  • If the rise time isn’t 0, it’s not a square wave.

    And if that’s your definition then there’s no such thing as a real square wave.

    Just like no physical objects can have a perfectly square corner, there will always be some radius, even if it’s just 1 atom

    The reason making a true square wave is hard is that there are physical properties of real life electrical components that prevent voltage (or current) from changing instantly. Similar to how we can’t instantly accelerate a mass from 0 to some speed, it’s physically impossible. The faster you try to do it, the harder it is due to inertia. In electronics, there’s always natural capacitance and inductance slowing things down. If you want a 10v square wave, you have to push some amount of electrons through some amount of capacitance and inductance and that, while it can be very fast, is never instant.

    Lmao idk if “most” even holds up in fiction. Even the “good” cops in fiction tend to perform illegal searches, abuse suspects, break the law in countless ways to get the bad guys. How many times have we seen the “good guys” stymied by their inability to search a home but one turns to the other and sarcastically says “oh I think I heard someone scream for help lol” kicks down the door?

    Sometimes they have a conscience but I’d call very few fictional cops “good”



  • This gets posted occasionally and while I agree, the subscription for an airbag is one of the dumbest things ever, it’s not the only way to buy the thing.

    It’s available as a one-time purchase instead, which obviously is what everyone here would choose, but it’s a fairly high price, and their argument for offering a subscription model is that they want the price barrier for safety equipment to be lower. There are other ways to do it, but the option of a subscription is fine IMO as long as the one time purchase remains as well.








  • There’s accepting randomness on one hand, but on the other hand dnd is also about player creativity and DM interpretation. In tabletop DND I can say whatever I want, not limited to a couple of unclear choices and Attack

    Several times I’ve been presented with a dialogue that I have no options that I’d actually choose. One such example was the equivalent of “absolutely, I’ll go fight them for you” vs “no, I won’t fight them for you. FIGHT ME” and nothing else. In tabletop you can ask "can I do something else for you?"or say Sorry, I’m not strong enough, or you can TELL YOUR PARTY YOU WERE LYING. If I get pigeonholed by the dialogue tree, I’ll absolutely load a savefile and choose something else, even if that means rerolling a failed persuasion.

    In the end I feel like it’s made up for by the amount of times I get unfairly screwed by clicking an invisible wall that the cameras looking through a d my character dies because they walk through a trap blasting em off a cliff or something.
