Solar Protocol is a web platform hosted across a network of solar-powered servers set up in different locations around the world. A solar-powered server is a computer that is powered by a solar panel and a small battery. Each server can only offer intermittent connectivity that is dependent on available sunshine, the length of day and local weather conditions. When connected as a network, the servers coordinate to serve a website from whichever of them is enjoying the most sunshine at the time.

Solarpunks were prescient when they asked (in 2012):

What would computing look like if it had to get its power from purely local and renewable sources? What is the potential of low-and-no-power computing and sensor networks?

I would like to have a PDF viewer that lets me click a button (or press a key) to move backwards in the PDF file's git history. In effect, git checkout <commit> file.pdf but automatically moving back in the commit history on each keypress.

Combined with something like the overview mode of pdfpc, that could make for a very efficient way to glance through the history of a PDF file, such as a thesis or a beamer presentation.

So far I have not found any PDF viewer software with something akin to that.
Maybe I should just open the PDF in VSCodium and use the built-in git support? Would that provide something similar?

Lemmy communities (think subreddits) are given in this format: !communityName@instanceName.
Since Lemmy is on the Fediverse, you can follow Lemmy communities (think subreddits) from Mastodon, just replace the ! by @, and you should find the account name.
