Yes, that, accuracy, speed, and single computer-use.

I find those to be the limiting factors to speed.

I have extensive rules, I do extensive planning. Yet at implementation, the rules are not respected, errors are introduced, etc...

I spend more time fixing than writing code.

Then speed... Because of the fixes and bad code quality even with frontiers model speed makes a very big difference. I (agents) spend hours daily doing reviews and fixes. 5x speed boost would make me much more productive.

And when working super fast with agents, having only one computer is limiting. Even worktrees don't solve problems because I use things like convex, chrome use, etc... and it conflicts with each others all the time.

Still many problems to solve. It's already evolved so much in the last two years.


I'll buy it from you!


This article has nothing to do with Apple.

Also, I believe that if Apple is working on blood glucose estimation, it's probably not the way described in this article.

I could be wrong that Apple will do it this way, but the current hardware supports different wavelengths PPG, (as well as the Samsung Watch Galaxy 8), which might be able to use to estimate blood glucose variations. But it's pretty complex, especially to generalize.

I wouldn't be surprised if they start like blood pressure, just estimations as to how it's going up and down.

I know that because I'm literally working on this with https://trackourhearts.com, using an AI model I created to estimate blood glucose, though I'm doing it in a personalized way so I can provide more absolute estimates but it's still incredibly hard from PPG as the wavelengths available aren't the most optimized for this.


Oh yes, I've been actually looking at integrating this and other mmwave research into my startup https://trackourhearts.com

Non-intrusive technology which can work at home to monitor people' vitals is a game changer, there are so many applications to this. Research is at the beginning.

Indeed there are privacy issues with big providers doing this, but then this really opens up so many possibilities if done well.

And if they offer you enough money to acquire the company, you'll take it, because if not you then someone else will do it. Humanity is not in fact crying out for a better panopticon.


If it's real, which we know it's not from these 'studies' being mass produced in the university citation machines for LARPing tech Simps like Hacker News users and all we have is Comcast can tell if you are perhaps in or near a room, what's the point?

You have to sit between two points to measure your heart?

My fitbit can measure my heart outside and running and in the rain and if I have an accident and also oxygen levels.

This is the most useless thing ever, for people with phobia's of wearables, so you can't get their training data anyway?

Nick Bild replicates it here https://www.youtube.com/watch?v=Cf6_PGuEiZY of course the University doesn't help at all with the replication, citation machine not a checkable (= refutable) science machine.

If I could take my watch off while I sleep and still get good heart rate / sleep tracking from devices positioned around my bed that would be great. My watch can cause skin irritation and I find it valuable but not having it on while I sleep would probably be healthier. Also as I get older if I could put a wifi device in each room that did active tracking and not have to carry a device I need to keep charged that would be great for life alert style thing, and general health monitoring.


You're making a lot of loud baseless claims really quick, aren't you?

Radar technology isn't some kind of forbidden magic. Can you do radar sensing with 2.4GHz? Yes, absolutely. Now, can you do it well, with an off-the-shelf Wi-Fi chipset, and get down to heartbeat monitoring? Only if the chipset was designed for it. Very few existing chipsets are. Still a new experimental thing.

For practical applications today, I would look instead at things like dedicated mmWave 24GHz radar chips instead - they're getting cheap now. For the future? If chip vendors that ship the usual 2.4GHz/5GHz MIMO router chipsets start putting the relevant features in, the idea would be worth visiting.


If I had the ability to track users heart rates in response to advertisements, media, political content, etc that would be quite valuable for producing content that better captured users and made them feel what I wanted them to feel. Heart rate says a lot about what we're feeling and our attention, especially if you have it all the time and can match it to what we're looking at.


Well that’s good for you but only occasionally good for the users. Often it’s the opposite, sorta gets used against them.


I mean, obviously. That's not the question though, the question is utility. There is undoubtedly utility, it's just that you are the product, not the beneficiary.


Oh okay I get your point. Yeah we’re fucked because it is pretty useful.


They are certificates of ownership.

When you own a NFT and it's in your wallet it shows that you own something. This can be used for membership for example where the owner of that NFT is automatically granted access to ... something...?

There are also smart contracts associated with NFTs... Can encode royalties and other things.

For example a creator of an NFT could encode a 5% royalty associated. This means that when that NFT is sold subsequently the original author will make 5% of the sale price.

Some people are starting to sell NFTs like a commitment to give a % of a particular revenue. It's a digital contract.

