DEMO concept sketches are completely obsolete at this point. It's not going to look anything like this.

They're based on the state-of-the art from about 2005. Since then, a lot of improvements happened. A more realistic power plant design is going to use a thinner center column (because of better superconducting magnets), resulting in a smaller cryostat volume. Possibly high-TC magnets.

It can also be made more compact, if neutral beams can be used to suppress some plasma instabilities.

>This is actually the first I’ve heard about anyone actually actively using it

I've been reaching for Claude Code first for the last couple weeks. They had offered me a $40 credit after I tried it and didn't really use it, maybe 6 weeks ago, but since I've been using it a lot. I've spent that credit and another $30, and it's REALLY good. One thing I like about Claude Code is you can "/init" and it will create a "CLAUDE.md" that saves off it's understanding of the code, and then you can modify it to give it some working knowledge.

I've also tried Codex with OpenAI and o4-mini, and it works very well too, though I have had it crash on me which claude has not.

I did try Codex with Gemini 2.5 Pro Preview, but it is really weird. It seems to not be able to do any editing, it'll say "You need to make these edits to this file (and describe high level fixes) and then come back when you're done and I'll tell you the edits to do to this other file." So that integration doesn't seem to be complete. I had high hopes because of the reviews of the new 2.5 Pro.

I also tried some claude-like use in the AI panel in Zed yesterday, and made a lot of good progress, it seemed to work pretty well, but then at some point it zeroed out a couple files. I think I might have reached a token limit, it was saying "110K out of 200K" but then something else said "120K" and I wonder if that confused it. With Codex you can compact the history, I didn't see that in Zed. Then at some point my Zed switched from editing to needing me to accept every change. I used nearly the entire trial Zed allowance yesterday asking it to impelement a Galaga-inspired game, with varying success.

In the US, mineral rights are land use rights. It allows you to extract minerals, which has priority over some other land use rights. You are responsible for restoring lower priority use rights only to the extent you have deprived them. You are not responsible for any deprivation of use rights you did not create, which existing mines would be.

I have owned water, mineral, grazing, and other rights in the western US in environments where these were all considered valuable. YMMV.

You must be well impressed with Gough Whitlam and Eddie Mabo et al then.

> to fix the sins of those who are long since dead

A good number of land right issues and acts of racism began with those long dead and continued forward under the actions of generations that followed, perpetuated in some form by some still living.

In a US context there are still current acts of administration that impact native title and rights to reservations that are current and contentious.

> But it's not out of question for US to be competitive in a few generations.

i think it is - as in, if the need ever arises in a war, the loss would be far sooner than the time required for "competitiveness".

That is, of course, this new war is going to play out the same as the last one. But as with all history, it only rhymes.

I’ve been intrigued by recurse for a long time because the alums I’ve met are all very impressive.

But when I think about applying, I worry that it’s just tapping into my addiction to external validation and credential-seeking rather than just learning something on my own.

Or… that’s what I tell myself because I’m not nearly as bright as the recursers I’ve met

In the 2037 timeframe, modeling trends doesn’t matter as much as looking at the actual players. I think odds are good because you have at least 4 very well funded groups shooting to have something before 2035: commercial groups including CFS, Helios, TAE, also the efforts by ITER. Maybe more. Each with generally independent approaches. I think scientific viability will be proven by 2035, but getting economic viability could take much longer.

This is a weirdly conspiratorial idea to my eyes. Not because people don't have unsavory hidden motivations that they give good excuses for, but because this doesn't really seem to confer any benefit.

The benefit of wealth is your capacity to spend it. If they don't spend it in order to give it away on a future date, they have lived their lives without it.

You can say that they are selfishly maintain optionality while they are alive, but that's a less biting critique, I guess.

This is a straightforward consequence of how continents are defined by various cultures.

In Anglo cultures, there are seven continents, with a distinct North and South America, and Europe and Asia.

In Romance cultures, there are six continents, with a single America, and a distinct Europe and Asia.

In some eastern European cultures, there are six continents, with a distinct North and South America, and a single Eurasia.

Who’s right? Who’s wrong? It’s kind of meaningless; it’s not like these definitions are based on some semi‐objective characteristic like counting tectonic plates. In the Anglosphere, nobody is actually confused about whether “America” refers to the country or the continents. Canadians don’t appreciate being called Americans, and (in my experience) Mexicans don’t desire it either. If one wants to refer to North and South America together, there’s a perfectly normal way to do so: “the Americas.”

USian, aside from its lack of euphony and its general connotation of being used by know‐it‐all scolds, is particularly silly since the existence of two countries named “United States”—two North American countries named “United States”—means it’s just as ambiguous a country name as “America” is claimed to be.

