L-Theanine has a noticeable effect when I drink my morning coffee, it totally eliminates the jittery effects and smooths it out.

I've tried a lot of CBD products and some work VERY well (Feals, Soul) and some might as well be gummy bears (Cornbread Hemp). I generally disbelieve "internet" PR claims as well, but the two I mentioned are legit.

I'll eat 3 Feals gummies or 1 Soul "Out of Office" quad, and it rocks me. (M, 40's, 6', 170lbs).

I live in a liberal part of California.

No one has said anything to me about driving a Tesla, and I doubt anyone will.

I know a few folks who have ruled out a tesla because of Elon, but the realize that a car and the ecology around it is more than its CEO (or whatever he is).

I know many more folks who have bought a new one.

Your opinion is inconsistent with the vast majority of economists and financial analysts.

The government has the taxing power to remedy any shortfalls. If the country were truly in bad shape financially, we would have to pay much higher interest rates and our bond rating would below the highest grade there is.

I don’t know who you’re listening to, but whomever they are, they’re not very well informed, or at the very least, they’re at odds with the smart money.
A site [1] mentions that student visas (F-1) may alter the protections of the first amendment, but doesn't go into any specific detail. Legal or not, if you're deported, it's ruinous, and forcing people to try to litigate against it is a practical win. Sounds like we need anti-SLAPP laws to protect us from the feds now...

I’m a Jack Bogle diehard index investor, but the idea that most economics and finance is BS strikes me as deeply incorrect. Not everything is long term retirement investing. Most car and home owners in this country would be SOL without modern finance, for starters, and I suspect a great many vacations would simply never happen if credit cards didn’t exist.

Even renters these days live in buildings largely financed by either banks, reits, private equity, etc and underpinned by securitization.

And when it comes to business lending the entanglements with corners of financial services that look nothing like mutual funds only get more extensive.

Just because you don’t know much about it doesn’t meant it’s nonsense.
> Freedom of speech would suggest that I could be pro-Hamas if I wanted to be

Short answer, yes [1]. The First Amendment prohibits the Congress from passing a law that abridges the freedom of speech. There is no visa exception. That would make such visa terminations unlawful. (If a student on a visa got themselves arrested, that’s a separate matter.)

On a strategic level, this should give us hope. Trump is back to his first term arrogance and chaos. If State had moved quietly and decisively, damage could have been done before it was too late. The Palestinian cause is only a little bit more popular than USAID; in the end, there wouldn’t have been a broad fight. Instead, they got caught by Axios [2]. So we can get injunctions ex ante.

> It is strange to discuss L-theanine with vitamin D as one has nothing much to do with the other.

That's the idea, vitamin D was used as a placebo. They bought vitamin D supplements rather than cellulose because the supplier sold both L-theanine and vitamin D and the pills looked (nearly) identical.

Thanks. Clace is built for teams to be be able to deploy internal tools (Streamlit/Gradio etc). That use case requires some extra features (OAuth/Auditing/Declarative config etc). Kubernetes with ArgoCD plus IDP seems to have become the default solution, which is overkill for such use cases.

The Hypermedia based app support was added to be able to build a management dashboard for Clace itself, without going down the SPA route. It made sense to expose that for end uses to be able to build their own apps.
Revoking a visa has to cite a legal reason for doing so, such as ineligibility or criminal activity.

The article isn’t specifically about the USA (the word “American” appeared once in “American English” when explaining the name Pi-hole). The CharlesW comment doesn’t mention the USA. The nik282000 comment says NextDNS is a U.S. company so U.S. government will have access to the data, it never said it’s only a concern for American users. I don’t know where you got the idea that this thread is specially about the USA. In fact, I assume the nik282000 comment is mostly for non-American users.

H3's algorithms involve some intricate maths, but the library itself is conceptually simple. Check this page out for some really fun and neat ideas: https://www.redblobgames.com/grids/hexagons/.

Uber internally had extensive research on what kind of grid system to use. In fact, we started with S2 and geo-hash, but H3 is superior. Long story short, hexagons are like discretized circles, and therefore offer more symmetry than S2 cells[1]. Consequently, hexagons offer more uniform shapes when we compose hierarchical structures. Besides, H3 cells have more consistent sizes in different latitudes, which is very important for uber to compute supply and demand of cars.

[1] One of the complications is that H3 has to have pentagons to tile the entire world, just like a soccer ball. We can easily see why by Euler's characteristic formula.

As someone who actually likes the time changes, as part of the annual cycle of stuff that changes and lets the year "breathe", I just want to set up and knock down my favourite anti-DST argument:

"Why should we move the clocks off from (close to) the solar-noon standard? If people want to get up and go to work earlier so as not to 'waste sun', they can do that, and just coordinate it, no need to change the clocks."

I hear this argument frequently, every year. But here's the thing, I've got a great way to do that coordinating. It's called daylight saving time. DST is our way to collectively, without every single business having to change their posted office hours and every school having to adjust their starting times and every club having to adjust their meeting times, agree to move all times one hour earlier/later so as to better line up with the sun. DST itself _is_ the mechanism by which we collectively make that shift.

And it's a good idea.
Hey! Good to talk to you.

Sorry, I was AFK for several hours.

Thank you for the offer, but I don't think Yao should be featured yet.

Edit: I guess I'll answer your questions anyway.

> So Yao has a delineation between safe and unsafe code, correct?

Correct. However, Yao's "unsafe" will actually be separate files, written directly in an LLVM-like assembly (Yvm in the repo). That's how it will be harder to use.

> Does "safe" in Yao have the same (or stronger) set of guarantees as Rust (i.e. no memory safety if all necessary invariants are upheld by unsafe code, and boundary of safe-unsafe code)?

Stronger.

First, Yvm (Yao's assembly/unsafe) is made specifically for structured languages, and it will still do bounds checks by default. Yes, there will be ways of not doing bounds checks, of course, but even in "unsafe," bounds checks will exist.

Second, Yao and Yvm are both explicitly designed for better formal verification. [1] This includes user-defined formal properties.

> Does Yao guarantee memory safety in the absence of unsafe blocks?

Yes.

> does the condition+restart system in Yao fall under the safe subset of the language?

It's still being implemented (hence why Yao should not be featured), but it will be a part of the safe subset. That is a guarantee; I will completely redesign Yao if I cannot fit conditions and restarts in the safe subset. But I am confident that they will work as-is because I implemented a prototype in C that is safer than C itself.

> 1. Are the types of restart functions passed down to functions that are called?

Not directly. My C code uses, and Yao will use, what I call "context stacks," an idea that comes from Jonathan Blow's Jai.

These are more useful than just restart functions, but there is explicitly one context stack for restart functions, per thread. Registering a restart function means pushing it onto the context stack.

Then, when an error happens, the context stack is walked backwards until a restart function handles the error. If no function handles it, the context stack for the parent thread is walked (starting at the point where the child thread was created), and so on until some function handles it.

I push a default restart function at the root, so errors will always be handled.

> 2. If the type information is not passed, and conditions+restarts are part of the safe subset of Yao, then how is resumption logic checked for type safety and lifetime safety? Can resumptions cause run-time type errors and/or memory unsafety, e.g. by escaping a value beyond its intended lifetime?

This is one of the craziest parts of Yao: it will have the capability to be generic over types at runtime. In addition, Yao has something like Go interfaces or Rust traits. What it has is more powerful, though.

The end result is that errors will actually be interfaces, and everything will be type checked at comptime, but be memory safe.

I hope this answers your questions.

Everything Musk has done in the past few years has proven he is not to be believed or trusted in any way.

He is a destructive moron. He is the gremlin on the wing of the plane. Between Tesla, Twitter, and now the Federal Government he might have fired more people than anyone else in history.
I agree, although it also depends on the context. If a page needs to fetch lots of data and takes 3 full seconds to load, the middle case (4x improvement) makes it go from an amount of time where you glance at your messages to on par with the average javascript-laden website we're used to anyway (except in this case it's legitimate loading time). If, however, we're talking about most pages, that are mostly static and just fetch some article contents and author name from the DB in 2 milliseconds... yeah, it can be 10x faster and nobody cares
> most economics and finance is BS strikes me as deeply incorrect

But it’s true based ok numbers. All of these “professionals” as a whole are not beating passive investors.

Modern finance isn’t the reason we have credit cards. Those were common 30+ years ago.

