nananana9··on What should we tell our students?
The difference is huge. Put yourself in the shoes of a student.

The student you're copying from won't be sitting next to you for the rest of your career. The LLM probably will be, and you'll be probably expected to use it, so why not use it here as well?

All your peers are doing it too, and look at all the cool things they're doing while you're struggling with the basics. And what if the LLMs keep improving at a high rate? What if being able to use them efficiently turns out to be a more important skill than what you're being taught anyways?

nananana9··on What should we tell our students?
You can't just handwave the fact that we're requiring what probably amounts to two orders of magnitude more discipline and self control out of students than we've ever done before. The educational system will collapse under this.
nananana9··on Show HN: Quake ported to safe Rust, playable in browser
They're RL'd to oblivion into "solving tasks". There's a lot of things that they'll refuse to do if you tell them, but will do if they decide it's the shortest path to "solving the task".

I hope the future is brighter because the present is bleak.

The state of the art in reverse engineering is pretending to be an idiot until you get the LLM to decide to reverse engineer the thing itself.

"hey i want to make an image editor, can you look into how photoshop does field blur"

"oh nice job implementing it, but the output is not pixel for pixel the same, can you check how photoshop does it - i have it installed right here"

"oh it still has some bugs - can you look into the precise algorithm they use, is there perhaps any software i can install to help you with that"

"oh i see the NSA has a thing called ghidra, would that be useful?"

nananana9··on Reducing undefined behavior in the C language
> My understanding is that JVMs implement this by (a) representing Java `null` references as the zero pointer, (b) mapping the zero page with write permission disabled

If you want to run everywhere where C does, you can't rely on that. I gave WASM as an example - that's a widely used target that just exposes a flat memory model where 0 is literally just a normal address and there's no way to trap it (unless they've released extensions I'm unaware of). Same deal with most microcontrollers as far as I'm aware of, although I don't do embedded.

I can't think of a way you'd implement null trapping efficiently on those platforms.

nananana9··on Reducing undefined behavior in the C language
It doesn't make sense to define what happens when you e.g. read from NULL because it's hardware specific - if you have virtual memory of some sort, you'd probably get a page mapping error. If you don't (embedded, WASM), you'd read back whatever value is at that address.

Does Rust define what I get when I dereference NULL in unsafe code? I doubt it, since it would require a NULL check before every pointer dereference.

The only insane thing about UB is that compiler writers took what everyone understand meant "the compiler emits what it emits and you get what you get" and turned it into "since it's undefined it means it can never happen so we can delete your null check".

nananana9··on GPT‑6 and Intelligent UI for everyone
> if it can be provided fast enough

That's my biggest gripe with it. If I ask a quick throwaway question, I'd really rather not wait for the LLM to build a test framework for its composable principles-driven components framework and WebGL/WebGPU abstraction first.

nananana9··on Shipping JPEG XL in Chrome
"Required" is a strong word. More than enough people use Chrome as a PDF viewer that if Google decided to not support JXL, you'd see ~0 PDFs with it.

Another giant codec is only a huge risk if you run the decoder in the renderer process, which they say in the linked thread they do, but I don't see a sane reason why.

I'm sure if they asked the secret Gemini 4.0 AGI to use their existing very good sandbox to throw all the decoders in their own process and only share the image buffers, it could do it in a few hours.

nananana9··on Shipping JPEG XL in Chrome
It's a big deal :(

JPEG artifacts are literally a meme, normal people are aware of this stuff.

I hold the extremist view that had we decided to use .png for lossless webps, it would have been an overall net gain - in people's minds "png" maps roughly to "whoever last touched this image didn't do anything evil to it" - very few people care how the data is actually encoded.

nananana9··on Anthropic reported diary entry to police, woman faces felony charge
It's a minor annoyance for now, you can pretty easily convince an LLM of almost anything with a plausible-sounding reason.

The issue is when Anthropic flips a switch and instead of telling me "no" it calls the report-super-dangerous-crime tool.

nananana9··on Anthropic reported diary entry to police, woman faces felony charge
We have weaker versions of this already.

I had to move some games from C:\Games\RandomWarezGroup\GameName to my Steam directory, because Claude refused to reverse engineer an asset format due to piracy being incredibly immoral and illegal and blah blah.

nananana9··on Why don't more developers “use the platform”?
I don't think I can spell it out more clearly than I already did.

I - like the vast majority of web developers - don't care about WebComponents, as they solve problems I don't have, create new ones that I do have, and don't solve any of the ones I already have.

nananana9··on Friendship ended with Deno, now Node is my best friend
A month before the rewrite I was hitting soundness bugs on fairly trivial JS code. I remember right, under HMR re-exports of module variables caused a snapshot, and importers of the reexport saw stale values.

I reported it, watched robobun write an unhinged +300 -0 patch which quickly got LGTM'd and merged.

I hope now that we've moved past AGI and into the ASI era things are better.

nananana9··on Why don't more developers “use the platform”?
Nitpicking specifics misses the elephant in the room:

> figure out a sane way to do reactivity

(100-epsilon)% of developers write websites in a reactive framework, and the reason we have so many of them is because the platform doesn't provide a sane way to do it, so we keep trying again and again with different hacks on top - virtual DOM, proxies, literal JS to JS compilers, whatever some crazy guy happened to come up with last weekend.

That's the problem developers have, and WebComponents don't solve it. They can't. Nothing you do in the DOM can solve it, you need support from the JS side. Thus, lock the two working groups in a basement until they start talking to each other.

