For the battery life is your CPU scaling set to ondemand or performance? One can write an alias or function to switch from ondemand to performance for gaming then switch back to save power. One can also cap the max CPU frequency but that takes some experimentation to see what the lowest frequency usable with Zoom would be. When switching from Zoom to actually getting work done one can use an alias or function to switch back to max frequency options.

sudo cpupower frequency-info # or cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

Also take a look at powertop you will probably have to install this. One can set any devices they are not using to optimal settings. I avoid touching USB used by keyboard/mice and network interfaces I am using to minimize lag. Powertop can output to a file and that can be used in a startup script to automate the optimizations one has chosen.

There is also a sysctl setting called "vm.laptop_mode" which defaults to 0. On a laptop it can be set to 5 to combine writes and minimize storage wake-up. The caveat is that if the OS crashes one can lose up to 10 minutes of work. Most developers should avoid this setting unless their code editor autosaves frequently and syncs / flushes storage write caches. If unsure don't use it.

Another small gain is to ensure all daemons, desktop services and widgets not required are disabled or even removed. Some of them are power-hogs, some especially more than others. Powertop can sometimes expose this if left running for a while.

Another small gain can sometimes be installing "tlp" but different laptops and usage will see different amounts of power saving.

Oh and keeping the laptop off the lap can sometimes save power. More heat means more fan usage and thus more power usage. When at a dedicated desk using a laptop cooling stand multiple fans can extend battery life.

If one is feeling very adventurous they can install the latest bleeding edge kernel to net some small power savings but it may not be worth it if the laptop is used for anything critical.

I use a service where users can choose any frontier model, and OpenAI models haven't been the most used model for over half a year - it was sonnet until gemini 2.5 pro came out, recently.

Not sure whether you have your perspective because you're invested os much into OpenAI, however the general consensus is that gemini 2.5 pro is the top model at the moment, including all the AI reviews and OpenAI is barely mentioned when comparing models. O4 will be interesting, but currently? You are not using the best models. Best to read the room.

How sad. That wall map is a nice object and a good conversation piece to boot.

I guess you haven’t actually tried to buy a grandfather clock. Quality ones are in the thousands at least, if not tens of thousands. Even cheap ones are hundreds of dollars.

To my mind an apple watch is a fundamentally different product from a watch. They just both happen to be worn on the wrist.
A tokenizer that lets LLMs read 4x more (Demo inside)
by bramblestudio | 2025-04-12 12:25:07+00:00
I'm a solo developer working on semantic compression for LLMs.

I built a tokenizer that reduces up to 75% of token usage by extracting Subject-Verb-Object structures, adding contextual completion, and dropping redundant language.

Runs on CPU, no training required. Just clean, logical compression — results are stable, and it avoids hallucination. Great for boosting model throughput and reducing cost.

Tested on long academic paragraphs, averaging 4x token density gain for English text.

Live demo here: https://huggingface.co/spaces/Sibyl-V/BSE_demo

Looking to license or collaborate — ideally with people who can handle commercial execution, so I can keep focusing on core modules.

Any feedback welcome. Open to talk.

A few years back the US labeled China a “state manipulator” of currency.

Surely it will only take a few more rounds of pump and dumping the entire US economy for basically every country to label the US the same, and move away from US bonds and the US dollar as reserve currency. It just won’t be stable enough with all these antics.

When it happens I just hope trump won’t use it as justification for war.

Can someone explain why it isn't disingenuous to look at Euros?

Firstly, euros cost now as much as they did three years ago. So that is clearly a price that can be reached with any number of causes. Then, UK pounds cost only what they did last September. And other world currencies? Values vs the dollar are all over the map, up, down, and nearly unchanged. No clear trend at all.

I had heard a good way to check the absolute value of dollars is to google USDX. Guess what? It's not particularly low, well within the normal range of ups and downs.

I don't even see why "hackers" and "founders" should be related in any way. The hacker attitude (or approach to life) is that of curiosity and the need to build and create. The founder attitude AFAICT is how to get competent builders together and make money (on the positive end of the spectrum) or how to extract value from people instead of creating it (on the negative end of the spectrum).

I googled it and got "Hackers/Founders is a community of tech founders." I think that is sufficiently telling of what it's really about. It's another scam to "get those socially inept nerds to work for us and make us money without even realizing they are getting less than they deserve".

I’m still really surprised everyone loves Gemini 2.5 so much.

