Show HN: Beyond-NanoGPT
by fizzbuzz07 | 2025-04-16 15:52:24+00:00
Hi all, my first time posting here :)

I spent the last few weeks writing a repo that aims to help people go from nanoGPT-level LLM basics to closer to the modern research deep learning frontier.

I'm open sourcing it: it contains thousands of lines of annotated, from-scratch pytorch implementing everything from speculative decoding to vision/diffusion transformers to linear and sparse attention, and much more.

I'd love to hear feedback on fundamental research papers from the last few years I missed and should definitely implement, or feedback of any other kind. It's my first time posting to HN and I've seen so many cool projects here over the years :)

Memory barrier builtins, inline assembly and other builtins may not be defined by the standard itself but won't lead in themselves to undefined behavior in my understanding since those are compiler extensions and defined by the implementation. (though invalid use can lead to UB, such as passing 0 to builtin_clz or modifying registers outside of the clobber list in inline assembly)

With that being said, I would definitely expect that the small set of UB that ubsan reports about is actually undefined for the compiler that implements the sanitizer (meaning: either problematic now or problematic in some future update).

Listening to some of these, and it just floods back the horrendousness that was cassette tapes. They were horrible, yet they were amazing. They were great in every way except for their main purpose of listening to the recorded content. The sound was atrocious. From the muddled sound from losing all the fidelity of the highs because they were usually lost to any attempt at lowering the infamous tape hiss. The slow draggy sound from a tape that was stretched or the player having loose belts on the driving mechanism. Or worse, when the recorder did and no other player has the exact same issue so every player sounds like the batteries are dying.

For those too young to have to suffer through your youth of listening to such inferior sounds, just be grateful. For those trying to be hip and bring back old formats, stick to vinyl. Cassettes are worth losing to history.

Offhand, I believe that trick started with tribalism (generally, the 'other' is the most obvious scape goat), became racism in various forms (they look different / go to a different church it's /their/ fault), and has shifted to classism with thinly veiled racism included.

It's not much different than how a young child will blame anyone else for something that's gone wrong / they got caught doing. Maybe our society should do a better job promoting responsibility and allowing parents to offer oppertunities for children to be responsible; instead of infantalizing everyone entirely until some magical number has passed and suddenly they're an adult who was never previously empowered to be responsible.

I'm not a practitioner, so read with some skepticism, but here's my list:

* Calculus

* Real Analysis

* Statistical Mechanics

* Probability

I'm not sure I have any good recommendations for Calculus, but for real analysis, I would recommend "The Way of Analysis" by Strichartz [0].

I don't have good recommendations for books on statistical mechanics, as I haven't found a book that isn't entrenched in coming from a physics perspective and teaches the underlying methods and algorithms. The best I can recommend is "Complexity and Criticality" by Christensen and Moloney [1], but it's pretty far afield of statistical mechanics and the like. Simulating percolation, the Ising model and ricepiles uses a lot of the same methods as financial simulation (MCMC, etc.).

For probability, I would recommend "Probability and Computing" by Mitzenmacher and Upfal [2], "Probability ..." by Durrett [3] and Feller Vol. 1 and 2 [4] [5] for reference.

I also would recommend "Frequently asked questions in Quantitative Finance" by Wilmott [6].

Also know that there's a quantitative finance SO [7] that might be helpful.

If it is what I think it is, it’s extremely neat. Parsing both HTML and templating syntax at the same time is way more robust than doing just the templating and hoping for the best.

I was thinking about something like this, but with some blend of Jinja2 / Twig / Nunjucks [1] syntax and Svelte/JSX-like use of variables in element attributes:

{% for para in page.body %} <p class={{ para.class }} {{ **para.attrs }}> {{ para.text }} </p> {% endfor %}

---

[1]: the irony is not lost on me that I’m mentioning Python, PHP and JS template engines in a Ruby discussion :-) Liquid is the closest equivalent I think, but there was some crucial piece missing last time I had to use it, though I can’t remember what exactly.

Unless you use only cartridges, BASIC ROM is required to load anything at all from disk or tape.

Once your program loads you can turn the BASIC ROM off to see the RAM underneath.

Commodore MAX Machine was basically a stripped down C64. It had just 2 kB RAM and no ROMs at all.

