Copyright is far too long and should only last at most 20 years.
Actually, George Washington would agree with me if he was still alive. He and the other founding fathers created the notion of copyright, which was to last 14 years. Then big corporations changed the laws in their favor.
Hot extreme opinion: copyright shouldn’t exist, and authors should be covered by other means, particularly public funding based on usage numbers and donations.
Chick-fil-A isn’t that great.

Myers Briggs is posh astrology.
This should be a popular opinion honestly, because it’s correct.
It shouldn’t be taken as scientific truth but it can help you know yourself and others better, and it’s an insult to compare it to astrology because at least it’s not based on completely random things like the position of the planets when you were born. The issue is that most people only know MBTI as online tests, which are self-report and have extremely vague and stereotypical questions that can very easily be manipulated to get whatever result you want, with the worst offender being the most popular one, 16personalities, which isn’t even an actual MBTI test but a BIg 5 one (which is not to say Big 5 is bad, but it’s very misleading to map it to MBTI types). In reality to use MBTI somewhat effectively is going to take studying Carl Jung’s work, how MBTI builds on that, lots of introspection, asking people about yourself, and lots of doubting and double checking your thinking. And very importantly you have to accept that in the end this all isn’t real and just a way to conceptualize different aspects of our personalities and it’s in no way predictive, you have to let go of stereotypes, anyone can act in any way, it’s just about tendencies.
This is insulting to astrology, but yes lol
I used to think this, but I think the new posh astrology is mental disorders in general. It costs thousands of dollars to get professionally assessed, whereas MBTI is a free quiz online. Crippling anxiety, depression, OCD, panic attacks, etc., are the new ENFP
Jesus this is a bad take
I think that’s actually been proven at this point hasn’t it?
That doesn’t stop an absolute fuck ton of people believing in it. One of my friends is quite deeply into it, she’s in FB groups about it, and decides what everyone’s type is upon meeting them. According to her I only think it’s nonsense because I’ve only done the free online tests, not the proper one. She wouldn’t listen the other day when I tried to put her right about flouride in the water, either.
Sounds like the test itself isn’t the problem but how it’s used and how much people attach to the results, like with IQ tests. Neither that nor Myers-Briggs should be part of interviewing for a job either but apparently some US companies do it anyway.
No, the test itself is definitely the problem. Regardless of whether you believe a personality type test can be effective, the MBTI is particularly and provably ineffective in just about every measurable way:
It’s not reliable. It has terrible test-retest reliability. If I’m X personality type, I shouldn’t test as X type one time, and Y type the next, and Z 6 months laters.
It’s not predictive. If a personality test accurately judges someone, it should mean you now know something about someone’s behaviours, and can extrapolate that forwards and predict behavioural trends. MBTI does not.
It fundamentally doesn’t match the data. MBTI relies upon the idea that people fall neatly into binary buckets (introverted vs extroverted, thinking vs feeling, etc). But the majority of people don’t, and test with MBTI scores close to the line the test draws, following a normal distribution. So the line separating two sides of a bell curve ends up being arbitrary.
And finally, it’s pushed very hard by the Myers-Briggs foundation, and not at all by independent scientific bodies. copying straight from wikipedia:
Most of the research supporting the MBTI’s validity has been produced by the Center for Applications of Psychological Type, an organization run by the Myers–Briggs Foundation, and published in the center’s own journal, the Journal of Psychological Type (JPT),
I risk sounding very “AKSHUALLYY” here, but online tests do a huge harm to the credibility of MBTI, no wonder it gets such a bad rep when the tests are so unreliable and people nevertheless base their entire personalities on it… Originally it’s not supposed to be based on the binary choices of the 4 letters but the “cognitive functions” as defined by Carl Jung, which a lot of people will find to be just as much non-sense but with the right attitude I think they’re a useful tool to learn about ourselves and others.
Humanity cannot and will not change its practices fast enough to avoid running out of resources we keep ourselves dependent on because it’s “profitable.” We are a doomed species and won’t be around for very much longer. We are likely living in the flash of bright before the long dark. I don’t think the world my grandchildren live in will be remotely like the one we have now.
I’m perfectly fine hedging my bets and living life normally, but I think our longevity is an uncomfortable truth most people don’t want to face.

