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

Restore intentionally deleted commits in Git (remote)

Situation

1. You own a Git repository server and the developers do not have access to it (i.e. they can only read & write to the repo, but not gc it).
2. You had a developer that wrote a project for you.
3. He got angry for whatever reason and deleted all branches from the remote repo. He also push -fed the master branch leaving only one silly commit there.
4. He escaped from the country leaving you without any code at all (at least this is what he believe in).
5. You have never cloned the repo to other machine. There were only two copies of it: the developer's one and the server's one.

With visual testing we occasionally need to debug images in CI environments. We were previously using Imgur's v1 API:

https://github.com/twolfson/twolfson.com/blob/3.102.0/test/perceptual-tests/upload-screenshots.sh

but that's been shutdown and v2 and v3 seems like they need login for uploading images. We don't like that since these are rarely setup and we don't want to associate development content with personal content.

Thankfully Imgur supports uploading images via the browser without logging in. After trial/error, we got the following script for uploading a single image:
