My beginners journey: http://www.robertames.com/blog.cgi/entries/so-you-want-to-le...

From "Noad" there's a Spanish Study that is on track with your goals: https://youtu.be/p_YHVf_pan4

Flamenco (traditional) uses a unique rhythm called a "compas", 12 beats, and "should" be practiced with dancers stomping the counterpoints.

Flamenco Guitar Basic Techniques (Juan Serrano)

Flamenco Guitar Method (Gerhard Graf-Martinez)

...it's a loooong road, and the climax of it has you buying a new (specifically for flamenco) guitar, as it resounds better in a crowded dance hall or theater.

You have to decide to learn to play by ear, by tab, or by notes, and as I mentioned in my blog post, you have to struggle through a long period of time "nobody thinks I sound like anything worth a damn".

As an adult student, you may end up in a recital going up against 11 year olds and thinking to yourself "Damn! Their twinkle twinkle little star is kicking my versions ass!"

It's a loooong road, I've been an off and on student for ~15 years, mostly self-taught, classical with Spanish/Latin influences.

Antonio Briebesca, Paco de Lucia, Johannes Linstead (Para La Habana), Gypsy Kings (of course), Rodrigo y Gabriela are all (non-flamenco), and some are slightly more modern flavor of the direction your question was probably in.

Shoot for the stars and you'll eventually be able to bang out a few decent tunes after a year or two. Good luck!

But see, it works both ways. If a judge can unilaterally block the president from exceeding his authority, a judge can equally well block the president from exercising his authority. (There is no magic black letter printing on executive orders that is within his authority and red letter printing for those that exceed it. In fact, this is exactly what these court cases are about.)

So either a judge can block orders that exceed the president's authority and orders that are within it, or the judge can block neither.

I guess the task is to design an experiment to test the error between phase inferred from intensity in a digital camera by Huygens-Steiner and a barycentric coordinate map And far more expensive photonic phase sensors.

Is (framerate-1 Hz) a limit, due to the discrete derivative being null for the first n points?

Fortunately this article explained the implications of said breakthrough; "Physicists use a 350-year-old theorem [Huygens-Steiner] to reveal new properties of light waves" https://phys.org/news/2023-08-physicists-year-old-theorem-re... :

> This means that hard-to-measure optical properties such as amplitudes, phases and correlations—perhaps even these of quantum wave systems—can be deduced from something a lot easier to measure: light intensity.

IDK what happened with wave field cameras like the Lytro. They're possibly useful for face ID, too?

"SAR wavefield". There's a thing.

From https://news.ycombinator.com/item?id=32819838 :

Never played with OCaml, but I spent the past few days learning about F# (my understanding is that it inherits a lot from OCaml). Tooling seemed great: I used JetBrains Rider; VSCode and Visual Studio are also options. Support seemed great: good official docs; good book choices. Ecosystem seemed great: entire .Net class library.

I’m been on the JVM for 20+ years, but an opportunity came up to leverage some of my other experience to get some CLR work… and I dove in.

It's a shame, but in a glass-falf-full sense the fact that this planet is our little boat in the ocean and all that we got is also a quite helpful focusing reminder and scope constraint.

That the stars are beyond reach might be depressing, how aggresively we are gambling our little boat is on the other hand actively scary and perhaps the dominant limit on humanity's effective reach.

> “Give me your tired, your poor, Your huddled masses yearning to breathe free, The wretched refuse of your teeming shore.”

So, I assume that you know that's a poem by someone who was engaged in pro-immigrant propaganda? And the entire reason that Lazarus was engaged in pro-immigrant propaganda was because she was advocating for Jewish refugees from Russia...who weren't exactly welcomed.

Basically, your proposition that it was era of free immigration is historical revisionism. There's a whole island out in front of the Statue of Liberty where the primary purpose was finding reasons to turn immigrants away.

(Castle Garden was established in the 1850s, and the history extends way before the nativist laws you're referring to in sibling comments [1])

That’s exactly how constitutional challenges have always worked. In our system, different circuits can interpret federal law differently until SCOTUS resolves the split. It’s not ideal, but it’s how precedent gets built.

Nationwide injunctions didn’t “force” consolidation. Often, they often blocked it.

We need to follow the process as designed.

This ruling restores pressure to actually appeal and get clarity at the appellate or Supreme Court level.

