Just a small data point/anecdote: I think the calls to install native apps are actually decreasing now. I don't get spammed for that nearly as much as 2014-2018 or so. Even banks seem to be getting comfortable with making mobile optimized websites now.

But like I said, just my perspective, I don't have any hard data points.

I remain perpetually perplexed why people who invoke Mansfield's name almost universally shrink from describing why they feel it is relevant to invoke Mansfield's name.

Yes, there was a Mansfield amendment and a would-be 'nother Mansfield amendment. It had some (waves hands) ever-unarticulated effect on defense funding of research. Motivations of Mansfield are never articulated. Seems so self-defeating to not describe.

No one uses scipy for anything serious anymore in AI research or on any type of modern models.

You're setting your students up for failure if this is how you are teaching neural networks to them. You should switch to pytorch or at least something like tensorflow or jax or you are actively doing intellectual disservice to them and leading them to be actively noncompetitive both in AI academic paper writing/grad school and in the job market.

Similarly, use of sklearn considered harmful in a world where CuML/CuPY/Nvidia RAPIDS exists.

And also, knowledge of conda/pip/poetry considered harmful in a world where UV exists.

Teach MODERN tools please.

Many times traffic lights are poorly designed, or have lost timing over the years and never been tuned back to correct, so you might be fully correct in your frustration.

Sometimes, however, the purpose of traffic lights is to keep the flow of traffic slower to improve safety for pedestrians, bicycles, and other drivers. Especially in down towns when it seems like the light cycles are specifically designed to thwart your desire to simply cruise through at the speed limit, that might literally be happening.

Actual paper: https://www.nature.com/articles/s41550-025-02651-2

From the abstract: “This is the lowest-mass object known to us, by two orders of magnitude, to be detected at a cosmological distance by its gravitational effect. This work demonstrates the observational feasibility of using gravitational imaging to probe the million-solar-mass regime far beyond our local Universe.”

Lol. SpaceX wasn't the first private company to develop a reusable rocket. It was just the first one owned by a billionaire that convince other people to fund it.

SpaceX is notorious in the aeronautical industry for attempting to interfere in the research and funding of other companies. Over a decade ago a competitor had viable plans for a 2 stage rocket... until Musk sued to block the funding.

An optimisation I've always wondered about for transforming/translating/animating elements: is it faster to use JS translations or animation API directly on the element (e.g. style.transform / element.animate), or updating CSS variables with JS to let the CSS engine reposition inheriting elements?

In the context of animations, I'd intuit the latter but would be open to hearing why.

Cryonics doesn't work currently on the scale of human brains. It works at much smaller scales, though. There was a natural experiment where roundworms were revived after 46,000 years [1] [2].

Assessing how well cryonics might in the future at different scales is a prediction. So, yes, cryonics is speculative; it is making a bet that future technologies will somehow bring a brain back to life, in some form. Digital: a brain scan followed by whole-brain emulation. Biological: physical repair at the molecular level. If/when some kind of revival works, the question of consciousness remains.

The current edition of Wikipedia's entry on cryonics writes: "It is generally viewed as a pseudoscience" which is attributed to Jens Karlsson saying "Cryonics ... is generally viewed as a fringe pseudoscience." [3]

I don't care for this characterization. When I think of pseudoscience (such as a homeopathy and astrology) makes claims that are unfalsifiable, often by design. On the other hand, cryonics is falsifiable. Scientists are trying to figure out scales where it can work: it has far to go, and it may not get there.

I personally can't speak to the degree of lies, hucksterism, or fraud swirling around cryonics. I won't defend any such practices.

Will future history show cryonics to be impossible, not dependent on the currently-available technology, but as a provable claim based on the laws of the universe? Maybe. Maybe cryonics is a long-shot worth trying. I'm not an expert, but I lean towards the latter: allocating a small fraction of resources towards exploring it seems wise.

I don't I feel like the people who have benefitted from those treatments find it low quality.

My mother was also bullshitted by a doctor until she got angry and told him what specific test to do and a week later when the test came back surprise surprise, she was right.

My best friend had an intense pain on her side, she went to a doctor and he said it was in her head, she went to another doctor and surprise surprise she had a hernia.

