  • I found a cool way of ad-blocking back when I watched TV. Probably does not work anymore, and relies on Teletext page 888 (closed captions, the number varies by country) not being updated during ads.

    1. Mute
    2. Switch to another channel and back to clear Teletext cache
    3. Turn on fullscreen Teletext, any page (I like the 89x test patterns)
    4. Type “888” as the page you want to go to
    5. The TV will now wait for 888 to be broadcast, which only happens after ads and trailers
    6. The program is now running with captions. Disable Teletext and unmute if you want sound instead.





  • Amateurs.

    The 1963 Černý Důl – Kunčice nad Labem aerial ropeway is over 8 km (5 mi) long, over 30 m high in places and carries 135 tons of limestone every hour from a quarry to the nearest train station. Its 120kW 3-phase synchronous motor requires power for a few minutes at the start and end of each day when most of the 800kg-capacity trolleys are empty, and spends most of the shift generating mains electricity and acting as a speed governor. Unlike the EV, it is fully autonomous most of the way, only 5 people are required to operate it. (Loading, unloading and timed dispatching is automatic, arriving/leaving carts just need to be checked; a safety latch has to be manually dis/engaged on trolleys passing the check.) The quarry will continue operation as long as it pays off, then the ropeway will be scrapped (projected 2033). A dude illegally rode the way up on it somewhat recently. He could have fallen to his death if he pulled the latch.
