Is self-evaluation the blind spot of AI? Or can we trust LLMs to judge themselves?
I benchmarked evaluation models/methods like LLM-as-a-judge, HHEM, Prometheus, Lynx, TLM across 6 RAG applications.

Evaluation models work surprisingly well in practice.

I hope continued research into reference-free evaluations helps users gain more confidence in their AI-generated outputs.
I live in Switzerland - TWINT has other differences as well. To start, its settlement is not immediate as Pix's. As you point out, it is also not standardised.
That doesn't really solve any of those problems.

What you actually need is mass production, and a regulatory environment that facilitates the same, e.g. by putting most of the certification in the design phase and then making production certification limited to the matter of whether what was built follows the certified spec.

The ideal would be to limit the on-site construction to common fungible commodities like pouring concrete and have any reactor-specific components mass produced in a factory. Then the same factory can be producing components for reactors whether they're going up in New York or Seattle or London and you get your economies of scale.
Of course there is still the downside that it doesn't work very well.
Not touching D3.js since Observable.
Not presently. We'll do an enterprise push at a later date.
I use search engines every day (primarily kagi). But I will use a fast llm with a search tool for some things, like providing context about a news story etc, (primarily gemini 2.0 flash with "grounding" on).
If I attach a pgp signature in an email, it’s trivial for a MITM attack to replace my signature with their own. Without any way to verify who owns the key that was used to sign your message, what good is it? I suppose I could publish my key on my website too, but that’s a usability nightmare for everyone involved. A mitm attack could also just strip off the signature and alter the message I would be none the wiser.

Signal uses a much more complex key ratcheting system. It’s TOFU, but the key rotates with each message I send. The first message is vulnerable to a MITM attack, but because of the way signal works, if I can ever send a single message to you which isn’t MITM-ed, every message sent thereafter will be secure. The earlier keys are also published to make messages deniable. (Aka OTR).

Even then, if you want to verify who you’re talking to, you can click on someone’s name in signal and click “View safety number” and verify the code through a separate channel. Like, in person or over a text message or something.

Because your code is different for every conversation, it protects against correlation attacks. That is to say, a 3rd party watching the traffic can’t tell that all of the messages you send to different recipients came from the same person. Email+PGP doesn’t encrypt the most important information - which is the identity of the sender and receiver.

Signal is way better than pgp-over-email in every regard. The UI is better. There’s no encouragement to publish your keys or your social network. And the security ratchet is better than the static key that pgp uses. I’d pick it every time.
chatgpt search has completely taken over my search, it's just better. Great that you then get to have follow up questions to narrow in or ask more. So common thing, looking for a product, it will find it, you can ask for other options, or ask it about the reviews for a specific product (it will give a summary and links, and may even embed a youtbue review), best pricing, nearest retailer, .... oh, none in your area, best place to order it from.... etc etc. I just have zero need for the classic search engine any more.
I wonder how the tariffs will play into this.
> Because the US has emphasized college as the only respectable education path, as well as the only path to well paid jobs.

There's this idea that the shift to college and white collar jobs was some artificial push, but it seems more like an incredibly natural and obvious move to me. A lot of blue collar work is just not super great from a working conditions and pay perspective and while not every white collar job is awesome, the pay and conditions are generally better and at their best can be incredibly intellectually stimulating. My Dad started out working in an industrial plant but pretty quickly ended up going to college to get a computer science degree because that job sounded way better than what he was doing...and that was way back when those kind of factory jobs were still a reasonable way to make a living.

I can somewhat agree with the Dirty Jobs philosophy that non-college careers can be valuable and the right choice for some people, and the world after all still needs crab fishermen. But it's really easy to slip into overly romanticizing those careers even to the point of suggesting they're better than getting a degree.
Really? What stock service would have a selection of squirrels in a high school setting doing various math or other subject related things?

To think any/all combined stock services would be the end all is just unrealistic. Sure, someone one might have settled on something just because they got tired of scrolling (much like streaming video services), that does not mean they are happy with their selection. Just happy to be done.

Now, with generativeAI, they can have squirrels doing anything in any setting they can describe. If they don't like it, they can just tweak the description until they are happy. It's an obvious plus for them.

I never drank the kool-aid to be all gung-ho on this boom/fad, but I'm not going to be so obstinate that I refuse to accept some people find it quite useful. May someone make all the squirrel attending highschool generative art they want, but you can't tell me some stock place is good 'nuff for everything.

