Show HN: Chisel – Profile GPU Kernels Without a GPU (Nvidia and AMD)
by technoabsurdist | 2025-06-26 20:55:17+00:00
We built Chisel to make GPU kernel profiling hardware-free. It lets you run chisel profile kernel.cu and get full Nsight/Ncompute or rocprofv3 reports without a GPU needed.

It spins up remote H100, L40S, or MI300X machines (via DigitalOcean for now, but gonna expand backends soon), runs your code, and gives you back detailed traces (kernel timings, memory transfers, API calls, etc). Everything is CLI-based and designed for iterative dev—profiling takes \~1–2 minutes per run.

For example:

# Profile a PyTorch training script on H100 with Nsight Systems chisel profile --nsys train.py

# Profile a HIP kernel on MI300X with system trace chisel profile --rocprofv3="--sys-trace" matrix_add.cpp

Repo: https://github.com/Herdora/chisel PyPI: pip install chisel-cli

Would love feedback! especially from anyone building custom kernels, ML layers, or low-level GPU ops.

I had a friend who had panic attacks and I say had because his approach to life led us to not being able to be friends anymore.

My take on his situation was that trying to eliminate triggers destroyed his life because he spent all his effort on avoiding triggers and wasn’t doing anything at all. The more he avoided triggers the more sensitive and easy to trigger he got. This isn’t just my observation, see the relationship between panic and

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

I think there are some people with a little anxiety who might benefit from some automated CBT but panic disorder is a serious condition that I think needs professional help, hard as it can be to get.

I don't know man?

Gonna have to disagree there. A lot of models are being used to reallocate cognitive burden.

A phd level biologist with access to the models we can envision in the future will probably be exponentially more valuable than entire bio startups are today. This is because s/he will be using the model to reallocate cognitive burden.

At the same time, I'm not naive. I know that there will be many, many non phd level biologist wannabes that attempt to use models to remove entirely cognitive burden. But what they will discover is that they are unable to hold a candle to the domain expert reallocating cognitive burden.

Models don't cause cognitive decline. They make cognitive labor exponentially more valuable than it is today. With the problem being that it creates an even more extreme "winner take all" economic environment that a growing population has to live in. What happens when a startup really only needs a few business types and a small team of domain experts? Today, a successful startup might be hundreds of jobs. What happens when it's just a couple dozen? Or not even a dozen? (Other than the founders and investors capturing even more wealth than they do presently.)

The effect has long been known, but it's pretty modest. Here's the data sheet for a typical modern solar panel:

https://static.trinasolar.com/sites/default/files/Datasheet_...

It loses about 0.29% of (relative) power output for every degree Celsius of temperature increase. If the module is operating at its maximum rated temperature of 85 degrees C, it's still about 83% as efficient as it would be under standard test conditions (25 degrees C).

Solar farms in sunny, hot regions generate more energy per year than identical installations in cooler, less sunny regions. The benefit of extra light dominates over the efficiency loss from higher temperatures. A location with as much sunlight as Las Vegas but the temperatures of Anchorage would be ideal, but there are few if any locations with those characteristics. That's why Las Vegas is still a good location for solar farms despite the heat.

This explanation gets repeated over and over again in discussions about the speed of the Rust compiler, but apart from rare pathological cases, the majority of time in a release build is not spent doing compile-time checks, but in LLVM. Rust has zero-cost abstractions, but the zero-cost refers to runtime, sadly there's a lot of junk generated at compile-time that LLVM has to work to remove. Which is does, very well, but at cost of slower compilation.

For example:

>What happens to people's monthly premiums when a US health insurance company's AI finds a correlation between high asthma rates and home addresses in a certain Memphis zip code? In the tradition of skull-measuring eugenicists, AI provides a way to naturalize and reinforce existing social hierarchies, and automates their reproduction.

This sentence is about how AI may be able to more effectively apply the current values of society as opposed to the author's own values. It also fails to recognize that for things like insurance there are incentives to reduce bias to avoid mispricing policies.

>The logical answer is that they want an excuse to fire workers, and don't care about the quality of work being done.

This sentence shows that the author perceives that AI may harm workers. Harming workers appears to be against her values.

