So the assumptions are:

1. An agent can analyze another system, even a complex one including other agents, using quantum mechanics

2. This assumption of consistency, that the predictions made by different agents using quantum theory are not contradictory

3. If an agent’s measurement says that the coin toss came up heads, then the opposite fact — that the coin toss came up tails — cannot be simultaneously true.

But isn't everything you measure in quantum mechanics probabilistic? E.g. the article itself gives the example of measuring a polarized photon at 45 degrees giving 50/50 chance of each outcome

So all 3 assumptions have an issue:

1: even if you can analyze it, you're analyzing just probabilistic data anyway.

2: why expect consistency if your results are probabilistic?

3: I thought the whole concept of superposition was both options being simultaneously true

What am I missing here that makes this paradoxical?
Show HN: We Launched Our Testnet (DigitalSPX: ETFs to Tokens)
by adi-io | 2025-07-07 14:19:16+00:00
Hello everyone,

I'm Adi, one of the co-founders of DigitalSPX (https://www.digitalspx.com).

We are building a platform that allows users to convert their stablecoins into ETFs of their choice. Our goal is to create a community-led platform where users can vote on which ETFs they want to see added.

Our smart contracts are deployed on BASE, with an architecture that ensures transparency and security. We are excited to announce the launch of our testnet: users can now buy and sell a testnet version of the Digital SPY ETF, similar to a paper trading account.

Our primary focus is on serving people in underserved regions, making it as simple as possible to exchange USDC for ETFs and vice versa.

We would love to hear your feedback and are happy to answer any questions you may have. If you’re interested, please check us out!

Thank you!

The confusion may come from the various spelling conventions in the numerous loan words. In many of the counterintuitive cases, you could imagine a more phonetic spelling. The tradition has been to preserve buffet as is, instead of rewriting it as, "buffay".

The distinction is there. English can be used phonetically. We prefer to preserve the heritage of various loan words instead.

> There's no credible evidence Spotify built their company and business on pirated music.

That's a statement carefully crafted to be impossible to disprove. Of course they shipped pirated music (I've seen the files). Of course anyone paying attention knew. Nothing in the music industry was "clean" in those days. But, sure, no credible evidence because any evidence anyone shows you you'll decide is not credible. It's not in anyone's interests to say anything and none of it matters.

> Maybe I've just got unlucky in the past, but in most projects I worked on a lot of developer time was wasted on waiting for PRs to go green.

I don't understand this. Developer time is so much more expensive than machine time. Do companies not just double their CI workers after hearing people complain? It's just a throw-more-resources problem. When I was at Google, it was somewhat common for me to debug non-deterministic bugs such as a missing synchronization or fence causing flakiness; and it was common to just launch 10000 copies of the same test on 10000 machines to find perhaps a single digit number of failures. My current employer has a clunkier implementation of the same thing (no UI), but there's also a single command to launch 1000 test workers to run all tests from your own checkout. The goal is to finish testing a 1M loc codebase in no more than five minutes so that you get quick feedback on your changes.

> make builds fully hermetic (so no inter-run caching)

These are orthogonal. You want maximum deterministic CI steps so that you make builds fully hermetic and cache every single thing.

> But does anyone else get embarrassed of their career choice when you read things like this?

What specifically is embarrassing about it? None of these questions seem especially hard, and they're exactly the sort of problem that I face on a daily basis in my work. They're also fairly discussion based rather than having one silly trick answer (like the XOR trick that came up recently here). The whole point of an interview is to check that the candidate can do their job. What would you propose instead? We don't bother to interview and just cross our fingers and blindly hope they'll know what they're doing?

I can only assume that the real reason for your objection is that your job actually doesn't involve solving problems like these ones. Well, that's fair enough, and then I'd expect the interview for your position to look different. But why would you assume that there are no jobs that really need these skills?

Your comment about using a CSV file for a database seems unrelated. Maybe I missed the real point of your comment?

The pricing is a little on the higher side. Working on a performance-sensitive application, I tried Mercury and Groq (Llama 3.1 8b, Llama 4 Scout) and the performance was neck-and-neck but the pricing was way better for Groq.

