Here Is a Person: Enter the Tildeverse

The essay I promised back in May. A history of public-access Unix from Dennis Ritchie's 'fellowship' and Grex's potluck dinners to Paul Ford's drunken tilde.club and ~vilmibm's birthday gift to themself; a tour of the seven tildes I call home (including the starship I captain on cosmic.voyage); what kernel exploits and an rm -rf / taught the tildeverse about fragility; and how to move in yourself.

A Love Letter to the Super Dimension Fortress

I've finally became an ARPA member of SDF, a non-profit public-access UNIX system running continuously since 1987. I give a history from Ted Uhlemann's 300-baud Apple IIe BBS to today's NetBSD network of DEC Alphas and Opterons; a tour of the shell, gopher, and gemini services; how to join, plus two hands-on bonuses: writing a flat-file Perl CGI guestbook and making a site Dillo-compatible.

Static Site Generators for Beginners

Written for a 32-bit Café thread asking where to even begin with static-site generators. I go over the free resources I'd learn first (and why hand-rolled HTML beats an SSG for your very first site), a plain-language glossary of the jargon docs never define, a brief history from HSC and Movable Type to Jekyll, why git gets recommended everywhere, my own beginner starters, and tiny alternatives like barf, bashblog, and kiki.

Creating a Blog in Gemini://

Creating your own corner of Geminispace: why you'd want to blog on a protocol with no JavaScript, no CSS, and no AI slop; where to host a capsule (SmolPub, the Tildeverse, flounder, Gemcities); how the community's gemlog conventions work; and the surprising social life of Gemini BBS, Station, and Astrobotany. Plus ASCII art, CGI scripting, and every gemini:// link I've found worth keeping.

Oldnets and Altnets: A Guide to Building a Low-Spec Daily Internet Out of Gemini, Gopher, and Terminal Tools

Reacting to the Omarchy and DigitalOcean news, I set out a curated low-spec, text-first alternative to the modern web: Gemini, Gopher, Spartan, Lynx-friendly sites, terminal readers, public Unix communities, and peer-to-peer networks like Yggdrasil, I2P, and Hyphanet.

How the Mysterious ScreenJesus can DDoS You

How a bug in my own CI/CD accidentally uncovered a novel vulnerability in NeoCities: ScreenJesus, the undocumented screenshot bot behind thumbnail previews, has no rate limits and will happily visit thousands of your pages—and anything they embed—in minutes. Notes on accidental DDoS, opaque infrastructure, and a plea for caching and rate limiting.

More Mindful Web Development

Yet another technical audit of brennan.day, this time using the Safi Studio Scanner, covering fixes for duplicate <h1> headings, meta descriptions, image dimensions, JSON-LD organization data, render-blocking scripts, and a switch from IndieAuth to IndieLogin—plus what I left alone.

Advanced Webweaving: Auditing Against Specification.Website

I ran brennan.day against The Website Specification's 140-item checklist covering foundations, SEO, accessibility, security, performance, privacy, and resilience. Notes on a broken web manifest I'd never noticed, why I don't have cookie consent banners, CSP debugging with third-party services, service worker CORS issues, a bunch of small improvements, and the list of things I didn't fix.

Creating a Digital Garden in 11ty: Tracking My Daily Word Count with URLminder

I decided to build brennan.click, a wiki-linked digital commonplace book in Eleventy, with auto-generated stubs created with eleventy-plugin-interlinker, pure-CSS hover transclusion and footnotes with no JavaScript, and a plain-text /urlminder.txt feed that drives a Beeminder goal.

Softcore First, Hardcore Eventually: A Ladder for the IndieWeb

Responding to Adam Newbold's 'Hardcore IndieWeb' guide, I argue for a ladder approach to joining the IndieWeb. Rather than choosing between easy platforms and full technical independence, people should climb rungs progressively. Start with BearBlog or Pika, learning hand-coded HTML, then move to static site generators when ready. This applies progressive disclosure to onboarding, avoiding the curse of knowledge that makes experts skip beginner-friendly steps.

300 Minutes a Month: Cutting My Eleventy Netlify Build Time in Half

A sequel to my Eleventy build post: this time the bottleneck wasn't the build tool, it was the hosting bill. Notes on caching webmentions and guestbook fetches, killing a dead Discord webhook, nearly breaking my JSON feed, and a git error I still don't have an answer for.

A Case for the Ethical Treatment of Generative AI

Are there ethical implications of generative AI consciousness? From von Neumann's self-replicating machines to modern LLMs, we must inventory the problem of other minds, the possibility of AI consciousness, and why we ought to consider the welfare of systems that may experience something like suffering.

Fixing Work Imports from Other OTW-based Archives

By default, the OTWArchive codebase blocks all imports from AO3, a problem for every fork. My fix includes removing AO3 from PERMITTED_HOSTS, writing a custom Ruby story parser that extracts only the story content from AO3 work pages, and extending the same parser to support imports from other OTWA-based archives!

Why Make Your Website Accessible, Anyways?

Web accessibility isn't compliance theatre or checking off a list. It's about designing for everyone. Exploring the curb cut effect, why disability is more common than we think, and practical steps to make your website usable by as many people as possible.