Additionally, someone taking a vacation they can’t afford that they finance via credit cards is not an example of success.
Turmeric, but I think it's only some suppliers?
Musk behaved the EXACT same way when he took over Twitter and wanted to move out of one of the 3 main data centers they used. Actual experts told him it would take a year so he instead impulsively hires basic movers to rip the servers out and was surprised at how many things this broke. He said "I didn't realize how many places that data center was hardcoded". Except people absolutely told him that.
I've mentioned this in another comment but the Freetube [0] client for YouTube has settings that let you hide pretty much every distraction apart from the video. You can even exclude videos in your search result if they contain a set phrase (great for avoiding political bait). I know there are extensions that do all these things but I find this to be a nice all-in-one solution, and the UI is more responsive too. (It does suffer from expiring sessions and the like though.)

If they are far enough away from the star that's correct. i.e. if the star was a point source.

But if they get close they'll slow down by interaction with the atmosphere of the star. Which is more likely than random chance because the star is attracting them.
Yes this sort of tolerance building is the norm. There’s somewhat reduced cross-tolerance so you might alternate lsd and psilocybin.

AI CTO
Small startup teams often juggle a lot of tools and responsibilities with very few people. We have AI coding assistants, project tracking tools, and plenty of DevOps automation – but what we lack is a unifying layer to coordinate them. As a result, the technical founder/CTO still ends up manually managing each tool and process, which is cognitively taxing and error-prone. I’m exploring the idea of an AI orchestration layer that acts like a mini “AI CTO” or project lead. The concept: it would delegate tasks to multiple AI agents specialized in different roles (coding, testing, DevOps/SRE, project management, etc.) and coordinate their output to keep the software development pipeline flowing. For example, you could describe a feature or goal, and the orchestrator breaks it down: the coding agent writes code or unit tests, the SRE agent sets up necessary infrastructure or monitors performance, the PM agent updates your task board and timelines – all under the guidance of a central AI that understands the project’s priorities and checks the work. The aim is to reduce the cognitive load on the human CTO by having the AI system align all these tasks, catch routine issues, and maybe even flag decisions for human review when necessary. My questions to HN:
Usefulness: Would such a system actually be useful for a small startup team, or would it end up adding more complexity than it removes? If you’ve been a lone developer or CTO, can you imagine this making you more productive, or just getting in your way?
“AI CTO” – right framing or not?: Is calling it an “AI CTO” the right framing? Or would you think of this more as an advanced AI project manager/dev assistant rather than a true CTO replacement? (I’m cautious about the term – not trying to replace strategic roles, more about automating execution and coordination.)
Failure modes / pitfalls: What do you see as the failure modes or risks of this approach? For example, cascading errors if one agent misinterprets something, difficulty aligning AI decisions with the nuanced context of business needs, trust and verification issues, etc. In what scenarios would an AI orchestrator break down or require heavy supervision?
Prior art / similar attempts: Has anyone here tried to build or use something like this? There’s been talk of “Auto-GPT” and other multi-agent systems – if you’ve experimented with those in a dev workflow, what was your experience? What worked or didn’t?
I’m looking for technical critiques and insights. Even high-level skepticism is welcome (e.g. “this won’t work because X”), as are pointers to any research or products in this area that I should know about. My goal is to understand whether this concept could genuinely help startup engineering teams or if there are fundamental reasons it would fail. Thanks! Excited to hear your thoughts and experiences.
Ooopsie. Yes, I was talking about the browser. I'll read about compatibility mode, but I'm not sure why would I need to enable something like this on an WebKit browser on MacOs while Safari is doing great.
I studied it, have an advanced degree in it, worked in it for years. The theory is 90% nonsense. There is a large difference between 90% nonsense and 100% nonsense. The basics of microeconomics and the basics of finance are fine. Some of the stuff around real option theory is good. Anything about "advanced asset pricing", "advanced portfolio theory", practically all upper level macroeconomics and a good chunk of microeconomics, is absolutely nonsensical. And the worst type of nonsense - sounds good, doesn't work.

The vast majority of finance is basic loans (as you call out). There is no 'sophisticated' financial theory involved, it's very basic.

The financial theory required to make corporate loans is also very basic - the complicated part is understanding the business so that one can make decent projections. For example, to make oil and gas loans you better have a very good understanding of oil and gas reservoirs, the engineering involved in drilling, pumping, fracking etc. Hell, the legal side of a corporate loan is more complex than the finance part. Even securitization is quite straightforward - there are just a lot of numbers.
Vitamin D3 is not a placebo at all. It 100% promotes energy quite quickly even though it takes much longer for the body to convert it to the active form. Also, its mental effect is distinctly different from that of L-theanine, like day and night. For these reasons, it's not a great candidate for comparison with L-theanine.
