Request for hashes [RESOLVED]
I'd like to ask somebody who has TLMC v.19 from 2018 (all 3: music, covers and supplementary) and TLMC temporary addon from 2023 to publish hashes of all their files. Just the output of "find /path/to/files/ -type f -print0 | xargs -0 sha256sum >> /tmp/hashes". If you're on Windows, I can find some powershell replacement.
>What happened?
I was listening to the music and suddenly heard a "PSSHH". Went to investigate and found that my array developed a case of silent corruption, probably courtesy of mdadm's new "--replace --with" functionality which does not verify the data it's getting from the failing drive matches the stripe checksum.
>Why don't you use the torrent to check?
Obviously, that was the first thing I did. However, file replacements and directory moves/renames over time mean I can't verify everything on full auto.
>Why don't you just download the torrent?
The impact on my copy of TLMC so far is 9 damaged files; downloading several terabytes to verify that's all there is seems like a useless waste of bandwidth.
Edited on 2025-08-11: now I only need v.19 music.
Edited on 2025-08-15: No more hashes needed for now.
Just in case you're wondering where I ended up: I'm running raid6check and it found a bunch of mismatches, all of which so far point to a single drive. The array is likely repairable without any data loss.
>Running?
~25 MB/s speed doesn't seem so bad until you realize that's 1 million seconds (11.6 days) for every 25 TB checked. Users complained to maintainers before, no one cared, business as usual.

AI and you.

For TLMC, other topics and latest posts please scroll down.
Recently discussion of artificial intelligence and consequences of its development has finally somewhat reached mainstream. I decided I needed to share my thoughts too.

TLMC "timeout" version, 2023.01.15
If you prefer your touhou albums somewhat disorganized, but later, rather than organized, but never, then this version is for you.
Single torrent : 1.55 TiB or 1 701 548 530 091 bytes.
Torrent file size is 18 106 928 bytes; contains 67 197 files.
Magnet link.
Added on 2023-04-25: Recent versions of uTorrent are broken (see user problems in comments) and will fail to open this torrent. Use other clients. I suggest qBittorrent.
This torrent contains only new content relative to TLMC v.19, so if you want a complete collection you need both.
