    Not that long ago, I only graduated last year. I’ve definitely noticed the tweaks-between-editions bs, so I always try to match up the isbn. I was also lucky in that I only had to deal with the online course/book bundle for general math courses, most of which I took care of in highschool and were paid for by the school, but yeah I did have to cough up one to two hundred bucks for a few of those.


  • I wouldn’t be too hard on yourself, kids are weird in that they can have huge blindspots in their empathy because they’re too young to have had to wear another person’s shoes, so to speak. By the time you’re an adult, either you’ve gone through enough shoes to become a well-adjusted, empathetic person, …or not. But even then, we all have blind spots we can improve on.

    So if anything, putting yourself in another person’s/bug’s shoes like you describe in the comment is proactive and should be lauded if you ask me. Lots of people don’t seem to gain empathy until they’re the ones on the other end. Hell, I don’t know you, but consider that maybe you being self-conscious about your capacity for empathy is ironically out of your empathy for the people you interact with. If you really had no empathy, then why would you care?

    I always pirated PDFs of my textbooks, but in the few cases where I couldn’t find anything online (typically when the book is niche and very new), I would always wait until I knew that I actually needed the book, because it was frustrating how often this meme came true.

    I had this one professor I was really grateful for though. He was a big open-source guy, apparently used to contribute to freebsd and postgres, and he went out of his way to find open-source textbooks for all of his classes.





  • I don’t use tiktok, I’ve never been interested in using tiktok, and if it was just going out of business or something then I would give precisely zero fuckaroos.

    But I don’t need the government making the decision to block it for me arbitrarily. I confess that I’m not studied up on the reasoning behind blocking it (I’ve mostly heard about security concerns), but if Congress and the supreme court actually cared about digital security, then they’d be passing a bill of digital rights right now. Instead of doing that, they’re set on going after TikTok specifically, which tells us two things:

    • Because they aren’t passing blanket digital privacy rights, it’s likely that TikTok is not the only company committing these privacy violations, but they don’t want to punish the “wrong” company.
    • Given the previous point, it follows that they don’t actually care about digital privacy (duh), so the actual reason for banning them is likely something else. Other people in this thread have pointed out that the US government can’t control propaganda on TikTok like they can other social media, but it could also be as simple as clearing the way for American competitors/lobbyists who stand to profit from the ban.

    So yeah, like you I don’t use tiktok so I’m not directly affected by the ban, I might’ve even supported it if it was due to an impartial bill of digital rights, but reasoning behind the actual ban is clearly bullshit on principle just by being so specific, and it sets a dangerous precedent. You saying that TikTok is shit so you don’t care if it gets injustly and unconstitutionally banned is no different then saying that George Floyd was a criminal so you don’t care if he was murdered by cops sans-due-process. You’re being distracted, soulifix. Think about it, if the government cared about addressing the issues with TikTok that you brought up in your post, why are they going after TikTok specifically instead of addressing that behavior generally?


  • TL;DR you can’t use infinity like that and your calculus professor will yell at you if you try.

    Infinity isn’t a real number and it’s not generally useful to think of it as one like the dude in this comic is trying to. However, in calculus you can treat it as a concept that a variable or expression can approach. In that way, “approaching infinity” is just another way of saying “increasing forever” or “given a number x, you can always use x+1”. This is why expressions like “infinity = infinity" or “infinity = infinity+1” like the comic are not useful statements.

    That’s also why your calculus professor is so insistent that you write out the whole limit notation, because it’s nonsense to just throw infinity into an expression raw (like “infinity+1” in the comic). But, if you think of it as “the limit of x+1, where x approaches infinity”, then it’s clear that infinity doesn’t have anything to do with the actual values, it’s just used to describe potential values.

    Here’s an example if that still doesn’t make sense: Bob and Jill are twins who were born with 0 and 1 dollars respectfully, but both earn a dollar a day forever because they’re immortal. Just because they will live forever, doesn’t mean that they’ll ever be able to say “I’m infinite years old”. They’ll always be x years old, but x will increase by one every year from their birthday for the rest of time. For the same reasons, they’ll never be able to say “I have infinite money”, but if they don’t spend it, it will increase forever, approaching infinity. And finally, if neither Bob or Jill spends anything and that dollar a day is their only income, then Jill will always be worth a dollar more than Bob, even though both have infinite wealth potential.