>This doesn't inescapably lead to a technological totalitarianism. But adopting these systems clearly hands a lot of power to whoever builds, controls, and maintains them. For the most part, that means handing power to a handful of tech oligarchs. To at least some degree, this represents a seizure of the 'means of production' from public sector workers, as well as a reduction in democratic oversight. >Lastly, it may come as no surprise that so far, AI systems have found their best product-market fit in police and military applications, where short-circuiting people's critical thinking and decision-making processes is incredibly useful, at least for those who want to turn people into unhesitatingly brutal and lethal instruments of authority.

These sentences shows that the author values people being able to break the law.

Whenever a new tech (or cultural phenomenon) appears, you have naysayers such as this one.

Luddites fought against automatic weaving stools - by destroying the machines. Reasoning: It is stealing our jobs.

Comics were sure to destroy our children's minds, because they wouldn't read real literature anymore (conveniently forgetting that only 100 years before that, reading was considered a plague of the youth and putting their minds into bad places).

Rock music is of the devil. If you play "Stairway to heaven" backwards, and squint your ears just right ...

Phones that memorise phone numbers? Surely it is brain rot if you are no longer forced to memorise phone numbers.

Social media? Work of the devil! Manipulates the minds, causes addiction, bad elections, and warts on the nose!

Cryptocurrency? Waste of energy, won't someone please think of the environment? Only used for crime!

3D printing? What if someone ghasp prints himself a gun?

And now it is AI. And when AI is normalised, and something new shows up, it will be that.

Well that's kinda my point. If you are losing it, push back. I'm betting there are others who feel the same but also feel alone.

Remember, they hire us for our skills. They hire us for our expertise. That means not always being a yes man. If you don't stand up for what you think is right, the product will become worse. The reason to question your boss is because you're on the same side: making the best product you can. It's okay to be wrong, it's okay to speak up, it is okay to ask questions. If anyone says anything different, they aren't interested in making the product, they are interested in their paycheck. Frankly, most of this loss we're talking about is because the business people took over and don't understand that an engineer saying "but what about <x>" is not "no" it is "yes, but let's figure out how". This culture needs to be fixed, and it requires every day normal people to make that normal.

In a way; water mills and spinning jennies led to the dickensian horrors of the textile mills: https://www.hartfordstage.org/stagenotes/acc15/child-labor

The industrialisation itself, although increased material output, decimated the lives and spirits of those who worked in factories.

And the printing press led to the Reformation and the thirty years war, one of the most devastating wars ever.

I guess I mean in the sense of if you have the drones starting position, the end location (or approximate) and movement tracking based on terrain movement, like the cheap version of Tomahawk but instead of having a map you just use relative change from a stereo camera/lidar pointed at the ground to track relative movement? I guess the hardware to run that isn't available in mass production.

Us Americans have approximately zero to do with your rules or society. The idea of thinking Apple (or Microsoft, or Google) represents "Americans" is absurd. We don't vote for them to exist, we have no mechanism to stop their existence or oppose them in any way. We're as happy about EU forcing them to change as anyone else - our own attempts all failed. Jail break providers(for instance) were persecuted with legal process, gag orders, and seizure of their assets. Repairing iPhones as a side business? They put a stop to us doing that also.

I'm all in agreement with your emotional sentiment, but please understand "Americans" do /not/ like the same things you do not like. Our country just takes away our ability to do anything about it. Land of the free and whatnot...

> That's an arbitrary and irrelevant difference. Proof: if a future society upgraded human brains to have the same power as AI, would you then consider it to be immoral and illegal for humans to witness the works and creations of others?

I would hope if we all had brains powered by AI we would recognize how stupid the game we're playing is and end it already, do away with the notion of money as a whole, and just set about living good lives, since that's what AI itself largely suggests we do. However, if this extremely tenuous metaphor is be executed as is presented, if indeed a human could look at a Rembrandt, and subseqently produce 9 copies of it per minute, no, viewing it shouldn't be illegal, but selling the copies absolutely should and would be.

Like if you just want to obsessively generate AI art and... idk, staple it to your wall? That's not illegal, nor even unethical. You don't need to generate it either, you can just print things, and have them.

> Or take the inverse: it's illegal to use a copy machine to mass copy and distribute somebody else's work, but should it be legal for a human to do this by hand, since humans are massively slower than a copy machine? No, it shouldn't, both should be illegal.

No shit.

It all was at the expense of environment.

And if we define being good as “help us to further keep human race alive as top spiecies”

Then yes, technology caused more harm than good.

World is currently experiencing another mass extinction event and at the current pace of events billions of ppl will either die from starvation or dehydration or various ecological disasters or wars caused by population migrations.