Another friend had constant intestinal pain and digestive issues, the doctor refused to do a colonoscopy and just gave her medication for IBS, she went to another doctor and finally got a colonoscopy and surprise surprise she had a tumor, thankfully they were able to cut it out but it would have been better if they had found it sooner.

Also when I was young I broke my arm and the doctor set it wrong and now my angle of mobility in it is offset.

I have way more stories like this and barely any positive medical stories. If I could go back in time I would have never gone to the doctor and let my body deal with the issue itself. I would be in a lot less pain right now. I hate how righteously arrogant and head up the ass most of the medical industry seems to be.

The entire medical industry has problems, needs to be revamped and the incentives have to be changed.

I watched a company you've probably heard of burn stupid amounts of money because one guy there was trying to build a personal brand as a Graph Database Expert, and another had fallen hard for Neo4j's marketing. Stability issues, stupid bugs, weak featureset, mediocre performance for most of the stuff they wanted to do (Neo4j, at least at this time, was tuned to perform some graph-related operations very fast, but it was extremely easy to find other graph-related operations that it's terrible at, and they're weren't exactly obscure things) all stretching out project development times to like 2x what they needed to be, with absolutely zero benefits for it. So fucking dumb.

Meanwhile all they needed was... frankly, probably SQLite, for their particular use case, having each client of theirs based around a single portable file actually would have been a big win for them. Their data for each client were tiny, like put-it-all-in-memory-on-an-RPi2 tiny. But no, "it's graphs so we need a graph database! Everything's graphs when you think about it, really! (So says Neo4j's marketing material, anyway)"
Show HN: Interest Rate Swaps on DeFi
by vinniejames | 2025-10-14 16:44:21+00:00
Newly launched interest rate swap protocol, just went live on Base today. This opens up the potential for long term, fixed rate loans in DeFi, by providing rate swaps to lenders and speculators. The TradFi market for this is huge, +$400 TRILLION, could be the next big thing in DeFi if this catches on. They're running a points program for early adopters Initial support for rates on Aave, Morpho, Compound, as well as TradFi rates for SOFR, US Treasuries, and US 30yr Mortgages What is everyones thoughts on this?

Gnome isn't dead - it looks more consistent, and in my experience, is running smoothet and cleaner than it ever has (including gnome2 days). It's fine that it's not for you, but comments like this are insane, and not healthy. It's 2025, we don't need to I sult software we don't want to use - just don't use it.

(And, threatening to move back to something like openbox, because gnome is too simple and degraded, is extra hilarious)
Show HN: Problem Board – Where people share frustrations, makers find ideas
by mergehope | 2025-10-14 16:44:53+00:00
Hi HN,

I built Problem Board because I kept hitting the same wall: "solve a real problem" is great advice, but finding genuine problems people actually care about is harder than building the solution.

Problem Board connects two groups:

1. People with daily frustrations (no matter how small) 2. Makers looking for their next project

How it works:

- Someone posts a problem they face - Others can "Watch" it (shows interest/validation) - When 3+ people watch → status becomes "Trending" - Makers can build solutions and share links - Original poster can mark it "Resolved"

Real examples currently on the board: - "I spend 15 minutes every morning deciding what to wear" - "My apartment is cold but I don't know why"

The goal isn't to monetize problems or create a freelance marketplace. It's simply a place where raw frustrations become inspiration—and where makers can validate ideas before investing weeks of work.

Tech: React + Firebase, hosted on Vercel.

Just launched today. Would love your feedback on the concept and execution.

A brief search in Chinese social media turns out:

- the cases are rare, once every several months

- the affected battery pack is usually replaced free of charge

- many of the cases are from Chinese in North America, and even one case is about imported Model 3

Considering Chinese media prefer reporting Tesla defects to gain more clicks, I would assume this is not a Shanghai-specific, broadly affecting problem.

>Is this duct tape over historical architectural decisions that assumed trust?

Yes, it's all making up for flaws in the original Unix security model and the hardware design that C-based system programming encourages.

> Could we design something with less complexity if we designed it from scratch? Are there any operating systems that are designed this way?

