It's definitely the beginning of the end of Google Search IMO. Extremely small sample size, but me and many people I know have started running the majority of searches that end in a question mark (actual questions) in an LLM, and not Google's LLM. Google is only used as a sort of phone book - when I need to look up the URL of a site by inputting the name, or when I want to find a particular article I previously read. I would say my usage of Google has reduced by about 75% (seat-of-the-pants estimate). It's just better to do it this way, and I have to imagine that this sentiment will spread.

Google will have to survive on other products, like YouTube. I see a massive contraction of their employee base in the not-so-distant future. Low-return products that are subsidized by the massive revenue of search will likely be cut as well if they can't be monetized more effectively (which will ruin them).

> If you can't tell when a big expensive llm is subliminally grooming you to like/dislike something or is selective with information

I mean, I can tell when a page contains advertisements, but I still use an ad-blocker.

The point was not to help me detect when a response is ad-heavy, but to stop me seeing those ads at all.

> Arms race?

Possibly. Like with ad-blockers, this race can't be won by the ad-pusher LLM if the user uses the ad-blocker LLM.

The only reason ad-pusher websites still work is because users generally don't care enough to install the ad-blocker.

In much the same way, the only reason LLM ad-pushers will work is if users don't bother with an LLM ad-blocker.

Have you tried introducing a food scale? Not with the intent of changing your portions or anything like that - just out of idle curiosity to confirm how much you're eating?

I found that I was eating over double the amount of nut butter that I was estimating once I started weighing it. After a couple of months I was able to go back to eyeballing it while remaining accurate.

A lot of wisdom suggests being +/- 300 calories from your TDEE to cut/bulk. Three tablespoons of peanut butter is ~285 calories. So it's entirely possible that something as small as an estimation error is responsible for whether you're gaining or maintaining. Same goes for eyeballing cooking oils, seeds & nuts, and, to a lesser extent, processed carbs.

I read your deflections of how it’s totally not the same political groups advocating for all these things and your thinly veiled personal attacks.

You speak of not wanting censorship and wanting there to be balance, but balance of what and how? Without actual measurements and quotas on game content there can be no balance and it’s just censorship to please the side which has the most political influence, for video games this is obviously the far-left right now.

If it’s not about censorship and about having choice, why are there complaints when existing games that have attractive character come to western market ?
Google Play Games usernames expose email prefixes by default?
by Modestcor | 2025-07-24 14:53:41+00:00
I noticed something odd with Google Play Games: when you create a profile, your default public username is just your email prefix (the part before @gmail.com).

For example, if your email is coolguy123@gmail.com, your visible username becomes "coolguy123" by default. Most people never change it, especially casual users or kids.

Because of that, when you look at public leaderboards, you can easily guess full Gmail addresses just by reading usernames. It's not a data breach, but it does feel like a privacy oversight that makes email guessing way too easy.

Is this something that should be reported? Has anyone else noticed this? Wondering if this could be exploited or if it’s just a harmless default.

Even 5% more expensive means 80% of people buy the taiwan version for $475 instead of $500.

20% more expensive and 99.9% of people buy the $500 one instead of the $600 one.

Never make the mistake of falling for people's virtue signalling and pay attention instead to how they actually apply those virtues (spoiler: saving money is the #1 acted upon virtue, being far stronger than any other).

> It's also a form of light racism that targets foreigners/migrants by imposing more difficult bureaucratic requirements and costs on them compared to by birth citizens.

How is having a different process for foreigners racist? Criticize it if you will, but calling it racist is crazy. Even "light racist" - whatever that means. Bureaucracy in Germany is notoriously slow for all people. Foreigners going through a different process makes it worse. I understand that. Nevertheless racism is a problem that exist and is prevalent (Germany is far from an exception here) and IMO you make it more difficult to improve in the right direction by (seemingly) calling every problem of foreigners racist.

Throwing good money after bad sounds like something governments are prone to do. Dysfunctions tend to grow as those who benefited from corruption have more money now to spend on more corruption.

Since Intel has been mismanaged for so long I don’t know how many good lower level employees they managed to retain, I doubt much would be left if they properly cleaned house.

When my manager wanted to put me on a pip, an experienced HR friend recommended me to speak to an employment lawyer asap. They would help for a relatively small fee, and a percentage if they win. In many countries PIPs are subjective, and courts nudge to protecting employees. A lawyer can help you prepare to document and catch errors. It doesn't solve your problems but at least you have the chance to get a premium for your frustration.

This was not in the Netherlands, so things might be different, but probably similar to a certain extent.

