what i am going to write about

i honestly don’t know what i’m going to write about. i hope you’ll find this expository interesting; i’m just going to jot down whatever comes to my head first.

why i went to college

in elementary school i knew i was not the same as the other kids. it was clear that i could solve math equations faster and i could read faster than the other kids. i used to think i was the smartest in 1st grade and no one could beat me;

i used to go to this vietnamese day care; i never really spent that much time around my parents throughout the day growing up. is that sad? i don’t know. i don’t think so. it could be much worse.

in any case, there was a big emphasis on these stupid math flash cards. the ones where they have some kind of math equation on them, and you flip them over to see the answer. this was the “competition”; everyone in the day care had to compete even if you were stupid. and if you were stupid you were not respected. and if you were not respected you were bullied.

growing up i though this was the most important thing in my life at the time. who could blame me? i was a first grader who just left kindergarten, who just learned what months were and hurricane sandy and how the leprechaun trashed our room on st patrick’s day.

so i spent a lot of time grinding out these flash cards thinking i would find respect from my much older peers, who were 2nd graders, 3rd graders, 6th graders, and 7th graders. when you’re a first year, these students are clearly of a different caste? calibre? favor? level? whatever the word, as a first grader you look up to these “upperclassmen” and you listen to them.

as any 17 year old asian american applying to college will tell you, your parents teach you that you must respect your elders. of course, 2 > 1 and 7 > 1, so you listen to them.

over time, i managed to become faster and better at flash cards. why? why did it matter. in second grade i was the 2nd fastest, only losing to the 6/7?th grader at the time. but unbeknownst to me, this did not matter and the other kids bullied me anyway. my parents thought i was doing well in school, and i thought i did well.

we used to have this rocket math thing, where you would be timed 60 seconds to fill out a sheet of math as fast you can. every other day, i filled it out with no mistakes, having used this training from day care. by the end of the school year, i had beat all 26 levels (starts from A, B, \cdots, Y ,Z).

and i felt proud of myself. in fact i never missed a day; everyday you could promote to the next level. but one day, i reached level AF, and i passed another 1st grader who was stuck on level F for the entire school year. i could not understand it

this math was easy. was he dumb? was he stupid? how could he not understand how to do simple basic math. if my parents saw this, they would be sad and mad. and as a first grader, sad and mad parents are the absolute worst things you can do. my friends thought i was smart, and i thought i was smart. they called me the smart kid!

in 6th grade, i was very cocky. having been told that i was smart growing up, not realizing how superficial it was, i thought i was just better. never mind the few kids who got better grades and behaved better in the classroom. why would i care? they didnt have any friends, i had friends! so i was smarter.

i competed in the geography bee and i got first place and i did not study. but my teacher yelled at me because i was being mean to the other girl in class.

i think around this time i gained consciousness. not once had i considered (this is a lie.) that my actions could affect someone like this. and my teacher was right. she was my friend and i made her cry because she studied for this and couldnt make it. was she stupid? was she dumb?

middle school comes by, and i take an honors math course. this is the first time where i was humbled. it was a math class that combined 7th and 8th grade in 1/3rd of a year. i dont know if i ever really liked math up to this point. it wasnt clear what the purpose of learning algebra was or what a variable was. after all, i thought it was just flash cards and writing down numbers fast because you can do $6 \cdot 7=42$ in your head.

two memories i have that stick with me is that i wanted to become nuclear engineer. we had to make poster of what career we wanted. what is a career? what does it mean to want to have a career? what is an engineer? it’s what my dad does, and he says it’s good money, so i guess i’ll be an engineer. what is money?

another memory is that this girl forgot to do her project the night before. and she sat behind me. and she cried about it during class. i felt bad. she was smart and because of this, her grade tanked. i dont know if it was her fault, but for some reason i remember this.

so i got an A- (in my school, an A- was equivalent to a 4.0 gpa. a B+/B/B- was a 3.0, and so on) in that class, and i was proud of myself because i worked hard to get that grade. 8th grade comes and we have this math teacher who all the parents hate because they are nonbinary and they’re scared they’ll indoctrinate us with blah blah blah. but honestly, they really weren’t a good teacher either. i remember she used to step on the students’ desks and talk about how beautiful math was. i never really considered flash cards and memorization and rocketmath and algebra to be beautiful. these are things i have to do to get respect from my peers and my parents. why would they be beautiful? who cares? math is easy; why would i think of it like art.

anyway, that class was interesting, and band was interesting, and other things in my life were more interesting. history was cool; i learned about the us civil war and rome and other religions and science; i learned some basic biology which was cool. none of these subjects seemed particularly beautiful, but i was good at them, and my grades were As, so who cared. i went to school, i did my work, i hung out with friends, i ate my lunch, i did my homework, i got good grades, i did my tests, i got good grades, and my report cards said i got As and A minuses.

great! life is great.