I’ll admit it’s slower but it’s slower by design. Less patchwork this way.

In ocaml you would rather do something like this: let x_power_8 = (let a = x*x in let b = a*a in b*b);

a, b variables are just used for computing x_power_8, you don't need them outside of this scope. I think the point of the exercise is to use variable binding, though I agree the website doesn't explain much

> They have to be loud enough to be heard through hearing protection.

It's kind of a nit-pick, but this is not really true.

Very approximately, you will perceive a sound if it is above your threshold of hearing, and also not masked by other sounds.

If you're wearing the best ear defenders which attenuate all sounds by about 30dB, and you assume your threshold of hearing is 10dBSPL (conservative), any sound above 40dBSPL is above the threshold of hearing. That's the level of a quiet conversation.

And because your ear defenders attenuate all sounds, masking is not really affected -- the sounds which would be masking the reversing beepers are also quieter.

There are nuances of course (hearing damage, and all the complicated effects that wearing ear defenders cause), but none of them are to the point that loud reversing noises are required because of hearing protection -- they are required to be heard over all the other loud noises on a construction site.

> The utility of having a backup beeper or any noise making device on that site is thus zero.

The inverse square law says otherwise; on site the distances will be much more apparent.

That should be calculable.

Orbital mechanics, orbital period, and minimum determinable arc of JWST.

Though another thought is that doppler might also reveal velocity, if a spectrum could be obtained. Since the system is nearly perpendicular to the Solar System (we're viewing it face-on rather than from the side), those shifts will be small.

> There's a whole island out in front of the Statue of Liberty where the primary purpose was finding reasons to turn immigrants away.

The 14th Amendment was adopted in 1868.

Ellis Island was not opened until 1892. The shift in approach stems from laws in the 1880s and 1890s; again, decades after the 14th.

The full timeline is quite conclusive. https://en.wikipedia.org/wiki/Birthright_citizenship_in_the_...

> any of 700 district judges could unilaterally block the president from exceeding his authority

Not at all. Whether or not the president is exceeding their authority, a judge could block it nationally. It's not like lower court rulings haven't been overturned before.

And the bigger issue is "judge shopping". Want to block something nationally? Just find 1 of 700 judges who will rule the way you want, and file in that district.

I didn't say you don't build stuff: that diatribe is just very clearly someone speaking as an academic.

You're presumably intelligent enough to realize the writer here wasn't trying to define "understanding" from first principles.

And from a more practical mindset you'd hopefully realize it's not a useful expenditure of energy for them or the reader to enter the tarpit in the first place.

-

So far, if I extract the one practice-minded point you've touched on, it's much narrower: how the lack of generalization intersects with parties making claims about "PhD levels of intelligence" based on narrow benchmarks.

That's the conversation that can be had without resorting to strawmen or declaring an impasse on the language used to describe these systems until we've found the terms that satisify all other disciplines in addition to this one.

Maybe you've spent your life absorbing Knuth's essence and know better than me, but he strikes me as pragmatic enough to not fall for that trap either.

He even refers to LLMs as X% intelligent machines after he decided having someone else use ChatGPT on his behalf was the best way to evaluate it, right?

> if people mostly disagreed with the elites

People agree on most things for sensible reasons. There’s no country where people are going to be ok legalizing murder in all situations. Similarly we aren’t going to randomly convert street signs to cuneiform or other language nobody speaks etc.

> You’re overestimating how much people care about any of this stuff. I’m in a blue state and I hear almost nothing about it other than from some overly empathetic people on facebook. The “protests” recently were tepid and nearly all elderly liberals with nothing better to do.

> A big chunk of the country really wants mass deportations, and for the most part, folks in the broader left don’t care much to oppose it

I’m not talking about one specific issue here but how much people in general dislike what’s happening. That includes Democrats, Republicans, and Independents.

I know multiple hard core Republicans since Gerald Ford who now dislike winning elections only slightly less than they dislike loosing them. As one put it ‘Democrats do a better job of fucking balancing the budget, what I am doing?’

I've been playing classical guitar for a bit. A teacher who specializes in that style is your best option, but teacher quality can vary quite drastically and can be hard to manage if you're a busy professional. For an online, asynchronous resource, https://classical.guitarcorneracademy.com has been great for along with occasional check-ins with an online teacher.

