Internet Archive Incorrectly Wrapping Valid HTML

This example demonstrates how the Internet Archive’s Wayback Machine inserts its banner and analytics scripts into an archived page, wrapping a Polymer web component’s `<dom-module>` and its script in unexpected ways. The archived HTML shows the original valid structure disrupted by added script tags and a `textarea` element containing code, breaking the component’s expected parsing. It uses Polymer’s element registration and observers, plus XMLHttpRequest for fetching data, highlighting the mismatch between archived and original HTML.

Gist 2d272134b57b02eb8cdd0c5904249591

This example tests the archival fidelity of a web page by loading a series of images and scripts that mimic dynamic behavior, including DOM manipulation, AJAX requests, and delayed updates. It uses JavaScript’s `XMLHttpRequest` to fetch remote images and replaces them via base64 data URLs, while `setTimeout` and scroll events trigger asynchronous content changes. The page is rendered within an iframe by the pywb web archiving tool, with a banner and rewrite layer applied. The visualization demonstrates how archived sites handle live interactions and resource loading over time.

Still Drinking Gin And Juice

This example plays a trick on the Wayback Machine by loading a hidden iframe that captures the archived page’s React and ReactDOM libraries, then re-mounting a new React component inside that iframe. The visualization itself is not yet defined in the provided snippet, but the code sets up a full-screen canvas-driven animation framework using React and the browser’s native canvas and animation APIs. Images of frogs and a banner are fetched from the Internet Archive’s geocities.com captures, hinting at a playful, retro-themed visual collage. The page also manipulates browser history to disguise its origin and hides the archive’s toolbar.

2017-07-25: Swimming In A Ocean Of JavaScript. Using Nodejs, Electron And Chrome To Preserve The Web

This example demonstrates a Node.js toolkit for web archiving, showing how to parse, stream, and generate WARC and CDXJ files to preserve web content. It uses the `cdxj` library to read CDXJ indexes asynchronously, the `node-warc` parser with event listeners for streaming WARC records, and a configuration object for the `squid` crawler that controls Chrome via its WebSocket API. The code highlights handling HTTP/2 limitations in archives and supports features like page-same-domain crawling and auto-scrolling.

Web Archive Bookmarklet Code

A one-line JavaScript bookmarklet opens the current page in the Internet Archive’s Wayback Machine. The code triggers `window.open` on the URL formed by concatenating `'https://web.archive.org/web/'` with the live document’s `location.href`. This example demonstrates URL string construction and the Web’s `window.open` API for navigation, with no charting or graphics libraries involved. The plain text snippet contains no data visualization logic, showing instead a minimal utility for historical page capture.

CS 891 Web Archiving Seminar

This visualization demonstrates the process of web archiving by showing the WARC file records produced when using `wget` to archive two websites: `http://example.com` and the React Router documentation. The code uses `wget` with extensive arguments including `--mirror`, `--warc-cdx`, and `--page-requisites` to capture complete page snapshots. The example displays the resulting WARC file structure, containing request, response, metadata, and resource records, along with a shell script that orchestrates the archiving workflow and manages the Wayback Machine collections.

pywb proxy mods

This visualization shows the internal logic of the pywb web archiving proxy, displaying how HTML, CSS, and JavaScript content is rewritten during replay. The animation illustrates the code paths for rewriting HTML tags and attributes via the `HTMLRewriterMixin`, and content sanitization through `RewriteContent` using regex patterns for meta refresh and charset detection. The wombat.js script implements client-side URL rewriting with a JavaScript state machine that handles absolute, relative, and proxy-mode URL transformations. The gist demonstrates the interaction between these Python and JavaScript modules in the pywb rewriting pipeline, emphasizing the regex-based parsing and URL manipulation strategies.

Untitled

This example demonstrates a raw HTML page that renders the text “Hello HTML” at a massive 13em font size, while also logging “Hello JavaScript!” to the browser’s developer console. It serves as a minimal test of basic webpage structure and inline scripting. The code uses no external libraries, relying solely on plain HTML, CSS, and a small JavaScript snippet. The visible outcome is purely textual, with the script’s output appearing only in the console, not on the page itself.

This visualization tracks the client-side rewriting of a single webpage archived in the Wayback Machine, logging every URL modification made by JavaScript functions. It tallies 357 total rewrites and 13 HTTP 404 errors, breaking down calls by API (such as `Element.setAttribute`, `Node.appendChild`, `Element.innerHTML`, and `document.write`) and by element and attribute type, with counts for each combination. Raw server logs and rewrite logs are appended, showing specific requests and error responses. The data is rendered as plain text tables and log excerpts, providing a quantitative audit of archive-injected behavior.
