schmorptron··on Intel Announces Inference-Optimized Xe3P Graphics Card with 160GB VRAM
Rumor has it (according to MLID, so no one knows whether it's accurate) that AMD is also looking to use regular LPDDR memory for some of it's lower end next gen GPUs to not have to contend with nvidia over limited and cartelled GDDR7 supply. Maybe they're going to increase parallel bandwidth to compensate it? Or have wholly different tricks up their sleeve.

Maybe not that low, but given it's using LPDDR5 instead of GDDR7, at least the ram should be a lot cheaper.

Xe3P as far as I remember is built in their own fabs as opposed to xe3 at TSMC. This could give them a huge advantage by being possibly the only competitor not competing for the same TSMC wafers
schmorptron··on Meta Superintelligence Labs' first paper is about RAG
One thing I don't get about the ever-reoccuring RAG discussions and hype men proclaiming "Rag is dead", is that people seem to be talking about wholly different things? My mental model is that what is called RAG can either be:

- a predefined document store / document chunk store where every chunk gets a a vector embedding, and a lookup decides what gets pulled into context as to not have to pull whole classes of document, filling it up

- the web search like features in LLM chat interfaces, where they do keyword search, and pull relevant documents into context, but somehow only ephemerally, with the full documents not taking up context in the future of the thread (unsure about this, did I understand it right?) .

with the new models with million + tokens of context windows, some where arguing that we can just throw whole books into the context non-ephemerally, but doesnt that significantly reduce the diversity of possible sources we can include at once if we hard commit to everything staying in context forever? I guess it might help with consistency? But is the mechanism with which we decide what to keep in context not still some kind of RAG, just with larger chunks of whole documents instead of only parts?

I'd be extatic if someone who really knows their stuff could clear this up for me

schmorptron··on Show HN: The Little Book of C
Oh wow, I would not have caught that. I had a look at the first couple of pages, and as not-a-C-expert, it looked pretty solid to me. Readjusting our heuristics to generated slop (or even non-slop?) is gonna take so much more energy than before.

Although I've also been thinking about the overall role of effort in products, art, or any output really. Necessary effort to produce something is / was at least some indicator of quality that means that the author spent a certain amount of time with the material, and probably didn't want to release something bad if it meant they had to put a certain threshold of effort in anyways. With that gone, of course some people are gonna get their productivity enhanced and use this tool to make even better things, more often. But having to expend even more engery as a consumer to find out whether something is worth it is incredibly hard.

Oh wow, a lot of focus on code from the big labs recently. In hindsight it makes sense that the domain the people building it know best is the one getting the most attention, and it's also the one the models have seen the most undeniable usefulness in so far. Though personally, the unpredictability of the future where all of this goes is a bit unsettling at the same time...
schmorptron··on The issue of anti-cheat on Linux (2024)
Valve have been trying by training a neural net that watches every competitive cs:go match played to detect aim bots since 2017 with training data sourced from players labelling demos as cheats or no cheats, but I don't think they've hit a big breakthrough yet
schmorptron··on The Framework Desktop is a beast
Will we be able to get similar bandwidth with socketed ram with CAMM / LPCAMM modules in the near future?
schmorptron··on GPT-5 leaked system prompt?
I was about to to comment the same, I don't know if I believe this system prompt. It's something that ChatGPT specifically seems to explicitly be instructed to do, since most of my query responses seem to end with "If you want, I can generate a diagram about this" or "would you like to walk through a code example".

Unless they have a whole seperate model run that does only this at the end every time, so they don't want the main response to do it?

schmorptron··on GPT-5
To them, and for optimizing for user engagement, it probably is... The future product direction for these is looking more, not less syncophatntic
schmorptron··on Perplexity is using stealth, undeclared crawlers to evade no-crawl directives
Isn't that only because they offer unpaywalled versions to web crawlers in the first place, so they still get ranked in search results?

if the establishment lets that happen it would be incredible for the US imo. But weren't there also pushes for her to get fired even if Harris got elected? Of course not as strong or immediate as it happened with Trump, but the Lobbies weren't happy either way...

if the way they are explicitly starting to optimize llm chats for engagements and friend-like behaviour, he'll just need to switch around some letters to call it Mate

In the blog post they say as much that it just is a system prompt. Still nice to have easy access, and for more users to discover that use case.

I'm conflicted about this. Custom tutoring available at all times and at mass sounds like a great thing, if done right. On the other hand, the research skill you mentioned is something that I worry about atrophying as well. Where before, we used to read through 3 or 4 slightly related articles or stackoverflow questions and do the transfer of related topics onto our specific problem ourselves, with a tutor it's all pre-chewed.

