What is your credit card number and all the information needed to use it?
/c/DSP. Digital signal processing, i.e. how to transform, filter, and live with digital signals (e.g. audio files, image files, video files, sensor measurements, etc.). It involves a lot of math, so unless we get R*ddit-like numbers I don't really know how such a community could keep moving.
Sounds like fun! I'm going to bed soonish but I'm willing to answer questions about multivariable calculus probably when I wake up.
When I took multivariable calculus, the two books that really helped me "get the picture" were Multivariable Calculus with Linear Algebra and Series by Trench and Kolman, and Calculus of Vector Functions by Williamson, Crowell, and Trotter. Both are on LibGen and both are cheap because they're old books. But their real strength lies in the fact that both books start with basic matrix algebra, and the interplay between calculus and linear algebra is stressed throughout, unlike a lot of the books I looked at (and frankly the class I took) which tried to hide the underlying linear algebra.
I'm autistic too and I had to relearn math as an adult. Now I know calculus and advanced mathematics.
I can go find some book recommendations, but when I was first learning I really got a lot out of watching The Organic Chemistry Tutor.
Linear algebra (ex: multiply the matrices A and B), multivariable calculus (example: find ∇F with F=[xy,yz,xz]^T ), or actual "multidimensional analysis" (example: define the norm of [1m,1m/s,1m/s^2 ] in a way that makes sense)? I can help with all three.
Humans are good enough. It's the shareholders who suck here.
It can use ChatGPT I believe, or you could use a local GPT or several other LLM architectures.
GPTs are trained by "trying to fill in the next word", or more simply could be described as a "spicy autocomplete", whereas BERTs try to "fill in the blanks". So it might be worth looking into other LLM architectures if you're not in the market for an autocomplete.
Personally, I'm going to look into this. Also it would furnish a good excuse to learn about Docker and how SearXNG works.
LLMs are not necessarily evil. This project seems to be free and open source, and it allows you to run everything locally. Obviously this doesn't solve everything (e.g., the environmental impact of training, systemic bias learned from datasets, usually the weights themselves are derived from questionably collected datasets), but it seems like it's worth keeping an eye on.
Google using ai, everyone hates it
Because Google has a long history of doing the worst shit imaginable with technology immediately. Google (and other corporations) must be viewed with extra suspicion compared to any other group or individual because they are known to be the worst and most likely people to abuse technology.
Literally if Google does literally anything, it sucks by default and it's going to take a lot more proof to convince me otherwise for a given Google product. Same goes for Meta, Apple, and any other corporations.
I have a "unique" accent of some kind. Basically, I don't sound like I'm from "around here", even though I have lived in the same area for my entire life and so have my parents. Probably because I read a lot more than I actually talk to people.
If that happens then I swear to fucking God I'm done with YouTube forever.
Edit: i.e. if it breaks FreeTube, Invidious, Sponsorblock, etc. (because I'm already done with the main site forever) then I'm out. If the choice is between content vs no ads, I'll take no ads even if it means no content.
simultaneously blame democrats ... for having too much government reach and action on immigration and the border AND THEN turn around and complain that they are too soft on the border and immigrants are just flying through.
I don't think anyone around here thinks that Biden's being "soft" on the border...or that we should even have a border in the first place...
The phrasing "too much government reach and action on immigration" (because they should have none, which neither party offers) and "soft on the border and immigrants are just flying through" (because any maintenance of the border is unacceptable, whether "soft"-looking or not) really shows how silly it is to try and pigeonhole everything into partisan newspeak. Let's say it like it is: borders suck and all of us here (I hope) are going to criticize any party or group that wants to continue hurting people because of them, regardless of who they claim to represent.
it's sooo cool to blame Democrats (and apparently liberals...
I mean yeah it totally is lmao.
Last panel should be the entire US Customary System, which is literally just a rescaling of the SI ("metric" system) units. US Customary is derived directly from SI.
Going to bars. I can't drink with my medications and I don't like going to loud, social places unless there's some other reason to be there.
DSP (digital signal processing) is the field of applied mathematics and engineering dedicated to transforming and manipulating digital signals.
Examples of real digital signals include audio files, image files, video files, and digitized recordings of various physical quantities by computers like the configuration of a robot as it moves in time, measurements of the processes in a factory, the trajectory of a spacecraft — almost anything that can be periodically sampled and take on a finite set of values [1] can be seen as a digital signal.
DSP includes using tools like the Discrete Fourier Transform (DFT), the Z-transform, wavelet analysis, probability, statistics, and linear algebra to do things such as filter a signal (example: audio equalizer), predict future values (example: weather forecasting), data compression (example: JPEGs), system identification (example: fit a model of the earth to predict seismic activity), control (example: make a DC motor to respond to position commands), and stabilization (example: keep plane from "wanting" to smash into the ground). Particularly, it requires a careful consideration of the effect of sampling a signal (example: if done carelessly, you can make the sampled system unstable [read: explode]), as well as an interpolation process of some kind if you plan on using that signal outside your computer (example: you want to hear an audio signal stored on your computer).
