This article says that using `transform` is faster than using `left` and `top` because `transform` is handled on-GPU, while `left` and `top` are not. This is a myth. I tried the demo page in the Firefox profiler; neither the optimized nor the unoptimized version missed frames. I tried it in the Chrome profiler; the unoptimized version missed frames, but the time was clearly labelled by the profiler as being GPU time, not reflow. Neither browser did reflows (or, all reflows were fast enough to not have any profiler-samples associated.)

The reality is that browsers contain large piles of heuristic optimizations which defy simple explanation. You simply have to profile and experiment, every time, separately.

They only surveyed 1,000 drivers? That does not seem like a good sample size for this kind of study.

If we're going to have Flock spy on our cars everywhere we go, and the cameras are good enough to track bumper stickers and dents, they should track bird poop and publish those results.

Kind of like how OkCupid used to use their data to develop and publish insights (before they sold out to the Match group).

Ahh you’re right, there are some that just initiate a connection via something like Session Manager, but those connections where AWS initiates the connection for you are logged in CloudTrail, even without data events, and root doesn’t give you any ability to directly SSH into an instance outside of those methods (you cannot, for example, use root to find out what the private keys are for logging into an instance) so we’re back to the fact that any such access would be auditable.

RSC should never have made client support opt-in. During RFC it was identified as a problem, but Shopify and Vercel pushed for an intentional breakage "for the greater good" in driving adoption.

(conveniently ignoring that they're likely two of the only platforms that will ever want to take on the complexity of a non-toy RSC deployments)

yup. So if you decide you want to have a child, you just get ready to fork out 40-80K for the birth.

Because anyone can afford that, right?

Oh, and by the way, if you are in Texas abortion is illegal. In case you didn't actually __decide__ to get (yourself, your partner) pregnant.

So it's either 40-80K or 40 years. Easy choice.

From 2023: It has been suggested that the BBB breakdown may precede cognitive decline and neurodegeneration, highlighting the critical need for further exploration of the BBB’s role in AD and its potential as a therapeutic target [22]. The BBB endothelium is a specialized system of brain microvascular endothelial cells that separate circulating blood from the brain’s extracellular fluid, maintaining the brain’s homeostatic environment [23]. The BBB endothelium plays a crucial role in the protection and functioning of the brain, allowing the selective passage of nutrients and molecules essential for brain function while simultaneously preventing the entry of potentially neurotoxic substances [22].

Also interesting: the two-hit vascular hypothesis of AD suggests cerebrovascular damage (hit 1) as an initial insult that is self-sufficient to initiate neuronal injury and neurodegeneration. Additionally, it promotes the buildup of Alzheimer’s Aβ toxin in the brain (hit 2)

> How does it feel to have to substitute them into your name?

It does not directly bother me but can lead to downstream inconveniences. Public services (in Germany) ime don't like mismatches in identifiers, especially inconsistent ones. If it is required then it might sometimes take more than one application (with a small explanation on why the mismatch is there).

As another example, if ä is substituted for ae in shipping addresses then automatic tracking for packages by DHL via my customer account breaks (as the address is not identical anymore).

> who assume that married couples, and parents/children all have the same last name and hit roadblocks when that expectation does not match reality

Speaking as someone whose mom didn't change their name when marrying my dad, with a sister who didn't change her name when marrying my brother in law, with a wife who also didn't change her name when she married me, I think this problem is overblown. I have yet to encounter any actual issues with this.

Sometimes people will assume we aren't married and/or divorced, and people will often call me by my wife's last name and vice versa, but it has never caused any actual problem. Never had any system that assumes we have the same last name. So many people live in blended families anyway, that very few systems/people make these assumptions any more.

See, this is not making me feel good about the deutchland ticket.

My understanding is that the Bavarian day ticket can still be purchased as a piece of paper from a kiosk at the station and we would print our names on it (2 adults, 3 kids). This seems so much easier than worrying about starting and stopping a subscription!

> Ok, so we already have your standard

Who is "we"?

I don't know what you are going on about. Empirical evidence is one thing, mechanism is another source of knowledge by which we can shape public health policy. While empirical evidence is valid only for the situation in which it was obtained, mechanism is universal.

