50 Lessons I’ve Learned Over the Last Six Years

Sun, 01 Mar 2026 22:45:44 -0500

These are some things I’ve learned, or at the very least thought about, over the last few years. Hopefully some of these ideas are useful to you as well.

Some Interesting Things I’ve Read/Watched: Link Dump #5

Sun, 22 Feb 2026 21:00:04 -0500

I am still trying to get rid of my backlog of links I wanted to post about, so please bear with me.

Some Interesting Things I’ve Read/Watched: Link Dump #3

Sat, 08 Nov 2025 00:20:43 -0500

Hi! Here is a linkdump. I told myself I would post these with really minimal context because I am too busy to summarize these things and have a really giant backlog of links I’ve been wanting to post, but uh, the writer in me won out and I failed. Some of these have way more description than others. But I do also have quotes I’ve pulled for some of them, so maybe that will help make this post more interesting.

What Makes a Graduate-Level Course Different From a Senior Undergraduate Course?

Fri, 17 Oct 2025 23:38:36 -0400

About a year ago, while I was only a few weeks into the first graduate-level course I ever took, I tried asking a bunch of grad students what the difference between taking courses at the graduate level and the undergraduate level is. Being researchers in training (researchers are, in my experience, terrible at explaining themselves), they gave me delightful non-answers such as “it’s not that different” (this is a lie) and “your professors treat you like adults” (whatever that means).

Linkdump: Interesting Things I Looked At (Very) Recently (2025-08-12)

Tue, 12 Aug 2025 23:07:33 -0400

Most of these are from today, but some are from yesterday, and a few are from last week. The descriptions will be short, since I am short on time.

Some Interesting Things I’ve Read/Watched: Link Dump #2

Mon, 30 Jun 2025 15:34:26 -0400

Here’s another linkdump—a list of links to stuff I thought was interesting but likely won’t get to properly reviewing any time soon.¹

I reserve the right to more fully review any of these article at a later date, of course. (Though at this point, it’s extremely unlikely to ever happen.)

Lessons I Learned During My Undergraduate Research Internship

Fri, 27 Jun 2025 23:37:43 -0400

I really meant to put this list up sometime last fall… whoops. (This is yet another incredibly overdue article.) Anyway, here are a whole bunch of things I learned while attempting to “do research” last summer, whatever that means. The big theme here is to make life easier for future you, who will have to wrangle together your several months of chaos and exploration into a rigorous and coherent narrative. Present you can help by being organized and breaking things down into smaller, documentable steps.

Reading Academic Papers Is a Nightmare

Sat, 21 Jun 2025 12:03:33 -0400

So I’ve been saying for a while that reading academic papers is a skill. However, what I didn’t realize is that having a pretty good idea of how to read a paper from one discipline doesn’t quite map to knowing how to approach a paper from another field. Academic papers are all confusing nightmares, but papers from different disciplines are nightmarish in different ways, which means that while some parts of the basic reading approach can stay the same, others will have to be discarded or relearned.

Getting to the End of the Thought; or, Why Write in the Age of AI?

Fri, 06 Jun 2025 00:14:25 -0400

I’ve been thinking a lot about the value of writing recently, especially in regard to how it’s been influenced by the advent of generative AI. In the past few months, I’ve had a lot of conversations in which people claimed that generative AI is just as good at writing as humans now, or better, in many cases. While I agree that AI generation tools are, at this point, better at the mechanics of writing than the average person, I have always found their outputs to be shallow and devoid of interesting surprises.

You Need to Be Proactive

Sun, 30 Mar 2025 11:29:39 -0400

One of the things that has been repeatedly drilled into me over the past year or so is the fact that if you want people to do things for you, you’re most likely going to have to harass them. (I don’t mean literal harassment, by the way – please don’t commit a criminal offense and say I encouraged you.) This is true especially when working with highly busy people like managers and professors. If you want something, you can’t just assume they’ll intuit that and give it to you – you have to ask (and assume they’ll forget, then ask them again). If you need them to do something for you, you’ll need to remind them, and inform them of the deadline, likely multiple times. Everyone has their own problems to worry about and the thing you need might not be top of mind. The burden of remembering is on you.

