You say "interesting" but as a US resident, I say "terrifying."

Biden showed a great way to subsidize industry and catalyzed the biggest expansion of building factories in generations, in forward-looking sectors that will reduce the cost of energy for all future generations in the US, providing us security and reducing the chance of another inflation spike like that caused by Russia starting wars that threaten the energy supply.

All that nascent industry is at risk of being thrown away for being too "woke" all so that we can send all the fired NCI cancer research to factories for assembling iPhones. From pipetting to tiny screws may be slightly related job skills, but it's capturing the least possible value from a generation of highly trained workers...

> why can you not wait two years before dropping out of university and start a startup afterwards?

because someone else over in the USA dropped out two years earlier than you to do this very same startup, and thus they get a head start.

Unless your novel idea is so completely novel, that nobody else but you could've done it. Most ideas are not this novel, and first mover advantage is real.

Not to mention that to make long term work out, the short term must also work out. It's a stair case - each short term period adds up and turns into long term. It is almost impossible to have a long term plan work out, if the short term is so unsuccessful that you need more funding every year.

> Regardless of the mechanism, the foundational 'conceit' of LLMs is that by dumping enough syntax (and only syntax) into a sufficiently complex system, the semantics can be induced to emerge.

Syntax has dual aspect. It is both content and behavior (code and execution, or data and rules, form and dynamics). This means syntax as behavior can process syntax as data. And this is exactly how neural net training works. Syntax as execution (the model weights and algorithm) processes syntax as data (activations and gradients). In the forward pass the model processes data, producing outputs. In the backward pass it is the weights of the model that become the data to be processed.

When such a self-generative syntactic system is in contact with an environment, in our case the training set, it can encode semantics. Inside the model data is relationally encoded in the latent space. Any new input stands in relation to all past inputs. So data creates its own semantic space with no direct access to the thing in itself. The meaning of a data point is how it stands in relation to all other data points.

Another important aspect is that this process is recursive. A recursive process can't be fully understood from outside. Godel, Turing, Chaitin prove that recursion produces blindspots, that you need to walk the recursive path to know it, you have to be it to know it. Training and inferencing models is such a process

The water carves its banks

The banks channel the water

Which is the true river?

Here, banks = model weights and water = language

I thought the whole point of serif fonts is that they are easier to read. But the author addresses your question:

> This survey focuses on serif fonts as these are the usual choice for longer documents such as articles or books (although sans-serifs have become more popular for longer text in recent years). However, in keeping with the reasoning above, I have also selected accompanying sans-serif fonts for each of the seven roman choices below (all of which have maths support of some form or another).

China's GDP (PPP) is already ~22% higher than the USA's [1]. Arguably, isn't this a better measure of value? PPP measures the real value to the citizens in a nation, and more closely measures actual economic activity.

Say a bottle of wine costs $20 in the USA, and in total one bottle is produced and sold for a total of $20 GDP. France makes 10 bottles at $2 each, for a similar GDP of $20. It's cool that the USA manages to "extract more value" from its smaller wine production, but at the end of the day, France has the stronger economy.

There's more wine to go around, more resilience to the loss of a bottle, arguably this higher production means more export capacity, more employment, more generation of wine expertise, supply chains, etc.

The nominal GDPs might be the same, but the GDP (PPP) of France in this case would be $200 to the USA's $20.

That's right. Unfortunately, the system currently forces the use of GPT-4o.

To be honest, I didn’t realize that model selection would be such an important point for users. I believed that choosing a high-quality model with strong reasoning capabilities was part of the service’s value proposition.

But lately, more users — including yourself — have been asking for support for other models like Claude Sonnet or LLaMA.

I’m now seriously considering adding an adapter feature. Thank you for your feedback — I really appreciate it.

> The positive will be that almost any service you can imagine (medical diagnosis, tax preparation, higher education) will come down to zero

Why would you want massive amounts more of those things? In fact I might even argue that medicine, taxation and education are a net negative on society already. And that to the extent that there seems to be scarcity, it's mainly a distribution problem having to do with entrenched interests and bureaucracy.

> The cost of building a new house or railway will plummet to the cost of the material and the land

That's is the actual scarcity tho.

The US has done this before, more than a few times. In fact, de-globalisation can be traced directly to the GFC, where the US did indeed print billions to bail out US banks and auto, then getting Japan and China to step up and buy UST to recapitalise the economy. PBoC in 2013 said 'no more' and launched BRI

> So it falls to the government to try and kickstart something.

why should it fall to the gov't? They're one of the worst funders of startups imho.

In these scenarios, the gov't isn't funding the business via equity, but grants - aka free money. This makes all the wrong incentives. Taxpayers don't feel the loss (not truly, like a private investor would), if the startup fails.

- They claim full open source but for several years they did not release the server.

- They claim federation is impossible… yet matrix has it.

- They claim openness but are actively hostile to linux distributions and f-droid.

- Related, getting signal from an app store is no more secure than getting any random proprietary app.

- There's a lot of allegations that they don't need VCs because they have backing from the USA army.

