i guess that fb does store keys after all; they do respond to police requests

i also found this: https://www.reddit.com/r/privacy/comments/v7tsou/is_whatsapp_lying_about_its_endtoend_encryption/

Encryption in WhatApp is actually a fake, because the encryption keys are generated and stored on Facebook’s servers, accordingly, they can read any of your messages as plain text, and the intelligence services obviously have access to them.

Also a few months ago there was a leaked slide from an FBI training course or something where they compared different messengers in terms of how well they cooperate with the police, guess who came first ?

WhatsApp provides data to the police in near real time (about 15 minutes from the time of the request)

The message from WhatApp at the beginning of the chat - that your data is not available to third parties is the height of hypocrisy.

whatsapp is not meaningfully e2ee

sounds like it’s not supposed to be a general use tool, but instead for counterintelligence only:

The Ministry of the Interior anticipates submitting around 30 requests per year for the surveillance of unencrypted messages and between 5 to 15 requests for encrypted communications. If there are 30 instances of encrypted message monitoring within a single calendar year, the Interior Minister is obligated to inform a permanent subcommittee of the National Council, which is the directly elected chamber of the Austrian Parliament.

Each surveillance method will require case-by-case approval from the Federal Administrative Court. The process involves a legal protection officer from the Ministry of the Interior, who will have three business days to respond to any request. Following that, a panel of three judges from the Federal Administrative Court will review the case. In urgent situations, an individual judge may grant approval, supported by a 24-hour judicial service system.

broad use would expose its existence and make any 0days useless in short order

i don’t know if you know, but tobacco trafficking, at least before war, was a massive activity with counterfeit cigs showing up as far west as UK, and there were multiple groups involved, evidently some less cautious than others. also this article is five years old

in many flats even recently built you don’t get three-phase power, just single phase, but building divides single three-phase supply into three groups of single phase circuits like you say (do you really need 20kW in residential flat? one that doesn’t use EV charger, built in 90s-10s?) i guess it depends on country also. separate houses tend to get three phase connection where i live

floating neutral will also be a problem in american-type two-phase installation, might be even worse (more frequent) on account of large number of lightly maintained transformers used (why on gods green earth there’s few-kV medium voltage line going down every street, americans make it make sense)

Today many of switching mode power supplies accept anywhere between 100-250V

bases of pins are insulated, like in type C/E/F

you don’t have to have three phase circuit to be affected by floating neutral in three-phase substation upstream. in some places in us there are 208v interphase three-phase circuits, which give 120v phase to neutral, which is distributed as a pair of wires as single-phase circuit. this is also normal way to deliver single-phase power in europe, as it’s most efficient use of conductor. (from 400v three-phase circuits) in case more power is needed than single-phase circuit can deliver, three-phase circuit is installed

if there’s switch on device, it’s 2p1t meaning both phase and neutral are switched. if it’s permanent, non-pluggable circuit, like lightning, it’s okay if only phase is switched (neutral is connected permanently)

it’s a bad practice to design appliance in such a way to assume that neutral will have low voltage, because in case of neutral failure in three-phase circuit you can get full voltage there, and there can be a couple of volts difference (sometimes more) between neutral and ground even in normal circumstances

it’s better to cut off both live and neutral at the same time anyway, especially if there’s no standard which is which. also, as device designer you don’t know if it’ll be used on a circuit that has neutral and phase where you think it’ll go or not. (ie british appliance used on unpolarized circuit, like type F. adapters exist)

Type E/F carries 16A/230V, and nowadays there are shutters included which only allow two pins to be inserted at once, not one but not the other. There’s no standard as of which pin should be L1 and neutral anyway, nor it should matter, and fuses in british plugs are to accommodate ring circuits, which were introduced as a result of copper shortages (ie decades of tech debt)

Or you could just use thicker wires like everyone else, or drop the use of ring mains, which is the actual reason why fuses in plugs were introduced. The reason why this was done was post-WW2 copper shortage. In other countries you’ll see more likely star type circuit

I think that type A plug would be greatly improved in terms of safety and mechanically if it was put in a grounded metal shroud, in style of DIN connector https://en.wikipedia.org/wiki/DIN_connector it still would be compact, smaller than type F

is TRPV3 even involved in any way because last time i’ve checked some of best evidence points in direction of TrkB

UK uses type G. Type E/F plug has both contact for grounding pin like in type E and two sliding ground contacts on side like in type F. Sockets are either E or F, and i’ve mostly seen E

no, because it’ll just trip fuse, and stoves are wired directly anyway

C/E/F also have shutters, probably more types do that too

Type E and F plugs are not really a thing anymore, today it’s more common to find combined Type E/F plugs.

Fuses in british plugs are a mistake and only a requirement because of sketchy practices allowed in british electrical code immediately after WW2. Nobody else does that because nowhere else electric code is built in such a way that it is necessary. Switch seems to be mildly useful tho

with wood, the problem was with lignin which is tightly crosslinked, meaning that it’s insoluble and organism willing to eat it has to secrete some enzymes to break it down in smaller bits that can be absorbed

depending on plastic, this first step might be easier or even happening on its own. there are already bacteria that feed on nylon but nylon starting materials are easier to digest for them

llms allowed them to glide all the way to the point of failure without learning anything

Live in the forest ig. Some defect to Ukrainians, there are flyers and websites and telegram channels for that, but hard to say how many choose so
