There is a dry pasta I use that, long story short, comes without a listed cooking time, whose correct cooking time I have experimentally determined to be ~18 minutes (though remarkably flexible, good at a much wider range than "normal"). I like it quite a lot (even though it seems to have the teflon-die surface rather than the bronze-die surface).

I think greater pasta thickness is underexplored, and the teflon-vs-bronze die thing as the highest determinant of pasta quality, while not nothing, is slightly-overstated r*dditry.

> Is your complaint that it has errors?

Well, yes? There's a reason why everything that was produced with these tools so far is garbage: because no one actually caring about their art would accept these things. Art is a deliberate thing, it takes effort. These tools are fine for company training videos and TikToks. Of course a few years ago this was science fiction. They are immensely impressive from a technical perspective. Two things can be true.

Consider it holistically, rather than one at a time. Every company has its own footprint of "per customer" resource usage, and every company probably has unusually low aspects one way or another, but when a company comes back as "low" to "very low" for every such metric, it's time to investigate harder. Maybe they're just that genius, or maybe there's something about the company you don't understand yet, or maybe they're cheating you... the whole point of due diligence is to resolve those "maybes" into "certainlies", because they all factor in to your decisions.

Australia Kmart got a good round of applause recently on HN and I think it was because of this reason. MZOO prices but with Kmart brand curation (they use their own brand name Anko alot but under the hood must be different suppliers etc.). Not sure how they do it and pay all that staff and rent, but they do!

Wrong law.

This is GDPR. So long as they conform to the 13 principles then HN will be fine. Its nothing to do with the online safety act.

For the OSA (which I think is very badly drafted, and poorly enforced by OFCOM) so long as there is decent moderation (which there is), a way to report posts (there is) and the site doesn't persistently host actual abuse, then you're mostly fine.

It doesn't help that OFCOM are unwilling to change the scope of guidance to match the size and type of community.

Wow, I did a very similar thing on the first date with my now wife. I explained the halting problem, and Godel's incompleteness theorems. We also talked about her (biomedical) research, so it wasn't a one sided conversation.

I think dominating on a first date is a risk (which I was mindful of) but just being yourself, and talking about something you're truly passionate about is the key.

Related - there's also a 6th Edition Unix port to "big iron" TI990 minicomputers by Dave Pitts, which are based on either the TMS9900 or discrete TTL implementations of it:

https://cozx.com/dpitts/ti990.html

You can find a lot of additional tools there, e.g. an assembler, a GCC port, a TI990 simulator and lots of disk images of and applications for TI's DX10/DNOS OS for the 990 series.
Ask HN: Is there a reliable, unlimited, mobile data hotspot available in the US?
by idontwantthis | 2025-09-30 19:09:42+00:00
If cost is not an issue, how do you get a mobile hotspot plan that 1) Has no limit, 2) Isn't deprioritized or throttled ?

My cell provider offers like 10GB per month, last priority. Internationally, I had no problem because mobile data isn't nearly as expensive in most other countries, and they don't bother to throttle it most of the time.

Sharpe ratio is a metric that measures how much excess return an investment earns per unit of risk. So if someone says “this fund runs at a 4 Sharpe,” they mean the fund’s returns are four times the volatility, net of risk-free rate.

Super super ELI5 is that people don't like volatility in returns, even if the returns are good (i.e. down 40% one year, up 200% the next year is 34% CAGR, but crazy volatility). T-bills for example have extremely low volatility but also very low return. The holy grail is very low volatility with a great return. A 4 sharpe fund is in that quadrant.

Not really data loss per se, but let me add my own story to the pile: just last week, I had a btrfs filesystem error out and go permanently read-only simply due to the disk becoming full. Hours of searching and no solution to be found, had to be reformatted.

I don't understand how btrfs is considered by some people to be stable enough for production use.

I can only speak for a few companies that I know of here, but not really, no. Programmers are really needed. Now, you're going to be working on firmware and with chips (C, BASIC, python, etc), so it's not the stuff that may be in vogue these days at FANGs. Also, yeah, again, the pay is lower.

