Liked on XI made a mistake. When Jack and I decided to organize this $100K Hackathon, my biggest concern was cheating. Unlike a regular hackathon, everyone participates from home. And because the winner is whoever makes the most PROFIT (not revenue), there are so many ways to manipulate the numbers. So I added a $99 entry fee. One thing I’ve learned from building businesses is that people tend to be more committed when they pay for something. I thought it would filter out spam, attract serious builders, and make the competition fairer for everyone. But I completely missed the other side. 3 years ago, I was a living with my apps. Today, I’m financially free. My life changed so much that somewhere along the way, I lost perspective on what $99 means to someone else. For someone in India, someone struggling to pay their bills, or someone trying to make their first dollar online, $99 can be a lot of money. And those are exactly the people I want to help! I’ve spent years sharing what I’ve learned, reviewing random people’s landing pages, and organizing free meetups around the world. Not because there’s money to make, but because I genuinely love seeing people build things and succeed. And somehow, I was so focused on keeping cheaters out that I didn’t realize I was also keeping genuine builders out. That’s my mistake. So I’ve decided to make the $100K Hackathon completely FREE :) Everyone who already paid got a full refund. I’m still worried about cheating. That problem hasn’t disappeared, and Jack and I will have to figure out better ways to verify profits and keep the leaderboard fair. But that’s our problem to solve. Thank you to everyone who shared their thoughts. Sometimes you need people to remind you of things you’ve forgotten. I genuinely hope this hackathon changes someone’s life. ❤️Liked on XIt’s time to bring back Cafe CursorPosted on Xyo @pendev i can't live share edit a .pen file? it's the most needed featurePosted on XI'm coining a word "Agentsplaining" Agents condescendingly assuming the user don't know fuck and repeating the obviousReplied on X@jayhxmo @raycast Hard to explain.

Challenge them. - What can be deleted entirely? - What can be simplified now that unnecessary pieces are gone? Then make the changes. Prefer deleting over simplifying, simplifying over optimizing, and optimizing over automating. This product is being used by thousands of customers, do not cut any corners." This prompt is one I run often and leads to the best results.Replied on X@akshayadinesh19 @bot can we please BYOM for botsLiked on XTo be fair, the Chinese models have a much lower refusal rateLiked on XF*CK IT, im creating a library of AI slop indicators. my feed is full of taste larpers. stay tuned https://t.co/5Muv8nQRm3Liked on XJENSEN! THATS NOT WHAT WE MEANT BY CHINESE MODELS!!!!!!!Liked on Xmy parents had to declare bankruptcy when I was a kid, so they had every reason to pressure me towards a more stable career path instead, they were so patient with me, even as i failed startup after startup for years so getting to tell my mom that everything turned out okay was a really special moment :) for those who can't read Korean, her first message roughly translates to: "Really!!! Congratulations my son. So much :') Thank you God!" i know I've been posting about my exit for like a week now, but it really is a big deal for me and my family! i'll share more about how this all happened and some tactical advice later this week, but for now i'm just riding out all the emotions to quote my mom, thank you God!!!!Liked on X@thefarmers_Dog it stands for Egg GzampleLiked on X🦍 Introducing Memorilla: memory as a modality for LLMs Memorilla turns everything a frozen LLM needs to remember into just 16 memory embeddings ⚡ It uses up to 4,212× fewer tokens and is 27× faster than full context inference while more accurate 🎯 Pushes the Pareto frontier over RAG and agentic memory in personalization, long-document and knowledge QA A thread 🧵:Liked on XThere's a huge product opportunity downstream of Tailscale etc too. At @tldraw we've started designing for "high trust networks" and it's been a beautiful thing. 1. Features that would be a nightmare on the internet are okay on my computer and mostly okay on private networks. Websites that execute user-generated scripts, control production systems, allow for users to send desktop notifications, spend tokens, or directly prompt my agent. Crazy stuff that would only make sense if everyone was in a committed polycule. 2. When everyone on the server can be trusted to have _external_ reasons for good behavior (eg keeping their job, or maintaining friends, family, church, mafia org), the software can be designed in a default social way. Most apps default to isolation, low horizontal visibility, highly restricted collaboration. Makes sense if the social contracts are inside of the app, but if you can trust that they live outside of the app then you can get wild. Example being small group chat names as an emergent comedy phenomenon because anyone in the group can change the name. 3. This can work for commercial products, too, not just internal stuff. Security matters more than ever but the way we've seen that manifest is that more companies are more confident in their own solutions than anything we could provide, to the point where owning data and access is a better value proposition than having it managed. Always has been true for big companies but now even small companies can get a good secure network set up pretty easily, and the hooks we need to build are easy enough. tldraw offline got us started down this road (and shout out to @pendev for first introducing me to the idea of desktop + mcp). We've been bringing that product to private networks and it's been exciting to see how much we can get away with. Keep an eye outReplied on X@saradu birds eye viewLiked on XApplications close in 2 days!! If you have a cool bio idea, and $5-10k will go a long way for you, please apply!!! https://t.co/NCvmrNC53cLiked on XWe've been early adopters of Rust since 2018 and a lot of our infra, voice tech, and even some of the current client is already Rust, the holy grail was getting the whole client there. That means Electron goes away, and so does React Native, mobile keeps native UI but shares app code with desktop via Rust. We hope to get it into testing with users soon™. (And it's not Tauri, it's GPUI, so good guess everyone.) Alright, back to staring at the WoW Forever login screen.Reposted on XOh boy. https://t.co/X7SSskGuGvLiked on XRIP .si domain squatters

