Close, but not quite. The general tendency for large nuclei to be less stable is correct, but for any given size, there is something of a optimum proton/neutron ratio that is most stable, and either adding or removing neutrons will reduce the half-life (minus various complications involving magic numbers etc.). At the very neutron-rich end, isotopes tend to spontaneously and rapidly emit the excess neutrons, and at the very neutron-poor end they will spontaneously shed protons to stabilize themselves. If you map these boundaries on the table of nuclides, you get the so-called neutron and proton driplines, respectively, which delineate the isotopes that, as GGP put it, can be reasonably agreed to exist. If you are interested in this stuff, [1] is a decent overview.

This paricular article is about mapping out isotopes close to the proton-drip-line in a heavy synthetic element, with the particular result that excited states can be more long-lived than the ground state of the isotope. This again is nothing particularly new. Generally excited states are short-lived, but there are many known examples of inversion, with the most extreme being a rare, naturally occurring, isotope of Tantalum: Ta-180m. The ground state Ta-180 has a half-life of 8 minutes, while the excited state is de facto stable, with a still unknown half-life in excess of 3*10^17 years [2].

> you will need to have 67 democrats as senators

I think impeachment is a long shot. We agree in that Trump’s popularity is what gives him power. If he lost it, one woudln’t need 67 Democratic Senators on Capitol Hill, the GOP would save itself. It’s just difficult to imagine what Trump could do to fuck up that badly.
SICP is not the horse's mouth in this matter, and doesn't purport to be. It's presentations are designed to suit its pedagogical aims, not to build up a historically accurate Lisp.

AI-generated child sex abuse images targeted with new laws in UK
I haven't pursued this yet, but having a tendency to listen to music without lyrics, and being generally fastidious, I'm interested in doing so. But I'd only do so if able to tailor the music toward my preferences. I think there's a lot of potential for a program that lets the user (easily) tailor AI generated music and I'd heartily dive into such an application. If it allowed to select an instrument (or set of), and perhaps a genre (as a starting point), that would be pretty neat.
There are, I think two questions:
1) will we have enough energy to do “split water and use H2”?
2) how is the energetic ratio between “compress and move the H2” on the one side and “filter CO2 out of the atmosphere, split that and integrate the H from 1) into the COs from here”?

I think 1) will come with a storage and movement demand anyhow (at least short term and for steel making), so there is a feed source for funding (that is not just state subsidies) for the former. Whereas 2) fundamentally requires the CO2 removal from the atmosphere. And I do not see a clear funding source (besides state subsidies) for _that_ problem. (So I think we may mostly disagree on the existence of “spare CO2” as a cheap feeding source)

Do you have any comparison of the physical limits of energy required for those processes? As I said, a lot of my thoughts still rely on “intuition” and that’s always reasonably dangerous. But for me “move H2” sounds like a solvable problem. Yes probably not for longterm, cheap and pressurized storage, but that’s also not required. If you have “pressurized and short” and “longterm and plentiful” that would be fine too.
Show HN: Chrome extension to run GenAI models in browser
Hi all, I open sourced my toy project that runs Generative AI models LOCALLY in the side panel of a Chrome extension.

The Chrome extension uses Transformers.js to run models under the hood. I've integrated and tested these models so far.

* LLM: Llama 3, Phi 3.5, Qwen 2.5, SmolLM2

* Reasoning: DeepSeek R1 (On an M1 MacBook, DeepSeek R1 (1.5B) runs at ~30 tokens/sec)

* Multimodal LLM: Janus

* Speech-to-Text: Whisper

If you're interested in, you can download the extension from chrome web store or clone my github repository.

* chrome web store https://chromewebstore.google.com/detail/private-ai-assistan...

* github https://github.com/tantara/transformers.js-chrome

* demo https://www.youtube.com/watch?v=MSCDdFG5Lls

It's my first react project. Feedback is always welcome!
Pretty much my point.

I should look into the terms/conditions for that.
It is quite amusing how an order that changes language is an existential attack when done by a rightist, but just a request for basic common courtesy when done by a leftist. I'd be much more angry about this if I didn't remember the past decade of language policing.

(And no, I don't want to misgender trans people. But I do want leftists to finally be honest that pronouns and the associated language games were and are an attempt to change people's thoughts by hacking their language. Maybe if we all agree that this order is bad, we can remember that when the next pendulum swing comes around.)
OpenVINO is quasi-abandoned, nobody uses it, Intel barely puts any effort to improve it.

In terms of tooling there's scoop[0] which does a lot of the capture part of what you're thinking about. The files it creates include request headers and responses, TLS certificates, PDF and screenshots and it has support for signing the whole thing as proof of provenance.