But sure. Part of owning a NFT you can often display something... Visual. Because well, we live in a visual world.. and right now it's the foundation of many NFT collections.

It's so much more than just art. The smart contract allow many more use cases in the future to prove that you own something, or are a member of something.


I think the issue is just that NFTs solve a problem that doesn't exist. Any system where an experience is gated by user attestation is necessarily self-contained (asset, payment, user account) to more effectively extract money from participants. No one is federating this, and what would they gain to do so?

There is value in perhaps validation of proof of membership in entities where they have mutual agreements to unlock extra capabilities without having to link their backends, but there are other ways to accomplish the same things... like OAuth.


I think the author is completely unaware of how things work and this piece is basically a rant on cryptos. The long version starting with saying cryptos are a scam. This sets the tone for the rest of the article.

A personal opinion vs something rooted in facts.

NFTs can be created on two primary blockchains. Ethereum and Solana. The author manifests no knowledge of those.

Solana is already proof of Stake. Ethereum is going to move to proof of Stake with Eth2.

PoS requires so much less computing power (therefore electricity) than Proof of Work. It's in fact relatively environmentally friendly.

NFTs have the potential to be a game changer. The author here sees NFTs as "Art". They're really not. Sure often NFTs are associated with Art but it's really... ownership of those pieces of Art.

But NFTs are really certificate of ownership. With smart contracts.

There is so much that can be done with NFTs. Memberships. Distributed voting. Royalties embedded in contracts so when NFTs are resold the original creator can get remunerated.


What problem do NFTs solve that regular contracts and IP law don't? As far as I'm aware, NFT sales don't usually include the rights to the IP.


Automation, efficiency and composability.

They are more easily owned by groups, transferred, packaged with others, verified with software etc.

You could think of it like the shipping container revolution but for digital assets. Sure it's possible to do these things with legacy contracts but it's far less efficient and standardized.


More easily owned by groups?! We have well established legal processes, company structure and contract law to determine who owns what, and you're to say that NFT makes this more efficient? I don't see the parallel to shipping containers at all.


Did you see that group that recently came together to buy the copy of the constitution? Took 3 days to assemble thousands of people who pooled $40M to make it happen. All their individual contributions we're accounted for and tracked.

DAOs are an order of magnitude easier to assemble and manage than traditional companies. They can buy or trade NFTs by vote done many times per day in hours. And all of the internal processes and governance can be done via software.


I don't know if NFTs solve this problem, or if there is a better solution without NFTs. But I can see a person winning buying or earning content in a game that they want to be able to authenticate. Obviously the servers of a game can authenticate that content but maybe it is possible to have content that is independently validated so that no change of ownership could prevent you from being able to claim your prize.

I don't know if that would really work and I don't know if there is a better way. But as people value digital things more and more in games I can see the idea of having a permanent version of something you achieved or bought as having an enhanced value.

I am no expert so please poke holes in this idea!


The problem of rug-pulling irl generally being illegal.


How do you enforce contracts all around the world without having to hire lawyers from all jurisdictions and hope for timely legal resolution on any jurisdictions?


If I come to your house and steal some piece of art that you hold an NFT for, the NFT isn't going to get you your art back.

If I sell it, the NFT isn't going to notice that it is on display in a museum and take appropriate action.

And so on. Smart contracts are neat, but they depend on all the same mechanisms that other contracts use.


How is a NFT enforceable in contrast? There's no way to prove who owns what address, e-contract, etc, that doesn't just fall back onto standard established contract law.


The “long version” has a very extensive explanation of why the author thinks proof of stake is useless.


actually there are studies especially from David Sinclair that shows that fasting and calorie restrictions help mice live longer and healthier.

For those interested here is a great interview with David Sinclair, Harvard Researcher on aging:

https://www.youtube.com/watch?v=8ZqAKNPxaxc


I'm very skeptical of any diet related advice based on studying mice. Mouse metabolism is very different from human metabolism.. Fasting a mouse for 24 hours will result in a fairly large loss of body mass. Fasting a person for 24 hours will result in a pound or two of weight loss.

I'm not against doing these kinds of studies on mice but the only conclusion you can really get is that we should do longer studies on animals that are closer to humans or on humans themselves.


Pound of fat, or, in SI, 453 grams of fat, is 4077 calories (9 calories per gram of fat).

Most probably, weight loss will be less than pound in water calorie restriction.

Also, there was studies on Ramadan fasting and they've found almost two fold increase of serum brain-derived neurotrophic factor at the end of fast. Level of BDNF correlates with neuroneogenesis in brain.
