Show HN: Quizwhiz.ai: Generate Quizzes and Notes and Self-Assess
Hi guys,

I launched this website about 2 years ago. It is meant to help teachers generate exams and quizzes for their students and for students to self-study.

Key Features:

1. Quiz Generation:
- Multiple question types: MCQs, short answers, fill-in-the-blanks, true/false
- Interactive diagram labeling tools
- Download Quiz for save for later user

2. Study Note Creation:
- AI-generated notes from various inputs and topics
- Option to choose pre-generated notes based on curriculum standards

3. Self-Assessment:
- Adaptive quizzes that adjust difficulty based on performance
- Helps students self-assess based on the quizzes they create

4. AI Chat (RAG): Chat with your notes.

I'd really like some feedback.

Thank you!

Does the book contain an apology for perpetrating the hoax? If not I’m not particularly interested.

The Stanford Prison Experiment is the kind of thing that gives the entire field of psychology a bad reputation. It’s literally used as a case study in how not to design experiments.
It is allowed. I did exactly that for my apps.
The way that I've seen GP's point expressed that makes sense to me is that the per-person cost to provide health-care for those special interests you mention is roughly equivalent to the per-person tax burden in most other developed countries to care for everyone. That gives me a useful handle on how gob-smackingly wasteful the US system (writ large) actually is.

Yes, but we should also be honest about the fact that this protectionism will have a cost. In the case of farm equipment, it means that everyone who buys food will be paying more to subsidize the protected industry.

I'm not making a judgment on whether it's worth it or not, I think that depends on a lot of details, but when people throw out tariffs they are rarely honest about the fact that it's a tax that flows downstream to the end user. In some cases multiple ways, like farmers who pay higher cost for equipment due to tariffs, so production of their soybeans (or whatever) are higher, so then they needs USDA subsidies to make them price competitive for export, so there's multiple layers of taxation there to make it work.
Well my impression form first hand experience with Worldcoin is they are biased.
It's more of a LaTeX alternative, which also happens to have an official web app.

The engine itself is open source, so you can always just install it and compile your documents on the command line.

This is one highly confusing sentence. Nothing motivates who? Saudis? Arabs or Muslims generally? Or do you mean Brown people?
"the knocker-up soon found out that while he knocked up one who paid him, he knocked up several on each side who did not" -- I thought it was the employer who paid the knockers!

This has affected me my whole life. It doesn't matter which bookstore or the type of books it specializes in as long as I'm interested. My earliest memories of this phenomena are at comic shops as a kid. I noticed it in record stores in my 20s too. For me it's the anticipation of finding something new and the fear of missing it.
Disagree. The scientific method is an attempt at ascertaining the truth. It makes sense to extract a technical definition of what this process is devoid of human factors like “explanation”.

Similar to formalization where we determine the grammatical rules of a language in linguistics or formalization of a physical system to develop models for by using the statistical definition of hypothesis I am doing the same technical extraction here.

Sure informal definitions of hypothesis are useful but formal models are also useful and thus a formal model of science as defined by statistics is useful as well.

I am not denying alternative definition of hypothesis.

I am just saying that for the rigorous categorization of the term “theoretical computer science” we find that it doesn’t fit into the rigorous definition of the scientific method. There is a clear delineation here. If you want to use other definitions where “usefulness” and “explanations” are a factor then what literally stops knitting from being a science? Knitting can be useful and technical in terms composing fabric together…. why isn’t it a science?

You see the issue here and why technicality or formalization is needed? Intuitively we know knitting isn’t a science but we aren’t sure technically why… The technical definition of science elucidates the reason why knitting is not a science… because knitting doesn’t involve hypothesis testing. Plain and simple. We discard fuzzy terms like “usefulness” and it ultimately becomes clear why knitting isn’t a science.

The other reason why the statistical definition of hypothesis is useful is because it helps us delineate categories for terms where our intuition fails and becomes ambiguous. We aren’t sure where “theoretical computer science” fits into terms of science or mathematics. Using technical definitions we find that theoretical computer science is actually a math and not a science.

If we use informal definitions then nobody is sure what computer science is. The mind is confused thinking it’s both a science and a math at the same time and the op starts to use analogies in attempt to justify certain categorizations. Any time you use analogies as proof you hit a sort of failure because analogies don’t prove anything. You need to use definitions as proof.

Hence the need for formal definition's. Your philosophers definition of hypothesis is unfortunately too informal.
Ask HN: Not Acceptable (openresty) – How to debug
I use AdGuard’s Adblocker on the client along with NextDNS as the DNS Resolver/Blocker. A few days ago, I started seeing “406 Not Acceptable (openresty)” on several websites.

I’ve whitelisted openresty.org just in case, but it still doesn’t work. It does work if I disable the AdBlocker entirely. How do I debug this?

