But it works well for public opinion, which is what politicians care about most, unfortunately

I see thanks, tbh my car is pretty crappy but if the uphill is too steep I will back up a little without handbrake and the guy behind me wont be happy :D

I'm curious, how do u do it? I mean you need a foot on gas and one on the clutch to start, how do you keep your car still without handbrake (other than just being quick after moving away from the brake)?

I agree with you, and yeah the convenience factor is in fact a huge problem and is highly exploited. The only thing I saw working are in fact laws to make the switch to another "service" more convenient (e.g. you have a messaging app? your protocol must be open source so that other clients should be possible by law, idk how feasible is this, but u get the idea).

 

A lot of posts like the one in the picture are mostly dominated by an image, that if tapped is just displayed as an overlay instead of opening the post. The areas where tapping cause the post to open are very small...

Is there a way of making it easier or a gesture I'm not aware of?

TLDR: no black hole was "detected", they were studying a cluster, and the presence of black holes might explain how the stars are positioned.

You actually summed it up pretty well! The few things I buy for myself are mostly "tools" to do/learn something that indeed fit your comment.

yeah, baking soda works but you have to be careful with the amount you put in them or they'll taste very bland after...

no I can confirm that it work without gapps on Lineage... probably something else...

Thanks for the interesting write-up!

Thanks, I'll have a look. It's an universal mains power supply with no voltage switch.

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?

Bought a new PC, and I was measuring its consumption out of curiosity. I noticed something weird (to me): when the PC is off (in fact, I completely disconnected the PSU and did the same test), there is quite some current running in the power cable to the PSU (0.15A).

Further measures showed a power factor of (almost) zero, and I can actually measure a capacity of 2uF across the PSU ac input.

I did the same thing on an older PC I have, and there is no current / capacity. So what would the reason of a capacitor across the mains on the input be in a PSU?

PS: the PSU is a Thermaltake Toughpower GF A3 1050W

Edit: I found some official measurements for this specific PSU: https://www.cybenetics.com/evaluations/psus/2249/ that have 40W standby apparent-power by design

Mi sono accorto che su alcune community i post non sono aggiornati (se visti da feddit). Ad esempio [email protected] l'ultimo post sembra essere di 9 mesi fa (quando invece ci sono post anche di oggi) E' normale?
