  • Left pedal looks more like a dead pedal to me.

    And as others have said, change in direction is still acceleration. That’s part of Newton’s (apocryphal?) apple story — he witnessed an apple falling, and wondered why the moon doesn’t also fall. His amazing insight is that it does fall (accelerate), it’s just that it falls in such a way that it orbits, rather than hits, the Earth (for timescales relevant to a human).









  • It is really powerful per watt, and has a built-in UPS. Any homelab type things you could do with that? macOS+homebrew will give you a nice *NIX feel, very familiar if you’re a Linux user.

    I’m a fan of having a remote homelab computer+disk for off-site storage. This would be a good candidate in that it wouldn’t use excessive power at a friend/family’s place, but may be overkill (I use a pi3 for that).











  • Same — rsync to a pi 3 with a (single) ZFS drive at family’s house. Retain some daily/weekly/monthly snapshots.

    I have a (free) VPS with static IPv4 which is how I connect everything.

    Both the VPS and the remote site have limited network speed (I think 50Mbps for VPS), so the initial sync was done sneakernet (well…“airplane net”). Nightly rsync is no problem bandwidth-wise, and is mostly just any new videos I’ve uploaded to my local Immich instance.
