Can't say about the content so far as I can't read it - letters are to small (so much space wasted in that boxes, still clip letters) and with browser zoom 200% blurry (on 27" 4k), using that page special zoom can't see the whole picture - neither scroll it with my Scrollpoint mouse beacuse now it's zooming :(

Why I'm forced to interact with it in some unusual way, instead of let me just have a look or print it - is it made in such way for some purpose (document programmer has some, but no DTP/design skills - so DIY) ?

I think you hit the nail on the head. Recall was problematic because of the lack of information provided when they announced it. How would it handle sensitive details like banking account pages. Can developers opt out for best security practices? How is the managed in an enterprise environment?

Once they delayed and got all their ducks in a row it's a much more solid feature. Not for everyone, but a good way to leverage your PC as a source of information that you can search without having to save everything.

The post reads a little childish to me. Very "Micro$hit are greedy and want to steal your data" level of criticism.

There is an honest way to count and that is to count the water directly used by the person or process in question. There are many other ways to count to make big scary number for clickbait article. I suppose we could also count all the water used by data center employees to take showers as "data center water usage" but that is dishonest. Those are people who exist and they are going to take showers whether they work at the data center or not.

Likewise, the power company is going to generate electricity regardless of whether a data center is there or not. The power company has various means of generating electricity available which use more or less water. The amount of water used in generating electricity is attributed to the power company, not the data center.

> I find it sad that a lot of foundational open-source software is created/maintained by trading/crypto/money laundering companies. But OTOH it's great that they at least contribute _something_ to the society!

React is unfortunately becoming more foundational than this project, and with it maintained by a company that was involved in the Rohingya genocide in Myanmar, the Cambridge Analytica scandal and so on.

This makes crypto / trading companies look like angels compared to what Facebook has done even though they made and open sourced React.

To that end, I don't see anything morally wrong with the former camp of companies supporting open source, (trading/crypto) since they didn't participate and amplify an actual genocide.

Yeah it's extremely immature, even within police agencies there's a huge variation on their ability to perform digital forensics. Furthermore, just because the feds don't like you for whatever reason doesn't mean they're going to deploy their top-of-the-line exploits against you, or detain and torture you, or whatever magic voodoo bullshit the author thinks the Mossad can do.

That GC introduces latencies of ~1000µs. The article is about eliminating ~10µs context switching latencies. Completely different performance class. The "GC-phobia" is warranted if you care about software performance, throughput, and scalability.

DoD uses languages like Java in applications where raw throughput and low-latency is not critical to success. A lot of what AEGIS does is not particularly performance sensitive.

> In addition, water is almost never wasted, only moved around.

You can literally day the same thing about energy. Electricity is never wasted, its just different afterwards.

Water use absolutely does matter, because „being moved around“ in the quantities we do, is far from trivial. Its also different than agriculture. Agriculture still has a somewhat closed local water cycle while the water used for evaporative cooling is basically gone locally.

It matters a whole lot for where you are. If you‘d do evaporative cooling with salt water from the ocean, nobody would bat an eye. The problem is that it is done with fresh water, which is becoming increasingly scarce in an increasing number of regions around the world.

It really depends on the industry, but 'bidding for a contract' does not entail a lack of competition. Yes, for certain industries, like utilities, there is no competition based on the way things are set up (and really based on the foreseeable way in which things could be set up). For things such as requisitions of commodity items, then competition is not only possible but preferable. So I disagree with your blanket characterization of things. People really need to have more nuance when discussing these things. Privatizing railroads is different than privatizing food processing.

Heh, I'm working on a blog post about this very topic. Passkeys are ... weird. There's a lot of potential for gatekeeping, where websites can indeed require you to use device-bound passkeys through device attestation, and where becoming a vendor requires interacting with the fido alliance....

I would say "I'm sure the mean well", but given that parties like Yubico benefit from not getting more competitors, the cynic in me is a bit worried.

Obligatory not a nuclear safety or health physics person, but I am a particle physicist and I deal with radiation. CPM is a rather annoying unit because it doesn't convert to dose very well. If you have external 300 cpm (eg. hair), but all of that is in the form of alpha radiation, your actual dose is essentially zero.

