This is very > hard for me to solve. I'm basically running off a raspberry pi right now. I don't have a lot of finances. I do have a number of external drives, but they tend to break faster than I can recover my files from them, resulting in a big queue of "to image/analyse" . I've been using git-annex, but I'm running into the issue that `git annex repair` seems to wipe my git history when I run into object corruption. What kinds of solutions exist already for large hash-addressed data integrity with history, that will work when the storage media are failing quickly?

oramfs looks pretty cool and is similar to things I'm working on. --- other yammer: Regarding filesystems, I'm struggling to find a way to preserve data across corrupt systems damaging it and harddrives that break frequently. This is very hard for me to solve. This list still makes no sense to me, no pgp keys, to me people say things that make little sense (spam filtering out of nowhere?). We need to get onto better channels. I wonder what people are using for discourse with more cryptographic integrity nowadays. I proposed to the lsl project (used for neuroscience research) that they encrypt and authenticate their biosignal streams. I wasn't sure what system to suggest and suggested hypercore because it offers some small proof of creation after the fact They were expecting TLS of course, which I worry around because it doesn't say anything about archival integrity after decryption. Hypercore wasn't really a good suggestion because it is written in nodejs and lsl is in c++ :-/ Seems go and rust are the future. I looked up go.sum : dependencies, although retrieved from github over the network (scary way to make an ecosystem) are hashed via sha256 in a way that can be upgraded (reliable, trustworthy). Inspiring. There are multiple facilities in the go dependency system, for pulling from offline mirrors instead of github, but they aren't that easy to find. Haven't checked if the commit id of dependencies is used in the hash, or the worktree checkout, or what. Haven't checked rust's cargo to see what their approach is. When picking a language, I want to make sure there are ways to quickly check where data corruption arises. I always use submodules and subtrees for my dependencies in older languages. It's cool that go's approach pressures people to mirror github to dev offline. That could accomplish a lot in the world, although is likely a little limited to things written in go.