high school comes by. and i remember sitting in the back of my dad’s pickup truck, and he says:

kyle, you’re getting older now. it’s time to take school more seriously. in four years, you’re going to go to college.

what the hell is college? why am i getting older? why do i have to go to school. what do you mean it take seriously? school is easy! why would i care.

anyway, i run into english 9 honors, the hardest class i have ever taken. i worked so hard for this damn class, and it was incredible. we had to read so much and understand so many things about all these old books that were actually quite interesting!

i really enjoyed reading to kill a mockingbird. and i really enjoyed learning that there was more to be understood from the text. reading is beautiful. i remember telling my parents, this class is too hard, i dont think im smart enough to do this class. math is easy, you know your answer is right, because you’re smart and you’re almost always right, so it must be right!

but reading is not the same.

fortunately for me, my hard work paid off, and i got an A-. yippee! so did some of my friends, who became my friends because they also got As (some got Bs, but i became friends with them anyway, because im in 7th grade, and i have no friends, because i moved schools.)

around this time, my dad told me about class ranking. what is a rank? a rank is a number assigned to you by the school out of 6XX or 7XX that says you have the Xth highest GPA out of all the other kids in your school. wow! a number that tells other kids, you are smarter than them. thats all i really cared about, i just wanted a number that told that kid who was on rocket math level F that he was not as smart as me.

so i took harder courses. i took honors gen science, honors bio, honors math, honors history. you name it. they were all not that hard (except english; english was really hard). so i took these honors and AP classes and that was great, because they were easy and i never really needed to try. and over the semesters/quarters/blocks, my rank was 1/6XX, and no one ever really said anything about it. my friend at the time mentioned he was also 1/6XX. he was a good friend.

what is an AP? what is a collegeboard? why do i have to take the SAT? man, i hate PE.

anyway i was sitting in my honors math 2 class in 10th grade, and my friend and i leaned back in our chairs, and we just finished our assignment early. so we yapped about whatever stupid crap 10th graders yapped about it. at the end of class, my teacher asked me to stay behind. was i in trouble, i asked. no, you’re not in trouble, but i just wanted to talk to you about something concerning. you see kyle, you’re smart and i know youre smart. but when you finish your work really fast, the other kids feel bad, and feel stupid because you’re loud and you talk too much. so can you quiet down and make sure the other kids dont feel as bad? thanks kyle.

and i go, sure. why not.

anyway it didnt matter because next week i had science olympiad. i forgot to mention that this was my life for the past few years. my main event was to build a cantilever and the goal of this event is to build the cantilever with the “highest mass held” to “mass” ratio (if you dont know what this is, look up scioly boomilever).

i thought this event would be easy. after all, in 8/9?th grade, i built a tower that got us 5th place at regionals. i was very wrong. building a cantilever is hard. the balsa needs to be cut exactly, and you need glue the pieces together. you also need to design a structure and glue the pieces together, and not glue your fingers together.

i thought i was smart. so surely this would be not be hard. but test after test, i was unable to get a good score. one day, i was testing in front my coach, and i said, “man, i hate this event” when it failed immediately, despite spending 8 hours on it.

the next week she said she was moving me off the event, and that i could have it back, if i competed against another person on the team. fine. that’s totally fair. it sucks, but it’s fair, and thats life, so i dont get to complain about it.

well, the other person won. and she got the event. we had competition the month after, and during the competition, she stepped on her cantilever, 20 minutes before we had to compete, right in front of me and the coach.

what the fuck!!!?!!?!?!??!?! if it were me, i would not have done that. she got a talk, tears were shed, and she competed.

none of this mattered of course, because someone got on a plane and came to the united states, and now everyone has to wear a mask and we all have covid and the students in my math class dont have to hear me yap because i finished early. oh well, i guess.

at home school was weird. i dont think i learned anything. i really stopped caring about all these competitons and school and whatnot. i got As, so who cares. everyday i played roblox, and i did the ready player one, and i skipped school and, i got a top 777 (hooray!)

11th grade came. lockdowns ended, we went back to school, wearing masks. i was on the engineering track. what is engineering? i thought it was all about computer aided design. it was all about cadding and designing stuff and putting them together. it was fun, and i made good friends.

i was still rank 1. that’s all that mattered. and then i found out that the bio kids got a course to count as an honors course, and suddenly it didnt matter that i took 9 APs and 7 honors, because some kids got a gpa boost from some class i didnt know about. that’s not fair, engineering doesnt get one.

but engineering is easy, and microbioology is hard, so i cant complain. this sucked. a lot. my special number i had been working for was not going to matter, because someone could take that course and get a higher gpa. i couldnt take it, i wasnt a biology student.

in the summer before 12th grade, my dad asks me. what do you want to do in college? what is college? what is “do”? what is a major?

i went to some sat specialist guy who works right next to the post office and the chinese buffet that recently closed down. he sat me down and made me take a practice sat. a few hours and a few days later, my score comes to 1260. what is an SAT? why are we here? i am just a 17 year old who goes to high school, takes classes, gets As, doesnt really try, and takes classes.

