  • That is a completely separate issue from the above commenter.

    You absolutely cannot get 2FA authenticator codes from 90% of services

    A shockingly large amount of companies demand phone numbers and send verification texts before allowing you to do business with them, to create an account, to recover an account, to delete an account, to place an order, etc.

    They really shouldn’t, it’s a bad security practice but companies love it because with a phone number they can lower support costs by just allowing people to do a self-service where they get an automated text and can unlock their locked account.

    Also an issue, but indeed a separate issue from using unsecure SMS as TOTP.

    Lol, you literally quoted me, didn’t actually read what you quoted, and then did something completely different.

    Do you know that battery life ≠ battery capacity? That is not the same measurement as I have already tried to teach you 3 times.

    Please state the calculation that you would use to “determine how often you have to recharge” that is valid for Wh and not for Ah.

    What is its idle power draw? What is its power draw under load? Playing video? Sleep mode? That source gives nothing which determines battery life. All it gives is a nearly useless capacity number, just like all other manufacturers. So not valid at all. You still have exactly 0 more information about battery life.

    If I am wrong, please state your calculations of what the battery life is with that 54Wh battery.

    Your entire argument was “Ah is useless and Wh gives consumers the information to determine battery life” So go ahead, determine the battery life.

    How is this any different at all if they said that it is a 5.8Ah battery? They don’t give any current or power draw.

    As an exercise:

    can you tell me the battery life difference between an arbitrary Laptop A with a 54Wh battery and Laptop B with a 27Wh battery?

    Please explain to me what the difference is between battery life if you have a 5000mAh battery and an 18Wh battery.

    Please state the calculation that you would use to “determine how often you have to recharge” that is valid for Wh and not for Ah. I am all for it. If you can cite a single source where the manufacturer gives a specification that would give battery life in Wh, and not in Ah, I will concede the entire argument and say that you were right the whole time in every comment make a note that you were right. Please show your calculation work.

    The thing is, it does not matter how much charge the battery holds, it does matter how much energy it holds. Without knowing the Voltage the Ah is useless.

    This is patently, objectively misinformation and completely false. That is a direct quote of your words, today. That was your last comment. I have already laid out multiple examples of how Ah is a useful measurement and what you can do with it. Therefore, it is misinformation. It is not disinformation, but stating untrue things as fact is misinformation, even if you have no idea you are wrong.

    Sorry, but you are simply wrong. Simple math says that you are wrong.

    You can buck or boost convert nearly any voltage to any other voltage.

    Then measure the current output of the battery, boom you have battery life.

    Also electrical charge can be used in many, many very valuable calculations without involving voltage at all.

    Let’s take an arbitrary example with an arbitrary battery powered device. Let’s say the battery is somewhere between 1V and 10000000V. You can’t measure it because you might blow up your multimeter.

    You know that the battery is 5000mAh. You can safely measure that all of the circuitry is draining 1000mA because sense resistors or contactless magnetic current measurements don’t have anywhere near dangerous voltages. You know that the battery will last about 5 hours. What is the voltage? Doesn’t matter.

    Yes, charge and the flow of charge is not the entire story, but to say it is useless or does not matter is just a straight lie. It is fine if you don’t understand electronics, but then don’t spit out misinformation.

    Yes Watt-hours would give a more complete picture to slightly tech-inclined consumers (makes 0 difference for 99% of consumers), but then it returns to not mattering because you can do the 5s calculation yourself because single cell lithium batteries are overwhelmingly 1 nominal voltage.

    Literally 90% of calculations related to efficiency are JUST as valid using mA as W.

    Your device uses 12mA at idle with a 5000mAh battery has the same relevance as your 18.5Wh battery using 45mW at idle.

    I believe it actually has to do more with historical conventions in electronics or math. (This is just what I remember from heresay when I was in university as an electronics engineer), but there is also a mathematical reason.

    history hearsay theory

    The easiest way to measure power draw is by measuring current draw (voltage across a sense resistor) way back before there were affordable, quality ICs to measure voltage and current and pretty much joule count.

    To add to this, current sensors are much easier and cheaper than test machines that do the calculations for you.