To me it's self-evident, but is probably one casual step removed from what you'd like to see. I can't point to specific finished or released projects that were substantially accelerated by use of GenAI[0]. But I can point out that nearly everyone I talked with in the last year, that does any kind of white-collar job, is either afraid of LLMs, actively using LLMs at work and finding them very useful, or both.

It's not possible for this level of impact at the bottom to make no change on the net near the top, so I propose that effects may be delayed and not immediately apparent. LLMs are still a new thing in business timelines.

TL;DR: just wait a bit more.

One thing I can hint at, but can't go into details, is that I personally know of at least one enterprise-grade project whose roadmap and scoping - and therefore, funding - is critically dependent on AI speeding up significant amount of development and devops tasks by at least 2-3x; that aspect is understood by both developers, managers, customers and investors, and not disputed.

So, again: just wait a little longer.

The biggest quarrel I have with it is that even if you get clinically tested, at least in the cases where I asked friends who got tested, they did not even try to rule out other causes, like repressed childhood trauma/cPTSD. People might end up on potentially lifelong medication, where other treatment options and recovery may be available.

How about a binary - either you subscribe to Gemini or you don't. Rate limits or gates for higher tier models/capabilities, that you can upgrade to unlock. Think Small/Medium/Large. Anything more complicated than this is immensely annoying to both consumers and enterprise customers. For power users/nonconformists, include a pay as you go option using credits or cost per action that has access to all capabilities out of the box.

Ok, in over a decade on HN I've never commented on a product but this one is awesome! I just signed up!

I currently pay $99 a month to learn Spanish from a live tutor 30 mins a day, and this is far superior if you ask me.

The element that stands out to me is that the AI Tutor is consistent and concise!

They're accounting identities, not casual relationships. Exports are stuff that's part of domestic product (but not consumed domestically) so get added. Imports are stuff domestic consumers get the benefit of but aren't actually produced domestically, hence the direction of the signs in the accounting identity. The 4:3 ratio is consistent with an economy which might be more open than a 3:2 one, but it doesn't actually have a higher GDP unless there's higher consumption or investment or government spending as a result of the extra trade.

The key part is that nobody should care about any values or ratios in isolation or impute causality that isn't there. Otherwise people start believing that doing crazy stuff to shrink a trade deficit results in higher GDP, as opposed to lower C+I+G. And when those people are sufficiently stubborn and sufficiently powerful, you get $economy shrank 0.5% in the first quarter headlines...

All those LLMs are trained on stolen data, is pushed by ultra capitalist tech bro and billionaires, and eliminating jobs in creative industries.

It’s heralded as a tool for increasing efficiency (a western capitalism favorite euphemism for cancerous exploitation of the environment and humans) while neglecting it’s externalities, which includes destroying the jobs of the very people it stole the work from, and making you more reliant upon it, possibly to the point you forget how to do the things you use it for.

It’s a pretty devilish poisoned fruit.

Wow, thank you, that is very kind.

Something my wife and I decided very on in our journey into the space was to be as open as possible about it; both to help with distigmatjzation as well as just general knowledge sharing. I certainly knew nothing about mental health and illness until severe mental illness arrived on our doorstep and we had to get educated fast.

With 5% of the US population suffering from severe mental illness and another 20% having experienced an acute or less significant issue, it is quite common. The more we know, the more we can be helpful to those around us or ourselves.

I gave a 'co-learning' presentation on mental health to our company... maybe I should consider expanding the scope of my shared experience. Thanks for your encouragement.

What would you say the delta is between Element's current video-rooms and Discord-style voice-rooms (if you go and mute video for everyone), ooi? The only reason Element hasn't implemented precisely the same UI as Discord is because it's not (currently) trying to be a Discord competitor, but more a "run your own encrypted Teams alternative", given that's what Element customers are asking for right now, and we're having to follow the money to try to get sustainable. However, what we're trying to do is to ensure that Discordish features still work, despite having to focus more on Teamsish features.

In terms of permissions: I'm a bit surprised that folks feel limited by Matrix's freeform hierarchy of permissions. Every user can have a 'power level' from 0 to 100, and you can then customise the threshold required for literally permission (e.g. you need power level 54 or higher to kick users, or whatever). The only difference with Discord is that Discord lets you pick entirely arbitrary combinations of permissions (e.g. have one user able to kick but not ban, but another user able to ban but not kick, or whatever). How useful really is this in real life usage though?

