Right, RAPL just reports a total power usage figure for the whole CPU. The authors then develop a model which they believe splits that total into multiple components that correspond to parts of the CPU. This is possible because CPUs provide performance counters that measure what the CPU is actually doing. For example if you write programs that are very similar but have different ratios of cache hits and misses then they’ll draw different amounts of power. You can use those differences to devise a formula for the amount of power used by the cache.

And indeed, they give their formula in section 4.2:

P_package = 6.05 + cycles/second × 1.63×10⁻⁹ + μops issued/second × 2.15×10⁻¹⁰ + μops decoded/second × 1.40×10⁻¹⁰ + L1 hits/second × 4.35×10⁻¹⁰ + L2 references/second × 4.05×10⁻⁹

You can see that the power used by the whole package is the sum of six terms. The values that the calculated for those six terms for each of their benchmarks are given in table 4. The 22W figure for the core(s) is just based on the frequency the CPU is running at.

This should make WYSISYG HTML/CSS editors possible again.

Here's a thought. Build a WYSISYG tool like that. HTML/CSS only. Round trip; that is; it reads its own HTML/CSS and works on that, rather than using some separately stored representation.

If you want to use Javascript with this, it has to be inside a manually edited IFRAME or FRAME. If you have Javascript, it's probably for interacting with a server or doing something graphical. Or, more likely, for ads, tracking, and such. Not for layout.

We're not "too important." All a union would do is create extra problems for us.

There are two possibilities:

a) This is a large scale administrative coordination problem

b) We don't need as many software engineers.

Under (a) unionizing just adds more administrators and exacerbates the problem, under (b) unions are ineffective and just shaft new grads or if they manage to be effective, kills your employer (and then no one has a job.)

You can't just administrate away reality. The reason SWEs don't have unions is because most of us (unlike blue collar labor) are intelligent enough to understand this. I think additionally there was something to be said about factory work where the workers really were fungible and it was capital intensive, software development is almost the polar opposite where there's no capital and the value is the theory the programmers have in their head making them a lot less fungible.

Finally we do have legal tools like the GPL which do actually give us a lot of negotiating power. If you work on GPL software you can actually just tell your employer "behave or we'll take our ball and leave" if they do something stupid.

> Are you tired of being required to run `sudo apt update` just before `sudo apt upgrade` or `sudo apt install $PACKAGE`?

Is `sudo apt upgrade --update` really that big of a QOL improvement over `sudo apt update && sudo apt upgrade` (or an alias for the same)? Or is there a difference in terms of performance or something else that I'm missing?

At DefCon 26 (25?) I attended two presentations that scared me:

1. there was a presentation about several admins in a hostile country who had been arrested because someone from Harvard pinged a server they ran as part of IPv4 measurement. The suggestion was to avoid measuring countries with strong censorship laws to prevent accidental imprisonment of innocent IT.

2. similar presentation about ToR project struggling to find fresh egress/ingress addresses. Authoritarian countries were making lists of any IP addresses that were known ToR IPs and prosecuting/imprisoning users associated with them as a result of traffic on those addresses.

I would be extremely careful trying to bypass authoritarian restrictions unless I was 110% confident what I was doing.

It's quite a lot more important to diversify funds for procedural risk than bank failures, although SVB certainly illustrates that they do happen.

More likely, the bank will put a ~$1b hold on your account while they investigate suspicious transactions, and your options are to whistle, sing, scream, or twiddle your thumbs until they are done.

So having 4-5 total accounts, ideally unrelated to each other in terms of legal owners (differently-named subsidiaries are usually the way to go, I understand, though I am far from an expert in such matters), will enable you to continue to operate your business while bank A does compliance on your accounts.

If you run into a situation where banks A through F all put holds on your account, you need a good RICO lawyer or equivalent. Different class of problem, and different likelihood of happening, and the kind of thing a great CFO plans around.

Software development is one of the listed industries. Well before AI we have seen that few companies wanted entry level devs due to the training and such.

Reducing in call centers has been going on for a while as more people use automated solutions (not necessarily AI) and many of the growing companies make it hard to reach a real person anyways (Amazon, Facebook, etc). I feel like AI is throwing fuel on the existing fire, but isn't as much of a driver as the headlines suggest.

