  • I would guess there’s an upward slope of young contributors that reduce significantly at post-grad and early career ages (e.g. early-mid-twenties) followed by another upward gradient on a 5-10 year delay that peaks in the late 30s then falls somewhat linearly up to 60s.

    The median age of the younger/learning cohort might be 19 and falling. The median age of the established developer cohort might be mid-40s and climbing.


  • Yes, insofar as many reflexive actions, enervation and fiber recruitment thresholds respond to training, such that they “remember“ actions you have performed many times before. There are many clusters of nerves throughout the body called ganglia that are responsible for low-latency control of various functions that would entail too much delay when controlled entirely by the brain.

    Generally, the minimum input-process-activation turnaround time of the brain is about 4 hz (240-250 ms) which is too slow for many applications of motor function. But the “co-processing” allowed by the extended nervous system enables the body to, with practice, execute far more rapid and complex action sequences in response to local stimuli. Some actions can be triggered and completed before a signal even makes it to the brain.













  • It looks like there’s still moisture inside those switches. I would let it fully dry out before troubleshooting further.

    You can hasten this with isopropyl alcohol or a hair dryer. Opening the switch would be best but keeping the switch depressed will also allow more air in.

    Once internal moisture has evaporated, you might find that after a certain number of presses, the corrosion on the contacts wears enough that the keys become reliable again.


    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
