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.

Might resub Raycast pro just cuz of thisReplied on X@ishuagra02 I saw a theory that F5.2 is a post train of 5.1, but O5.5 is a distillation of F5.5(unreleased new pretrain) and thats why O5.5 > F5.2Liked on X@anaclumos don't know what is actually improved 👀Posted on Xam i the only one underimpressed with 5.2 fableReplied on X@bvvst great minds think alike https://t.co/YRFWhb1mcOLiked on XClaude Fable 5.2 is out and it's the perfect time to run this god-level prompt on your codebase: "I want you to audit our codebase, is anything here unnecessary, overly complicated in our current setup, or based on weak assumptions? 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
공기 청정 비행선

공기 청정 비행선

Warning

Over a year old. May be outdated

원인이 뭐든, 누가 원인을 제공했든, 그런 것을 다 떠나서 그냥 고치면 좋겠다.

서울의 공기는 최악이다.

그냥 공기를 정화하는 비행선을 단체로 다같이 띄워 올려서 공기 정화를 시도해보면 어떨까.

그냥 하루 종일 대기 중에 떠다니며 미세먼지를 거르는 것이다.

Can we build a giant blimp to clean polluted air?

충분히 가능하다. 자동차에 달린 것 같은 촉매 변환기를 아주 크게 만들어서 하늘에 띄우면 된다. 근데 콜롬비아 대학의 환경 과학자 피터 아이젠버거는 이게 또 다른 대기 오염을 부를 거라고 말한다. 의미 있는 차이를 만들려면 이런 저공비행 청소기가 하늘을 가득 메울 만큼 많이 필요하기 때문이다.

이 공중 공기 청정 스테이션은 비행선에 거대한 집진 후드를 바깥으로 달고, 그 안에 여러 종류의 공기 청정 장치를 담은 확장 하우징을 단 구조다. 집진 후드가 오염된 주변 공기를 흡입 시스템으로 끌어들이고, 이 공기는 후드와 이어진 기내 공기 청정 장치로 흘러간다. 스테이션 안의 센서가 들어오는 공기를 분석해서 그 지역 대기에서 어떤 오염 물질을 걸러야 할지 정한다. 그러면 자동 제어 시스템이 배관의 자동 밸브를 움직여서, 들어온 공기를 센서가 잡아낸 오염 물질을 제일 잘 걸러 내는 장치로 보낸다. 습식 스크러버, 여과기, 사이클론 스프레이 스크러버 같은 장치를 골고루 갖추고 있어서 온갖 오염 물질을 처리할 수 있다. 걸러진 공기는 배기 시스템이 다시 대기로 내보낸다. 이때 방향을 바꿀 수 있는 이동식 배기 덕트를 쓰기 때문에, 나가는 공기 흐름을 원하는 쪽으로 보내서 비행선의 보조 추진력으로도 쓸 수 있다.

이 실용신안은 스스로 전기를 만드는 공기 정화 부유 비행선에 관한 것이다. 비행선 본체는 연결체로 지면이나 옥상에 묶여 있고, 본체 양 끝에는 공기 흡입구와 배출구가 하나씩 있다. 흡입구와 배출구 사이의 본체 안쪽은 나팔 모양의 정화실로 되어 있는데, 이 정화실의 단면적은 흡입구에서 배출구 쪽으로 갈수록 점점 줄어든다. 흡입구 가까운 쪽에는 정전기로 먼지를 붙잡는 공기 정화 장치가, 배출구 가까운 쪽에는 바람으로 전기를 만들면서 공기 흐름도 잡아 주는 날개가 달려 있다.
