That would be great in a idealistic world where the establishment is not building a control grid using surveillance capitalism rather use the technology to benefit the anology world. In the current geo-political climate the question is do one want to get paid to build one's own digital prison?

Only training the experts should be doing is the ones that is self-hosted or through community of people one trust! Currently none of the big corp qualifies, not sure if the structure of big corp (that it is a person-hood) is capable of creating anything beneficial in the long run.

Why should the big companies benefit from your expertise to build centralize their control?

I think the main benefit of a neuromorphic design would be to make it dataflow driven (asynchronous event driven - don't update neuron outputs unless their inputs change) rather than synchronous, which is the big power efficiency unlock. This doesn't need to imply a spiking design though - that seems more of an implementation detail, at least as far as dataflow goes. Nature seems to use spike firing rates to encode activation strength.

In the brain the relative timing/ordering of different neurons asynchronously activating (A before B, or B before A) is also used (spike-timing-dependent plasticity - STDP) as a learning signal to strengthen or weaken connection strengths, presumably to learn sequence prediction in this asynchronous environment.

STDP also doesn't imply that spikes or single neuron spike train inter-spike timings are necessary - an activation event with a strength and timestamp would seem to be enough to implement a digital dataflow design, although ultimately a custom analog design may be more efficient.

> I would pass my SSH connecting used for socks5 through ROT13 or any ROTn, then the firewall won't gradually slow it down towards total stall after a few kilobytes. OpenSSH yells its name and version in plain text upon connection.

Could you elaborate on that more? I'd love to dig into an implementation that does this, in case you still have the tools/scripts/programs available.

I'm asking because for the last couple years I've been on and off working on my warps [1] soft router prototype which aims to hide in plain sight using exfil network protocols.

(Think of it like DNS/HTTP smuggling but with the idea to use similar techniques in other network protocols, too)

I'm not seeing where they are coming up with RNT as a cause, other than a lot of theory. Wouldn't it be a symptom of cognitive decline instead? Dementia patients, particularly those with Alzheimers, tend to become depressed because of confusion and memory loss. Wouldn't it be more likely that these depression symptoms are being caused by deteriotating brain function rather than the other way around?

> RNT was assessed using the perseverative thinking questionnaire (PTQ). The scale consists of 15 items covering three domains: core characteristics of RNT, unproductiveness, and psychological capacity captured. Each item is rated on a 5-point Likert scale from 0 “never” to 4 “almost always”, with a total score ranging from 0 to 60.

Can someone who works in this field explain to me how this study is anything other than evidence of one exam being a proxy for another?

The "Repetitive Negative Thinking" is then just, like, a marketing term for their questionnaire?

I don't see the questionnaire itself in the study (maybe I'm missing it?). Without understanding what questions were answered in a questionnaire, how am I supposed to take anything away from this study?

Hey HN,

I’m building Cloud fox, a platform for developers and freelancers that combines IP tracking, AI-powered collaboration, multilingual meetings, and blockchain infrastructure. The goal is to help remote teams work globally without trust issues or project disputes.

We’ve already got 10k early adopters signed up for free early access, and our beta testers report smoother collaboration and better IP security.

Curious to hear feedback from developers, freelancers, and anyone interested in cross-border collaboration tools.

Ah, I completely support your righteous anger against the tragicomedy of US "IP colonisation", though note that it has not much to do with my comment about the possibility of an open source patent.

The fact that most of the world was just laying down belly up to accept the negative consequences of the ridiculous cottage industry of churning out patents "for later" is truly enraging if someone gets to see how little value it produces. (It's very convenient for large conglomerates, VC fueled startups, and ... that's it.)

When it comes to specifics, ie. with pharma, it's hard to really disentangle the mess from other ugly facts, like the post-WWII global economy which and the very misregulated US healthcare industry (R&D including).

The US is subsidizing R&D for the world, because the other rich countries have sane "collective bargaining", but this leaves the small not so rich markets out in the fucking cold, because they have a weak bargaining position (market access doesn't worth that much to pharma companies) and also usually no internal R&D (so no local companies filing for these trivial parents). But because of all this in effect the world is buying R&D at the worst price!

(Though of course the picture is more complicated than this, but R&D is definitely waaay too inefficient in the US, but also all over the world too.)

“The prevalence of cognitive disorders is increasing year by year, placing a heavy burden on patients, families, and society. It is estimated that the total annual cost of dementia disease in China will reach $1.89 trillion in 2050 [4]. However, there is no drug that can stop or reverse the progression of dementia.”