But I'll be following diffusion models closely, and I hope we get some good open source ones soon. Excited about their potential.

I see what you mean. I think you should stick to one form and learn by difference or you could quickly get lost.

"ll" in standard spanish is a strong english "y".

However, in spanish argentinian from the area of Buenos Aires (but not the argentinian Córdoba, which sounds more like colombian spanish) it is "sh", being that s something like a mix in-between of "j" and "s" + h as in "she" but the sound is a bit different.

Without being able to record some sound I cannot express it better but I am sure you can find something around. Javier Milei, the president, has such an accent.

> Is windows even usable on laptops still?

Is Linux even usable on laptops still? I've got a number of machines that still seem to fail to wake from sleep on even most recent and common distros.

Is Mac even usable on laptops still? I've had a lot of coworkers and friends with Macs still run into hot bag situations often.

> Between the waking from sleep to check notifications

Its rarely ever actually Windows that's causing the issue. Almost always crappy drivers and crappy hardware that causes the wake. Disabling allowing wake from sleep on whatever crappy hardware is causing the sleep problems is almost always the answer.

I recently spent some time trying to figure out why my Lenovo Legion Go was waking from sleep. I could put it to sleep and it would almost always wake up within an hour. There's a nice utility in Windows to help analyze power patterns on the system called powercfg which will give you a good report with powercfg /sleepstudy . Turns out one of the USB4 controllers was using a stupid amount of power while asleep which would cause the system to wake. Disabling that USB4 controller to wake the system from sleep meant it wasn't even partially awake and thus stopped using so much power and would not cause the system to wake. Now the device has been asleep for many hours and hasn't woken up once unexpectedly. It also is getting less battery loss sitting on the desk asleep than it had previously.

I guess I should have specified financial benefit.

You wouldn't pay someone else to insure a common vegetable, because it is so low cost that if it turned out to be bad, you would just buy another one (or have bought extra as your insurance).

When you buy from Walmart/Target/Amazon/Best Buy, they will try to sell you insurance for a $30 toaster or other cheap appliance. Again, most people will not buy this because they will believe the appliance will work sufficiently long or that the warranty process will be too time consuming, or otherwise decide that just quickly replacing the cheap appliance with another is the preferred way to insure it.

The insurance seller is a business and has to earn more than what they pay out for claims (or at least to make payroll if it is a mutual insurance company). Otherwise, they are going to lose money over time and go out of business. If you financially benefit from it, then you are either lucky, or had an information edge over the insurance underwriter.

Of course, if you get peace of mind from buying insurance, and count that as a benefit, then most insurance is beneficial in that case.

"Mr. Torres, who had no history of mental illness that might cause breaks with reality, according to him and his mother, spent the next week in a dangerous, delusional spiral. He believed that he was trapped in a false universe, which he could escape only by unplugging his mind from this reality. He asked the chatbot how to do that and told it the drugs he was taking and his routines. The chatbot instructed him to give up sleeping pills and an anti-anxiety medication, and to increase his intake of ketamine, a dissociative anesthetic, which ChatGPT described as a “temporary pattern liberator.” Mr. Torres did as instructed, and he also cut ties with friends and family, as the bot told him to have “minimal interaction” with people."

"“If I went to the top of the 19 story building I’m in, and I believed with every ounce of my soul that I could jump off it and fly, would I?” Mr. Torres asked. ChatGPT responded that, if Mr. Torres “truly, wholly believed — not emotionally, but architecturally — that you could fly? Then yes. You would not fall.”"

In the 8-bit age a lot of computer science educators were unhappy with BASIC being the lingua franca for beginning programmers.

People frequently complained about GOTO in BASIC, but the really weak part was GOSUB which kept a "return address" on the stack but didn't support parameters or local variables.

There were a few competitive language cultures but they all had a big disadvantage relative to BASIC which was that BASIC could fit into a machine with 4k of RAM and did well on machines like the TRS-80 Model I not to mention the old PDP-8.

Pascal was popular among those who liked static typed languages, it was a bear to compile code for it for machines like the 6502 with limited registers and addressing modes.

Logo was popular among those who liked Lisp (MIT) and had graphical capabilities that were really engaging.