That bottle of wine is going to be at least 400 RMB in China, so I’m not sure how PPP can be argued here. You would need to focus on things that are less expensive in China than the UsA (services mostly, low end goods and food), but things get more expensive quickly if you go for something nice outside of a restaurant. PPP is oddly calculated given that services in china’s case are mostly what is driving its higher value, and that simply means people are paid less (and increasingly they aren’t, which means PPP will shrink closer to GDP unless their automation investments really pay off).

But if you substitute the pre-doordash system of calling up a restaurant and ordering delivery or take out, the energy savings aren't even 1%. One gallon of gas contains 34 kWh of energy, so if one delivery takes 0.5 gallons of gas, it uses enough energy to power one of your racks for an hour. How many doordash orders can be processed by one of your racks in an hour? It's got to be in the millions.

Sorry I wasn't clear, it's not a hypothesis, we have based our technology on over a decade and 50+ papers of peer-reviewed published research, and our tech is currently being used in clinical trials. We link to some of the research on our website, though there is lots more, I'll be redoing the website prior to opening pre-sales, and providing more of the research links there.

When I said "I don't have the solution yet", I meant, we are not for sale in the market yet, so I don't have anything that can help you today.

If you're suggesting "lifestyle issues" are things like, "I've got young children, and the demands of parenthood disrupt my sleep", or "I'm over 40 and my sleep quality just isn't what it used to be", then yes, this is where our capabilities shine. There is currently an issue with our capabilities in the shift-work population, but we may be able to address that prior to launch.

I like to consider these "sleep issues related to lifestyle", than "lifestyle issues".

Is that the sort of thing you were thinking of?

One of the reasons we need to speak of "restorative function" rather than "sleep quality" is that in sleep medicine they refer to sleep quality based on time metrics.

On the sleep hygiene side of things, I don't want to suggest that sleep hygiene isn't important. I used to hate it and think it was over-stated, and I think it is, when you talk about restorative function. However, if you can't get to sleep, you don't have the opportunity for restorative function. Sleep hygiene is the bus that takes you to the gym, it's not the workout.

Even if you were a local, you'd have to be "in the network" so to speak. Then you could push a meme project with some buzzwords that align with their political views and you would be allowed to dip in. Additionally, the EU is maliciously anti-wealth, even if you fund it yourself, they will actively cripple you with nonsensical regulations and taxes to make sure your company does not take off.

I'm going to go out on a limb and say because it's easiest to take whatever comes out looking interesting and sell it as a vibe ?

Like if you asked a model to help you create a coffeeshop website for a demo, it started looking more like sex shop, you just vibe with it and say that's what you wanted in the first place. I've noticed that the success rate of using AI is proportional to much you can gaslight yourself.

I’m right there with you. Modern languages have such a plethora of tooling available that DSLs and any API approaching a DSL have this massive gap unless they really embrace whatever patterns the host language’s tooling enables.

Not long ago, i had to work with a coworker’s mini language and function runner engine, which was basically a mini programming language. Except without a debugger or type checker or stack traces or any of the other million niceties we’d have had if we just used the host language to execute things ‘natively.’

That said, while the level of tooling for big languages goes up, the bar for creating yesteryear’s tooling is going down, with all the LSP tooling we have now, for example. Maybe someday we’ll get languages with tools where libraries have nice tooling without crazy dev effort, and then we’ll change our tune on DSLs.

1. There is no contradiction (I)

When you have different inputs and different outputs, that's not discrimination.

2. There is no contradiction (II)

The point I was making was about what gets published. It didn't get published.

3. There is no contradiction (III)

Please look again at the introductory sentence of the report: men and women actually appear to leave engineering at roughly the same rate and endorse the same reasons for leaving

"Roughly the same rates for the same reasons".

I repeat: "roughly the same rates for the same reasons".

That it isn't exactly the same rates and not exactly the same reasons is not a contradiction, because "exactly" wasn't claimed. It is added nuance and details that does not in any way shape or form contradict the original finding.

And it isn't "my narrative", it is what the researchers found. So it ain't a "narrative", it is the empirical data, and it isn't "mine", it is the reality as found by those researchers.

Only nonsense from a hard core fundementalist PoV really.

Any notion why you have such a PoV?

The current metric is actually quite strong -- it mirrors the real-world use case of people trying a few times and being satisfied if any of them's what they're looking for. It rewards diversity of responses.

Actually, search engines do this this too: Google something with many possible meanings -- like "egg" -- on Google, and you'll get a set of intentionally diversified results. I get Wikipedia; then a restaurant; then YouTube cooking videos; Big Green Egg's homepage; news stories about egg shortages. Each individual link is very unlike the others to maximize the chance that one of them's the one you want.

About a decade ago Google decided that all maps in Finland should have the street names in Swedish.

Which is kinda valid, in the southern and south-western parts this is done because there is a significant Swedish-speaking minority so most cities and streets have names in both languages.

But at the time I lived in central Finland, where the streets DIDN'T have official Swedish names, they just ... translated them. Which was super fun for navigating.

