cw math, I guess

Good morning.

mornin, this is my mom’s older dog charlie. he’s mellow

good morning

morning, it's launch day for a thing my team built, wish us luck

good morning

good morning

Richard Stallman? Yes,

had a dream last night that I bought a midi controller at a thrift store, good morning

good morning, last night I continued watching Canada’s Worst Driver, descending further into the Andrew Younghusband Cinematic Universe

this is the season where one of the nominees has an acquired brain injury, and they’re treating the subject with remarkable sensitivity. for television, anyway.

wait, does dressing up as a tin of sardines make Andrew a scalie?

good morning, Siri doesn’t know how to pluralize temperature degrees because it’s written by damn Americans and their damn foolish Fahrenheit

good morning to late capitalism, babey

good morning, instead of a weird image, today you get a song: https://open.spotify.com/track/5vRmAKxjZfiGhTwWUijSAV?si=5vTf1R3aQSiky9Lrb_fAxg

good morning

good morning; we put Dave's cat bed on the book case and he loves it

good morning, I recorded a song about capitalism https://soundcloud.com/ash-furrow/capital

good morning, Canada got a new food guide and it includes hydration, so make sure you're hydrated!

it also includes tips like "cook more often", mindful eating, and awareness of food advertising

I feel like that's a cool step forward. It'd be more cool of ol' JT would just reform food advertising.

oh, but for market forces!

here is your government-mandated recipe for healthy kraft dinner: https://www.canada.ca/en/health-canada/services/canada-food-guide/tips-healthy-eating/meal-planning-cooking-healthy-choices/recipes/mac-cheese-with-veggie-twist.html

god damn nanny state, at it again!

good morning, my umbrella broke on my walk to work : \

@ashfurrow I'm having a really big think over this.

@trickster it’s a puzzler 🤔🤔🤔

@ashfurrow I just checked this and it's true. Brackets change everything.

@adz @ashfurrow It does it without the brackets too! But so does Bing and DuckDuckGo.

@ashfurrow technically the minus sign is a multiplication with -1, therefore it could make sense that it has lower precedence than exponentiation.

Wolfram Alfa gives the same result (even for -3^2), and they are math guys.

@ytg @ashfurrow Precedence rules are PEMDAS:
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

So the calculator query shows "-(3 squared)" which is -9.

You have to type "(-3) squared" to get 9.

@cj @ytg it’s really a question of changing language into symbolic math; I think most people would say the answer should be 9, but language is always ambiguous. If I use a calculator and press the buttons “-“, “3”, and “x^2”, the answer is indeed 9.

@ashfurrow @cj @ytg
Not in whatever calculator I appear to have on Ubuntu. pressing '-', '3', and 'x^2' yields -9.

When I use parens around -3, I get 9.

@rcode3 @cj @ytg the iOS calculator app handles this properly, and iirc, my TI-83 did as well.

Again, this is all the ambiguity of language. There's no "correct" answer, but some answers are more correct than others.

@cj @ytg is it a multiplication by -1? I consider “-3” to be its own number unto itself. But again, language :)

@ashfurrow negative numbers don't exist. 😉

@ashfurrow Isn't that the negative of 3^2, not (-3^2)?

@danyeaw that’s correct

@ashfurrow Looks like it’s calculating the square of 3 and then negating it.

@ashfurrow Which, to be fair, is wrong if I remember correct order of operations

@djmoch well, order of operations only matters if there are multiple operations. (-3)^2 only has one operation: the exponent. This highlights the ambiguity of natural language. If a mathematician says the words" negative 3 squared", they mean (-3)^2 because -3 is a number unto itself (and not an operation). There's no purely correct answer, but I'd say that 9 is "more correct" than -9.

@ashfurrow
It's a unary '-' minus, yielding 0-3^2

@erAck “-3” isn’t an operation, it’s a number. And the ambiguity of the natural speech “negative three squared” is highlighted by the difference of “(negative three) squared” vs “negative (three squared)” - I would argue the first is _more_ correct.

@ashfurrow
This gave me a good laugh, thanks Ash!

@ashfurrow
The best thing is when you do this to a 13 year old and they give you a look like "ugh, really? I'm too old for your shit"

@ashfurrow your shipping some sort of CI then?

@tapi @ashfurrow I would argue that the picture gives away too much information on your secret project.

And Dave looks up from YouTube and asks, what kind of containers are you using?

@ashfurrow A transport system for migrants fleeing war torn areas?

@ashfurrow Y U HATING ON COSTA RICA??

@bremner BUT °C MEANS “DEGREES COSTA (RICA)”

@ashfurrow I guess they forgot about “?:”. Silly programmers.

@SuperFloppies aye

@ashfurrow I wonder if the formatting code is converting a number from °F but using the original number for the plural selection.

@ashfurrow
Hahaha ,true

@ashfurrow I keep thinking that one day we're going to spot buildings that are designed to remind us of legos...

@ashfurrow That's cute.

@ashfurrow I think I'll continue with the tried-and-true method of "buying a box of Kraft Dinner from Target" ;o)

(I'm in shape. Round's a shape.)

@ashfurrow Open box, pour into water. Boil until tolerable. Devour orange substance. Return to other tasks.

@ashfurrow but where are the instructions for making it in my instant pot! Trudeau just half assing thing left and right
