  • A dedicated server is needed because something needs to keep a catalog of the smart devices available on your network and ideally be accessible to many people in one household. You could make a system that went phone -> device but you would need to set up each device on each phone you wanted to use, which isn’t a great user experience. You could also run into issues where devices would need to handle multiple conflicting commands from different users coming in at once. Since smart devices are usually trying to use as little power as possible, that extra complexity would hurt you in that department. The third reason is that having a separate server enables automated workflows that would depend on an always online server that orchestrates multiple devices. For example, let’s say you have some automatic insulating blinds, a smart thermostat. You want to raise and lower the blinds to maximize your energy efficiency. Since you have the dedicated server, that server can check the temperature set point of your thermostat, current weather, and sunrise\sunset times. If it’s sunny out, and your set point is higher than the outdoor temperature, the server can raise the blinds to let warm sunlight in, and vice versa. If only your phone could control the devices a workflow like this couldn’t work when you were out of the house.










  • In this case it’s likely partly a signal to noise problem that can’t be mitigated easily. Both children and dark skinned people produce less signal to a camera because they reflect less light. children because they’re smaller, and dark skinned people because their skin tones are darker. This will cause issues in the stereo vision algorithms that are finding objects and getting distance to them. Lidar would solve the issue, but companies don’t want to use it because lidars with a fast enough update rate and high enough resolution for safe highway driving are prohibitively expensive for a passenger vehicle (60k+ for just the sensor)






  • Streaming and hosting white noise on their servers costs them money, most people who are using these podcasts probably just do it while they’re asleep and happen to have a spotify subscription. These people aren’t going to cancel a subscription because they need another app for white noise.

    Spotify could add a generator for white noise soundscapes to their app, but there are countless applications that do this already for free, including open source options. If they aren’t giving money to people uploading soundscapes, they can take more money from monthly subscriptions themselves and give more to artists, increasing their profits and making their platform more desirable than their competitors, which has been an issue for them in the past with criticism from major artists and indies alike.

    Overall these noise streams exist to game the system by getting people to play for a long time on content that’s probably just made by hitting the play button on a generator app written by someone other than the uploader, and it’s likely the only reason it happens is people don’t want to download an additional free app for that task
