The other thing I would do on AIbriefs is have spacebar shift the card-list viewport right to the top and hide the top-most card.

This way reading the site entails loading the page and hitting spacebar after each card is read. This can already be done with Hackerbrain user-script while reading top-comments for any HN item - spacebar or clicking an item's green badge.

Could you make a service that converts any YT channel's feed into the more succinct version as seen with AIEtalks? Perhaps add a querystring for screenshots / timestamps / top comments inclusion?

Focus on the big channels first? Allow for an extra layer of comments that you'd host?

https://news.ycombinator.com/item?id=49423674 - YT summaries very much in demand.

The thing about Tinkering is it's a place to pickup on people's passions.

It's still important to be able to think and write. You can really put yourself on the cutting edge of things. And then you can translate that into better prompts.

The more I think about it, many of the questions people ask here on HN are very much already answered through prompting. That's sort of weird. And if you want a blog post on something, just ask an AI and they'll be pulling from blog posts anyway.

The issue is "Model Collapse" and synthetic data as outlined here: https://share.gemini.google/izx1TAOuSZc5 - my questions there were actually posed here on HN beforehand https://news.ycombinator.com/item?id=49536605 I just went and asked C3PO about it afterward. The commenter could have done the same.

In that respect, I'd be more than happy to read more direct quotes from Gemini and then read what a live hacker's take is on it. Slop provides the building blocks, and humans are the alchemists. Need both.

https://hn.algolia.com/?dateRange=pastMonth&page=0&prefix=tr... (not many returns for the last month, most are from me)

I have to say, having a background in doing detailed design work makes it much easier to write the right prompt. Also, having the ability to deliver a theme-switcher like this is very handy. There is a tradeoff. Adding this switching took about 1hr 10mins. Last 10% of the result always the most time-consuming.

Dark/light switching is also important.

If I had built this from the ground up manually, I could implement my own design and fiddle with things on a minute level but this type of granularity gets lost when building at speed.

Regarding robotaxis:

"The side of the vehicle features a rugged touch screen. You receive a 4-digit PIN via text or app notification, walk up to the vehicle, and type that code into the car's screen to open the specific compartment holding your order."

https://share.gemini.google/wzuailgn9yih

You could roll up with your "unpowered keypad" to the taxi and key in a PIN via that. Saves the car from installing one, and there'd be an extra layer of security whereby your card could be coupled with the drop-off. It makes sense when you don't have or want a smartphone. (see below)

"External touchscreens mounted on autonomous delivery vehicles face several severe real-world challenges, making them one of the highest-maintenance hardware components on the vehicle... By shifting authentication back to the customer's phone, operators eliminate the weatherproofing and vandalism headaches of external screens while speeding up the drop-off process."

The card can work with Lay-buy/lay-by:

_____

You go into a store, pick something out. Get a crypto address for it and the amount required with your special card. They set the thing aside. You leave and return to the store when the transaction has gone through and get your stuff.

You don't pay immediately because you don't want to be walking around with a crypto wallet or a crypto debit card. The merchant doesn't want to pay fees either when dealing with an intermediary. There's no fiat conversion either, at least not as a given.

_____

Gemini says this:

"If you want to do this today, ask the merchant to print or email you a dynamic checkout invoice/QR code so you can complete the transfer on your own device later."

But how widespread is that?

"It is virtually non-existent at retail scale. While the underlying technology exists, you will practically never encounter this specific workflow in the wild."

https://share.gemini.google/ZBHVZo47ZSn1

The "special card" is an evolution of that use-case and organizes it better. You can leave home without thinking about dollars, ready to pay with crypto and not worry about being robbed. No worrying about stockpiling a bunch of receipts either. It's just a 2-step buying process, that's the downside. The shop also has to hope you end up paying once they set it aside. Maybe they'll need a deposit. They can offer deliveries?

Another idea is to pay online and collect it later. Use the card to authenticate yourself when you collect. That would need some decent tech backing it. Make it non-committal where if you don't collect within a certain time frame, you get your money back but lose a penalty chunk.

Isn't this what smart contracts are designed for - crypto transactions tied to real world events? The "special card" provides those events.

[ conversation continued via link above ]

Another interesting use case would be using the card as part of a crypto escrow.

The problems being solved here are:

- walking around with a device that can access a large wallet that could be accessed under duress or coercion

- Key Pairs are hard to remember and type

___

- pre-pay an escrow online with $100

- have a payment card in your pocket

- meet person with another card

- set a payment amount

- touch cards

- escrow unlocks the amount as soon as either card pushes the update online - which if online could be immediately

- card confirms the transaction??

- can also delay the transaction, and if both cards are lost in the meantime, the transaction doesn't go through

- can also specify the payment amount as "set later"

- receiver can also request an amount

- escrow can be funded after the meeting

- good for 1:many payments too, eg splitting a bill

____

cards could also be Key Pair generators, for transferring public keys to other cards, with the exchange recorded for later use. No escrow required. A lot of benefits over handing out printed QR codes of addresses.

I wonder if it can be applied to robo-couriers and drone drop-offs. One of those comes to your door, you get your stuff, and you pass something that is powered-up over its sensor and it drives off. It's the equivalent of signing-off on a delivery. The sensor obtains and stores information about you as well.

Maybe I've got it wrong and the recipient needs the sensor and the driver has the powered device that only switches on when it is ready to do the drop off.

With this card, what are the information transfer and storage scenarios? Would be great to see a table. Can the two parties both exchange and store information with minimal power? A card with a little battery and power-on button? Card can have some type of port? Can it be be used as a crypto wallet with a kill switch in the event of a robbery or home invasion?