I got into DSP because I was an audio engineer and musician [2], and I wanted to design my own audio plugins. IMO I think almost everyone would benefit from some knowledge of DSP, but the math is really intense. Personally, I found out late in life that I have a nearly infinite appetite for math, so it's a good fit for me.
Here's a playlist about DSP if you're interested.
[1] Actually, a lot of basic DSP books don't restrict the signal to be in a finite set because it makes the math easier if the signal could be any real number. However, certain structures that would be exactly equivalent in theory are not equivalent on a real computer because ordinary computer arithmetic is approximate.
[2] I still play music, but not as much as before engineering school.
I can poop on the floor. But I bet you can too.
I'm autistic. This problem shows up for me all over the place, to the point that I typically don't recommend reading anymore except when strictly necessary. However, it is showing up now because I'm working with people on a project (and generally everyone I have worked with at school so far) who will not read, particularly documentation for tools and programs, data sheets, and application notes. How do I get people "up to speed" if they refuse to read the things I send them?
Some concepts are simply too complex or too lengthy for me to explain correctly in a real conversation. It's really the fact that nobody seems to want to read in any field of endeavor suggests that it's something wrong with me and how I perceive things.

It's one of those "self-loathing days" so this track is particularly fitting.
My grandmother wants to install Mahjong onto her phone. I couldn't find any results on the Play Store with no ads or in-app purchases. She doesn't understand technology and could get tricked into purchasing stuff or compromising her data.

I'm fucking tired of explaining to business ghouls that I AM FUCKING DESPERATE. I'M INTERVIEWING WITH YOU BECAUSE I WANT TO SURVIVE. I DON'T GIVE A FUCK ABOUT MY DREAMS OR WHETHER THIS JOB OR YOUR COMPANY LINES UP WITH MY CAREER GOALS. WE ARE HOLY-SHIT PAST THE POINT WHERE I'M ABLE TO BE CHOOSY. ALL YOU FUCKING NEED TO DO IS READ THE FUCKING RESUMÉ THAT'S RIGHT IN FRONT OF YOUR GOD-DAMNED EYES, ASK ABOUT MY QUALIFICATIONS, AND TELL ME WHETHER OR NOT I'M A GOOD FIT.
NO, your company isn't special to me, and it isn't special to ANYONE but you and your business-ghoul friends. Your company is merely the LABEL that will decorate my paycheck and LITERALLY NOTHING ELSE, AND I'M SICK OF PRETENDING OTHERWISE.
And WHY the FUCK are you calling me to literally REPEAT SHIT YOU'RE TOO FUCKING IGNORANT TO READ ON THE GOD-DAMNED FUCKING RESUMÉ?
I've applied for at least 200 engineering jobs (I recounted the ones on job sites; but even that's nowhere near all of them) this year and gotten zero offers. This job search is LITERALLY DRIVING ME INSANE, because I can no longer fucking afford antidepressants and I'm on the verge of blowing up in people's faces all the goddamn fucking time. I CAN'T DO THIS ANYMORE.
> Try [insert nearby industry here]
Funny story: turns out, there are people who studied for degrees in those nearby industries. No I can't land a software developer, data scientist, IT, etc., job, because (1) I've applied for all those several times and not even gotten an interview and (2) my school produces students who actually studied those topics as a major!
So thank you genuinely to the dozens of people who have recommended that, I really do appreciate the help ... but that only works if you're an appealing candidate in general.
> Why are you unhirable?
Bad GPA (~2.8; many firms have hard cutoff > 3 or 3.1), no experience/internships, no support/professional network, recent downward trajectory on transcript, autistic, mentally ill getting more unstable by the day, terrible attitude that's impossible to fully hide, no charisma to accommodate for my deficiencies, no access to a time machine. I KNOW how I got here, but that doesn't mean I have to like it.
At least when I worked in food delivery I managed to make non-trivial money. AT LEAST I WAS HAPPY while being exploited. Now I'm thousands of dollars in debt, literally a hundred pounds heavier, psychologically and emotionally BROKEN, and no closer to getting a real job than I was before.
I was actually going to write a fresh post, but then I realized that a lot hasn't changed since the last time I posted here. Here's the old post if you're interested.
Short version: I cannot find employment at all in my field (electrical engineering). It's not "we're not hiring", it's "we're not hiring you." I need to pay bills. I am physically and emotionally exhausted from being so close to poverty for so long.
What has changed:
-
I have been through about 10 interviews. Furthest I've gotten in one company's hiring process is to 2nd interview. Rather than 30 applications, I have filled out over 150 applications, but I've honestly lost track. No offers. I have exhausted all the entry-level engineering opportunities my college's job board has to offer. I literally have to wait for new jobs to be posted because I applied for everything. The problem is that I don't have experience. My resumé is fine (probably) as it gets me interviews, but I simply do not have engineering experience. I am fully convinced that no engineering firm will hire me in my current state.
-
I ran out of meds about a month ago, so I feel a lot more irritable. My parents have offered to pay for a psych appointment and meds, but like...once. I will take it, but I'm waiting until I know for sure I can get more meds by the time I run out.