Overall though I think archive.org is probably sufficient proof that a specific page had certain content on a certain day for most purposes today.

Not surprising. While there has been some movement in the positive direction (like Syria - though we still have to see how this will last) we see more movement in the other direction like Hungary, Poland (in a lesser extend), etc. No doubt in small part due to social media, allowing fake news and dumb simplicity to spread much more easily beyond the local social bubble.

> This censorship is much more petty

It’s in the same vein. The government is removing information so it can act impunitively against certain people. The people getting harmed by these policies are, in the end, poor and marginal. If you’re already lucky enough to be rich in America, you’re probably getting much richer in the next four years.

ALL THAT SAID, if I were advising Trump (I’m not) and asked to be Machiavellian, I’d say his single priority right now is the budget. Create as much confusion in the public space as possible so your surrogates in the House have the room they need to manoeuvre. (Also keep an eye out for CBO’s gutting. It’s a real check on Trump inasmuch as it lives outside the executive and determines what can be passed on party lines with reconciliation.)

This is a weird way to look at it. There's a shifting of incentives towards less "dangerous" topics. But "dangerous" just means citizens have decided research involving these terms is generally not the highest ROI for taxpayer funding. No one's going to face the wall over private research.

I was thinking we've got a set up for that. Trump tariffs, Musk wanting to cut 2trn in spending, and stock markets at record highs due to the AI bubble.

Been hearing from colleagues about a flood of applicants, and within those, a large majority have no business applying (i.e. no visa support, not in appropriate city, not right general skills, fake person).

So how early in the process:

1) initial resume upload & pre-screening questions
2) second pass for more info
3) initial discovery call (5-30 minutes)

You realize you're saying this in the same thread as the US government demanding a mass retraction of submitted scientific paperwork to facilitate the mass censorship of words and science they don't like, yeah?

It might be in many cases, but not every language it seems has explicit sodium support. Golang for example, has this not-widely-used wrapper (https://github.com/jamesruan/sodium) maintained by some random guy which might not be desirable to use for a variety of reasons.
Apple Digital Masters indeed recommends no clipping. But the program is based on Apple interviewing the process that to-be-certified mastering engineers use. There is a way where you can pass the interview, get certified and then decide that clipping sounds better/louder/whatever and the file will still get the ADM stamp.

I don’t blame you. They are very careful to shift the boundary a little bit each time, to keep most frogs not aware that the water is slowly coming to a boil. They distract also with the pure idiocy like blaming DEI for plane crashes and impossible decreets which are immediately shot down by the judge.
You are free to believe what you want to believe and to seek out media that will tell you what you want hear.

How does one identify the proper "equivalent" in a given programming language that doesn't have 1st class sodium support?
Fragments of it I found look promising. Thank you!
Good point. LLMs can be treated as "theories" and then they definitely meet falsifiability [1] allowing researchers finding "black swans" for years to come. Theories in this case can be different. But if the theory is of logical or symbolic solver then Wolfram's Mathematica may be struggle with understanding the human language as an input, but when evaluating the results, well, I think Stephen (Wolfram) can sleep soundly, at least for now

Considering the audience: Get whatever x86 (arm if you have a more enthusiastic vibe and don't mind some independent research) hardware, install your Linux/BSD distro of choice (it doesnt need to be a "router" distro in case youre already handy with some other base system. setting up from vanilla can be easier than getting into idiosyncracies of openwrt/pfsense/etc) and configure it yourself. It will be valuable and useful even if your ISP requires their own gateway in the middle. Get 2 of whatever it is so you have a spare/staging ready if it becomes necessary later.

I think the emperor's new clothes is not a fitting comparison at all. Everyone could see the emperor was naked, they just thought they were the only ones. As soon as there was a second voice confirming what they saw, the illusion crumbled. But trump voters are so far off the deep end, the smoke screens so elaborate, that they _actually_ see the fine garments.
Alright that's fair, in this thread there's not much reason for people to encourage learning it so it wasn't a good example to use. Thank you for helping people to learn more about it.

That being said, the sentiment around rolling your own crypto that I see in the rest of internet in general still strongly discourages any kind of curiosity, intentionally or not.

In other places where it's discussed and in the comments on this thread which are not a direct response to aspects of the blog, you get mostly the same kind of response.
There is no reason to believe that browsers do it just fine if you have evidence for the contrary.

Improving BWT is great!

In my view, improving "long range" compression has the biggest potential. There are many, many algorithms and implementations for very short range (huffman, arithmetic, ANS) and short range (LZ, BWT), but not that much research has gone into "long range" yet. There's deduplication, and large-window LZ / BWT.. but not much more yet. What is missing is efficietly (and with little memory) finding similarities on multi-GB data sets. I think sorting by similarity would help there. Or did I miss research in this area?

