New comment by Alex3917 in "Demand for autism care is soaring"

Alex3917 — Sun, 05 Apr 2026 01:05:40 +0000

There is a huge amount of overlap between the genes associated with schizophrenia and the genes associated with autism. This is part of what makes it tricky to diagnose yourself, because anyone who has the genes for schizophrenia is also going to have a lot of autism symptoms even if they don't have autism.

Not to be confused with Google’s existing product called Wiz.

Having worked at both greenfield startups and unicorns, I've found that virtually every problem I've encountered at the unicorn startups was caused by folks being incompetent at the greenfield level. Maybe when you get to the scale of Google things are different, but it's certainly possible to build a business big enough to retire off that doesn't require any more technical knowledge than what you'd learn at a two-person pre-PMF startup.

For both Amazon and Nvidia, their marginal costs are probably much lower than their fixed costs.

They bought both Deja and Neotonic.

I mean the I would really only include the code for things like:

- Fetching email messages

- Parsing email headers

- Mime parsing

- Converting the text of email bodies into UTF-8

- Threading messages

- Eliding reply text

Given that the official story is that pb made the first version of Gmail in a day, does anyone actually believe that he wrote the code for any of those things in a day? If you honestly believe that I have a bridge to sell you.

Wait till you learn that the source code in Chrome also predates the existence of Google.

He wasn't sitting there writing binary code and implementing all 7 layers of the OSI stack by hand, he was was gluing together pre-existing components. And the pre-existing components he had access to include two major email startups acquired by Google in 2001 and 2003, which were founded in 1995 and 1997 respectively. (Although he does have at least two patents for features and algorithms he co-invented while making Gmail.)

> You guys cloned a whole suite of products in a short period of time that cost millions of dollars.

At the risk of stating the obvious, the functionality isn't actually cloned, only the UI. The actual code powering Gmail probably dates back to the late 80s or early 90s and has had several hundred thousands of hours of work put into it. This is just a webpage that looks kind of similar.

I point this out only because I've seen people saying that software businesses don't have moats anymore because of this, which is taking away a completely false lesson.

Sure, if you could use VBA to read a patient's current complaint, vitals, and medical history, look up all the relevant research on Google Scholar, and then output a recommended course of treatment.

This is the key issue. There is zero doubt whatsoever that flossing is essential, and the fact that the empirical evidence is equivocal shows the limitations of science to prove even the most obvious things.

> What’s stopping a similar crisis that 23andMe customers faced where their genetic data along with their identifying information getting sold to the highest bidder if you ever become insolvent?

Nucleus employee here. Nucleus is a medical provider that is providing a medical service and is regulated by medical laws, which extend even through bankruptcy or acquisition. Whereas 23andMe was essentially an entertainment company and was regulated as such, which is what enabled that unfortunate situation to occur.

New comment by Alex3917 in "Why do LLMs freak out over the seahorse emoji?"

> But then at the end it added a "Fun fact" that unicode actually does have a seahorse emoji, and proceeded to melt down in the usual way.

To be fair, most developers I’ve worked with will have a meltdown if I try to start a conversation about Unicode.

E.g. if during a job interview the interviewer asks you to check if a string is a palindrome, try explaining why that isn’t technically possible in Python (at least during an interview) without using a third-party library.

> It’s still the best measure we have, though you should obviously know that LDL measured while on statins is lower than it would be normally.

I'm not a doctor, but doesn't LDL basically just prevent the body from healing damage to the epithelium, which comes from things like high blood pressure and inflammation? Unless my understanding is wildly off base, it doesn't really make sense that a thing that merely slows down the healing process would be more predictive than the things causing the damage in the first place, given that if you aren't accumulating significant damage then your levels of cholesterol are somewhat moot.