Yes, capability architecture, and yes, they exist, but only as academic/hobby exercises so far as I've seen. The big problem is that POSIX requires the Unix model, so if you want to have a fundamentally different model, you lose a lot of software immediately without a POSIX compatibility shim layer -- within which you would still have said problems. It's not that it can't be done, it's just really hard for everyone to walk away from pretty much every existing Unix program.

Investing in AI infrastructure seems very risky to me. With how short of a lifecycle computing hardware generally has, does it make sense to blow billions on hardware that will need to be replaced in a few years? AI companies have been burning billions on hardware. Will the costs of that hardware be covered by profits before the hardware lifecycle is up? That's a big gamble.

We used to talk about AI as having no moat (easy for other players to accomplish similar AI achievements). China has made that clear. Some open weight LLMs are fine and can run on laptops. It seems the new moat is model parameter size and VRAM requirements. I would bet on innovation in hardware or disruptive algorithms changing that game so better LLMs can run on more personal computers. Remember how bitcoin miners all used GPUs then ASICs came along and made that no longer profitable?

There are many ways the AI industry can be disrupted which makes it that much more volatile.

> Plenty of big services will just give cops info if they ask for it. It's legal. Any company or individual can just offer up evidence against you and that's fine, but big companies will have policies that do not require warrants.

I think this is where policy is failing. No clear protections on privacy and collusion between corporations and the state is allowed. It’s outdated and impractical to have the limits on search and seizure at physical boundaries but not electronic ones.

For the first time ever I ran into a web app blocking Desktop Mode on Chrome for Android somehow. (ChowNow) I've seen sites detect it but issue a warning, but this was a full functionality-block.

I was literally using it fine one day, then the next they started saying I need to use the desktop website for menu editing as it's "more optimized."

Dinguses, if I'm manually turning on Desktop Mode I know it's not gonna be "optimized." Just let me get my menu edits pushed goddamnit!

How is that a nitpick? Seems like Graphene is for those who want to have finer-grained control of what Google tracks. You are still funding Google through a hardware purchase (Pixel phone). You are still using Android. And it seems to be a big selling point that you still have access to the (sandboxed) Play Store Apps and services.

I'm pretty NASA signed the deal knowing full well that they were taking a big risk. The chances of Starship HLS being a Long Poll item for Artemis III were high. They chose Starship HLS knowing that it had a long and risky critical path.

And In fairness to NASA....and I may not have all of these details correct, but they didnt have many choices. the NASA Reauthorization Act required them to select two different landers for HLS, but the budget only funded one and under funded them at that. Starship was all that they could afford. Congress has since gone back and funded a second one.

Congrats. You are doing exactly what I said above. I provided a link to a news story from a local PBS affiliate, pulled a direct quote from that very story which it attributed to the mayor and you either didn’t read the source story I posted, or want to claim it is inaccurate because of some special proximity knowledge you have. So be it. However, since you want to call the source into question, here is the exact statement from the Broadview mayor on the Broadview government site. That is the full statement that the story quoted—The quote I posted that you claimed was never said because it was never mentioned in Facebook posts (Wow). The PBS affiliate story was accurate, the quote was accurate to the Mayor’s statement, and frankly, you were wrong. Perhaps you should “Please be more careful”, right?

From the Broadview Statement:

“There are too many protesters abusing their right to protest. Too many are raising their fists rather than their voices, creating chaos at the expense of the people who call Broadview home.”

https://broadview-il.gov/reference/press-releases/press-rele...

Feel free to dispute this all you want, feel free to diminish what it says, but know that you are doing exactly what I said…propagandizing from the other side of the coin.

Boeing vs Airbus:

The redder the pixel, the more Boeing planes there.

The greener the pixel, the more Airbus planes there.

The bluer the pixel, the more non-Boeing/Airbus planes there.

The less transparent the pixel, the more planes in total.

White means all planes fly there, yellow means Boeing and Airbus dominate, red means Boeing dominates, green means Airbus dominates, cyan means Airbus+others, magenta means Boeing+others, etc.

I've seen an application, a 95% CRUD application, which had about 100-1000 users across the UK, users who would only be using it from 9am-5:30pm, and at that - barely interacting with it. This was backed by literally the most sophisticated and complex architecture I have ever seen in my entire life.