    When lithium batteries and NiCAD batteries became standard compared to the earlier lead-acid (which are measured in Wh), they had an extremely flat voltage curve compared to lead acid. They could be considered to be at a constant voltage.

    Now cheaper electronics were being made and if a designer wanted to know how long a battery would last, they could take the nominal battery voltage that the battery would be at a vast majority of the time, and they could just measure the current draw over a short time of the circuit, 10s of calculations, and you have your approximate battery life. There is a joke that engineers approximate π to 3.

    Even designing electronics today, everything is specced to current draw, not power draw. ICs take X current in mA during Y operations. Your DCDC converters have Z quiescent currents and from there you can calculate efficiency. It is much easier to work in current for energy running through the circuit.

    Math units

    Ah is a measure of electrical charge.

    Wh is a measure of energy

    Batteries and capacitors hold charge so are measured in Ah, generators that power the grid generate energy and use of that energy is measured in Wh (it also isn’t a “constant” voltage source like batteries as it is AC)



  • Then what about when they constantly refer to the rhetoric as “truth” how Ukraine was full of Nazis that were genociding the Russian minority and how Russia invaded to save them and has committed exactly 0 war crimes?

    I completely get that the US is not a good guy, most of western civilization was built on exploitation, imperialism, and subjugation of people. I even understand the great things China has done as far as huge quality of life upgrades for their people.

    But Russia is only similar to china in that they propagate huge anti-US propaganda and technically support each other as an anti-US coalition.

    Russia is also extremely imperialist, always has been, and literally has annexed (or tried to) multiple nations in the past decades, and is currently trying to do the same. Russia is everything that hexbear stands against, yet they unequivocally support them without any doubt.

    Go say literally any critical things of Russia in hexbear. You will 100% be down voted to oblivion, if not banned. If you say anything against Putin being the greatest leader in recent history, you will be down voted to hell if not banned. I have yet to see any critical speech of Russia on hexbear that didn’t get removed or down voted so hard that the comment will never see the light of day.

    I understand being Anti-US, but if Russia was in the US’s position, they would be just as bad if not worse for the treatment of people and propagating imperialism. Then to censor people about it… I can scream on other instances about how stupid the US is until I pass out and I wouldn’t get banned. That is TruthSocial/theDonald/Twitter territory.


  • Maybe you can clear this up then:

    Why does everyone there unequivocally, wholeheartedly, unquestionably support Russia?

    Russia has barely a trace of communism anymore and it is hard right oligarchy that fits almost every definition of fascism. Not to mention HEAVILY racist and anti-LGBTQ (I have multiple friends who were from Russia and they were the ones who originally told me that before I saw it for myself in Russia)

    Yet the “antifa” hexbear will literally down vote you to hell and ban you if you say anything even slightly bad about Russia.

    Also news@hexbear is 80% articles about the war with everyone citing Russian propaganda as absolute truth and every western media, every human rights group, etc… is completely lying about the war.

    An interesting juxtaposition as they are in the same way pro Palestine and cite those human rights groups as telling the absolute truth in that case






  • And in all tiers: make an additional profit by selling your information without your consent (it has been decided in many courts that burying subtext deeply in forced terms of service isn’t consent)

    We are already paying them by letting them harvest our data, ads or not.

    Then they double or triple dip with the scenarios you describe. I am still paying them by being on their site with an ad blocker as they harvest my data and sell it to the highest bidder. Not to mention quadruple dipping with using our info and content without consent to train AI to sell.

    They use the argument “your data/art/photos/videos are freely posted on the internet, so we can use them how we please”. If they publish content openly on the internet, then we are free to do with it as we please.

    They can’t use the argument but say “no no no, it doesn’t apply to things WE put out”

    They are either pirating our content and data constantly or ad-blocking is not pirating.



  • I am fighting this with people at work.

    No, it is not “one more password to remember”

    You have 2 passwords: your laptop and your Bitwarden. Forget everything else. Don’t care. Use a passphrase if you have troubles with passwords.

    I even generated a sample password from bitwarden and drew them a picture of how to remember it lol

    Still about 10% of people forgot their password in the first 2 months.