The problem with these weaknesses is that they are different in each human being. For me listening an mp3 is like a sanding an ear, while some don't even hear the difference between it and a live performance.
This is more of a reddit problem. They don't allow true discourse anymore and this is the consequence. It's harder to have a rational debate about a difficult topic while still courting advertisers. So it became an echo chamber and a bunch of people left. That's what you're describing.
> But, the key thing here is that if the programmer wrote *(p+1) = 10; print(q[0]); it is entirely reasonable and legal for the compiler to optimize that to *(p+1) = 10; print(0); Because the abstract model says that stores to one object can not alias another object.

If the programmer wrote that... but that's not what the programmer wrote. The programmer wrote *(char*)iq = 10 which was provably (!) equivalent to both *(char*)(uintptr_t)q = 10 as well as *(char*)(uintptr_t)(p+1) = 10. That means the compiler can't just replace it with the latter while ignoring the former -- it must carry the aliasing constraints implied by the former into the latter.

> However, in this case, the optimizer transformed a legal, well-formed construct into a illegal construct and then optimized as if it was always a illegal construct. Focusing on directly preventing such transforms and why such transforms should be illegal (pointing out the legal -> illegal thing they enable) minimizes the changes needed to the model.

I see where the confusion is.

You're missing this sentence: "I am using C syntax here just as a convenient way to write programs in LLVM IR." The intermediate transformations you see there are not C code.

You're looking at the compiler as "optimize C to faster C, then codegen". In which case you can blame step 2 (the replacement of *(char*)(uintptr_t)(p+1) with *(p+1)) as the violating culprit, due to the aliasing rules.

Which... would be fine if you view it that way, I don't mind too much if you do.

But I'm looking at the compiler as "generate IR for C, then optimize the IR, then codegen" (which is closer to what LLVM does), in which case the "*(p+1) = 10" you see in the 2nd optimization step isn't C code anymore, it's LLVM IR that the author tried to transcribe in some made-up language that superficially resembles C! You can't really say "this is a legal transformation" anymore because it's not the C code anymore, it's just some internal compiler gibberish that someone tried to display with a imitation-C syntax to make it easier to read. The aliasing rules no longer apply there, because it's not actually C... it's LLVM IR.

Which is why I said "q is never written to" (step 3) is the violation. Because as I saw it, step 2 was fine, because it wasn't C, so it didn't have the aliasing semantics of C. In fact it would be illegal for the compiler to transform the original program into that and continue to treat that as equivalent C.
Tariffs are not extortion; they are lawful taxes on imported goods. Every country can levy tariffs on any other country; they aren't unique to the US. Your personal feelings about Donald Trump don't change these facts.

The hyperbole on HN has been ridiculous lately. Get it together, folks. The US doesn't owe any other country cheap prices and the US also reserves the right to raise income in any lawful manner.
Assuming that you populated the channels correctly, which I believe you did, I can only think that this issue could be related to the motherboard itself or RAM. I think you could start by measuring the single-core RAM bandwidth and latency.

Since the CPU is clocked quite high, figures you should be getting are I guess around ~100ns, but probably less than that, and 40-ish GB/s of BW. If those figures do not match then it could be either a motherboard (HW) or BIOS (SW) issue or RAM stick issue.

If those figures closely match then it's not a RAM issue but a motherboard (BIOS or HW) and you could continue debugging by adding more and more cores to the experiment to understand at which point you hit the saturation point for the bandwidth. It could be a power issue with the mobo.
That's a good thing but due to D syntax it is very intuitive and pythonic due to the default GC, in addition to the UFCS feature that I've mentioned compared to C with its agrarian syntax. That's the main reason we have C shell scripting in the form of csh with more intuitive syntax for example foreach loop that D has already supported [1].

But if you insist, D now supports and can compile C language that you can perform using rdmd [2].

Indeed, the terms "biologically male" and "biologically female" have been described by activists who are not at all aligned with Trump as "trans-phobic" and a "TERF dogwhistle" so it's strange to see these two groups suddenly agreeing with each other over something.
Yes. Trump gets away with shit because he’s deeply charismatic and his most ardent supporters think he’s the next coming of Christ. Elon has some super fans but not like that.

All this also isn’t occurring in a vacuum: the GOP is full of highly ambitious people who won’t want the competition for their own run.

GOP lost house and senate seats they could have won behind another candidate. Trump is useful to the party until he’s not. Elon is of zero use at all to the party.