Nobody has done low-nm lithography on anything but silicon, on integrated circuits.

The reason is that such integrated circuits could not compete in cost, so developing all the fabrication equipment for them would not be worthwhile.

On the other hand, on special discrete devices, e.g. microwave transistors, and on experimental devices, "low-nm" (which means tens of nm for the most advanced devices) has been done for a long time.

The low fabrication yields, which would be unacceptable for the mass production of integrated circuits, have much less relevance for small and expensive discrete devices and for experimental devices.
Show HN: Slice and Dice – analyze and explore User Prompts at scale
by acecreamu | 2025-07-24 14:54:57+00:00
Hi HN, we’ve recently sold our previous product and are currently building on new ideas. This one may be the most exciting and overlooked growth opportunity for AI products we’ve found:

TLDR: We’ve built a tool for analyzing and exploring user prompts — so you can actually understand how users are interacting with your AI product, and compare behavior across different segments (languages, paid vs free, etc).

If you’re used to Mixpanel / Amplitude / PostHog to analyze user behavior, you could notice how irrelevant they become when your product is just a chat box (or voice interface). That's because in the age of AI you don’t need button events — you need to analyze a large corpus of text.

To solve this, we’ve built what we call a Mixpanel for GenAI apps — an NLP tool to analyze and explore your user chats at scale.

We can already do:

1/ Multi-layer semantic clustering (see a big picture of all the topics and drill down)

2/ Filters and groups (compare usage between languages, demography, free/paid, etc)

3/ Latent space exploration

4/ Semantic search of prompts

5/ Topics and token usage breakdown

6/ (coming) Trends and audience drift over time

So you can answer questions such as:

- What’s the main use case of my app?

- What do users who pay the most do?

- What do users who spend the most time do?

- Which quiet audiences and use cases am I missing?

- How do the user patterns differ between languages?

- What are the new audiences we can appeal to?

Please check the link for the screenshots and instructions on how to start! Any feedback is appreciated (I don't say I won't cry if it's negative)

Worse - to manufacture usable boards, you need everything from the CPU socket and northbridge chip down to the dust-mote-sized discrete components that are mounted on it. Plus RAM, and ...

'Most all of which falls square into your "low tech and low profit", from a right-thinking* American company's PoV.

Not to say that a saintly American company could do much better, if it tried to swim uphill against America's vastly-higher cost of living (vs. the countries where most of that stuff's manufactured). And other problems beyond its control.

Try Arch Linux. It hits all your points except maybe 5.

1. It symlinks redundant bin and lib directories to /usr/bin, and its packages don't install anything to /usr/local.

2. You can keep most config files in /etc or $XDG_CONFIG_HOME. Occasionally software doesn't follow the standards, but that's hardly the distro's fault.

3. Arch is bleeding edge

4. Arch repos are pretty big, plus thete's the AUR, plus packaging software yourself from source or binaries is practically trivial.

5. Security is not the highest priority over usability. You can configure SELinux and the like, but they're not on by default. See https://wiki.archlinux.org/title/Security.

6. There are few defaults to adhear to on Arch. Users are expected to customize.

A good diet only helps so much. Of course with enough self control, a caloric deficit will make you lose weight, but you need to make yourself perpetually hungry. Eating clean without measuring and limiting portions is not enough for people whose appetite is naturally higher.

Ozempic was the only thing that actually solved my hunger. I would eat healthy, do exercise, but without ozempic my appetite was unstoppable and would think of food 24/7.

BTW you can still improve your diet. PB and bread are bad for weight loss. Go with high protein, low carb. But even that was not enough for me.

This is less a hybrid thing and more a new transmission thing. It, of course, isn't free. The efficiency of a CVT is a good 10-20 percent lower than previous transmissions. That said, currently, the win from keeping the engine at either the max power or the max efficiency speed is substantial.

There are some really good videos out there going over how newer CVTs work. Looks like some people are working on ones that are teeth driven, to reduce the loss from being free belt driven. Borderline magical stuff, all told. (Obviously, not magic magic. But very very impressive designs.)

Unsurprisingly, the title is sensationalist and not representative of the study. The study compares energy expenditure across different economic groups i.e. western people sitting in offices versus hunter-gatherers in Africa, and found that difference in energy expenditure does not account for differences in obesity, so points to consumption as the likely reason.

The sample dataset explicitly excluded 'athletes', so would exclude people that _are_ outrunning a bad diet. We know that a little weekly jog around the park doesn't mean you can eat a cheesecake every day, but anyone who has done extensive 'athletic' physical activity knows that if you don't up your calorie intake that you will lose weight. The study does not conclude, at all, that you cannot outrun a bad diet. Instead, it suggests "that dietary intake plays a far greater role than reduced energy expenditure in obesity related to economic development."

