  • Absolutely. If people accept it they’ll keep doing it.

    However, if they’re departing from a straightforward price tag where prices are consistent and pre-agreed, it sounds like we’re going back to the time of bartering. Anywhere that implements this, customers should be prepared to say no at the till. They might backtrack on this when customers with a huge trolley pull up at the checkout and then refuse to pay because they disagree with the amount.


  • If by discrete ICs you mean custom logic baked into silicon, yes that’s always been expensive. I was referring to off-the-shelf ICs that cost pennies, which used to be orders of magnitude cheaper even than PICs (in the days before Internet connected fridges).

    Before the term software engineer was commonplace, electronic engineers used design circuits around off-the-shelf components, like the venerable TI 555 timer or op-amps, and design a circuit around them. To do it they’d need the datasheets (https://www.ti.com/lit/ds/symlink/lm555.pdf). Hobbyists and aspiring young engineers would buy books like this: (https://www.computinghistory.org.uk/det/14021/IC-555-Projects/), which were like O’Reilly cookbooks for electronics circuits. The equipment to program a PIC used to be way beyond the reach of hobbyists, and wasn’t necessary for manufacturers producing simple control circuits. If you look at circuitboards from that time you’ll see some ICs with pins that aren’t connected to anything because those just weren’t needed for the circuit, much like you describe the empty sockets in modern boards.

    It absolutely was possible in the pre-Internet days to design a fully functional fridge, and more, without writing code of any kind, and it was cheap too.






  • I’ve often thought that we could polarise the headlight glass one way, and then windscreen glass the other. The glare off the road would still hit you but the lights themselves would be much darker, but still enough for you to see they’re there. The day-runners in the corners could still be unpolarised so you’d still see the vehicle. It’d be a bit more expensive and require collaboration between the manufacturers which are probably two large reasons why it would never happen.

    I’m sure solving this problem isn’t beyond the wit of humanity, but is beyond the expense threshold that the oligarchs will tolerate from their dividends.











  • In your initial response, you acknowledged that you understood what was meant by “sensors” in the context of the comment, but then the rest of your response was dismissive in tone, and implied that you believe their statement to be incorrect despite your previous acknowledgement. Your follow-up responses are doubling-down on this.

    As others have pointed out, arguing about the canonical definition of the word “sensor” is not adding anything to the discussion around the potential cause of the collision.
