> The script uses the fastnbt cargo package to interact with Minecraft's world format

At first I was like damn, he made a way to interact with the world map, but apparently there is a library for that! Who would have known.

Cool project nevertheless.

I wonder about the performance claims though.

> Performance Optimization: Utilize Rust’s memory safety and concurrency features to optimize the performance of the world generation process.

Is not much of an answer of performance.

What were the limitations in Python, and how did Rust help?

Since it relies on third-party libraries, what are the optimizations that the author did indeed implement as opposed to the Python version?
The union trick is actually defined in C.

And note that while char can alias anything, the reverse is not true: i.e. you can't generally cast a char array to anything else and expect sensible behaviour. There are ways to make this work (placement new in C++ for example), but it is not a way to escape TBAA: if you store a float in char array you can't then cast it to int with impunity.
There is something that resets permissions, but only those that were granted and only if the app hasn't been used for a while. I'd find it annoying if I intentionally selected "always" for some given permission in an app I regularly use, only to have it occasionally reset itself. I already find the battery optimization notifications for apps I want running in the background annoying enough.
> They look hideous to me. The composition of colors and irritating fonts is just so over the top and distracting.

They look better than Windows 10 or 11. At least the GUI elements are visible, titlebars are titlebars and scrollbars have the right width and arrows.
This same type of logic can be applied with other devices and media.

Basically a workaround ordeal to overcome a lngering defect in current Windows where the supposedly-reliable regular installation process still fails miserably quite often.

Compared to Linux it's a little bit embarassing when Linux has gotten more & more reliable with GUI alone hardly ever failing any more, across various devices and media, which is exactly what you need with such a wide spectrum of configurations out there.

That's why they call them PC's and not Mac's.

I've mentioned this before but the need for the command line in Windows is growing exponentially while in Linux it continues to decline slowly, but at least that's a noticeable improvement for Linux.

The sad part is that not that many decades ago you could go for years at a time in Windows and accomplish all kinds of advanced things without needing the command line at all.

That was kind of the idea of Windows to begin with, so nobody would need a DOS prompt any more.

Just be ready to repurchase all the content you already own on another VR platform like steam, and link the device to your Zuckerberg universal id.
Yeah, I've always used ThinkPads and while IMO they're on average good devices, you better not buy the wrong series and/or iteration.

The LX40 had an atrocious clickpad. The previous LX30 had serious WiFi issues, that I fixed by swapping the card, but it was overall the better device. Then there's issues with trackpoint drifting. On my oldest one the trackpoint simply died.

On my e495 I'm getting weird driver issues, like Windows replacing the AMD graphics driver with a different one, so the Radeon control panel won't load and I can't control that useless VariBright feature. I can prevent Windows from doing this, but then one day the driver was just... gone and I've concluded that it's just better to let Windows do its thing. Also, crashes in Teams with too many windows open and while sharing, seemingly regardless of driver. Weird audio fuckups where the audio output craps itself randomly and starts crackling until reboot (fixed by installing an old Conexant driver and locking it down with group policy).

Also, they make some questionable design choices, like swapping Fn and Ctrl, which you can at least undo in BIOS. My newest one (E16 Gen2 Intel) has FnLock enabled by default (wtf?). Gotta ask why they even removed the separate utility bar above function keys in the first place. And then there isn't even buttons for media control anymore...

Also, don't get me started on Lenovo (Commercial) Vantage, which is an incredibly invasive and janky piece of software, but it does let me limit charging.

For some very fortunate reason I've never had sleep or hibernation problems. Feels like I dodged many bullets over the years.
Both of your claims are way off the mark (I run an AI lab).

The LLMs are good at finding bugs in code not because they’ve been trained on questions that ask for existing bugs, but because they have built a world model in order to complete text more accurately. In this model, programming exists and has rules and the world model has learned that.

Which means that anything nonstandard … will be supported. It is trivial to showcase this: just base64 encode your prompts and see how the LLMs respond. It’s a good test because base64 is easy for LLMs to understand but still severely degrades the quality of reasoning and answers.
Is it just an open secret that the models are currently just being hardcoded for random benchmarks? Seems weird that people would be asking Putnam problems to a chatbot :/
It's not (unless you mean "by popular convention", which actually is not necessarily that popular).

int* c is perfectly valid syntax

and so is int * c.

The latter is my preferred convention: it helps me think of the asterisk as an operator, which, when acting at the "declaration" level, is binary in nature.

Whereas when the asterisk is used at the 'expression' level, it is unary in nature, and can be thought of effectively as a completely different operator that happens to share the same name/symbol as the declaration-based one.
I hope someone reruns this on o1 and eventually o3.

If o1-preview was the start like gpt1, then we should expect generalization to increase quickly.
My comment did not refer to the article at all. It was if they had read the link to the law they pasted. Which near as I can tell they hadn’t, because the content of the law is the opposite of what they are asserting it is.

