  • Gotcha. I had a feeling something around how Mastodon doesn’t support ActivityPub Groups (yet?) would be where things are going on. Congrats on piefed, by the way. I’ll start studying the codebase now as I’m keen to understand how server-to-server communication works more deeply than I do now. Sending Announce(?) and fetching stuff from other servers…

    When I look at the ActivityPub Note object (via curl -H 'Accept: application/activity+json https://hachyderm.io/@otl/111887721960075860) I see:

    {

                "items": []
            }
        }
    }
    

    So I’m assuming an Announce was posted to the shared inboxes at lemmy.ml, lemmy.world and ttrpg.network… hmm… I better start reading!









  • We can never know exactly. For me I always think about the (incidental) complexity of these huge apps like Instagram.

    Somebody mentioned the phone overheating when watching Reels - those short videos. Here’s a made-up example (but I’ve written some software for video streaming services)…

    Those videos are pretty short, and some people skip the clip even after less than 1 second. Instagram want that next video to be playing instantly (gotta get that dopamine hit ASAP!). A strategy you could take is have the app load the next, say, 5 possible videos in the background before you’ve even seen them. When the user swipes, that video is already playing. To make this even faster we could execute some recommendation decisions on-device rather than on some servers (over a relatively much slower 4G connection).

    With all this complexity comes greater chance of some unexpected behaviour. Instead of loading 5 videos, maybe we accidentally load 100 and never clean up the old ones. Maybe after an OS update we need to change the way we mark a task as low priority.




  • Instead they’re bitching about investments in science.

    Agreed. To be fair, I can also see where the frustration comes from. We see “deals with the devil” being made, but the (disappointing?) reality is tech progress often looks like that. Flashy stories with pie-in-the-sky ideas get headlines and funding. Meanwhile the boring, difficult work continues on in the background. From the outside it seems non-sensical and inefficient: why couldn’t they just invest money directly into GPS research without all the military stuff? But, fortunately, some amazing stuff does come out of it too.




  • I see where you’re coming from. Battery electric vehicles I think are a good example of trickle-down. It seems the R&D for electric cars affordable to wealthy people leads to new infra and tech for a changing power grid, buses, trains and bicycles.

    But two examples you raised:

    • corrective lenses
    • refrigeration

    have clear quality-of-life and health benefits. Supersonic passenger flights feel more like a luxury and convenience compared to food preservation.

    Hopefully in the development of reduced flight times between other sides of the world we perform research with impact beyond flight. Things like improved materials, fuel, aerodynamics that could be used for trains and trucks. I’m not an engineer but I hope it works like that!