And they still don't have clean tap water. Like anywhere. Even tier 1 cities. Outside of a few routes The high speed trains are less convient than airports (but due to subsidies much cheaper). Quality of construction is horrible and by local standards house prices are extremely high. Basic Healthcare is pretty good but many procedures (i.e. hospitalization) are out of reach for the majority of the population. White collar Fraud is rampant (my friend had his bank account frozen because his name sounds like someone else). Their top tier apps are often crashing (seriously Chinese people have all sorts of tricks to force reboot an app) and overall not up to western standards.

China is great but it is still a middle income country like Thailand or Malaysia. It's sheer size means that there will be pockets of innovation in a sea of what is overall suboar by western standards. There is definitely things that the west can learn from china (like the value of hard work and getting things done) and some of their tech (like batteries ) is leading edge but we have to put things in perspective. Every civilization will have it's advantages and disadvantages. There is no superior system. For the west (especially Europe) we need to embrace change. That is something that the Chinese truly lead the world.

Incorrect title: ".... in the US" missing. No guarantee, maybe no possibility that such restrictions will be in non-US countries. Perhaps we'll just a whole lot of foreign trips, or (somehow) smuggling nasal or physical vaccines.

Fortunately, COVID doesn't seem as bad now, but if the MMR and other childhood vaccines, flu shots, shingles shots, ... End up with similar restrictions, people might not want that aspect of the 50's and 60's to return. Sterility, deafness, ... lots of possible effects from childhood diseases if they reappear en masse.

This article has lots of nice stuff in it but ... that first example in the tweet at the top,

cool-thing { display: flex; &[shadow] { box-shadow: 1px 1px #0007; } @media (width < 480px) { flex-direction: column; } } and html like <cool-thing shadow>wow</cool-thing>

I pasted it into a file and it doesn't work. I honestly didn't expect it to work. I thought you needed more to get a cool-thing element but in any case, it's not encouraging to see the first example fail. Am I missing some context?

my bad - I think it was just subtle and I thought it wasn't doing anything. Thanks for all the replies

American workers are truly under attack from all sides. H1B. Outsourcing. What's left? The blue collar manufacturing is mostly gone. White collar work well on its way out. Why is our own government (by the people for the people) actively assisting in destroying American's ability to get jobs (H1B)? Especially in these conditions. I'm no racist or idiot but it's unacceptable. I didn't expect the gov to actively be conspiring with big corps to make my economic position weaker. Unbelievable breach of trust. We need to demand change from our government.

Common sense:

- The compute requirements would be massive compared to the rest of the industry

- Not a single large open source lab has trained anything over 32B dense in the recent past

- There is considerable crosstalk between researchers at large labs; notice how all of them seem to be going in similar directions all the time. If dense models of this size actually provided benefit compared to MoE, the info would've spread like wildfire.

How would it behave? The standard as written doesn't suggest any appropriate client behaviour.

It explicitly doesn't have to mean deprecation, the standard says it could also be returned from any short-lived resource. There's no way to see if the header applies to the whole server or just the specific resource or even query parameters, and no way to deduplicate to ignore known warnings.

I'm reminded of what we did to the pug, which used to look like this:

Some breeders are trying to breed these traits back in, yielding the "Retro Pug" unofficial breed. Even the old pug is quite a heavy hand we've exerted on dog evolution.

Let's read the paper instead: https://digitaleconomy.stanford.edu/wp-content/uploads/2025/...

It presents a difference-in-differences (https://en.wikipedia.org/wiki/Difference_in_differences) design that exploits staggered adoption of generative AI to estimate the causal effect on productivity. It compares headcount over time by age group across several occupations, showing significant differentials across age groups.

