New year, new good morning thread!

Good morning! Check out my dad’s table saw.

good morning

good morning to all the very smart engineers over at google

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

medical (~)

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: open.spotify.com/track/5vRmAKx

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

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

@ashfurrow "Nice beaver!"

@ashfurrow has Canadian aura around it

@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
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 Saw this image. Is this really how ships are shipped or is this just a bit of GIMP or Photoshop? 🤔

@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.

@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.