For example, we mandate wearing seatbelts in cars in the name of public health. It is however not necessary to do seatbelt on/off RCTs with actual people. How we know that this is beneficial: Because physics, verification through crash tests (with dummies), and because we know that seatbelt mandates increase the frequency of people wearing them.

Going back to the original question, it was clearly shown in observational studies that giving children sweetened food is bad: Childhood dietary habits shape lifelong food preferences, and preference for sweet food leads to worse outcomes regarding chronic diseases later in life. This has been shown in lots of research, both in humans and in animal models:

https://doi.org/10.1126/science.adn5421

https://doi.org/10.3390/nu16030428

https://doi.org/10.1093/chemse/bjr050

With randomly adding or substituting sugar with artificial sweeteners there is however no empirical evidence nor known mechanism which supports a public health benefit. In fact the mechanisms we know from animal farming suggest a detrimental effect.

This is a total red herring, x86 has over 30 years of backwards compatability and the same goes for the basic peripherals.

The real reason for software churn isn't hardware churn, but hardware expansion. It's well known that software expands to use all available hardware resources (or even more, according to Wirth's law).

The nature of human organization and political structure is based on a weighted asymmetry of power where some autonomy is given up in exchange for a greater survive-ability. This is inherent in the basic understanding of the social contract theory.

The structure of the system itself has flaws in the same way, because of that asymmetry, on the positive side it allows someone capable to do great things with the resources available, but equally when you have a rotten cancerous parasitic crop of leaders, it spreads that corruption and toxic love everywhere just like Hexxus as he gets out of the prison.

American's aren't on board when that sacred promise is broken by oathbreakers. It does take time for the abuses to accumulate before a population will be spurned to action, it always happens like this during the fall of empires.

The environment becomes so disadvantaged and rife with abuse that the average person understands that there is no out, you can't get away, there is only through. The same as was brilliant depicted in Andor.

People will starve, but the abuses are necessary to mobilize the population to action. It doesn't happen otherwise because the consequence is too great (existentially so).

Cool. Operationally, are you using some host-resident non-shallow repo as your point of centralization for the containers, or are you using a central network-hosted repo (like github)?

If the former, how are you getting the shallow clones to the container/mount, before you start the containerized agent? And when the agent is done, are you then adding its updated shallow clones as remotes to that “central” local repository clone and then fetching/merging?

If the latter, I guess you are just shallow-cloning into each container from the network remote and then pushing completed branches back up that way.

For those looking for a fix to US healthcare I think it's something like this:

- (user incentive to reduce cost) insurance is structured as co-pay of [20+]% on all expenses, no exceptions

- (price transparency) require healthcare providers to quote upfront for care, via API/website/phone/in-person. Price paid by anyone is the same except for expenses related to billing. E.g

https://surgerycenterok.com/

- (create competition) enable creation of small scale clinics, testing facilities, and laboratories

And for God's sake, get the government out of it!!

One (social) system that may work well is the South Korean one: private provision of healthcare services; government run insurance scheme with mandatory payments by those that can afford to pay

https://en.wikipedia.org/wiki/Healthcare_in_South_Korea

I love markets, but health insurance really is a tough one given the govt can't seem to let people make their own mistakes on healthcare, so I think it might make sense to make it govt run.

Edit: the thing to acknowledge here is that it probably won't push the frontier of healthcare as much as the current US system does, but at least it would be high quality and affordable (not people's largest or second largest expense item).

The key bit of the press release:

> After February 18, certain features — including access to integrated music services like Spotify and TuneIn, as well as multi-room playback — will no longer be available. However, if your SoundTouch product supports Bluetooth®, AUX, or HDMI, you’ll still be able to enjoy high-quality audio playback from connected devices.

The worst thing with C pointers was for me that the asterisk is inexplicably used both to declare a pointer and a COMPLETELY different operation of dereferencing a pointer.

I still don't understand this decision. I think it should've been like int^ p = &i; ... or ... int i = *p;

Everything clicked ironically when I went even deeper and studied assembly language. Then following pointers to data vs just reading pointers becomes very clear and explicit.

> Sure wish there was a system that just did that, without trying to also generate insane profits off it.

