Hi! I'm Wan.
Random fun facts:
- I believe that I'm the first (and only) Bruneian
undergraduate PhD student at CMU.
- I believe that I'm also the first CMU CS undergrad to graduate with two SCS concentrations, though that's mostly from being the first concentrations batch and stumbling my way into it.
- I've helped to raise chickens. This fact seems to spark joy in some people.
I like systems programming, distributed systems and databases in particular. I’m generally interested in the tradeoffs that people make between speed, memory, formalism, and communication.
Beyond that, I'm interested in learning more about practical applications of randomized algorithms and approximation algorithms. MESH is one of my favorite examples of what I mean. Randomness seems to be a resource that we aren't exploiting much yet.
I'm interested in but realistically not getting back onto the data science hype train. The same goes for cybersecurity.
I have essentially stopped playing DOTA2, League, and CSGO.
I enjoy creating teaching material, typically aimed at an introductory level. I particularly believe that everyone should have access to good learning resources (whether they make good use of it or not is up to them). If you're doing something in this space, I'm interested.
I spend an inordinate amount of my time sleeping, reading about food, or browsing cute subreddits. Some good and slightly lesser-known YouTube channels:
(Research papers not included, fiction not included.)
I personally prefer hardcopies of books and buy books that I consider to have high value. This list only contains books which I have bought or read significant parts of. Always happy to take book recommendations or reviews!
- Trying to read a bunch of research papers. Book reading temporarily on hold.
To be continued:
All of Statistics.
I like the presentation of the book and hear good things about it.
I'm dubious of appeals to nature and stuff like that in a number of introductory machine learning texts, so I am looking forward to reading this book's treatment of the topic.
The Shellcoder's Handbook.
On my bookshelf overseas. Got me started with basic binary exploitation. Progress was slow in high school. Should be much faster now that I've written an operating system kernel.
Practical Malware Analysis.
On my bookshelf overseas. Got me started with basic reversing and detection avoidance. Progress was slow in high school. Should be much faster now that I've taken 15-213.
To be read some day:
A Book of Abstract Algebra.
On my bookshelf. I don't remember anything from taking Algebraic Structures and have no intuition whatsoever. Definitely was not ready for Dummit and Foote back then.
The Nature of Computation.
On my bookshelf. Nicely written book from a new point of view (Moore is a physicist). Covers a mix of topics from algorithms and undergraduate complexity theory.
Mathematics: Its Contents Methods and Meaning.
On my bookshelf. I have extremely shaky foundations in math, in particular my geometry is nonexistent. This seems like a decent way of shoring it up.
To be re-read:
- Performance Modeling and Design of Computer Systems.
The material didn't sink in the first time (15-359), and it didn't really sink in the second time either (15-857), so maybe the third time is the charm. To be clear, that's mostly a me problem. My goal is to be able to quickly estimate "X workload? Deploy Y servers in Z configuration".
Would love to read, doubt it will practically happen in the next decade:
Practical Foundations for Programming Languages.
Didn't really read this enough while taking the class.
I think formally verified things will be the future, just not "in my working lifetime" future.
A Textbook of Modern Toxicology.
I was really into this book at some point. Good for going on Wikipedia binges.
Have read, can recommend:
A Teacher's Race Course.
This book is a little different from the others on the list.
It was written by a teacher of mine who has since passed away.
She strongly influenced my teaching beliefs and guided me towards a more positive outlook of the world. A key part of her teaching philosophy is to treat and genuinely care for students as people first and foremost. She had a reputation for being able to turn even the most misbehaved and poor-scoring set of classroom monkeys into competent students. Anyone who wants to seriously improve their teaching would probably benefit from reading this book.
This book gets it. I typically roll my eyes at most college student discussions of economics or poverty, but this book provides an understanding and empathetic view to questions like: "why don't the poor save more? why don't they invest in their future? why don't they use free mosquito nets? what interventions actually work?", and so on. Good and varied selection of case studies, engaging discourse. If I had read this at an earlier stage in my life, I might have gone into economics.
The Web Application Hacker's Handbook.
On my bookshelf at home. Gentle introduction to exploiting web applications. I was able to follow along and directly apply its lessons to real-world web applications in high school.
I would like to work on these at some point. Inspiration is generally an issue.
- Falls are the leading cause of injuries (fatal and otherwise) for older people. I’ve envisioned a cheap wearable everyday fall-arresting device, targeted towards the elderly and infirm. I haven’t been able to come up with a reasonable concept, though, and I'm bad at hardware problems. Dumb ideas have included weight shifting clothing, quick inflating swarm quadcopters, and airbag-esque pockets. You could also repurpose something like ReWalk, presumably, but that’s way too expensive.
- (A little depressing) Recently, I've been thinking more about pagpag. Fundamentally, I believe that most people that I've met would be kind enough to give up their Starbucks or bubble tea or whatever it is if they could donate directly to people like those in this video. I don't really know what a solution would look like in this space -- can you use technology to reach and help people who fundamentally have zero access to technology? For less extreme cases, GiveDirectly is an interesting manifestation of this idea (households need at least SIM cards afaik), and ActionAgainstHunger is a generally safe choice as far as food charities go (93 cents on the dollar). Both are pretty well rated charities.