That is my own RNT. If only there were a way to escape from this reality. Death, taxes and global population collapse while a huge proportion of the voting population loses their ability to do basic tasks while still clinging to political hegemony in the nations they destroy. What a great time to be alive.

I'd take tests over docs but that's a false dilemma.

What does the (Copilot) /tests command do, compared to a prompt like "Generate tests for #symbolname, run them, and modify the FUT function under test and run the tests in a loop until the tests pass"?

Documentation is probably key to the Django web framework's success, for example.

To be clear, I'm saying that Biden fought for Griner because she was famous, not because she enjoyed cannabis and liked the ladies or whatever it is Kirk seems to think. Spies aren't famous by definition.

It's reasonable to disagree with Bidens choice, but it's rage bait to make it about her skin color and toilet-part preferences.

That's what Kirk did for a living though.

>One day, after "seeing" some good shots in my head and totally missing them due to phone camera limitations, I decided I had to fix it.

That was my problem. Went to an air show and used my iPhone 13 and got some good pictures. iPhone 16 comes out and it’s got a 5x zoom and the best camera ever. You’re gonna love it. And the pictures were better but still ok.

So I’ve gone all in and bought a proper Canon mirrorless and a selection of lenses including a 100mm to 400mm and it’s miles better.

I tell the camera what to focus on , I set everything and I control what it does no software second guessing me and taking a lovely picture of a tree and not the eurofighrer in the background.

I love that it’s got one job and it does it brilliantly.

Governments aren’t banning or restricting it because “god said it was bad”. Nor is the GGGP arguing that we should take it seriously because governments do so. Those would be specific appeals to authority. The GGGP argument uses examples of cases where social media has been taken seriously enough to result in government regulation to directly rebut the GGGGP’s claim that social media is only being discussed on substack and not more broadly.

Irrational, perhaps, but also totally understandable and unlikely to change.

People fly but it requires a huge amount of trust to put yourself in someone’s hands like that, where if something goes wrong the results are catastrophic. People have faith in the regulations, they trust that the pilots are well-trained and the planes well-maintained, to the point where the chances of catastrophe are so small it overcomes their natural fears.

The same is true of the nuclear industry. The only thing making nuclear a remotely popular option is the extensive regulation which makes the risk to the consumer so small it outweighs their fears.

And the trouble is that it is up against solar and wind, where the cost is much smaller, and the absolute risk - if you discount people who choose to working to install them - really is very close to 0.
Show HN: Flappy Lid – Control a Flappy Bird clone with your MacBook's lid sensor
by flappylid | 2025-09-14 13:35:27+00:00
I built a Flappy Bird clone that you control by opening and closing your MacBook lid. It uses the hinge lid angle sensor recently discovered by @samhenrigold!

This has no monetization, no ads, and is all ran locally. This is a throwaway account as I'm not sure I ever want this abomination attached to me professionally.

There are two game modes: "Easy Mode" where the bird follows your lid position directly, and "Flappy Mode" where you flap the lid to jump (with proportional jump heights based on how much you move the hinge).

Are the 10- and 40- series similar? Before the 1650 I had the 1060 in the same PC, and for a while I had an RTX 4060 in it as well (which I bailed on because the model emitted terrible coil noise). Neither really made any mentionable difference in idle power. I'm personally convinced that besides "NUCs" and running on only a 25-35W AMD APU with no discrete graphics card, the days of low-power stationary PCs are long over.

I have a different approach I’ve used for about 10 years that I like a lot. All password metadata is stored in a plain JSON file indexed by name (usually site name). Each entry contains at the minimum a username. Optionally it has a version number and some password rules like the length (20 if absent) and the character classes that are allowed, along with how many of each character class are required. None of this data is sensitive, so if you look at the file you see my list of sites. The actual passwords are not stored, because my tool is actually a deterministic password generator, which prompts me for a passphrase and generates a password from the passphrase and a hash of all the metadata. One nice feature is that if I just change the version number I get a whole new password, and the “history” is still available by changing the version back.

The one major downside to it is that it is absolutely unusable for sharing passwords because obviously that would require sharing my passphrase, and there is no way to “store” a password that someone else set. I’ve thought about writing a mode that would encrypt a string (eg a shared password) with the metadata-generated password and store it in a separate piece of metadata for that purpose, but the number of times I’ve needed that has been extremely small.

All major universities public and private are heavily dependent on federal dollars in numerous ways.

The Fed has tremendous financial and regulatory power over any institution of any size.

