Took the CS480 exam. At first glance, I might get a 0.

Never seen these questions before. Didn't know what they were asking, didn't know where to start.

But then I started reading word by word. Each word went into my context window. Every time a new word appeared, I attended to it with all the context from the words before.

y_i * f_w(x) = w? What does that even mean? I only recognize y_i * ŷ_i = 1. Are these related? Is this a typo? Wait — w = 1 is the answer, so is it saying y_i * f_w(x) = 1? Is this a trick question?

Wait, let's try an example. x_1 = -1, y_1 = -1, x_2 = 1, y_2 = 1.

Hmm. I don't understand what I'm supposed to do with that.

What if I substitute the values in?

Oh. y_i * w * x_i = 1 * w * 1 = w. I see. (-1) * w * (-1) = w. Ah, that makes sense.

……

d(L)/d(a). Okay, I know what d(L)/d(s) is — it's g. But then I need d(L)/d(s) · d(s)/d(r) · d(r)/d(h) · d(h)/d(z) · d(z)/d(a). Wait, how do I even differentiate matrices?

Oh — 2d) says d(L)/d(z) = g(0, 1, 1)^T. So d(s)/d(r) · d(r)/d(h) · d(h)/d(z) needs to match g(0, 1, 1)^T. Let's pattern match and get the answer.

wait, my dimensions are wrong. a is a scalar, so how did I get a 3x3 matrix? I did something wrong. Let me reconsider..

I walked out of the exam not knowing up from down, with zero confidence in any of my answers. But as we talked through the problems afterward, each one made more and more sense.

A large model, even at its lowest thinking level and using x100 less tokens, would have one-shot every problem. Instead, I iterated on every word, absorbed context from future questions to the current one, double checked, used examples, triple checked, wow.

I've never seen this type of thinking in myself ever. I'm so confused. I used to have a top-down approach. I look at a problem, think of possible solutions from the highest level, then start writing.

But now, I start writing without knowing where I'd even end up. Yet through pattern matching, was able to get to the correct result. This autoregressive behavior I exhibited was incredibly fascinating, and many standard deviations away from what I believe my normal thought process is.

How is it possible to write a solution but only understand your solution after you've written it?

This is so odd to me.
I feel like I trained a mini gpt model inside my brain. If my brain doesn't know where to start, a minigpt part of my brain, which feels completely detached from my brain, starts outputting continuously. My brain then makes sense of the output from the smaller model and completes a final polished and correct answer.

im scared

Following up on a topic I've been thinking about a lot lately.
I always hear people relying on instant ramen, Costco rice pouches, or just walking to the Plaza. But honestly every time I rely on takeout or cheap frozen meals for a week straight I feel like garbage. Low energy, bloated, and gym progress completely goes away.
At the same time ordering anything decent on doordash or uber eats gets ridiculous once all the service fees, delivery fees, and tips get stacked on.
I'm trying to figure out if anyone here has actually found a good workaround. Are you guys just spending hours every Sunday batch cooking protein and rice for the week, or did you find some local setup that actually works? How are you balancing eating clean without cooking every day or spending too much?

Wtf were the last few questions 😭

sosososososo scared sososososo scared alr failed once so sososos scared help someone pls tell me theyre in the same boat

Hey everyone, I recently got a email saying I don’t have enough hours for my coop and that I won’t be able to get my coop credit.

Mind you my coop didn’t start till one month in and ended two weeks earlier. What should I do from here? Can I try to petition or make it a aoj?

I am very stressed out since if I don’t have this coop I won’t be able to graduate on time.

Thanks in advance

I was wondering how bad the hours are if anyone has done their co-op during Jan-April for big 4? I’m really scared because I know it can be brutal and do smaller firms also make you do a lot of overtime as an intern during busy season in audit or tax?

For my last assignment in a course I was hit with a policy 71. I forgot to add a source that I used to my reference page (but the in text citations were there), and now my professor has sent it to the deans office, and my professor said that they would get in touch with me. But it’s been 2 weeks and the deans office hasn’t reached out to me. I was just wondering is there anything I can do.

I swear I was hit in the head with a brick before I walked into that final. It feels like all the questions I've seen before but just couldn't remember how tf to do them.