Ah yes, as if anarchism, liberalism, libertarianism or really any other human ideology and methodology centered entirely on egoism don’t engender some strange communal cargo cult behavior. It’s almost as though they too are full of shit?
It is funny to believe in ‘self-determination’ when you can’t even recognize that all the important decisions have already been made for you. It is rich to pretend to fight against the nihilist when you only believe in yourself. So go egoist, live your life as you please, blissfully unaware that you are just as stuck the very herd of individuality that we all find ourselves in.

Timezones are fucking stupid. Everyone should just use UTC or Zulu
Wait am I supposed to upvote this or down vote if I agree?
Yes.
correct. also daylight savings and the 12-hour clock is bullshit. we should at least have Greenwich/UTC as a secondary clock, kinda like how some regions have their own calendar and have the Gregorian calendar as a secondary.
Timezones are stupid and using European as the reference is imperialistic. Every clock should be set to the time calibrate where I live.
As a seafarer who moves through the world, arguing out of timezones is an uphill battle. (Minus the half hour timezone insanity.)
Daylight savings on the other hand, can be dropped like the smelly turd it is.

What we’re currently calling AI isn’t AI but just a language processing system that takes its best guess at a response from it’s database of information they pilfered from the internet like a more sophisticated Google.
It can’t really think for itself and it’s answers can be completely wrong. There’s nothing intelligent about it.
This whole open AI has Artificial General Intelligence but they’re keeping it secret! is like saying Microsoft had Chat GPT 20 years ago with Clippy.
Humans don’t even know what intelligence is, the thing we invented to try to measure who’s got the best brains - we literally don’t even have scientific definition of the word, much less the ability to test it - so we definitely can’t program it. We are a veeeeerry long way from even understanding how thoughts and memories work; and the thing we’re calling “general intelligence” ? We have no fucking idea what that even means; there’s no way a bunch of computer scientists can feed enough Internet to a ML algorithm to “invent” it. (No shade, those peepos are smart - but understanding wtf intelligence is isn’t going to come from them.)
One caveat tho: while I don’t think we’re close to AGI, I do think we’re very close to being able to fake it. Going from Chat GPT to something that we can pretend is actual AI is really just a matter of whether we, as humans, are willing to believe it.

8÷2(2+2) comes out to 16, not 1.
Saw it posted on Instagram or Facebook or somewhere and all of the top comments were saying 1. Any comment saying 16 had tons of comments ironically telling that person to go back to first grade and calling them stupid.

Correct! It’s exactly the same as (2x4).

Ummm, I was agreeing with you??
Anyways, I’m a Maths teacher who has taught this topic many times - what would I know?
And both you and people arguing that it’s 1 would be wrong.
This problem is stated ambiguously and implied multiplication sign between 2 and ( is often interpreted as having priority. This is all matter of convention.
I see what you’re getting at but the issue isn’t really the assumed multiplication symbol and it’s priority. It’s the fact that when there is implicit multiplication present in an algebraic expression, and really best practice for any math above algebra, you should never use the ‘÷’ symbol. You need to represent the division as a numerator and denominator which gets rid of any ambiguity since the problem will explicitly show whether (2+2) is modifying the numerator or denominator. Honestly after 7th grade I can’t say I ever saw a ‘÷’ being used and I guess this is why.
That said, I’ll die on a hill that this is 16.

There is another example where the pemdas is even better covered than a simple parenthetical multiplication, but the answer there is the same: It’s the arbitrary syntax, not the math rules.
You guys are both correct. It’s 16 and the problem is a syntax that implies a wrong order of operations. The syntax isn’t wrong, either, just implicative in your example and seemingly arbitrary in the other example I wish I remembered.
Do you not understand that syntax is its own set of rules?

