Looking at partisan actors at face value is just going to lead you to a trap.

Literally from the article: "News reports, presumably based on DHS statements, described Quiet Skies as a “Biden-era” program even though its largest expansion came in 2018 during the first Trump administration. And according to the TSA’s press release last week:".

There's no way a program expanded during Trump1 just disappears in Trump2. Everything Trump2 is doing is just a continuation from Trump1.

> In the short-run, from what I see, firms are trying to play-up the operational efficiency gains they have achieved.

The thing is all of this is getting priced in, and will be table stakes for any business, so I don't see it as a big factor in future success.

As I've said here, LinkedIn, and one a few other places, the businesses that will succeed with AI will be those who can use it to add/create value. They will outcompete and out-succeed businesses that can't move beyond cost cutting with AI[0].

[0] Which might not last forever anyway. Granted there are a decent number of players in the market, thankfully, but this wouldn't be the first time tech companies had hooked large numbers of individuals and businesses on a service and then jacked up the prices once they'd captured enough of the market. It's still very much in the SV and PE playbook. SolarWinds is a recent example of the latter.

> why do we need all these unit tests in the first place?

The same reason we've always needed them:

1: They prevent regressions. (IE, bugs in features that were shipped and already working.)

2: They are very easy to run at the push of a button in your IDE. (But in this context the LLM runs them.)

3: They run in CI. This is an important line of defense in making sure a pull request doesn't introduce a bug.

Now, depending on what you're writing, you might not need unit tests! Perhaps you're trying to get a minimum viable product out the door? Perhaps you're trying to demo a feature to see if it's worth building? Perhaps you're writing a 1-off tool that you'll run a few times and throw away?

But, understand that if you're writing an industrial-strength program, your unit tests help you ship bug-free software. They allow you to do some rather major refactors, sometimes touching areas of the codebase that you only lightly understand, without needing to manually test everything.

(And, to keep it in context,) your LLM will also have the same benefits from this tired-and-true process.

It's possible to cast the lifetime away. It's also easy to wrap it in a safe API: https://docs.rs/recycle_vec/latest/src/recycle_vec/lib.rs.ht... (libstd will likely add something like this).

However, the other issues they mention hit some well-known limitations of Rust, which don't always have a simple satisfactory solution. It's a valid criticism.

With a bit of `unsafe`, it's easy to force through self-referential structs incorrectly and violate exclusive ownership/aliasing rules (that's UB, in Rust!). Sometimes such code can be reorganized to avoid self-referential structs. With enough `unsafe` dark arts it's also possible to properly handle some self-references. However, in general it's typically a false positive in the borrow checker's model, and an annoying limitation.

I'd pick a nit on the phrase "sorry to hear you and <company> parted ways"

To me, "parted ways" sounds like a mutually-agreed separation.

I'm not sure what's better, maybe "sorry to hear we won't be working together anymore" but really, unless they were a pretty close friend I probably would not say anything. It just comes across as "sucks for you" while not-so-subtly drawing attention to the fact that I still have a job.

There is a program called CT-Art[1], that uses "motifs" to train tactical sight for these sorts of things. Instead of next-move type puzzles where the moves are obvious, it gives you a game position several moves out from the targeted tactic, so you learn to recognize the conditions to be able to steer the game toward the tactical position. I think in it's current iteration it's broken out into separate courses or something but the older programs (v2 or v3 that I can vouch for) were really great for improving in these kinds of areas.

Nope, the purpose of a Synology unit is to be about as complex as a toaster. Put it on the shelf, plug it in, make sure auto-updates are enabled, and forget about it until it sends you an email in 5-10 years that one or more drives is full/failing. I bought a synology almost 10 years ago and it's been purring away in a closet somewhere and never causing problems the entire time.

If you want a device to tinker with, this is the wrong product for you.

I built an AI Navigation and Task Assistant called InsteinAI which let businesses add AI Powered actions to their websites, what that means for businesses is that their customers can now have an agent that retrieves real-time data and takes actions on their behalf, which significantly increase customers experience because users no longer have to worry about navigating, finding features, or getting stuck, because the agent understands the website and acts for them. InsteinAI is built using computer use model from Anthropic and OpenAI Operator.

Yeah, I feel like people have this idea that the EMH is 'economists think markets are perfectly efficient' when really it's 'under these idealised conditions a market should approach perfect efficiency' and any real market is obviously not going to be perfectly efficient, but ones that get closer to those conditions should be more efficient.

(And looking at how traders work, it's all about finding a strategy that no-one else has found and executing on it. Once two competitors with similar resources know the strategy, it ceases to be particularly profitable, which to me seems to be pretty in line with the EMH)

The 68k was unique in that it included in its design the ability to act as a Harvard Architecture processor (where instructions and data have separate signal pathways rather than being together in the same address space [1])

It did this via the function code pins, which signaled differently depending on whether the chip was requesting instructions or data, in supervisor or user mode. No other consumer-grade chip had this as far as I know.

Sega's System 16 was also 68000 based (as was the Megadrive/Genesis), but I don't know anything about their protection scheme.