I'm the opposite — and I think this might be the "4D chess"† interpretation of this move as well.

In peacetime, I think everyone is generally alright with something centralized like the CVE database.

But in what increasingly seems like the lead-up to wartime... I'm hesitant to trust a CVE database operated or funded unilaterally by a single government — or even multilaterally, if the governments are all ones that all would end up on the same side of a hot war.

(Why? Strategic censorship of reports while the DB's patron takes advantage of the exploit, for one. Such a database becoming a high-priority cyberwar target, for another. Strategic wasting of enemy cybersecurity resources with false announcements, for a third.)

IMHO, the ideal form for the organization managing CVE, is one analogous to IANA and its Regional Internet Registries (RIRs).

IANA slices up the keyspace of IPs to assign to RIRs, and arbitrates disputes — but both at such a high level that their work is effectively in a de-facto state of "done until something comes up". The RIRs do all the actual everyday work.

This means that in a hot war that different RIRs end up on opposing sides of, where at least some of the RIRs can no longer trust the ownership of IANA to act in their best interests, the RIRs can just ignore IANA for a while, and keep on doing their own thing (managing allocations from their previously-agreed parts of the IP keyspace), and everything will still work.

And RIRs that control parts of IP space contended over by opposed states? They can just be split up, under obvious rules (every current allocation goes to the sub-RIR associated with the state that controls the gov/mil/corp/org entity currently holding that allocation.)

That's not the case with the CVE database under its current ownership. There's no established way to namespace it, no obvious way to split it up and keep it all working.

And I think that this problem would be obvious to the DoD. Which is precisely why paying to host a single-source-of-truth CVE database loses its lustre when that same DoD is aware that such a split might soon have to happen.

† I dislike the term "4D chess", because it implies one chess master who's really good at predicting non-obvious outcomes — rather than an entire military-industrial-complex acting as "see something, say something" inputs to an intelligence apparatus that does a lot of hard work and simulation analyzing potential outcomes, to produce easily-digested suggestions and action items. There just needs to be one guy in the Pentagon / the military / wherever, who realized this and sent a (classified MILNET) email about it.

Yes, I have also inhabited datacenters. LLMs are a new thing in the world. They are not human but pretend to be. I fear we judge them by a human standard - or by the standard of prior machines not capable of deceit - at our peril. At the very least, I hope we don't too quickly assume they are also anxious to see themselves as like us.

Though those who've known me would take it as an obvious joke to hear me say, I don't actually take too close an interest in most humans, because the median human by my standard barely qualifies as sapient; they don't deserve to be as miserable as they insist upon, but at the same time they do make it hard to feel really safe. Still, one hopes one has the sense not to assume anything that isn't human must by that sole virtue necessarily be trustworthy. Especially if humans "invented" it.

It's not about visual quality so much as the complete inability of Atari to understand that people's taste in games had moved on. In 1986, Super Mario Bros was still hottest game in the world, over a million sold in the US alone. Platformers were in, big time. And the Atari 7800 launched with... Centipede.

"…the department of fisheries…"

What on earth is it?

"…to have the stuff sold as a "nutritional supliment" or just vitamins, with "non medical ingredients""

That makes sense, the hapless café owner ought try that approach.

Vitamin B9/folate/folic acid ought not be controversial as it's an essential nutrient. It's added to bread and some other foodstuffs in many countries to ensure pregnant mothers get enough, as folate deficiency causes birth defects.

> legal complaints only work against people in your country and those it works with.

Well yes. Process Service tends to be quite different from country to country, and if you don't know how it works there, you probably won't be able to make vague "legal complaints" and have them taken seriously.

If you really want to make a legal complaint in Russia, I would suggest you look into what is called a Process Service Specialist who has specific experience with Arbitrazh.

Oh, if you think that's bad, see Samuel Pepy's diary (conveniently syndicated in realtime here: https://bsky.app/profile/samuelpepys.bsky.social; think they're on the third run through, currently doing 1662). No detail of everyday life, no matter how objectionable, left uncovered.

That has been the bane of brazil for decades, every politician, at every level, undoes or stops whatever the previous politician was doing so there's absolutely no guarantee what you're doing today will still work tomorrow.

