Page: Feed: --- ## [LLMs are Making Me Dumber](https://vincent-cheng.com/llms-are-making-me-dumber/) _2025-05-14 · Vincent Cheng_ Here are some ways I use LLMs that I think are making me dumber: When I want to build a Chrome extension for personal use, instead of actually learning and writing the JavaScript, I Claude-Code the whole thing in a couple of hours without writing a single line of code. Instead of taking the usual route which would leave me with more actual familiarity with JavaScript, I now shortcut the process,… ## [1% Improvements](https://vincent-cheng.com/1-improvements/) _2025-03-06 · Vincent Cheng_ Here’s a running list of tiny workflow tips that make my day-to-day noticeably smoother. Most of these are embarrassingly simple, but that’s the point! Habits that seem obvious to me might be totally new to someone else (and vice versa). I will continually update this every ~month and try to only include things that I have kept up using for more than a month. Message me your favorites… ## [Now](https://vincent-cheng.com/now/) _2025-02-10 · Vincent Cheng_ What I’m Doing Now (updated 7/19) Working at METR over the summer on some CoT monitoring projects! In Berkeley/SF ## [About](https://vincent-cheng.com/about/) _2025-02-10 · Vincent Cheng_ Hey, I’m Vincent! I was a freshman at UCSD and am a sophomore studying math at Cornell now. I change my mind about things very often, but wanting to learn new things is a constant! I’m especially interested in math, ML, AI safety, Brazilian Jiu-Jitsu, and meeting new people. Message or email me if you want to talk! Things I’ve been a part of and enjoyed: Ross , WARP , Atlas ,… ## [Metal Pins Simulation](https://vincent-cheng.com/metal-pins-simulation/) _2025-02-09 · Vincent Cheng_ This web app uses your webcam, a lightweight depth model, and three.js to recreate that oddly satisfying metal pin toy effect. Try it out here . Try out the simulation for yourself here and check out the code here . ## [15 Questions](https://vincent-cheng.com/15-questions/) _2025-02-04 · Vincent Cheng_ What do truly long-context models look like? I want to give the model all my journals, notes, pictures, previous work, etc. so that it can make connections and tailor responses for me. I imagine this to be In-between context stuffing and fine-tuning. Every ~day, the model takes all the conversations from that day and decides which to use to update its weights. In the future, will everyone have… ## [Ideas](https://vincent-cheng.com/ideas/) _2025-01-17 · Vincent Cheng_ Some ideas I find interesting but don’t have enough time to make a reality. A “See all context” button. This is especially useful for reasoning models since I want to know which parts of the reasoning were dropped so I know how much context to provide. You would have to drop sensitive information like like system prompts. JARVIS. Models are capable enough already! We just need… ## [Quotes](https://vincent-cheng.com/good-quotes/) _2025-01-14 · Vincent Cheng_ The Man In The Arena It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming;… ## [The Best Sport](https://vincent-cheng.com/the-best-sport/) _2025-01-04 · Vincent Cheng_ Brazilian Jiu-Jitsu (BJJ) is a grappling sport which means there is no punching or kicking and you win by gaining dominant positions or submissions such as chokeholds or joint locks. What Makes BJJ Different? BJJ is the “broadest” sport I’ve done. It feels like math in the sense that you have so many distinct, but related, concepts to learn and problem-solving to do. In tennis or… ## [Media I've Enjoyed](https://vincent-cheng.com/media-ive-enjoyed/) _2024-12-26 · Vincent Cheng_ obviously non-exhaustive Movies/shows Monster (Japanese movie): messes with your head. 8/10 Squid Game The Prestige: It’s so good.

Cursor is really powerful. Having never worked with selenium drivers and barely editing any lines of code, I made a pretty nice scraper in two afternoons. It just works. However, there’s a pretty significant distinction of using AI code editors that I haven’t seen explicitly… ## [Principle of Least Action](https://vincent-cheng.com/principle-of-least-action/) _2024-11-05 · Vincent Cheng_ I thought this video was really fun and wrote up some of the derivations that the video went over quickly. Introduction and Basic Principles Maupertuis’ principle of least action states that the action, defined as: $$ S\_0 = \\sum mvs $$ where $m$ is the mass, $v$ is the velocity, and $s$ is the distance, reaches a minimum along the actual path of motion. Euler later generalized this to a… ## [Weird Things in High Dimensions](https://vincent-cheng.com/weird-/) _2024-11-05 · Vincent Cheng_ Some weird stuff happens in high-dimensions. Reference 1. High Dimensional Oranges Are Almost All Peel Consider an $n$-dimensional cube of side length 1 containing a smaller $n$-dimensional cube with side length $0.8$ (“pulp”) surrounded by a $0.1$-width border (“peel”). The volume of the pulp is $0.8^n$, which rapidly approaches 0 as $n$ increases: Dimensions Pulp Volume… ## [Watch More YouTube](https://vincent-cheng.com/watch-more-youtube/) _2024-09-20 · Vincent Cheng_ Many people have written about curating a very good Twitter feed , but I have yet to see anyone talk about doing this with Youtube. I don’t know if many people do it but don’t talk about it, don’t do it, or what. I guess “subscribe to tons of accounts you enjoy, use the “Not Interested” for ones you want to avoid, and harvest” is not very deep. YouTube’s…
