Update last edition talks with new gifs or remove section

[Readpato]

We need to add more cards and youtube links. Pretty easy issue if someone wants to pick up

New talks need to be added to the file constants/index.ts

It's a series of simple objects. What matters the most is the name and id

  {
    id: "omar1", // must be unique
    description:
      "Omar Diop - Perfect Pitch: Unveiling the Mathematical Symphony Behind a Guitar Tuner",
    link: "https://www.youtube.com/watch?v=W9HBHDogaFU",
    picture: "",
    author: "omar", // must be unique and match gif and css
  },

Once we have the array of talks2024 filled with data, we can move to the css file.

Each new talk card needs a :hover rule, like the following:

.talk_card_inner.omar:hover {
  background-image: url("/gifs_2024/omar.gif");
}

This implies that we also need a gif which can be generated by recording parts of the youtube videos and then converting those videos to gif.

Here is a simple utility to do just that, if you have ffmpeg installed.

alias convert2gif = function _xxx(){ffmpeg -i "$1" -vf "fps=10,scale=320:-1:flags=lanczos" -c:v gif -f gif "${1%.*}.gif"};_xxx

You can add this function to your .zshrc or .bashrc directly. To install ffmpeg you can use homebrew:

brew install ffmpeg

An example usage:

# You recorded the video and it's sitting on your Desktop

mv recording.mov name_of_speaker
convert2gif name_of_speaker

# Now you should have a name_of_speaker.gif which you can move to the talks_2024 images folder in public
