In the gmail web client, I dont see an option to filter off headers. thunderbird lets you set up filters for custom headers, but it's a bit more complicated.

TBH, i never used it to set up a custom filter, I just knew there were indicators I could use to figure out if an email was in fact a test

    Apparently I'm both right and wrong.

    At a previous job, there was a header. I can't remember it directly, but lets say it was like this:

    X-Acme-Security-Test: Authorized simulated phishing exercise conducted by KnowBe4 on behalf of Acme Corp for security awareness training and compliance validation
    

    Apparently KnowBe4 lets customers set their own custom headers. So this was probably set by my company. And not something everyone will see.

    But also, they set an X-PHISHTEST header. Maybe its a signed header, so they can cryptographically prove the test was in accordance with the customer's request (this email was sent by us, but it uses YOUR private key, so clearly you were involved here, and we arent just scamming people, or otherwise allows you to validate it at the firewall/spam filter). This isn't the header I remember, but apparentlly can also be used to detect them -- the explicitly say not to do that, but here we are.

    But if you ever get a knowbe4 phishing test, check the email headers. you'll probably find something to key off of.

    Generating a list of books isn't hard or impressive. Taking the known cover art for those books and displaying it in a layout doesn't require fancy ai either.

    Also not sure why you'd want this beyond just the list

    Indeed. My point wasn't that wind is better than solar. But having both is nice. Solar isn't available 100% of the time, and if the periods of low solar are longer than battery capacity, then you wind up back on the grid.

    Diversifying your power sources means that even if it's cloudy, you still have wind. Is it a good idea financially? No. Is it a good idea if you are committed to the idea of maximizing time off the grid, yeah. Cost per kWh isn't the only factor in why someone might want home power.

    "But Apple did it with absolutely 0 consequences"

    I don't think it's a super common sentiment across all crowds, but I wouldn't be surprised if some groups see the benefits Apple got by switching and wanted that for themselves.

    One of the benefits is only needing to have 64 bit libraries. With this change most people can drop their 32 bit stuff.

    Bits are literally "binary digits". So more bits means bigger numbers. The reason you get more memory, is because when the code says "put this data in memory spot (number bigger than 32 bits)" .. you cant with only 32 bits. How do you represent that number.

    Imagine that you want to put something in memory spot 150, but you only have 2 digits. You cant. Bumping it up to 4 digits, you can say "put this data in memory address 0150" and its fine. "bigger numbers == more addresses == more places to put stuff"

    So anywhere you need a number bigger than 32 bit represents, you can either just use a 64 bit number, or do a bunch of shenanigans. Those shenanigans require extra calculations inevitably. https://en.wikipedia.org/wiki/2,147,483,647 If youve ever seen this number before, it's probably because of a 32 bit limitation. It shows up all sorts of weird ways.

    Bigger numbers here aren't about taking up more space, just representing literally bigger numbers. "9999" only takes up 2x as much "space" as "99" but it repesents a number ~100x bigger.

    Sorry, I'm tired and rambling.
