BABEL_LIB

Named after the Library of Babel website. This started as an experiment in randomness but now hosts a bunch of experimental programs. I got help from chatGPT, Claude AI, and Bard to write some of them.

Setup

For initial setup, create a virtual environment & run it:

$ python -m venv venv
$ . venv/bin/activate

Then install requirements:

$ pip install -r requirements.txt

After the initial setup & requirements, you only have to run the second venv line to activate the virtual environment when running in the future.

Run

To run experiments, type python and the file name. For example, try this one:

$ cd ytdownload
$ python youtube_downloader.py

  2. Add to game 1 & see how many rolls it takes to roll the number again.
  3. Play game 2 a number of times.
• die_roll_probability.py - guess how many rolls it will take for game 2 (work in progress)
• die-roll-histogram - roll a die and generate a histogram of the values.
• squid_game.py - red light green light sim.

YouTube downloaders

• ytdownload/analyze_chat.py - Analyze a youtube live chat CSV output by youtube_downloader.py.

These use the yt_dlp YoutubeDL Python class or embedded CLI to download videos. You may want to install ffmpeg to handle some video conversion. Easiest way on macOS is through homebrew: brew install ffmpeg.

See Using yt-dlp cookies for how to download a video from X/Twitter
