I museum I went to many years ago had a functioning player-piano playing the Gershwin Rhapsody In Blue reproducing roll. It had an impressive amount of dynamic variation for a purely mechanical reproduction made with 1914-era technology (recording was made in 1925, but per TFA the reproducing roll technology was introduced in 1914).

2025 is shaping up to be a defining year for cloud security. As someone who’s been observing the cloud security landscape closely, I can say with confidence that we’re facing a mix of familiar challenges—now amplified by complexity—and entirely new ones sparked by AI and hybrid work environments.

Misconfigurations still top the list. Despite awareness, overprovisioned access, unused keys, and improperly set permissions remain leading causes of breaches. The answer? Automated posture management and policy-as-code tools that prevent issues before they manifest.

Shadow IT is growing—quietly. With decentralized decision-making and SaaS adoption exploding, IT teams are struggling to maintain visibility. Centralized identity and access management (IAM) frameworks and tighter app approval workflows are now non-negotiables.

AI is now a double-edged sword. Threat actors are using AI to automate phishing and bypass defenses. Security teams need to fight fire with fire—using AI-driven threat intelligence, anomaly detection, and automated incident response.

The human factor persists. Social engineering and poor security hygiene continue to be exploited. Security awareness training isn’t just annual—it must be continuous, contextual, and gamified.

What’s working for teams I’ve seen succeed?

Continuous compliance monitoring tied to business KPIs

Endpoint Detection and Response (EDR) integrated with SIEM/SOAR

An explicit Zero Trust architecture—no user or device is implicitly trusted

2025 demands more than just tools—it needs cultural transformation across organizations, where security becomes everyone's responsibility.

I'd love to see any examples you have of compile time metaprogramming libraries like Eigen or CTRE written instead in C. You can do a little of that with _Generic, but I'd generally prefer the nightmare that is templates to most of the hardcore macro magic I've encountered (e.g. Boost.PP), let alone constexpr.

I'm seeing a lot of comments here about how the history/politics part is "wrong". Would more enlightened readers care to give a summary of what, exactly, he got wrong?

My two cents: I haven't kept up on post-Arab-Spring politics, but the descriptions of Bourguiba (crafty politician, hopeless economics, then senile) and Ben Ali (thuggish, corrupt) seem pretty accurate to me.

I'm sorry but I cannot take this article seriously. Limits to Growth (and The Population Bomb) were and remain so utterly wrong in almost every detail. Like, crazy wrong. Predicting exponentially increasing costs and decreasing resources, when in fact we have experienced the exact opposite: available resources increasing exponentially and costs plummeting. Limits to Growth predicted foot shortages and population collapse around now. Instead we have a global obesity epidemic.

https://www.noahpinion.blog/p/why-paul-ehrlich-got-everythin...

What is remarkable about Limits is that anyone still takes it seriously. I struggle to think of a model that has been so thoroughly discredited as Limits to Growth has been. Jim Cramer's stock predictions, maybe.

Yeah, I've seen a lot on the "male loneliness epidemic" and I've been lonely myself sometimes but people framing it as a lack of spaces accepting of men is really confusing to me. Do people really think there's some dearth of clubs to join for men out that adding another one will make a difference?

Like I couldn't avoid being in clubs without fully dropping my hobbies. Martial arts is a good example of a generally pretty social space that's obviously very welcoming to men (I've recently been doing historical longsword fencing and there are a wide variety of weirdos successfully socializing in there) but I also do birdwatching with a group and volunteer at a wildlife rehabilitator and both of those are also pretty social.

> contrasting 200 mg of caffeine against a placebo condition

Burried in the middle:

> The participants reported moderate caffeine consumption, equivalent to one to three cups of coffee per day. All participants were non-smokers and free of drugs or medicine which could influence the sleep-wake cycle. Subjects also reported no sleep complaints, night work, or transmeridian travel in the 3 months before the recording.

> The participants arrived at the laboratory 6–8 h before their habitual sleep time and left 1–1.5 h after habitual wake up time. Bedtime and wake time in the laboratory were determined by averaging each participant’s sleep-wake cycle from the sleep diary. The total dose of caffeine administered was 200 mg (100 mg per capsule) which is considered to be moderate (equivalent to 1–2 cups of coffee) and induces significant changes in the sleep of young subjects23. Two-piece telescopic hard capsules were used, allowing the ingestion of caffeine without oral contamination, in a double-blind cross-over design using stratified randomization.