I build cognitive infrastructure for science: epistemic systems that function as a for human researchers. This is not AGI. It is capable enough to measurably expand human scientific throughput while preserving human control over claims, evidence, and verification.

The objective is "unrotting researchers' brains," or epistemic sovereignty under AI: keeping knowledge networks reliable when synthetic content is cheap and ubiquitous. I have written about knowledge rot and verification collapse, in which unverified AI output degrades shared truth. This aligns with Anthropic's focus on AI that remains under human direction and in accordance with human values. I want to build epistemic infrastructure for AI that increases truthfulness, auditability, and trust instead of eroding them.

My fit is practical. I operate across research, infrastructure engineering, and system design. I build systems that translate theory into durable tools, evaluation, and operations. I aim to be a Science Medici, accelerating scientific progress by enabling other researchers with high-leverage platforms.

I bring experience in AIOps and federated learning, plus a safety-first approach to deployment. I want to contribute to co-scientist systems with rigorous verification, provenance, uncertainty tracking, and human-in-the-loop oversight at scale.

Please tell us briefly about an area of technical AI safety work you're currently excited about, and why.

Building AI epistemic infrastructure that makes large language models more reliable and more truthful. Implementing systems that monitor, audit, and augment a model's knowledge so that deployed models resist knowledge decay and failure modes such as model collapse.

The risk is known: training or fine-tuning on low-quality, synthetic, or poorly filtered data can degrade model performance and distort learned distributions, weakening factual reliability and value alignment. The response is engineering, not slogans.

My approach combines retrieval and operations. Use retrieval-augmented generation so that outputs are grounded in trusted corpora with provenance, citations, and adversarially robust retrieval. Add continuous AI-Ops monitoring that treats models as production-critical systems: drift detection, calibration checks, red-team regressions, automated eval suites, anomaly detection on outputs, and human-in-the-loop feedback loops tied to measurable quality gates.

This is safety work with concrete artifacts. It creates verifiability, transparency, and long-horizon resilience. It prevents small errors from compounding into systemic misinformation by detecting degradation early and enforcing corrective interventions.

Relevant AI safety background

My background spans AI research and production engineering, with a consistent focus on robustness, trustworthiness, and alignment with human constraints.

At Lunit, a medical AI company, I led engineering work on an AI-Ops platform (INCL) to support the reliable deployment of models in high-stakes clinical settings. That work imposed rigor on monitoring, rollback, evaluation, and cost controls, making safety and operational discipline non-negotiable.

At , I worked on the Experimentation Platform and saw how large language models are managed and evaluated for quality in a product environment.

On the research side, I collaborated with Prof. Jose-Luis Ambite at USC ISI on vertical federated learning for privacy-preserving data integration. The goal was to enable cross-institution learning without centralizing sensitive data, aligning model development with privacy requirements by design.

I also maintain a personal knowledge base, , where I publish analyses on knowledge rot, epistemic scaffolding, and self-amplifying failure modes in AI-mediated knowledge systems. That includes an "encyclopedia meltdown" scenario in which AI-generated content recursively degrades a knowledge base, reinforcing my focus on safeguards, verification, and provenance.