Some Interesting Things I’ve Read/Watched: Link Dump #1

Sun, 16 Mar 2025 22:07:57 -0400

I keep coming across articles (and occasionally videos, and occasionally fiction or poetry) online that I want to share and comment on, but I recently realized that I will never have time to fully comment on everything I read that I find interesting. So I’m pulling another page out of Cory Doctorow’s book: here is a dump of links to cool stuff, along with some (hopefully very) brief descriptions of why I found these articles interesting. (Also, here is a link to a link dump where Doctorow ¹ talks about link blogging. It might be interesting for you to look at.)

Some Things I Learned From Writing My First Research Report

Sun, 16 Mar 2025 20:24:12 -0400

Last summer, I was tasked with writing a report about the research I completed and submitting it to my supervisor by the end of the summer. I, of course, had never done this kind of writing before, so I learned several lessons. The hard way. The learning process was super painful, but it did come in handy when I had to write two other research reports in my classes last fall. Here are a few of the lessons I learned.

I Am Slowly Discovering That I Have No Idea How to Read

Fri, 07 Feb 2025 14:55:31 -0500

Over the last month and a half or so, I’ve come to the conclusion that I actually don’t know how to read, which is definitely a jarring realization to be having after over 18 years of formal education.

Okay, maybe I’m being a little bit cheeky here. I am not literally claiming to be illiterate or even functionally illiterate, and it would be stupid of me to do so, since clearly I am writing this blog post and have written many other blog posts where I reviewed books. However, one of the things my high school education didn’t prepare me for, and that my four years of training and education in engineering and computer science have completely failed to teach me, is how to both get through and learn from – “learn from” is the key term here – a large volume of readings on a weekly basis.

Why Does Theory Matter in Computer Science? (Part 2)

Fri, 24 Jan 2025 12:47:46 -0500

In the first part of this talk, I made the case that theory is useful because it allows us to find (or at the very least, have the correct toolkit and language to explore) solutions to real-world problems. In this part, we are going to look at some examples of such problems and develop mathematical language to be able to discuss them more abstractly. I’ve put the term “real-world” in quotes in the title, because I’m going to be talking about these problems in a lot of generality. However, I want to stress that specific instances of these problems are actually relevant in industry, and I think it’ll be easy to see why once I start talking about them.

Some Interesting Things I’ve Read Lately, Episode 2

Mon, 30 Dec 2024 20:08:03 -0500

Here’s another roundup of some interesting things I’ve come across lately and would like to talk about! As always, I’m sure there’s some great stuff I read but cannot for the life of me remember.

This one is extremely late, since I’ve been incredibly busy and finding time to write has been hard. I think I looked at some of this stuff back in… November? October? Oops. I’ve decided I want to keep these to only 4–5 items per post, so more posts should be coming shortly! There are definitely other things I’ve looked at that I want to talk about.

Research Papers Shouldn’t Be Read in Order; or, How to Read a Research Paper

Mon, 30 Dec 2024 13:44:15 -0500

I just finished a blog post where I discuss things I’ve recently learned about how to read research papers. I almost included this as a point in that post, but I think it’s important enough to warrant its own article.

Here’s the idea: you absolutely should not be reading the sections of a research paper in order.

It took me a while to learn this one – I can’t remember if I first read this advice somewhere, if someone told it to me, or if I reverse-engineered it from advice I got about how to write papers. It doesn’t matter which one came first, really – my point is that I only found this out in a roundabout way through googling and trial and error and harassing people with questions.

Research Reflections: On Reading (Math and Math-Adjacent) Academic Papers

Sun, 29 Dec 2024 23:51:14 -0500

Last summer, I spent a good chunk of my time doing an undergraduate research project during which I worked on a project largely by myself, under the supervision of a math professor. I then took a graduate level course in a related area this fall, where I investigated the theoretical underpinning behind my summer project. I had no idea what I was doing or what I had gotten myself into. As a result, I learned a lot, and tried to keep note of the various things I had learned. This is the first installment, on what I learned from trying to read math and theoretical CS papers.

Why Does Theory Matter in Computer Science? (Part 1)

Sun, 29 Dec 2024 00:38:01 -0500

If you’re a computer science student, you probably had to take an introductory discrete math course at some point. Did you enjoy it? If so, this talk probably isn’t for you, so you can feel free to skip the rest. (Or not – hopefully you feel like you can still learn something from me!) Jokes aside, it’s actually okay not to enjoy your intro to discrete math course: like, personally, I loved mine, but I also completely hated my discrete probability course and would prefer never to see it again. But I pick on discrete math because I feel like if it’s taught well, it can be a turning point for many people, and it certainly was for me.

