    How were you measuring the current in the power cable? Is this with a Kill-o-watt device or perhaps with a clamp meter and a line splitter?

    For the current both with a line-splitter+clamp and checked with an in-line meter. For the power factor, since I don’t have any actual instrument to measure It, and I just needed a ball-park figure to discern actual consumption from a capacitor, I used this diy method: https://www.giangrandi.org/electronics/cosphi/cosphi.shtml , which measured 0.04 ( with great approximation ).

    As for why there is a capacitor across the mains input […]

    I have the basic on how a switching power supply work, but I was asking because it seemed weird to me that commercial appliances didn’t take any stand-by meaures to avoid “keeping the wires warm”… is this the norm?





  • The point is just differentiating your behavior between what you call a “bad” or a “good” junior.

    And from experience the difference is whether they want to learn (regardless of their skill!!) or not (i.e are they passionate or it’s just a job?).

    Passionate seniors get frustrated when they try to teach bad juniors, but there is no point on doing that, the problem was just that the senior was not involved in the hiring process…






  • I’m currently on a TLK, and mostly because I want to learn to stop moving my hands away from the home row. It’s not even only about arrows, but also home/end page up/down etc. and combinations with them which I use a lot and it just get slow and weird since I have to reposition my hands every time… mine is currently quite limited in what I can program it to do unfortunately.