I wonder instead if what is being described here comes from a conflation of drag and maybe something from the BDSM world with trans? I think it does describe the experience of people who live a life in which they feel if not undesirable, then at least ordinary, who have an costumed highly sexualised alter-ego which they inhabit a kind of performance which put makes them a focus of attention, sometimes of desire, and sometimes in a position of power (not these are not exclusive) that is very different from their ordinary lives.

Partisan organizations are running to judges late on Friday nights, "randomly" getting judges who issue a TRO before the government even is informed of the lawsuit let alone respond. We are talking about blocking the executive from action before any argument is made in the merits. That's not at all consistent with co-equal branches. If they kept this up, Trump would rightly echo Andrew Jackson "Well, John Marshall has made his decision, but now let him enforce it."

Just to add to this, we know have XXSLT which solves a lot of the original problems with XSLT.

Just to frame this people, imagine a JSON-based programming language for transforming JSON files into other JSON files and the program is also in JSON and turing complete. Now imagine it's not JSON but XML! Now any program can read it! Universal code, magic!

The idea behind XXSLT is now, we actually have a program whose job it is to specify a program. So we have a XML file which specifies a second XML file, which is the program, whose job it is to transform XML to XML. As we all know, layers of abstraction are always good, and common formats such as XML are especially good, so what we have now is the ability to generate a whole family and diverse ontology of programs, all of them XML, all of them by and for XML. Imagine the compiling with your favourite XML-based compilation chain!

Nope. Wrong. That's the new facility. Castle Garden started in the 1850s:

> The 14th Amendment was adopted in 1868.

Yes, and? I'm not debating the legality of whatever the current administration is doing. I'm just telling you that you have the history wrong, and that there's a deep irony in quoting Lazarus as some kind of "good old days", when she wrote the poem as a form of advocacy for immigrants.

Somehow this makes me think of "water activity" levels in foods, where a stabilized/preserved food might actually have a decent amount of water in it, but it's been bound up in such a way that it's not immediately bio-available for bacteria to access.

It messes with our intuition about what kind of food is before us. (Not that my intuition for things like calorie-content was ever very good to start with.)

If you have worked or lived in China, you will know that Chinese open-source software industry is a totally shitshow.

The law in China offers little protection for open-source software. Lots of companies use open-source code in production without proper license, and there is no consequence.

Western internet influencers hype up Chinese open-source software industry for clicks while Chinese open-source developers are struggling.

These open-weight model series are planed as free-trial from the start, there is no commitment to open-source.

All snark aside, ways to learn (already listed) include teachers, books, videos and the most difficult of all your ear. If music theory isn’t your bag, pick a song and learn to play the first phrase. Then the next phrase, then the next. That’s how they did it in the old days. One song at a time. One bit at a time.

If you want shortcuts to playing guitar enough to impress many, you can skip (some) theory and learn a few chord shapes. To play like the masters will require dedication to craft impossible for most. I applaud your efforts.

In this scenario the precedent has already been set in the 5th, why would the Supreme Court hear it again?

The 9th has nothing to do with an immigration hearing in the 5th, the individual’s personal history is irrelevant here.

Matter of Rahman, 20 I&N Dec. 480 (BIA 1992) seems to cover this. (IANAL)

Oh I read it, and I disagree with your analysis. Sotomayor makes some decent points in favor of nationwide injunctions when she deigns to engage in legal arguments, but the case against them is very compelling.

The textual case is pretty much completely against them, and if you prefer a consequentialist analysis their drawbacks are well documented across the political spectrum. I will say Barrett's time as a professor can mean her opinions are highly technical in their procedural analysis and she's not as strong of a writer as other members of the court.

This very opinion is also an example of something that Thomas has beat the drum about for some time and it later becomes a majority opinion.
by unsnap_biceps | 2025-06-28 01:45:29+00:00
So the purpose of the judiciary branch is to interpret the laws. If a judge rules that the government is violating the law, you want the government to continue to be allowed to violate the law until the legislature convenes a hearing and rules and then what? The judiciary branch was able to rule on punishment for violating the rules, fines and jail time and what not. You would push all that to the legislature as well? Or would the legislature run a hearing and then ask the judiciary branch to pick the punishment and then have the legislature apply it?

I just don't understand how you expect this to work unless the point is to make the judiciary branch entirely pointless (for government level check and balances).