> This is awful. It's cutting out any money going to the news agencies that go out there and write news. If they didn't exist, Kagi wouldn't work.

Why would Kagi stop working if news didn't exist? Kagi is a search engine first and foremost, Kagi News is not a money making product of theirs. Kagi would still be making money with their search engine.

Also, this should entice news writers to write better news. The main reason people use products such as this is that they are sick and tired of going to news sites only to have to power through filler material to get the 10% that actually matters...
Show HN: IG Email Finder – Find Verified Instagram Emails for Outreach
by joseatanvil | 2025-09-30 19:10:22+00:00
We built IG Email Finder to make it easier to get verified emails from Instagram profiles. You can enter usernames one by one, upload a CSV, or connect a Google Sheet. The system uses deep research and currently returns about 60 to 75 percent verified results depending on the niche.

It started as something for influencer outreach, but people are also using it for sales and lead generation. Happy to share more details and would appreciate feedback.

Location consistency is important. Even something as simple and subtle as breaking the 180-rule [1] feels super uncanny to most audiences. Let alone changing the set the actor occupies, their wardrobe, props, etc.

There are lots of tools being built to address this, but they're still immature.

https://x.com/get_artcraft/status/1972723816087392450 (This is something we built and are open sourcing - still has a ways to go.)

In this situation, humans are more accurate, for now, so it's good information to have.

Same as I would like to know if humans self assessed in a study about how well they drive vs the empirical evidence. Humans just aren't that good at that task so it would be good to know coming in.

Just call it Kagi Vibes instead of Kagi News as news has a higher bar (at least for me)

Even if pg where here to do so, it wouldn't happen the way you think it would. Open source got ate by AWS and closed behind paid for services. We had those discussions in the past, we lost, the market spoke.

Moreso the internet evolved into something we don't like. In the early days it wasn't that hard to have an energetic conversation because you were having conversations with real people at their digression. Yes, there were some number of trolls you had to deal with, but over time they went from being the exception to being the rule. Any and every site you create now, the moment you collect a worthwhile market will be flooded with those attempting to market their wares to the point that actual conversation can no longer exist. The walled-gardens and verified signatures are a side effect of the infection that the internet has become.

The world you lived in aged and died and now a brave new world screams for your attention 24/7 without care for your health or sanity. The days where a large portion of people were into programming because they enjoyed it are long past. People need paychecks to support the ever spiraling costs of basic needs. Consolidation and monopolies aren't just a thing in websites and computer hardware, it's a thing everywhere with everything especially in the US. The power scaling laws of technology have come home to roost. The cyberpunk dystopia we were warned of is already here and the masses invited it with open arms.

The FOSS utopianist need to realize they lost, and it's human laziness and apathy that was the killing blow. If you can come to terms with that, maybe a rebirth of FOSS that targets our base instincts can arise.

“Trash” is too harsh of a word, but I do feel that desktop Linux lacks the fit-and-finish of Windows and macOS. It boils down to development resources. The Mac ecosystem has a much smaller number of hardware configurations that macOS needs to be concerned about. Apple has the resources to test these configurations. Even in the PC ecosystem with its plethora of hardware configurations, Microsoft is also a well-resourced company and is thus capable of testing a wide range of configurations. The Linux ecosystem, on the other hand, is much more loosely coordinated among many different parties that may or may not be acting in accord with each other. There are no Apple- or Microsoft-level entities investing hundreds of millions of dollars into desktop Linux development.

In fact, given the circumstances, it’s quite impressive we have desktop Linux at all. Even with its Sisyphean setbacks, it’s come quite a long way compared to 20 years ago when I first started using Linux.

Agreed! The gulf between pure-C++ CUDA and PTX is getting larger with these optimizations. My understanding is that Deepseek used PTX instructions that either had no corresponding C++ implemented (like `wgmma` mentioned in the article) or uncommon permutations of modifiers (`LD.Global.NC.L1::no_allocate.L2::256b`).