Large corporations have been bending the knee for the same reasons. I highly doubt Tim Cook is a huge Trump fan but he was right there to kiss ass on day one. That’s because Trump could, with the stroke of a pen, decimate Apple’s business by destroying its global supply chain.

Actual conservatives and actual libertarians were warning about growing Federal power for decades and decades and they had a point. Nobody listened of course.

This site and the nearby Saddam palace were featured in the recent Michael Palin travelogue on Iraq.

The reconstruction looked very bare and empty in the program. But I guess it is a work in progress.

BTW the Assyrian exhibits in the British museum are amazing and well worth visiting. Yes, I know, colonialism is bad and they probably shouldn't be in London. But I doubt they would be in anything like as good a state if they had been left in their original locations.

It is the traveler's responsibility to know what activities are permissible given their visa, and to only engage in those activities. That's no different from everyone's general responsibility to abide by the law.

A US visa is simply permission to present yourself at a port of entry for admission, at which time you may questioned further by border control, and in rare cases denied entry.

Most B visas are valid for multiple entries over 10 years. The fact that you wrote a letter and brought it to your original visa interview (which may have been years ago, and likely wasn't even looked at by the officer, who in a busy consulate has less than 2 minutes to complete your interview) does not mean the US government has affirmatively granted you permisison to do everything on that letter.

Huh, I actually thought this particular piece of woo had mostly died out at this point; haven't heard much about it for a few years.

I'd vaguely assumed that it was bored anti vaxers looking for a new Big Bad, but apparently it was Joe Rogan in 2020. Per Google Trends, it seems to have peaked early 2025, which is _much_ later than I thought. Maybe this is a consequence of dumping twitter; I'm missing out on important Oil Discourse.

I was exaggerating a bit for comedic effect. I can completely sympathise with the sentiment.

If there was a way to prove one's identity/age online, double anonymously (so both the website doesn't know who you are, and the identity service doesn't know what website is asking) I'd be a 100% for it. It would prevent minors from accessing stuff they're not ready for (on average), and it would limit the amount of bots and foreign interference.

I'd say that you care about it being UNIX-like, not UNIX®. You don't care that Linux isn't UNIX. You don't care that GNU versions of things like ed and awk are slightly off-spec.

In some ways, Apple's adherence to UNIX specifications probably makes macOS less useful for you. For example, I wish that grep on macOS was closer to GNU grep. When I look up commands online, I often find answers based on the GNU implementations. Those often work on macOS, but sometimes don't (or have subtly different behavior) because macOS is adhering to the UNIX specification rather than to what those utilities do on the vast majority of systems out there.

I don't think Apple would be removing UNIX-like tools from macOS even without certification. They know how valuable it is that most developers use their systems. Even Microsoft went so far as to implement the Windows Subsystem for Linux for developers. At this point, I think that UNIX certification makes macOS less compatible with the tools and help out there which generally targets Linux. Usually the differences are small, but they certainly can be meaningful.

There are a few methods to make rhombohedral graphene (which demonstrates superconductivity at room temperature).

Normal carbon stacks into a hexagonal ABAB pattern.

For superconductivity, the layers need to be at least ABC (because twisted bilayer graphene does not demonstrate the effects (superconductivity, quantum hall effect) at room temperature FWIU).

Current process: CVD chemical vapor decomposition and then sort and stack graphene flakes.

Flash heating plastic yields graphene and hydrogen; but you must capture the flue.

There are new plastic recycling methods that intentionally don't produce graphene that maybe could produce more plastic and graphene.

But graphene is hazardous sort of like coal ash; so IIUC if you can make graphene onsite (e.g. from unsorted 'recycled' plastics) and lock it in to glass or another substrate that avoids transport risks.

> While Kirk’s rhetoric was combative — he railed against immigrants, gender ideology and “global elites” — he operated in a democratic system and advocated for civil disagreement.

Kirk was openly happy about Pelosi shooting and advocated for a patriot to bail out the shooter.

Kirk should not be killed. He also was not someone who advocated civil disagreement or anything like that. He helped to create toxic culture that exists now and did it intentionally.

Horst Wessel was killed at time when Germany was nominally a democracy. Nazi took power only later. It was dying democracy, just like the democracy in the USA is dying.

The only thing I'd add to this (as someone with stupidly depressive and negative thought patterns), is that there are techniques that can help.

The parent comment comes off as flippant, but I am going to assume it's not intended that way.

Learning to think more positively takes an incredible amount of effort. An effort which seemingly never goes away. It just never gets easier. It's like my brain is simply wired to assume the worst, worry and of course just constantly make suicide seem like some kind of great way out. So much so, that when I was younger, I had assumed everyone just walked around constantly wondering whether it'd be easier to just die.