Even though I consider estadounidense silly (why aren’t people of Estados Unidos Mexicanos considered estadounidense, exactly?), I use it when speaking Spanish, because that’s the way people say “American” in Spanish. I don’t explain to Spanish‐speaking people how ignorant they are for using such a silly, ambiguous word. One wishes the same courtesy were offered in the other direction!

The problem with buses is that utilization is very low. Most buses, most of the time, run near empty.

This also significantly i creases their overall passenger mile GHG emissions.

Hybrid buses and CNG probably make sense. But I doubt, fully electric buses make sense: as long as dispatch-able power (ie your marginal producer) is a thermal plant you get 60ish% thermal efficiency at best minus transformer and transmission losses.

A bus engine for use in a hybrid can be made more than 40% efficient (miller cycle, high compression, high octane CNG, full throttle PWM operation, etc).
by mousethatroared | 2025-05-09 02:34:40+00:00
Its not obvious to me that EV buses (or any EV vehicle, frankly) make sense. [1]

Hybrid and CNG make a lot of sense though.

[1] Run the math and hybrids come ahead of EVs in personal vehicles for GHG emissions. For buses it would be more skewed in favor of hybrids.

> at least in the original implementation of this protocol (cjdns) there was already a tiny bit of proof of work happening in address generation.

It's just a 1 byte search, completely negligible from the performance standpoint. They look for a public key that has the SHA hash that starts with 0xFC, to indicate that it's not global IPv6 traffic.

I don't think it's possible to solve this, without either making a centralized addressing authority, or involving non-trivial amounts of real money via some blockchain.

the mprotect API could have been designed more like malloc() - ie. you don't protect a preexisting memory range - instead the API returns a new memory range with the protections you've asked for, possibly copying a load of data into it for you incase you asked for a readonly range.

And that 'copy' might be zero-overhead remapping of the original pages.

> I personally like the "open source Xyz" because I instantly know what the product is supposed to do.

But that assumes that you're already familiar with the non-open-source software referenced. I've never used Cursor so I have no idea what it can or can't do. I'm pretty sure I would never have discovered Inkscape if it had consistently been described as an “open-source Illustrator” as I've simply never used Adobe software.

This title is incorrect. It's why GIPR agonists and antagonists lead to weight loss. GLP-1R may be involved, but these papers are about GIPR.

Also, pedantic side note, in this instance, the hormone (GLP-1, GIP) are not the things being drugged, but rather their receptors are (GLP-1R, GIPR). Therefore the terminology is incorrect, it should be GLP-1R agonist/antagonist (except that as mentioned, that's also incorrect because wrong protein).

Ever wonder why Spain was a civilized province while Gaul and Germany remained hostile frontiers for the Roman republic? Just take a look at the map in this article. Spain originally belonged to Carthage. Large parts of Rome's empire were civilized, not by Rome, but by Carthage and the Phoenicians.

I think you're right that the Phoenicians deserve more credit, as does Carthage. There is yet hope more of their history may come to light. We're unlikely to uncover records on the organic media the Phoenician alphabet was tailored for, but Mesopotamian cultures were contemporaries of the Phoenicians and we're discovering/translating new cuneiform tablets all the time. Entire Mesopotamian cities remain to be discovered, and some significant ones that we know of are likely buried beneath modern settlements.

We may never get the Phonecian's story from their own perspective, but we may yet get a better picture of them from people who didn't have a vested interest in erasing their history.

> I'm not interested in paying 10x as much and still having limits. It would have to be 10x as useful

I don't think this is the right way to look at it. If CoPilot helps you earn an extra $100 a month (or saves you $100 worth of time), and this one is ~2x better, it still justifies the $100 price tag.
Show HN: Raw Binary Program Analysis Tool
by bootbloopers | 2025-05-09 02:41:11+00:00
I built a tool for analyzing raw binary programs (programs without an ELF, PE, Mach-O header) to determine the file offset that the program begins at and the load address the program is mapped into memory at. The tool can also do find the instruction set architecture for common platforms. I put a lot of effort into making it as easy as possible to run, and there is a quick start script that takes a single argument: the absolute file path to a raw binary program file.

Charity just means helping someone. Do you think no one in Chad needs or is offering help? And if you don't know anyone in Chad who's in need of charity then...why do you want to do charity in Chad?

It seems that our notion of charity has been warped in such a way that it somehow doesn't count unless it's some enormous large-scale mission carried about by Charity, Inc for the benefit of some group of people far away. It's all very abstract, and that just creates room for fraud or exploitation.

