Web Deployment Checklist: Release and Roll Back a Course App

-
Practical Web Development — Lesson 10 of 10 · Senior A successful deployment command does not prove a course application works. A release is complete when important user journeys work in the target environment and the team can recognize and recover from a bad change. This lesson turns a small course app into a practical release exercise with explicit acceptance and rollback criteria. Describe the change and its risk Suppose a release adds saved course shortlists. Separate the new browser interface, the server endpoint and any database change. Identify what happens when old browser code talks to the new server, and when the previous server version reads newly written data. Rolling back code is not the same as reversing a data migration. Write a short release record before deploying. Use real commit and build identifiers in your own project; the values below are placeholders for the exercise. Change: Add saved course shortlists Build: <immutable build identifier> Owner: <person ...

Hypertext vs Hypermedia: Differences and HTML Examples

-

Text component in multimedia and system design




Hypermedia:

  • Multimedia is the combination of text, graphic, and audio elements into a single collection or presentation
  • becomes interactive multimedia when you give the user some control over what information is viewed and when it is viewed.
  • Interactive multimedia becomes hypermedia when its designer provides a structure of linked elements through which a user can navigate and interact.
  • When a hypermedia project includes large amounts of text or symbolic content, this content can be indexed and its element then linked together to afford rapid electronic retrieval of the associated information.

 

Hypertext:

  • When text is stored in a computer instead of on printed pages the computer’s powerful processing capabilities can be applied to make the text more accessible and meaningful.
  • This text can be called as hypertext.

 

Hypermedia Structures:

  • Two Buzzwords used often in hypertext are:

§  link and node.

  • Links are connections between the conceptual elements, that is,
  • The nodes that might consists of text, graphics, sounds or related information in the knowledge base.

Searching for words:

  • Following are typical methods for a word searching in hypermedia systems:
    • Categories,
    • Word Relationships,
    • Adjacency,
    • Alternates,
    • Association,
    • Negation,
    • Truncation,
    • Intermediate words,
    • Frequency.

 

Practice: connect a text lesson to a video

Create an HTML page with two sections named Explanation and Demonstration. Add a link to the demonstration using a fragment such as <a href="#demo">Watch the demonstration</a>, and give that section id="demo". Test the link with the keyboard. The linked text is hypertext; connecting the text, image, and video makes the project hypermedia.

Multimedia combines forms of communication such as text, images, audio, animation, and video. An online lesson that explains a concept in writing, demonstrates it in a video, and gives the reader a quiz is a multimedia project. The goal is to help a person understand or complete a task, not simply to add more media. Multimedia, interactive multimedia, and hypermedia A recorded presentation is linear: viewers normally follow its sequence. Interactive multimedia lets a person control an action, such as replaying a demonstration or answering a question. Hypermedia connects information through links so the reader can choose a route. A course with linked lessons, diagrams, and video explanations can use all three approaches. Choose media for a learning goal Element Useful role Design check Text Instructions, labels, and searchable explanations Use clear headings and readable contrast Image Show parts of a device or a finished result Describe meaningful information in alternative text Audio ...

Internet vs World Wide Web: the key difference The Internet is the network infrastructure that connects devices and networks. The World Wide Web is a service that uses that infrastructure to deliver linked pages and media through browsers. Email and other network services can use the Internet without being web pages. HTML describes page content, HTTP carries web requests and responses, and URLs identify resources. The History of the Internet ARPANET was an early packet-switching research network funded by ARPA. Its first connected hosts appeared in 1969. Research on connecting different networks later helped develop the Internet. The Internet Society history, written by Internet pioneers , explains this development and distinguishes ARPANET from separate RAND research on military survivability. Key milestones in the history of the internet include: 1969 : ARPANET's first message sent. 1989 : Tim Berners-Lee proposes the World Wide Web. 1991 : The first website goes live, laying the...

VR replaces the user’s view with a virtual environment; AR adds digital elements to a view of the real environment. A virtual lab can let a learner inspect a model, while an AR lesson can place labels over a physical object. Choose between them according to the task, available devices and accessibility needs.   In the world of entertainment , virtual reality (VR) and augmented reality (AR) are changing the game. They're making our multimedia experiences more immersive and engaging. But what are these technologies, and how will they change how we enjoy multimedia? VR takes you into a fully made-up 3D world, letting you explore new places and experiences. AR adds digital stuff to the real world, mixing the virtual with the real. These technologies are set to change entertainment , from games and movies to live shows. As VR/AR get better, we can make multimedia experiences that are more interactive and fun.