We don't need to build literally everything ourselves, that's a reductionist argument, we just need to become a lot more productive than we are now.
An MP represents everyone in his constituency regardless of whether they all voted for him. That is his job. He represents the constituency. It is quite false to say that someone lacks representation in Parliament because his preferred candidate was unsuccessful. Everyone's preferred candidates obviously can't all be successful! That wouldn't be democracy.

>let alone government

The idea that everyone is entitled to have his preferred local candidate become a minister of the Crown is truly absurd.

>artificial consensus ... Managed democracy ... arbitrary

I don't know what this means.

Have you ever not hated LLMs?
Everyone still uses search for news, fact checking and as a nat language dns (eg: website for golang) The two worlds are en route for a merger and Google will most likely come out ahead.

That’s if they can swing the immense ads machine (and by that I mean the ads organisation not the tech) and point it at a new world and a different GTM strategy.

They still haven’t figured out how to properly incentivise content producers. A lazy way would be to display ads that the source websites would display alongside the summary or llm generated response and pass on any CPM to the source.
>My plan is to be acquired by a news company.

I feel like this is going about it the wrong way. This puzzle game licensed by The Atlantic for example, was made because they wanted to provide a fun game experience for their patrons.

With games, the best games come from an organic experience. Its almost worse to have a preset plan.

Not to mention, making a game is work - you have to have approachability, rules think through alot of scenarios even for "simple" games to make sure things make sense etc - and if you haven't even done it before I highly suggest you actually try and make a game first
It's a shame - and I'm not sure why they did it other than to use D3.js' popularity promote Observable.

Yes, I have. If I want something to read the page for me, then that's where LLMs come in.

But what I'm talking about is when I want to read the page for myself. Waste of time to have to wait for an LLM to chew on it.
It's time to bind "Please be concise in your answer and only mention important details. Use a single paragraph and avoid lists. Keep me in the discussion, I'll ask for details later." to F1.

This seems about as obvious as it gets.

Wise's unsupported business list is two pages long https://wise.com/us/acceptable-use-policy

and the transaction size limits is also too low, for me (I think you can send multiple in quick succession though)

to avoid random fintech platform and bank scrutiny for normal transactions and the higher scrutiny given to international transfers, I've used crypto for over a decade. For investment, to pay or be paid by vendors in other countries. Places where paypal/wise/revolute/n26 will flag, hold, or western union was the only option. This hasn't changed in that decade, only more onramps and offramps for crypto has changed for more proliferation.

once our crypto is within our respective domestic jurisdictions, cashing out typically has an extremely fast, non-scrutinized option, similar in speed to Pix

another comment mentioned that the Bank of International Settlements is working on instant cross border transactions, I suspect the scrutiny and transaction size limits will remain inferior to the unlimited size that crypto provides, and lack of scrutiny that a transaction converted to a domestic transaction will provide.

Been using stablecoins for a decade and the transaction costs have dropped as blockspace has become more abundant, and the stablecoin issuers create and redeem for free.

there is also the benefit of not needing the domestic currency or banking rails, since the crypto ecosystem has many investment options for different risk profiles, and many vendors to pay for goods and services.

It is very common that people do not find this competitive because they aren't aware they have a problem, or don't have a problem. But many people do encounter a friction once they branch out into another industry to try to change their circumstances, or earn larger amounts. That attracts enough people to crypto.

It absolutely has been for me. It'll be a cold day in Hell before I pay money for something that's ad-supported.

It's still not clear how this is supposed to work for heating load.

For years I was screaming at Google because I just wanted answers rather than endless blue links for me to research my answer. LLMs were such an amazing innovation in that it provides answers instead but now I'm finding my way back to keyword search. I think I'm still searching about 15% of the time.
I'm not disagreeing with you. CBDCs are dumb from a financial standpoint.

Yep. Pretty much.

Because if X country is doing it, Y country should do it as well, and then export the associated infra to a less developed country. By the 2020s, it became a completion between Chinese vs Indian consultancies (ay least in Africa)

You have to remember the Cryptocurrency bubble was going strong until 2023 when the FTX scandal happened.

Hiring a team of 20-30 engineers isn't that expensive for a moonshot that makes it easier to negotiate if that moonshot somehow actually has an impact on global finance.