I'm fine with it. I love dogs, and I find suggestions that LLMs may achieve sentience or become conscious either laughable or abhorrent, depending on how serious the person is who's making them.

It's still OK to use dogs as an analogy. In this case the analogy is to unreliable tools, and dogs are unreliable tools.

I don't find "stochastic parrot" offensive as an analogy, even though it's got parrots in it.

The math looks suspicious to me, or at least how it is presented.

If, as stated, accessing one register requires ~0.3 ns and available registers sum up to ~2560 B, while accessing RAM requires ~80 ns and available RAM is ~32 GiB, then it means that memory access time is O(N^1/3) where N is the memory size.

Thus accessing the whole N bytes of memory of a certain kind (registers, or L1/L2/L3 cache, or RAM) takes N * O(N^1/3) = O(N^4/3).

One could argue that the title "Memory access is O(N^1/3)" refers to memory access time, but that contradicts the very article's body, which explains in detail "in 2x time you can access 8x as much memory" both in text and with a diagram.

Such statement would require that accessing the whole N bytes of memory of a certain kind requires O(N^1/3) time, while the measurements themselves produce a very different estimate: accessing the whole N bytes of memory of a certain kind requires O(N^4/3) time, not O(N^1/3)

Maybe it that's an apt analogy in more ways than one, given the recent research out of MIT on AI's impact on the brain, and previous findings about GPS use deteriorating navigation skills:

> The narrative synthesis presented negative associations between GPS use and performance in environmental knowledge and self-reported sense of direction measures and a positive association with wayfinding. When considering quantitative data, results revealed a negative effect of GPS use on environmental knowledge (r = −.18 [95% CI: −.28, −.08]) and sense of direction (r = −.25 [95% CI: −.39, −.12]) and a positive yet not significant effect on wayfinding (r = .07 [95% CI: −.28, .41]).

https://www.sciencedirect.com/science/article/pii/S027249442...

Keeping the analogy going: I'm worried we will soon have a world of developers who need GPS to drive literally anywhere.

A good faith person who was also informed would be aware that this is basically a criticism of Romney-era neocon policies, and that agenda is no longer the animating force of the GOP (and was soundly defeated despite the wishes of the great and the good of the party establishment). In the far-right circles I frequent, the sentiment is, basically, "Triple, quadruple, quintuple the national debt, and crash the economy, if that's what it takes to halt immigration and have a country again, rather than an economic zone."

It was not free-market sentiment that propelled Trump to the WH.

Separately from "accurate", I would also argue that if the improvement you are proposing is slim or difficult to distinguish from other ongoing ambient improvements - then perhaps you shouldn't try to bring it up as a stand alone project. It's not worth it. "Slim" is not enough impact. You could bring it up as part of a package of other improvements - like those generated day in, day out by a methods or build group. They should be the ones championing small ongoing improvement - and they have an umbrella "do what you can" budget for that.

I remember trying "call <my wife's name as in my contacts>" a few years ago and Google Assistant cheerfully responding with "calling <first Google search hit with the same name>, doctor". I couldn't believe it, but back then, instead of searching my contact list, it searched the web and called the first phone number it found. A few years later (but still pre-Gemini), I tried again and it worked as expected. Now, some time ago, post-Gemini, it refused to make a call. This is basically the first most obvious kind of voice command that comes to mind when wondering what you can do with the assistant on your phone and it's still (again?) not working after years of voice assistant development. Astonishing.

> Most camera sensors already detect in the IR range, you just need to remove the filter. I've done it, works great and pretty fun

It's not the same IR you'd need for military purposes, you're seeing a tiny percentage of the IR spectrum, and it's the most useless. That's why any semi decent military tier system costs 50k+ a pop. Civilian tier scopes are 1k+ and pretty shit, you won't see anything smaller than a human more than 1km away.

Alternatively, apparently you can make a true vector display by steering a laser.

Here's a DIY example: https://www.youtube.com/watch?v=bdo3djJrw9o

I suppose you could even point that at a screen with phosphors on it for a more CRT-like effect. (Maybe you'd need a different kind of phosphor since you'd be exciting it with visible light rather than with an electron beam, though.)

by glitch003 | 2025-10-08 18:31:44+00:00
Vincent lets users safely grant apps/agents limited, revocable permission to use their wallets. Think “OAuth for crypto actions”: you define scopes (e.g., “rebalance stables on Aave up to $1k/day”), users approve, and your app runs within on-chain guardrails. Non-custodial. Built with Lit Protocol's decentralized programmable signing.
Show HN: Twoway, a Go package for HPKE encrypted request-response flows
by 1268 | 2025-10-08 18:31:45+00:00
Hey HN,

I'm Willem from Confident Security, we've built CONFSEC, a provably private AI inference engine. Today, we're excited to open-source twoway: https://github.com/confidentsecurity/twoway

twoway is a Go package that makes it easy to implement secure, encrypted request-response flows. It powers CONFSEC's blind prompt handling, ensuring no one, not even us, can see client requests.