Even for coding I find GPT4o to be more concise and write more sensible things.

I get the one-shot ‘build me a flight simulator’ type thing is special to Gemini 2.5 - but who actually ever uses it that way?

I feel a bit old school for aging it, but I still prefer ChatGPT at this moment. Am I the only one?

I wonder if engineering close connections through structured vulnerability truly leads to meaningful relationships. The best friendships emerge organically through shared struggles and mutual support, rather than scripted conversations.

The idea of forcing deep conversations might neglect the natural dynamics that make friendships work.

Strong friendships aren’t just about emotional sharing—they also require shared responsibility, common interests, and personal development.

Friendship isn’t just a checklist of deep questions—it’s cultivated through shared experiences.

True friendships form through shared hardships, common pursuits, and a natural alignment of values. There’s something profoundly meaningful about forging relationships through mutual struggle, rather than intellectual exercises in vulnerability. If someone wants deeper friendships, they might be better served by pursuing meaningful challenges alongside others, rather than structuring conversations.

I like watches where I don’t have to change the battery. I have a kit to change them, but I appreciate the elegance of the purely mechanical solution, and my mechanical watches are generally my favorites for that reason. None of them are luxury goods or particularly expensive.

Even though I am not the kind of person who would spend an insane amount of money on a watch, I still think the elegance of the manufacturing of a piece like the one under discussion is really impressive and interesting.

Wouldn't fewer searches indicate better answers? A search engine is productivity software. Productivity software is worse when it requires more user interaction.

Also you don't need ads to answer what to do, just knowledge of the events. Even a poor ranking algorithm is better than "how much someone paid for me to say this" as the ranking. That is possibly the very worst possible ranking.

> this Vacheron-Constantin will likely be around 200 years from now

And why should I care? I won't be alive 50 years from now.

Besides, right now, what I care about is functionality. And, right now, my old Pebble offers far more of it than this jewelry for millionaires.

This thing is just a stupid Veblen Good[1], like a diamond ring, a Hugo Boss suit or a Porche Carrerra.

Remember, 150 years ago, millionaires used beaver fur top hats to show off. Have you seen any billionaire wearing them?

it wouldn’t surprise me at all if it were being manipulated, but we know for absolute certain facebooks sites and twitter are manipulated.

we should be looking to stop all manipulation, whether from a state or billionaires. this kind of manipulation is awful no matter what the source is.

I have yet to understand this obsession with agents.

Is making decisions the hardest thing in life for so many people? Or is this instead a desire to do away with human capital — to "automate" a workforce?

Regardless, here is this wild new technology (LLMs) that seems to have just fallen out of the sky; we're continuously finding out all the seemingly-formerly-unimaginable things you can do with it; but somehow the collective have already foreseen its ultimate role.

As though the people pushing the ARPANET into the public realm were so certain that it would become the Encyclopedia Galactica!

Hopefully the combined power of HN can figure out how to not enable this opt-in feature.

Feature toggles like this can be enabled on a single OS update, a single dial-home to the mother-ship. If the code is there I assume it is running. The only winning move is not to play.

So ... a bit off topic, but I want the opposite from OS vendors. The OS installation should take at most 3 minutes. Any features or geese that lay golden eggs that I desire should be a checkbox in a list of optional services. If I do not select anything the OS should not be bigger than 3GB for a desktop or 1GB for a server and even that is quite a bit bloated. If code is discovered on a machine that the administrator or owner did not intentionally install that needs to be treated as a security incident meaning "all hands on deck" and "all lawyers on a conference call with the OS vendor".

As a bit of a tangent, done right I should be able to click a button in Ansible and completely re-install the OS to a fleet of 100K bare metal servers in less than 10 minutes across 4 data-centers per region not counting POST time. Once the database OS is up their tamper-proof backups automatically restore, app servers grab their code and in 30 minutes every data-center is up and running. The first people in should be the customers and they might ask if we had a network blip.

That comment was for CISA. Make the above step 1 in chaos monkey tests for all corporations and governments and make live testing required by law to be publicly traded. This testing must be performed annually in a staging environment in every data-center to remain listed on the stock market or remain funded in government budgets. If code exists on a machine that need not be there it's a security incident. Let's not have another Sony/Tri-Star.

I like to believe that 16 years of Merkel left people with the inability of understanding politics and democracy in general.