Of course, most moonshots fail, but it still doesn't hurt to have something back of pocket or build some infra if needed.
I loved hearing then in Hampstead Woods in North London, and also the trees along the New River (artificial canal intended to bring fresh water into the city, built in Tudor times) - but it was quite difficult to see the little buggers. I did have a spotted one come to our bird table in Lincoln UK a some years ago, and my little brother who lives near Grantham quite often sees them.

Lovely birds.
Studio Ghibli might not have been affected yet, but only because the technology is not there yet. What's going to happen when someone can make a competing movie in their style with just a prompt? Should we all just be okay with it because it's been decided that Studio Ghibli has made enough money?

If the effort required to create that can just be ingested by a machine and replicated without consequence, how would it be viable for someone to justify that kind of investment? Where would the next evolution of the art form come from? Even if some company put in the time to create something amazing using AI that does require an investment, the precedent is that it can just be ingested and copied without consequence.

I think aside from what is legal, we need to think about what kind of world we want to live in. We can already plainly see what social media has done to the world. What do you honestly think the world will look like once this plays out?
> I keep seeing people advocating that the idea that we should build everything, and every piece or everything, here is a good one.

“Everything” may be a bit extreme, but seriously, have you already forgotten the lessons learned during the Covid supply shocks? It’s important to be at least somewhat self-reliant as a nation, especially when the country we are VERY reliant on is not a friendly one.

It seems to be a pretty high cost, at more than $6 per assertion. Wikidata - the closest thing we have to a "backbone for the Semantic Web" right now - contains around 1.6G bare assertions describing 115M real-world entities, and that's a purely volunteer project.

I used GPT-4o for some image editing (adding or removing things) to an image of a person and they distort the look of the people after each edit but (Gemini Flash + image out) did much better.

The main problem is there is little control. For example I asked to add a helicopter to an image in a ski resort but then it seems cumbersome for me to have to write a full paragraph to describe where exactly I want this helicopter to be rather than if I could just do it by dragging things with a mouse.
Can we just agree that a system where every user/member needs to keep a large if not the entirety of the history of transactions is never going to work well?

Fine keep using crypto as a store of “value” but as a way to handle day to day transactions it has failed.
My town used to host the company that made the "Bridgeport machine"(the name of the town itself) and the Singer company. When both left, it relied on banking to pick up the slack, but now that seems to be falling apart as well with the skyline mostly empty after the banks left post-pandemic. Whenever I machine something on a Bridgeport I think about it.

Well they are better in the sense that you can’t really outsource HVAC or plumbing work to India. The downside of course, and the reason that so many Americans fell out of love with the trades, is that we’re extremely eager to import foreign labor, legally or otherwise, to suppress wages.

Novelty isn't inherently good. The word "modern" is the most overused word in the English language on this forum. Every new Javascript framework is "modern" and by implication good.

There is nothing non-representative about FPP. It has nothing to do with parties. It is a non-party-based system. There is no a priori reason why it is "more democratic" for the proportions of seats in Parliament when split by parti to correspond to the proportions of votes for candidates from those parties. You can declare that you define "democraticness" to be a measure of the extent to which that is true, but there is no logical reason for them to correspond and no good argument that they should.

It is assumed as axiomatically good and you work backwards from there. Party-proportionality is democracy, therefore list-based proportional representation is more democratic. Well only if you redefine "democratic" first to mean "proportional", which isn't what anyone understood it to mean in the past and isn't the way the term is commonly used in any other context.
> Given the fact that the central government uses taxes to fund the creation and managements of a countries currency

That's not a fact, in fact it's typically the other way round, issuing a currency is generally profitable and the profits typically flow into the general government budget: https://en.wikipedia.org/wiki/Seigniorage It's managed by the central bank, though, btw, which is considered separate from the government for governance reasons.

Of course, none of that stands in the way of creating public payments infrastructure.
Badly managed companies often hire some very good talent which can allow them to sometimes do very impressive things in spite of themselves.

On top of that, the BIS isnt even needed for global real time payments. A company like Wise (formerly transferwise) or any similar entity can just hold accounts in each country and if the local settlement is real time they can also do real time global settlement by just updating their db and sending the money real time in the receiving location.
Can you comment a bit on what you liked about them, especially compared to Tailscale?