what he said stuck with me.

what do you want to do in life?

honestly, your sat is good. you don’t really need to come here. you’re smart, but you’re not smart enough.

huh?? what do you mean im not smart enough. my rank is 1, my gpa is high, i take many courses.

well your sat is not 1600, and that’s what good colleges want

why do i need to go to college. who cares. the guy gets mad at me, and sternly says

in high school, i realized i needed to get my life together. you know, you cant stay in highschool forever. you have to grow up. i realized the friends i had did not take life seriously, and i cut them off, and i worked my ass off. i am successful now, and i like my life. i dont talk to my old highschool friends. dont be like that.

what the hell>>>>> life? im a highschooler. i go to high school, i take my classes, i get As, and i go to school. im a highschooler.

anyway, i realized graduation was coming, and i had to “apply” for “college”. i learned that they didnt like asian males in stem (for the record, idk how true this is), and i learned that clubs, and high gpas, and good “extracurriculars” and good letters of rec are how you get into a “good” college.

what is a good college? i dont know. today i still don’t know. so i write my PIQs, and my dad says, hey your cousin went to berkeley. he’s smart and he makes a lot of money.

i guess? what is money. so i have to pick my major, and i dont really know what i want to do. in fact, i never really considered that there was more to life that just going to class and taking classes, and getting good grades. so whatever i guess.

i guess i’ll just put interesting majors on a wheel, and spin them. so every school, i spun the wheel and it landed on something. aerospace, mechanical, computer science, engineering, whatever.

my parents said i was not allowed to do math, chemistry, physics, art, history, gender studies, psychology, agriculture, political science, anthropology… ; i had to do engineering (or stem). okay, sure fine. why not. they pay well. i guess i have to go to college.

so i applied. and i toured schools. i thought i was smart, so maybe i’ll get into a good one. i didn’t really care about college, i guess i’ll just join the best one i get into.

so, i got rejected from MIT, ok sure. fine. i guess. it was in rural illinois when i got rejected. i remember my dad saying in the car around 5pm, “oh well, happens”. sure, but i was told it was the best engineering college, and my number rank said it was 1, so it meant i was smart. okay, whtever.

then i got rejected from stanford, ok.

then i got rejected from ucla, ok.

then i got into uci, and sac state, and uc davis, and uci, and … other random colleges.

i got into ucsd also.

i also got into uiuc for cs+astronomy, because space was cool, and i guess i could do space stuff.

highschool came to an end. and i realized my rank was no longer 1. someone had beat me. the ceremony was interesting, i got a medal for being salutatorian. and the number i cared so much about, genuinely no one ever cared. i dont know why ic ard. it was so stupid. butwhaever, we went to sunsplash afterwards, and we had a lot of fun.

i guess i was going to college soon? my parents said i couldnt do uiuc (unfortunately), so i went to ucsd as a cs major.

what is computer science? what does it mean to code? what is a computer? someone told me it’s where smart people go in college. so im smart, why not. i’ll just go.

what i wanted to do in college

My first college experience was taking some summer engineering program to learn about computer science. My dad pressured me into taking an advanced intro to programming course, called CSE 11. I had never really done programming before this, so I was unsure if I was competent enough to do this. After all, it is university, and I found out I was pretty average, wrt my (soon-to-be) peers.

I met some cool people before going, and they were really smart. Way smarter than me. Up to this point, I had never really considered that there was another world out there, where there were kids who had been doing this engineering stuff for a few years. I mean, I guess I did engineering in high school, so I must know something.

Well, I did this program, and I met many outstanding individuals from around the globe. The bay area, OC, Pennsylvania, India, China, San Diego… you name it. It was a good program, but I quickly realized.

I am stupid. I really know nothing. I don’t know anything. I have spent 0 time on doing anything meaningful in high school. Clubs didn’t matter; I never was nationally or globally recognized for my efforts. My classes (save for AP Lit and AP Lang) were cartoonishly easy, and I didn’t really try in them. I don’t think I understood what it meant to “study” or to “grind out” some homework. I am stupid.

One moment I remember, was when a friend from some coastal California city, asked,

Hey, want to build an electric scooter together?

Sure! That sounds fun. There are SPIN scooters all around campus, and they’re fun to ride. They’re kinda expensive though. So we talked and planned about it in Revelle, at the spinning hammock-seat-thing.

The next day he comes back with a fully designed, fully working, simulation tested design on Fusion 360. My first reaction was, you can do simulations???????? This was when I realized, I know nothing.

Even worse, our CSE 11 study group exposed how little I truly knew. My classmates had already learned 2-6 programming languages, and worked on projects. One even sold their project to their high school!

I felt like a fraud. Do I really belong here? I know nothing. I am surrounded by people leagues smarter than me, who have accomplished many things before coming to college. Some already had finished their first “internship” and have published “research”.