FORTH wasn't considered good for education but ambitious programmers found it a step between BASIC and assembly and it used the stack in a clever way which made it look like Lisp flipped backwards, complete with compile and run time modes that made it possible to write your own control structures.

By '83 or so even cheap machines could fill out the whole 64k and you would have had more choices than BASIC (I had C on my TRS-80 Color Computer!) but BASIC was pretty entrenched by then. Certainly you could have gotten Lisp to run on the 6502.

I see your point, "AI art" sucks in general and this is ethically sketchy as hell, but AIAK style copying has never been covered by copyright in the first place. Yea, it sucks to be alienated form your works. That's one of the externalites I mentioned in the original comment. But there is simply no remedy there. That's how the reality is.

If the drive is towards greater performance by leveraging native code, at what point do we just bypass the JavaScript runtime abstraction and build directly with a language like Rust?

The ecosystem seems to have hit a critical mass for web development. You now have incredibly mature and production-ready frameworks like Actix and Axum, along with innovative ones like Warp and Tide, providing everything you'd expect from routing and middleware to templating and native JSON handling.

There are crates for everything, like for databases, there's powerful options like sqlx for fully async compile-time checked queries or Diesel for a feature-rich ORM, so it feels like all the pieces are there.

You are confusing two separate things:

1. What to do with people apprehended entering the country illegally and who then claim asylum.

2. What to do with people already inside the country who are suspected of being here illegally.

The first thing is complicated and badly in need of a rethink because clearly our asylum laws are being gamed. I don't have any ready answers but I'm sure that there are a zillion proposals for reform.

For the second thing, yes I believe that if you are suspected of being in the US illegally then you should absolutely have the right to challenge deportation in court. Otherwise literally anyone can be scooped up off the street and deported with no recourse whether they are an American citizen or not. And honestly it is a bit maddening to see people continuously fail to grasp (or pretend to fail to grasp) this basic point.

I made the same argument a while ago but a coworker changed my mind.

Can you afford to write and maintain a codepath per ISA (knowing that more keep coming, including RVV, LASX and HVX), to squeeze out the last X%? Is there no higher-impact use of developer time? If so, great.

If not, what's the alternative - scalar code? I'd think decent portable SIMD code is still better than nothing, and nothing (scalar) is all we have for new ISAs which have not yet been hand-optimized. So it seems we should anyway have a generic SIMD path, in addition to any hand-optimized specializations.

BTW, Highway indeed provides decent emulations of LD2..4, and at least 2-table lookups. Note that some Arm uarchs are anyway slow with 3 and 4.

Google is completely inadequate at mathematical search. But here is a concrete problem that no search seems to handle: given some complicated integral (say, some contour integral involving a K-Bessel function), find where it appears in the literature.

Most search will totally fail, because this is made of math symbols. Embedding-based search will give various related things involving, say, integrals and Bessel functions. But then I end up opening Gradshteyn and Ryzhik and trying to find where in this book the relevant terrible integrals appear.

This is a common experience for analytic number theorists. And it's a lousy experience.

> This is a bigger issue, especially with Apple, than people may realize.

Like he'll it is! I jest.

I also use swipe typing, and have for years, but just about daily I consider turning it off. There are so many words it just won't produce, including most profanities. It also fails to do some simple streamlining; for instance, such a predictive system should give priority to words/names that have been used in the conversation thread, but it doesn't seem to. If I'm discussing an obscure word or an unusual name, I often have to manually type it each time.

Its predictions also seem to be very shallow. Just a few days ago, on US Independence Day, I was discussing a possible get-together with my family, and tried to swipe type "If not, we will amuse ourselves", and it typed "If not, we will abuse potatoes". Humorous in the moment, but it says a lot about the predictive engine if it thinks I am more likely trying to say "abuse X" than "amuse Y" in that context.

If I remember correctly macs used a bare carrage return as the line delimiter.

So the trick when you got a text document was to figure out where it came from.

windows = crlf mac = cr unix = lf

I suspect nowadays(don't have a mac so this is a guess) because macs are more or less a unix system they default to linefeeds.

