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

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

• The link below in the summary jumps at the answer on this page.
• The link on the question itself points back at the original post.

Joining CSV Tables in Haskell

This article describes a technique for joining (in an SQL-style) lists of haskell data structures.

Maybe not the fastest, maybe not the smartest, but it works.