I doubt someone drinking 1-3 cups per day would feel that 200 mg single-shot is "normal." That's 2-3 cups in one go. For me, it would be like drinking it around 3pm.

I would fit the cohort. If I take a 200 mg caffeine capsule at 3pm, I get pretty fucked up, and I'm wondering what the self-reported effects were at the time they went to bed. Did they feel normal?

It sounds like this is one of those studies that are meant for other researchers, not the public, because the actual evidence is about effects that don't match daily lives. This type of caffine ingestion would be noticeable, and you'd pretty quickly dial it down if it was felt the way I suspect it did feel.

I wasn't thinking of a 16x8 array, I was thinking of an 160x80 array. Spacing your speakers too closely will have diminishing returns, but it depends on the frequency to which you want to operate. If we assume a frequency of 20kHz you should space your speakers at half the wavelength to avoid spatial aliasing artifacts, so something like a speaker every 8mm. This is especially important if the listener position is close.

This means 13000 precise delay lines multiplied with the number of virtual sound sources you want to allow for at the same time let's assume 64. At a sampling rate of 48kHz that means 39x10⁹ Samples per second. That isn't nothing, especially for a consumer device and if we assume the delay values for each of the virtual source-speaker combinations needs to be adjusted on the fly.

> If there were not negative externalities being subsidized, i.e. perversely encouraged, then growth would always be good.

That's a good start, but it's a bit more complicated.

Reasonable people can disagree what counts as a positive vs negative externality. Eg if you like to be warm, perhaps you see global warming as positive externality. (Really silly example, but you can come up with better ones.)

Also reasonable people can disagree about discounting rates. If current interest rates are very high, it can be economically rational to cut down a forest completely to get lots of lumber now, but severely damage long running production. If discounting rates are very low, then you'd leave the forest standing.

If you internalise externalities, the problem becomes less extreme, but sufficiently large differences in discounting rates will still make it surface.

> Once large corporations start making money where there is a negative sum conflict of interest, growth by definition very very bad.

Why single out large corporations? If anything, large multinationals are about the best run businesses on the planet.

Politically, we need economic growth. It is what made us "civilized". Before we had ample economic growth, the human ambition to get more wealth and power used to mean, to go to war and take all that your neighbour has. And people should not make the mistake of believing we are somehow not exactly the same people we were 100 or even 1000 years ago. People today, are still killing each other over land, for example.

So yes, the energy/climate crisis should be taken seriously, but proposing a utopia that ditches one of the major constraints on our way of life is no solution.

>> Looks like a race towards singularity, because if we don’t get there, we collapse.

We may get either; at this point the singularity outcome is slightly more probable. The problem is that it won't be a singularity good for (most) people, so from our point of view that outcome also looks like a collapse. The most "regular" collapse on the other hand could let us be and could turn into a good lesson and opportunity; though how so is purely speculative fiction (which I write).

The title mentions high doses and long periods, but let’s quantify it more accurately:

Cases of toxicity have been reported at doses as low as 21 mg per day, the recommended daily intake is 1.3 to 2 mg. The person in question was diagnosed with issues possibly caused by this after 2 years.

Edit: Clarification, the 21 mg figure isn’t from this article but from a related document released by Australian Therapeutic Goods Administration.

What? That sort of vague dismissal with likely zero reasoning behind it doesn't really deserve a reply, but here you go anyways:

Many places don't even do address validation for regular addresses, because it's generally dogshit and either too lenient to be useful, or too restrictive to not filter out lots of valid addresses. Even Amazon just checks that the postal code and city match, nothing more. You can put in an entirely made up street name and they'll happily try to ship it.

If you really want to have validation, you can add parity bits to the number, so you can validate it fully client side.

As a business you may learn an address is no good when you're trying to request and print the digital shipping label - that is if you're lucky and the provider does any validation at that point for your in-country shipment (for international shipping there's usually simply none besides checking that they can route it at least to whoever they hand it over to). Worst case you'll get a return.