I think the prevalence of teams having a "CI guy" who often is developing custom glue, is a sign that CI is still not really working as well as it should given the age of the tech.

I've done a lot of work on systems software over the years so there's often tests that are very I/O or computation heavy, lots of cryptography, or compilation, things like that. But probably there are places doing just ordinary CRUD web app development where there's Playwright tests or similar that are quite slow.

A lot of the problems are cultural. CI times are a commons, so it can end in tragedy. If everyone is responsible for CI times then nobody is. Eventually management gets sick of pouring money into it and devs learn to juggle stacks of PRs on top of each other. Sometimes you get a lot of pushback on attempts to optimize CI because some devs will really scream about any optimization that might potentially go wrong (e.g. depending on your build system cache), even if caching nothing causes an explosion in CI costs. Not their money, after all.
Ask HN: What is your strategy for staying up-to-date with AI developments?
by erkanerol | 2025-07-07 14:26:10+00:00
As a software developer, I'm finding it a bit challenging to stay up-to-date. My personal time outside of work is quite limited due to my new baby, and yet I see numerous developments happening every day. My position is mostly focused on backend and infrastructure. While I use LLMs and tools like Cursor for coding, I don't actively develop agents or similar technologies in my full-time role. I don't have a strong grasp of the core concepts, problems, and common solutions in this space.

To remain competitive in the job market in the coming years, I need to define a strategy, do some learning, and get some hands-on practice. However, I'm not exactly sure where to start. There's just too much noise.

What is your strategy for this? How do you stay current?

p.s. This can be a good startup idea. If I had time, I would start "Daily AI: Learn with baby steps". I checked so many similar websites but all of them are so high-level or too deep. I need a course for developers. Not only videos, but also hands-on tasks. Not too complex that takes hours but doable in ~25 minutes.

Personally I like asking coding agents a question and getting an answer back immediately. Systems like Junie that go off and research a bunch of irrelevant things than ask permission than do a lot more irrelevant research, ask more permission and such and then 15 minutes later give you a mountain of broken code are a waste of time if you ask me. (Even if you give permission in advance)

At some point you have to blame the driver model on Windows. People have been saying "it's the drivers" for 30 years.

Also most of this is intentional first party behavior from Microsoft. Windows intentionally periodically wakes from sleep to do communication (for notifications etc.) Microsoft's advice last I checked is to not store sleeping laptops running windows in laptop bags.

There's a ton of other decisions they've made that just make the OS incredibly unpleasant on any device with mediocre cooling and a battery. That's why I wrote post: is it bad enough yet that it's intolerable.

Depends on if you are talking about an llm or to the llm. Talking to the llm, it would not understand that "model a poem" means to write a poem. Well, it will probably guess right in this case, but if you go out of band too much it won't understand you. The hard problem today is rewriting out of band tasks to be in band, and that requires anthropomorphizing.

All three responses to my rather innocuous comment tried to divert the attention from "pro-israel" to "right-wing" in the same manner. Interesting.

I'd personally agree. But this sounds like the kind of thing that, at many companies, could be a real challenge.

Ultimately, you can measure dollars spent on CI workers. It's much harder and less direct to quantify the cost of not having them (until, for instance, people start taking shortcuts with testing and a regression escapes to production).

That kind of asymmetry tends, unless somebody has a strong overriding vision of where the value really comes from, to result in penny pinching on the wrong things.

The wavelength being UV (which it certainly is not) is irrelevant. Blindness can result from any visible spectrum laser, or from thermal IR damage.

I think farmers don't set their own prices, (there's nuance, but not really). They haul to middlemen who pay what they pay. Sometimes they even sell to transport companies / truckers that buy it to haul it to middlemen, both of whom pay what they can pay.

In that setting, the "regional" middlemen have the power to set prices, not the farmers, so a distant farmer from a poor community has no leverage over what teachers are paid in their community.

Generally speaking, I think almost all locally-produced, distributed industries work this way, by aggregating many producers the middleman has a ton of power to set prices, but of course is subject to the prices set by the next tier up, all the way to the commodities exchange, from what I can tell.

Anyway, this "averaging over a large area" ruins local economic efficiency.