Health insurance companies in the US must pay 80% of premiums to providers. All their overhead (e.g. their accountants and actuaries and so on) comes out of the remaining 20%. What's left is their profit. People have this fantasy that all the money we spend on healthcare is secretly going to greedy insurance companies while doctors struggle to get by. But insurance company profits are a drop in the bucket.

The real villains are the doctors who recommend expensive MRIs and act like it's a complete surprise that the bill they give you is so high. And then go lobby the government to limit their competition. I would love to have a doctor in france look over my radiology and tell me if I have cancer. But that's illegal, I need to hire an American. Coincidentally, the average radiologist in San Francisco makes $660,000/year (about $400/hour).
Show HN: ai-tokenizer – 5-7x faster than tiktoken with AI SDK support
by kylecarbs | 2025-10-09 22:39:58+00:00
Hey HN! I built an AI tokenizer that's 5-7x faster than tiktoken using pure JavaScript - no WebAssembly needed.

Born from frustration with existing packages:

- Existing libraries don't support AI SDK messages and tools. Tools consume massive tokens (549 for adding a basic Claude tool [1]), but there's no way to count them. ai-tokenizer has native AI SDK support with per-tool breakdowns.

- Most models don't publish exact tokenizers. We run real API calls at build-time to find the most accurate public BPE tokenizer for each model, then apply calibration weights to achieve 97-99% accuracy [2].

- WebAssembly isn't necessary for great performance and reduces portability. ai-tokenizer precompiles BPE vocabularies into optimized hashmaps, achieving 5-7x faster performance than tiktoken [3].

Not to mention that it's unreasonable to levy that accusation even to someone who buys a Tesla today. Doing business with someone does not construe agreement with everything that person does. And while it's everyone's right to decide that they, personally, don't wish to buy a Tesla on the basis of Elon's beliefs, it's nobody's right to demand that everyone else must do so or else they're a Nazi.

What gets me is the people who decide not to call me by the name I specifically introduce myself with.

I have a nasal vowel in my name that, so far in my life, only French and Portuguese speakers have pronounced properly.

I learned English in the US young enough that no one guesses I'm not native, and I anglicized my name so that it could be pronounced easily. It is what I go by.

I introduce myself with this adopted pronunciation. People often ask me how to pronounce it in French, so I tell them, but reiterate that I go by the anglicized pronunciation.

Inevitably, those folks start using their wrong attempt at French and I have to correct them and tell them I go by the anglicized pronunciation.

Edit: strong feelings had, obviously.
Prevented from reading/verifying Bitcoin-core tx/block encoded msgs
by cc-d | 2025-10-09 22:42:10+00:00
Why can I not find an easily accessible+searchable public resource for these tx/block encoded messages?

I went to fetch this data for my own use, discovered it had been deleted, and have had my entire day wasted today by an "intelligent" agency treating this publicly accessible and auditable data as if it contained state secrets.

I am one man with ascii, being targeted by a sophisticated entity, who has apparently hired some very unsophisticated people, preventing me from making publicly available data public to the internet. Which I wasn't even interested in making public in the first place.

It's too stupid to be believed. That multiple levels of compromise, including my own nervous system and perception, would be utilized to prevent me from doing this.

Alice: "Bob, I know you're very proud about your neural network calculator app, but it keeps occasionally screwing up with false algebra results. There's no reason to think this new architecture will reliably do all the math we need."

Bob: "How dare you! What algebra have humans been verified to always succeed-at which my program doesn't?! Huh!? HUH!?"

___________

Bob's challenge, like yours, is not relevant. The (im)perfection of individual humans doesn't change the fact that the machine we built to do things for us is giving bad results.

The coat of A.I. gloss is giving the administration runway to double down on bad ideas: America’s effective overall tariff rate is nearly back to the levels announced in April, the vice president has called for the administration to be involved in the Federal Reserve’s interest rate decisions, and Mr. Trump fired the head of the Bureau of Labor Statistics after a disappointing jobs report.

The situation is worse than having all of your economic eggs in one basket. It’s closer to putting all of your eggs in one basket and stomping on all the other baskets.

There are signs that the non-A.I. economy is under duress. As economists predicted, tariffs are pushing up inflation and dragging down growth. Hiring has stalled. Jobs are particularly hard to come by for young people entering the labor market; youth unemployment is at 10.5 percent, a level not seen in nearly a decade, absent the pandemic.