For these IDs the provider should be able to tell you pretty quickly they can't route the package, unlike when the customer gets their house number in their regular address wrong, which is usually only caught once the deliveryman learns that nobody with that surname lives there. If you're lucky he'll remember you live on number 21, not 12.

In any case as an online retailer you'll already be dealing with lots of returns anyways - invalid addresses is just one of many reasons your shipments don't reach the customer. Anyone who does shipment has a processes to handle these anyways. Using numbers that can be quickly determined to be correct/incorrect should actually improve things.

So again: What are you on about?

How is this relevant, and what does is even mean?

> Everything we do, every technological step forward, is always inevitably configured within the frame of a capitalistic belief system, with the myth of growth locked in place as its central device.

Tech advancements and growth are kinda the same things tho. Being static - not growing - implies a lack of change. Tech advancements only spread if your can do cool new things with them.

I thought the time limit in Australia expired recently (as in: within the last two to three years).

As of July 25, 2022, the Australian blood donation rules that previously barred individuals who lived in the UK for more than six months between 1980 and 1996 from donating blood have been lifted.

Maybe worth double checking at your local blood donor centre. There always seems to be a shortage of blood.

Well, _eventually_ the growth might stop.

But the growth doesn't automatically mean that it happens because of the resource use increase. Growth often results in technologies that use _less_ resources: cars and lighting are prime examples.

> Are you arguing that the model didn’t predict fracking correctly or what’s your point exactly?

I'm arguing that predicting the exact point where the growth limits are reached is impossible. Especially when it's not due to something fundamental like the Sun's total energy output multiplied by the lowest possible entropy increase quantum.

Here's a "waltz" produced by a grid-lstm, a long obsolete LSTM variant:

Probably more interesting to get a feel for the failure modes of old LSTM variants than for the music, but maybe someone on hacker news will appreciate it.

We are sitting on a giant pile of matter, and we get a steady stream of fresh energy from the sun everyday.

Yes, resources are technically finite, but we are a long way away from that mattering.

Until then, there's a limit on how cheap we can get our resources---and human ingenuity is chipping away on that. But scarcely a limit on the absolute amount of resources.

> Are you arguing that the model didn’t predict fracking correctly or what’s your point exactly?

The model didn't predict anything correctly. Fracking is just something on top of people's minds now, but the model didn't take the green revolution into account, when that was already underway when they formulated it.

As a reasonably successful immigrant from Eastern Europe, mostly not true in my experience. You do have some people, ahem roma/gypsies ahem, that abuse the hell out of social benefits for example, getting them from multiple countries at the same time, etc, but for normal people, the reason they succeed is the fresh start and being an outsider in my opinion.

For older immigrants it's an opportunity for a fresh start that kicks them out of the daily monotony and puts them in the sink or swim of early adult life again.

For younger immigrants, we're mostly the top X% of talent coming from mostly well off families. Couple that with needing to be at least better than the average to compensate for your immigrant background and we either do very well, or go back to where we came from... After all with the experience of being mediocre in the west you can go back and sell yourself as a top achiever with experience in the country where the company headquarters/clients are.

A splat is basically a point in a point cloud. But instead of a gaussian splat being just a point it isn’t infinitesimally small but like a 3d gaussian where the point represent the mean. It also has color and opacity. You can also stretch it like an ellipsoid instead of having it have perfect radial symmetry.

The communists in the Soviet Union and mainland China also did some science. We also have plenty of folks in research today who are less than favourably disposed to capitalism (and growth).

> Do we have references for how correct these type of predictions were in the past about similar claims?

They have always been wrong since before Malthus.

>He said: "There was apprehension, but in all honesty, it's turned out well.

Show HN: Because Apple's daily rings are limited: App for weekly activity goals
by tobias5 | 2025-05-30 06:41:10+00:00
I build my 2nd iOS App as a new developer and I'm looking for feedback.

My idea was to build a weekly activity tracker because I was not happy with Apple's activity rings. I had 2 major problems with them: 1) Daily metrics. For me, I'm often having 7000 calories a week, but 1000 as a daily goal to have consistently is very unrealistic. I get the point of the daily motivation with the ring, but why not try it weekly or last 7 days. 2) Especially the stand metric is very useless I feel. I wanted different metics.

