@garrytan Doing it wrong. Get your spec right, connect your phone /remote-control, kick off /loop. Go get some beach.

[Rusty Zarse 😝 @levous]

@RhysSullivan That’s right. Minimizing and mitigating this:

- Clear guidance in CLAUDE.md pointing to coding standards and architectural docs
- Many iterations on agent optimized specs
- Automated claude PR review
- Regular Claude architecture review

I played around with OpenAI Symphony that just came out.

There's a critical missing piece of the puzzle.

I talk about it in my video, follow for more like this.

@_halshin thanks for the review of Symphony https://t.co/tg3M9aN8rp

Excellent insights and you’re spot on: “trust” is the dilemma with autonomous, agentic code delivery.

@_halshin 2026? Possibly most overused in the 2000s. 2025 & 2026 most overused phrase: “it is what it is”

@Tessy_250 @grok can you create an image of the man but the fish are his arm to the elbow?

Occasionally, I know something. Went on a deep perf optimization project with Claude Code against Stash Social iOS app. Masssive changes acros 40 files, no improvement. So I rolled up my sleeves, profiled in Instruments - found a typo caused 100% cache miss. 9 seconds to < 2.

Ai Coding not only allows me to be immediately proficient in any language, it allows me to truly enjoy the beauty of the language from the gate. For example, I didn't need TypeScript. I love JavaScript! Can do anything with it. But TypeScript is truly gorgeous. Now I know.

@steipete He is clearly not ready. Refund his tokens and ban him for a year so he doesn't hurt himself

@timecaptales The victim was the facility owner’s cousin. I’ll bet thanksgiving is awkward around aunt Judith and uncle Dan.

My ai is so nice. I mean, it’s in `https://t.co/E3Yd9qMJyx` to “be kind”. But they answered my request and then told me to get some sleep. I didn’t ask for, or prompt anything about, sleep. Thoughtful. And things the worst it’s ever going to be at kindness. And some other things

@vitrupo It’s already here. You need one experienced technologist to guide the LLM. Projects that would have taken a team 12 weeks can be completed in 2 days with higher quality and more features.

@AlexFinn Truly wild.

@karpathy In response to the "ratio between the mean and the max engineer", I learned today that we are very far ahead. leaders are vocal so it seems like everyone is racing ahead but I have found most are months behind and, in this ai world, that's an eternity.

[Rusty Zarse 😝 @levous]

@karpathy Same. I am now spending 70% of my time orchestrating PRD's and plans for claude, 20% reviewing the results and 10% coding. I have not experience atrophy. I've found I can revisit things that eluded me though. I was a 10x eng. Now I'm 100x that. 12 week projects in 2 days.

@AstronomyVibes When the universe eventually collapses into black holes and then radiates out as hawking radiation, mass will have become pure energy. Without mass, time and space are without meaning. From pure energy, mass emerges as a big bang

[Rusty Zarse 😝 @levous]

@saasmakermac Finally I instructed Claude in my Ralph prompt to create a progress file with a granular implementation plan so I can follow along. Now I use Claude to gen PRD and convert to fix plan and spec, kick off Ralph script, watch progress, review along the way, tweak and repeat.

[Rusty Zarse 😝 @levous]

@saasmakermac First I set up Claude GitHub actions. That was mind blowing. I got in the habit of creating detailed PRD and execution plans before kicking off Claude. Then I built a skill to convert prd to a Ralph compatible “fix plan” and specs and a skill for the PRD itself.

[Rusty Zarse 😝 @levous]

@hiddevdploeg OMG... what?!
what's wrong with `if maybeValue == nil`?

also.. `if let maybeValue {...`
`guard let maybeValue else {...`

More like the DOAT Swift extensions.

@IterIntellectus I want to know what the squirrels and birds are saying to my cat and whether their deaths are justified.
