I tried Lithium Orotate at the typical supplement dose. After the first week it left me feeling rather blah. Discontinuing it reversed the feeling after a few days.

I repeated this a couple more times with a repeatable outcome.

It’s very hyped in supplement communities with claims that it’s perfectly safe and side effect free. I didn’t get any kidney damage or anything, but I also didn’t get a positive benefit from it. Only subtle negatives that built up over a week.

Yeah me too, so it's found in many authoritative places.

And I might be wrong but my understanding is that it's not wrong per-se, it's just wildly incomplete. Which, is kind of like the same as wrong. But I believe the airfoil design does indeed have the effect described which does contribute to lift somewhat right? Or am I just a victim of the misconception.

I suspect this is the case, much like with Apple Intelligence as well. Case in point, see the early Apple notification summaries of text messages. "Mom: That hike killed me!" AI Summary: "Mom died on hike."

All it needs though is a sandbox to execute the action in, and an approval flow for the user to review the changes the agent wants to make, or make revisions. Why does it have to be all or nothing? "Hey Google, schedule a meeting with x for next week when we are both available" "Google: OK, here's a preview of the calendar invite - do you want me to send it, or make changes, or cancel?"

What happened to those two distinct questions? What point were you trying to make in your previous comment? I specifically asked for clarification on your comment and instead of answering that direct question, you went right back to debating the original issue, even merging the two questions in the exact way that you complained about me doing it.

It is also bizarre how much of this discussion is had purely from a US-Japanese perspective as if the Soviet Union declaring war on Japan wasn't even worthy of a footnote.

Yeah, but I disagree with you a bit. If it were less heavily scripted, it may or may not be going well, but it would feel very different from this and would not be copping the same criticisms. Or if they unashamedly leant into the scriptedness and didn't try to simulate normal human interaction, they would be criticised for being "wooden" or whatever, but it wouldn't have this slightly creepy vibe.

Your link literally says pressure differential is the reason, and that curvature matters:

> “What actually causes lift is introducing a shape into the airflow, which curves the streamlines and introduces pressure changes – lower pressure on the upper surface and higher pressure on the lower surface,” clarified Babinsky, from the Department of Engineering. “This is why a flat surface like a sail is able to cause lift – here the distance on each side is the same but it is slightly curved when it is rigged and so it acts as an aerofoil. In other words, it’s the curvature that creates lift, not the distance.”

So I'd characterize this answer as "correct, but incomplete" or "correct, but simplified". It's a case where a PhD in fluid dynamics might state the explanation one way to an expert audience, but another way to a room full of children.

> Am I missing something?

Go grab a thin colored sheet of plastic (or anything transparent will do). Hold it up to the sky and look through it. What color is the sky?

Now yes, the sky will be yellow or whatever color the plastic is but if you go around and start telling everyone that they'll call you crazy.

If you really want to get into it, colors are also determined by what everyone else sees. You could be colorblind and what color something is to you is not what color that thing is to everybody else. Or you could take the sun itself, which everyone agrees is yellow except some armchair expert redditor who once heard in science class that "the sun is green" and is willing to discount his eyes rather than hear the rest of the discussion where it is white because it emits in a broad spectrum and appears yellow on Earth because the blue sky removes some colors before we can see it. So you can imagine a future civilization where most people don't live on Earth might call the sun "white" but for now everyone will call it that because it is yellow. This is a bit in your favor but you might notice the main point of my previous comment isn't about blood looking blue so much as the pigs being fucking neon blue and that blue looks nothing like blood and could not be mistaken for the same thing. Look at the pictures.

over the last week or so I have put probably close to 70 hours into playing around with cursor and claude code and a few other tools (its become my new obsession). I've been blown away by how good and reliable it is now. That said the reality is in my experience the only models that actually work in any sort of reliable way are claude models. I dont care what any benchmark says because the only thing that actually matters is actual use. I'm really hoping that this new gpt model actually works for this usecase because competition is great and the price is also great.

I'm not so sure about that, at least not for all of them. Same with cryptocurrencies: there seem to be plenty of folks who really seem to believe all the nonsense. I'm not entirely sure what's worse: the true believers who think they're on a mission from God, or the cynical nihilists who view the world as their person wankdoll to use and abuse.

Of course, with the promise of "we're going to improve the world, and oh yeah, you're going to be rich while improving the world" there's a huge amount of incentive to rationalise anything. Mix with plenty of FOMO and you've got a recipe for some pretty crazy stuff.