I'm trying to work out whether the problem is if Element's UI for configuring permissions is too basic, or whether folks really do need a full RBAC permission matrix, and if so, for what use case?

> Its a matter of years until it can completely replace humans in any form of intellectual work.

This is sensationalism. There’s no evidence in favor of it. LLMs are useful in small, specific contexts with many guardrails and heavy supervision. Without human-generated prior art for that context they’re effectively useless. There’s no reason to believe that the current technical path will lead to much better than this.

> FreeBSD also needs an OS-level graphics/window API just like Windows. Linux is still trying to pretend like its the 60s where text was the only way to interact with a computer.

You have no idea what you're talking about. Linux has DRM and Mesa. You can do hardware accelerated rendering in a TTY with next to no dependencies if you feel the need for whatever reason.

Unless your objection is the lack of a "blessed" display server or GUI toolkit or something? But I don't think anyone wants that sort of monoculture. Perhaps the systemd folks will take you up on it if you file a feature request?
by mrcwinn | 2025-06-26 21:00:54+00:00
Yes, before AI, society was doing fantastically well on "social relations, empathy, and care." XD

I remain an optimist. I believe AI can actually give us more time to care for people, because the computers will be able to do more themselves and between each other. Unproven thesis, but so is the case laid out in this article.
by reval | 2025-06-26 21:01:18+00:00
The counter-counter-argument is that the messy part of human interaction is necessary for social cohesion. I’ve already witnessed this erosion prior to LLMs in the rise of SMS over phone calls (personal) and automated menu systems for customer service (institutional).

It is sad to me that the skill required to navigate everyday life are being delegated to technology. Pretty soon it won’t matter what you think or feel about your neighbors because you will only ever know their tech-mediated facade.

Kinda? https://en.wikipedia.org/wiki/Luddite

> The Luddite movement began in Nottingham, England, and spread to the North West and Yorkshire between 1811 and 1816.[4] Mill and factory owners took to shooting protesters and eventually the movement was suppressed by legal and military force, which included execution and penal transportation of accused and convicted Luddites.

I hope someone is keeping a list of all these crazy rollbacks so the next democrat administration (assuming there is one dun-dun-dun etc) can be held accountable for not rolling back the rollbacks.

Even if they do I'm worried that this kind of sabotage of progress will become the new norm, with each subsequent administration undoing everything the previous one did as standard, and going even further to appease the extremists.

I know this has always happened to some degree with executive orders (the was a great tradition of presidents signing all sorts of crazy stuff just so the next guy would have to undo it and look bad) but it seems nuclear now (sometimes literally)

I can't say I agree with that take:

>...have willingly ceded agency and sovereignty to a handful of unelected Capitalists who convinced us that this invention will somehow, finally, inevitably solve all our ills and enable a utopia.

I've been around for that half century. The system of government is much the same. The new tech like pcs, mobile and the web are mostly tech gizmos that people quite like and choose to buy, not some fiendish plan sold as utopia.

One issue with tools like these is that it's pretty artificial. You rarely need to type nonsense series of lowercase only words without punctuation at a consistent character speed.

I did a similar little tool at some point where I just used some books from the gutenberg project and normalised it a bit so there were no weird typographic quotes etc.

It both forces me to become good at the punctuation, and it's more interesting as I will accidentally start reading that book.

The article buries at the end that it’s present in only 5% of all the vaccines including the multi-dose flu vaccines (aka a bulk bottle that would be used to dose a large number of people, more cost effective than smaller doses that don’t need as many preservatives) and that the biggest concern is that they’re disputing “settled science” (on a preservative that was removed from the majority of child and adult vaccines for what the article attempts to portray as unnecessary safety/precaution back in the early 2000s) that other countries rely on, and that if the global perception of the ethylmercury preservative shifts toward negative, it will mean more countries will use vaccines with less preservatives which could make them more expensive or harder to get.

As an independent developer, I wish the EU would reverse their decision to make me either doxx myself or not have paid apps in the EU App Store. Thankfully, right now my only app is free so I can get away with saying that I'm not a trader.

I'll probably just have to bite the bullet and form an LLC with a rented address and phone number once I get ready to release a paid app, which unfortunately just increases my costs even more for what is most likely to remain just a small side hustle.

I still don't see a good reason why independent developers like me should have to publish their personal address and phone number on the App Store. I'm not willing to put my family in danger like that.
