    1. DNS resolver, like pi-hole, unbound with adguard, diversion, etc.
    2. RMS server: a lot of Remote Desktop software has the option to install a listener on a low power device elsewhere on the network that can use wake-on-lan to access computers within the network without keeping everything on 24-7.
    3. Log aggregator: would be useful for anyone who troubleshoots stuff regularly, but historical info of any kind can come in handy.
      Simplest form might be a scribe server. Network gear often has an option to send logs to a particular URL, so if you added the scribe server IP/port to the field you’d have historical network logs.
    4. Additional loggers: could also be run on-device, such as a wifi connectivity checker, smart home or energy monitoring state data, decibel meter with USB microphone
    5. RADIUS server for managing enterprise WPA keys
    6. Mobile home: due to the size and power draw, when paired with a hotspot and battery the potato could be useful as a mobile service repeater, a VPN client that deploys your home services on the go (e.g. in a vehicle, hotel room, family/friends’ houses, etc) to arbitrary client devices. If you use the same SSID/PW and encryption type, personal devices would use it automatically during travel.
    7. Home theater box like kodi or jellyfin client

    At the level of individual apps, the list explodes. Many progressive web apps can be hosted essentially for free on the potato, so you could shunt your always-on services to this machine to allow low power states on a beefier machine. For example:

    1. Network management or security software like Fing
    2. Low throughput NAS or incremental backup management server like rdiff, TimeMachine, etc
    3. inventory management like partkeeper, storaji, etc
    4. Smart home bridges like homeassistant or homebridge
    5. Bookmark aggregator or landing page like heimdall, raindrop, pinalist, etc
    6. Retro game emulators or ROM libraries like retropie
    7. Photo libraries like photoprism
    8. Book libraries like calibre-web

    Edit: list subitem formatting messed up
    Edit: add common micro services, mobile deployment
    Edit: add home theater suggestion
    Edit: add always-on and PWA examples









  • Maybe yeah. Also got the sense from the strong opinions that this is a preexisting debate, presumably in the context of continuous workloads or cached arrays with minimal spindown intervals. In that context it’s true that rotational disks still often win in energy efficiency and robustness (assuming we’re comparing them to consumer SSDs and not the latest enterprise u.2 stuff that’s rated for continuous work).


  • Not sure what everyone is arguing about here. Clearly SSD is better for intermittent r/w, whereas HDD can be more efficient at continuous r/w (especially in terms of watts/TB)

    Just looking at specs should be enough to see that. SSDs can idle in ready state at close to 0 draw (~0.05w) whereas HDD requires continued rotation to remain ready. So consider an extreme case of writing for 1 minute then maintaining ready state for the rest of the day. For that the SSD will be far more efficient, obviously.






  • In the end people/companies will pick the proprietary / closed option just because “it’s easier to use” or some other specific thing that will be good on the short term and very bad on the long term.

    I agree with most of the above, just wanted to relay an explanation given to me years ago by my then eng director in an argument about this. He said the reasons we tend to use proprietary / closed platforms and deps in business settings is not necessarily because the software was better or easier to work with. Clearly it often isn’t.

    It’s because of (1) built-in factoring and infrastructure, (2) built-in domain expertise that would otherwise require hiring or training, and (3) contractual guarantees that can be invoked when things go wrong. All of which attenuate risk and make development timelines and outcomes more predictable.

    His line was “OSS is free like a puppy is free.” That is, most businesses aren’t old enough to handle the responsibility, and that’s why we still sometimes use shitty proprietary software.