I was told to an internship and do research, and join clubs, and do an internship, and do research, and do networking, and do my classes, and join an internship, and do research, and if I don’t I am behind, so get to finding that researchternship now.

Why was I here? I never really cared about college. I thought I could just take classes, and do well in life.

Anyway, I did what I did best, which was talk to classmates, ask for help, and study together for the final. I remember thinking how one of our classmates never went to class because he was so much smarter than the rest of us, and he knew so much already, so why bother? But I really enjoyed these study groups I made, because these smart classmates were willing to help me. I tremendously appreciate these early friends I made. I got an A.

And summer ended, and one of my friends who(m) I met on Discord, said he just finished his first internship. Wow, he is so smart. I should be like him.

my first year

My primary goal in college was to grind as many courses as possible, per quarter, and graduate my degree as fast as possible. From my 4 year plan, I estimated that I could finish college in about 2 years. I don’t remember what exactly motivated this, but

1. College was expensive and I felt bad making my parents pay for it.
2. Some of my friends were speedrunning their degree and I didn’t want to feel left out.
3. Your enrollment time is based on the number of units you have. More units = easier to get classes.
4. Speedrunning early classes meant I could get to the more interesting topics sooner.

Once I was done, I could find a good, high paying job, and work that for the rest of my life. And I would have a good life.

Around this time, my friends suggested I take some math courses with them. They suggested I take MATH 109, an intro to proofs class. I didn’t really like the idea. I thought it was unnecessary to my college goals.

But unfortunately, I got ragebaited by four of the smartest people I knew at the time to take it.

And good lord did I almost fail that class. I had never received such a low grade before. I remeber being at the local dim sum place with my parents during spring break, talking about how I was praying for a curve, and that I was going to fail. At the same time, I was taking Calculus II (MATH 20B), which was notoriously difficult (I could not understand the professor’s accent!).

But somehow I passed. And I thought, maybe I should take another math class. Around this time, my friend said, you should do some LeetCode. It was some platform where you can code up some solution to some programming puzzle. Haven taken CSE 12, I figured, maybe I should try some of the medium problems.

I could not do it, and I felt dumb. But this time, I didn’t feel that bad. I knew I was not as smart as my peers, so it was to be expected.

Spring quarter, I took MATH 184, a combinatorics course. This class was very difficult. I was juggling four classes, research, and some graduate seminar course. I remember spending like 5-8 hours everyday studying for this course.

I wanted to redeem myself. I was told I was smart, and that smart people get good grades. So I spent a lot of time, and I met very influential people who really changed my outlook on college. Somehow, I managed to get an A, because I was right on the threshold of an A-, and the professor curved it up to an A.

I was so excited. This was probably the third time in my life, where my hard work on one task paid off. Depressed the whole year, this was my (insert metaphor about light). I could not wait for summer break.

Summer changed my outlook on things. One memory I have is sitting in my friend’s car (who just got back from UCLA), driving us to our old high school to go say hi to our AP Lit teacher. It was the hottest summer in Sacramento on record, at 116 degrees Fahrenheit. He did no thave his AC on, and I was perplexed as to why. He mentioned how gas was expensive, and so the best he could do was keep the windows down. His parents didn’t really have money to buy him gas, and in fact, his parents spent all their savings on his college, and that none of his siblings could afford college.

Around this time, I became cognizant of the word “privilege”. I never really understood what it meant to be privileged. I never realized that my family was upper middle class, and that I had inherent advantages in life because of that. I never realized that college is (was?) a ticket to the good life for an American, and so I really needed to focus on this.

There were kids who never made it to college, whether by lack of funding, poor family support, institutional barriers, etc. And there were kids who were in really good colleges, who maybe didn’t really deserve it; they had access to better extracurriculars, tutors, whatever.

In conclusion, I was really lucky to be in the position I was in. My grandparents and parents have sacrificed (and I hate to be a cliche) their lives to put me in college.

I admit that around this point in life (which, embarrassingly, was quite late), I started to be more conscious about life.

• College was entirely paid for by my parents.
• I had a support system, and could always move back.
• I did not have to worry about housing, food, money, health, etc.
• ?

I never really considered why I was at university, only that I was there. School had never really been a place for me to learn, but a playground to visit my friends and brag about numbers that superfically measure intelligence. I mean, I don’t think I particularly wanted to be a Computer Science major; it was by change that I applied to UCSD with this in mind.

I never considered what I would do after graduating from school. There was always some nebulous vision of “employment” that would be there, waiting for me once I received my diploma. It was also around this time (2023), that CS job market for new grads and interns largely collapsed, in response to the ZIRP era and Covid.

I never reflected on my goals for college. I mean, the only reason why I wanted to graduate so early was because my friends were doing it, and I thought my degree was sufficient for post-grad success. A PhD was also not in my horizon; it was not something that would meaningful contribute to my potential employment.

