  • I thank you for your engagement. If you’ll indulge me further, please read on. The units you’ve measured in are irrelevant. We live in the same universe, and units are perfectly interchangeable (though, some systems are more internally consistent than others…)

    This is a solved problem, may I introduce: constants.

    PV=znRT is most certainly a formula derived from experiments.

    R, is the gas constant, it’s a value with units :O

    (For example 8.314 m3⋅Pa⋅K−1⋅mol−1)

    (Many, many constants in formulas have units. It’s just engineers being weirdos specifying variable units instead)

    My point is to stop making me look up the units on a different page. Variables should not have specified units. It’s never necessary (possibly some edge case I haven’t considered?)

    Constants should have specified units.

    Translating them into a constant introduces no inaccuracies, it’s just multiplication.

    I could be a weirdo and say P⋅V=z⋅n⋅8.314⋅T and make you look up on another page what the units are (grumble), oooor you could just specify your constant units so that the user can either convert their units to something suitable for the constant, or more easily convert the constant into the units they want. Forcing the user to first derive the constant by referring to another page is frustrating.

    That’s how the gas law equation (from above) works. The gas constant has units, and you can quickly look up whichever variation to want to save time, or convert it yourself if you’re using a particular set of units all the time that’s not common enough to be on the Wikipedia list.

    For the gas law, this formula is super basic, so many know it like the back of their hand. But in engineering there are all sorts of approximations out there with all sorts of complicated equation forms that you need to keep referring back to.

    Just give me the constant with units, gaddamn.

    My gripe from the the original post exemplifies this. The Crane TP 410 has a factor of 32000 because of the units being baked in. And for what?

    I know I’m onto something here because I have anecdotal evidence it confuses people. The calculation template my company uses for pump sizing was doing some bizarre conversion first into imperial, then into metric, all because they must have thought they had to use the formula as written (they had used a different version of the reference I was talking about, written in imperial units).

    Sooooooo dumb, because in this case, the constant is dimensionless. The constant is just 32. The formula should be written the same, regardless of imperial or metric units, but it isn’t.

    We don’t need two formulas for two different sets of units. Formula should remain exactly the same, only the constant should change.

    And when the constant is dimensionless, even more so.

    Thanks for coming to my TED Talk :)






  • Lol, if it’s gonna happen, can it really get underway in the next 3 weeks?

    The Australian Labor party could ride its credentials from the previous recession, which we basically came out of unscathed, into another term of government. Anything to avoid the Libs (the conservatives, confusingly for everyone else outside Australia).

    Might be a bit of a stretch though, since we won’t be able to sell as much raw materials to China as we did back then.

    Anything to keep the Libs out of power, pls.

    It’s crazy that people thought Trump’s plans were a good idea. Or that they still do, even now.








  • Thank you! Drives me up the wall that when people suggest this and they haven’t thought it through, and that it might make other things worse.

    I’d say for everyday usability, what we have is way better. Sure, you deal with timezones, but at least once you know what time it is there you have a good sense of what part of the day they are in.

    Currently you look up the timezone, maybe do some maths (but let’s be real, you just search and get given the time) and then you immediately have a good sense of what the time is there, oh cool it’s 7AM.

    If we all had the same timezone: you look it up, and then you HAVE to do maths. Why? Oh their midnight is 8, and it’s 15 now, so 7 hours after midnight.

    Your mind immediately has gone to oh it’s 7AM, but NO, in this new reality, it’s 15:00 everywhere and where you live midnight is 14:00, so that means where you live it would be like your 21:00.

    No matter what time you pick to anchor what time of day that place is, the problem persists. And now you just have replaced the problem of looking up timezones, with looking up when the sun is at some point, and then needing to convert that to get a sense of what time it is there according to the sun.

    This would be shit, when you get to a new country when travelling you have to relearn what the numbers “feel” like.

    Let’s just keep what we have, this is a solved problem.





  • Yeah, Australian system is currently trash, but only because we’ve let things slide back towards private health, not because a single payer system is not simple. It’s only complex because private health is encroaching and government funding is waning. If we actually had a single payer system it would be simpler (but we don’t actually).

    So many low cost GPs and other health services are needing to charge more because the rebate is way too low.

    Plus, in my opinion, some price gouging by some areas, by some (psychologists come to mind for recent crazy price inflation)

    Get rid of private health, and we can just pay our insurance premiums to the government, and actually be guaranteed care, not this stupid tiered nonsense.

    Dental, optical, and all these other “extras” should just be provided. We’re one of the richest countries per capita in the world, it’s embarrassing.


  • I very much appreciate your last sentence.

    Medicare is a sad shell of its former self, good luck seeing a GP or a specialist for free these days. Want a specialist to check out your breasts? That’ll be $400 for the first visit and $210 out of pocket for all your follow ups, $800 (out of pocket) just for a biopsy if you need it. (Rough numbers from a friend). And consider that most women develop some kind of breast growths in their life time.

    Sure it’s not US levels of price gouging, but heck. Medicare is being lost and we’re not fighting for it.

    I won’t be satisfied until private health is dead. Fuck private health.


  • As a non-software engineer, feels weird that they’re making this distinction.

    I don’t have much to do with engines either.

    I take engineer to mean: designs stuff that does some task, involving SOME kind of calculation.

    Visual designer: not an engineer

    Piping designer: not an engineer (although this one felt weird, that’s what the piping designer corrected me to say, so)

    Chemical engineer: ya

    Mechanical engineer: yeah

    Software engineer: totally different flavour, but still yeah

    Language is what we want it to be.

    Web designers presumably still need to script things, I reckon that counts 👍