It's worth noting that humans are typically radioactive to the level of 3 kBq, or 3000 disintegrations per second, so if I ever realised I had 300 cpm of radiation on my skin as measured by a device that is sensitive to alpha, beta, and gamma, I probably would just shrug and wash it off. Where it might be a problem is if I am dealing with only alpha and beta isotopes, and I'm getting 300 cpm on a gamma-sensitive detector, meaning that the _secondary radiation alone_ is 300 cpm.

(Realistically, I and the radiation safety officer overseeing whatever I was doing would be in serious trouble and have a ton of paperwork, but I just mean it in the abstract)

I mean, 10 grams of potassium has ~300 Bq (that is 300 disintegrations per second) of radiation, so I think I should be able to get my hair far more radioactive than 300 cpm on a beta-sensitive geiger counter if I just slather myself in low-sodium salt from the grocery salt. The salt might be bad for my scalp, I don't know, but the radiation is fine. My point here, though, is that I don't know what equipment the 300 cpm is measured with, what the thresholds are and what the window material is, and that can change things greatly, but my non-professional opinion as the wrong kind of doctor is that it's...probably not a big deal.

We've actually used KCl as a low-level radiation source before, and we joked that when the experiment is done we can just take it home and use it to season dinner.

To put this in context, it takes about 1 gallon of water per 1g of almond [1]. And in California's dry climate, this water comes from groundwater that doesn't renew as fast as it's depleted. So the next time someone chastises you for your non-low flow showerhead that uses more than 2 almonds of water per minute, remember to put the numbers in context.

I hope you are right, but my understanding is that the high headcount in engineering could, in large part, be offset by American tax exemptions for engineering salaries and that this exemption is being actively sunset.

I assure you that photo authenticity is not an emerging field.

Using cryptographically signed photos is not even new, most of the major camera manufacturers are offering it, or are working on offering it at this point. The reality is that even with things like sensor depth data proving that a scene is in 3 dimensions, you are still able to manipulate the actors in a scene, still able to selectively include or exclude elements, still able to pick the image that seems to show something that it doesn't, still able to editorialize in a text description of a scene etc.

The time-proven solution for this is to rely on institutional reputation. While every news source has had lapses, I am far more likely to trust the reality and neutrality of, say, the AP over Fox News regardless of the presence of a signature.

Disclosure: I used to freelance for the AP as a photojournalist.

For anyone (like me) who likes their sci-fi fun and a bit cheesy I have a few recs:

Dream Park - Larry Niven & Steven Barnes: A group of pretend adventurers suit up for a campaign called "The South Seas Treasure Game." As in the early Role Playing Games, there are Dungeon Masters, warriors, magicians, and thieves. The difference? At Dream Park, a futuristic fantasy theme park full of holographic attractions and the latest in VR technology, they play in an artificial enclosure that has been enhanced with special effects, holograms, actors, and a clever storyline. The players get as close as possible to truly living their adventure. All's fun and games until a Park security guard is murdered, a valuable research property is stolen, and all evidence points to someone inside the game. The park's head of security, Alex Griffin, joins the game to find the killer, but finds new meaning in the games he helps keep alive.

The Long Run - Daniel Keys Moran: Years after the massacre of the Castanaveras genies, Peaceforcer Elite Commander Mohammed Vance still searches for the survivors. Now the gene-altered children have come of age. Denice – the world’s most powerful telepath – and Trent the Uncatchable – hacker, thief, and revolutionary – are about to come out of hiding. The world will never be the same. (It's book 2 in the series, but I'd recommend this as a stand-alone, or starting here.)

All synchronous code is an illusion created in software, as is the very notion of "blocking". The CPU doesn't block for IO. An OS thread is a (scheduled) "stackful coroutine" implemented in the OS that gives the illusion of blocking where there is none.

The only problem is that the OS implements that illusion in a way that's rather costly, allowing only a relatively small number of threads (typically, you have no more than a few thousand frequently-active OS threads), while languages, which know more about how they use the stack, can offer the same illusion in a way that scales to a higher number of concurrent operations. But there's really no more magic in how a language implements this than in how the OS implements it, and no more illusion. They are both a mostly similar implementation of the same illusion. "Blocking" is always a software abstraction over machine operations that don't actually block.

The only question is how important is it for software to distinguish the use of the same software abstraction between the OS and the language's implementation.