Who is this "everyone"? Just because RISCV ISA is open doesn't mean the ecosystem will be too. Because wile the ARM ISA is licensable by everyone so in theory everyone can be making X86 PCs, the current PC ARM ecosystem is way worse and way more locked down than X86.

Reminds me when people wanted Intel to die and then they realized AMD started raising their prices with no competition and they tough that maybe AMD isn't their friend and is like any other for profit corporation.

So I have no idea why people want to see the most open PC ecosystem die. What kind of short sighted masochism is this?

> the value of the land is determined by "best and highest use"

Absolutely valid to say that "best and highest use" is vague and untrustworthy at best, but it's said this way to avoid getting trapped in the weeds of what exactly it means. Broadly speaking, "best and highest use" is entirely contextual to the land in question. The "best" use for 40 acres of nutrient-rich soil an hour away from the nearest city is going to be agriculture. While a plot of land smack dab in the middle of mainstreet in a rural town would probably be a commercial building or a mixed use building offering an apartment(s) above a shop or restaurant of some kind. Downtown in a metropolis would be some multi-storied residential or business/commercial building, while the middle of nowhere filled with trees is forestry and maybe mining. Everything is contextual.

Who determines the "best" use case is usually delegated to a free market of land value appraisers. It seems counter-intuitive to leave so much leeway at this part, but consider that land value taxation is attempting to best capture the true value of the land. Meaning that land owners want the lowest possible valuation of their land to pay less taxes, but since land can't be hidden, it's (in theory) hard to fake the value of your land. I can't argue my house in an urban community is relatively worthless when A) every neighboring piece of land will have more or less the same value, and B) everyone can see where the land my house is located and what's around it.

This plays into your first comment, if your neighbor adds a bunch of improvements to his land, if you and your other neighbors gain benefit from those improvements (they opened a store, or a school, or installed a modern sewer system or clean drinking water system, or created a private land reserve, and you and your property have access to these), then yes your land would see an increase in value as a result. However, these types of improvements are rarely the case, and are mostly handled by some form of government. The same with a neighbor "overpaying", since in theory they wouldn't "overpay", they'd just be paying the value that the land is assessed at.

Alternatively, if your neighborhood is run down compared to something brand new and shiny, and all of your neighbors decide to clean things up and do renovations and increase the overall perceived value of the neighborhood, then yes you'd see your property value increase as a result of others actions. But this is no different than when communities go through "urban renewal" and other programs that artificially increase the communities' value as a result of private and public funding.

I'm not sure how to describe my political inclinations. I've voted libertarian in multiple elections at multiple levels but don't usually vote that way and am not sure I'd use that label.

I have mixed feelings too. I donate to public media and use it regularly, but am empathetic to arguments against the government funding it. At the same time something about it makes me uneasy.

Some of it is I just think public media is a good return on investment, even if it's not ethically compelled. However, if I'm honest, I think my real concern is that I don't believe this was done in good faith, and believe it reflects an implicit but real impingement on freedom of speech. I do think sometimes context matters, in terms of understanding a broader pattern, and in this case that pattern points to restrictions on speech. The impartiality rationale for the decision is undermined, for example, when you have the press pool being chosen by the administration (rather than journalists; https://www.pbs.org/newshour/show/white-house-says-it-will-d...) and composed of ultra right wing organizations the way it is. It points to a lack of impartiality on the part of the government, and therefore, an imposition on free speech rights. It's hypocritical to complain about NPR being biased, even while you decide who will cover you.

I don't think it's possible to have completely neutral or impartial news coverage, and I think that reality was abused in the discussions about why to eliminate funding. Maybe the law was set up to fail in that regard — I think that's a fair argument — but regardless this, like a lot of other decisions, seems like the wrong one to me by virtue of a much larger string of decisions.

There are many, many K.I.S.S. cars out there. They are used, old, cheap and can still run great. Personally, I really do not want to have a car with any kind of computerization (other than a basic ECU) and more complexity and weight than it absolutely needs to have. Fortunately, I'll be fine - I doubt the supply of old cars runs out before I shuffle off this mortal coil.

I knew at one point some engineers who added RFC2549 to see if the salespeople were just being yesmen. A few years later I had similar problems with HSM salesman lying about Java support in their products so I can sympathize. Buying a product you cannot use without extreme effort is the pits.