So the app is solving exactly those two issues for now.

It's tracking: - Minutes of vigorous and moderate exercise (based on time in heart rate zones 1-2 for moderate and 3-5 for vigorous) - Steps taken - Calories burned - Time spent in specific heart rate zones (Zone 1-5) - Distance for walking, running, cycling, and swimming - Flights climbed - Time in daylight - all your workouts in minutes

It's using as a time period: - this week (starting monday) - this week (starting sunday) - last 7 days

Visually, I'm using progress bars, with a projection if set to "this week". With "last 7 days" the goal would be to always have a full bar.

I'm not tracking any data The app is free https://apps.apple.com/us/app/weekly-activities/id6746421016

Happy to get feedback here. Thanks

In UK law, it is generally considered sex discrimination to exclude someone on the basis of their sex, unless that exclusion is a “proportionate means of achieving a legitimate aim”. It’s fairly well understood that women have sex-based needs that justify this aim, but very rarely recognized that men might have such needs too. Maybe this is one of them.

The fear will always be that male-only spaces will become centers of power and decision-making that women are excluded from. That’s where the private London clubs sit. Doesn’t seem as likely to happen in a shed, but who knows?

The linked blog post about the smallest possible valid (X)HTML documents is noteworthy, if only for the fact that a surprising amount of people adamantly refuse to believe that they are valid. Even when you think you have gotten through to them with specifications and validators, a lot of people will still think “yeah, but it’s relying on error handling though”. I’m not sure why “HTML explicitly permits this” will not be tolerated as a thought and somehow transforms into “HTML doesn’t permit this but browsers are lenient”. It’s a remarkably unshakeable position. And even the people who are eventually convinced that it’s valid still think that it is technically incorrect in some unspecified way.

> If Not Malthusian, Then Why?

> This paper shows that merely the Malthusian mechanism cannot explain the pre-industrial stagnation of living standards. Technological improvement in luxury production, if faster than improvement in subsistence production, would have kept living standards growing. The Malthusian trap is essentially a puzzle of balanced growth between the luxury sector and the subsistence sector. The author argues that the balanced growth is caused by group selection in the form of biased migration. A tiny bit of bias in migration can suppress a strong tendency of growth. The theory reexplains the Malthusian trap and the prosperity of ancient market economies such as Rome and Song. It also suggests a new perspective on the Industrial Revolution.

I think benchmark targeting is going to be a serious problem going forward. The recent Nate Silver podcast on poker performance is interesting. Basically, the LLM models still suck at playing poker.

Poker tests intelligence. So what gives? One interesting thing is that for whatever reason, poker performance isn't used a benchmark in the LLM showdown between big tech companies.

The models have definitely improved in the past few years. I'm skeptical that there's been a "break-through", and I'm growing more skeptical of the exponential growth theory. It looks to me like the big tech companies are just throwing huge compute and engineering budgets at the existing transformer tech, to improve benchmarks one by one.

I'm sure if Google allocated 10 engineers a dozen million dollars to improve Gemini's poker performance, it would increase. The idea before AGI and the exponential growth hypothesis is that you don't have to do that because the AI gets smarter in a general sense all on it's own.

At risk of speaking for the parent, I think that sentence sums it up. Specious is the fancier word for it.

These 'analyses' take a myopic view of a complex buffered system and well beyond the predictive power of the analysis.

Kind of like saying $MSFT went up 1pct today, so by this time next year it will be up 365% and in a decade its exponential growth will collapse the economy.

For a recent non-contrived example, projections of electric vehicle ownership haven't exactly followed expectations.

Whether I’m still young depends on your definition of that word, but I’m proud of my autism diagnosis, because it gave me the vocabulary to explain what I had always felt and the ability to find tools to improve my life.

I used to be dismissed as lazy, and I simply had to live with my apparent moral failure. Man, I tried so much self-improvement advice, and none of it worked.

Now I know that this is not the case, that there’s nothing wrong with me, and I found a huge community of like-minded people. Turns out there are quite a lot of self-improvement tools for autistic people, and they actually work.

(I believe many ADHDers feel the same way about their diagnosis.)
