  • Take the lesson, as it’s not hard, but it takes some practice making it seem effortless. With a lesson you’ll learn the basics, and the rest is just practice over a day or two.

    If you’re driving automatic correctly, your left foot should be available, and the only thing different with your feet is that your left foot now needs to handle the clutch. This means during (some of the) braking or other times when you want to disengage the drivetrain.

    After a little while you get a feel for listening to the RPM, and you begin to shift gear automatically based on the engine sound, or any planned changes in speed/torque.

    Oh, and it’s worth noting that most cars are somewhat different when it comes to clutching: Some have the car equivalent of a hair trigger, others are much more lenient. If you’ve gotten used to one car, trying out a different one might be useful.










  • Bingo.

    I used to work with internet on trains, and the system was relatively simple by today’s standards. Not so much back then, but:

    • One carriage had UMTS/LTE and CDMA modems and a router that load balanced between the uplinks. Usually in the restaurant carriage, because there would only be one per train. It also had a short range wireless link in each end for other carriages to connect.
    • Each carriage that could potentially be in the same train had wireless clients in each end for connecting “upstream” towards the router.
    • All carriages had a wifi radio

    On other words, many potential points of failure. And sometimes we’d get tickets such as this sent our way: “Internet doesn’t work”

    • No info about which carriage
    • No info about when
    • No info about where
    • No info about which train


  • I might as well go first: Basic troubleshooting and reasoning.

    I mean, we’re not talking debugging assembly language here. But at least you should be able to reply correctly to the question “is it dead or faulty?” when it comes to a computer. And when a your car has a weird noise, at least try to locate it for an obvious cause such as something rolling around under your seat.

    EDIT: And one important aspect of troubleshooting many people don’t get is how to narrow down the problem. Let’s say your wifi isn’t working - have you checked on any other device whether it’s working there? Someone else mentioned binary search which has a lot of overlap with this.