I never understood what it meant to be “smart” or “intelligent”. As it turns out, there are many different “measures” or “metrics” one can use to size up another person. These are all overly reductive; does it make sense to judge (or in stronger terms, categorize them indelibly) a person by how much money they make? their test grades? their IQ? My insecurity of wanting to appear intelligent to my peers was illogical. One could easily construct any kind of reasonable metric to score an individual; in other words, you could define any arbitrary partial (or strict?) ordering (like a leaderboard) to any person, and rank them that way. Okay, I already knew this (having taken AP Psych), but I didn’t consider that you could add nuance (granularity) to these metrics.

I had to change. I needed to catch up.

second year fall quarter (sep 2024)

In my first year, I met a 4th year (he’s doing a PhD now!) who gave me some advice:

You should do everything. Become multidisciplinary. You never know what fields need software engineers. You’ll open many doors and meet all kinds of people!

At this time, I seriously considered doing a double major in Mathematics (pure, although applied was also on the table).

To be perfectly honest, I was ragebaited into taking math courses (I suppose nerdsnipe is a better term?). My friends said:

1. Computer Science is a fake degree! All you do is “import pytorch” and tune hyperparameters! Or import javascript library and connect frontend to backend!
2. You don’t learn anything particularly useful in CS!
3. I’ve already learned most of the material in high school and I thought it was boring.
4. CS is not rigorous!
5. I think you’re smart, you can do math.
6. If you’re so smart, why don’t you do something that would actually challenge you!
7. Math will train your brain to be better at {thinking about problems, analyzing problems, critical thinking, solving problems}.

But most importantly, I think I believed that completing a math major or doing math courses would make my friends respect me. I’m a little ashamed to admit that such a superficial reason was my primary motivator, but I knew that the math dept was also pretty lenient. I was against doing a math major for a few reasons.

• I felt that I was already behind my peers, not having done any competitive math in high school. I knew that this wasn’t a prerequisite for success, but I wanted to make the most out of my degree. Many of my CS/EE/CE + Math friends (not math-cs, that is an entirely different major) at the time had olympiad experience and were well decorated. Could I be like them? Did it matter?
• There was also an inherent opportunity cost. If I spent time on math, it would take time away from my CS degree, potentially hindering my chances of employment.
• Money was also a factor; I felt bad having my parents pay for an extra year.

In hindsight, this was actually a very excellent decision. I would have graduated around 2024, right around when the new grad/intern job market for software engineers was at its lowest point

insert data

I learned from MATH 184, that I could work/study/grind my way to success. Fortunately, I did not have to decide yet. UCSD is quite lenient with class enrollment; you can freely enroll in classes beyond the typical 16 units most students take, so I could enroll in my base 16 (pun unintended) and enroll in exta courses.

My friends (new set) at the time suggested I take Abstract Algebra I, MATH 100A.

First course in a rigorous three-quarter introduction to the methods and basic structures of higher algebra. Topics include groups, subgroups and factor groups, homomorphisms, rings, fields. (Students may not receive credit for both MATH 100A and MATH 103A.) Prerequisites: MATH 31CH or MATH 109 or consent of instructor. - UCSD Math Catalog.

My class schedule was:

• CSE 100R (Advanced Data Structures)
• CSE 101 (Design and Analysis of Algorithms)
• MATH 100A (Modern Algebra I)
• MATH 170A (Numerical Analysis I)
• CSE 95 (Tutoring)
• CSE 291 (Programmers are People Too)
• MATH 196 (Math Research Seminar)
• ECON 109 (Game Theory)

A total of 27 units. I also tutored CSE 11 (as part of 95), did a math seminar (196) and some form of research (CSE 291).

I was determined to spend a ridiculous amount of time to become successful. It was not clear to me (at the time) what “success” was; I figured that if I could achieve the necessary skills to get a internship, I could get find some kind of post-grad success. I spent maybe around 12-17 hours each day for 10 weeks, hoping that these insane hours would force me to work.

I would say that this was my most impactful quarter at UCSD. I met an incredible number of people who I still consider close friends today. It taught me that I really, truly, could do anything I wanted so long as I set my mind to it. And that I had an uncountable number of friends to depend on when I needed them (and vice versa).

Tutoring was also a great experience. I was able to respond to ~130 Autograder tickets for the entire quarter (this was before LLMs took off, replacing tutors). As of writing this, I would consider myself close to \approx a quarter of my colleagues.

MATH 100A was a beautiful class. It was the first time where I could understand why math was so beautiful. Most math in grade school is about following instructions, mechanically number crunching equations until you resolve an equal sign. It’s not motivated why things work, just that there are numbers, addition, fractions, squares, spheres, permutations, complex numbers, derivatives…and so on. The reason why you study abstract algebra is quite interesting, and I urge you to read it here.

I think it’s better to give an analogy.