This is not one of the ambiguous ones, but it’s certainly written to be. Multiplication does indeed have priority under pemdas.
A matter of convention: true
False. Actual rules of Maths
This is not one of the ambiguous ones
There aren’t any ambiguous ones - #MathsIsNeverAmbiguous
Let’s see.
8÷2×(2+2) = 8÷2×4
At this point, you solve it left to right because division and multiplication are on the same level. BODMAS and PEMDAS were created by teachers to make it easier to remember, but ultimately, they are on the same level, meaning you solve it left-to-right, so…
8÷2×4 = 4×4 = 16.
So yes, it does equal 16.
Depends on whether you’re a computer or a mathematician.
2(2+2) is equivalent to 2 x (2+2), but they are not equal. Using parenthesis implicitly groups the 2(2+2) as part of the paretheses function. A computer will convert 2(4) to 2 x 4 and evaluate the expression left to right, but this is not what it written. We learned in elementary school in the 90s that if you had a fancy calculator with parentheses, you could fool it because it didn’t know about implicit association. Your calculator doesn’t know the difference between 2 x (2+2) and 2(2+2), but mathematicians do.
Of course, modern mathematicians work primarily in computers, where the legacy calculator functions have become standard and distinctions like this have become trivial.
It seems you are partly correct. You are correct in saying that this is how it used to be done (but that was 100 years ago, it seems) and you are correct that in modern times, this would be interpreted as I did it, above.

I’m old but I’m not that old.
The author of that article makes the mistake of youth, that because things are different now that the change was sudden and universal. They can find evidence that things were different 100 years ago, but 50 years ago there were zero computers in classrooms, and 30 years ago a graphing calculator was considered advanced technology for an elementary age student. We were taught the old math because that is what our teachers were taught.
Early calculators couldn’t (or didn’t) parse edge cases, so they would get this equation wrong. Somewhere along the way, it was decided that it would be easier to change how the equation was interpreted rather than reprogram every calculator on earth, which is a rational decision I think. But that doesn’t make the old way wrong, anymore than it makes cursive writing the wrong way to shape letters.
it was decided that it would be easier to change how the equation was interpreted
No, it wasn’t. The claim that the rules were changed is a debunked myth.
No, that video is wrong. Not only that, if you check the letter he referenced Lennes’ Letter, you’ll find it doesn’t support his assertion that the rules changed at all! And that’s because they didn’t change. Moral of the story Always check the references.
A computer will convert 2(4) to 2 x 4
Only if that’s what the programmer has programmed it to do, which is unfortunately most programmers. The correct conversion is 2(4)=(2x4).
in the 90s that if you had a fancy calculator with parentheses, you could fool it because it didn’t know about implicit association. Your calculator doesn’t know the difference between 2 x (2+2) and 2(2+2), but mathematicians do
Actually it’s only in the 90’s that some calculators started getting it wrong - prior to that they all gave correct answers.
Under pemdas divisor operators must literally be completed after multiplication. They are not of equal priority unless you restructure the problem to be of multiplication form, which requires making assumptions about the intent of the expression.
Under pemdas divisor operators must literally be completed after multiplication
Not literally. It’s only a mnemonic, not the actual rules.
They are not of equal priority
Yes, they are. Binary operators have equal precedence, and unary operators have equal precedence.
Okay, let me put it in other words: Pemdas and bodmas are bullshit. They are made up to help you memorise the order of operations. Multiplication and division are on the same level, so you do them linearly aka left to right.
Pemdas and bodmas are not bullshit, they are a standard to disambiguate expression communication. They are order of operations. Multiplication and division are not on the same level, they are distinct operations which form the identity when combined with a multiplication.
Similarly, log(x) and e^x are not the same operation, but form identity when composited.
Formulations of division in algebra allow it to be at the same priority as multiplication by restructuring it as multiplication, but that requires formulating the expression a particular way. The ÷ operator however is strictly division. That’s its purpose. It’s not a fantastic operator for common usage because of this.
There are valid orders of operations, such as depmas which I just made up which would make the above expression extremely ambiguous. Completely mathematically valid, order of ops is an established convention, not mathematical fact.
They are order of operations
No, they’re not.
Multiplication and division are not on the same level
Yes, they are.
they are distinct operations which form the identity when combined with a multiplication
In other words, they are the inverse operation of each other - welcome to why they have the same precedence.
order of ops is an established convention, not mathematical fact
It’s a mathematical fact.