Some Thoughts on “Academic Training”

Sat, 28 Dec 2024 10:36:42 -0500

I’ve long said that university education starts to make a lot more sense if you look at it as a precursor to academic training. Historically, there have really been two major types of undergraduate university training, in my opinion: there was the liberal arts type of education, which was meant to turn rich people into cultured members of society (several of whom then went on to pursue academic training and scholarly activities, because they were rich and could afford to do so), and the more specialized type, which is meant to make the student literate enough in the major foundational ideas of the field to pursue additional training at the graduate level. If I remember correctly, universities functioning more like businesses is relatively new, the idea of university being a place for vocational training is relatively new, and the idea that most adults should get a university degree to be employable is also relatively new. (Also of interest: see “credential inflation.”)

How to Watch a Technical Research Talk (or Workshop, or Tutorial) Recording (and Make the Most of It)

Sun, 24 Nov 2024 22:13:50 -0500

When I’m trying to approach a highly specialized topic for the first time, one of my tactics is to find a recording of a research-geared workshop about it and watch it as my introductory crash course. The benefits of this are as follows:

I am learning about the subject from (hopefully) a credible expert in the field.
Workshops and talks usually try to be self-contained, which means basic background info will likely be given and I won’t have to pore through 10 different research papers, searching for an obscure definition, in vain.
Talks typically have the benefit of including visuals and informal intuition conveyed by the speaker, which generally won’t make it into academic papers, because they’re not rigorous. However, the visuals and informal statements and intuition are invaluable for gaining a better understanding of the information.
The speaker will generally include a bibliography and mention related works, which is a great jumping off point for further investigation and saves me from having to figure out what the seminal sources are myself.

However, there are also some drawbacks:

Hypergraph Theory Basics

Fri, 22 Nov 2024 22:35:01 -0500

Graphs can be seen as a way to represent pairwise relationships between objects. With graphs, we have one object type and one relationship type. In one of the most common canonical applications or graph theory, social networking, we are trying to understand and represent social groups using graphs. In that case, our object is people, our pairwise relationship is friendship, and two people have a relationship between them if they are friends.

What Reading a Research Paper Feels Like

Wed, 20 Nov 2024 07:43:10 -0500

You’ve started a new job, you’ve stumbled into a conversation that’s been happening for several decades, and you’re feeling way too lost to even begin to follow what anyone is talking about, let alone participate. You’re confused, so you go see John, who seems to be semi-acquainted with the people having the conversation. You briefly sketch out what (you think) you heard, and tell him that you didn’t really understand anything anyone said. Maybe he can help you?

Some Interesting Things I’ve Read Lately, Episode 1

Fri, 16 Aug 2024 23:51:41 -0400

Here’s a look at some of the articles and books I’ve been reading lately, or at least, the ones that stuck out to me. Originally, I wanted to do this as a weekly series, inspired by Cory Doctorow’s link posts where he comments on various articles he’s read - but I don’t have that kind of time. Also, I’m really not that great at remembering the various articles I’ve stumbled through online, so you’re going to get these when you get them.

How to Be a “Talentless Hack” in Public

Sat, 20 Jul 2024 22:00:41 -0400

When you call yourself a “talentless hack” (which you probably don’t, but you might if we share a similar sense of humour), it’s likely for one of two reasons: either you’re caught in a situation where you suddenly have to perform or get results or do something, with zero experience or knowledge of what’s going on (at which point feeling like “a hack” is somewhat legitimate), or you’re doing it out of self-deprecation because you have imposter syndrome.

Some Advice for Taking Your First Proof-Based Math Course

Sat, 10 Feb 2024 00:00:01 -0400

If you are like me, you did not particularly enjoy math in high school, so the idea of learning an entirely new type of math in university might be terrifying to you. I know this can be scary and overwhelming (it was for me!), so here are some things I learned when taking my first proof-based mathematics course. Hopefully you find this helpful.

"Learning" Textbooks vs "Reference" Textbooks

Sat, 10 Feb 2024 00:00:00 -0400

One of the things I’ve been thinking a lot about lately is the fact that there are two main types of textbooks. There are reference textbooks, which are for people who are already versed in the subject area, typically academic researchers, professors, and the like. They tend to be large, contain massive amounts of information, and be unintelligible to everyone but their target audience. Then, there are expository textbooks, which are for people who actually want to learn things (aka me, a confused undergraduate student).