Cool idea! I had a look at the code and have been wondering about the sigmoid gating, it is used to add some of the q_struct and k_struct into the original key and query. But I wonder why this gating is independend of the input? I would have expected this gating to be dependednd on the input, so if the model sees something more complex it needs more of this information (or something similar). But it is just a fix, learnable parameter per layer, or am I mistaken? What is the intuition about this?
I thought cheap products get more users. I was wrong
by nookeshkarri7 | 2025-10-27 15:27:24+00:00
This month, my SaaS QRAnalytica.com hit a new milestone: $1,046 in revenue.

For a solopreneur building this after my day job, this number means the world. But the path to get here was paved with a massive mistake I kept making.

When I launched back in December 2024, my logic was simple: make it as cheap as possible. I priced it at $99. I thought, "The lower the price, the more people will sign up, right?"

Wrong. So wrong.

The first dollar didn't even come until February 14th, 2025. For months, I was dealing with low-value sign-ups and felt like I was spinning my wheels.

The turning point was a random LinkedIn post by Marc Lou. He talked about pricing based on value, not on being the cheapest option. A lightbulb went off.

I decided to run an experiment. I started raising my prices.

From $99 to $149... a few more signups.

From $149 to $249... things started to change. I attracted a different type of customer—one who understood the value and was ready to invest in a real solution.

I even tested $349.

The result? Increasing my price didn't scare customers away. It attracted the right ones. And it led directly to my first $1k+ month.

If you're building something, here's my advice: The fear of pricing too high is real, but the cost of pricing too low is even greater.

Charge for the value you deliver, not the time you spent.

Onwards and upwards!

Yes, I have. As I wrote in the sibling comments the last time just a week ago, the actual train that’s being discussed here. I’ll be again on Friday, for the return. I’ve taken multiple other night train connections before and in my experience, the quality depends to a large extend on the operator and the rolling stock. Older stock makes for less comfort, especially if not well maintained.

In my experience sleeping on the train also takes a bit of getting used to. Then again, maybe it’s really not for you - that’s ok.
Show HN: Whatdidido – CLI to summarize your work from Jira/Linear
by olism | 2025-10-27 15:28:36+00:00
I built this after spending days every year manually searching through Jira tickets to remember what I'd accomplished for performance reviews.

whatdidido is a CLI tool that:

- Pulls tickets from Jira or Linear for a date range

- Uses an LLM to create short summaries of each ticket

- Generates an overall summary to help you build your self-evaluation

The tool doesn't write your review for you—crafting thoughtful, contextual feedback still requires human judgment. It just eliminates the busywork of finding and organizing what you worked on.

Key details:

- MIT licensed, open source

- No data storage—everything stays local

- Requires OpenAI or OpenRouter API key

- Works with Jira and Linear (more integrations welcome/coming soon)

GitHub: https://github.com/oliviersm199/whatdidido

I'm releasing it now because I think others might find it useful during review season.

Would love feedback on the approach and what other integrations would be helpful. Happy to answer questions about how it works.

Regarding the "why the action is this object" part of the question, I find that the easiest way to think about it is from the Hamiltonian perspective. There you can think of it as minimising energy along a trajectory. From that point, a Lagrangian is just a mathematical trick to express the symplectic structure differently.

But if your question was more about "why minimizing something yields trajectories", I personally would argue this is beyond physics. As an empirical science, physicists have seen this kind of behaviour broadly (optics, classical mechanics, quantum mechanics) and just unified it as an overarching principle.

Finally regarding the proof to newtonian mechanics, I don't have anything handy from the pure Newtonian perspective beyond the usual "minimises the lagrangian and your equations of motions look the same". However, you might be interested in proofs which show newtonian gravity as low energy approximation of general relativity. And since general relativity has a nice action formulation, it all gets nicely tied in.

Hope this helps!

While others have pointed out his pro-Hamas rhetoric, I would also point out that we don't actually know why he was detained. The Guardian is just citing speculation from an advocacy group friendly to him. The headline is technically accurate, but it could just as well read "journalist detained after eating cheerios for breakfast".

(ICE's lack of transparency is a valid, but separate, concern, and The Guardian could have at least attempted to contact them before publishing speculation.)

Cattle water consumption should be meaningless. If a cow is drinking water from a surface water source and breathing/sweating/peeing it out in a pasture, that's the same process that would be happening if humans didn't exist.

It isn't meaningless due to industrial farming. Chickens and pigs are even more likely to be industrially farmed than cattle are.

If we lowered our meat consumption by about 90% then we wouldn't need to industrially farm meat and the 10% would be much more ecologically justifiable.

