  • 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.





  • 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.




  • 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.




  • Another solution I’ve played around with, but it didn’t work super well… would be krfb-virtualmonitor

    KDE’s remote framebuffer tool for making a virtual monitor to VNC into. For me it didnt do what i wanted because I have 3 other monitors and I couldn’t assure that things would launch directly into the virtual monitor… and it doesnt support any sort of dynamic resizing… But there might be something there.

    I also hope that this kind of stuff improves in the future because of the Steam Frame. In Tested’s video, he calls out that he can only stream games at 21:9 if his 21:9 monitor is on. And other VR friends have pointed out the desire to dynamically resize content in the headset. So maybe this will get better in the future.

    For me the issue is that i have a OLED 21:9 desktop, and streaming to my Steam Deck risks burn in on my desktop, and annoying black bars on my steam deck… I’d love to just have a 1280x800 faux monitor to stream to my steam deck, nothing needs to be visible on the desktop (headless, like you want).

    But anyway tl;dr - krfb-virtualmonitor vaguely worked but not for what i needed. Virtual monitors are definitely a possibility



  • The market demand they are filling is cutting in line. Every time a scalper buys an item, a legitimate customer doesn’t get it. So genuinely SOMEONE is not getting a steam frame because of a scalper. That’s how it works. The steam frames being sold on ebay aren’t just magically generated by scalpers, they are the result of someone else getting pushed out of line.

    Supply isn’t increasing because of them.