Feel free to check the law yourself if you’d like.
Not hardcoded, I think it's just likely that those problems exist in its training data in some form
How would plumbing and wiring work? The article states that the wall is a semi-hollow, corduroy pattern, so do the printers leave openings in the walls so pipes/wiring get shoved into them after?
Regarding pre-processing, I feed the result of `clang -E` to the code-generator. Since I use a unity build (single translation unit), it works out fine. In fact, the parser treats pre-processor directives as comments (to work around #line and `-dD`, etc.)

Regarding external and intrusive, I used to do it in the intrusive way but found it too limiting. Here, I not only generate code but can also (potentially) add whole new extensions to the language. This was the reason I wrote a new parser instead of just using libclang's JSON AST dump. Well, that and the fact that libclang is a multi-MB dependency while my parser is ~3000 lines of C code.
I was a couple blocks from the scene in an office. There were cops on every block even before the incident so we can be sure they tried immediately to stop the vehicle. A key point is that the main barriers at Bourbon and Canal are normally just sawhorses. The bollards on the side just served to narrow traffic. I didn’t see the extra barriers at issue tonight but apparently there were some.

Show HN: Built a tool to integrate OpenAI, Claude and Gemini in few hours
I work 9-5 as a software developer and also take on some freelancing projects.

I observed that all clients face some common issues when integrating AI into their applications.

I have received many project requests that start with multiple AI models because clients want to see which AI models generate the highest quality output. However, once they understand that adding more AI models will take more time and money, almost every one of them narrows the options down to just one AI model.

Initially, I also suggested to clients to use the UI provided by each AI model provider. However, the actual output differs when developers implement it, because developers always ask AI to return JSON, which results in inconsistent outputs.

Also, the same prompt does not work for every AI model. For example, if your prompt works with OpenAI, it may generate a different output in Gemini. If not handled correctly, this could even crash your website. Every time this happens, I have to ask the client to provide an updated prompt for that specific AI model, and once again, I need some time to code it.

Because of all these issues, I thought, why not to build a product that implements everything I've learned over time.

That's how I built plugai.io. You will get a dashboard and a public API. From the dashboard, you can configure input/output schemas and prompts, and you can trigger those prompts using the public API. This way, your developers won't have to deal with prompts, they will only need to make an API call to PlugAI, and everything else can be configured using our dashboard. Currently, I have added 12+ AI models from OpenAI, Claude, and Gemini. You can also add multiple variants for the same prompt, and each variant will be triggered for a specified AI model.
I think at a certain point, people who are into conspiracy theory stuff get so used to accepting ridiculous stuff that ridiculousness becomes a virtue for them, and you get this spiral into more and more extreme/absurd ideas being accepted.
The fun thing about control theory in CS is that (in my experience) it's far easier to build accurate simulations or even run scaled down experiments than it would be in a physical setting.

Well your comment just emphasizes how overdue semantic diffing is, really.
Depends a lot on what you want to do.

- What kind of vehicle do you want? A fixed wing? A multicopter? Something else?

- What kind of payload do you want? A stabilised camera (i.e. camera + gimbal)? Something else?

If there is a DJI drone that does what you want (i.e. a multicopter with a gimbal and a camera), then you can't beat DJI.
Isn't that just the LLM equivalent of hardcoding though?

Having burried a bunch of boxes with cards inside is art?

There isn’t a chance in hell we’d get enough states to agree to modify 2A in any way, shape, or form. The amendment could explicitly say, “no private citizen may own or otherwise have in their personal possession nuclear weapons with a yield >= 1 kT,” and red states would still loudly complain that it was a slippery slope to banning personal firearm possession.

Jefferson was right when he said the Constitution should be rewritten once per generation.

> If only.

I will admit that "no problemo" made it sound easier than it actually is. But in the past I considered it literally impossible whereas these days I'm confident it is possible, using well known techniques.

> There isn't a data bank of millions of images of cut / uncut grass

True - but in my case I literally already had a robot lawnmower equipped with a camera. I could have captured a hundred thousand images pretty quickly if I'd known it was worth the effort.

> With something like a lawnmower, you don't want it to kill people or run over flowerbeds.

I agree - at the time I was actually exploring a hybrid approach which would have used landmarks for navigation when close enough to detect the landmarks precisely, and cut/uncut boundary detection for operating in the middle of large expanses of grass, where the landmarks are all distant. And a map for things like flowerbeds, and a LIDAR for obstacle tracking and safety.

So the scope of what I was aiming for was literally cut/uncut grass detection, not safety-of-life human detection :)
This result is the same as a recent test of the same method+hypothesis from a group at Apple, no? I don’t have that reference handy but I don’t think I’m making it up.