Page 3: "We test for a class of such confounders by controlling for firm-time effects in an event study regression, absorbing aggregate firm shocks that impact all workers at a firm regardless of AI exposure. For workers aged 22-25, we find a 12 log-point decline in relative employment for the most AI-exposed quintiles compared to the least exposed quintile, a large and statistically significant effect."
Show HN: A natural language search interface to ETF (and deep insights on each)
by GodelNumbering | 2025-08-29 00:38:42+00:00
Main features:

1. Search for ETFs using natural language queries like "find me ETFs that invest in bitcoin with low expense ratio" or "find all ETFs managed by cathie wood"

2. Multilingual search (results are all English though)

3. All source data straight from the SEC filings parsed into millions of lines of clean training text, no middlemen which allows us to do things that rely on semantic document understanding

4. Qualitative analysis of every ETF that answers questions like 'what are pros and cons of this etf', 'what is the detailed breakdown of expense ratio', 'how exactly does this ETF gets its exposure' and a lot more!

We worked really hard on this one, would love to get feedback, thanks :)

Language barriers: The outsourced workers I know use AI to help them ask and answer questions about things in English they don’t perfectly understand because English is their second language. They use it to write better English from English with grammatical mistakes

Knowledge: True to an extent, but my assumption here is that it would be used to fill in gaps or correct misunderstandings. Not wholesale doing my job. At least that’s often how I use it

Hahaha, this drug interaction nonsense is what online people tell each other. It isn't even real. It's like "nice trigger discipline" or "the postal police don't fuck around" and shit like that. Just something that is not true but for some reason is internet urban legend.

Retail pharmacists are human vending machines. You don't need AI. It's a computer prescription written by a far more qualified human which is then provided to a nigh-illiterate half-wit who will then try as hard as possible to misread it. Having then misread it, the patient must then coax them out of their idiocy until they apologize and fulfill what's written.

Meanwhile some Internet guy who gets all his information from the Internet will repeat what he's heard on the Internet. I know this because anyone passingly acquainted with this would have at least made the clarification between compounding pharmacists and retail pharmacists or something.

> they mean illegal aliens are being detained to be deported to their home countries

Are you sure about this? Didn't the Supreme Court recently decide these people can be sent to a third-party nation? [1]

> When people used to say "disappearing people off the streets"

Disappearing happens in real life, not just in "1984". It doesn't mean everyone pretends the person never existed, just that their current status and location is completely unknown. This kind of "not knowing" seems really common with the current administration, with lawyers mentioning being unable to find or talk to their clients. [2]

> but that the detention centers get honest-to-god marketing names ("Alligator Alcatraz")

Just because you know of a detention location ("Alligator Alcatraz") does not mean you know who is there and for what reasons. Without that transparency, bad shit can get ignored or swept under the rug.

Substack seems to have done an incredible job allowing people to monetize their blogs. Maybe Substack themselves aren't profitable but the authors certainly seem to be doing well.

As someone who's subscribed to a lot of substacks the thing that brought me there was the availability of asynchronous reading (mail, rss newsletters.) I'm sure I'm not alone in disliking the actual site itself.

Once upon a time my wife went to close a bank account in Italy.

She went to the post office which is also a bank in Rome. She asked to closed her account. She was told that she needed to go to the branch where she opened her account in Florence.

We rented a car and drove to Florence.

When we arrived at the bank in Florence, the teller informed us that we would have to come back “domani” which is Italian for tomorrow because the only person who could help us was the banker who had originally opened the account for my wife when she was a student many moons ago.

We came back the next day and met the banker who immediately recognized my wife including recanting that she was an artist. He informed her that he could not close her account, she would have to speak to the Director of the bank.

We waited in line for the director of the bank but we were told it was too close to the end of the day and the bank was out of money so we’d have to come back… Domani.

Domani arrived and my wife again waited. The Director willfully ignored her for 2 hours and it wasn’t until my wife began to cry that the Director finally called her over and allowed her to close her account.

This for €2500. That was a balance that meant a lot to us at the time.

I will never forget banking in Italy.

My dad headed up the redesign effort on the Lockheed Martin side to remove the foam PAL ramps (where the chunk of foam that broke off and hit the orbiter came from) from the external tank, as part of return-to-flight after the Columbia disaster. At the time he was the last one left at the company from when they had previously investigated removing those ramps from the design. He told me how he went from basically working on this project off in a corner on his own, to suddenly having millions of dollars in funding and flying all over for wind tunnel tests when it became clear to NASA that return-to-flight couldn't happen without removing the ramps.

