Converting HTML slides to a PDF with Firefox

Andy Balaam from Andy Balaam's Blog

I have not found an automated way to generate a nice PDF from some slides written in HTML – if you know of one please add a comment!

In the meantime, if you create slides using my HTML Slides template, then you can make a decent-ish-looking PDF like this:

  1. View your slides in Firefox and open the Print dialog (press Ctrl-p).
  2. Select Print to File and choose a filename to save to.
  3. Under Options deselect “Ignore Scaling…” and select “–blank–” for all the headers and footers. Ensure “Print Background Colours” and “Print Background Images” are selected.
  4. Under Page Setup set Scale to 70.0 and Orientation to Landscape.
  5. Select the dropdown next to Paper size and choose Manage Custom Sizes…
  6. Create a new custom size called “Screen 16:9” with Width 157.5 mm and Height 280.0 mm. Set all the Paper Margins to 5.0 mm. You can modify the name of the custom size by clicking on it in the list on the left.
    Click Close.
  7. Back in Page Setup, make sure your new custom size is selected next to Paper Size.
  8. Click Print.

If that does not work well for you, try experimenting with different Scale settings.

Migrating videos from YouTube to PeerTube inside a Docker container

Andy Balaam from Andy Balaam's Blog

I have quite a few videos hosted on YouTube that I would like to upload to my new PeerTube location, but I don’t want to install all the PeerTube dependencies on my machine, so I did it all inside a Docker image.

First I built and started a Docker container:

$ git clone https://github.com/chocobozzz/PeerTube /tmp/peertube
$ cd /tmp/peertube
$ docker build . -f ./support/docker/production/Dockerfile.stretch --tag peertube
$ docker run --tty --interactive peertube bash

Then I ran these commands inside it:

# yarn install --production=false
# node dist/server/tools/import-videos.js -u "https://peertube.mastodon.host" -U "andybalaam" -t "https://www.youtube.com/watch?v=TG0qRDrUPpA"

Of course, it would be better to write this up into its own Dockerfile to make this a one-liner.
