Citadel fired their best quant. He rebuilt their entire algo with Claude Fable 5 in 48 hours - and he's up $430,000 trading it against them.

He didn't take a single file. He didn't need to - ten years of that logic lived in his head, and you can't raid a memory.

Wallet proof: https://t.co/JSA6VkmGuX

Here's the engine MiroFish runs - and it's rigged in his favor. Picture a Galton board: a ball dropping through eight rows of pegs, bouncing left or right at random.

One ball is chaos. Thousands of balls always fall into the same bell curve. That's the law he weaponized.

Every ball is one trade. Each row is a volatility gate - news, liquidations, order-book flow, things nobody controls.

On a fair board every gate is a 50/50 coin flip. His model tilts each one to 0.54 - four cents of edge that only shows up when fair value splits from the book.

Four cents sounds like nothing.

Compound it through eight gates, thirty-two thousand times, and the whole bell shifts right of breakeven: 71% of trades land green.

$93 of edge per trade. $430k across the distance.

Watch the win rate converge in real time - it swings between 50 and 85% for the first few dozen trades, then locks on 0.71 and never leaves.

He doesn't predict a single trade. One trade is a coin flip. Eighteen thousand is mathematics.

They thought firing him protected the edge. They just handed it a grudge.

Copy the wallet quietly out-trading a $60B fund before they connect the dots: https://t.co/vbDZyVcfT3

그런데 AI가 점점 더 똑똑해지고, 더 현명해진다면
결국 기계가 흉내 낼 수 없는 영역만 인간의 몫으로 남게 됩니다.
그리고 그 영역은 어쩌면
젊음이라는 이름의 무모함, 도전, 그리고 남들과 다른 생각일지 모릅니다.
Claude Code를 만지다가 든 생각이었습니다.

그놈의 AI...
사회 초년생들에게 당장은 버거운 시간이 될 수 있습니다.
하지만 조금만 지나면, 그들이 중심이 되는 시대가 올 겁니다.
초년생과 중견 직장인의 차이는 뭘까요?
초년생은 패기와 상상력으로 승부하고,
중견은 경험과 지식으로 무게를 더하죠.

@TeamYouTube After youtube channel is recovered, my playlists are gone and have not recovered. I had many my own playlists. After the incident almost all playlists are erased except some (three) empty playlists with no name. As I created a playlist for test, only that remains.

@hyunbinseo97 안녕하세요. 옆 부서 근무하고 있습니다. context를 설명해주시면 담당부서에 전달해드리겠습니다. 국내/해외 메세징맥락인지, latency/throughput 어느 메트릭인지요. DM주셔도 좋습니다. 감사합니다.

The future of building startups:

- MVP speed (1x per month)
- AI-accelerated
- Superniche is the new niche
- Community 1st, software 2nd
- No-code 1st, some code 2nd
- 10x more automated
- Global teams, localized products
- 95% dominated by solopreneurs and microentrepreneurs (teams less than 12)
- Pop-up digital experiences (apps that only work on certain times)
- Needs the marketing holy-trinity to hit escape velocity: 1. product/market fit, 2. content/market fit and 3. community/market fit
- Team is half robots 🤖, half humans 👨‍🦰 (cc @youneedarobot)
- Accelerated by "boring marketing" (cc @boringmarketer)
- Multiple revenue streams
- Design matters. The bar is high
- Partnered w/ creators (creators are the distribution)
- Feels like a game (levels, status, badges, in-app currency, challenges, collectibles/items)
- Purpose-driven moonshots: societal impact matters
- Productized agencies to generate cashflow (ex design agency @DispatchDesign)
- Product studios become the norm
- 99% of MVPs won't need VC

@GeekNewsBot 점점 좋아지네요 ^^. 혹시 mattermost (slack clone) 봇도 부탁드려도 될까요? 슬랙과 메세지포맷도 같거든요. 혹시나 해서 잔디/팀즈/디스코드에 웹훅 추가해봤는데 안되더라고요.. 메세지 규격이나 호스트 체크를 하셔서 그럴까요? 수고에 감사드립니다~

ERR_print_errors()에서 자꾸 죽고 있어서 이게 왜이러나 했더니만 OpenSSL 엔진이 친절하게도 실패함수명을 댕글링 포인터를 반환했다. 많은 시간이 날아갔다.

When an dynamic OpenSSL engine loading fails, we can get SEGV if it calls ERR_put_error() kindly. Oh my hours...

I am very concerned that Apple Silicon will have the same sort of concurrency concerns that their PowerPC systems used to have due to the relaxed memory model of ARM relative to X86. There's a ton of desktop software written assuming TSO.

So many bugs; so many missing fences.