I think this is important in Hub-and-Spoke communities (previous comment) where population densities decrease but there'll still have to be a lot of exchange going on. Offline-based interactions are a good idea too - keep the airwaves clean.

That could also become a robotic service too.

But to really zoom out, as someone else pointed out:

"What would homesteading independence look like in the 21st century in terms of sustainability and so forth?"

I am thinking here about more than just infinite intelligence, but infinite power. Science fact presenting itself as science fiction. And for that you'd need locked-up and hidden technology. Also ways to deal with all the waste and by-products of human evolution. Well said. Supporting the environment that supports us.

So Hub-and-Spoke layouts over Megacities. Providing breathing space for land and people. As much DIY as possible using scalable best-practices with commodity items. Censorship-resistant. Free-flowing funds, energy and information. Protected whistleblowers using a local-first Fediverse that can toggle anonymity on/off. Harnessing waste streams and up-cycling them, and doing the full "Earth shift" while still reaching for the stars!

Every time you make a cc purchase online, the seller, if they get your details directly can then go out and use your details to make purchases of their own from your card. That's insane, let alone having your name and address details. No wonder cc companies get fraud.

If I am going to use a credit card, let me hand over the number, and then send me an email to confirm the purchase. Not sure what the flow of that would be and if/how to use confirmation codes. Also, the last thing I'd want is another "app". Maybe optional 2FA.

Thanks.

Crypto debit cards are on the rise anyway.

Another idea would be to have a once-only disposable CC number generator. New purchase, get new number. Also, when new numbers are generated, the bank can record the who/when/where of the request and it can be matched with the when/where/how it is used later, and how many times to get a clue if an account is compromised as a fallback protection.

Imagine if those numbers went on a blockchain for merchants to use. They could see if/when a number was already used, but not necessarily need to use/integrate with it - but the bank would. Crypto address generators are commonplace now but addresses are very hard to key-in. So the blockchain would be a security layer on top of the conventional transaction, which could work without it if need be.

Increasingly, I'm seeing crypto as the best thing long-term. No one's going to deny me service based on who I am and where I live (or could be living,) let alone giving that info over to third parties unnecessarily. No false positives leading to rejection either based on that information which shouldn't even be asked for. Identity should be a choice, not a requirement or a coercion. Like this, even bitcoin enables a high degree of anonymity.

What's with this whole "Billing Address" bull^^^^? No one needs to know that when I buy something with cash at a supermarket or use a credit card at a gas station.

If someone wants to know exactly who I am and where I am (or could be) then there should be a card for that which will co-exist with the crypto. Does PayPal provide names of buyers to sellers? Also, a buyer's protection thing could exist as some type of adjunct escrow service for sellers to use.

"He warned investors never to share their 24-word recovery phrase and said large holders should avoid keeping direct access to their full holdings at home."

That's the last thing that should be solved. Remove the temptation for crime.

I've been talking to the chatbot on ChatGPT... very valuable tool... but I have to remind it to do really trivial and assumed things like "apply changes over the last set" "should I reupload the file" "the file is actually named ...." "Are you sure about that?" these type of things. It's holding my hand, I'm holding its hand. It's like an absent-minded professor or C3PO. Gemini has had serious issues too. Look out for misinformation, imprecision, ensh$%^&fication and favoritism.

At least it can say "you're right!"

Also, Claude (clause?) just wrote:

Has anyone else seen that? That was the first prompt I ever saw, pre-filled.

Imagine a big truck blowing its front tyre at 60mph in the middle of nowhere. Now think of your business. Or one day your extended family decides to hold you hostage at gunpoint and holds a ransom on you. Or Order 66 in Revenge of the Sith. Just be alert, not alarmed. AI insurance is where it's at. If it makes you dependent then there are clear risks.

McCauley (played by Robert De Niro [Heat / 1995] ):

I'll say.

Imported about 750 feeds. Still buggy.

A lot of fiddling. Have to run PHP, PHP-FHM, install CURL, and messed around with configuration files.

Also needs a PHP proxy script to run alongside the HTML and ensure URI encoding.

Not easy done but can now disable CORS Unblock in the browser. Yet now these extra things have to run as services all the time.

Sidepage doesn't seem quite right for me at this stage but thanks for the ideas. It looks like it could do the same job, though. As long as an AI can provide detailed instructions and troubleshooting, it'll lower the barriers-to-entry.

I think the future may well be a modified browser with CORS Unblocking built-in (or some type of proxy alternative.) Have it offer 1000s of free "page-apps" from the get-go. Easy development and ubiquitous platform is the key. Offline button clearly marked and traffic/bandwidth data collection and window.

P2P and micropayments stuff could be interesting.

Overall, the downfall of feeds has either pulled people into the walled gardens or pushed them offline completely. Look at the new Commodore minimalist phone.

Yet having 1GB+ databases possible in browsers by default is something that could pave the way for some cool stuff. https://rxdb.info/articles/indexeddb-max-storage-limit.html

The unique thing about HTML apps is that there could be a "directory download" of say the best 1000 apps every month for people to run locally with imports also downloaded and security audited beforehand. That would be ideal.

GreasyFork checks for security problems and best practices in their scripts with community moderation a large component. https://share.gemini.google/VwomSQkChNWS

How I see it, there could be a code freeze period (quarantine) and if no issues arise, the HTML is bundled into the 1000 monthly thing.

Yes. Ideally that box would be in a sidebar. On that note: Gemini Chat Sidebar, Sidebar with Gemini and the official Gemini in Chrome all come to mind, for example.

Also, have you seen these: https://greasyfork.org/en/scripts/by-site/youtube.com?site=y...

Seems like a crowded space, that could be a good thing if you differentiate well.