One of them put in a bid to Cisco and got a reply back saying something like they were working on it but having some issues with the birds.

I chose a single site-wide /.well-known/aura.json manifest primarily for agent efficiency. The goal is for an agent to understand the website s entire capability map with a single, predictable request, rather than having to crawl and parse individual pages to piece that map together. Aura is conceptually similar to robots.txt one file that defines the rules and possibilities for the whole site.

However you are right that context is critical for individual URLs. I handle that with the dynamic aura-state http header. While the manifest is the static map of everything possible, the aura-state header in each response tells the agent what's available right now for that specific page or state. (e.g "you are logged in so create_post is now available").

So i get the best of both worlds efficient site-wide discovery dynamic *state-aware execution

I have a suspicion that while the major AI companies have been pretty samey and competing in the same space for a while now, the market is going to force them to differentiate a bit, and we're going to see OpenAI begin to lose the race toward extremely high levels of intelligence instead choosing to focus on justifying their valuations by optimizing cost and for conversational/normal intelligence/personal assistant use-cases. After all, most of their users just want to use it to cheat at school, get relationship advice, and write business emails. They also have Ive's company to continue investing in.

Meanwhile, Anthropic & Google have more room in their P/S ratios to continue to spend effort on logarithmic intelligence gains.

Doesn't mean we won't see more and more intelligent models out of OpenAI, especially in the o-series, but at some point you have to make payroll and reality hits.

> The only drawback

You also spend a lot more time on communication. If you have one person who is the resource for X, they can spend their time doing X and don't have to spend time on coordination. When the procedures for doing X change, only one person needs to figure it out, etc.

That doesn't mean having a single person is the right decision, the benefits of having multiple people are important; just want to be clear about the drawbacks of multiple people doing the work.

"Short time"? Look, I appreciate that you mean the development time for the feature to be added, but S0+network was introduced over a decade ago. Early versions were in Windows 8. It shipped in Windows 8.1 in 2013. Your link is from 2025 where they're talking about S3 support no longer existing at the hardware level.

I'm really happy BSD is getting support, but they literally waited until hardware for the deprecated standard to cease to exist before implementing the new support.

That's not a short amount of time.

Better if you see it for yourself. Setup GitHub MCP and enable all tools. It will start using wrong tools at wrong time, overuse it. Add languageserver-mcp, and it suddenly will start trying to use it for file edits and create a huge mess in files.

I have nixos mcp server available to search documentation and packages, but it often starts using it for entirely different things.

It's almost like when you tell someone not to think about an elephant, and they can't stop thinking - if you provide it with a tool, it will try to use it. That's why sub-agents are better because you can limit tool availability.

I use tidewave mcp and as soon as it uses a single tool from it, claude becomes obsessed with it, I saw it waste entire context running evals there without doing any file edits.

This reaction didn't emerge in a vacuum, and also, toxicity flows both ways. In the tech field we've been continually bombarded for 2+ years about how this tech is going to change the world and how it is going to replace us, and with such a level of drama that becoming a cynic appears to be the only thing you can do to stay sane.

So, if sama says this is going to be totally revolutionary for months, then uploads a Death Star reference the night before and then when they show it off the tech is not as good as proposed, laughter is the only logical conclusion.

Pressure differential is absolutely one of the main components of lift (although I believe conservation of momentum is another - the coanda effect changes the direction of the airflows and there's 2nd law stuff happening on the bottom edge too), but the idea that the pressure differential is caused by the fact that "air over the top has to travel farther in the same amount of time" because the airfoil is curved is completely incorrect, as the video in my link shows.

Sorry, I know nothing about this topic, but this is how it was explained to me every time it's come up throughout my life. Could you explain a bit more?

I've always been under the impression that flat-plate airfoils can't generate lift without a positive angle-of-attack - where lift is generated through the separate mechanism of the air pushing against an angled plane? But a modern airfoil can, because of this effect.

And that if you flip them upside down, a flat plate is more efficient and requires less angle-of-attack than the standard airfoil shape because now the lift advantage is working to generate a downforce.

I just tried to search Google, but I'm finding all sorts of conflicting answers, with only a vague consensus that the AI-provided answer above is, in fact, correct. The shape of the wing causes pressure differences that generate lift in conjunction with multiple other effects that also generate lift by pushing or redirecting air downward.

