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

Warning

Over a year old. May be outdated

Work Research

오늘은 반드시 Scheduler를 잡아내자.

에 확인한 2가지 스케줄러를 확인한다.

Web Worker Thread에서 나타난 AnimationFrame.ts은 requestAnimationFrame에 관련된 것으로 보이고 Data Transfer과는 무관해보인다 (불확실).

즉 자세하게 봐야하는 것은 WorkerDOMConfiguration에 나온 다음 부분이다.

ts
export interface WorkerDOMConfiguration {
  // ...
  // ---- Optional, with defaults
  // Schedules mutation phase.
  mutationPump: MutationPumpFunction;

  // ---- Optional Overrides
  // Schedules long task.
  longTask?: LongTaskFunction;
  // ...
}

LongTaskFunction의 차이는 Promise가 있다는 것이다.

MutationPumpFunction의 타입 정의는 다음과 같다.

ts
export type MutationPumpFunction = (flush: Function, phase: Phase) => void;

flush는 무언가 뒷정리를 하는 함수처럼 보인다 (불확실).

Phase는 다음과 같다.

ts
export const enum Phase {
  Initializing = 0,
  Hydrating = 1,
  Mutating = 2,
}

InboundWorkerDOMConfiguration과 WorkerDOMConfiguration의 차이는 무엇인가?

우선 다음과 같은 변환 함수가 있다.

InboundWorkerDOMConfiguration에는 없는 기본값을 설정해준다.

ts
export function normalizeConfiguration(
  config: InboundWorkerDOMConfiguration,
): WorkerDOMConfiguration {
  return Object.assign(
    {},
    {
      mutationPump: requestAnimationFrame.bind(null),
      executorsAllowed: DefaultAllowedMutations,
    },
    config,
  );
}

InboundWorkerDOMConfiguration 그리고 normalizeConfiguration이 Main Thread install.ts에만 사용되는 것으로 보아 최초 설치 시에만 InboundWorkerDOMConfiguration을 사용하는 것 같다.

도대체 어떤 방식으로 스케줄러가 동작하는지 아직 이해가 되지 않는다.

아예 스케줄러가 예상했던 동기적인 타이머가 있는 것이 아닌 것 같다 (불확실).

requestAnimationFrame에 의해 동작하는 것 같다 (불확실).

이 가정이 맞다면 requestAnimationFrame이 어떤 식으로 동작하는지 확인해야 한다.

Tim

Tim과 2시간 가량 이야기한 결과는 다음과 같다.

  • (불확실)
  • Web Worker Thread의 MutationTransfer.ts에 transferSync 레이어를 만든다.
  • TransferrableKeys에 Sync 여부를 확인하는 키를 추가한다.
  • 동기적인 연산이 필요할 경우
    • Web Worker Thread transferSync에서 를 하나 할당한다
    • TransferrableKeys를 통해 확인한다
    • Main Thread에서 Atomic Wait를 건다
    • Main Thread의 해당 프로세서에서 작업을 처리한다
    • 받은 에 데이터를 채운다
    • Web Worker Thread에 Atomic Notify를 한다

(불확실) Message 형식은 새로 만들어야 할 것 같고 Processor는 재활용할 수 있을 것 같다.
