  • Is it? There seems to be widespread agreement on that point, here on Lemmy, that expecting the worst of everyone is critical to motivate the Americans to go out and vote.

    It’s a strong enough consensus, reinforced with absolute certainty over and over in our political communities, that I’ve been forced to ponder it myself many times. Because I also have an instinct that it’s quite possible to demotivate and even deactivate would-be voters by making them feel that theirs is a lone flame in the wind, or that the insurmountable forces of evil will make their efforts inconsequential.

    As a counter example, here in New York, that wasn’t what brought people out to knock on doors and vote for the new progressive mayor. People participated because they had hope for change, or maybe just to be a part of a something new. They weren’t voting against Cuomo as much as they were voting for Mamdani, if that makes sense.

    Are we confident that our all-in commitment to motivating people through fear of their neighbors’ inaction is a winning strategy?

    Dear colleague,

    By qualification I meant explanation. My doctorate is irrelevant to the truth.

    Since you asked, my larger point was about the unhelpful nature of this content, which makes students of math feel inordinately inferior or superior hinged entirely on a single point of familiarity. I don’t handle early math education, but many of my students arrive with baggage from it that hinders their progress, leading me to suspect that early math education sometimes discourages students unnecessarily. In particular, these gotcha-style math memes IMO deepen students’ belief that they’re just bad at math. Hence my dislike of them.

    Re: Dave Peterson, I’ll need to read more about this debate regarding the history of notation and I’ll search for the “proven rules” you mentioned (proofs mean something very specific to me and I can’t yet imagine what that looks like WRT order of operations).

    If what riled you up was my use of the word “conventions” I can use another, but note that conventions aren’t necessarily “optional” when being understood is essential. Where one places a comma in writing can radically change the meaning of a sentence, for example. My greater point however has nothing to do with that. Here I am only concerned about the next generation of maths student and how viral content like this can discourage them unnecessarily.






  • Right, and that clue IMO unravels the more troubling aspect of why this content spreads so quickly:

    It’s deliberately aimed at people with a rudimentary math education who can be made to feel far superior to others who, in spite of having roughly the same level of proficiency, are missing/forgetting a single fact that has a disproportionate effect on the result they expect.

    That is, it’s blue-dress-level contentious engagement bait for anyone with low math skills, whether or not they remember PEMDAS.

    Honestly that’s my pet peeve about this category of content. Over the years I’ve seen (at least) hundreds of these check-out-how-bad-at-math-everyone-is posts and it’s nearly always order of operations related. Apparently, a bunch of people forgot (or just never learned) PEMDAS.

    Now, having an agreed-upon convention absolutely matters for arriving at expected computational outcomes, but we call it a convention for a reason: it’s not a “correct” vs “incorrect” principle of mathematics. It’s just a rule we agreed upon to allow consistent results.

    So any good math educator will be clear on this. If you know the PEMDAS convention already, that’s good, since it’s by far the most common today. But if you don’t yet, don’t worry. It doesn’t mean you’re too dumb to math. With a bit of practice, you won’t even have to remember the acronym.



  • Edit: I wasn’t actually disagreeing with the comment above. You should downvote me too.

    Board of directors

    Correct. The board defines the company, not the CEO.

    CEOs are usually puppets. Whatever role they play, you can bet they were hired specifically to play it, and were incentivized to stick to the script.

    Their job (legally, their fiduciary obligation) is to maximize shareholder value, to take the credit or blame, and fuck off.

    The board (typically key stakeholders) are so pleased when the public focuses on their CEOs, even if it’s for their shitty opinions, behavior, or obnoxious salaries.

    Because the worst thing that could happen to them would be for the public eye to actually follow the money, and it’s easy to see why.

    If the rabble truly fathomed just how many of those “golden parachutes” stakeholders stockpile with every disgraced CEO, however ceremoniously disavowed…

    Accountability would shift to more permanent targets yes but, more importantly, it would quickly become common knowledge that, all this time, there were in fact more than enough golden parachutes to go around.




  • For example the tools for the really tedious stuff, like large codebase refactoring for style keeping, naming convention adherence, all kinds of code smells, whatever. Lots of those tools have gotten ML upgrades and are a lot smarter and more powerful than what I remember from a decade ago (intellisense, jetbrains helper functions, various opinionated linter toolchains, and so forth).

    While I’ve only experimented a little with some the more explicitly generative LLM-based coding assistant plugins, I’ve been impressed (and a little spooked) at how good they often were at guessing what I’m doing way before I finished doing it.

    I haven’t used the prompt-based LLMs at all, because I’m just not used to it, but I’ve watched nearby devs use them for stuff like manipulating a bunch of files in a repeated pattern, breaking up a spaghetti method into reusable functions, or giving a descriptive overview of some gnarly undocumented legacy code. They seem pretty damn useful.

    I’ll integrate the prompt-based tools once I can host them locally.
