gif-from-tweet

There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.

Dependencies

• ffmpeg
  • macOS: brew install ffmpeg
  • Ubuntu/Debian: apt install ffmpeg

  return row['Exclusive Shelf'] !== 'to-read';

Here's an example of how to debug Mocha v4 if it hangs.

Ensure you're using a Node.js 8 or newer (or any version with async_hooks support).

If you run your test, you'll notice it hangs:

$ mocha test.js

If you were to give recommendations to your "little brother/sister" on things that they need to do to become a data scientist, what would those things be?

I think the "Data Science Venn Diagram" (http://drewconway.com/zia/2013/3/26/the-data-science-venn-diagram) is a great place to start. You need three things to be a good data scientist:

• Statistical knowledge
• Programming/hacking skills
• Domain expertise

Statistical knowledge

# Two very basic functions for searching just the input code of an IPython notebook
# Written because I often want to search notebooks for snippets but the giant output
# of embedded encoded images makes it difficult.

# Ipython's nbconvert can be used to extract just the input, but this requires 
# writing to a separate file and can be quite slow when used with large notebooks.
# Additionally, find/xargs can be used with igrep when the name of the notebook isn't known.

# icat could be used to convert an IPython notebook to a standard python file if 
# the notebook does not contain whole-cell magics.