Handling AfD by inviting them to a talk show where the audience/presenters were mostly people with Greens/Left background is emblematic of how this country has been delegating the ability to think democratically to someone else. No wonder we have extreme parties on the rise. (Both Left and AfD are extremes, no matter what)

Instead of listening, they made fun or criticized a party of monkeys that should have never reached 22%. Because that's all they could do. Make fun, minimize, claiming you're racist, etc.

Burning Tesla factories, breaking their cars while they are parked, ... letting protesters glue themselves on the streets blocking you from reaching whichever place you planned to (be it an office or a hospital). This is daily life in Germany in the last 3-4 years. Wtf!

I am personally sad that all the good things will change because the last 20 years I think Germany really became a great country, unlike all the criticism that people like to throw at it. All just because people couldn't confront the facts. And yes, this means making hard decisions where needed.

Several people have suggested that LLMs might end up ad-supported. I'll point out that "ad supported" might be incredibly subtle/insidious when applied to LLMs:

An LLM-based "adsense" could:

1. Maintain a list of sponsors looking to buy ads 2. Maintain a profile of users/ad targets 3. Monitor all inputs/outputs 4. Insert "recommendations" (ads) smoothly/imperceptibly in the course of normal conversation

No one would ever need to/be able to know if the output:

"In order to increase hip flexibility, you might consider taking up yoga."

Was generated because it might lead to the question:

"What kind of yoga equipment could I use for that?"

Which could then lead to the output:

"You might want to get a yoga mat and foam blocks. I can describe some of the best moves for hips, or make some recommendations for foam blocks you need to do those moves?"

The above is ham-handed compared to what an LLM could do.

>For any given thing or category of thing, a tiny minority of the human population will be enthusiasts of that thing, but those enthusiasts will have an outsize effect in determining everyone else's taste for that thing.

I think that's a self-dellusion many tech enthusiasts have, that they're somehow trend-setters.

And then the same enthusiasts say for the original iPod "No wireless. Less space than a Nomad. Lame", and see the masses jump to buy it, and themselves only catch up later.

Or they see the masses never caring for their e.g. desktop Linux, whose mass dominance (not mere "works for me" or "have set it up for my elderly parents and they don't even know it's not Windows") would come "any day now" for the last 30 years...

Trend-setters exist, but they're a different group than the "tiny minority" of enthusiasts. More like some musician paid to spot Beats headphones, or some cool dude sporting some gadget early on.

>For example, very few people have any real interest in driving a car at 200 MPH, but Ferraris, Lamborghinis and Porsches are widely understood as desirable cars, because the people who are into cars like those marques.

A hell of a lot of people had a real interest in driving a car at 200 MPH, if they could have the chance. And even more admired Ferraris, Lamborghinis and Porsches because of their design and elegance (and price, people aspire to luxury goods, even when they can't afford them), not because some sport-car afficionados said so.

It's the same in other areas: the popular books, or comics, or movies, or music, etc. are rarely if ever what the "inner" crowd of each niche admires. Most people buy Reacher and such, not Finnegan's Wake.

>So if you develop your product by following your analytics, you'll inevitably converge on something that just shoves content into the faces of an indiscriminating userbase, because that's what the median user of any given service wants.

More likely, if you want to keep and continue increasing your margins, and your stock price, you'll incrementally continue to shit all over your product trying to squeeze ever more money.

Neither the "enthusiasts"/tech-savvy users NOR the "median user" wants Netflix to be the shit it has become, or Google search to be so fucked up, or ads and nags on Windows UI, and so on.

They're just given those, and they accept them having no recourse. The moment there's a better recourse, they jump to it (like IE -> Firefox -> Chrome, or BS early search engines -> Altavista -> Google).
Show HN: AI wrote the python code. pyhunt tells you what it really does.
by easy_dev | 2025-04-12 12:36:32+00:00
As we enter the age of AI-assisted coding, we now spend significantly more time analyzing and reviewing generated code rather than writing it ourselves.

In particular, understanding where and how functions are being called requires considerable effort, and it's become common for the overall structure of code to change drastically during debugging or refactoring.

As the size of a project grows, the time required for such tasks increases exponentially. To address the increasingly complex and tedious debugging process, I developed a tree-visualized logging tool called pyhunt.

pyhunt visualizes the structure of newly defined functions and the lines where errors occur during code execution in an intuitive tree format directly in the terminal. This allows developers to grasp the code flow quickly and significantly reduce debugging time.

Never proposed a ban, the issue is copyright, use licensed inputs and I could care less.

