Entrepreneur and founder of Blueprint. Publishes a detailed, freely available longevity protocol documenting the food, supplements, devices and measurements he uses on himself.
We were surprised yesterday to learn that Kate was being asked to fill her vagina with ultrasound gel. The MRI was to characterize her endometriosis. A disease where endometrial tissue develops outside the uterus and grows. It's a gnarly and painful disease with serious health complications. It affects 1 in 10 women and currently takes on average 6.6 years to diagnose. We hustled and diagnosed Kate's endometriosis in 42 days via four speciality different tests (blood, MRI, salvia, transvaginal ultrasound). The fastest and most comprehensive ever, I think. We are doing this MRI because we have… Quoting @_katetolo I had to fill my vagina with ultrasound gel yesterday for an MRI... I had no idea this was a protocol for measuring endometriosis! how cool It's a technique called vaginal opacification... the vagina is normally a collapsed space, and on an MRI, collapsed walls are hard to tell apart from the tissu… Related
Writer on habits and decision-making; author of Atomic Habits and the 3-2-1 newsletter, and publisher of long-running book recommendation lists.
When choosing a new habit many people seem to ask themselves, "What can I do on my best days?" The trick is to ask, "What can I stick to even on my worst days?" Start small. Master the art of showing up. Scale up when you have the time, energy, and interest. energy Related

I don't trust anyone's AI risk assessment. I don't think we know what awaits us. Given that, I'm choosing to be optimistic, betting an existence more extraordinary than we can imagine sits on the other side and it's worth fighting for. Related

It was painful to see so many users being priced out of AI coding for a while. But now it’s free to build again! Quoting @Kyrannio Replit introducing free mode is the best thing they have ever done, but even if you are not using free mode, you are really getting a screaming great deal to develop with at present. Development costs everywhere are going to go up as the newer models come out, but I genuinely can't recommend Replit… Related

want to hear an interesting strategy story between meta and apple? 10 years ago i was at meta, and worked on a lot of product features that had to ship to iOS, and they all had to go through a painful apple review where anything could get cut apple back then developed a clear strategy where they used “privacy” as the angle to gain user trust and win against competition a clear example was the “ask app not to track” dialog which controls ads targeting - they made every 3p app go through that scary dialog which heavily implies to the user that they should obviously click “do not track” you migh… Related

It’s a strange and painful thing to step away from a place that holds so much of your work, friendships and history. The people at id have done a great job moving that legacy forward. DOOM, Quake, and Wolfenstein are not easy names to carry on, especially in today’s industry. The last few games showed real care, skill and respect for what those worlds mean to people.

Uh, care a little bit less about your pre-existing interests because they're kind of arbitrary right now. and care a little bit more about whether like the person teaching it is a good educator and someone you resonate with.

I believe this is the right answer. We're often being manipulated by politicians, by corporate leaders to make a choice from two suboptimal options.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
