Problems

• $5 per month
• Users regularly join but then don’t attend
• Spam accounts

Benefits

• Email list
• Good discoverability
• Advertising
• Payment & Sponsoring support
• Attendance count

Static Website Hosting for Free

• It’s free
• No security or privacy concerns
• Easy to maintain
• (even allows for custom domains)

Continuous Deployment

• each commit triggers automatic rebuild and deployment
• mail notifications on build (or test) failures
• based largely on (but not limited to) Docker
• distributed runners

Quick Demo

Org-mode

• awesome source language
• allows HTML export
• assigns a few semantic css classes
• cumbersome to customize

Jekyll

• uses markdown with liquid templates
• configured via options in file or via args
• special support for blogging

Hakyll

• uses pandoc and pandoc templates
• configured via custom Haskell executable
• extremely flexible

Quick Demo

Pandoc

• universal document converter

• handles a shitton of input file types

  Markdown, Org, LaTeX, docx, odt, DokuWiki, epub, …

• own templating system

Templates and Partials

• Templates: Organize UI in html, write entries in org-mode
• Partials: split UI into smaller pieces

Context Matters

$title$, $date$, and $body$ change accordingly depending on its context.

Load and Apply Templates

Automatically filtering future and past talks is annoying

• Hakyll is a static site generator and the filtering is done only when generating.

  Can be worked around with scheduled rebuilds.

Stack and CI don’t play nicely

• Stack in Docker took waaay too long to build too much of the Haskell ecosystem.
• Can be worked around by CI caching.
• We switched to raw nix for CI (without Docker) as we both use NixOS anyway.
