Love love love media.ccc.de by Chaos Computer Club. And I love that all of the files are available via their CDN.

A screenshot of a web directory listing titled "Index of /congress/2025/h264-hd/". The page displays a list of video files and documents from the 39C3 conference, including multilingual recordings of ceremonies and talks on topics like AI, Rust programming, and government access.

Browsing to the corner of the CDN with 39c3’s videos I decided I wanted to pull down only the English versions.

This is the shell one-liner I wrote to parse the HTML, filter it via awk and looping through to download just the files I was after:

curl -sL "https://cdn.media.ccc.de/congress/2025/h264-hd/" | \
  grep -oE 'href="[^"]*\.mp4"' | \
  sed 's/href="//; s/"$//' | \
  awk -F'-' '{for(i=1;i<=NF;i++) if($i=="eng" && $(i+1) ~ /^[a-z]{3,}$/ || $(i-1) ~ /^[a-z]{3,}$/){next} else if($i=="eng")print}' | \
  while IFS= read -r file; do 
    wget "https://cdn.media.ccc.de/congress/2025/h264-hd/$file"
  done

If that’s not so much your thing, their frontend is nicely accessible as well. https://media.ccc.de/c/39c3

A screenshot of the media.ccc.de website displaying the "39C3: Power Cycles" video playlist from the 2025 Chaos Communication Congress. The page lists several talks with thumbnails and titles, including a presentation by Cory Doctorow on an "ensheittification-resistant internet" and a talk titled "Hacking washing machines."