As an undergraduate I worked with some other Physics students to construct an analog circuit using op amps that modeled one of Sprott’s equations and we confirmed experimentally that the system exhibited chaotic behavior. We also used a transconductance amplifier as a control parameter and swept through the different states (chaotic, period windows) of the circuit. We did not go as far as comparing the experimental and predicted period windows while I was there but it was an interesting project for us. At one point I turned up an article in Physica D describing how to calculate the first Lyapunov exponent using small data sets which we used to compute whether we were in a period window or not.

Cerebras hasn’t made any technical breakthroughs, they are just putting everything in SRAM. It’s a brute force approach to get very high inference throughput but comes at extremely high cost per token per second and is not useful for batched inferencing. Groq uses the same approach.

Memory hierarchy management across HBM/DDR/Flash is much more difficult but necessary to achieve practical inference economics.

> Also, passengers are probably going to start waking up to the realities of just how bad the air-travel experience in the US has become compared to so many foreign counterparts. If you want passengers to want your plane, design it without sardines in mind; People don't like being sardines.

I hope this is true. However, my sense is that the value chain is so elongated from aircraft designer/engineer/marketing/sales to the end customer (retail airline passengers) that those important signals are lost. Not to mention the financial incentives on the part of US domestic airlines to keep making the flight experience worse for end customers.

> The mathematicians of 100 years ago also all understood, and the meaning hasn't changed over the 100 years.

Isn't that the subject of the whole argument? That mathematicians have taken the road off in a very specific direction, and everyone disagreeing is ejected from the field, rather like occurred more recently in theoretical physics with string theory.

Prior to that time quite clearly you had formal proofs which do not meet the symbolic abstraction requirements that pure mathematicians apparently believe are axiomatic to their field today, even if they attempt to pretend otherwise, as argued over the case of Euclid elsewhere. If the Pythagoreans were reincarnated, as they probably expected, they would no doubt be dismissed as crackpots by these same people.

> though if Apple suddenly took gaming seriously, like extending Rosetta to act as a translation layer for Windows games a la Proton, I’d gladly throw down for an M5 Ultra when it’s released

No joke, if I could run my Steam library on my phone, I'd probably buy a new phone every year (and might need to, given what the thermals and rapid charge/discharge cycles would do to battery longevity). But Apple's current strategy is to provide a tool, then let developers do the work themselves; compare to Valve's efforts (and occasionally stepping on rakes when games update themselves).

>But all things being equal, investors would like their money allocated into projects with the best returns. Borrowers of course would prefer that they get the money so that doesn't really tell us anything, but society as a whole would rather that worthy projects are funded rather than a linear city in the desert or whatever.

you are describing the process by which competitive "jostling for the best returns / cheapest capital sources" produces market efficiency, which makes it pointless to try to find better returns or cheaper capital. Not having to think about that is a reward itself. The price of oil is established by auctioning off more oil every day; if you buy some at an auction, you're doing the best you can do, there is no better place to invest in oil, you can focus on driving your fleet of delivery trucks.

Yes. It made me realize how much intelligence is in these models that isn't being exploited due to minor details of the harness. I've been doing this as a side project and it took nearly no effort to get something that I felt worked better than every other agent I tried, even if the UI is rougher. We're really in the stone age with this stuff. The models are not the limiting factor.

There’s a beautiful conference (which I’ve lost) saying that science and technology can regress. We always talk about “the progress” but things do regress all the time; Tests I’ve cleared for employment can’t be passed by newcomers, the NASA wouldn’t be able to put a rocket on the moon today, and there is no downloadable Jira competitor anymore.

In fact the speed of innovation is, pretty much, equal to the speed of maintenance. Nothing gets maintained, it’s either new or collapsing, but no-one enjoys the middle part. Which is sad. It’s a form of inflation.

Boeing is perfectly right to design a new plane right now. Engineers who interned on the 787 have bought a house on the countryside a few years ago.

It is, but it isn't quite the same as C, either. That is to say, there is some semi-unknowable stack of stuff happening under the covers.

I will predict the future: you will pull up the JIT assembly output to make the case that they output similarly performant assembly on your preferred platform, and that you just have to do X to make sure that the code behaves that way.