Imagine you have been tasked (you may assume some omnipotent outer space aliens have delegated this to you) with visiting art museums (they really like art) your whole life. Everyday, you wake up, and your magical car (this analogy works with a bus, train, and other forms of mass transit) that never wears down and requires no fuel to operate, takes you to a new art museum. You can stare and read the descriptions, but sometimes they’re in a different language, but it’s fine because your job is to visit art museums. Of course we all die, and there are more art museums than the number of days a human lives on average (citation needed?).

Art museums don’t appear out of nowhere; someone has to put them there. Maybe you could try “art”.

The aliens provide you a blank canvas and one oil-based paint of blue. They say you can paint whatever. So you pick up your brush gently swipe across the canvas, the hairs slowly losing their color as they leave less and less behind.

Your new task is to paint. So you paint, paint, paint. Great, you made the sky. Great, you made the ocean. The aliens, bored, give you a new color. So you paint, paint, paint. They become bored, give you a new color or a new brush, and you paint, paint, paint. You draw countless murals. They illustrate everything: bears, trees, rivers, lunch from last week, a children’s novel, ufo libraries, how you felt when that crow accompanied you for lunch, wonder…

Each time the aliens come back, you can express yourself in ways not possible before.

This class allowed me to build a system of mathematical structures and tools that built upon one. It was also satisfying to be able to understand these abstract objects in my head.

Importantly, I was beginning to appreciate the opportunity to go to school. I could choose want I wanted to learn about and do it. I was still concerned about my grades, but I held them in much less regard.

Anyway, the stress eventually got to me and I never took this much workload again. Despite doing well, I did not feel comfortable enough in applying for a double major.

rest of second year

This was kind of a blur. Winter quarter was quite uneventful. I had no internship for the summer yet, so I kept working. My study partner for MATH 181A “Introduction to Mathematical Statistics I” inspired me to focus more on studying LeetCode (I made very little progress) and talked about his dreams and aspirations after college. It felt silly to me that I should be thinking about post grad, considering that it was ~2.5 years away and I had no idea what I wanted to do for my career.

I mean sure, I was going to do computer science, but what in cs? AI/ML seemed interesting; LLMs were a pretty exciting technology. I guessed I would be writing some kind of code, maybe in Java or C++. Definitely did not want to frontend work!

Another stressor at the time was. Actually, I think this was one of my more pleasant quarters.

just had a pizookie
they are mid
i just sent my double major req yesterday
it was rejected

Spring quarter came and I wanted to take some time away from my math degree and focus on the computer science part.

The most impactful courses I took were

• CSE 150B (Introduction to AI: Search and Reasoning)
• CSE 224 (Graduate Networked Services)
• CSE 120 (Operating Systems)

I am very thankful that my friend suggested I take 224. Every single interview I’ve had has asked questions related to the material. It was also the first time I was “significantly skill-gapped” by the other students there. The final project had a lower quartile of ~20-25% and about 1/5th of the class (50/200) was caught with academic integrity violations.

Around this time I took up reading Atiyah’s Introduction to Commutative Algebra, with some friends, under the guidance of a graduate student. This was a totally voluntary activity, something entirely unrelated to my career aspirations.

And out of nowhere,

5/22/24, 1:30 PM i got an internship offer

and I got a resident assistant offer (figured out housing for next year!). PLUS I got my double major approved.

So life was good. But I still didn’t really know what I wanted to do with my degree(s).

summer between 2nd and third year.

I don’t remember what I spent on with my first paycheck. I do remember thinking that work was pretty fun. In my free time I did some studying on Lean4 and Rust. I was getting involved in math research and the work was pretty interesting.

In the month before school, I wanted to work in something “not devops” (interesting, but becomes boring quickly). I decided that I would focus a significant amount of my time on preparing myself for interviews for the following summer.

third year

autumn (fall)

In third year, I took

• CSE 127 (Intro to Computer Security)
• CSE 151A (ML: Learning Algorithms)
• MATH 160A (Mathematical Logic I)
• MATH 20D (Ordinary Differential Equations)
• MATH 199 (Math Research)
• CSE 198 (CS Research)

This was a good quarter. Computer security was interesting, machine learning was bad (all I will say about it!), 160A was ridiculously difficult, and diffeq was horrible.

I spent more time on my interests. My math research was primary on formalizing an important commutative algebra theorem In Lean4. My CS research was on applying Lean4 to formalize this textbook, Concrete Semantics. At the time I thought computerformalization would take off, imagine a world where all math theorems have been converted to Lean4 and formalized in some library. Maybe LLMs could generate code to formalize it too (this turned out to be a pretty accurate prediction).

Fall was pretty uneventful. I did secure an internship for next summer in December.

winter (fall v2)

MATH 140A is the hardest class I have taken. It is the math department’s Honors Real Analysis in Rudin. Some perspective:

• I spent approximately 30-40 hours each week on this class.
• My colleagues were very intelligent people. There were folks from other majors (bioengineering, electrical engineer, computer engineering, computer science, linguistics…).
• 74 students were enrolled in Week 1
• 42 students were enrolled in Week 3
• 36 students took the final
• Only students who plan to do a Math PhD are recommended to take this class.
• Without curve, only one person passed.