Edit: My point is specifically not about running. I am merely pointing out that if you read the study you will find that it is more of a study on economic development, and not really useful for personal or localised health advice. It observes that economically developed population groups may be more sedentary, but do not expend significantly more energy - so a hunter-gatherer picking berries all day does not burn significantly more energy than an office worker (at least not enough to explain why the office worker is obese). Therefore, the link between economic development and obesity is likely related to food (dietary intake) than daily activity.

SSE?

It makes sense for 2014 when AVX was not too widely deployed. Today you can double the throughput with AVX and probably get 4x improvement with AVX512.

GPU SIMD is also popular but perlin noise seems too 'small' a problem to be worth traversing PCIe over. But if you had a GPU shader that needed perlin noise as an input, I'd expect GPU to easily use this methodology.

It is worth revisiting how different techniques worked out over the last decade. Strangely enough, CUDA code from 2014 would likely be still workable today (perlin noise doesn't need the new GPU instructions of 4x4 Float16 or Raytracing).

OpenCL IMO is the wrong path though, which is what many would have picked from 2014 era for GPU.

I've been looking for a place to talk about this. Seemingly through a potent combination of government subsidies, willingness to embrace the technology, and general STEM competence, China has exploded with quality EV manufacturers. The ICE manufacturers are doomed regardless of what type of car they try to sell.

It makes me wonder about this from a policy perspective. China, more than any other country, has the power to dump products at a net loss to the country for the sake of a long term victory. That's tough to combat.

I can confirm the same from my messenger days. On days when deliveries were sparse, we found ourselves moving from cafe to bakery, eating more pastries than a doctor would recommend. Regardless of the day's activity levels we would generally drink large amounts of beer after work and sometimes during. Maintaining weight and satisfying our appetites was always a more pressing concern.

I'm not a dietician, but when I read things like this NPR report, I wonder how much of it is motivated reasoning. "It is not your fault", is always a good come-on for a sales pitch. This report seems like something people would like to hear, especially if they haven't come to enjoy strenuous exercise.

That said, I've always had a bias against highly processed foods.

I switched to NixOS to solve this sort of problem.

Configuration of system-wide things is done in the nix langauge in one place.

It also has the most packages of any distro.

And I found packaging to be more approachable than other distros, so if something isn't packaged you can do it properly rather than just curl|bash-ing.

You're trying to eat clean instead of lean/volumous. Why care about palm oil or salt in peanut butter if it's still like straight fat that you're passing on your bread every day? The actual diet move would be to switch that to some fruit and low fat yogurt. Same thing with whole grain bread, you just got some more fiber and vitamins but the calories are mostly all there still, especially if it's sandwich bread.

Clean/natural/unprocessed is an independent variable from fattening. There is correlation in that processed foods are sometimes highly palatable, but there is no causation. To illustrate, you could top your toast with either honey or Mrs Butterworth's Sugar Free syrup. Honey will add like 10x more calories, but is unprocessed, while the syrup is as processed as there can be

Funny, I had this need just today, but with a not-so-popular GitHub repo I cloned today. Before running it, I opened the folder in Cursor and requested a check for suspicious activities, which after a good scan of README and source files, Cursor reported back that it was ok to proceed.

I think getting an (optional?) AI heads-up before reviewing it myself would be great for cURL shell scripts as well. I'm prone to not seeing dark patterns in editor, and tools like vet could as well be tricked into not seeing the dark pattern, malicious intent, or just hazardous code lurking.
by saghm | 2025-07-24 14:57:52+00:00
That's fair, but I'd still argue that there's a difference in whether code has to be written by defining objects directly or being able to work at a different abstraction level where objects are an underlying implementation detail that get leveraged by other language constructs that are familiar from non-OO paradigms. Whether or not that difference is important or good is a subjective opinion, but I don't see an argument about the underlying implementation as a particularly strong refutation of someone stating that they like having that level of abstraction available.