To this day, that's where my brain goes first. Decades of nearly daily thoughts of ending it. BUT and this is the crucial part, to me that was just always part of the noise. It's there, but it's not forcing my hand. I can both live and also constantly think that I don't particularly enjoy just existing for existence's sake and therefore death sort of seems like a viable alternative. I don't act upon it, because I'm too curious to see what's next, for the time being.

Anyway, the techniques that people are often taught in therapy sound simple and obvious, but they are harder to do than one might assume. Especially for people deep in depression.

Gratitude journaling is one of those things. It is quite boring and tedious to write down what one is grateful for in life. To write down every single good thing that happened in a day, no matter how small.

BUT, it sort of forces you onto a track of positive thought. It literally blocks / occupies thought, because it takes effort to do and focuses the mind on the positive, even if for a short period of time.

Similarly, as stupid as it sounds, sometimes it can help to simply sit up straight and smile. There is some feedback loop between pretending to be happy and then sort of feeling a bit happier all of a sudden. Doesn't always work, won't work for everyone and deep clinical depressions are a whole different ballgame.

Exercise is a pretty big one for me as well. As much as I hate it, I always feel better afterwards.

Again, the sum of various small techniques can eventually make a bit of a difference.

I've come to terms with the fact that depression is hard-wired into my brain structure and it's not going anywhere. But, I have also made a ton of new pathways that allow me to more quickly switch into more positive and grateful modes of thinking. And this, in some ways, is like a list of positive things to think, like the parent comment alluded to.

Though without all of the above, I'd also take offense at the implication that depressed people can somehow choose to be depressed and need to just stop being depressed. That notion is ridiculous and has prevailed for (what feels like) centuries of ignorance of mental conditions.

> I think "If they tried stabbing people in Texas they’d have been shot." was the most important part in the comment.

It is a cherry picked example and has nothing to contribute to the overall argument that gun ownership makes the US safe. Otherwise I can point to the many mass shootings in the US and say that would never have happened in the UK.

I live in the UK. It is objectively safer to live in the UK where we are not allowed to own guns. To us, it is absurd to claim we need guns to be safer when we look at what actually happens in the US as a result of guns.

I don't think this is really a controversial take.

That is why the argument for gun ownership actually happens at a deeper level in the psyche.

And someone said:

> It's not simply that certification costs money. It's that a lot of modern UNIX-like operating systems don't adhere to the UNIX spec. For example, the OpenBSD man pages specify the ways in which they diverge from POSIX and UNIX in the Standards section: https://man.openbsd.org/sh.1#STANDARDS, https://man.openbsd.org/awk.1#STANDARDS. Often times these are small deviations that might not matter to most people, but it means that they aren't UNIX.

Except it seems like macOS diverges, too, yet it is certified. I wonder in what other ways it diverges.

I definitely value lower power usage when idle. My desktop PC uses ~150W when idle. Sometimes I leave it on overnight simply downloading a remote file or some other extremely light operation.

It doesn't make sense that it would draw this much power. A laptop can do the same thing with ~10W.

This sort of improvement might not increase sales with one generation, but it'll make a difference if they keep focusing on this year after year. It also makes their design easier to translate into mobile platforms.

PS2, as well. But games and game hardware tend to have very different CPU requirements than general purpose workstations.

The N64/PS1/PS2 (and others) weren’t exceptional for very long, if ever, in terms of CPU power. They relied on dedicated graphics hardware, low price, ease—of-use, a business model that allowed for selling the base hardware at a loss, and devs optimizing for a fixed platform to stay competitive for 5-10 years as PC hardware improved.

Good observations! I think Embassy worked out because its creator built it with the goal of shipping smart door locks, so the components of it he uses for that workflow work well.

I think ownership sometimes works for the reason bring up: Catching errors. I suspect you will find cases where you are not as pleased you can't use something you moved elsewhere! In some cases the ownership semantics map smoothly to control over hardware; in others, it's not so good of a fit. I also suspect you are overestimating how difficult DMA and power management are without async. (In rust or otherwise) What you described is a ubiquitous embedded workflow, minus the state machine.

I seem to recall the CPU in the N64 was specced to be something like 75% of the performance of a Pentium 90 but for 20% of the price. The PS1 doesn't even have floating point. When the PS2 was released it felt like x86 was advancing faster than ever, so whatever impressive performance edge it had lasted for about five minutes.

In all cases it's hard to argue that MIPS devices were sold on the strength of their CPUs from the mid 90s onwards.