There was 3 misinterpretations - see my reply to them.
8÷2×(2+2)
But that’s not the same thing as 8÷2(2+2). 2x(2+2) is 2 Terms, 2(2+2) is 1 Term. 8÷2×(2+2)=16 ((2+2) is in the numerator), 8÷2(2+2)=1 (2(2+2) is in the denominator)

Both of those Youtubes debunked in this thread.
Back in gradeschool I was always taught that in Pemdas, the parenthesis are assumed to be there in 8÷(2×(2+2)) where as 8÷2×(2+2) would be 16, 8÷2(2+2) is the above and equals 1.
Yes, it’s The Distributive Law.
Not quite. It’s true you resolve what’s inside the parentheses first, giving you. 8÷2(4) or 8÷2x4.
Now this is what gets most people. Even though Multiplication technically comes before Division the Acronym PEMDAS, that’s really just to make it sound correct phonetically. Really they have equal priority in the order of operations and the appropriate way to resolve the problem is to work from left to right solving each multiplication or division sign as you encounter them. Giving you 16. Same for addition and subtraction.So basically the true order of operations is:
- Work left to right solving anything inside parentheses
- Work left to right solving any exponentials
- Work left to right solving any multiplication or division
- Work left to right solving any addition or subtraction
Source: Mechanical Engineering degree so an unfortunate amount of my life spent in math and physics classes.
It’s true you resolve what’s inside the parentheses first, giving you. 8÷2(4) or 8÷2x4.
Not “inside parenthesis” (Primary School, when there’s no coefficient), “solve parentheses” (High School, The Distributive Law). Also 8÷2(4)=8÷(2x4) - prematurely removing brackets is how a lot of people end up with the wrong answer (you can’t remove brackets unless there is only 1 term left inside).
Absolutely, its all seen as equal so it has to go left to right However as I said in the beginning the way I was taught atleast, is when you see 2(2+2) and not 2×(2+2) you assume that 2(2+2) actually means (2×(2+2 )) and so must do it together.
Ah sorry just realized what you were saying. I’ve never been taught that. Maybe it’s just a difference in teaching styles, but it shouldn’t be since it can actually change the outcome. The way I was always taught was if you see a number butted up against an expression in parentheses you assume there is a multiplication symbol there.
So you were taught that 2(2+2) == (2(2+2))
I was taught 2(2+2)==2*(2+2)Interesting difference though because again, assuming invisible parentheses can really change up how a problem is done.
Edit: looks like theshatterstone54’s comment assumed a multiplication symbol as well.
if you see a number butted up against an expression in parentheses you assume there is a multiplication symbol there
No, it means it’s a Term (product). If a=2 and b=3, then axb=2x3, but ab=6.
I was taught 2(2+2)==2*(2+2)
2(2+2)==(2*(2+2)). More precisely, The Distributive Law says that 2(2+2)=(2x2+2x2).
No, 2+2 = 🐟 so it would be 8÷2🐟 and since 🐟 is no longer a number it becomes 4🐟. So the answer is 4 fishes.
since 🐟 is no longer a number
It’s still a pronumeral though, equal to 4, so the answer is still 8÷8=1.
Math should be taught with postfix notation and this wouldn’t be an issue. It turns your expression into this.
8 2 ÷ 2 2 + ×It already isn’t an issue if people just follow all the rules of Maths.
Under normal interpretations of pemdas this is simply wrong, but it’s ok. Left to right only applies very last, meaning the divisor operator must literally come after 2(4).
This isn’t really one of the ambiguous ones but it’s fair to consider it unclear.
Pemdas puts division and multiplication on the same level, so 34/22 is 12 not 3. Implicit multiplication is also multiplication. It’s a question of convention, but by default, it’s 16.
Incorrect, pemdas puts multiplication before division.
And “Multiplication” refers literally to multiplication signs, of which there are none in this question.
I always thought pemdas was more like P/E/MD/AS with MD and AS occurring left to right
This is how I was taught, but also people don’t really use the ÷ symbol in algebra beyond like 6th grade
people don’t really use the ÷ symbol in algebra beyond like 6th grade
Yes they do, just pick up a high school Maths textbook (in a country which uses obelus rather than colon).
Implicit multiplication is also multiplication
There’s no such thing as implicit multiplication. The answer is 1.
I don’t know what you’re on about with your distributive law thing. That just states that
a*(b + c) = a*b + a*c, and has literally no relation to notation.And “math is never ambiguous” is a very bold claim, and certainly doesn’t hold for mathematical notation. For some simple exanples, see here: https://math.stackexchange.com/questions/1024280/most-ambiguous-and-inconsistent-phrases-and-notations-in-maths#1024302
That just states that a*(b + c) = ab + ac
No, The Distributive Law states that a(b+c)=(ab+ac), and that you must expand before you simplify.

