How and why I attempt to use Links as main browser

Serve Videos Instead of GIFs
The Graphics Interchange Format ( GIF ) is over 30 years old but is a pervasive part of internet culture. We use GIFs to serve short, silent, and looping videos, which frequently become memes . Entire services exist to create and share them, and many smartphone keyboards have built-in GIF support.

Fragile narrow laggy asynchronous mismatched pipes kill productivity
Something I’ve been thinking about recently is how when I’ve worked on any kind of distributed system, including systems as simple as a web app with frontend and backend code, probably upwards of 80% of my time is spent on things I wouldn’t need to do if it weren’t distributed.