But my problem is that we are invoking the JIT in the conversation at all. The mental model for any code like this inevitably involves a big complex set of interacting systems and assumptions. Failure to respect them results in crashes or unexpected performance roadblocks.

Imgur isn't a person, and the UK gov isn't ICE.

The whole point of corporations is that the company is liable, not its employees. also the shareholders are only liable for the money they put in, and not anything else.

Convictions in the UK are non-transferable. you can't convict a company, then transfer guilt onto its employees, they need to be tried at the same time.

Please note that the post didn't mention the word benchmark a single time ;) It does a "basic performance measurement" of "our csmith example". Anyway, thanks for your notes, they are very welcome and valid.

Comparing TPDE against the default optimization level in ORC is not fair (because that is -O2 indeed), but that's what we get off-the-shelf. I tested the explicit FastISel setting and it didn't help on the LLVM side, as you said. I didn't try the command-line option though, thanks for the tip! (Especially the -pass-remarks-missed will be useful.)

And yeah, csmith doesn't really generate representative code, but again that was not stated either. I didn't dive into JITLink as it would be a whole post on its own, but yes feature-completeness prevailed over performance here as well -- seems characteristic for LLVM and isn't soo surprising :)

Last but not least, yes multi-threading isn't working as good as the post indicates. This seems related to the fix that JuliaLang did for the TaskDispatcher [1]. I will correct this in the post and see which other points can be addressed in the repo.

Looking forward for your OrcCompileLayer in TPDE!

You can absolutely take that stance and be fine as long as you never get into the sphere of influence of UK law enforcement for potentially a very long time.

If they get hold of you your interpretation of who sent what doesn't matter but theirs does. They can absolutely hold you until your fine is paid or you spend and equivalent amount of time in prison.

Many people like to vacation in the UK or Europe (one diverted flight away) and they might decide that it's better to just block users and be done with it. Some people may even happily pay a small fine incurred before the block.

Very interesting tech. Ephemeral, high-fidelity preview environments that require zero setup are a key enabler. They let you rapidly validate changes within the complete context of a web or mobile app, accelerating feedback loops and cutting friction for minor updates. This also empowers business users to safely implement small, self-contained UI adjustments which is particularly powerful when combined with LLM-driven suggestions.

Whatsapp elaborately explained how it was doing this to the public, it was with a technology (Erlang/OTP) that had rarely been used before, and that technology had been designed for and very successful in an almost identically shaped context (telecom switches.)

Also, more obviously, people you knew were using it every day. 450M is different than 4M, and way different than 300K. If Whatsapp were lying and saying they had 4.5B users, I'd expect JP Morgan to catch that within a few hours, too.

I wonder if they're going to license this to brands for heavily personalized advertisement. Imagine being able to see videos of yourself wearing clothes you're buying online before you actually place the order, instead of viewing them on a model.

If they got the generation "live" enough, imagine walking past a mirror in a department store and seeing yourself in different clothes.

I'm optimistic here.

Look at 1900s tech like social security number/card, and paper birth certificates. Our world is changing and new systems of verification will be needed.

I see this as either terribly dystopian - or - a possibility for the mass expansion of cryptography and encrypted/signed communication. Ideally in privacy preserving ways because nothing else will make as much sense when it comes to the verification that countries will need to give each other even if they want backdoor registry BS for the common man.

Breaking changes get fixes.

To take a moment to be a hopeless Stan for one of my all-time favorite companies: I don't think the summary above yours is fair, and I see why they don't center the summary part of it.

Unlike the disastrous Apple feature from earlier this year (which is still available, somehow!), this isn't trying to transform individual articles. Rather, it's focused on capturing broader trends and giving just enough info to decide whether to click into any of the source articles. That seems like a much smaller, more achievable scope than Apple's feature, and as always, open-source helps work like this a ton.

I, for one, like it! I'll try it out. Seems better than my current sources for a quick list of daily links, that's for sure (namely Reddit News, Apple News, Bluesky in general, and a few industry newsletters).