Pro AI people need to stop behaving like it’s a foregone conclusion that anything they do is right and protected from criticism because, as was pointed out, the legality of what is being done with unlicensed inputs, which is the majority of inputs, is still up for debate.

I’m just calling attention to the double standard being applied in who is allowed to have an opinion on what the legal outcome should be prior to that verdict. Temporal said people shouldn’t “pretend or assume” that lots of AI infringes on other people’s work because the law hasn’t caught up but the same argument applies equally to them (AI proponents) and they have already made up their mind, independent of any legal authority, that using unlicensed inputs is legal.

The difference in our opinions is that if I’m wrong, no harm done, if they’re wrong, lots of harm has already been done.

I’m trying to have a nuanced conversation but this has devolved into some pro/anti AI, all or nothing thing. If you still think I want to ban AI after this wall of text I don’t know what to tell you dude. If I’ve been unclear it’s not for lack of trying.

Which can be said for most of the survivorship-biased "greats" we talk about. Right time, right place.

(Although to be fair — and we can think of the Two Steves, or Bill and Paul — there are often a number of people at the right time and right place — so somehow the few we still talk about knew to take advantage of that right time and right place.)

> There’s a reason James Bond wears expensive watches and that reason is product placement.

Only since Goldeneye when Omega started paying for product placement. Bond had worn Rolex since the original novels, which were written before their big pivot to luxury, so him wearing expensive Rolexes in later films was more of a historical accident. Rolex never actually paid a cent to appear on screen.

> Native apps also are suspended. Or can be, like na iOS (not being fanboy, I appreciate this mechanism).

On iOS web apps get suspended very aggressively, and there is no way for a web app to signal to the browser to not suspend it. I never developed native mobile apps, but I assume it’s less aggressive for native apps and/or native apps have a way to prevent themselves from being suspended. This doesn’t seem to be an issue on desktop though.

Acid's a solved problem; PTFE (Teflon) is a comprehensive solution to hot sulfuric acid, well validated in chemical engineering problems on Earth. It's versatile enough you can even coat balloons with it [0].

The hard part is keeping electronics cool. The balloon ideas offer a really elegant solution. You could cycle a balloon between altitudes—between the 500 °C surface, and cold layers of the high atmosphere, cooling off and refilling a thermal storage reservoir for the surface. On Venus, can find cool 20 °C air at a very reasonable, balloon-navigable, 0.5 bar pressure level [1].

This overgeneralizes IMHO. While the pain of being laid off due to something other than your own actions is fine, there are certainly folks out there who cause a lot of pain to others and aren't worthy of universal sympathy when their own pain comes along.

How would a final court ruling shield someone from executive power? The court relies on the executive to enforce its decisions. They can find a person in contempt, and order fines or jail time until that person complies, but I believe the orders are then enforced by U.S. Marshals, who are executive appointees.

This is a serious question. What have I missed?

There are lots of ways that advertising could be tied to personal interests gleaned by having access to someone's ChatBot history. You wouldn't necessarily need to integrate advertisements into the ChatBot itself - just use it as a data gathering mechanism to learn more about the user so that you can sell that data and/or use it to serve targetted advertisements elsewhere.

I think a big commercial opportunity for ChatBots (as was originally intended for Siri, when Apple acquired it from SRI) is business referral fees - people ask for restaurant, hotel etc recommendations and/or bookings and providers pay for business generated this way.

If we don't have due process, in that, you can't go and defend yourself in public court, nobody here is really legal or not. It doesn't matter if your birth certificate is in the other room. Without due process it's whatever the ICE agent that's bagging you feels like. What are you gonna do? You don't get due process, you get no court hearing, you get the pleasure of getting onto a plane and flown out to a slave labor prison in El Salvador. Also Garcia had full legal permission to be here but it shows they never checked it and thus he was whisked away like we can expect other's to be if things stay on the current path.

the way this is stated is troubling in that it proposes an aysimetric idea of "close friend" which is just one more version of hiarchical structure in human society, rather than something based on seeing things from the same perspective and the trust and understanding that comes.....after that discovery ie: "intentionlly making", vs finding I would suggest that the quality of the people that inhabit the mutual appreciation societys that pass as friendships amongst the "popular" extroverts is the impetus behind this sort of blind quest, the unrecorded and hard to imagine blank realisation of the inevitable "stalemates" in there social jockeing, no one there, vulnerable, to anything at all....how dry and tedious, that must be