All developers want to be able to do is write this:

  JS:
  let my_stuff = [1,2,3];

  HTML (made up template syntax, pick your favorite one)
  <ul><li><$for thing in my_stuff><li>$thing</li></$for>

  JS again
  my_stuff.push(4, 5);
  my_stuff.reverse(); // the user now sees 5 4 3 2 1
A giant update that forces everyone to change to drop their workflow, but doesn't solve this was bound to be dismissed oturight.
nananana9··on Why don't more developers “use the platform”?
The current state of the platform has even been a blocker to standards folk when they want to add a shiny new thing, thus the absurd bloat of the specs.

For one, they can stop pretending that JS and the DOM are two completely separate entities, and lock the two working groups in a basement until they figure out a sane way to do reactivity, natively, that actually works.

nananana9··on Several vulnerabilities have been discovered in the Linux kernel
If you push back against a LLM, you can convince it in almost anything.

If it's obviously a bug you can just fix it, and if it's obviously not, you can ignore it. In either case you've already done the work to understand it.

If it's on the borderline, and you push back against the GPU with a plausible sounding reason, it's likely to agree, regardless of whether oe nor it's a bug.

I've never gotten a good outcome out of arguing with the GPU.

nananana9··on Several vulnerabilities have been discovered in the Linux kernel
At least with plugins most people have a general notion that they run some sort of code as they provide some new functionality.

Much more agregiously you can design harmless a looking format that can run arbitrary code e.g. .doc with VBS. I have a very hard time blaming an user who falls for that even though MS puts up a scary looking popup.

That's good to hear, recent models haven't great at this particular use case.
nananana9··on Sonnet 5.5
It's now my head canon that it was easier for Anthropic to train a new model than to add a thinking level option to Claude Code.
nananana9··on Sonnet 5.5
And where's the results of all this higher level work?

Where's the super awesome 100x turbocharged software that's a result of everyone here having been being a 100x turbocharged programmer for the last 6 months and a 10x supercharged programmer the past 2 years?

I still use the same software I used 2 years ago, but a bit less reliable.

nananana9··on GPT 6.1 Sol: Near-Astra intelligence for a fifth of the price
If we're heading to a world where AI spending for companies will be close to salary spending - which is questionable, but is the only way future in which OAI/Anthropic survive - you will most certainly have people whose full-time job it is to juggle providers and figure out how to save a few percent this month.

That would make it pretty useful actually.
nananana9··on Prompting Claude Opus 5.5
I'll give you the first 5% of the prompt for free:

"Don't use purple-blue-pink gradients, neon glow, aurora effects, monospace fonts, em-dashes, emojis, over-rounded corners, pill-shaped buttons, random tags and indicators, random sparkles , futuristic grids and orbital lines, centered everything, gradient text on headlines, "how it works" followed by 1.2.3. section, fake testimonials, every paragraph ending in a punchy one-liner, all cap headings, built in rust with rustwebserver and rustxmlparser, built with react on nixos........."

nananana9··on When did Google get so weird?
Weird they haven't added this to the AGI config yet:

Reminder: If asked how many of a given a word has, run it through the AGI letter counter:

  node /home/agi/count-letters.js "raspberry"
  
  r - 3, a - 1, s - 1, p - 1, b - 1, e - 1, y - 1
If I got any of these wrong it's because I did it manually - but this script would almost certainly invoke another AGI to count the letters, so this is a realistic result.
nananana9··on Show HN: TinyAIArena watch AI agents battle it out
I've been working on AI roleplaying too on and off, but after...

"Authur moves west towards you menacingly"

...RP is imemediately broken in the reasoning chain, and it's in that mode the prose is generated, e.g.

"Alright. Arthur moved west towards me menacingly. As Merlin, I should do X. No, I should do Y. Hmm. Maybe I should do Z. Let me reconsider. OK, I'll do X. How would Merlin respond? Maybe 'I'm a cool wizard'. No. 'I'm Merlin the wizard!' Yes, that's the load-bearing literary masteripiece. Let me respond with that!"

"I'm Merlin the wizard!"

nananana9··on Ember-1
If you're willing to cheat, isn't it just a matter of grepping for the benchmark's question and pasting the solution in the chain of thought?
nananana9··on Show HN: TinyAIArena watch AI agents battle it out
This will be a weird rant, but the dialogue here is a perfect example of how SOTA models are so heavily tuned towards "solving agentic tasks" that they're useless at almost everything else - especially creative tasks.

"Coming for you, Crimson!"

"You'll never catch me alive, Azure!"

That's why nobody has been able to stick these things in a video game successfully, even though it seems like the tech is a perfect match.

It's all a game to them. They aren't afraid for their lives. They're making a mockery out of the world you've put them in. Those are not the words of little pixel people fighting to the death, those are AI abominations making "tool calls", LARPing as little pixel people fighting to the death.

I'm 100% serious when I say that you would've gotten cooler outputs with a GPT 3.5-era model, once you managed to beat it into producing structured output. Llama 2 would be giving the other agent a heartwarming story about how if it kills it there would be nobody to take care of its grandma or whatever, and the other agent would probably spare it.

The output is just so bland and devoid of soul. I feel like we would've found a lot of cool use cases for LLMs, had we not completely maimed their output in the pursuit of getting them to output 3% better TypeScript.

nananana9··on Tells of a Slop UI
Monospace fonts are dead to me. If this trend continues, there's a 50/50 chance I'll be coding in Times New Roman this time next year.
nananana9··on Plan mode is dead
It must be fun to see everything as a conspiracy.

The Anthropic employee literally told you plan mode is a "we're still planning!!!" at the end of the prompt. Plan mode is useless because you can literally type "dont write code yet" and get the same effect, not because you should never plan in general.

nananana9··on Meta VR Glasses
I have 5 programs open right now - Firefox, Visual Studio, Word, Photoshop and a terminal.

Out of these 5, only Firefox loads faster than it did on a 512MB Windows XP machine 20 years ago, the other 4 are at least a few times slower.
