A friend of mine was complaining about a problem they were having with their statistics class and I offered to help. They had copied and pasted the example code from their lecture and changed some variable names, but after a while we figured out that the csv file their code was using for data storage had a variable whose name had parentheses in it, so R was trying to interpret it as a function. Anyway the punchline is their TA had designed a coding assignment without making sure they could solve it.

Jesus

I spent almost two days debugging and failing to locally reproduce a bug in some CSV getting exported.

When I finally got the prod db dump, it turns out that what looked like a completely different error is in fact and off-by-one shift in some rows, which is because some client inputs contained semicolons, probably for the first time in years. And not sanitizing properly is not even our fault, the relevant code is between 8 and 10 years old, wayyy before we were maintainers.

Today's lesson is: when the client emails you about an error, don't believe their interpretation of what happened.

“Dogs don’t know what they look like. Dogs don’t even know what size they are. No doubt it’s our fault, for breeding them into such weird shapes and sizes. My brother’s dachshund, standing tall at eight inches, would attack a Great Dane in the full conviction that she could tear it apart. When a little dog is assaulting its ankles the big dog often stands there looking confused — “Should I eat it? Will it eat me? I am bigger than it, aren’t I?” But then the Great Dane will come and try to sit in your lap and mash you flat, under the impression that it is a Peke-a-poo… Cats know exactly where they begin and end. When they walk slowly out the door that you are holding open for them, and pause, leaving their tail just an inch or two inside the door, they know it. They know you have to keep holding the door open. That is why their tail is there. It is a cat’s way of maintaining a relationship. Housecats know that they are small, and that it matters. When a cat meets a threatening dog and can’t make either a horizontal or a vertical escape, it’ll suddenly triple its size, inflating itself into a sort of weird fur blowfish, and it may work, because the dog gets confused again — “I thought that was a cat. Aren’t I bigger than cats? Will it eat me?” … A lot of us humans are like dogs: we really don’t know what size we are, how we’re shaped, what we look like. The most extreme example of this ignorance must be the people who design the seats on airplanes. At the other extreme, the people who have the most accurate, vivid sense of their own appearance may be dancers. What dancers look like is, after all, what they do.”

friendly reminder that you can (hopefully) choose at least some of the things that you allow in your life and “because I really don’t want to latch onto that as a special interest/hyperfixation” is a valid reason to not want something in your life.

Approaching the R^infinity question from a vector space PoV, the unit sphere in l_2 with the standard inner product structure is not compact; just surround each “standard basis vector” (ie (1,0,0,…), (0,1,0,0,…) etc. ) with an open ball of radius sqrt(2) / 2. Since the l_2 norm is nice, none of those open balls contains more than one of the “standard basis vactors,” so that is an open cover of an infinite sphere with no finite subcover.

Of course, l_2 is a complete metric space, so if the l_2 topology can be reconciled with R^infinity in a natural way (I dunno about that part, but I wouldn’t be shocked) the R^infinity sphere in *that* topology has a non-compact closed subset, and is thus not compact. (The open cover with no finite subcover being that one we found for the l_2 sphere together with the (necessarily open) complement of the l_2 sphere.

Thank you for adding to my infinity post, and for doing it kindly! My mutual asked me for a fun fact about infinity, so I do the same to you!

One of my favourite things involving infinity is the construction of some interesting topological spaces!

You can construct the Long Line using the first uncountable cardinal, which is an example of a sequentially compact space that isn't compact!

Sometimes it's also possible to make "infinite dimensional" versions of some common topological spaces! This can be done if there is an inductive way of defining those spaces. For example, we can construct Sⁿ by gluing two copies of Dⁿ to Sⁿ along their boundaries. For S² this is exactly the construction of taking the equator (S¹) and gluing each hemisphere to the equator. Because this is inductive, we can define S^∞ to be the space we get at "the end" of the process. The formal way of doing this is with a categorical limit!

One fun fact about S^∞ is that it is contractible, that is we can deform it into a point (formally, S^∞ is homotopy equivalent to the one point space). But none of the finite spheres are!

I keep hearing this; is there somewhere I should look for a proof?

