  • In the compsci building at uni, there is a museum of sorts in the hall to the labs. At the beginning of the storage section, there is a 20Mb storage device. It is the size of a washing machine, I have no idea how much it weighs, but it has to be in the 100’s of kg range.

    Sitting on top are much more modern devices, 5.25"/3.5"/2.5" drives; I haven’t been back for a decade to know if they kept going as tech improved.



  • I have multi-sensory aphantasia. No pictures/sounds/tastes/touch/smell. My inner voice is soundless but constant.

    I discovered aphantasia at 40; it is not a lack or detriment merely a difference. I talked with my Mum about it, she is has aphantasia and didn’t realise and she is 66.

    Aphantasia doesn’t hold you back or make life harder; especially since you can go decades without realising that you have it.

    You may have other stuff, ASD or ADHD etc…but aphantaisa isn’t in the same realm.















  • Retention of data should be determined by importance, one problem is we don’t know what will be important until it is needed.

    Who determines what is important enough to keep?
    If it is done by “AI” what are the rules?

    If we assume 2/3 of the 15k police staff are “front line” i.e. those wearing body cams; that is roughly 10k cams recording 24/7. Each camera records @1-2GB/hr; this comes to 24-48TB/day of data; even if we mark 80% of that data for immediate deletion because nothing is happening (done by AI). We are talking 5-10TB/day that will need to be reviewed to determine if it is important enough to keep long term.

    That is a lot of work; and a lot of resources to review the data. The storage quickly adds up; the benefits are huge, but the challenges of storage/security/privacy are equally enormous.

    We tried a lot of techniques…

    Rigid schedules, no schedules , big feeds, lots of little feeds…nothing seemed to work. For one kid, he wouldn’t sleep unless he was next to one of us; one of the others wanted to be in the same room but not the same bed…

    But once they hit ~3 it was like a switch flipped, and now they all sleep with no issues.