Running a mailing list is too complicated. RSS and ATOM are infinitely simpler than maintaining a mailing list.

Or, just run a telegram announcement channel.

Overcoming email spam filter is a lost cause because of the spam issue of push notification systems like email. Push notification systems that allow anyone to send messages to you will not scale well beyond personal correspondence and receiving subscribed notifications from forums and github.

Pull notification systems like RSS, ATOM, telegram announcement channel, etc, ... are much better because they have zero spam issue, and there is no spam filter to overcome.

Yeah, this is the kind of material that shows that any attempt to prevent/hamper meta-programming or punt it to preprocessors is at best misguided. It also feeds the smug Lisp weenie within me.

Lisp's acolytes been liberated from the rigid asceticism of lesser faiths. Thanks to Macro and

Not exactly the same… But recently I wanted to pick a library in Python or Julia for simulating differential equations using a GPU. So I asked ChatGPT which libraries exist for this (JAX, CuPy, etc.), asked it to generate code to solve e.g. the 2D heat equation on a 1000x1000 grid for 100 time steps using each of those frameworks. Then I stepped in and verified that each code appeared to do the same thing, and proceeded to benchmark their performance on my hardware. Afterwards I had an informed choice of which framework to use for my project, even though ChatGPT gave me the benchmark code instead of the answer.

What do you mean, 50 years ago? Go to any smallish town in German and you’ll find a farmers market about once a week, with people shouting at passerby’s to buy their cheap produce. Probably the same in most European countries, and I’d wager in many other parts of the world?
One thing I’ve noticed from American colleagues talking about healthcare stuff (insurance and copays and vouchers and HSAs and so on and so forth) is that it’s just mind-numbingly complex. It just seems like an incredible mess. Like, the amount of mental energy that goes into it just from the users has to be a significant cost to society.
Yes, because those paintings were preserved as paintings. And they were not designed in the first place to look like something other than a painting.
They create a new address and from it they publish a revocation of the old address. Then they re-register their content and associate it with payment patterns that pay out to the new address. Then they propagate the new address in-person. When fans trust the new address, their client notices the conflict and they're prompted to prune the old one (since the trust-score on the new one is higher).

If the artist-fan-trust-relationship is multi-hop, it may take a little while for the switch to propagate from fan-to-fan rather than from artist-to-fan, but when it does they'd be notified to consider making the same change.

Meanwhile, a timer has been going since the last time the artist collected funds from the account with the lost key. Once it gets suitably high, the pending payments into it are reversed back to the fans, and the pattern is altered to exclude the abandoned address and notify payers that they might be a better pattern to use, prompting them to find and use the new pattern.

It's not the simplest way, but it's the best I can do without having anybody on payroll, which means maximizing the amount received by the artists.

Besides, art is supposed to be transformative, not status-quo preserving. Even though 99% of artists don't have to worry about being censored directly, I think they're more likely to be interested in protecting the 1% who do. That means having both groups using the same payment rails, and they must be rails that don't respect the kind of bullies that freeze accounts based on content.

Finally, you can lean on this web of trust for the distribution of things like concert tickets, making life more difficult for scalpers (and you can identify the scaplers who have infiltrated your fan network, and explicitly distrust them for next time).

> SpaceX is a perfect storm of a benefactor with unbelievable wealth being able to hoard the best engineers money can buy.

Musk began SpaceX with $100 million of his own cash, almost his entire wealth from having been the majority owner of PayPal when eBay bought it; lots for you and me, but not so compared to the budgets of the Boeings and Airbuses of the world. He and it certainly didn't have infinite amounts of capital during the years it developed Falcon and Dragon, and both came very close to bankruptcy early on. Until Tesla's market cap blew up during the COVID-19 era, Musk had a "mere" few tens of billions of dollars.

In any case, infinite capital guarantees absolutely nothing. Jeff Bezos has been among the world's wealthiest men for far, far longer than Musk's entry into that group. He founded Blue Origin, his own rocket company, before Musk founded SpaceX, but Blue Origin has yet to send a single rocket to orbit. Let me paraphrase an excellent comment I saw on Reddit, in response to one of the usual lies about how the only reason SpaceX is a decade ahead of the rest of the world is that it got zillions in subsidies from the US government:

>If large amounts of funding is the only thing required to succeed, Blue Origin would now have a nuclear-powered spacecraft orbiting Pluto.

You're not wrong. Business is a tough environment.

At a gut level the post seems sensible to me, and it does generate a lot of ideas about how I can make my own docs better. That's not enough, though, if I want the folks who think about docs at my org to change their approach.

As the OP states in several other comments, most writers and organizations learn to prioritize task-based documentation. If we want to adopt a better way of doing things, we need to be able to communicate why it's better. It's no different in other disciplines.
That’s part of the idea behind VAG’s MEB platform and GM’s Ultium and the platforms based on it. Ford is using MEB and Honda is using Ultium platforms for the moment.

