HonestLaunch: a claim-auditor I built at the I/O hackathon. It reads an AI launch post, grounds each headline claim, and rewrites the overstated ones with receipts.
Claude Opus 4.8 was mostly solid. The "kickoff-to-merge codebase migrations" line was the stretch: the flagship Bun port relied on a hand-written 300-rule guide, landed at 99.8% tests, and shipped UB in safe Rust.

@BradStanfieldMD Super helpful!!
I was apprehensive about suggesting Rapa to my mother, but now I'm confident in not recommending it yet

Our Rapamycin & Exercise clinical trial has just been published!
The topline result?
Rapamycin didn't help. Instead, it may have made things worse.
Here's what we found 🧵

Hired an e-girl to promote creatine

The era of fake e-girl influencers has started

@Holmes1618 @BradStanfieldMD 100%. Reviewers should be expected to turn around the feedback 10x faster now that we have access to such intelligent LLMs.

@BradStanfieldMD Why does the rapamycin study result held back by peer review so long? We are in the age of AI, wasting one week is wasting one year.

@vitaloik4781 @bryan_johnson Yep like 6 months apart. Company is BodySpec
English

@RupertDodkins @bryan_johnson But five years of a healthy lifestyle isn't enough. What do the two numbers in the visceral fat report mean? Two measurements, several months apart?
English

@vitaloik4781 @bryan_johnson Low visceral fat is a lot more important than over all body fat for longevity.
He does have a better six pack than me tho 🤷♂️
English

@RupertDodkins @bryan_johnson Younger) This method of measuring visceral fat is very inaccurate; an MRI is needed. Brian's body fat percentage is around 10%, significantly less than yours. He also said he had a poor lifestyle for many years. It's constantly improving.

@siimland Just curious, what’s the cost of a blood panel that has 183 biomarkers?
English

I analyzed Bryan Johnson’s biomarkers… and he doesn’t have the best in the world.
I analyzed 65 of the markers he’s published:
-44 of them I have better results
-9 of them, Bryan has better results
-12 of them are equal
In this thread, I’m sharing the markers and comparing them⬇️⬇️
P.S.
1. I’m not claiming I'm the healthiest person alive or to have the world’s best biomarkers—but I do have factually better biomarkers than Bryan.
There are dozens of people who have better biomarkers than Bryan and me out there.
2. This isn’t about “dunking” on Bryan. Bryan always asks for people to challenge his results and prove if someone has better markers, so here I am.
3. I disagree that you can base someone's health solely on biomarkers because biomarkers can be gamed with pharmaceuticals, etc. But I'm just playing Bryan's own game here.
4. Age is a moot point. Bryan says he has the best biomarkers of anyone in the world. If chronological age mattered, the “healthiest person” would always be an 18–20-year-old.
I’m 30, and my biomarkers are better than his, so his claim doesn’t hold. He could argue he’s the healthiest 47-year-old, but not the healthiest overall.
Now that this is out of the way, let's go through all the biomarkers.

hey @alexalbert__ @_catwu Please help - trying to onboard one of my engineers to Claude Code and it randomly goes to "offline", he's able to call the Claude API with the same API key/same machine/same network connection without issue.

@PiyushNarwani Damn no more X time for me today, only coding 🤣

@j4ded @dr_cintas This was the one feature cursor did better. Now that windsurf has it, its a no-brainer which to use