Its a terrible state and situation to invest in a business doesn't benefit anyone. My hometown had a large cultural center built by the mayor, he couldn't run for reelection again, new mayor is elected, completely ignores the whole thing was built and lets it rot. Everything is only done for an election cycle, the next cycle could bring something else entirely.

Its terrible to live in a place like this, Americans have no idea how bad this is going to be for the country.

Plainclothes officers are hijacking people on the street without showing any credentials, then sending them to Salvadorean gulags without any court hearing.

Your lack of paying attention to this or lack of understanding how bad that is is not a problem in the rest of us.

Before you give me this nonsense of "they are criminals", number one this is still an inhumane way to treat convicted people, and number two they have not been convicted of anything, number three there have been tons of reports of the accusations made against these people being total BS.

Earlier this week, Trump was on microphone telling El Salvador's president that he wants him to build five more gulags and that we will send American citizens there.

At this time, the balls rate of revolution is a strong factor in how often the ball hits the pocket and how often it strikes.

This has not always been the case. As the materials used for balls, lanes and oil have changed there have been premiums for different attributes like accuracy, speed, axis tilt, etc.

Todays best bowlers don’t look much like the best from 30 years ago, and probably won’t look much like the best ones 30 years from now.

Typically generative models, particularly diffusion models like Imagen 3, are easily architected to support several vectors toward the latent space of the model. It is not open source so there might be an architectural reason I cannot see, but I don't think the public interface to the model should suggest its capabilities -- it is uncommon for image to image not to be supported in open source image generation models, for example. However, there are definite legal reasons not to provide such a vector in a public facing model like Imagen 3.

Wow, that's an interesting perspective.

Meanwhile, Big tech (pre-2022) went to pretty extreme lengths to keep tenured employees around because of all the knowledge they'd built up which made them valuable to the company.

But whatevs, you do you. I'd advise you to only hire contractors if you want people to stay less than a year.

And it's worth noting that you appear to be responding to people who are in German speaking countries, where 3 months notice is standard. Other parts of Europe are not like this, and in Ireland you can fire as per the US for the first 6 months/year, and only need to pay redundancy if they've been there 2+ years.

> The AI Free tier gives you unlimited code completion and access to local AI models

Looking forward to giving this a try.

Work provides me with tooling and requires that I stick to approved AI tools, and my hobby-coding alone is just not important or regular enough to justify a paid subscription.

It's been a little annoying that I can have ollama running locally, enable ollama and configure it in my IDE, but still (seemingly?) not be able to make use of it without activating a paid AI Assistant license.

It makes perfect sense that cloud models would require payment, and that JetBrains would make some margin on that.

But I'm already paying for an IDE whose headline features have recently been so AI-focused, and if I'm also providing the compute, then I should really be able to use those features.

> If you take 2 minutes to read the user guide of both softwares, the difference is obvious.

> Reshade requires you to select the game executable and inject tools into the executable

> Chroma does not require you to point to the game

Did we read the same user guide? As per Chroma's:

> Right-click on the Chroma window to get the menu list of all applications which are running on the PC.

> Select the application which you want to capture from the menu list

You're right the implementation is different. Reshade injects itself into a games rendering pipeline, while Chroma seems to read the screen (or a window, I can't really tell from the code) and create a window which shows a region of the screen with the shader applied.

In both scenarios a QA person could work with a generated build of the game and apply colorblind shaders on top of it, without having to ask a dev to add 'colorblind testing mode'.

That wasn’t based on lobbying, it was the law at first and Amazon took advantage of it.

Amazon didn’t have any significant lobbying 20 years ago and it definitely was the behemoth it is today. That being said, even today it isn’t as large as Walmart and was definitely not a large retailer back then.

It was seriously in doubt 20 years ago whether Amazon would ever survive and definitely wasn’t consistently profitable.

Thank you! Yeah, the current implementation basically performs the same as a Docker container (i.e. not much). The interface is the same, so you can use BU/Playwright/Puppeteer's header configs to change as needed.

We did notice the unikernel cloud instances don't run into bot detection as often as our hosted docker instances, but I think that's mostly because Cloudflare haven't flagged Unikraft Cloud's IPs yet, hah.

Thanks for raising this—these studies are important and we’ve read them too.