I think the issue with unibody cars is eventually you’re constrained on how much a base platform can be changed without the OEMs’ commitment to modifying the layout. The Honda Prologue and the Blazer EV have the same silhouette.

> Anecdotally anyone can talk to a few doctors and find out just how much time they spend on updating charts/documenting information that's not directly relevant to the care, its just to protect against liability or work with insurance.

It’s not just for that. Documentation and checklists exist in public health systems, too, and IIRC there’s some fairly hard evidence that they do reduce errors. Doctors hate them, tho.

I was in hospital a few years back for a fairly inoffensive surgical procedure (public hospital, though in Ireland’s rather weird hybrid system, because I had private insurance my insurance was paying), and I’d say I was asked at least ten times if I was allergic to anything, and had the barcode on my wristband read more times than I can count. This was extremely irritating… but apparently it does _work_; some patients don’t always give the same answer to that question every time.

My thoughts on CoT and the extent to which it "elicits reasoning" align almost perfectly with the criticism of Rao Kambhampati and his students:

https://arxiv.org/abs/2405.04776

Their argument is that CoT can only improve performance of LLMs in reasoning tasks when the prompter already knows the answer and can somehow embed it in their prompt. The paper I link above supports this intuition with empirical results, summarised in the abstract as follows:

While our problems are very simple, we only find meaningful performance improvements from chain of thought prompts when those prompts are exceedingly specific to their problem class, and that those improvements quickly deteriorate as the size n of the query-specified stack grows past the size of stacks shown in the examples. We also create scalable variants of three domains commonly studied in previous CoT papers and demonstrate the existence of similar failure modes. Our results hint that, contrary to previous claims in the literature, CoT's performance improvements do not stem from the model learning general algorithmic procedures via demonstrations but depend on carefully engineering highly problem specific prompts.

And if that's the case and I need to know the solution to a reasoning task before I can prompt an LLM to solve it- then why do I need to prompt an LLM to solve it? Or, if I'm just asking an LLM to generate the Prolog code I can write myself then what's the point of that? As I argue in another comment, an LLM will only do well in generating correct code if it has seen some sufficient number of examples of the code I'm asking it to generate anyway. So I don't think that CoT, used to generate Prolog, is really adding anything to my capability to solve problems by coding in Prolog.

I have no idea how o1 works internally and I prefer not to speculate but it doesn't seem to be some silver bullet that will make LLMs capable of reasoning.
Wonder how much it factors in that in Australia the main choice is between Chinese EVs and Teslas that are also made in China.
The economy is not a zero sum game because we produce more stuff. Money, however, is a zero sum game unless you are Jerome Powell. We produce more stuff because we work hard to produce it, not because venture capitalists have larger bank accounts.

Especially in relation to open-source software, this should be obvious. Software exists because someone wrote it, not because a company owner was paid for access to it. Programmers may be paid to write software. However when comparing two worlds, one in which a programmer wrote some software for free, and another in which a programmer was paid $1 by a venture capitalist who received $5 from a customer who is now out $5, it's not at all clear that the second world is better. Especially since in the second world, the customer has to keep paying and has to contend with software full of ads that make it slow.
Every solution to any problem is trivial once the correct problem has been identified.
I agree but also I think I could be clearer about the key advantage of the distributed many dbs model… it’s that I don’t have to care if people are good at anything that you said :). If teams want to do dumb things with their schema, fine, that’s on them and they’ll have to deal with the consequences. If it matters, they’ll learn and get better. If they want to buy their way out of it with their latency and infra budget instead, that’s honestly fine too.

With many smaller databases owned separately, the blast radius of bad db decisions is small/local.

Curious about the latency of this. This[1] page, which is from 2022, seems to indicate that the CLX memory controllers adds about 200ns, and you got some retimers which add a few tens of ns. Then there's the cabling, assuming 2/3 the speed of light that's 5ns per meter.

With the memory latency itself it seems this adds up about 350ns, while a local memory hit is about 100ns[2][3].

For random access workloads this is certainly better than not having stuff in memory, but I guess for streaming workloads a sled full of NVMe drives might be just as good.

I didn’t know, but according to Wikipedia we don’t need to require `n` to be prime, because when it isn’t, then neither is 2ⁿ-1. https://en.wikipedia.org/wiki/Mersenne_prime

So I prefer to shorten the definition to "A prime of the form 2ⁿ-1". It’s bloody useful that n has to be prime though: makes searching that much faster.
I think it depends heavily on the sub. E.g. in some subs it's an instant permaban from the sub for self promotion, and in others they don't really care one way or the other. Either because there's so little promotional spam in that sub, or something else.