I do wonder if the advantages of the separate compilation model are being realized. Like I can understand having the semantics of a separate compilation model (and I think you could keep those without actually implementing with them?) but if the compiler really did just pull in what it needed and nothing more something tells me we could see massive perf improvements from dependencies.

I suppose a lot of the coherence checking still "needs" to happen, but how I would love a "--i-dont-care-about-coherence-in-dependent-traits" flag or something. I know I'm missing a lot

This is just like the pokemon experiement: putting next token models that were never trianed to be agents in space, as agents in space. And its failing the same ways

Barring halicinations, all of the fialures are related to reinforcement learning. It cant keep its optimization function in mind long enough to not maximize revenue and minimize cost. It cant keep state in mind well enough to manage inventory, or gauge that its losing money.

And the things anthropic is prescribing is falling right into the bitter lesson. More tooling and scaffolding? A CRM? All thats doing is putting explicit rulesets to guide the model. Of course that shows results in the short term, but it will never unlock a new evolution of AI, which managing a store or playing pokemon would need.

This is a great experiment, the right takeaway from this is that a new type of base model is needed, with a different base objective than the next word/sentence prediction of LLMs. I dont know what that model will look like but it needs to be able to handle dynamic environments rather than static. It needs to have a space state and an object. It basically needs to have reinforcement learning at its very foundation level, rather than applied on top of the base model like current agents are
Ask HN: How JVM works? I am developing Similar Virtualization
by Hashex129542 | 2025-06-28 01:49:48+00:00
My company has been assigned the task of developing a general-purpose virtual machine, similar to the JVM, to run our own custom bytecode and scripts. I understand how the JVM works internally, but I don’t understand

How a entry `.class` file is recognized as a unique application on macOS and having separate doc icon? How the class files communicates Java Runtime Environment?

PS: First I thought to develop a complete new OS like environment, means the VM considers the byte code as document & it'll have own doc, application gallery, install/uninstall system.

I actually have some insider info on this. While it sounds like in theory all you have to do is take your existing lawsuit and add the additional step on certifying your class, that option isn't available for the vast majority of legal challenges. In the history of the ACLU they have had less than ten cases where they could have been converted into a class action. As a real life example the "trans women being moved to men's prisons" case isn't eligible to be made into a class action. Tangentially related if you want to see a painfully explicit example of "the cruelty is the point" read that EO. Even if you're someone who broadly agrees with the order it's a lot.

Unfortunately "the set of people who are affected by this law" doesn't define a class.

Yes, and my point is that this isn't even about the traditional political issues and tribal squabbling. I'm a libertarian. I was hating on the "deep state" before it was cool. Still, as an American it's time to circle the wagons - anyone with half a brain should be dead set against Trumpism. We've been taking the rule of law for granted, and we really need to stop.

Furthermore, I think it's bad to continue calling this movement "conservative", as it helps disguise their aims as business-as-usual rather than the sea change towards destruction of the American experiment. At best they used to be conservative. Then they got angry that the leaders they would choose kept selling them out and that fundamentalism didn't produce effective results, so they gave up on their constructive values and fell into blind team allegiance. Now they're just reactionary/autocratic/authoritarian/fascist.

"web services protected by Cloudflare have been throttled by Russian Internet Service Providers (ISPs)"

I'm an ISP. It is not us. We face specific obligations due to our licensing. There are two primary requirements we must adhere to:

1) We have to filter URLs, domains, and IP addresses from the RKN blacklist. Failure to comply can lead to fines and the loss of the license.

2) We must purchase DPI hardware from a state-affiliated supplier. This equipment is installed on every internet access channel we manage, and we are required to hand control over it to a contractor associated with a state agency (RKN). The state refers to these DPI as ТСПУ (Технические Средства Противодействия Угрозам), which are purportedly designed to counter threats to Russian infrastructure. However, their current use primarily targets the bandwidth throttling to foreign services, aiming to encourage the adoption of locally-controlled alternatives. Because this DPI implementation falls under national security concerns, the state does not disclose its specific objectives or operations. No court approval is necessary for these actions. This lack of transparency allows state representatives to lie with a straight face to the public and the press regarding the true reasons behind the diminished performance of services like YouTube and Cloudflare. They always promote the use of local services instead, blaming foreign services for lacking compliance with local laws, proper technical support, and adequate resources.

The ISPs are unable to countermeasure this practice and even fail to provide their customers with a consistent explanation not contradicting the official position.
