    I wouldn’t jump on to blame on the customer. In fact, have my own hill I’m fighting right now where I’m not completely in the right. Who knows, maybe the working hours were not visible, or maybe there was no closed sign at all. In any case, this made at least one person mad and is a perfect opportunity for a business to do a retro and check if they might need to do something about it. It’s much more valuable than a thousandth review from someone who had a great time… or didn’t, but didn’t care to review either. And, unless your business is genuinely bad, even a Karen once in a while shouldn’t affect the total score a bit.

    Not necessarily. Even though PS/2 operates with a superior protocol, latency-wise, the clock speed is atrocious, resulting in an effective polling rate of about 1500hz, give or take. We could account that it doesn’t need to wait for request to send keystrokes like USB keyboard do, effectively doubling it even more, but then we’d have to account for whatever delay Super I/O chips introduce and I’m not qualified to talk about that. But, if your keyboard is not from a dollar store shelf then it probably runs on at least 1000hz, at which point we are talking about sub-millisecond differences which would be quite hard to notice. 4000hz keyboard definitely beats PS/2 though.



  • It’s actually the other way around. Check out Ben Eater’s awesome videos for technical details.

    TLDR: PS/2 sends separate key up and key down events, sequentially - like #1 Down - #2 Down - #1 Up - #2 Up - each in separate message, allowing for theoretically infinite rollover (excluding certain edge-cases). USB, on the other hand, polls only for keys being pressed at the moment. By default, the keyboard responds with a 8-byte message, with 1 byte being the bitmask for 8 modifier keys (4 on each side), a spacer, and 6 bytes/slots for identifiers of keys being held down. If one identifier is present in one response but is missing or replaced in next one, the system assumes a key-up event. It is possible by USB spec to negotiate connection in such a way that the keyboard responds with a bitmask for every single key it has. But this is not well supported by things like BIOS and KVM’s, so very few keyboard manufacturers bother implementing it. Most keyboarrds advertising NKRO are actually only capable of doing so via the PS/2 adapter.



  • Might have some trouble if it’s a typec dock and the monitors are connected to it. Laptop’s own outputs might also be wonky if there’s a hybrid gpu setup going on, but support for thosr has improved a ton lately. Mkb should work fine out of the box as long as it’s not some unified proprietary bullshit wireless kit with smarfridge integration.

    Overall, I would suggest just ripping an image of ubuntu, or pop_os if you got nvidia card, boot off it, just close the installer to try live mode, and see for yourself if everything works. Takes like an hour to do, no installation required. You can even install software, except gpu drivers, as everything would be all wiped on reboot and gpu drivers need reboot, hence popos suggestion as it has them built-in. You can try remmina on it - it’s the most common remote control software, supports both rdp and vnc and a bunch of other obscure protocols.









  • Exactly! I rant about this a lot, but I know at least couple of people who run with laptops that have broken audio. As it turns out, installing sound card drivers is not really an option as the janky-ass drivers that the manufacturers put out nowadays can irreparably brick your entire system. It is beyond my understanding why recovery, restore, and even safe mode would even try to load them in the first place, but, apparently they do, and then crash before you could even do anything, leaving re-install as the only option.

    Meanwhile, I rm -rf-ed my /boot directory the other day, and then df-ed a couple gigs of /dev/zero straight into /dev/sda. Got it back up running in just a few hours… of kicking myself for why would I do such a stupid thing.