Sure.

I have tried Bash namerefs. I found them to be kinda awkward, since you need to name them uniquely. So, you have to pretend that they are global variables, even though they are declared inside a function, which makes their usage verbose.

Here, this could look like:

split_by_double_dash() { declare -n split_by_double_dash_before=$1 declare -n split_by_double_dash_after=$2 split_by_double_dash_before=() split_by_double_dash_after=() ... }

How are they mindblowing? This was all possible on Claude 6 months ago.

> Major progress on multiple fronts

You mean marginal, tiny fraction of % progress on a couple of fronts? Cause it sounds like we are not seeing the same presentation.

> Yet, I like what I'm seeing.

Most of us don't

> So -- they did not invent AGI yet.

I am all for constant improvements and iterations over time, but with this pace of marginal tweak-like changes, they are gonna reach AGI never. And yes, we are laughing because sama has been talking big on agi for so long, and even with all the money and attention he can't be able to be even remotely close to it. Same for Zuck's comment on superintelligence. These are just salesmen, and we are laughing at them when their big words don't match their tiny results. What's wrong with that?
by amilios | 2025-08-07 18:00:53+00:00
I believe the deflection is the high-level explanation. Things like the Bernoulli effect and the air on the top of the airfoil travelling faster (it does -- far faster than the equal transit time theory implies actually), are the "instantiation" or outcomes of the air deflection. This is my understanding. Hence airplanes can fly upside down because even if the airfoil is upside down, it's still deflecting the air, just perhaps less efficiently (I think it's true that planes flying upside down need a more extreme angle of attack to maintain lift, so this makes sense)

I get you.

I think for me, just knowing what is probably on the teleprompter, and what is not, I am willing to bet a lot of the "wooden" vibe you are getting is actually NOT scripted.

There is no way for people to remember that 20 minutes of dialog, so when they are not looking at the camera, that is unscripted, and viceversa.

One weird question is why is it that they can win the math Olympiad but can’t count the r’s in strawberry. I mean I know they fixed the r’s problem, but it seems like they’re really focused much more on raising the ceiling than the floor. In many ways, counting r’s in strawberry and the like are the _more_ interesting problem, and yet that’s not a substantial part of the sales pitch.

Employees, by and large, all share three common desires:

* How do I get promoted?

* How do I get a raise?

* How do I not get fired?

Beyond those common desires are a constellation of more personalized that is specific for each salesperson and the cohort they target (I'm somewhat of an idealist in that I believe people are quite often strongly driven by meaningful non-capitalist, non-realist desires).

In any case, when you're working in enterprise sales, what you have to realize is that, regardless of what the desire is, what your corporate champion is "buying" is a way for them to achieve their goals and only incidentally what is good for the company, where your product is merely a proxy to accomplishing this.

Of course, companies also know this and anyone who has owned a P&L immediately recognizes that the sum of all things everyone wants far exceeds the resources of the balance sheet, thus, some selection process needs to be put in place to allocate scarce resources.

Your corporate champion is ideally far more aligned with you against the company than they are with the company against you and your job is to figure out how to win this selection battle together.

The core insight though, is that people are actually astonishingly bad at performing on this and it's actually quite easy for an outside sales person to become a subject matter expert for 3 core reasons:

1. Any employee usually only ever has a sample size of 1 whereas you have a broader peek into how this has happened across a range of companies industry wide.

2. Any employee, only a minor part of their job involves interfacing with outside parts of the firm responsible for allocating resources whereas you treat this as a core competency.

3. For any person, it's always easier to advise a 3rd party on what to do than to practice the same actions yourself.

What this means though, is that, as an enterprise salesperson, you should understand that your core value comes from developing subject matter expertise in how to help people in your industry get promotions, get raises and avoid getting fired and the product you're representing at the moment is merely the avenue through which you enable that to happen.

The best salespeople I've ever met always share a common core value that they deeply care about making sure everyone around them is getting rich with the faith that some of that money eventually reflects onto them but that's not what drives them. That's why so many immigrants and children of immigrants make such great salespeople, they've seen the material difference wealth has made on their circumstances and they want to spread that opportunity to others.

This is what I advise Founders who start Enterprise focused businesses. Fundamentally, you should be thinking about how do I get someone to VP/Director/Line Manager/Tech Lead 2/3/5 years earlier than if my product doesn't exist and how do you breathe this passion day in day out.