I created a new account about two months ago to see what’s true about the tales that it’s absolutely crazy what’s there as a new account. And it’s pure racism. At least half of tweets either about some blacks who did something bad, or how whites are suppressed, and we are right. And the whole experiment started by blocking Musk and co, so the intent wasn’t even there. It had a honeymoon phase for a few days, where it seemed the hearsay to be not true, so I didn’t visit for a while. Then I went back after a month, and it’s a racist “paradise” completely since then.

The IRS has some guidelines that they use to decide what is “reasonable” but they don’t give out whatever actual formula or process they use to determine this. It’s supposed to be based on industry averages (more or less) but in reality it’s hard to determine what exactly that means. Generally you are “safe” paying in an industry average range, but if outside that range you need legal and accounting support to back up your own assessment.

FWIW the article says this:

>"The long-term effect comes from restoring the brain’s vasculature. We think it works like a cascade: when toxic species such as amyloid-beta (Aβ) accumulate, disease progresses. But once the vasculature is able to function again, it starts clearing Aβ and other harmful molecules, allowing the whole system to recover its balance. What’s remarkable is that our nanoparticles act as a drug and seem to activate a feedback mechanism that brings this clearance pathway back to normal levels,”

>...

>Normally, the protein LRP1 acts as a molecular gatekeeper, binding to Aβ and transporting it across the BBB for elimination. In Alzheimer’s, this system becomes fragile, leading to Aβ accumulation. The supramolecular drugs mimic LRP1 ligands, binding to Aβ and initiating its clearance, effectively resetting the system and restoring vascular function.

So we may be lucky in that addressing the plaques as a symptom does indeed (allow for) repair of the underlying cause. I guess the question is how long the benefit lasts. What triggers the negative feedback loop in the first place? The article claims long term improvement for the mice, which were genetically programmed for amyloid production. (So maybe not an accurate simulation of the root cause, but perhaps actually more of a steel man test.)

Allowing preferences or downloaded videos to be stored in local storage.

Downloading from YouTube is hard, Google keeps trying to kill yt-dlp. You can download manually from your own site using a web browser, but the app wrapper would make it easier to search by metadata ("Find ICE videos from my town") and to make sure you don't accidentally download the same thing twice.

Plus YouTube might take those down for ToS violations sooner or later.

Anyway it doesn't matter - We should have the right to have apps like this and make them available to the general public. If you can't get it from the App Store, and you can't install an apk on Android, and you can't install an alternate store trivially, then it's as good as dead.

Being anti-vaccine is political brainrot in the same way being pro-crime is. Holding false political beliefs is a good way to bump up your expected mortality rate as an individual. Presumably there are evolutionary reasons for believing the lies of your tribe, so the mortality bump can't be very large, but it is definitely measurable.

The fabric wrap is idiotic. Insanely stupid. Let's have an expensive fabric-covered robot wash dishes covered in food. Genius. It's a good thing those "dirty dishes" were already perfectly clean. I doubt this machine could handle anything more. Put it in a real commercial kitchen and have it scrape oven pans and I'll be impressed.

What is your feedback in regards to battery? Android have been exhausted in development to optimize battery usage but I'm reading linux phones don't really care that much so you end up with a dead phone in less of a day.

Has a power user, what has your experience been on that topic?

I'd switch my phone to linux on a heartbeat because android apps seem compatible enough nowadays to run there too but battery is always the pressing limitation.

You did nothing from their point of view except waive having them cover the claim, thusly leaving more money on their hands to be managed longer. Your "price discovery" isn't something they aren't aware of. On the contrary, their surveillance/clinical team have been crunching the numbers and making unilateral decisions on how the population is best guided to drugs based on their bottom line benefit to the insurer.

You don't really factor into it except as an actuarial data point. But you might have kicked off an overpayment check back to the consumer in 12 months because golly gee, those pesky regulations! Don't worry though, you can hand it back because the premiums went up again!

This is stunning English: "Perfect setup for satire.

How can it intuitively know what "traumatic over-training" should mean for LLMs without ever having been taught the concept?