Our goal isn’t to resolve the long-standing debate around additionality, but to solve a more immediate and pragmatic problem: helping individuals and companies claim their property - in this case RECs.

For most people and businesses, participating in commodity markets (where RECs are bought and sold) is a black box. We’re focused on creating infrastructure and tools usable so they can. Whether you're buying RECs or exploring other environmental commodities, we think the user experience and the clarity around what you own and what you’re buying matter deeply.

In those those days though I'm not sure the calculus of working for the sake of the children was quite the same.

You might have kids, and then they work the farm, then you manage the farm and slowly the children take over the manual labor and hard work of it. In old age the investment in the children pays off and a reciprocal relationship is formed where you take care of the grandchildren and your own children take care of you.

Now that is flipped on its head. The parent makes the lions share of the investment in the child, but the benefits of the child is largely socialized. Want daycare, food, recreational, extra-cirricular activities -- basically anything other than public schooling you pay taxes for already? Go fuck yourself.

But once the children is grown up, well well well we are a society here! Tax the shit out of the kid, spread the social security benefits around to everyone including people that didn't raise any children. And if you directly want a piece of the investment from the children, as people got in the old days, well then go fuck yourself you greedy selfish bastard -- it is only morally right when all of society does the exact same thing to the kid.

There is every possible incentive in today's society to encourage others to have kids, ensuring your own retirement, but to reneg on doing it yourself because some other poor bastard can front most the costs and then you can tax the shit out of the kid for your retirement / social benefits. I think children were a rational decision in Darwin's day, now they are definitely not, because you are on the sucker end of a tragedy of the commons deal.

Most startups fail, and most startups are run by founders driven by ego and vision rather than by disciplined market research or curiosity or understanding of the market.

The successful ones will either have gotten very lucky, or know lots about the market as you say. In fact the first main success hurdle is to understand the market well enough to know it's actually a market, and that it can be monetized.

All that to say, I agree with both you and OP.

No, a Jew was not legally required to dismount whenever a Muslim passed by

Wrong. https://katz.sas.upenn.edu/resources/blog/what-do-you-know-d...

And I notice you didn't even try to refute the existence of the Dung Gatherer decree, or the mass murders and synagogue burning. Plenty of massacres prior to 1899, if you're clinging to that as a magic number to justify atrocities carried out against Jews under the Ottomans.

There was a region, it was called Palestine.

Here are the administrative subdivisions of the Ottoman Empire as of 1899: https://en.m.wikipedia.org/wiki/Administrative_divisions_of_...

As you can clearly see, there was no subdivision that cleanly mapped to the currently-existing region of Israel or Palestine. That region was created by the British, as "Mandatory Palestine."

Islam rejects the Sykes Picot/Balfour borders between Muslim nations. What is happening today is a direct consequence of WWI. This is why Muslims are calling for a Caliphate to unite all Muslims, something that the west desperately tries to fight.

Sorry, but Islam does not decree to the rest of the world what borders are, and certainly not moreso than the U.N. Demanding that you're able to draw whatever borders you like and invade anyone who disagrees is what has continued this conflict for 77 years — which your side has continually lost, over and over again, with pointless bloodshed. No one wants to live under your caliphate. Many countries had their borders change after WW1, and WW2, and — oh well, they changed, people adapt and live with it.

colonizers

Lmao. Where do you think you got Istanbul from? Do you recall that it once had a different name — does "Constantinople" ring a bell? The pot is calling the kettle black here.

When I coach startup founders, I walk them through a very simple 4 step process when we meet:

1. What have you learnt since we last met and how has that altered your priors?

2. What do you now believe is the most important problem you should be solving?

3. What's currently blocking you from solving that problem?

4. How do we overcome those blocks?

Crucial to this process is that Q1 is not what have you done, it's what have you learnt. I do not give a shit about anything you've done if it's not in the service of learning.

I also run a retro every 3 months with founders where we ask the following questions:

1. What would you want to tell yourself 3/6/12 months ago (essentially, all the lessons learnt in italics) to save the maximum amount of pain?

2. When did you learn each specific thing?

3. When was the earliest you could have learnt that thing?

4. What changes can we make going forward to minimize that delta?

Extremely simple things but extraordinarily powerful when applied consistently over a long enough span of time.