Then the problem is that the soy we've replaced our meat with is industrially farmed...
Show HN: I Made My First Movie About a Tech Startup for $2,045 [video]
by andreas-schrade | 2025-10-27 15:29:04+00:00
Years ago, I was part of a small tech startup that went through the usual rollercoaster. When it all ended, I couldn’t stop thinking about how surreal it had been: the long nights, the weird meetings, etc.

A friend of mine, who used to work in the film industry in Thailand before also moving into the tech world, had gone through similar ups and downs as a founder: burnout, crises, and the familiar feeling of questioning why we build things at all.

So we decided to make something just for the sake of building: our first movie.

It was entirely self-funded with $2,045. No investors and zero financial motivation. We simply wanted to create something we actually love!

With our entrepreneurial background, we knew getting attention for an art project would be really tough. Therefore we tried to use our startup mindset as a competitive advantage.

For example, a co-working space location that normally rents for $1,500/shooting day (we needed 4 days) became affordable when we made a deal with a smaller co-working space. We offered them photos and footage of the prodouction which they could use for their social media marketing.

During editing, we ran into something unsatisfying and we realized that Art doesn’t obey objectivity, it thrives on (personal) interpretation.

Trying to “A/B test” scenes or endings didn’t work. The feedback was all over the place.

But, once we defined a clearer target audience, it became easier to decide which voices to listen to.

Now we’re in the promotion stage, again thinking like a startup: using our network, creative outreach, and unconventional channels to get the word out.

Our movie is a fictional story inspired by real experiences and not the glossy "founder journey" version.

Here is the trailer on Youtube, would love to hear what you think of the trailer (good or bad).

I'm not particularly worried about being automated out of a job. I use the cutting edge tools for my work and they are getting incrementally better. It feels like we are plateauing. I can see a world where the LLM isn't writing code end-to-end. Instead it is writing chunks of code that I integrate. That may be more efficient than me writing out a 10,000 sentence English spec document. That allows me to express my value-add more effectively than I could otherwise. I think OP is projecting the bleak end of the possible outcomes. I don't see that happening.

Beautiful.

I believe it's interesting that these kinds of intricate, hand made objects float to the front page of the HN while at the same time many people glorify how AI can handle these jobs and can do an "arguably better job" in less time.

It's evident that these hand-drawn diagrams or any artifact with high levels of human effort (for lack of a better term) contains something we lost in today's world.

Maybe we should reflect upon that, a bit.

Nah, if I manufactured my own silicon, I'd be infinitely more hackable than I am right now - just like if I wrote my own crypto code. 99.9999% of people are going to be more secure if they just rely on publicly accessible cryptography (and silicon). Otherwise you're just going to be making stupid mistakes that real cryptographers and security folks found and wrote defenses against three decades ago.
by mikewarot | 2025-10-27 15:29:37+00:00
I believe that in the depths of the cold war, when personal computers were just showing up, it was decided, deep within the National Security Agency,that it was more advantageous to let them continue to proliferate without fostering secure Operating Systems, though they were available.

We all now live with the blowback from that decision. Most people don't even realize that actually secure computing is a possibility now, even here on HN.

This general insecurity means that anything exposed to raw internet will be compromised and therefore significant resources must be expended to manage it, and recover after any incidents.

It's no wonder that most people don't want to actually run their own servers. Thus we give up control and this .... Situation .... Is the result.

> and it's a question of "when" not "if" major sites start requiring it in the name of "safety" from bots.

I recently found a plugin that can alert to JS doing shady "fingerprint-like" activity. I did not expect it to go off quite as often as it does now.

It would seem that some sites are already asking _very_ probing questions about the browser so it's only a matter of time before they go one step further and demand proof and gate on furnishment of that proof.

My unsupported hypothesis: Gamma radiation from the blast was reaching the film that was being used to take the astronomical observations.

For this to work, though, a few things would have to be true:

1. The film would have to be stored in bulk in a place that would be (mostly) protected from gamma rays from the tests.

2. The film for that night's observations would have to already be not with the rest of the film at the time of the test.

3. The observatory would have to be close enough to the location of the test that the gamma rays would have a chance to reach it.

But maybe it doesn't have to be direct. Maybe it could be gamma rays produced by the fallout, which drifts from the location of the test to at or near the observatory.

Then you have to wonder why no more were observed after March 17, 1956. A change in the character of the film? (Either a change in manufacturing process, or a change in what kind of film was used?)
