Single Sign On in Ruby - Enterprise Ready!

Jun 1, 20124 likes4,961 views

The document discusses implementing single sign-on (SSO) for an enterprise using open standards. It evaluates several potential standards, including OpenID, OAuth, CAS, Shibboleth, and SAML, and recommends SAML 2.0 due to its support among major technology providers. RSAML is presented as a Ruby wrapper for SAML that provides most required functionality. The in-development "Russo" project is described as a Rails engine that implements SAML 2.0 via RSAML to enable SSO without requiring authentication logic within the application. Help is requested to finish RSAML, complete Russo, and add documentation.

Single Sign On
Enterprizzzey ready!

Nikos Dimitrakopoulos | @nikosd

Single Sign On (really)
● Centralized (almost) authentication
● Login once - be logged-in in multiple
services
● More than just "no password required"
● Single Log Out
● Actual "authenticator" can be an outsider
(Facebook, Twitter, or whatever...)

● Complex
● XML based
● (Unhappy face here...)

But :
● Really the only de-facto standard
● Implemented / supported by :
○ Google
○ Microsoft
○ Oracle
○ ...

○ Do it on the mounted app
○ Use OmniAuth!!!

Russo
● Status : Core functionality should be there
during this week
● Use cases : Pretty open since most of the
functionality is done on the mounted app
● Learning curve : Pretty high - understanding
SAML is required

Why this presentation???
Please help!!! :)

● Finish up RSAML
○ XML Signing
○ Unimplemented features

● Complete Russo
○ Single Log Out
○ Support for other use cases
○ Documentation

Web assembly overview by Mikhail SorokovskyValeriia Maliarenko

WebAssembly is a new binary format for the web that is fast, compact and provides near-native performance. It was developed by major browser vendors as a compilation target for programming languages like C/C++ to run on the web. WebAssembly has a small binary format, runs in any browser, and provides performance comparable to native code. It fills gaps in JavaScript for heavy computation tasks. The roadmap includes adding threads, shared memory and exception handling to WebAssembly.

Customize UI with ProtocolsPofat Tseng

Віталій Бобров — Web components, Polymer and DrupalLEDC 2016

Web Components allow the creation of reusable UI widgets using open web technologies like Shadow DOM, HTML Templates, and Custom Elements. The Web Components specification defines these technologies. Polymer makes it easier to build custom elements that work like standard elements through features like encapsulation, templating, and declarative data binding. In Drupal, the Web Components API module provides a polyfill for browser support and APIs for defining and loading components, while the Polymer API module handles loading the Polymer library and elements. Both modules welcome community contributions.

WebAssembly FundamentalsKnoldus Inc.

WebAssembly (Wasm) is a binary instruction format for a stack-based virtual machine that allows deployment of web and server applications. Wasm is not a transpiling target for JavaScript or a replacement for JS, but rather a compilation target for programming languages to enable deployment on the web. The key aspects of Wasm include its stack-based architecture, core data types like integers and floats, control flow constructs, and use of linear memory. WABT is a toolkit that helps manipulate Wasm files, allowing generation of text format (wat) from binary (wasm) and vice versa. Building a Wasm app involves understanding its architecture and using tools like WABT.

Headless Android at AnDevCon3Opersys inc.

Headless Android allows running the full Android system stack without any graphical user interface elements. This is done by disabling SurfaceFlinger, WindowManager and other UI services. The result is a smaller memory footprint but full access to Android services, APIs, and development tools. Key changes include tweaking internal calls to disable expectations of a graphical environment and starting components with 'am' instead of activities. This produces a streamlined Android configuration for embedded and automation use cases.