> force foreign manufacturers

Is it accurate to say that these companies are "forced"? Shareholders make cold, unfeeling, selfish calculations all the time. The shareholders of these companies could simply elect not to do business in China and accept the consequences of diminishing their access to the Chinese market.

Using the word "force" suggests that the largest shareholders of these corporations are victims acting under duress, which they most certainly aren't.

Did you just add Dutch as per the submitter’s request or was it part of your plan prior?

Curious because I’m trying to learn Romanian, and since it’s a less common language there are fewer resources available. So I wasn’t sure if you added Dutch with minimal amount of effort following the poster’s request.

That said, I gave your app a try with Spanish and it looks pretty good! But I didn’t see a Help page to clarify how I’m “supposed” to interact. Eg I tried saying in English “I don’t understand” (even though I know how to say that in Spanish) and it responded in Spanish which may be hard for absolute beginners. Although full immersion is much better way to learn.

I can try playing around more with it to give you some feedback.

LINQ methods build up a chain of IEnumerable/IQueryable objects, which then build up chains of IEnumerator objects each time you iterate.

These types are all .NET interfaces, which are reference types, so they're allocated on the heap. .NET's escape analysis can sometimes move reference types to the stack, but this feature is currently very limited and didn't even exist until .NET 9.

ZLinq uses generic structs to prevent these allocations at the expense of some really verbose intermediate types.

Well, the good news - and I think from the sound of your post you will take it as good news, because you care - is that you are not correct.

Some careers are vocations, and in vocations people work less for egoist reasons and more from the desire to help people. Fortunately in the UK, we still have a very strong example of a vocation - nursing. I know many nurses, none of them can be described as careerist or selfish. So to begin, we know that your statement doesn’t hold true. Nurses’ pay is appalling and career paths are limited, so I’m confident that these many datapoints generalise.

The obvious next question is why academia is not a vocation. You say it’s because it has become too like the private sector. Well, I can tell you that is also wrong, as I have spent many years in both sectors, and the private sector is much less selfish and careerist. This is surprising at first, but I think it’s about incentives.

In the private sector very few people are in direct competition with each other, and it is rarely a zero sum game. The extreme of this is startups, where founders will go to great lengths to help each other. Probably the only area their interests are not aligned is in recruitment, but it is so rare for them to be recruiting the same type of person at exactly the same time that this isn’t really an issue. There are direct competitors of course, but that situation is so exceptional as to be easily ignored.

In academia, however, the incentives encourage selfishness, competition, obstruction, and most of all vicious politics. Academics are not paid well, and mostly compete for egoist rewards such as professorships. I believe in the past this was always somewhat a problem, but it has been exacerbated by multiple factors: (a) very intelligent people mostly left, because more money could be made in finance and tech, and thus little progress can be made and there is no status resulting from genuine science, (b) governments have used research assessment exercises, nonsense bureaucracy invented by fools that encourages silly gaming of stats rather than doing real work, (c) a system of reinforcement where selfish egotists rise at the expense of real scientists, and then - consciously or not - reinforce the system they gamed, thinking it helped them up the ladder and thus must be a good system. The bad drive out the good.

Ultimately the problem is academia is now filled with politicians pretending to be scientists, and such institutional failure is I think a one way street. The only way to fix it is to create new institutions and protect them from infiltration by today’s “scientists”.

This is of course a generalisation, and there are some good eggs left, just not many. Most of them eventually realise they’re surrounded by egoist politicians and eventually leave.

> US manufacturing output is double that of China's on a per-capita basis.

If you're going around quoting those figures, you should be aware they're kinda sketchy.

Headline manufacturing output figures measure "real" output, rather than $ of output, as the latter would just be a graph of inflation and exchange rate. And when measuring "real" output, if a factory making 1TB SSDs switches to producing 2TB SSDs it has increased its output, despite the fact they're shipping the same number of boxes as they were yesterday.

Sure, the numbers say real output per worker has risen a lot since 1980. But most of the "rising efficiency" comes from the folks making 33MHz 1-core CPUs now making 5GHz 24-core CPUs. Cut out that sector and you'll discover why the US has an entire region known as the "rust belt".

For other countries USD is something they have to work for or sell something to acquire it. If they screw up they may end up in crisis being unable to obtain USD. Borrowing in their own currency will be much more limited and borrowing in USD much more costly.

USA on the other hand can just print it out of thin air and because the global USD liquidity is huge they can do it for much longer without facing the consequences of it. USA is also borrowing in currency they can just print to pay their debts. Very advantageous position for USA and they took advantage of it, imported crazy amount of products and services otherwise they wouldn't have.

This is fantastic. Looking at the absolutely massive cost differential between DIY and full-service solar installers, the DIY option looks pretty pretty tempting. My main concern was 1) actually getting through the local permitting process, and 2) what a potential purchaser would think of a DIY system when I go to sell the house.

Seeing that somebody has done it is very inspiring, and if I didn't see a high chance of moving in the next 5 years I'd be on it tomorrow.
