Wd40 is a solvent.
It happens to lubricate and protect from water for a short time. But if you use it as a lube, you are gonna have a bad time.

Use wd40 to loosen something up, clean off old grease/oil/gunk, protect short term from flash rust etc.
Then actually wipe it down and lubricate it with a proper lube

    Yeh, it was COVID that went after republicans.
    It wasn't republicans that politicised COVID and rejected medicine and science.
    It wasn't republicans listening to republican politicians who called it a hoax, and ignored scientific/medical recommendations.
    It wasn't COVID that was politicised.
    COVID was created as a political tool to go after specifically American republicans.

    (That's all sarcasm.
    COVID doesn't care about your beliefs. It tried to infect nearly everyone. The resistance to being infected is social distancing, masks and vaccines. All of which are super effective. As proven by the fact that the US is no longer losing a 9/11-worth of people PER DAY and the fact that society is mostly back to normal)

    The articles relate to tracking behaviour (IE watching TV, playing video games, cooking, showering, sleeping, out & about), not deciphering what your computer is doing.
    Maybe they can tell if you are just browsing the internet, or if you are playing video games. But you could just as easily be training AI models, rendering some animations, 3d modelling or mining buttcoin.
    The articles allude to "knowing it's a computer being used" because the noise of it's PSU is different than lightbulbs or fridges.

    Data centers use UPS battery banks to provide persistent power during a power outage to cover the gap before backup generators start up.
    Data centers use power smoothing systems to protect wiring and switch gear, as well as fixing the Power Factor - which will drastically reduce their electricity bill.

    The power required to generate 00001111 Vs 11110000 is the same from an outside perspective. 4 bits on, 4 bits off. And computers have a word size of 64 bits. That's a lot of permutations that a miniscule ripple in current might indicate.
    And all ICs in a computer will have local decoupling caps (because the same power noise that "can be decoded by a power meter" interferes with the ICs, so it is filtered).
    And the the SMPS will have some chonky smoothing caps, and the MOSFETs chopping that at 100kHz or whatever. Lots of smoothing, and lots of more significant noise sources.
    Nothing upstream of the PSU is going to be able to read what's going on inside a PC, other than "it's drawing a few watts more".

    Now, maybe there are security minded companies that take things to the extreme.
    Having a central DC power system that powers 100s of servers has the benefit of mixing all that potential noise together into an even more incomprehensible noise.
    So, I can see some companies spending tens of thousands more just in case someone manages to break physics. Because 20k on an install could save millions later.
    But if they are paying that much attention to the data security of power, I hope it's an air gapped system.
    Or they've been sold some snake oil.

    Seriously, noise on the power is not a data security issue.
    It is a privacy issue if power companies are tracking it that closely, because they can model your behaviour.
    Which is what the articles are talking about

    I was gonna make up some bullshit quote of cutting red tape to allow the economy to flourish. Cause from the headline alone, it could easily exist or it would be suitably satirical.
    But I read the article...

    “The Department of Labor is proud to lead the way by eliminating unnecessary regulations that stifle growth and limit opportunity,” Secretary of Labor Lori Chavez-DeRemer said in a statement, which boasted the “most ambitious proposal to slash red tape of any department across the federal government.”

    ✅ Slash red tape.
    ✅ Unnecessary regulations.
    ✅ ✅ That stifle growth.
    ✅ ✅ And limit opportunity.

    Covers all the points I would have satirically made.

    Some of you may die, but think of the 📈 stonks

    Offset, not solve.
    They pollute, but don't want to have to deal with fixing it.
    So they buy other pollution (easier & cheaper to deal with than their own pollution) and "dispose" of it.

    Like carbon offsets. Planting trees offsets co2 pollution. So polluters can keep on pumping out co2 as long as they plant enough trees.