I don't think his name has ever come up in all the histories of this—some Lockheed policy about not letting their employees be publicly credited in papers—but he's got an array of internal awards from this time around his desk at home (he's now retired). I've always been proud of him for this.

I find the dish detergent hypothesis more compelling than I used to - before moving to Australia. Here, I've noticed that almost nobody rinses the dishes after washing them (something I have always done). Curious what others do in different locations/cultures. Seems pretty obvious that consuming surfactants, triclosan, phthalates, alkaline agents, synthetic fragrances and dyes is not a great gut health strategy.

Given the 2.1kg after detaching the graphic module and the seemingly large battery capacity for on the go sessions, it's so close to a laptop that fits all my use cases.

Although from what I've read 8GB of VRAM seems insufficiently near-future proof, so I've always been eyeing 5070ti+ laptops. I wonder if there's any technical blocker that prevents offering 5070ti or the amd equivalent.
Show HN: CleanerAudio – AI to clean and transcribe audio
by EdwinJr13 | 2025-08-29 00:45:19+00:00
Hi HN,

I was making family vlogs but the audio was ruined by wind noise. Existing tools felt clunky or expensive, so I built my own.

https://cleaneraudio.com/

CleanerAudio lets you: • Clean noisy recordings • Transcribe audio or YouTube videos • Summarize long videos • Download YouTube audio as MP3

Built with React (Vite), Prisma, Postgres, and AI models for noise reduction, transcription, and summarization.

There’s a free tier — I’d love your feedback on what works and what doesn’t.

Is this a moderated debate?

And that's not a false dichotomy? If I say which sport is more exhilarating to watch football or basketball? It's not a false dichotomy and it's weird if someone were to butt in with "What about baseball? Why didn't you mention baseball? What about soccer, what about tennis, this isn't a fair discussion!" I wasn't saying and didn't even imply those are the only options they just happen to be the ones we're talking about and it would be absurd to bring in the thousands of other sports to figure out which of the two is more exhilarating to spectate.

Tokyo has been considered a high tech utopia for a long time no one is surprised by its modernity (similar with Hong Kong) whereas China over the last decades has been portrayed as being little more than poor starving farmers and slave labor in worn out factories, and that juxtaposition is what makes it an interesting point of contrast.

Also I did see a barrage of articles praising Japan in the last few decades. There's literally multiple terms for westerners who are obsessed with Japan.

Also if it hasn't been unique to China at all (although I never said it was) why doesn't the country with a similar population and similar location (India) seem to have the same sort of reduction in poverty, economic prosperity, high tech buildings, and extensive modern transportation?

Hey, I’m Yoan. I started CleanerAudio because I just wanted my vlog audio to not sound terrible. Wind noise killed it, and I didn’t find any simple fix.

Happy to share more about the tech if people are interested.

As an engineer, that slide looks completely reasonable to me. Its purpose was to communicate technical info, which it did adequately. Keep in mind that the subject matter is highly technical, given that we're literally talking about the Space Shuttle, and more than a high school level of reading comprehension is heavily implied. If the NASA personnel weren't competent enough to review technical data without a pithy summary, that's on them.

I would expect it to be almost tautologically true. It's the easiest to implement, and the most deployed. It has to be the most used, even if a lot of people don't know they're using it.

It was the original success of LLMs -- code autocomplete. All of the agentic coding have autocomplete under the hood. Autocomplete is almost literally what LLMs do + post-processing.

The core of the identity problem is, “how can someone ban you personally without being able to identify you?”, and so far as I know, “a trusted third-party checks your identity and issues you an identifier” is the best we’ve got - but of course those identifiers can be enriched, so you end up needing a single centralized third-party that can issue identities and also honor bans for “the individual behind identity X” from specific sites by site request, while being audit-proven to actually enforce those bans upon me regardless of how many anonymous identities I choose to generate and use. (If you don’t run this as a monopoly, either they all pool their user-operator banned identities lists to prevent ban evasion, which will eventually leak, or they will be compelled to someday later down the road when they lose the inevitable monopoly lawsuits.)

It’s not difficult to solve this problem — the database schema and queries are dead simple! — it’s just exceedingly difficult to succeed if you're not a passport-issuing entity or an authorized monopoly of such.