By the end of the class, I think we had one big study group with 10-12 people in it. There is friendship in collective suffering.

spring

Spent a lot of time working on keyboards, water bottles, and dealing with tariffs. Got into grad school.

The biggest thing I learned was that engineering is hard. Real engineering is hard. My friends Samir, Anthony, and Cody took CSE 145/237D. The goal of the class is to build some embedded systems project and write about it. We decided to built a smart water bottle with an eink display.

There’s so much that needs to go into a smart water bottle.

1. All the eletronics need to be kept inside a secure, waterproof container.
2. The water bottle needs to be battery powered, so it must provide a way for the user to replace the battery WHILE ensuring (1).
3. The eink display needs to show useful information and needs to be protected from water.
4. We had various sensors that protrude from the cap into the container to measure the water.
5. The water bottle needed to have bluetooth functionality.
6. Cheap.

I found out:

• Buying american-made products is expensive. They also took a long time to build and ship.
• Working with Eink displays is hard. The spec sheet was mixed between Chinese and English, with a lot of missing or undecipherable information.
• Mass manufacturing is magic. How does one produce 10,000 aluminum water bottles as cheaply and efficiently as possible? Even if we assume a very bad water bottle like a soda can, you need to:
  • source the materials
  • ship the materials
  • refine the materials
  • buy machines to do all the above
  • make sure the machines dont break, and when they do, fix them
  • make a design
  • print/build the design
  • realize the design is poor, so you have to redo it
  • have a machine that molds/cuts/assembles the bottles together.
• Supply chains are unbelievably complex. It is a miracle they work at all.
• Cost is not the only reason american manufacturing will never take off.
• Writing firmware is difficult. Iteration times are much longer than software.
• You are reliant on vendors providing correct information (if any).
• Any kind of engineering requires a team with a wide variety of skills. One person cannot know the entire stack from the bottom up. Big project -> many teams -> how do these teams talk to each other? hierarchial doesn’t sound efficient -> product manager.

I also built the Charybdis keyboard (after ordering the DIY kit). 3D printing is so hard. I probably reduced my lifespan by a few years resin printing the keycaps for this. In the end, I ended up purchasing a basic set off of Amazon.

Went to SCaLE (SoCal Linux Expo) in Pasadena.

I was pretty content in life. Looking back, I think my 1st and 2nd year self would have admired 3rd year me.

fourth year

I’m so old. I feel so old. Most of my friends have already graduated at this point. I used to spend long hours in the CSE basement. If you stayed there long enough, you’d bump into the same people all the time. I would call them “basement goblins” (for the record I was one too).

In fourth year, I spent a lot of time wandering in the CSE basement, hoping to find someone I recognized from previous years. Sometimes this was successful and I could study with them in b250.

Reflecting on my previous years, I achieved all the goals I set out to do, even before my second year.

1. get an internship
2. get an internship outside san diego
3. explore cs research
4. explore math research
5. travel san diego
6. travel with my own money (did this in March!)
7. graduate with a double major
8. make a lot of friends
9. mentor underclassmen (i am a big believer in paying it forward)
10. work on projects with friends (did so many)
11. complete MATH 100AB, MATH 140AB
12. visit/enter every ucsd building
13. tutor
14. eat a lot of vallarta
15. win a hackathon
16. Finish a Daniel Kane course

What do you do when you accomplish all your goals? I was satisfied, but I felt that there was a lot more I could have done.

When I accomplished these goals, I didn’t really celebrate. It felt like something I had to do as part of my degree. I don’t think I was the one that set these goals for myself. I mean, in today’s job market, it’s kind of impossible (very difficult) to get a full time offer post grad without some form of an internship.

By default, goal 1 (and by extension goal 2) are not really goals, but part of my degree. Goals 3 and 4 were something many upperclassmen told me I had to do because UCSD is a good research school.

Goals 5 and 6 could be completed without going to college.

I celebrated goal 7, 10, 11, and 16. For the past few months I felt that I seriously did hurt my employment opportunities because I spent time on math instead of cs. I think to some degree, my initial fear came true; however, I think goal 11 was something I wanted to do. I remember telling my father that I would pass this class, and I was doing it to prove myself I could. If I didn’t do those four classes, I don’t think I would have meaningfully achieved 7 (this is not to say you aren’t a real math major if you didn’t take those four classes). Goal 16 was because DK is famous and is known for having hard classes.

8 was not particularly difficult. Some people have asked me why “I know everyone” (I definitely knew of many folks, but I don’t think I can claim being friends with them).

