  • I’m a dev but not very good at mobile.

    I can promise you that a lot of engineering work went into making the tiktok scrolling experience so smooth. Part of the trick is having a good enough algorithm that the user wants to watch the majority of served videos.

    Another huge part of it is having lightning fast content distribution and aggressive “prefetching” of the next videos in the feed.

    I don’t want to discourage you but I also don’t want you to be caught off guard by the difficulty. Do you want to make this bad enough to give it your nights and weekends for a year?


  • Rail is fundamentally superior to roads + cars at an engineering level.

    All at the same time:

    • Rail has a smaller footprint

    • Rail moves multiple times more people or cargo per hour

    • Rail has multiple times more fuel efficiency

    The fact that USA’s policy has been designed to favor cars only makes them more ‘practical’ than rail if you consider political constraints more binding than physics constraints.

    I’ll grant that trucks have tighter turning radii and maximum operating grade. If we truly only used them when those characteristics are needed THAT would be ‘practical’
