I went through the same evolution where I now understand it like brushing your teeth, exactly as you said. In fact, it’s even more important than brushing your teeth. I don’t think society teaches it this way but they should.
I've been making a Rust-based XML parser that can be used on its own, or as a drop-in replacement for libxml2 at the C ABI level. Basically, it's not only 2x faster than libxml2, but being written in Rust eliminates a lot of cybersecurity risk. Roughly 70% of CVEs come from memory-safety bugs, a whole class that Rust rules out at compile time.

Instead of going open source, consider selling licenses with Supported Source (
https://supso.org/). I made this for the maintainer problem: it's easy to burnout when companies are constantly asking for new features or fixes, while not paying you anything. Why should you work for free so these companies can make more profits? When they start paying you, you're a lot happier about it.

Seems similar to open source bounties, which have been tried in the past and never succeeded.
We've seen something like 20+ years of different attempts of voluntary donations to fund open source, and it never worked. Companies barely fund anything voluntarily.
I'm taking the opposite approach with Supported Source (https://supso.org/) which is this: actually force companies to pay to use the project. Sell commercial licenses. Make it mandatory to using your software commercially. This approach works much, much better than voluntary donations.

Open source funding is broken. That's why I'm making Supported Source (
https://supso.org/).

There’s a lot of umbrella diagnoses that would benefit from more specific diagnostics first. What we call Alzheimer’s is probably actually caused by number of different causes depending on the person. This is true of a lot of things in medicine that get grouped together. That’s why testing a drug in mouse models with all the same characteristics sometimes works but fails to translate into humans who have more variety amongst each other.
The same is true of many diagnoses like pneumonia, cancer, alopecia, essential tremor: there’s multiple different groups that would benefit from different things, and if we had better ways to identify the groups, we’d give them what works for them instead of wasting their time with the wrong treatment. As an example, antibiotics won’t work for viral pneumonia and in addition to wasting the patient’s time, actually harm your microbiome. If you had a perfect way to know which is which, you’d always get the right treatment.
Precision medicine takes this even further.
hs-CRP is well known as a useful biomarker and it is cheap to test too. If you look at page 13 of the GrimAge 2 paper, you'll see CRP is one of the factors most negatively correlated with their aging clock, in fact basically as strong of a negative impact as smoking.

It's definitely not some marketing fad.
I would like to know how regular sunlight compares to the combination of vitamin D supplementation and red light therapy. If you do both of those, is that equivalent or better since it doesn't have any damaging effects of the sun?
What do you think about the Nobel prize in physics going for neural networks last year? What combinations of AI + physics do you think will be most impactful and could potentially get a Nobel prize?

"Mayo’s LLM split the summaries it generated into individual facts, then matched those back to source documents. A second LLM then scored how well the facts aligned with those sources, specifically if there was a causal relationship between the two."
It doesn't sound novel from the article. I built something similar over a year ago. Here's a related example from Langchain "How to get a RAG application to add citations" https://python.langchain.com/docs/how_to/qa_citations/
That would not have solved the problem in this fire since wind speed was so high. The videos showed embers traveling far and fast. Having a 10 foot fire break would not have prevented the spread. One thing to look into is how the fire started and if the electrical equipment can be made safer, like being underground in some places.
I made something like this to let people explore the lore of my game. It has an AI act like a dungeon master as you play through a story. You can try it for free at:
https://orbsccg.com/adventuresThe main game is a strategic collectible card game, but the “adventure mode” is just for fun AI-powered stories.
Even Waymo has external investors. It’s not all funded by Alphabet.
I don’t know why this is downvoted. The lack of profit motive is a big reason that nutrition and supplements aren’t as well studied through rigorous trials as drug therapies. The ones that are run are funded by grants. Rather than just “more funding” I think there needs to be more systemic ways at reducing the cost of clinical trials or using alternate methods of getting high quality scientific data for answering these questions.
For example, there is a good trial running now on ketogenic diet in glioblastoma patients, NCT05708352, I think with a NIH grant and maybe the NCI as well. Here is a video about it: https://www.youtube.com/watch?v=W31kR0MzyRA
Food and nutrition is a big business though.
IEEE Spectrum used to be good. I don't know whether it still is. Does anyone know?
Peleton is not a monopoly. Anyone can make an exercise bike. Anyone can offer an online class. I own an exercise bike made by a different company.
I mean it is pretty common to set c=1 though.
There are many cases where you're getting blood drawn already and if adding another test onto that is inexpensive, that's a pretty convenient add-on. That's useful for many reasons.
I was also wondering how it performed compared to a stool test, so I looked it up, and found "While the blood test caught 83% of the cancers found by colonoscopy, it missed 17%. That’s on par with stool-based tests."
It's called a multi-cancer early detection test and they already exist.
There's still value in specific tests, though.
In my experience as a Stanford alum, this is not true. The professors interact with undergrad students all the time.
If you’re seriously considering lying to the CTO you should instead just get a different job at a different company. That’s a really bad working environment if you think lying is acceptable or something to be proud of.
It was probably mentioned in the textbook and you just forgot. I just checked my textbook and it’s one of the first things they say when introducing mitochondria and chloroplasts.
The CEO said on Twitter: "In fact, we built Confidential Cloud in such a way that only you can decrypt your data. Your employer, we as software providers, and the government cannot decrypt your data without your permission, even with a subpoena to do so."
So I think a monthly subscription is the business model, not ads.
The circulation subscriptions were a substantial part of their revenue, however you're right that ads were even larger. I don't think it's fair to say few people ever paid for it though. Subscriptions were important too.