“How was your day?”

“The most up-to-date place to see my pronouns is on my tumblr. The usual username.”

the best part is the easy access to humor. The worst part is the time sink

Emotional intimacy. I have a hard time believing that I can be anything other than an imposition.

not since I was a child and dreamed of an orange that could change how big you are

I broke my arm on my 9th birthday because I couldn’t wait in line.

yeah, but my emotions are confusing to everyone else

emotional proximity. I don’t care if we’re worlds apart, I want to know how your day has been, how you’re feeling, and I want to share the same with you

A universal statement is only false if a counterexample exists. Meaningless things can still be true, and if something only exists in your head, nobody can talk you you’re wrong.

romance

I’d like to be understood. I don’t want to change who I am, but I’d like the world to shift so that I’m not misunderstood when I enjoy the natural presentation of my emotions

friendship, math, dancing

nope

sleeping at the end of a long one

waking up at the end of a long one

not anymore

we don’t talk as much as we should, sometimes I turn around when I’m missing them and trying to sleep, and they forged a lot of my quirks

they are the only person who’s ever given my a shirt unprompted, that shirt went in the garbage without me ever wearing it, and if I did ever put it on, I think I would be a very different person

i know several facts about the number 6

winter. I love the cold

blue. I couldn’t say why

the only one still active is “Nah”, which requires some elaboration

do the phone numbers of queer people I meet count?

sing

social dancing

messy

social dancing, math, spending time with strangers

moving furniture

yes, until I’m given reason not to

I have an online hobby that none of my irls knows about. But that’s pretty much my only wall

The summer camp I worked at in 2021 falsified health and safety records pertaining to the operating temperature of a broken (ie. unable to heat water) mechanical dishwasher

questions I think would be fun to be asked

what are 3 things you’d say shaped you into who you are?

what’s some good advice you want to share?

what are you doing right now?

what’s something you’ve always wanted to do but maybe been to scared to do?

what do you think of when you hear the word “home”?

if you could change one thing about yourself, what would it be?

name 3 things that make you happy

do you believe in ghosts and/or aliens?

favourite thing about the day?

what’s one thing that never fails to make you happy/happier?

are you messy or organised?

how many tabs do you have open right now?

any hobbies?

This movie will never stop haunting me. I saw the director’s cut when I was fifteen and haven’t been precisely the same since. I’m _not_ recommending it for minors (quite the opposite), but it’s not an unpleasant haunting.

Violet & Corky 🎀💋

Ngl I think about them everyday, this movie honestly changed my life and is honestly the best lesbian movie I’ve ever watched next to but I’m a cheerleader. Violet and corkys relationship is just so exciting to watch on screen , felt like I was holding my breath everytime they kissed 😫. Also Gina Gershon in a butch roll changed my brain chemistry forever I need her BAD.

honestly people are way more ignorant about the welfare of the animals than they think they are

animal rights activists are even worse regarding that, because instead of actually learning about what an animal needs and how it behaves they rely solely on how they *think* animals feel and need

and it's the reason why the public views feeding and interacting with wild animals as "being good and kindhearted :) " and keeping animals in zoos as "poor animals suffering in cramped cages >:( "

and it kills animals

also can we stop with the whole “[my way of being trans] is the greatest threat to the patriarchy” thing?

This might be a hot take, but I know a couple of transfems who have seized onto that as a way to feel special about their gender. But when trans people start putting together a hierarchy of subversion, it undermines the whole point of solidarity. the queer community as a whole is a threat to the patriarchy, emphasizing further subdivisions exist only cause strife.

#except volume I stand with the quiet gays

No group of trans people has inherent power/privilege over another group of trans people.

Trans men are not your oppressors.

Trans women are not your oppressors.

Nonbinary people, regardless of AGAB, are not your oppressors.

It is important to interrogate your own biases towards your fellow trans people.

Oftentimes, a decent place to start would be to make friends with Other trans people. You'll probably find that you have much more in common with them then you realize.

As a car mechanic, I can safely say, I don't understand the gay agenda. 

I do however, understand the trans mission.
