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...

No. Windows ships already well compressed. There's no way it'll compress further by 50%.

I've been getting about that rate of compression consistently with Clonezilla on windows 10. I also didn't have any problems relocating it... it just start a driver update step and then reboots normally, but idk about how licensing work for this cases.

Invidious public instances have been completely blocked by this, it's no longer AB testing. IDK exactly what triggers it but, too many requests from the same ip is going to show this now... maybe OP vpn exits with an ip shared by too many...

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

I get what you mean, I think in a realistic scenario this only work to circumvent some laws. if you are tortured by someone who know about this and don't care about your life, then it's meaningless.

Does not "help protecting privacy", that is marketing. It's a system for ads that track you in a more privacy-friendly way then other alternatives.

Peoples are mostly angry at the fact that they just silently slipped this system in without asking for consent.

I meant that without these people who constantly work on it, Invidious would instantly die, we shouldn't take them for granted...Google is constantly making changes that breaks it.

[–] mattreb@feddit.it 2 points 6 months ago (3 children)

Btw they are not actually failing: just a few weeks ago Invidious was completely broken, but a guy posted a PR to fix that like the day after...

I kinda agree with you, being impossible to contact is probably unachievable in today society...Isn't it more important to avoid sharing more personal information, like your exact location history with Google? (or pls explain me the downvotes)