There were 3 instances of cognito. RDS, DynamoDB and S3. The entire architecture diagram would only be legible on an A2 (heck, maybe even A1) page. And that was the high level diagram. The central A4 part of that diagram was a bunch of micro-services for handling different portions of this CRUD application.

This company could afford a system architect as well as a team of developers to work on this full time.

I was genuinely baffled, but this company was in an extremely lucrative industry, so I guess in this case it's fine to just take some of your profits and burn them.

The loudness means that when people yell "The government are doing X" you can go see for yourself, are they doing X? No? So what was the yelling about?

Going to Portland to check whether it's on fire would be a lot of effort - so to some extent I must take it on trust that it's not actually on fire despite Donald Trump's statement - whereas visiting crt.sh to check for the extra certificates somebody claims the US government issued is trivial.

A smartphone is essential to operate in the modern world. Facebook is not necessary at all.

Google and Apple are holding the entire world hostage.

I can't even order food at half the restaurants I visit any more without a Google or Apple device. They're all using smart phone QR code menus. It's absurd.

Imagine what happens when they're the only way to pay. When they're the only form of government ID.

Do we really want these devices to be locked down and not owned by us? This much responsibility should be a business liability imposed by the governments of the world, not unlimited permission to tax and coerce without impunity.

Imagine if your government was as free as your smartphone. We wouldn't have elections. We'd have no freedom, no peace of mind, forever renters. Bad choices would be imposed upon us as defaults. The government would make us more dependent upon them. If we had a business, we'd be taxed 30%, told we couldn't have a relationship with the customer, made to jump through frequent hoops, deal with constant friction, have to pay protection racket money to avoid ads, have everything we do monitored and controlled, be subject to takedown whenever and for whatever reason, not be allowed to issue updates or use our own technology, have the government themselves compete with us and look at our data...

The governments of the world need to end this.

"Fully specified" is the important part here, and the work that went into making the idea fully specified is where the value lies.

For this, we could look at intellectual property laws. Ideas are not protected. Neither by patents, nor copyright, nor trademark. If you want to make your idea worthy with regard to the law, you have to "fully specify" it, turning it into an invention (patent), or code (copyright).

Maybe because a single app on a single server rarely stays a single app. And while the landscape has generally improved, and imo is better under Linux than windows... there's nothing worse than trying to get a handful of .Net and Java applications installed and working in concert on a Windowss server with multiple framework versions for the differing apps. Let alone harder dependencies.

Docker for Windows Containers itself was a horrible exercise in frustration just because of it's own dependency issues, and I thought it was a bad idea from the start because of it, and it dilluted Docker for Linux IMO.

Docker/Containers and Compose are pretty great to work with, assuming your application has dependencies like Databases, Cache, etc. Not to mention options such as separating TLS certificate setup and termination from the application server(s) or scaling to larger orchestration options... though I haven't gone past compose for home-lab or on my own server(s).

I can also better position data storage and application configurations for backup/restore by using containers and volumes next to the compose/config. I've literally been able to migrate apps between servers with compose-down, rsync, dns change, compose up -d on the new server. In general, it's been pretty great all around.

In this context, “dark object” really does mean a localized blob of dark matter, not a black hole or a dim, normal-matter object.

The research team detected it only through its gravitational lensing effect — the way it slightly distorted the light from a more distant galaxy. There’s no emission at any wavelength (optical, infrared, or radio), and its gravitational signature matches a million-solar-mass clump of invisible mass rather than a compact point source like a black hole.

They specifically interpret it as a dark matter subhalo — one of the small, dense lumps that simulations of “cold dark matter” predict should pepper the universe’s larger halos. It’s too massive to be a single star, far too diffuse to be a stellar remnant, and not luminous enough to be a faint galaxy.

So “dark” here isn’t just shorthand for “too dim to see at this distance” — it’s used in the literal physical sense: matter that doesn’t emit or absorb light at all, detectable only via gravity.

Eventually, all the dark matter clumps into rings around galaxies, but since this one is so distant, ~10B light years, so we are seeing that clump as it was that long ago before it difused into it's ring shape we can see in the galaxies around us.
