skill Relationships Using Big Data and Neural Networks

TEC-57 – Full Stack Ruby-On-Rails Web Developer Certificate Program with Externship
Continuing Education 1717 S. Chestnut Ave. Fresno, CA 93702-4709 (800) 372-5505 https://ce.fresno.edu TEC-57 – Full Stack Ruby-on-Rails Web Developer Certificate Program with Externship Professional Education Course Syllabus Program includes National Certification & an Externship Opportunity Course Contact Hours: 42 The Full Stack Web Developer Profession Full stack developers are software or website programmers who combine the roles of front-end and back-end developers. Stack developer job is relatively new (just four years old). This role blends both front-end and back-end development since there is no clear borderline between the two: front- end developers often lack extra back-end skills, and the other way around. Full stack duties, in their turn, unite the both. These specialists work professionally both on the user side and server side of the web development cycle. To this end, the role requires in-depth knowledge of every level of web creation process, which includes Linus server’s set-up and configuration, creating server-side APIs, making JavaScript-codes that power apps, and so on. A Ruby on Rails developer is responsible for writing server-side web application logic in Ruby, around the framework Rails. Ruby on Rails developers usually develop back-end components, connect the application with the other (often third-party) web services, and support the front-end developers by integrating their work with the application. Ruby on Rails, as a framework, has gained popularity tremendously over a very short period of time. The goal of the framework is to reduce the time and effort required to build a web application. -

Introduction Who I am What I'm here to talk about 2 Copyright © 2010, Netomata, Inc. All Rights Reserved. Why automate network configuration? Because automated networks are More reliable Easier to maintain Easier to scale 3 Copyright © 2010, Netomata, Inc. All Rights Reserved. For example... Imagine you're managing a moderately complex web site Multiple real and virtual hosts Several "environments" (production, testing, development, etc.) Separate VLAN for each environment 4 Copyright © 2010, Netomata, Inc. All Rights Reserved. For example... What networking devices & services need to be managed? Routers Switches Load Balancers Firewalls Real-time status monitoring (i.e., Nagios) Long-term usage monitoring (i.e., MRTG) 5 Copyright © 2010, Netomata, Inc. All Rights Reserved. For example... How to add new virtual host to existing load balancer pool? Set up host itself, using Puppet or cfengine or whatever Add host to VLAN defs on switches Add host to ACLs on routers Add host to pool on load balancers Add host to NAT and ACLs on firewalls Add host to real-time monitoring (i.e., Nagios) Add host to usage monitoring (i.e., MRTG) 6 Copyright © 2010, Netomata, Inc. All Rights Reserved. For example... What's the problem with doing all that by hand? You have to remember how to manage all those very different devices (and you probably don't do it very often) It takes a lot of time Every step is a chance to make a mistake You might get distracted, and never finish Over time, these small mistakes add up, leading to inconsistent networks that are unreliable and difficult to troubleshoot 7 Copyright © 2010, Netomata, Inc. -
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. -

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.
