Study Notes

  • Carles Mateu: carlesm.com
  • Web 1.0 is characterized by Read-Only (R/O) capabilities
  • Web 2.0 is characterized by Read/Write (R/W) capabilities
  • Focus Change in the Web shifts the philosophy, technology and social aspects
  • Philosophy changes from individual focus to collective focus
  • Technology enables reuse, sharing, remixing, and rewriting
  • Social aspect evolves from reader-consumers to creators-producers

Web 2.0

  • Key features include simplicity, usability, and a focus on user experience
  • It involves wikis, folksonomy, recommendations, and social software
  • Blogs play a significant role
  • Key web 2.0 features includes participation, convergence, and remixability
  • It emphasizes data-driven approaches with open APIs
  • Standardization, separation of form and content, and the use of microformats are important
  • The Web enhances user interaction through "rich" interfaces
  • Folksonomies serve as a method for users to classify information through tagging
  • Software is based on communication and community building
  • Social networks connect individuals with shared interests or business relationships
  • Social bookmarking allows users to save and categorize their favorite pages

Additional Web 2.0 Information

  • Lightweight business models with small, focused teams and clear income streams are important in attention economy
  • User-generated content drives new services
  • Transparency and openness are beneficial
  • Making things fun enhances user engagement
  • The Web is a platform where services are accessible from anywhere
  • AJAX enhances user interaction by updating web pages without reloads

Web Application Design Principles

  • Multiple technologies can be used together
  • Includes: ATOM, JSON, XHTML, AJAX, CSS, XML, and JavaScript
  • Data and presentation should be separated
  • This involves managing data separately from presentation
  • Scripting can be used on both the server-side and client-side
  • Existing APIs ease data access and protect from design changes

Optimizing Web Application Performance

  • Reduce page load time by retrieving only essential data
  • Be aware of the impact of scripting on clients
  • Takes into account performance, battery usage, time etc.
  • Consider users with low connection speeds and non-desktop devices.
  • Search engines may not properly index text inside images, Flash, videos, or dynamic pages, which affects visibility
  • Object-Oriented Programming (OOP) techniques should be employed
  • Includes using objects with defined behaviors and states
  • There should be design before programming
  • Choosing the right languages/tools is crucial

Web development guidelines

  • Making it usable and reusable is important
  • Follow existing standards instead of reinventing the wheel
  • Investigate and learn similar technologies
  • Google Maps have API for mapping services with 1468 mashups
  • Flickr API for photo sharing service with 350 mashups
  • YouTube API for video sharing and search with 271 mashups
  • Amazon eCommerce API for online retailer with 248 mashups

12 Factor App Methodology

  • Codebase: one codebase tracked in revision control, many deploys
  • Dependencies: explicitly declare and isolate dependencies
  • Config: store config in the environment
  • Backing Services: treat backing services as attached resources
  • Build, release, run: strictly separate build and run stages
  • Processes: execute the app as one or more stateless processes
  • Port binding: export services via port binding
  • Concurrency: scale out via the process model
  • Disposability: maximize robustness with fast startup and graceful shutdown
  • Dev/prod parity: keep development, staging, and production as similar as possible
  • Logs: treat logs as event streams
  • Admin processes: run admin/management tasks as one-off processes