I've always assumed they removed it, because it's such a basic and fundamental part of ML training that you separate your test and train data. And yet I never see any papers even mention if/how they do this. And I wonder if they do, how do they guarantee with high reliability that their massive terabytes of data don't contain the answer.
I think you are probably referring to the following paper: https://arxiv.org/abs/2410.05229

They should start by comparing their Anafi to a DJI Mavic for mapping. If I make a map with an Anafi, how does it compare to one made with a Mavic?

Because even a 10k Anafi USA does actually compete with the Anzu Robotics alternative. So if it's good enough for surveyors, there is definitely a market in the US.

I just don't understand why Parrot doesn't do that.
Nothing about opinion or fallibility here. The latter is theoretically possible, but practically senseless. In a very literal way. There is 0 purpose to have something visual that is not intended to be consumed visually. What is a picture that is never seen? This is actually very similar to the philosophical question of whether or not a tree falling in a forest with nothing to hear it makes a sound, but this isn't philosophy we're dealing with.
Huh?

> Mayor LaToya Cantrell described the incident as a "terrorist attack" but FBI special agent Alethea Duncan later said it is "not a terrorist event", instead saying there have been "improvised explosive devices" found in the area.

Ethics is the study of morality. And while you're correct that people have subjective ideas of morality, it absolutely does not matter for the sake of this conversation. You are detracting.

Just because in some place a practice is considered to be okay (morally, whatever), does not mean it is okay, has to be tolerated without comment, and is beyond criticism by those with differing views.

Just based on the value of fairness and that punishment should be decided in an actual court, not the court of public opinion or handed out by some guy named Brian, it is wrong regardless of where it occurs and I've made my reasoning for that pretty clear in this thread. I stand by that and you are still free to make some actual argument to the contrary. If the argument is just "in this country a lot of people feel it is fine", that's okay, just not very convincing to anyone I would imagine.
Sure, no spiral, but I still find the associativity of modifiers confusing. For example could you tell the difference between & mut &, & & mut and & mut &

My wife writes a little, but reads a lot. One time she went back and re-read something she had written years ago, and came away thinking "I hate this type of writing! It thinks it's so damn smart!". Her takeaway was this: if you're in love with the way you phrased something, rewrite it.

Hey goal is to write a story with plot. Real characters. Arcs. As soon as she finds herself wasting time rolling sentences around her mouth, like toffee, with big fancy words, she is directly hurting the readers' flow. Sometimes it's nice to leave one or two, but in general you shouldn't try to be in love with every sentence you've written. But every sentence should move the story forward. Just tell the damn story. Because when you come back to your writing years later, it's those very stylish, witty, fancy phrases that will embarrass you.

It tends to be tricky to do this without wasting a lot of power, most thermostat auto modes have a pretty wide spread of maximum and minimum temperature because otherwise you run the risk of oscillating between using energy to heat and using energy to remove the heat you've just added.

I don't think llm generalise much, that's why they're not creative and can't solve novel problems.
It's pattern matching with a huge amount of data.

This would explain o1 poor performance with problems with variations.
o3 seems to be expensive brute forcing in latent space followed by verification which should yield better results - but I don't think we can call it generalisation.

I think we need to go back to the drawing board.

(grammar nazi mode on) Terrorists usually have a goal (whether good or bad), to extort something from the terrorized person/group. A non-terrorist does does things without expecting much from the victims.
Or it's time to step back and call it what it is - very good pattern recognition.

I mean, that's cool... we can get a lot of work done with pattern recognition. Most of the human race never really moves above that level of thinking in the workforce or navigating their daily life, especially if they default to various societally prescribed patterns of getting stuff done (eg. go to college or the military <Based on <these criteria>, find a job <based on the best fit with <this list of desirable skills & experiences>, go to <these places> to find love....)

The trouble there is that people can experience altered states of consciousness where they are still aware, but lose that sense of self. It's hard to call that state unconscious, but it's also without self-awareness.
that’s not what the story says. in any case, the point is to explain, in terms of dualistic if-then logic, that the if (you practice now) and then (you will wake up) are a single non-dual thing. but to communicate in in terms which make sense to the dual, if-then mind, one needs to use dualistic language.

My own interpretation (which effectively matches the right-left rule, at least algorithmically) is that, (), [], and * are operators, which have different semantics at the declaration vs the 'usage/expression' level, where:

() and [] are right-associative unary type-operators, with high fixity, (or equivalently, binary type-operators when () or [] have arguments)

and * is a binary type-operator, with low fixity (i.e. lower than () or [] ), where the 'left' argument is effectively the context that's left after removing the asterisk and the 'right' argument (rather than what's to the left of the asterisk in a purely 'anatomical 'sense')

(whereas, at the expression level, * is a unary value-operator instead, while () and [] behave the same as in their type-form, except acting as value-operators instead)