-
To my absolute shock, I was accepted to pursue a master's degree at my alma mater, and the Financial Aid department has assured me that I qualify for financial aid. So at least I'm allowed to...go into further debt for further education. Yay.
Now if capitalism [1] were not an issue, I would immediately pounce at the opportunity to do a masters degree. I enjoy learning and if I thought I could choose, I would go into research. However, I gotta pay the rent (even and especially if I live with my parents), I gotta eat, and I gotta pay back the loans. Even if I go with the degree, I have to make money to pay the rent while I'm in school.
My degree is/would be in electrical engineering. I always told myself I'd be able to get a job after all this, I always told myself I picked a "safe" major. But I can't do this anymore. I can't be constantly living on the edge of poverty like this. And the fucking interviewers are starting to ask about the gap in my work history since I fucking graduated. HOW THE HELL AM I SUPPOSED TO GET EXPERIENCE IF YOU STUPID FUCKS WON'T LET ME GET EXPERIENCE?!?!? I wish I never went back to fucking school and I fucking hate my life.
[1] Not looking to proselytize or debate politics, but I'm not sure how else to explain to people what economic impulses force me and most other humans to act against our interests. If it bothers you, replace "capitalism" with whatever you think is responsible for making ordinary people act against their economic interests.
I hope this is welcome here, as it's about autistic burnout. Mild CW for swearing and general negativity.
I finally got my diploma, literally just a couple hours ago.
No I'm not bragging because I'm not fucking proud. It wasn't a fucking accomplishment. I graduated with a 2.8 by the skin of my teeth. My transcript shows a recent downward trend. It took almost double the time; I did two years in four, and I took out loans to live in poverty away from home, just to limp back home to screw up the last semester.
And I fried my brain in the process. I'm not just afraid of getting a new job, but I would be nervous to even go back to the way things used to be. My parents are like "oh you can go back to pizza delivery" but what they don't seem to grasp is that I can't even do that anymore. I've been having trouble planning to do projects and activities, even things I want to do. My body feels like it permanently changed for the worse. I literally gained a hundred pounds. Taking care of hygiene feels is too tiring to finish. My ability to remember things is absolutely devastated.
It's not healthy to be on the brink of disaster for so many years.
So far, I have gotten exactly zero interviews after contacting about thirty employers. (Even the simple task of applying for work feels incomprehensibly complex. I'm good with computers, but it's just so much typing and reading the job descriptions and stuff.) What good is a degree without a job? Congratulations, I know things, but what good is that for me if I starve to death? What good is it if I can't be at peace or even comfortable? How am I supposed to pay off my loans? None of my professors liked me, I made no friends at school, joined no clubs, did no extracurriculars other than some research that I can't explain to a recruiter. I have no experience in the field, not even an internship. I don't have anything to offer an employer [1].
I have already gotten employers bring up the GPA unprompted to reject me for the position. Most engineering firms aren't interested in students with a GPA < 3. I've applied for all sorts of other jobs, but I'm competing with people who actually studied in that field. I have no projects in a state suitable to present on a resumé, and every recent attempt to start a project has gone almost nowhere.
And frankly, I'm not particularly friendly or sociable. I am ice cold, even when I'm trying to be warm. Even when I'm fully prepared for a social situation, I am still autistic, and people will inevitably find me awkward in a bad way. I'm not open about my political views IRL [2], but it's very difficult to hide my disdain for capitalism and imperialism from people who think they benefit from them [3].
I would be literally thrilled to do a master's degree in my field, as I read graduate-level material in my spare time, the rare times I have any energy. However, how could I pay for it? How could I convince an employer to pay for it with my transcript and recent downward trajectory? And if I get accepted, how do I even begin to manage that time? I could barely handle the workload of a bachelor's degree, and I can barely even handle the workload of looking for a job or even cleaning my body.
I'm sick and tired of being sick and tired. I just want to be able to do things like I used to be able to do. I just want to go back to a time when it actually felt good to achieve my goals. If y'all have any similar experiences, advice, or just want to dunk on my situation, I'd really like to hear it.
[1] I'm not seriously shedding a tear over these "poor employers" and how I can't provide value to them. I don't give a fuck about them, fractally so. However, the "value I offer to the company" is the lens through which they view my employability, which in turn determines the level of comfort my paycheck yields me or if I get that comfort at all.
[2] I'm not a great rhetorician. If I argue for my views, I will probably make my case look worse. It takes a lot of energy to talk, so my arguments are usually really sloppy when talking in person. For this reason, I'm very careful to look like a "normie." E.g., you would not peg me for an anarchist if you met me on the street.
[3] I don't apply for defense contractors, police contractors, or prisons for ethical reasons, mostly ACAB-related. Engineers usually have no conscience of the world outside their field; e.g., a job is a job regardless of how your product gets used. This alone kills so many otherwise excellent job opportunities, and it alienated me from my peers. Turns out that the fash pays well for your integrity.
I want to go into research, like the biomedical research I did at school, but I don't think I have the grades for that. I became an engineer to do good things with math and science. I'm not giving up on that, but I'm tempering my expectations for sure.

No, but I'm not at risk of self-harm. I'm just waiting on the good times now.