We learn and teach inferior personal computing practice, and most people don’t realize how much they are missing.
The vast majority of people outside of enthusiast circles have absolutely no idea what a personal computer is, how it works, what is an operating system, what it does, and how it is supposed to be used. Instead of teaching about shells, sessions, environments, file systems, protocols, standards and Unix philosophy (things that actually make our digital world spin) we teach narrow systems of proprietary walled gardens.
This makes powerful personal computing seem mysterious and intimidating to regular people, so they keep opting out of open infrastructures, preferring everything to come pre-made and pre-configured for them by an exploitative corporation. This lack of education is precisely what makes us so vulnerable to tech hype cycles, software and hardware obsolescence, or just plain shitty products that would have no right to exist in a better world.
This blindness and apathy makes our computing more inaccessible and less sustainable, and it makes us crave things that don’t actually deserve our collective attention.
And the most frustrating thing is: proper personal computing is actually not that hard, and it has never been more easy to get into, but no one cares, because getting milked for data is just too convenient for most adults.
Completely agree. Now my hot take for this thread:
If governments some time in the 90s had decided from the start to ban computer hardware from being sold with pre-installed software then we wouldn’t have this problem. If everyone had to install their own operating system from scratch, which like you say isn’t hard if it’s taught, it would have killed the mystery around computing and people would feel ownership over their computers and computing.
How to learn this? The way it’s taught is so people don’t know they don’t know. What are good starting resources?
I am not a professional educator, but in general I think it is worth to start with basic computer literacy: identifying parts of a PC, being able to explain their overall functions, difference between hardware and software, and what kinds of software a computer can run (firmwares, operating systems, user utilities etc.). This would also be a perfect time to develop practical skills, e.g. (assuming you are a normatively-abled person) learning to touch-type and perform basic electronics maintenance, like opening your machine up to clean it and replace old thermal compounds.
After that taking something like “Operating systems fundamentals” on Coursera would be a great way to go on.
It really depends on your goals, resources and personal traits, as well as how much time and energy you can spare, and how do you like to learn. You can sacrifice and old machine, boot Ubuntu and break it a bunch of times. You can learn how to use virtualization and try a new thing every evening. You can get into ricing and redesign your entire OS GUI to your liking. You can get a single-board computer like RaspberryPi and try out home automation.
