The Ephemeral Web and the Case for Proactive Archiving

The web is often treated as a durable record of institutional and social life, yet in practice it is fragile, revisable, and frequently ephemeral. Domains change, redesigns erase earlier material, institutions relocate, maintainers graduate, platforms impose silent limits, and periods of political instability can interrupt digital access entirely. This paper argues that archiving should not remain a niche activity practiced by a few specialists at the margins, but should become a proactive part of website maintenance. I motivate this claim through a case study centered on the Pakistan Embassy International School and College Tehran, whose domain, visual identity, leadership, and physical location all changed within a short period after my graduation. In response, I built and deployed a lightweight automated archival system using Python and GitHub Actions to submit pages and media from the site to the Internet Archive's Wayback Machine. The project shows both that archival preservation can be automated with modest infrastructure and that archival systems are themselves vulnerable to interruption, as illustrated by GitHub's automatic disabling of scheduled workflows after repository inactivity. Drawing on personal experience with internet shutdowns in Iran, open-source sustainability lessons from RPI's RCOS, and the operational history of the archiver, I argue that the ephemerality of the web is not an exception but a structural condition. If digital societies wish to preserve institutional memory and public history without leaving preservation to chance, proactive archiving should become a commonplace part of website maintenance.

The Inverse Function Fallacy: On Sign Determination and Forgotten Fundamentals

Although inverse functions are introduced early in algebra, many students remain unaware that an inverse expression may legitimately involve a negative root. Instead, they default to assuming a positive root, overlooking the role of domain restrictions in determining the correct solution. This paper identifies this misconception as the "inverse function fallacy" and introduces a systematic approach, the Inverse Function Point method, that establishes sign determination to a single domain-based reference point. In a study of 69 STEM students at Rensselaer Polytechnic Institute, only 19% solved a sign-determination problem correctly on their first attempt. Those students were not re-tested. Of the remaining 56 who answered incorrectly, I was able to re-test 40 after teaching the proposed method. In this subgroup, accuracy rose to 80%. These results highlight both the fragility of assumed mathematical knowledge and the potential of simple, intuitive procedures to reinforce conceptual understanding.
