Alan Dipert web history archive

This directory preserves selected Internet Archive captures from two sites owned and written by Alan Dipert:

• neologic.net, including the personal site at /ad
• alan.dipert.org, a Tumblr-backed technical blog

The material was recovered on 2026-08-09. The two compressed WARC files are the preservation copies; their companion CDX files index the responses inside them.

What was recovered

alan-dipert-org.warc.gz contains 97 selected Wayback replay responses:

• 79 distinct blog posts, with one late capture selected for each Tumblr post ID
• 15 RSS snapshots spanning October 2008 through May 2013
• three homepage snapshots from 2006, 2008, and 2013

The posts include the structural-editing series, “Polyglot Folding,” “The S-expression Editor,” “Discover Lisp in Your Web Browser with Javascript,” “Why PHP REALLY won,” Scala and Clojure examples, shell snippets, early Go notes, and other short technical and historical pieces.

editorial-index.tsv gives every one of the 79 recovered posts an explicit disposition. Eight substantial technical pieces are selected for the public RecoveredTechnicalWriting collection. The rest remain repository-only; entries with obsolete security advice or dated tone are marked so future editors do not publish them accidentally.

neologic-net.warc.gz contains 126 selected targets and the responses reached through their redirects:

• 25 versions of the company homepage from 2001 through 2004
• all 100 distinct indexed captures under /ad
• the sole indexed /ps/ response

The /ad material spans 2002–2007 and includes personal homepages, source code, Java applets, shell scripts, the edge-detection and classwork pages, OpenWrt notes and images, a Life applet, and early weblog fragments. Some captures expose server-generated output such as an old phpinfo() page; that output is preserved as historical data, not as documentation of the intended site.

The recovered pages also confirm both old AOL identities. Five captures of /ad/aboutme.php, from February through December 2003, identify “Completely Crazy” as Alan's AIM screen name. The Neologic 404 page reached by the July 2001 /ps/ redirect lists neutronbum@aol.com as the webmaster. No AOL Members or Hometown page URL appears in the selected captures.

The Wayback index has no surviving ProblemScan download. It records /ps/ as a redirect in July 2001 and problemscan1.zip as a 404 in October 2005. The original program was recovered independently and is preserved in ../problemscan/.

Files and provenance

• alan-dipert-org.warc.gz and neologic-net.warc.gz contain the HTTP exchanges downloaded through the Internet Archive's id_ replay mode, which omits the Wayback toolbar.
• The adjacent .cdx files were produced while writing the WARCs and provide offsets, response codes, media types, and payload digests.
• source-indexes/ contains the Internet Archive CDX API results used for the search. The full indexes retain alternate captures that were not selected for the WARCs.
• selections/ records every Wayback replay URL requested during recovery.
• SHA256SUMS verifies every preserved file except itself and this readme.

These are WARCs of Wayback replay responses fetched in 2026, not copies of the Internet Archive's underlying crawl WARCs. They preserve what the archive served at recovery time, including any server-side replay behavior.

Verification

From this directory:

sha256sum -c SHA256SUMS
gzip -t alan-dipert-org.warc.gz neologic-net.warc.gz

The WARC files can be inspected with standard WARC readers or replayed with a tool such as pywb. Treat recovered executables, scripts, and server output as untrusted historical material.
