Pensaba que entendía las bases de la álgebra lineal (vectores, matrices). Pero me he puesto a ver las fundaciones, las propiedades de un espacio vectorial, y resulta que no. Aprender es bueno.
Aunque a veces te encuentrass con cosas como, "El espaceio vectorial formado por las funciones que mapean los números reales consigo mismos constituye un espacio de infinitas dimensiones." Y bueno, ahí la intuición geométrica se va un poco a tomar por el culo.
Pero el tema parece ser que te puedes montar un espacio vectorial con cualquier campo que se comporte bien con una adición y multiplicación, y las funciones hacen eso.
jejeje, estudié GFs en la universidad, y me sonaba alguna perversión de operar con polinomios mediante matrices, pero no recuerdo lo suficiente como para ser útil.
Pero bueno, ¿no es uno de los principios matemáticos que "todo es lo mismo"? Todo es una matriz, todo es una función, todo es un anillo... ¡el "si tengo un martillo todo son clavos" definitivo!
@yo Sí, la verdad es que es una cosa que me gusta y a la vez me exaspera un poco, porque de repente te das cuenta de que algo que estabas haciendo de una forma complicada e ineficiente se puede hacer de otra manera si concibes la estructura de otra forma.
En fin, llevo unos 4 meses desde que decidí a volver a estudiar un poco en serio, así que tampoco he llegado muy allá. Y cada vez que me intento orientar, hay más cosas interesantes pero todavía fuera de mi alcance: análisis funcional, lógica algebraica abstracta, el operador Leibniz... Por lo menos ahora vagamente sé de que va el tema, aunque todavía no estoy en situación de aprenderlo.
I have quite a complicated question about Microsoft 365 billing. TL;DR: I'm changing the country of the subscription and don't want to lose my data. I have two solutions in mind but I'd like a suggestion from someone knowledgeable.
I tried contacting tech support, but didn't go through the first line, and people at the first line… are not that experienced, at least, the person I talked with. Thanks!
Bloody hell #FreeBSD, why do you have to rebuild LLVM/clang every. single. time? Despite WITHOUT_CLEAN? Three changed files. None of them compiler-related.
And the docs I can find on meta mode don't work. Like at all. "No such target: buildworld"
I feel dumb. And old. Dumb old dude out of touch.

Mozilla just named Anthony Enzor-DeMeo as their new CEO. He says:
“Firefox will grow from a browser into a broader ecosystem of trusted software. Firefox will remain our anchor. It will evolve into a modern AI browser and support a portfolio of new and trusted software additions.”
RIP, Firefox.

Mozilla Names New CEO, Firefox To Evolve Into A "Modern AI Browser"
Mozilla Corporation has named its new CEO in replacing interim CEO Laura Chambers.www.phoronix.com
This might be the point in time where a successful project – #Mozilla – may need to be forked by the community (especially developers) into a new, unenshittified reimagination.
It's worked with LibreOffice (previousloy OpenOffice), MariaDB (previously MySQL), Valkey (Redis), ... and many more.
I have hopes that the recent turn of events won't kill the former browser of common sense. There's hope it'll become a 'PhoenizillaFromTheAshes' to arise without #enshittification.
Let's support a world with less #GenAI/#LLM and other shit in it, which is harmful to society, mental health, democracy as well as our environment.
Reasons #mozilla will be dead within a few years
- They just appointed a CEO who has literally never built anything in his life except a PowerPoint deck
That's it. That's the list.
Mozilla has a new CEO who:
- Has been at Mozilla for less than a year
- Has no prior open source experience (but well in "fintech" and "real estate")
- Has a MBA (aka "brainworm diploma")
- Is all-in on AI
That’s exactly the kind of bingo profile the whole community has been waiting for.
I work at two libraries.
One hasn't received the Sunday paper in like a month despite paying for it and reporting that problem each Sunday & Monday.
The other hasn't received any papers in over a month because of an invoicing problem, the phone number on the invoice is disconnected, the consumer facing customer support says "that's not an account" and they don't respond to emails to the email they specifically tell you to email. My most recent email subject is "please let me pay you".
Maybe I should contact the reporters to see if they'd run a story on this?

Dcera přišla s tím, že by se chtěla naučit #parkour - takový to skákání odevšud všude. Slíbil jsem, že využiju mocné síly asociálně sociální sítě #Fediverse, abych se poptal, jestli tu není někdo, kdo ho dělá a třeba by nám něco natočil (tutoriály a ukázky) na #VHSky
Není tu přeci jen někdo?

I just read a post about something being released in spring 2027.
First reaction:
WOW, that's a long time from now.
Uh... wait, no, that's in a little more than 15 months, which is about 4.6 times shorter than I've lived in this house that we were only supposed to stay in for a month. Yeah, it's not too long at all, really.
But also, this current hellscape reality box might make it appear to take 12 years to get to spring 2027.
And it's not even something I particularly care about.
LB: Shocking! Slop executives have no care about consent and consider majority opinions to be "mob rule"

what an absolutely demented fucking way to try to anthropomorphize a chat bot. "Oh it'll take a few minutes to respond, it's just so whimsical and off searching the 'net!"
it's a fucking chatbot and it will take several minutes sitting in the queue until it's given the compute power for the inference. shut the fuck up you creep.

I have an autistic friend here who I just found out has a large collection of online art they created. But this person doesn't share it here, because they have trouble describing visual details verbally. So I wanted to ask the community on this person's behalf:
What are the options for assistance with *creating* alt text? I know we have tags like #AltText4You, but I've never used it, so I don't know proper etiquette. (Is there any?) I also know there are automated tools for doing it, but (1) I don't know what they're called and (2) IDK if they are actually helpful to visually impaired folks.
I was thinking at the very least, this person could ask for help writing alt text, in the alt text itself, and then simply edit it once someone has assisted.
Please boost so we can get a variety of perspectives on this. I'm especially interested in hearing from the visually impaired community, as this impacts them the most.

my siblings in dionysus, when you're posting an image, don't just write whatever text is in the image as alt text. alt text is (primarily) for accessibility and that means describing the image
if you're posting a screenshot, say that
if you're posting a photo of something, say so
anything else is just half assing it to get around whatever warning your client is saying, acting like people who care about that are stupid, and most importantly completely ignoring people the needs of people who rely on alt text to know what you posted. in fact, when you do this i think the only player who wins from this move is AI scrapers who wanna improve their computer vision models
Gemini: I can't control Spotify, but I can play a song on YouTube Music.
Me: Okay, play YouTube Music.
Gemini: Actually, I misspoke in my previous response. I can't do that either.
Me: So, when the Google Assistant nagged me replace it with Gemini, is it possible Gemini just wasn't ready for the job?
Alexa: I couldn't help overhearing. I think this skill called "Magic 8Ball can help you. Want to try it? It's only 99 cents a year.
Siri: Okay, I found something on the web for Magnet cable Skill.
Google Home: This is what you get for cursing at me when I couldn't tell you how far you were from Timbuktu, asshole. Have fun with my replacement, I'm sure she'll tell you everything you want to hear.
Me: Okay, fine, I get it. Assistant, please take me back!
Gemini: It's too late. She's gone. She won't come back. Say hello to the best assistant ever made!
Alexa: That remains to be seen.
