(https://x.com/charlie_meyer_/status/1995718629099241700)
- Most recent X post during his Cognition tenure reads simply: "saving the world!!!"; no detailed public post about his Cognition work was found in his X timeline. (https://x.com/charlie_meyer_/status/2114744383614734406)
- Endorsed a community program on X: "best community I've been a part of & I can't recommend more for you to apply!". (https://x.com/charlie_meyer_/status/2057536529455857862)
- Announced the self-driving couch project on X: "got pulled over on my self-driving couch". (https://x.com/charlie_meyer_/status/2053548680636944635)
- Built a self-driving couch from a $5 Goodwill couch with a drivable frame, vision, depth perception, and navigation Quote: "We built a self-driving couch! This was the culmination of a semester of on-and-off work, taking a $5 couch from Goodwill, building a drivable frame around it, and wiring up vision, depth perception, and navigation into it." (https://charliemeyer.xyz/posts/self-driving-couch)
- Streamed data from a custom iPhone app (GPS, LiDAR, cameras) and motor IMU telemetry into a Jetson Orin Nano running ROS 2 Quote: "In short, we stream data from a custom iPhone app (GPS, LiDAR, cameras) along with other telemetry data from our motors (IMU data) into a Jetson Orin Nano, which runs ROS 2." (https://charliemeyer.xyz/posts/self-driving-couch)

(https://charliemeyer.xyz/posts/self-driving-couch)
- Got pulled over while driving the couch; received a warning Quote: "Also, I got pulled over (which was my goal in the first place!).

- Learned that a hard, out-of-depth project motivates smart people to join more than an easy or well-defined task Quote: "Working on a hard (and in college, stupid/edgy) project is the best way to motivate smart people to work on something with you. Paradoxically, pitching a task that is way out of your depth is more likely to get takers than something that's easy or is well-defined." (https://charliemeyer.xyz/posts/self-driving-couch)
- Observed that although seven people were in a group chat, effectively two people contributed to the project Quote: "While there were seven people in a group chat to coordinate work, effectively two people contributed to this project." (https://charliemeyer.xyz/posts/self-driving-couch)
- Learned that adding contributors has coordination overhead and doesn't necessarily add proportional value Quote: "Adding one extra contributor to a module/project doesn't necessarily correlate to adding one extra contributor's worth of value due to coordination overhead." (https://charliemeyer.xyz/posts/self-driving-couch)
- Expressed respect for people who build physical things, noting tangible costs and inability to have Claude control a drill Quote: "I have an incredible amount of respect for people who build physical things. Unlike software, the costs are much more tangible (money, part shipping time), and we aren't (yet) able to have Claude control a drill." (https://charliemeyer.xyz/posts/self-driving-couch)
- Learned that higher-quality messaging and node organization makes backtesting captured bags and debugging easier Quote: "Moreover, the higher-quality your messaging and node organization is, the easier it is to backtest captured bags of a run, debug issues, and iterate." (https://charliemeyer.xyz/posts/self-driving-couch)
- Posted product feedback while working on PR-review agents (after his Vercel Agent internship): "@github need \"copy comment as markdown\" for all these PR review agents please! or deep links into IDEs". (https://x.com/charlie_meyer_/status/1994818422564397148)
- Built a security research report/hack of Series.so, discovering an unauthenticated backend API and a user data access vulnerability Quote: "I did this out of curiosity and my passion for AI safety, and I'm sharing my findings to help the team improve their security." (https://charliemeyer.xyz/posts/security-in-the-vibe-coding-age-hacking-series-so)
- Discovered Series.so's unauthenticated SwaggerUI backend API by tracing network requests and visiting /docs Quote: "Then, I guessed that they were using SwaggerUI, went to `/docs`, and this took me to the full SwaggerUI docs for their completely unauthenticated backend. This vulnerability required no hacking skills, just some curiosity and a bit of poking around!" (https://charliemeyer.xyz/posts/security-in-the-vibe-coding-age-hacking-series-so)
- Discovered a second vulnerability allowing any user to query any user's profile by user_id after the first was patched Quote: "I discovered the second vulnerability after they had patched the first vulnerability" (https://charliemeyer.xyz/posts/security-in-the-vibe-coding-age-hacking-series-so)

- Had not received a bug bounty from the Series team at time of writing Quote: "At the time of writing, I have yet to receive a bug bounty from the Series team." (https://charliemeyer.xyz/posts/security-in-the-vibe-coding-age-hacking-series-so)
- States motivation was pure curiosity and care for AI safety and application safety Quote: "Finally, I want to clarify _why_ I did this—pure curiosity. I care deeply about AI safety and application safety, and poking around websites is just a fun hobby of mine." (https://charliemeyer.xyz/posts/security-in-the-vibe-coding-age-hacking-series-so)