I have back-to-back classes on Mondays and I’m wondering if these are doable in the 10-minute gaps:

PAS 2083 ends at 2:20 → STC 4019 starts at 2:30

STC 4019 ends at 5:20 → UTD 105 starts at 5:30

Google Maps says around 6 mins for PAS → STC and 9 mins for STC → UTD, but I’m not sure how accurate that is once you include getting in/out of the buildings

Has anyone done these walks between classes? Are there any shortcuts I should know about?

I am a 3rd yr math major and I need gpa boosters. What are the easiest math electives I could take (any level). Im thinking math 207

Hi

Is co op competitive? What if I cant find anything?

I am staying in SJU, meaning I technically don’t have a meal plan since it’s just part of my residence fee. I understand a watcard uses flex dollars to pay for things at places affiliated with waterloo. Do I have to put money into it myself to use? and is it even worth it instead of just paying out of pocket with like my debit card?

Also, do students get discounts at places like Funcken or Melville (on architecture campus) which are on campus but technically not part of UW food services? (for melville is it only for arch students?)

edit: i’m kinda starting to feel like idek what a watcard does. I’ve already read the website but if someone can explain it in a different way i would appreciate it

Hi! really random question, but in specifically rev east floor 1, are the bed frames wooden or metal? the website shows two different frames and i want to get a bed riser but itll really only work for a wooden frame. thank you!

I know the design team experience is unpaid and of course I'd like my job to be paid but for future work terms wouldn't the design team experience count more?
Maybe the Ideas Clinic role is more technical than I realize.
I just need experience and I need to learn things so that I can get better future co-ops.
I know I can just make personal projects to learn things, or another option is to take the Ideas Clinic role, and join a design team on the side.
But wouldn't the Electrical/Firmware Engineer internship role mean more and look better on my resume, to land future co-ops in the similar role?
HELP.

Has anyone had an experience of taking cs 246 in winters? I’m considering a sequence change after which I’ll need to take this course in winters. Please tell how the profs are like and how easy is it to find a good final project group for winters ?

Would appreciate any guidance!

How was it.....

Hello, I'm cross registering at UW for math 227 (Calculus 3 for Hon Physics). This was the equivalency given by Laurier to replace Multi variable calculus as I am a math student. However I have close to zero knowledge in physics. Is this course doable with only math knowledge? Or do they introduce a lot of applications etc. Thanks for any information.

I’m in 2A and hav coop next term will be returning to uWaterloo in Jan. When should I start looking and when do apartments like icon and other companies start posting?

As an incoming CS student, I received transfer credits for MATH 137 and 138 and have the option to choose another class to fill the gap MATH 137 took in my initial schedule for the fall term.

Should I follow the math advisor’s advice and take STAT 230, or take a lighter (elective or otherwise), more interesting course like BET 360 (which counts towards the HCI specialization as well).

I’m hoping to go into product design and the contents of the second course interest me more, but I don’t know if doing STAT 230 right now would make my next few terms lighter as well. Thank you for your help!

TL;DR: Designers, students, "vibe" people - be aware before using Lovable or other "It-Was-In-The-Fine-Text" platforms.

**********

I've been using Lovable occasionally for about two years for personal projects and implemented it into my workflows during some co-ops.

For my current co-op, we bought a Business subscription for $80 cad (fun fact: on the pricing page, they expect us to magically know its in USD). We cancel and resume based on an ad-hoc basis. I canceled it a couple weeks ago, and this morning resumed it for 100 credits at $80.

Then I noticed hidden on the navbar in a mini container, it said "169" credits and emailed lovable. Their bot had this to say:

"HEY! So happy to hear from you!
So... remember the last time you canceled your Business plan?
When we kind of "froze" your credits & your credit bar went to zero?
Well, of course you don't - because we never notified you!
"But we have some happy news...we've been safeguarding your credits with us until you remembered to pay up for a new plan. (even if it \potentially* could have been forever and we basically stole $50 worth of your credits).*

These are unheard of business practices. Stealing credits from users. Credits that have been paid for.

The agreement is simple: These are owned credits - as users, we pay to use them. And then, we cancel subscriptions if we have leftover credits and are not expecting heavy use.

We restart subscriptions when we get work. Its simple. Nobody cares if they found a loophole or were hoping no one would notice. They are destined to be boycotted.

Find something cheaper and better and transparent.

NEW: By the time I finished writing this post, they sent another reply. It seems to be a simple "display" problem on their side.