We built twoway on Cloudflare's circl/hpke, it uses Hybrid Public key Encryption to implement two flows: - A one-to-one flow where a sender communicates with a single receiver. This flow is fully compatible with RFC 9458 Oblivious HTTP (OHTTP), and the chunked OHTTP draft RFC. - A one-to-many flow where a sender communicates with one or more receivers. Similar to the Apple's PCC's request flow.

Other features include: - Compatibility with any transport, twoway deals with just the messages. - Chunked messages. - Allows for custom HPKE implementations for specialized needs like cryptographic hardware modules.

Our README has clear examples to get you started, all you need to do is go get and try an encrypted "Hello world" exchange.

Our team will be popping in to answer questions, we'd love to hear your feedback.

Cheers! Willem

I think you have a strong argument here, but there's a problem of deeper and widespread rot at play.

The reason Uber can get away with pretending it's just a "connector" is because the entire tech ecosystem has been allowed to normalize that kind of control without accountability.

Look at Apple and Google: they take a 30% cut on every sale and ban any competing payment systems. That's the same pattern - absolute gatekeeping disguised as "market facilitation."

Our regulators have become so complacent that this behavior is now seen as the default way digital markets work. The problem isn’t just Uber's misclassification; it's that the entire platform economy is built on pretending these companies are neutral middlemen when they're really gatekeepers.

The main reason why the US was supportive is because they wanted to break open the coal market as well as the German near monopoly (together with the Swedes) for high grade steel at the time. It was a purely selfish reason, and not because the USA wanted Europe to unite. The hypocrisy is obvious given the numerous US monopolies at the time and various attempts to insert US standards into EU practices to give US companies a leg up. Funny enough, they tried the same in Iraq. EU dependency on the US is bad, but fortunately finally (and thanks to the most unlikely person) we are realizing this. But repairing it is going to take a lot of time and will be costly. We also have to guard not to become similarly dependent on China, whose motives are no better.

https://european-union.europa.eu/principles-countries-histor...

The USA does not even rate a mention, though it probably should have, that's a bit of EU revisionism afaic.

More on this in Wikipedia:

"The United States was not officially part of the treaty negotiations, but it was a major force behind the scenes. The US High Commissioner for Occupied Germany, John McCloy, was an advocate of decartelization and his chief advisor in Germany was a Harvard anti-trust lawyer, Robert Bowie. Bowie was asked to draft anti-trust articles, and texts of the two articles he prepared (on cartels and the abuse of monopoly power) became the basis of the treaty's competition policy regime. Also, Raymond Vernon in the State Department (of later fame for his studies on industrial policy at Harvard university) carefully reviewed successive drafts of the treaty. He stressed the importance of the freedom of the projected common market from restrictive practices.

The Americans insisted that the German coal sales monopoly, the Deutscher Kohlenverkauf (DKV), should lose its monopoly, and that the steel industries should no longer own the coalmines. It was agreed that the DKV would be broken up into four independent sales agencies. The steel firm Vereinigte Stahlwerke was to be divided into thirteen firms, and Krupp into two."

As for the Holy Roman Empire, no, that was not what I had in mind but since you are arguing in bad faith all over this thread I don't think it is worth my time to continue the discussion, even if I think that in principle we agree. It has been noted before that just like here you are stating a lot of things without actually aiming to make a point and you are repeating things that are objectively false in order to confuse the discussion, and things that are true but that are besides the point and not worth the contest because of the ridiculous out-of-proportion weight you assign on some details. I have no clue why you are doing this but I also simply don't have the energy for it.
Show HN: Quant, the AI stock trading analyst
by mceoin | 2025-10-08 18:32:45+00:00
Today we're releasing Quant (https://sourcetable.com/quant), an AI analyst that connects to 600+ exchanges with 1000+ built-in analysis tools. Andrew, CTO, has a background building software at hedge funds so we put his knowledge and experience into this application.

The core idea: if you already know spreadsheets, you shouldn't need to learn Python/R or set up complex infrastructure to do serious quantitative analysis. One way to think of Quant is a low-cost Bloomberg Terminal alternative.

What's inside: Portfolio optimization (including Dalio's risk parity approach), Monte Carlo simulations for backtesting Sharpe ratio, Black-Scholes, and risk analysis Real-time data from 10,000+ sources via connectors. Direct execution to platforms like Robinhood AI assistants that can explain concepts and analyze your positions

The AI layer is particularly useful for learning - it can walk you through why certain strategies work, explain the math behind models, or help debug your analysis. We're offering a free tier to start, and we'd genuinely love feedback from folks here who've built their own trading systems or struggled with existing tools.

Happy to answer questions about the architecture, data pipelines, or design decisions.

I've heard Einstein's General Relativity described that way.

Special Relativity was not such a big breakthrough. Something like it was on the verge of being described by somebody in that timeframe — all the pieces were in place, and science was headed in that direction.

But General Relativity really took everyone by surprise.

At least, that's my understanding from half-remembered interviews from some decades ago (:

Wellll...

LLMs are not actually intelligent, and absolutely should not be used for autonomous decision making. But they are capable of it... as in, if you set up a system where an LLM is asked about its "opinion" on what should be done, it will give a response, and you can make the system execute the LLM's "decision". Not a good idea, but it's possible, which means someone's gonna do it.