Paying off a local person's debts or putting their child through college will probably be far more impactful and meaningful than sending your money off to some giant organization.

Yes, IMO why DoD wanks about replicator and drone hellscape, when PRC doing the same thing. Everyone is trying to sink each others entire surface fleet... but those with industrial base (even if degraded) can reconstitute faster, i.e. PRC navy is "only" 3m GTs... about 1 month of current production, 2 months for all of USN @4.5m GT (yes 9 women can't make a baby in 1 month), but just to give scale of how "small" modern navies, including USN, are relative to modern shipbuilding.

I also doubt US built ships will ever be globally commercially competitive vs east asian builders (or whoever comes next), but the point is modern ship building has gotten efficient, and it's feasible for US to reshore enough ship building for domestic needs. I think for American's sake, it's illustrative to stop nostalgical pine for US WW2 ship building prowess, because it's really meagre compared to modern ship building scale.

Also be aware that if US WW2 shipping buildig dial was set to 10, PRC set the dial to not just 11, but 50. The consolation is it's very feasible for US to move dial from current 2 back to 10, perhaps even 20. And for US strategic interests (and ego) that's probably enough.

Maybe that's our ultimate disagreement. I think the difference between composition and inheritance matters a lot. It changes how we break our software into modules. It sounds like you think of inheritance as being fundamentally the same as composition "with slight differences". Although even you admit that "Our brains cannot handle the complexity [of inheritance]". If that's true (and I think it is), the difference is surely more than skin deep.

I agree about nesting. But nesting matters, because it forces us to design components which make sense in isolation. As a result, composition encourages - and in many ways requires - better modularity in code. Inheritance does not. Base classes are often poorly conceived, poorly specified grab-bags of state and functions. They lead to hard to understand, hard to follow code.

Earlier in this thread you insulted my intelligence. You said this:

> Don't ever tell me that programming for 30 years is a reason for being correct. It's not. In fact you can be doing it for 30 years and be completely and utterly wrong. Then the 30 years of experience is more of a marker of your intelligence.

I'm curious if you'll still back the argument you've made here after you've been programming for 30 years too. You're clearly already suspicious of how and why inheritance makes code harder to understand. I suspect in a few years, you'll come around to my point of view on this. But I'd love to know if I'm wrong.

It was published in 2024. There is still discussion happening: https://mailarchive.ietf.org/arch/msg/oauth/Ce0HH05eKFKh6P0F...

I admit, I was surprised by how slowly standards moved. I published a comparison of OAuth2 and OAuth2.1 a few years ago and thought it would have been published by now.

On the other hand, I'm not in there helping, so can't complain too much.

Good, good, good! I am so glad that there are blockers in place against this kind of malicious shit. Do not ever interpose a machine where a human touch is required. These kinds of situations cry out to Heaven for a licensed, certified, trained human being. If you try to cram a machine into the pipeline here, you are asking for trouble. I am thankful that Google has at least attempted to put a stop to that kind of horrible disgusting perversion of machines.

Just anecdoting, a couple weeks ago I asked my first question about the definition of `width` in CSS and how it pertains to minimum size calculations.

It was immediately closed as off-topic with 3 votes. One commenter asked "can't you figure that out using developer tools?"

It was eventually reopened, but I'm never asking a question there again. FWIW one of the governing web bodies essentially says "If you have technical questions, ask them on SO and not here" - I take this to mean that they don't care if you are able to answer your question, they just want you to go away.

>But also kind of lulz that SKR peacetime ship building is like 7x more efficient than US during WW2.

there is huge difference between building 1 x 500k GT container ship and 50 ships x 10k GT

About future sea based fighting - Ukrainian sea drones armed with Sidewinders have already shot down Russian helicopters and one Su-30 fighter (may be even 2).

https://www.twz.com/sea/aim-9-sidewinder-armed-ukrainian-dro...

A small sea battle between such a drone and a manned Russian fast light seacraft https://www.youtube.com/watch?v=djKIu4gC_sQ The drone lost this time, yet one can clearly see potential if the drone were also armed with a small anti-ship missile or just a radar guided machine gun (or they may be organized in a pack where each drone carries one type of weaponry while still staying small and agile). The poor Russian Marines had really hard time and that against just one remotely controlled drone - when the drones become fully autonomous with more suitable weaponry, and attacking as a pack instead of alone, humans wouldn't stand a chance.

I’m ruminating about making some very cheap and simple anti drone systems - the idea is how to respond if say in a small regional theater an adversary launches a million of drones. Don’t see many working in that direction while it should be a large market soon.