Then again, human 1:1 tutoring is the most effective way to learn, isn't it? In the end it'll probably end up being a balance of reading through texts yourself and still researching broadly so you get an idea about the context around whatever it is you're trying to do, and having a tutor available to walk you through if you don't get it?

Oh, that's pretty good! I've been doing this with various LLMs already, making elaborate system prompts to turn them into socratic style teachers or in general tutors that don't just straight up give the answer, and have generally been impressed with how well it works and how much I enjoy it. The only thing to watch out for is when you're talking about something you don't already know well it becomes harder to spot hallucinations, so it's a good idea to always verify with external resources as well.

What these really need IMO is an integration where they generate just a few anki flashcards per session, or even multiple choice quizzes that you can then review with spaced repetition. I've been doing this manually, but having it integrated would remove another hurdle.

On the other hand, I'm unsure whether we're training ourselves to be lazy with even this, in the sense of "brain atrophy" that's been talked about regarding LLMs. Where I used to need to pull information from several sources and synthesize my own answer by transferring several related topics onto mine, now I get everything pre-chewed, even if in the form of a tutor.

Does anyone know how this is handled with human tutors? Is it just that the time is limited with the human so you by necessity still do some of the "crawl-it-yourself" style?

schmorptron··on The Minecraft game score unexpectedly became big business for its composer
I understand this, and also partially feel this way as in it's garbo that they won't allow the artists to own their work and are able to strongarm this due to the size of Minecraft. On the other hand, I like a lot of the new tracks they've added as well and Lena Raine and the others have done a great job capturing the vibe while not just ripping off C418.
schmorptron··on Linux Reaches 5% Desktop Market Share in USA
I'd start that conversation from another perspective. If someone uses linux, not caring that it's not windows, then that's a milestone.
schmorptron··on Games run faster on SteamOS than Windows 11, Ars testing finds
i wonder how much of that is simply due to how incredible dxvk is. I think intel even uses it as part of their windows drivers to translate some older dx version games to vulkan because it performs so much better on their cards.

schmorptron··on Game Hacking – Valve Anti-Cheat (VAC)
Woah, cool to see a bit of how it all works. Seems similar to basic antivirus signature checking? As a side note, a few years back, they had a GDC talk about a (then-new) machine learning based approach to catching cheaters. Regardless of how it worked out, I found it fascinating. The presenter delivered the problem and solution approach so well I'd still like to work on something like this some time. I think they're still updating this for CS2, so it would be really cool to see how far it's gotten now.

schmorptron··on Just How Many More Successful UBI Trials Do We Need?
This applies less for basic human needs like a roof over the head, especially in a supply constrained market like we've been in for quite some time in many places around the world
schmorptron··on For algorithms, a little memory outweighs a lot of time
As an aside, I really enjoy a lot of the quanta magazine articles! They manage to write articles that both appeal to compsci people as well as interested "outsiders". The birds-eye view and informal how and why they pack into their explanation style often gives me new perspectives and things to think about!
schmorptron··on Try Switching to Kagi
FYI, I think the $10 plan that's now "basic AI" used to just be the unlimited search plan and they just recently added a limited capacity of the AI stuff to it.
schmorptron··on Firefox tab groups are here
Yeah, I'm using them as soft bookmarks. Turn them into hard bookmarks every month or so, not to actively look at them, but the firefox address bar searches in bookmarks as well and offers them up first when typing, so I have a repository of things I've declared interesting / cool / good before that I can refer back to when typing keywords into the address bar. Messy, but it works! I must have a couple tens of thousands of bookmarks by now...
schmorptron··on We're Raising Kids to Prefer AI over People–and No One's Noticing
Don't have kids myself, but as a source, I was once a child. Isn't the big problem then even if you do limit the time, it then becomes an even bigger want because we always want what we can't have? What's your experience with this?

I've seen a twitter thread where a woman described conditioning her son to find screens boring at an early age by only showing slow train riding footage on screens around the house at all times when the kid was around, which is interesting. I wonder if that'd work well in general or just for that one specific child. It'd probably fall apart as soon as the child gets introduced to the fact that cool dopamine hacking content does exist on screens?

schmorptron··on Apple needs a Snow Sequoia
I've only started using gui search since using fedora. the tracker search in the activities view is fast and finds files in the home folder by name pretty well. The only shame is that the pdf-content search doesn't work in the main search interface but only when searching in the file manager.