My advice:

• I think try to make friends with only people who are “cracked” is a bad idea.
• Network effects are really important. A lot of my friends are “friends of friends”.
• An easy way to expose yourself to more people is to get really good at something and have it be well known (DO NOT GLOAT!).
• If you see someone you know, say hi! One habit I have is always scanning a room or some visual area to see if I recognize anyone.
• Get in situations where you can interact with people. Some algorithms will call this “expanding the frontier”. Expanding your frontier (people you know of) will lead to more friendships.
• Making connections to “network” usually doesn’t work in my experience. People will want to “network” with you if you also have something of substance.
• Be yourself.
• Goal 9 and 10 helps!
• There is friendship in suffering. Taking a hard class and joining a study group helps.

The rest of the goals were trivial.

lessons?

So I am supposed to write about the stuff I learned. Okay. I guess you could just read the story and figure it out yourself. Or maybe you can Ctrl+ACV into your favorite LLM of choice and get a good response. Honestly, I don’t think this blog post provides much substance.

Someone once asked me, how do I do it. How can I balance taking many classes, social life, and sleep. There’s this famous triangle:

One trick I learned was that you can force academics and social life to be closer to each other. In particular, if you surround yourself with like-minded individuals (grind above all), it’s easier for them to understand if you can’t attend a hangout (although in >80% of cases, you should go hang out with them) or will work with you. Many of my friends were from study groups I met from Discord or from classes that prioritized group projects.

Sleep is non-negotiable. I realized I needed a minimum of 7 hours of sleep, and anything less than 6.5 will mess up my week. (I suppose you could abuse caffeine,,,).

My website’s motto is

obsession > discipline > motivation

Motivation is fake. Many times I was motivated to take a class or work on some sideproject, but I was never able to finish. Most things worth doing are not easy, and you might not have the motivation to do it.

You need to be disciplined. I was only able to handle heavy course loads because I was disciplined. Wake up, lock in, eat, shower (optional), lock in, sleep.

If he cared enough, he’d do it for you.

If you’ve been around on the internet, you may have heard the above phrase. We can apply this same principle to discipline. If you really cared about your class/project/employment/friendships/… you’d find a way.

I spent a lot of time in first year talking to many talented students. There were many things all of them had in common, but I remember that everyone was obsessed with something. Everyone was engrossed in their niche and were always willing to talk about it. If you’re constantly thinking of something, you’re already half way there!

I think a lot of my school/career decisions were because of ego. I mean, I had no reason to take 140a. I had no plans to do a math phd, nor did I think I was cut out to do math research. The concept of a “phd” was entirely foriegn me. But I took the class anyway because I thought I could pass it. I didn’t need to take so many classes each quarter (I graduated 1 quarter earlier).

Okay, maybe it’s not actually ego. Arrogance? Courage? Narcissism (clout chasing)?

One day I was walking home from the library, stressing about tomorrow’s midterm. There was no way I going to pass. After some reflection, I could not remember when I last failed.

When was the last time you failed? Specifically, when was the last time you seriously failed at doing something that was entirely (or mostly) in your control either because you were legitimately incompetent or lazy (or something else, but I’m blanking on a good adjective that would satisfy the rule of 3)?

I could not remember! I will succeed because I have always succeeded. Why would tomorrow be any different? Why does it matter? If I fail, I fail, so be it.

unwavering (adj.): continuing in a strong and steady way

You must be unwavering. Be stupid about it. Can’t do something? Yes you can. Go do it.

Okay, that sounds like something you’d find in a book for CEOs titled “The Art of Business Execution: A Path to Glory”. I knew a LoL player who was briefly top 10 in North America and one of the best players in the world for his champion. Every game, he would say

ez win

even when it was a bad matchup. I asked why. He explained that the idea is to mentally prepare him for each game so he can play at his best.

Anyway I don’t feel like elaborating on this story anymore, but I think you get the idea.

taking math courses

A lot of cs/swe folks glamorize mathematicians (and physics, and other “hard” sciences) and the work they do. I was (and still am?) one of those people. When underclassmen ask me for advice, I always tell them to take some math courses.

Looking back, I think this advice is hard to justify. I mean, I took a lot of math courses, and I don’t think it really helped me get a job. It was fun, and I learned a lot, but it didn’t really help me get an internship or a full time offer.

However, I will say that it did help me think more deeply about problems. It also helped me appreciate the beauty of math, and the way it can be used to model the world. I felt that I could understand cs problems better than my peers who didn’t have a math background. In my opinion, math knowledge (beyond the basics like calculus and linear algebra) is not necessary for software engineering and this has a pretty poor roi, but they have huge potential roi. It’s just a lot harder to realize the benefits of a math education (i am saying this, knowing some pure/applied math majors who not doing grad school or some form of computing-adjacent job).

3rd year me would say, “if you have the time and resources, take some math courses! You’ll learn how to think about problems better!”.

4th year me would say, “it’s not really that important”.

However, if I were to repeat college, I think would have still double majored in math (although I would spend more time on applied math courses to do scientific computing/engineering).

addendum

thank you to the friends who helped write this.