Been in a weird position where I had to learn Java real fast, then learn Kotlin real fast to replace it. I find Java to be so incredibly unproductive compared to Kotlin, for all the reasons a sibling comment listed. I mean come on, default argument values and named input parameters are table stakes— it kills off the billion overloads, billion positional arguments, annd builder pattern nonsense all at once. Kotlin immutability by default is fantastic, I am 1000% behind default immutable data structures. The stupid, awful nullability madness disappears (mostly, need to train people to never use ! and !!). I appreciate Java, it got us to Kotlin, but Kotlin is ACTUALLY FUN to use, and expresses all ideas I have cleanly. Less, cleaner code just makes things easier to maintain, full stop.
by RamblingCTO | 2025-07-24 14:58:11+00:00
We did and it's awesome. Normal SaaS startup-sized codebase. Migrated from java maybe 4 years back. Was so perfect that you could migrate file by file. Later on we split up the codebase via gradle modules. Very very happy with that! Java will never get where kotlin is. It's a perpetual catch up game.

Everyone in bodybuilding or adjacent crowds already knows this.

How fat you are is entirely a function of how much you eat. If you want to put on weight, you bulk by eating more. If you want to lose weight, you cut with reduced calories.

The idea you could instead bulk by doing less cardio and cut by doing more sounds completely crazy. In reality, you do more exercise on a bulk because, duh, you can recover from more volume when eating a surplus.

There's a lot to discuss.

First off, a number of statements are nonsense. Take, for example

> you shouldn't be writing SIMD instructions directly unless you're writing a SIMD library or an optimizing compiler.

Why would writing an optimizing compiler qualify as territory for directly writing SIMD code, but anything else is off the table? That makes no sense at all.

Furthermore, I was writing a library. It's just embedded in my game engine.

> Instead you should reach for one of the many available libraries

This blanket statement is only true in a narrow set of circumstances. In my mind, it requires that you ship on multiple architectures and probably multiple compilers. If you have narrower constraints, it's extremely easy to write your own wrappers (like I did) and not take a dependency. A good trade IMO. Furthermore, someone's got to write the libraries, so doing it yourself as a learning exercise has value.

> There are loads of libraries like this [...] and provide targeting for a vast trove of SIMD options without hand-writing for every option.

The original commentor seems to be under the impression that using a SIMD library would somehow have produced a better result. The fact is, the library code is super fucking boring. I barely mentioned it in the article because it's basically just boilerplate an LLM could probably spit out, first try. The interesting part of the series is the observation that you can precompute a matrix of intermediates and look them up, instead of recomputing them in the hot loop, effectively trading memory bandwidth for less instructions. A good trade for this algorithm, which saturates the instruction pipelines.

The thing the original commentor does get right is the notion that thinking about data layout is important. But, that has nothing to do with the library you're using .. you just have to do it. They seem to be conflating the use of a library with the act of writing wide code, as if you can't do one without the other, which is obviously false.

> I was going to quickly rewrite the example in Highway ..

Right. I'll believe this when I see it.

I could pick it apart more, but.. I think you get my drift.

It irks me that the current administration points to the steel industry doing well as an example of bringing jobs back to the US. Like great you’ve made an uncompetitive industry more profitable at the expense of every downstream user of that material. Doing the very opposite of what should be done. We’re getting to the point, and have passed it in a few industries, where it’s more expensive to buy raw inputs in the US than refined outputs from China. That is a level of insanity that cannot last.
by klabb3 | 2025-07-24 14:58:22+00:00
Right, of course. But there's a difference in moral code on: who is the rightful owner of the surplus generated, and how should it be redistributed.

a) private ownership, even charity is directly immoral (Ayn Rand)

b) private ownership, no state redistribution but charity is morally compelled (religious conservatism)

c) private ownership, reluctantly accept state redistribution to prevent social- or system tragedy. (US republicans and democratic establishment)

Note that all of the above are what I'd call property rights fundamentalists. Then you have:

d) mixed ownership: surplus morally belongs both to you, and the system that allowed you to do business in the first place (US progressive liberals + most of the world's centrists)

Here's where the rest of the world generally reside. There's endless diversity and constant debate about the how, the who and the how much.

The problem with the US "left" is that it's split: the liberal progressives are in (d) but the establishment remain in (c): they're subconsciously conceding to property rights fundamentalism while advocating for redistribution, which puts them in a constant uphill battle to "immorally" extract value from the rightful deserving class of billionaires and business owners. That's also why democrats are considered right-wing by policy compared to the majority of the Western world.

Personally, I think this is why Bernie, Mamdani, AOC etc gets subject to such disproportionate attacks. Fiscal policy-wise they're pretty meh (just go back a few decades in the US and you'll find the same), plus their real-politik influence is also pretty mid. BUT, the real issue is they're shifting the moral baseline from (c) to (d), which is an extremely dangerous perspective shift for established interests. Rhetoric like "pay your fair share" is unacceptable to the hegemony.
